The way to Develop Safe Healthcare Options


The healthcare business in america is a considerably difficult space. There are lots of medical health insurance plans (non-public medical health insurance for almost all and public medical health insurance for low-income individuals and the disabled), many suppliers, and plenty of numerous funds coming from quite a few payers.

The complexity of this multi-layer system, in flip, makes it fairly exhausting to control, management, and defend each single a part of it. That’s the reason many sources are more and more reporting varied leaks of confidential knowledge.

Between January and September 2024, US healthcare organizations suffered 491 main knowledge breaches with over 500 information compromised. Hereby, the determine has risen during the last ten years.

To stop any diploma of data leakage, all medical apps within the US are obliged to comply with HIPAA rules (Well being Insurance coverage Portability and Accountability Act).

On this information, we’ll stroll you thru the whole lot it’s worthwhile to find out about HIPAA-compliant app growth—from important certifications and software program growth phases to widespread errors, prices, and future tendencies.

What’s HIPAA and Why Does It Matter?

Basically, HIPAA is a federal American regulation whose goal is to guard affected person well being info (PHI). It units requirements for the storage, transmission, and entry of healthcare info to keep away from breaches and undesirable entry.

For medical institutions that plunge into well being app growth providers, HIPAA compliance isn’t solely a authorized matter—it’s a dedication to determine belief, keep away from hefty fines, and defend knowledge.

Non-compliance and HIPAA violations can imply financial penalties of 1000’s to tens of millions of {dollars}, along with damaging repute.

Key HIPAA Guidelines and Their Influence on App Improvement

The HIPAA legislation was handed in 1996 with a purpose to make the healthcare system extra sufficient and immediate. The legislators had been conscious that digital methods have the prospect to reveal sufferers’ non-public well being info.

Subsequently, HIPAA was cut up into a number of separate rules that altogether should defend people’ private well being info or mitigate the implications of breaches.

  • The Privateness Rule: The Privateness Rule creates requirements for the use and disclosure of well being info. It protects individuals’s non-public well being information and provides them the suitable to seek out out about using their info. The rule applies to sure organizations, together with hospitals, docs, and insurance coverage corporations, that are referred to as “lined entities.”
  • The Safety Rule: The HIPAA Safety Rule executes requirements for safeguarding digital well being knowledge. It regulates any group that collects or processes this sort of info from corresponding software program, e.g., wellness or physician apps. The rule requires them to have sufficient protections in place—respectable insurance policies, protected methods, and protected storage on bodily units.
  • Breach Reporting: If there’s an information breach, HIPAA Breach Reporting mandates the app supplier to tell customers, the Division of Well being and Human Companies (HHS), and typically the media.
  • The Enforcement Rule: The HIPAA Enforcement Rule encompasses compliance and investigation provisions, analysis of civil cash penalties for violating the HIPAA Administrative Simplification Rule, in addition to procedures for listening to.

Should-Have Options in a HIPAA-Compliant Software program

Once you make a healthcare app that holds confidential affected person knowledge, HIPAA compliance is necessary. However being compliant isn’t a lot about checking bins as it’s about placing sure options in place that safeguard private well being particulars.

App’s Scope and Roles

First, your cell app requires knowledge encryption. This implies all well being knowledge have to be encrypted to unreadable kind when it’s being saved or transmitted. Subsequently even when somebody steals the info, they will be unable to learn it.

Then be sure you have resilient person authentication, which implies solely authenticated individuals (docs, nurses, or sufferers) ought to be capable of log in and see particular info. This may be through passwords, two-factor authentication (e.g., a code texted to your cellphone), and even face ID or fingerprint.

Moreover, you would need to implement role-based entry management. Not all people wants to have the ability to view the whole lot.

For instance, a doctor might want to view medical information, however a receptionist will solely must view appointment knowledge. Position-based management minimizes entry to an absolute minimal of what’s crucial.

Moreover, embody computerized log-out. If an individual forgets to log off of the cell app, it ought to log them out after a brief interval of inactivity to forestall different people from inadvertently accessing confidential information.

In case your utility offers messaging, video calling, or sharing recordsdata, all of these parts should even be unassailable. All communication must be made safe in order that nobody outdoors the applying can pay attention in or see non-public paperwork.

And simply in case issues do go amiss, your app ought to have a breach notification attribute. It must be able to detecting the issue and notifying customers and correct authorities rapidly, as HIPAA requires.

