International Classification:

H07J 700

US Classification:

320107, 320101, 320108

Abstract:

A self-contained, small, lightweight, portable, renewable, modular integrated power source. The power source consists of a recharging means such as solar cells that are laminated onto a rechargeable energy source such as a solid state polymer battery which in turn is laminated onto a substrate containing circuits which manage the polymer battery charging. Charging of the battery can occur via solar energy or, alternatively, via RF coupling using external RF charging equipment or a hand held generator. For added support, the integrated power source is then bonded to an applications housing or structure. This integrated power source can independently power the electronic application. It can also serve as casing or housing by taking the shape of the application enclosure.

Abstract:

An ambulatory skin temperature monitoring system. A flexible band is attachable to a patient. The flexible band also secures an electronics assembly that comprises the various electrical components that monitor and operate the ambulatory skin temperature monitoring system. At least one skin temperature sensor is positioned so that it is in contact with the patients skin when the system is attached to the patient. There is also an ambient temperature sensor positioned on the top surface of the electronics assembly housing for measuring and contrasting the ambient temperature to the skin temperature. The electronics assembly positioned within generally comprises a power source and a micro-controller. The micro-controller is coupled with the skin temperature sensor and the ambient temperature sensor. The micro-controller also includes a memory unit for storing temperature data obtained from the skin temperature sensor and the ambient temperature sensor.

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:

G06F017/60

US Classification:

705/010000

Abstract:

A real-time feedback survey system and method allowing for responses to survey questions to be input by users and received by the surveyor in real-time is provided. This result is achieved by using a media player to provide a request for feedback information to a remote responding device, the remote responding device allowing response input and incorporating a transmitter for transmitting the response to a central facility.

International Classification:

US Classification:

36518522

Abstract:

A programming control circuit programs a memory cell in accordance to a programming signal value that can be varied by a test equipment. The programming control circuit comprises a signal storage device, a signal output circuit, and a verification circuit. The signal storage device stores the programming signal value. The test equipment can be coupled to the signal storage device to write the programming signal value into the signal storage device. The signal output circuit is coupled to the signal storage device to receive the programming signal value. The signal output circuit converts the programming signal value into a programming signal and outputs the programming signal to the memory cell. The verification circuit determines whether the memory cell is successfully programmed. If the memory cell is not successfully programmed, the programming control circuit increases the programming signal value.

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.

International Classification:

G11C 1606

US Classification:

36518522

Abstract:

A voltage control circuit that programs or erases memory cells comprises an internal voltage value store, a register device selectively coupled to an external voltage value source or the internal voltage value store to receive a voltage value, a voltage output circuit coupled to the register device to receive the voltage value and to output a corresponding voltage to the memory cells, and a verify circuit determining the time to successfully program or erase the memory cells. The register device allows the memory cells to be programmed or erased with voltage values designated by the external voltage value source to determine programming and erasing characteristics of the memory cells. Voltage values producing acceptable programming and erasing characteristics are saved in the internal voltage value store.
