International Classification:

H01L021/66

US Classification:

438 14, 438 15, 438 18, 257 48, 257777, 257778, 257782, 257784

Abstract:

A semiconductor die adapter assembly includes a semiconductor die cut from a wafer, the die having an active surface including bond pads. A die adapter, also having bond pads, is bonded to the semiconductor die. Die-to-adapter connectors electrically connect the die bond pads to the adapter bond pads. Finally, adapter-to-substrate connectors electrically connect the adapter bond pads to a device substrate. Having bond pads on the die adapter eliminates the need to break and remake the electrical connections to the original bond pads on the die during burn-in testing of the die.

International Classification:

US Classification:

436106, 436107, 436110, 436111, 436156, 436172

Abstract:

An explosive detector that utilizes an array of molecularly imprinted polymer (MIP) coated, bifurcated fiber optic cables to form an image of a target molecule source. Individual sensor fiber assemblies, each with a calibrated airflow, are used to expose the fibers to the target molecule. The detector energizes a dedicated excitation light source for each fiber, while simultaneously reading and processing the intensity of the resulting fluorescence that is indicative of the concentration of the target molecule. Processing electronics precisely controls the excitation current, and measures the detected signal from each narrow band pass filter and photodiode. A computer with display processes the data to form an image of the target molecule source that can be used to identify the source even when low level contamination of the same molecule is present. The detector can be used to detect multiple and/or non-explosive targets by varying the MIP coating.

International Classification:

G06F 19/00
H02J 7/00

US Classification:

320119, 702 63

Abstract:

A method of equalizing charge states of individual cells in a battery includes measuring a previous cell voltage for each cell, measuring a previous shunt current for each cell, calculating, based on the previous cell voltage and the previous shunt current, an adjusted cell voltage for each cell, determining a lowest adjusted cell voltage from among the calculated adjusted cell voltages, and calculating a new shunt current for each cell.

H02K 500
A43B 702

US Classification:

320107

Abstract:

The invention comprises a means for generating energy while walking or running for storage in a rechargeable battery. One embodiment uses lever arm movement in the heel of a shoe resulting from normal walking or running to generate energy from a built-in generator. The linear or rotational motion of the lever arm engages the circular gear assembly and turns the generator/motor/turbine, thus generating power. The second embodiment uses fluid reservoirs embedded in the shoes. Pressure changes resulting from normal walking or running moves the fluid through a narrow channel connecting two reservoirs, thus generating power by rotating a flywheel and an attached motor/generator/turbine in the middle of the channel. Secondary (rechargeable) batteries are incorporated into the invention either in an integrated form or as an add-on design. Additional features include a digital diagnostic data output, which would serves as a "fuel gauge" for the secondary batteries, and a smart charging circuit that efficiently controls battery charging from a generator output that varies with step rate and force.