Lastly, keep in mind that it’s an ongoing job to stay protected. Once you develop HIPAA-compliant cell software program, your app should have house for normal updates and safety fixes to defend in opposition to new risks as they’re recognized.

Steps to Construct a HIPAA-Compliant Cellular App

In 2023, it was reported that 35% of US companies that export knowledge overseas stated privateness rules are an added price. Moreover, 17% stated rules had been a notable barrier to cross-border commerce.

But, the absence of a basic knowledge privateness safety legislation on the federal entrance makes any firm conflicting with different states or areas which have extra uncompromising commitments.

Thus, HIPAA-compliant cell app growth providers (irrespective of whether or not iOS or Android) have to be structured right into a course of that features not solely writing the code, but in addition constructing belief, defending well being knowledge, and adhering to strict rules at each step.

Steps to Build a HIPAA-Compliant Mobile App

1. Examine HIPAA Necessities

Earlier than writing a single line of code, begin by getting your self acquainted with what HIPAA requires usually. It’s worthwhile to know what sort of knowledge constitutes protected well being info, what decrees cowl the storage and disclosure of that info, and what technical, bodily, and administrative precautions are mandated.

2. Make clear Your App’s Scope and Roles

Second, explicitly state what your healthcare utility will do, who will use it (sufferers, physicians, staff, and so on.), and what sort of well being knowledge it can management. At this level, resolve whether or not your app is a “lined entity” or a “enterprise affiliate” as a result of HIPAA instructions are barely completely different for every.

3. Associate with an App Improvement Firm

One of many smartest strikes you can also make once you dive into HIPAA-compliant app growth is to accomplice with an utility growth workforce, equivalent to SCAND, that has experience within the subtleties of healthcare software program growth.

A superb accomplice will assist you choose the suitable cell app growth method, select a tech stack for various cell units, and handle implementing all of the required safety features, together with encryption, person authentication, audit logs, and computerized logouts.

They’ll additionally make sure that your app contains acceptable role-based entry management, so customers solely see the knowledge they really want.

4. Check Comprehensively

Compliance and safety testing go hand in hand when making software program. Past useful exams, it’s necessary to check for vulnerabilities, encryption weaknesses, misconfigured entry controls, and logging issues. If possible, rent exterior safety professionals to assessment your app.

5. Put together Your Crew

Ensure that everybody concerned, from app builders to assist workers, understands HIPAA fundamentals. Coaching is part of compliance. Even an awesome app may be made non-compliant when affected person info is mishandled by somebody who isn’t conscious.

6. Carry out Common HIPAA Danger Critiques

Carry out a danger evaluation earlier than launching your app (and recurrently afterward). This may uncover any spots the place your app’s safety, knowledge dealing with, or infrastructure may very well be in danger.

7. Get Authorized and Compliance Signal-Off

Have authorized and compliance professionals assessment your app and documentation previous to going stay. They’ll assure that your app is HIPAA compliant in all respects and assist with the last-minute particulars, equivalent to signing Enterprise Affiliate Agreements (BAA) with any third-party distributors that you just use.

8. Watch, Replace, and Keep Compliant

HIPAA compliance isn’t a one-off exercise—it’s steady. After going stay, proceed to observe your app for exposures, recurrently revise it, and carry out periodic audits to maintain your self in compliance with all the provisions as legal guidelines and expertise change.

Widespread Errors in HIPAA Compliance and The way to Keep away from Them

It’s troublesome to develop a HIPAA-compliant app when even minor errors could cause severe issues, equivalent to knowledge breaches or authorized ramifications. The brilliant aspect is that almost all of them may be bypassed if you realize what to search for.

Common Mistakes in HIPAA

Some of the widespread errors isn’t understanding what protected well being info is. PHI isn’t merely medical information—it’s any particular person info associated to an individual’s wellness. Should you don’t defend any such info adequately, you could possibly unknowingly violate HIPAA tips.

One other widespread mistake is skipping the chance evaluation (you will discover extra about it under). Earlier than you launch your app, it’s worthwhile to examine for potential safety threats.

Many builders both overlook this step or put it off. However if you happen to don’t assess your app’s safety, you’ll be able to’t know if there are defects that want correcting.

