Evolutive Software Design Paradigm (ESDP) is a paradigm of software creation backed up by the Artificial Intelligence field. What is it about this idea? It is simple, software that is capable to learn with user's experience using it ("learn" as in enhancing functions by itself, or even create new ones). This software must count with an AI engine that lets the software to grow in a certain way the user wants. The software must be capable of analyzing the situation (the "needs") and should be capable of writing the code for providing the solution, without vendor's intervention. This makes this kind of software cost-effective to use, because the user wouldn't have much need of querying the vendor about a ...

The Finite-Difference Time-Domain (FDTD) method is currently a popular method of performing electromagnetic computation. The FDTD algorithm's relative simplicity and versatility make it a useful tool for simulation, but the benefits are partially offset by the memory and computational power demands. These demands limit the algorithm's practical usability, and are usually implemented on high performance workstations. The FDTD computational method involves a series of simple calculations over the field of interest, iterated over many time cycles. Using a single threaded processing model, this is usually implemented very inefficiently as a series of nested "for" loops.

I propose that this algorithm be accelerated in hardware using the inherently parallel nature of a field programmable gate array (FPGA) device. If code ...

We must remove some of the circuits in the Television, the power supply, tuner, audio, speakers, input/output components, and the IR receiver. It is no longer a TV, it is a display device. Now we will build the basic tower. It will be approximately 8 inches deep and 8 inches wide. Height will be determined by which model the consumer wants, 2 slots, 3 slots, etc. In the bottom of this tower will be an universal, switched mode power supply. It will operate at all known frequencies and line voltages and will work in all countries. Above the power supply will be at least 2 openings/slots. These slots will have a plug in connector in the back. This tower ...

Many of today micro-controllers circuit were developed for battery operation.

It is a hard task to debug the product for power consumption.

My idea is to develop a low cost power debugger - an electronic measuring system (software & hardware),a combination of a current sense power meter and analyzing software who can pin point the current consumption element in the design - whether it is hardware (static current) or software (who activate a hardware element).

The power debugger will use a a small micro controller as a data logger/sampler,and PC computer as a process & display element.

The PC software will display a real time graph of the HUT (hardware under test)power consumption including peak power,average ...

My main aim was to have a project that has an equal involvement of hardware and software. Also we decided to take up a project that is visually appealing and ended up concentrating on the latest display technologies. Finally we decided to do the project on persistence of vision (POV) displays. The display will be able to show text messages, numbers, patterns, etc.

Principle: POV stands for persistence of vision. It is a term that has been adopted while considering devices that rely on the eye's tendency to continue to "see" an image for a short time after it has disappeared. Persistence of vision is the phenomenon of the eye by which an after image is thought to persist ...

Almost all communication systems become inoperable during and after natural calamities like earthquakes, floods, tsunamis, cyclones etc. Often it takes months to at least restore a fraction of it. If they are restored as soon as possible many lives can be saved and losses reduced. In the present scenario, the only reliable communication equipment used for search and resue is HAM radio. But the present communication bandwidth cannot be handled by HAM radio alone. Thats why we designed such a system.

The system we designed is a High Altitude Platform (preferably a tethered helium balloon) based emergency communication system which can be quickly deployed as soon as the disaster strikes. The system will be based on packet data communication ...

Hologram Phone (HPhone) is a communication device that projects real-time 3-D images between users.

Overview:
The HPhone utilizes advanced laser and satellite technologies which results in an exciting future of futuristic telecommunications. "Live," absolutely precise, three-dimensional 3-D images of users are move and react with one another. Special glasses are NOT needed in that the holographic image is clearly projected in the room with the user.

Benefits:
The biggest benefit of using the Hologram Phone is the ability to "humanize" phone conversations with instant face-to-face conversations. Users have the benefit of seeing and almost feeling the presence of others. Additional benefits include video conferencing, multiple user conference calls, real-time examination of patients, family, business, emergency communication.

Markets: ...

When people get a driver's license, many of them have the restriction on the back of the license saying that they need corrective lenses in order for them to drive, but most people including myself forget to always carry them with them at all times. So I was thinking, what if the driver side of the windshield had a transparent filament that would act as a lens that would be placed on the driver side windshield and would transform that part of the windshield into corrective "eye wear." I bet that it would most likely reduce the amount of fender benders on streets, which is due to poor judgement on distance from the car in front to your own ...

Robotic vision has been forecast for decades, but in reality machine vision does not yet work very well. I suggest using a new approach to image analysis, similar to what evolution has done for mammals. If machines and robots could see the way mammals do, then it would be much safer to work with them, have them perform work that is too dangerous for humans, and in general augment human vision with machine vision. Elder care robots, automotive guidance systems, drug discovery, fMRI image analysis, even air traffic control would benefit very substantially from machine vision that is real-time capable and fully deterministic. One such system is being developed at Parimics, and the simulation models show that our system ...

Typical temperature compensation techniques for wireless communications add ~$1 per oscillator, reduces battery life and reliability. Based on current experiments and patents granted, we can establish tighter frequency control while removing the added cost and complexity in the circuitry commonly used in cellular and other wireless applications. By adjusting the quarts cut away from the AT angle area, we adjust the effective stiffness of the hemihedral crystalline structure so that its third order temperature coefficent is lower than the the industry standard AT cut. Prior efforts in this area led by Seico with the GT cut have produced technical performance but are not inherently mass producible due to the nature of the acoustic wave which is an extensional mode ...
