Lightear:

This  project is aimed at providing information regarding detection signs of ENT-related disorders by 3D imaging the ear.Conventionally,the ENT Specialist looks into the ear of the patient for check up But this method has been proven inaccurate But this method has been proven in accurate and tedious. Especially when it comes to checking a child’s ear.

This project eradicates such issues as it uses a device that looks like a headphone and is user-friendly.

SkinSpect.

This Project aims at accurate primary detection of skin cancer. However,its main purpose in india is to spread awareness about skin anatomy,skin topography and various other dermatological domains.

Cardio24

This  project is aimed at detecting cardiovascular problems at an early stage. The user wears a belt around chest.which records ECG signals more precisely as it is placed near the source.

Data is transferred wireless to an online portal accessible by both the doctor and anyone having access to the patient’s account.An algorithm then verifies any irregularity in the ECG pattern to indicate various disorders.which is an early warning sign.

DaAnt.

Its aims at Detecting dental issues like pain in gum cavity.eating patterns by recognizing facial and chewing patterns and much more.

A Health Tracker for cars:

Sensairy sloves a problem that might seem simple at a superficial level but eventually ends up causing a significant amount of trouble to millions of people.If you were looking at an elevator pitch for sensairy,it could be this it enables people to check their vehicles tyre pressure and temperature using a smartphone.

Prabu surendra ceo tymtix whose team built sens airy says that research has shown that vehicals with under inflated tyres are three times more likely to be involved in a road accident Yet people do not check the tyre pressure as often as they should one reason could be to avoid the hassle of going to a service station and waiting in queue to get the tyre pressure back up to the recommended manufacture specified levels he says.

Petrol heads could be early adopters:

If you are a car or bike enthusiast you will know how important it is to maintain the optimal tyre pressure and temperature to maximise traction.Sensairy eyes and ears so to say are a temperature and pressure sensor packed to gether.The rest of the device focuses on gathering data and comparing it to set thresholds programmed into the firmware to make the decision as to whether there is a problem that the user should know about.

The device uses a coin cell battery and works on a 2.4ghz frequency which enables a longer coverage for the device while measuring up to 150psi at almost 10000rpm.

Under normal conditions it collects data and trasfer it to the smartphone running sensairy app where the user can go through the infrmation presented on it.However if there is a situation involving say a heated up tyre or a puncture the device sends out notifications to the driver so that she or he can do what is necessary.

The best part is that what is nessary the device gathere a lot of data for example lets say there is avery small puncture on a car tyre.Users would be able to see the tyre pressre variated over a period of a few days but the app collects data and can alert vehical owners to these minor punctures that are not obvious are to them explains surendrs the product also lets you track multiple vehicles simultaneously.

Essentially what they have done here is data visualisition and analytics on tyre and pressure data it is somewhere similar to what the billion dollar company jawbore has famously done with their up series of bands.

Another element that will be inclded in future models is shock detection an accelerometer that senses shocks caused due to bumps and road problems will help users better estimated and even alongate the life of the tyre by making sure they are taking care by keeping the tyre properly inflated.It will also help them properly maintain the tyre pressure during dry and rainy mounths when it is recommended to slightly decrese or increses the pressure to maximise performance.

The accelerometer can also help users judge the performance of the suspension setup.If they have spent a bomb on getting koni bilstein or tien shocks for their cars they can use this app to follow up on the installation to track how shock data changes for the car while rnning on the same strip before and after suspension upgrade.

What he is more excited about is the potential to use the data flowing in form a large number of sensairy enabled vechicles to judge the road conditions of diffrent type.This idea has the potential to change the way we think about judging rad quality in cities.

Using Wearable Devices:

The rising rate of pollution,tradiness and a couple of other issues has led to numerous health issues,in particular,cardic issues,asthma and denatal issues,which are posting to be life threating and life deteriorating.Besides,we often encouter issues like imbalance in stress levels,emotional outbursts and physiological and emotional breakdown.So the trend is moving towards the creation of healthcare products to ascertain symptoms and preliminary signs of any disease or disorder.

One of the major steps taken in this regard is by Massachussects institute of technology media lab’s REDx programme,where students and working professionals devote their time and effort towards building prototypes in the healthcare sector. The main aim is to deploy these devices in india,hence the projects worked on by the teams are customised according to the problems faced in india.

Every year MIT Redx camps take place in Mumbai. Hyderabad and nashik.usually in the month of january .MIT media lab camera culture groupheaded ,Getting inputs from various doctors,hospitals and internet sources has helped the teams to set goals for their respective projects and work in this regard.A brief of the prototypes being built is outlined in this article.

Design Challenges:

Tyres on any vehicle face some very extreme conditions,so placing your components inside these is a technically challenging aspect of their design in fact some people say that this is exactly the place where an electronic system should not be installed.

one of our earliest problems was that we were unable to fit the sensing system to properly measure pressure in feasible way.We could get it in through a laborious process,but it would not make sense to do it from a customer standpoint or even allow us to do a proper demonstration.So while we were trying to figure this out one of our sensor vendors chief research snd development person invited me over and showed the facilities that they have it was during this tour that i discovered tha kind of test setup we actually needed to build the product we had in mind.

Another problem that they had was that the enclosure was built out of aluminium now aluminium has this problem that it absorbs all signals due to it acting like a faradays cage.When they placed the sensor inside it no signals could make their way out of the device.the team was very disappointed when this happed says he.While we were trying to figure out how to slove this problem.We come upon a material that had the characteristics of ABS pkastic and did not absorb the signals that our device needed to transmit.

Battery life is another area where they did some tuning and revisions to come up with the perfect sauce.For instance they designed a rabge extender in the device that has the consequence of reducing battery life.So that it only activates the extender when it is really needed.like in the case of a puncture where the car needs to alert the user as early as possible.

Another event that deactivates the range extender is when the car is moving so they used the accelerator to figure out if the car was moving and deactivate it if it was.It also changes the frequency of testing depending on different times of the day or usage history.They eventually left the range extender out of the first version of the product to control cst but there is a good chance that it would show up in a future version.

Testing is one area where i am facing a challenge.Normal tyre can only handle up to 50psi of pressure-nut i needed to test the sensor at 150psi or make sure it works in heavy duty tyres.I also needed to test the sensor while running  at 10000rpm so what i dis was to get access to a dynamo meter it was pretty expensive in our case since need to constantly try and improve the system.We are now trying to the set the system.We are now trying to might go for  a gyroscope intend of an accelerator for suspension and wheel aligment issues in figure product.

How it stacks up to the alternatives:

There are a lot of alternative tyre pressure monitoring systems in the market where they connect a gadget on the tyre and a small display is mounted on the dashboard through which you can see data on tyre pressure in high end vehicles stock infotainment system too.But these solutions require vehicle owners to be inside their vehicles to check tyre pressure which is not a requirement for sensairy.

One unique challenge that none of the existing solutions for non luxury vehicles solve is that these do not alert you about a tyre puncture or critically low tyre pressure until you are near the car or turn on the ignition.The problem here is that it makes the situation ripe for there unfortunate day where you are greeted by a flat tyre while hurrying to your office in a jacket and trousers.

A more significant benefits is for fleet management companies that have long trailers or road trains with a large number of tyres at complex locations.Some might have multiaxle tyres where there are eight tyres at one point in a bus.Then there are lorries with tyres imagine the pain of installing a normal TPMS.
