Though we have many other biometric solutions, fingerprint identification system is widely used for many reasons. Compared to other biometric techniques, the advantages of fingerprint-based identification are as detailed below:

Uniqueness of the fingerprint - the minutiae details of individual ridges and furrows are permanent and unchanging.

The fingerprint is easily captured using low cost fingerprint scanner.

In the case of noisy images, enhancement of curved structures are required. For that purpose we introduce CNN filters that locally adapt their shape to the direction of flow. These CNN filters enable the choice of filter parameters that increase the smoothing power without creating artifacts in the enhanced image.

In this project CNN filters are applied to the curved ridge ...

The Health Watch is different from a fitness watch which not only helps to burn calories or reads the heart beat; it is also one step ahead in maintaining a balanced diet for people who often miss their proper nutrients in their food in the day to day busy life. This watch is built with all types of sensors which monitor the quantity of water a person is taking by evaluating the blood sample. Eventually it alerts the person if he is in short of water intake. It monitors the consumption of food by respective person and gives the nutritional comparative statistics at the end of the day daily. It tracks the pulse rate and warns if there is ...

Hearo is the world's only Internet Of Sound system. With Hearo any object in your home can be a digital controller. It works like this:

The sound of hitting my tea cup with a spoon make Spotify skip to the next song in my playlist. And the sound of the glass bowl I got from my aunt turns on or off the light a room.

Hearo is a device you put on your wall or hide it if you don’t want to see it. And then you teach Hearo to identify certain sounds from certain objects with the app. But the intelligence is in the device, so Hearo doesn’t record the sounds from your home or store it online, ...

For nearly a century Building management HVAC systems have relied on thermometric feedback to control temperature in buildings and although in recent years smart thermostats have been introduced the control remains temperature sensor based. The intelligence of the latest generation thermostats offers occupant habit learning, Internet app control and algorithms for better control. Although increased management has helped reduce fuel consumption, temperature feedback has limitations and cannot anticipate changes in outside conditions similarly to what a Heat flux sensor based thermostat could deliver. A heat flux sensor can monitor outdoor conditions by monitoring the levels of heat flow inward or outward of the building through the walls. Changing conditions can include rapid changes in temperature, heat loading from the ...

This invention relates to cooling devices which maintain the correct operating temperature for computer processors. The devices use the relatively new FASTT technology to enable high flux cooling of processor chips without the use of liquids.

Heat pipes have provided a relatively simple method of increasing the cooling flux from computer processors, but suffer from large cumbersome pipe/finning sections to achieve dissipation to ambient air. Liquid cooling systems allow more flexible positioning of the large output, air blast cooled section, but long term integrity of pipework jointing and coolant maintenance can be issues. FASTT technology offers an alternative cooling scheme which does not rely on the use of liquids, and in which the heat transfer medium also serves ...

LiquidCool Solutions developed the LCS Edge, a purpose-built, high performance-computing appliance that revolutionizes the Internet of Things (IoT).

The issue with IoT is the massive amounts of data overloading today’s cloud models. Cloud computing is not designed to handle the volume, variety, and velocity of data IoT generates and the problem will only get worse as more IoT devices are deployed. Moving data from sensors to the cloud for analysis requires massive amounts of bandwidth, and networks already are congested. Pipelines are so crowded the opportunity to act on information may be gone by the time it reaches the cloud for processing. If IoT continues to grow at its current pace the entire system will collapse under its own ...

One of the goals in modern power supply design is to minimize the losses respectively the heat dissipation. The biggest source of power loss is still the electronic switches - transistors and diodes, and while the transistors are experiencing progressive improvements of their properties, the diodes still have limitations, imposed by their structure. To avoid power losses in diodes they are often replaced with MOSFET transistors, as is the case with the synchronous rectifiers. The proposed design offers a simplified solution for improving the efficiency in the bridge rectifiers by replacing the diodes with N-channel MOSFET transistors. The modified scheme is shown in Fig. 1.

The gate voltage for T1 and T2 is provided by the charge accumulated in ...

The ability to construct multiple-perspective images of natural or synthesized scenes is growing rapidly driven by advances in computational power and image capture technology. In principle these images provide the input data for virtual reality hologram-like displays that produce light fields that approximate the light from a real object, with natural perspective change with observer viewpoint and stereoscopic perception without viewing aids such as special glasses. In practice display technology has lagged image production technology. Head mounted virtual reality displays allow individuals access to this rich visual world, while larger hologram-like displays based on flat panel technology have limitations in brightness, resolution and field of view. The proposed large display technology is based on projection technology and allows higher ...

Internet of Things (IOT) is an evolving technology in Mobile Computing, resembling the Distributed Network Environment, where physical objects are embedded with electronics, software, sensors and connectivity to stay connected over the Internet and communicate with each other. The IOT Objects on the Internet are capable of identifying each other with their Domain name, Network Address or through the Embedded Computing System which runs on existing Network Infrastructure. IOT goes beyond Machine-to-Machine (M2M) communication and covers several Protocols, domains and networks, enabling advanced applications like Smart Grid. The application usage of IOT are many and Home Automation is one of them providing automatic control of home appliances & security, remotely. In order to provide Security and Automation System, Wireless ...

We augment typical, low-cost plastic traps for many insect pests with the necessary optoelectronic sensors to sense the entrance of the trap to detect, time-stamp, GPS tag, and –in relevant cases- identify the species of the incoming insect from their wingbeat. For every important crop pest, there are monitoring protocols to be followed to decide when to initiate a treatment procedure before a serious infestation occurs. Monitoring protocols are mainly based on specifically designed insect traps. Traditional insect monitoring suffers in that the scope of such monitoring: is curtailed by its cost, requires intensive labour, is time consuming, an expert is often needed for sufficient accuracy and can sometimes raise safety issues for humans. These disadvantages reduce the extent ...