Selecting the inaccurate providers and instruments is a frequent mistake too. Not all cloud providers or instruments are HIPAA-compliant. Should you use a service that won’t execute a BAA, it isn’t protected to make use of for the processing of PHI.

Widespread Errors Why It’s a Downside The way to Keep away from It
Not understanding what PHI contains You might by accident expose or mishandle protected knowledge with out realizing it. Be taught what qualifies as PHI—it’s not simply medical information however any health-related knowledge.
Skipping the chance evaluation Safety flaws go undetected, growing the prospect of knowledge breaches. All the time carry out an intensive HIPAA danger evaluation earlier than launch.
Delaying the chance evaluation Suspending it means you may miss vulnerabilities throughout vital phases of dev. Make it a part of your early and ongoing growth course of.
Utilizing non-compliant instruments or cloud providers Utilizing platforms that received’t signal a BAA may end up in non-compliance and knowledge publicity. Select distributors and instruments that explicitly assist HIPAA and supply BAAs.

The way to Conduct a HIPAA Danger Evaluation

A HIPAA danger evaluation is necessary for making certain that your app stays compliant and protects delicate well being knowledge. It might sound difficult at first, however if you happen to break it down into steps, it turns into a lot simpler to deal with.

First, it’s worthwhile to perceive precisely what sort of well being knowledge your app handles. Embrace not simply medical information, but in addition private info like:

  • Names
  • Telephone numbers
  • Insurance coverage particulars
  • Appointment dates

Understanding what knowledge you’re accumulating, storing, or sharing helps you determine what must be protected.

Subsequent, it’s worthwhile to decide who has entry to that knowledge, equivalent to your workforce, sufferers and healthcare suppliers, or third-party distributors. Not everybody ought to have full entry to all the info, so it’s necessary to arrange entry controls that enable customers to see solely the knowledge they want.

As soon as you realize what knowledge you might have and who can entry it, it is best to take a look at your present safety measures. Are you utilizing encryption, safe logins, and correct entry management to guard the info?

You additionally want to think about bodily safety, like how and the place you retailer the info. If there are any gaps in your safety, you’ll want to handle them to remain compliant with HIPAA.

Then, it’s worthwhile to take into consideration the potential dangers to the info. These may come from inside errors, like an worker by accident exposing info, or exterior threats, like hacking makes an attempt. By figuring out these dangers, you’ll be able to determine what elements of your app could be susceptible and what must be improved.

After that, consider the influence of those dangers. How dangerous wouldn’t it be if a breach occurred? Would delicate knowledge be uncovered? How seemingly is it that this may occur? This helps you prioritize which dangers have to be handled first.

Once you’ve discovered the dangers, it’s time to take motion. You may must strengthen your encryption, enhance login safety, restrict who has entry to sure knowledge, or conduct common safety checks.

It’s additionally necessary to doc the whole lot you do in the course of the danger evaluation. Preserve observe of what knowledge you deal with, the dangers you’ve discovered, the safety measures you’ve put in place, and any adjustments you make. That is necessary for HIPAA compliance and can make it easier to throughout audits or if any points come up sooner or later.

Lastly, do not forget that HIPAA compliance isn’t one thing you do exactly as soon as. As your app adjustments and new threats emerge, it’s worthwhile to recurrently assessment and replace your danger evaluation. This fashion, you’ll be able to preserve your app compliant and make sure the knowledge stays protected.

The way to Get a HIPAA Compliance Certification

HIPAA certification is verified by HIPAA coaching to validate the understanding of corresponding compliance requirements, usually performed yearly. Profitable trainees are awarded a HIPAA compliance certificates.

HIPAA Compliance Certification

For a corporation, HIPAA certification is when a third-party verifier confirms whether or not the corporate abides by all of the rules wanted to guard well being info.

Having a HIPAA certificates of compliance is a big a part of proving that your app or enterprise is solely safe, and there are some issues you are able to do to show you’re HIPAA compliant:

Should you meet their audit, they offers you a report or certificates stating you’re compliant, one thing that is essential for displaying purchasers and companions that you’re following the rules.

Value of HIPAA Compliance

HIPAA compliance may be from extraordinarily inexpensive to extraordinarily expensive, relying upon the dimensions and complexity of your group or app. There is no such thing as a fastened price to develop into compliant, however having an thought of the place the prices most frequently lie, you’ll be able to funds accordingly and never be caught off guard.

