The College Park Industries iPecs® (Intelligent Prosthetic Endo-Skeletal Component System) is a medical research device which will provide researchers a tool to accurately measure human locomotion or gait parameters on users of lower limb prostheses. The iPecs measures forces and torsion-moments which can then be wirelessly transmitted in real time, to a PC interface. This wireless capability of the iPecs will, for the first time, allow environmentally unencumbered research to be conducted outside of the laboratory setting providing insight into what a prosthesis user experiences on a daily basis. This device is a measurement tool which will initially provide researchers, and later clinicians, with the first commercially available method to objectively quantify the full range of real world kinematic ...

The backlight in laptops consumes a lot of power and is often not bright enough to compete with sunlight when viewed outdoors.

When inside, the traditional backlight is used. However, when used outside, the top light-cylinder guide is used to gather sunlight and funnel that into the light guide, creating tremendous backlight illumination.

This invention makes your laptop usable outdoors and saves precious battery power ...

Space-borne communications platforms are restrictive on weight and mass as these are directly proportional to launch costs. As a result, the antennas are usually integrated on the platform as space available on an existing launch vehicle. The usual suspects are foldable high-gain dishes or extendable booms for C-band, VHF, UHF. What I am presenting a more natural design and approach space communications.

Usual analysis of dishes involves, using tools like GRASP or other MoM code which achieve a highly tuned product but parabolic antennas are highly susceptible to manufacturing tolerances which increase exponentially as the transmit/receive frequency increase linearly this is effect directly controls the cost function. This need not be the case. There are many objects on the ...

Problem:
Counterfeit ICs used in critical systems are a threat to safety and security. It is difficult to identify counterfeit ICs quickly or accurately.

Solution:
Using NDT Ultrasonic Resonance Testing methods, characteristic ultrasonic spectra signatures would be made of known 'good' ICs, and a go/no-go criteria range would be developed by testing a number of 'good' parts. Suspect ICs would be tested and compared against testing criteria. Minor variations in die size, packaging materials, bond wiring, internal lead wiring, and other characteristics would show up as peaks, dips, and shifts in characteristic spectra. Since known 'good' manufacturers would use consistent materials and design, ICs of the same part number should match a small range of characteristic ultrasonic spectra. Counterfeit ...

The Mithras Concentrator is a lightweight, rapidly deployable 100W solar power device, utilizing concentrated photovoltaic technology. CPV introduces a low-cost option to solar power generation, using reflective surfaces and a Fresnel lens to consolidate sunlight from a large area into a tighter beam. This reduces the cost of the final product, decreasing the number of PV cells necessary to capture a given amount of light energy, while producing a consistent voltage output and making more efficient use of space.

Solar cell performance is inversely proportional to temperature, and falls off rapidly after a certain threshold (around 110 degrees C). Black PV cells experience high temperatures because they absorb infrared and ultraviolet light. Our PV harnesses energy from the visible ...

Aircraft/micro-satellites/wearable canteen or backpack computers. All require reduced size & weight, and functional adaptations. The Nano-Frame concept requires the chip industry move forward to the System-On-a-Chip computing slices. This also provides the mechanism and future home for the evolutionary direction we are already heading. Reduced costs, weight, manufacturing efficiency; It all comes together here.

This design comprises SOC functional slices inserted into ceramic rail backplanes. Red for the power bus and white for data communications I/O bus.

This example assumes the black (ops) slice is a software defined radio - intelligence gathering DSP; white a solid state RAM preloaded with OS and mission parameters; blue DSP for k-v-m human interface visualization; and gold the general CPU & controller.

Ceramic ...

Nanotechnology deals with the study of nano sized particles. With the study of nano size particles, devices, and composites, we will find ways to make stronger materials, detect diseases in the bloodstream, build extremely tiny machines, generate light and energy and purify water. The most fascinating application of Nanotechnology is to make Nano sized switches to store information.

The memory needs of the contemporary world have increased dramatically. Fulfilling these needs, a constant work to improve the capacities of today’s memory devices is in progress. The maximum available semiconductor RAM in common use is of 1GB. Even this could not fill the growing memory desire of today’s users. As a result a nonvolatile, fast and vast RAM has been built ...

LED replacements for four foot T8 fluorescent lamps have a energy saving of about 35%. By adding a wireless or power line networking electronics directly into the tube additional energy savings can be accomplished, via dimming or selectively turning off individual tubes per fixture. Upwards of 85% total energy savings can be accomplished using these technique. Considering the fact that 20% of the electrical energy generated in the USA is for lighting, this is a significant energy saving.

Area lighting can be selectively tuned for corridors (dimmed), office cubicles (Low/Med/High brightness), or open areas. Detection of occupancy, directly by the tube, can turn off lights when cubicles are exited, and immediately turned back on upon re-entry in a soft ...

RF power amplifiers (PAs) operation most efficiently at near full power and most modulation schemes require an amplifier to be over designed to handle the cresting factor (average to peak power) which can be 12 dB or higher. With digital coding, signals are broken into phase and magnitude using QAM, 8PSK, 16PSK and other methodology. The only limitation in going to higher levels of coding is the stability of the reference used to generate the clock and frequency base. My remedy to this situation would be to have CW frequency triplets with the first frequency in the triplet carry a reference phase for the other two carriers. The second carrier would have the phase information and the third carrier ...

The nearly omnipresent wireline telephone system has been trying to get Broadband digital information to the greatest number of users with some form of Digital Subscriber Line (DSL) signals called Discrete Multi Tone (DMT). DSL-DMT is self limiting from intrinsic co-channel interference which gets worse as more customers try to get service through the same bundle. As a result millions of users can’t get decent access to email, the Internet for knowledge and information, for video and voice over IP, for telecommuting, for telemedicine, for distance learning and for fun. The conventional industry has been pushing the providers to use very expensive hybrids of fiber optics with more exotic DSL versions to get digital signals closer to the users. ...
