DIETSENSOR

DIETSENSOR

Manually logging in meals can be exaspirating, we know. That’s why we worked hard to develop this sleek, snappy, little app just for you. By scanning your food, it’ll take 10 times fewer clicks to log a food than with other manual input methods.

Do you need better control of your nutrition? Our app reads the spectrometric scans from your SciO scanner and provides accurate analysis of your homogeneous food or beverage. Spectrometry is the process we use to identify the chemical makeup of your food. This even takes into account specific cooking and additive ingredients, like cooking oil. We believe that if nutrition tracking isn’t accurate, it isn’t helpful.

DietSensor gives accurate results with any homogeneous food, even with homemade dishes and beverages that do not have a nutritional label. So you can stay balanced, even when it’s home cooked.


For those times when you need to input non-homogeneous foods, you’ll have access to our extensive, ever-expanding food database with over 600,000 food items from 50 countries (in 19 languages!) with ultrafast bar-code scanning.

DietSensor innovative progression chart gives you comprehensive information on carbs, fat protein, calories, and alcohol levels to provide customized nutrition goals. Stay on target by getting tailored-to-YOU feedback on the quantity and quality of your food. Recurring diet setbacks. Weight fluctuations. Low hydration levels. DietSensor helps you recognize and understand your own habit patterns and advises you accordingly.

DietSensor is in partnership with Consumer physics, creators of the first, pocket, wifi-connected molecular sensor. SCiO uses something called near infrared spectroscopy to determine the chemical makeup of food and drink. Each type of molecule in a food vibrates in its own unique way, and these vibrations interact with light to create a unique, optical signature. In brief, spectrometers analyze what is in a substance based on how its molecules interact with light

. The SCiO shines a light on the food or beverage of your choice when you click a button. Then, a tiny optical sensor (the spectrometer) collects the light reflected from the food sample. It breaks the reflected light down to its spectrum, or the array of varying wavelengths.

DietSensor builds spectrometric models that translate the resulted information into something really useful – a calorie count and the percentage of carbohydrates, fat, and protein contained in your food. This is all quickly sent and clearly displayed on the DietSensor app on your smartphone.

We are ever-expanding our database to give you the widest range of food and drink possible, so you can always get a clear readout, even for those healthy muffins you just pulled out of the oven.

Paper Battery

Paper Battery

A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nano-tube s with a conventional sheet of cellulose-based paper. A paper battery acts as both a high-energy battery and super capacitor , combining two components that are separate in traditional electronics. This combination allows the battery to provide both long-term, steady power production and bursts of energy. Non-toxic, flexible paper batteries have the potential to power the next generation of electronics, medical devices and hybrid vehicles, allowing for radical new designs and medical technologies.

It is basically a device which can act both as a capacitor and as a battery. It is a flexible, light weight device made up of carbon nano tubes emboldened on paper (cellulose). It is basically formed by combination of cellulose with carbon nano-tubes. It consists of infusion of carbon nano-tubes with paper consisting of an ionic liquid as an electrolyte.

Paper battery can actually prove beneficial for applications where portability and size is the main requirement. Modern day electronic equipments like smart cards, digital watches facilitate the requirement of thin batteries which are long lasting and non toxic. Wearable Computers – One of the latest real time examples of wearable computers is Google Glass. 

It actually is a normal spectacle with an optical head mounted display and Glass is a computer in the form of a pair of eyeglasses and includes an optical head-mounted display which allows the user to use a smart phone. It can also be used for low power devices like calculators, wrist watches and wireless communication devices like mouse, Bluetooth headphones, keypads etc.

Paper batteries may be folded, cut or otherwise shaped for different applications without any loss of integrity or efficiency . Cutting one in half halves its energy production. Stacking them multiplies power output. Early prototypes of the device are able to produce 2.5 volt s of electricity from a sample the size of a postage stamp.