Cost of HIPAA Compliance

First, it’s worthwhile to contemplate the prices related to implementing the mandatory safety measures:

  • Information encryption
  • Entry management methods
  • Safe login protocols
  • Audit logging software program
  • Safe cloud internet hosting providers (with signed BAAs)

Relying on the applied sciences concerned, these software program options may be costly to deploy, particularly for small companies. Spending on good safety, nonetheless, is the value you should pay for shielding delicate well being info and attaining compliance.

Then, there’s the expense of paying professionals to do a correct danger evaluation and audit your methods. Danger evaluation is a crucial side of HIPAA compliance that checks for weaknesses and enhancements wanted.

Most corporations choose to rent third-party auditors or safety consultants, who usually cost by the hour or have a flat charge. Charges differ however can vary from:

  • $1,000 to $5,000 for small-size assessments
  • $10,000 or extra for large-scale methods or enterprise apps

Additionally on the record is coaching your staff. Since HIPAA requires all staff to pay attention to learn how to deal with the protected well being info appropriately, you’ll must spend money on coaching periods. These bills usually embody:

  • Drawing up or shopping for coaching supplies
  • Paying for entry to on-line programs or certification instruments
  • Giving time for workers to attend coaching periods

One other half to think about is the price of recurring monitoring and auditing. When you might have obtained compliance, you should keep your methods updated. This includes:

  • Inside or outdoors security audits
  • Successive publicity scanning
  • Monitoring instruments to detect and react to doable breaches

Although these bills fluctuate, common inspections are crucial to stay in compliance and keep away from fines.

Lastly, don’t neglect authorized providers. You could have to work with attorneys to develop or negotiate Enterprise Affiliate Agreements (BAAs), and privateness insurance policies, or handle breaches. Authorized charges may embody:

  • Session charges for HIPAA-related authorized questions
  • Reviewing and updating contracts with distributors
  • Help in case of an information breach or compliance concern

By and enormous, HIPAA compliance prices usually fall throughout the following 5 classes: implementation of safety, danger analyses, coaching of personnel, ongoing monitoring, and authorized charges.

Even though the general expense might sound excessive, the funding is important to safeguard affected person information, keep away from penalties, and acquire the belief of customers.

Profitable HIPAA-Compliant Apps You Can Consult with When Creating Your Software program

To higher perceive what it takes to make an app that adheres to HIPAA, let’s check out some examples of apps that efficiently adjust to HIPAA necessities.

How On a regular basis Plastics Quietly Flip Into DNA-Damaging Nanoparticles – NanoApps Medical – Official web site


The identical distinctive construction that makes plastic so versatile additionally makes it vulnerable to breaking down into dangerous micro- and nanoscale particles.

The world is saturated with trillions of microscopic and nanoscopic plastic particles, some smaller than a virus, making them sufficiently small to intrude with mobile perform and even alter DNA. Researchers have discovered these particles in practically each setting they’ve studied, from Antarctic snow to human blood.

In a brand new examine, scientists have mapped out the molecular mechanisms behind the widespread formation of those tiny plastic fragments. Since plastic first entered the market 75 years in the past, its use has turn into practically common—and so has the presence of nanoplastics.

The identical properties that make plastic sturdy and versatile additionally make it vulnerable to breaking down into nanoscale items. This breakdown is very frequent within the 75-80% of plastics categorized as semicrystalline polymers. The analysis was led by Sanat Kumar, Michael Bykhovsky, and Charo Gonzalez-Bykhovsky, professors of Chemical Engineering at Columbia Engineering.

In case you have a look at a bit of plastic by way of a robust microscope, you’ll see alternating layers of exhausting materials and delicate materials. Within the exhausting layers, plastic molecules are rigidly organized in sturdy crystal constructions. Within the delicate layers, the molecules lack construction and type a delicate, amorphous mass.

When hundreds of those layers are stacked collectively, they create a cloth that’s light-weight, sturdy, and very versatile. Importantly these supplies derive their distinctive properties by way of the connectivity between the delicate and exhausting phases.

In a paper printed March 28 in Nature Communications, the researchers clarify how nanoplastics type. They found that the method begins within the delicate layers, which develop weaker over time as a consequence of environmental degradation and might break off even when the plastic just isn’t underneath stress. By themselves, these delicate items break down rapidly within the setting. Issues come up when the failure of a delicate layer permits exhausting layers to interrupt off. These crystalline fragments are the nano- and microplastics that may persist within the setting for hundreds of years and trigger vital harm in dwelling issues, together with people.

