This concept is an improvement of the existing 3-Dimmensional Spatial Projector based in 3 dimensional space rasterizing. Particularly this one was inspired by the Stars War movie and is used to project objects in 3 dimensions in a real space. Although the spectator or viewers won't be able to interact within the space of the image it would be able to walk around the Projection Volume and inspect the imaging.
The projector relies on the persistence of the vision to create the effect of a three dimensional object. It consist of a moving translucent screen that rasterizes the volume an reflect ...
The 3-terminal converter is built with HV IGBT transistors with 6,5kV blocking voltage. Transistors are controlled by fiber optic from DSP and FPGA based controller. Entire device consists of three subcircuits, which create configurable bidirectional multilevel converter, based on "DIODE CLAMPED" structure. The first converter is composed of three active rectifiers connected in series, supplied by isolation transformer. The second converter is four-level inverter and rectifier, coupled directly with 6kV AC grid. The third part is chopper as active voltage balancing system. All subcircuits are connected to a common 10kV DC link. Implemented algorithms are based on space vector ...
Micro-coil springs provide flexible electrical interconnections and allow significant movement in the x, y, and z axes to counteract the thermal expansion and dynamic forces between a microcircuit and a printed circuit board. Micro-coil springs are able to withstand harsh thermal and vibration environments significantly better than the current state of the art (see table below for performance comparisons).
NASA Value: Marshall engineers have developed a novel interconnection structure for the integrated circuit packages used in aerospace avionic designs. Micro-coil springs (MCS) replace ball or column grid arrays (BGA/CGA), preventing connection breaks due to thermal and vibration stresses.
With a market for hardware embedded system larger than 100 billion USD, the protection of these systems against various threats has become a significant issue. The vulnerability of the microsystems against side attacks has been evidenced by P. Kocher in 1998. Side-attacks rely on the recognition of the “signatures” of data transfers and of executed instructions, typically by correlation analysis. The analysis essentially involves the correlation between of the waveforms of the power (current) consumption.
The protections against this type of attack use cryptographic methods, hardware methods that try to mask the pattern of the current consumption, and a ...

Working with a considerably varied group of users, with different needs, an interface suitable to them was achieved. Our interface integrates accessible interface ideas in a single portable interface that can contribute to people with disabilities’ autonomy at home. Being a potential solution to improve the autonomy of people with impairments, the interviews have shown that home automation is not even considered as a possible solution to these people’s reality. They consider home automation a high technology solution out of their reach. It points out to the demand for researching and developing lower cost and simpler solutions.

Fire accidents in unmanned warehouses is common news. The blaze break out in ‘PATCHI ‘ warehouse, Al-Quoz, UAE in September 2013 made to inquire about cause of fire & later paved the way to suggest solution to control the fire at its earlier stage.
The fire accidents not only causes material damage but also take a toll on human lives. Sometimes, the intensity of the accident can be reduced by getting the fire under control at the earliest as possible. Our suggestion for this common issue is installation of an Advanced Firefighting System.

The goal of this system is to perform a high performance portable diagnostic ultrasound system but that's not all: The main idea is to have a stackable system up to 1024 channels, and therefore this system could use CMUT technology with great benefits:
best 3D imaging
ultra fast imaging
A 256 channels prototype is running, but it's obvious, now we could divide the size by two and increasing the performance by two also.
One of the aspect of these kind of systems is the cost, a single diagnostic system will be sell around 25k€ for a systeme with same ...

The development of textile-based wearable electronics that can be integrated into military protective clothing. A material manufacturing survey was conducted to determine the best performing and most durable materials to withstand the rigors of textile manufacturing and potential military use. Narrow woven technology was selected as one of the most promising textile manufacturing methods. The cotton will produce heat while passing current to the cloth based on the atmospheric temperature the cloth will vary heat by varying current rating using a microcontroller. In addition to this, in the battlefield if a soldier shot by the enemy it is sensed ...
With growing population and number of houses it is very difficult to measure and record power consumption in urban areas. Skyscrapers make it still difficult for manual meter reading as it is time consuming and prone to human errors. Moreover that a tiny electricmeter would be conveniently installed at top of electric poles so that bypassing meter can be permanently avoided. For this the meter must be able to be read wireless.
This project is aimed at a solution that provides easy, cost-effective and accurate Automated Metering Reading System or AMR. This system will comprise of

Most Electronic Toll Collection (ETC) systems around the world are implemented by DSRC (Dedicated Short Range Communication) technology. To propose a concept of automatic toll tax payment system and the amount transaction information send to the cell phone of the motorists through the GSM modem technology. It is an innovative technology for expressway network automatic toll collection solution. In this product, the frame composing and working flow of the system are the described data information are also easily exchanged between the motorists and toll authorities, thereby enabling a more efficient toll collection by reducing traffic and eliminating possible human ...