The devices are formed by combining cellulose with an infusion of aligned carbon nano-tubes that are each approximately one millionth of a centimeter thick. The carbon is what gives the batteries their black color. These tiny filaments act like the electrode s found in a traditional battery, conducting electricity when the paper comes into contact with an ionic liquid solution. Ionic liquids contain no water, which means that there is nothing to freeze or evaporate in extreme environmental conditions. As a result, paper batteries can function between -75 and 150 degrees Celsius.

One method of manufacture, developed by scientists at Rensselaer Polytechnic Institute and MIT, begins with growing the nano-tubes on a silicon substrate and then impregnating the gaps in the matrix with cellulose. Once the matrix has dried, the material can be peeled off of the substrate, exposing one end of the carbon nano-tubes to act as an electrode . When two sheets are combined, with the cellulose sides facing inwards, a super-capacitor is formed that can be activated by the addition of the ionic liquid. This liquid acts as an electrolyte and may include salt-laden solutions like human blood, sweat or urine. The high cellulose content (over 90%) and lack of toxic chemicals in paper batteries makes the device both bio compatible and environmentally friendly, especially when compared to the traditional lithium ion battery used in many present-day electronic devices and laptops.

As a result of the potentially transformative applications in electronics, aerospace, hybrid vehicles and medical science, however, numerous companies and organizations are pursuing the development of paper batteries.Specialized paper batteries could act as power sources for any number of devices implanted in humans and animals, including RFID tags, cosmetics, drug-delivery systems and pacemakers. A capacitor introduced into an organism could be implanted fully dry and then be gradually exposed to bodily fluids over time to generate voltage.

Working:

Internal operation of paper batteries is similar to that of conventional batteries with each battery generating about 1.5V. If one can recall traditional batteries work in the manner where positive charged particles called ions and negative charged particles called electrons move between positive electrodes called anode and negative electrode called cathode.

Current flows as electrons flow from anode to the cathode through the conductor, since the electrolyte is an insulator and doesn’t provide a free path for electrons to travel.

Similarly in some paper batteries, carbon nanotubes act as cathode, the metal is the anode and paper is the separator. Chemical reaction between metal and electrolyte results in production of ions whereas chemical reaction between carbon and electrolyte results in production of electrons. These electrons flow from the cathode to the anode through the external circuit.

Given below are three ways to create paper batteries:

1. The first method involves fabricating zinc and manganese dioxide based cathode and anode. The batteries are printed onto paper using standard silkscreen printing press. This paper is infused with aligned carbon nano-tubes which are used as electrode. This paper is dipped in a solution of ionic liquid which acts as the electrolyte.

2. The second method is a bit complex and involves growing nano-tubes on a silicon substrate. The gaps in the matrix are then filled with cellulose and once the matrix is dried, the combination of cellulose and nano-tubes is peeled off. Thus sheets of paper consisting of layers of carbon nano-tubes are created. Two such sheets are combined together to form a super capacitor with a ionic liquid like human blood, sweat or urine being used an electrolyte.

3. The third is a simple method and can be constructed in a laboratory. It involves spreading a specially formulated ink of carbon nano tubes over a rectangular sheet of paper coated with an ionic solution. A thin film of lithium is then laminated on the other side of the paper. Aluminium rods are then connected to carry current between the two electrodes.

Six Important reasons How Paper Batteries useful:

1.Paper batteries have long lasting time. 

2.They are non toxic as they do not involve harmful chemical reactions. 

3.They are flexible and can be folded or cut without any effect on their efficiency. This is because of the fact that they are made up of materials like cellulose and carbon nano-tubes which have high tensile strength.

4.They are disposable as they are made up of cellulose which is bio degradable and non toxic. They can be used in harsh climate conditions like heat and cold. This is because the electrolyte does not involve water which makes the battery operate in the range of -73 to 149 degree Celsius.

5.They utilize carbon nano-tubes, which are one of the most highly efficient conductors of electricity.

Sony HMZ-T2 Personal 3D Viewer

World's first wearable personal 3D viewer

Sony launched the so called world’s first wearable 3D TV in India for Rs.69,900. The HMZ-T2 personal 3D viewer is a head-mounting device which has HD 2D and 3D personal display with win OLED screens.