We sat down with Kumar to study extra about this work.

How does this paper contribute to our understanding of nanoplastics?

There’s loads of anecdotal proof of nanoplastics — folks have discovered them in all places and seen them type — however nobody had decided the mechanisms behind how they type.

What did you uncover?

75% of all plastic used has kind of a brick-and-mortar construction. It’s manufactured from actually skinny alternating layers: exhausting, delicate, exhausting, delicate, and so forth. We’ve identified because the Nineteen Fifties that the delicate stuff is holding the exhausting stuff collectively.

What we present within the new examine is how simply these delicate connectors break even underneath quiescent situations corresponding to in a landfill. As soon as that layer fails, the exhausting segments have nowhere to go — they scatter into the setting.

Why is that an issue?

These items float round, and a few find yourself in human our bodies. The smallest items go by way of cells and into the nucleus, the place they’ll begin messing with DNA. Nano- and microplastics, which appear to have related configurations and dimensions to asbestos, elevate the potential that they might trigger most cancers, coronary heart illness/stroke, and different illnesses.

Is there an engineering answer to handle this drawback?

Our outcomes recommend that engineering the structure of the delicate layers to be extra resilient would lower the quantity of crystalline fragments that break off.

Clearly, focus must be positioned on this level to scale back the quantity of micro and nano plastics created by regular polymer degradation.

How can higher understanding nanoplastics enhance human well being?

Solely 2% of plastics are recycled, largely as a result of it’s too costly. However for those who simply throw plastic into the setting, it creates micro- and nanoplastics that seem like they’ll trigger well being issues.

If you consider it that method, if it’s a must to select between the well being issues that may very well be created by the nanoplastics vs. the price of recycling, then possibly it’s really cheaper to recycle.

UK’s first water-monitoring centre goals to behave as early warning system for illness outbreaks
Professor Barbara Kasprzyk-Hordern is a co-Director of CWBE (picture credit score: Lauri Lapworth, College of Tub)

The College of Tub is launching what’s described because the UK’s first early-warning public well being surveillance system primarily based on detecting tiny traces of chemical compounds and organic markers present in water.

The Centre of Excellence in Water-Primarily based Early-Warning Techniques for Well being Safety (CWBE) will gather and analyse neighborhood (waste)water that they are saying might be used to alert public well being groups of recent outbreaks, serving to hospitals to arrange for treating sufferers and take an infection management measures to minimise additional unfold.

“In addition to serving to forestall pandemics by detecting illness unfold early, analysis on the Centre will present higher understanding of continual, non-communicable ailments corresponding to diabetes and well being danger elements,” mentioned an announcement issued by the College of Tub.

CWBE is led by Professor Barbara Kasprzyk-Hordern, from the College’s Institute of Sustainability and Local weather Change, together with companions together with Wessex Water, the UK Well being Safety Company and departments from the UK Authorities.

Researchers will work with companions at Wessex Water to gather and analyse weekly water samples from 4 “dwelling labs” within the city catchment areas of Tub and Bristol, and the extra rural catchments of Paulton and Radstock in Somerset.

“The staff will analyse the samples for a whole bunch of hint chemical compounds in addition to pathogen markers corresponding to virus and bacterial RNA/DNA, which might act as an early-warning system for outbreaks of infectious ailments,” mentioned the assertion.

The staff may even monitor chemical compounds excreted by the physique indicating continual illness, stress or irritation, use of medicines or illicit medication, dietary habits or publicity to pesticides, hazardous chemical compounds, and family and private care merchandise.

This data will be analysed alongside prescription information, demographics and different data to offer a snapshot of the well being of the neighborhood at inhabitants degree, and the native atmosphere, so-called wastewater-based epidemiology (WBE).

Preliminary information from CWBE will present a baseline over one 12 months, after which researchers can introduce and take a look at interventions to enhance public well being.

As soon as established efficiently at Tub, the staff hopes this technique can be rolled out nationwide.

Professor Kasprzyk-Hordern, from the College of Tub’s Division of Chemistry, mentioned: “We noticed through the Covid-19 pandemic how helpful it was to get information on numbers contaminated and their location, but it surely took days to get information again from PCR exams and was very costly.

“Since entire communities contribute to wastewater, monitoring it’s a number of orders of magnitude cheaper and sooner than scientific screening.

“WBE is complete, nameless and unbiased – it may decide up asymptomatic instances, these from difficult-to-reach communities or areas missing testing infrastructure.

“By utilizing wastewater-based epidemiology we’re enabling public well being specialists to observe well being and environmental dangers shortly and effectively.”

In addition to detecting infectious illness outbreaks, the Centre additionally has analysis tasks deliberate to determine new artificial medication being utilized in communities, and to check the consequences of eating regimen and life-style decisions with continual well being circumstances.

Dr Matthew Wade, from the UK Well being Safety Company and Visiting Fellow on the College of Tub, mentioned: “The UKHSA has been working intently with Barbara’s staff on the College of Tub for a number of years to develop a nationwide wastewater monitoring system for infectious ailments and gathering public well being information.

“We’re delighted to proceed to be a part of this vital challenge and really excited to realize this milestone of launching the UK’s first pilot wastewater monitoring centre.”

Ruth Barden, Director of Environmental Options at Wessex Water and Visiting Fellow on the College of Tub’s Institute of Sustainability and Local weather Change, mentioned: “Wessex Water is worked up to be taking our longstanding partnership with the College of Tub to the following degree with this new centre.

“CWBE is taking an modern ‘One Well being’ strategy that can assist monitor the well being of the atmosphere in addition to the neighborhood, and we’re proud to be a part of this vital challenge.”

protocol concept – Ought to all despatched segments be requeued after a TCP retransmission timeout expires?


Based on RFC 793, TCP makes use of a retransmission timer per phase in its retransmission queue. Which means phase 2000 in your instance will solely be retransmit when its personal retransmission timer expires.

When ACK num 2000 is obtained, the CWND permits for 2000 excellent bytes. However at this level, there are 3000 bytes excellent, so nothing additional is shipped. TCP waits for the respective retransmission timers earlier than resending segments 2000, 3000 and 4000.

Nevertheless, in your instance situation, 4 segments are despatched directly, that means their respective retransmission timers will expire at (virtually precisely) the identical time. That will outcome within the retransmission of segments 2000 and 3000 instantly after retransmitting phase 1000.

To obviously reply the query, RFC 793’s TCP will not “wait for one more expiration of the retransmission timer” as a result of there isn’t any such factor as “the retransmission timer”. TCP will look forward to the expiration of any of the presently lively retransmission timers to retransmit the corresponding phase.

In actuality, TCP has advanced since 1981.

For instance, Quick Retransmit (RFC 2581/5681) is an exception to the above rule. After receiving three duplicate acks indicating the out-of-order reception of a phase, quick retransmit will kick in retransmitting a phase earlier than its retransmission timer expires.

TCP is byte-stream oriented, and the retransmission queue holding beforehand despatched segments is just one of some ways to implement retransmissions.

A TCP implementation would possibly as effectively do with out such a queue and generate a brand new phase ranging from the primary unacknowledged byte within the buffer. No specification requires this to be the precise copy of a beforehand despatched phase. It might have a special measurement or include {a partially} overlapping a part of the bytestream.

Introducing options like selective acknowledgments additional complicates issues.

NTT’s new AI chip totally embraces this edge-first philosophy—delivering real-time 4K video evaluation straight throughout the system, with out counting on the cloud.

A New Period for Actual-Time AI on Drones and Gadgets

With this chip put in, a drone can detect individuals or objects from as much as 150 meters (492 ft)—the authorized altitude restrict for drones in Japan. That’s a dramatic enchancment over conventional real-time AI methods, that are usually restricted to a 30-meter vary as a consequence of decrease decision or processing pace.

This development allows a bunch of latest use instances, together with:

  • Infrastructure inspections in hard-to-reach locations

  • Catastrophe response in areas with restricted connectivity

  • Agricultural monitoring throughout large fields

  • Safety and surveillance with out fixed cloud uplinks

All of that is achieved with a chip that consumes lower than 20 watts—dramatically decrease than the lots of of watts required by GPU-powered AI servers, that are impractical for cellular or battery-powered methods.

Contained in the Chip: NTT’s Proprietary AI Inference Engine