The last among the many gadgets released by Sony on October 11, 2012 is the personal 3D viewer. This device is named as 3D Viewer HMZ-T2 and Sony has priced it at Rs.69,990. This sci-fi looking gadget is already available for pre-order at Sony Stores and they will be out during the Diwali season.

The Personal 3D viewer comes equipped with a HDMIU cable which can be connected to any device that has an HDMI port. Sony has made some changes as well from their earlier version; HMZ-T1. The built in ear buds have made way from regular 3.5 mm audio out jack. This change makes it easier for the user.

Once put on, the user looks like he walked right out of a science fiction movie. These glasses are not at all a disappointment when it comes with 3D images and brilliant sound quality. The 3D images that one views with this camera are not disappointing at all. The two individual OLED screens in the glasses allow the user to experience smooth transition between 2D and 3D content. The sound quality through these glasses is also quite impressive. But there is a drawback with the headphoens; since it is tiny the user must make sure he is in a very quiet environment.

The Sony HMZ-T2 Personal 3D Viewer is the second iteration of what Sony had initially created as a concept product. Designed as a way of looking into the future of home entertainment the device is Sony's answer to the awkward truth that 3D in the home still isn't perfect.Using two tiny OLED screens, the HMZ-T2 is able to create a 'perfect' 3D image without any of the eye-based confusion that can still take place using passive or active 3D technology.

These are claims that shouldn't be taken lightly, not only does the HMZ-T2 cost as much as a high-end TV, but it also limits viewing in that only one person can see the image. Of course, if that image happens to appear the size of an IMAX screen then things begin to make sense.

SIZE AND BUILD

With an almost identical look and feel to the original Personal 3D Viewer the HMZ-T2 has clearly taken its design cues from the world of Tron looking about as futuristic as you can get. With a plastic body and rubber headband it's not too heavy either coming in at a reasonable 330g. All the controls are sensibly arranged along the bottom while the now interchangeable headphone jack has been bafflingly placed inside the eye cavities resulting in a tangle of wires before you've even turned it on.

Where the HMZ-T2 fails is in how you actually wear it. Available with a series of rubber inserts that help to block outside light out, one wonders why these actually aren't a permanent fixture. Instead you have to individually pop each part of the 'blinkers' resulting in something that is less than stable adding to the overall feeling that perhaps you're still using a prototype.

SETUP

Taking this approach resulted in a completely painless setup. There's a box for HDMI input/output and power, the HMZ-T2 then uses a separate cable, which runs to the headset itself.

The wire is more than long enough for pretty much any living room. Because it's a single HDMI you can plug in almost any input from a Blu-ray player, your Sky HD box, Xbox 360 or Sony PS3 with the only downside being that it is just a single input so you will have to disconnect everytime you want to switch between formats.

PICTURE QUALITY

The headsets features two small OLED displays each of which has a resolution of 1,280 x 720 pixels. Yes you read correctly, that's NOT Full-HD. Does it matter? The only way to answer that question is by breaking it into two parts; gaming and films. Treat the HMZ-T2 as a gaming device and you'll be treated to a completely original gaming experience, well until the Oculus Rift is finally released.

With both the Xbox 360 and the PS3 maxing out at 720p the images you see are not only huge (The T2 creates a virtual screen size of 750-inches) but also clear. Fast response times along with the virtual 5,1 surround sound both contribute to create an immersive gaming experience that you simply won't find anywhere else. We spent a weekend playing Bioshock Infinite and felt a palpable sense of disappointment when we reverted back to a conventional TV.

Watching regular 2D films are where the chinks begin to show. Because the output is only 720p and the viewer has been designed for 3D viewing it immediately becomes clear that what you're seeing isn't the full Blu-ray experience. Instead fast moving images can become blurry and picture quality is noticeably reduced. The rubber attachments are an annoying design flaw while the fact that it's not Full-HD is regrettable. Add to that a price tag that could make you weep and what you have is a brilliantly engineered, but still not fully practical piece of the future.
