摘要:
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.

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.
摘要:
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.

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. Data from the system can be downloaded to a remote computing device where software can plot the data in a desired format for analysis by medical personnel.

A microprocessor-based charge control architecture which provides individual battery cell charge control in order to insure an equality of charge among all cells in a rechargeable battery cell array during a single charge cycle. The array is arranged in parallel strings with an identical number of cells in series in each string. The microprocessor controls the amount of charge current in each battery cell via a shunt element for each battery cell, and adjusts the shunt element to bypass a portion of the string current for each battery cell. The invention also permits charge control algorithms to be conveniently updated, provides individual cell coulometry, and autonomously monitors and corrects conditions which can result in battery failure. Any type of rechargeable battery cell and array size can be accommodated. The array size can be set to accommodate the specific voltage and load current requirements of each application.

A self-contained, small, lightweight, portable, renewable, modular integrated power source. The power source consists of solar cells that are laminated onto 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.

A method and system are disclosed for memory cell soft program and soft program verify, to adjust, or correct the threshold voltage between a target minimum and maximum, which may be employed in association with a dual bit memory cell architecture. The method includes applying one reference voltage signal to the over erased core cell, and a different reference voltage signal to the reference cell, comparing the two currents produced by each, selectively verifying proper soft programming of one or more bits of the cell, determining that the dual bit memory cell is properly soft programmed. The method may also comprise selectively re-verifying proper soft programming of the cells after selectively soft programming at least one or more bits of the cell.
摘要:
A block decoder includes a p-well. A low voltage source is coupled to the p-well for asserting a body bias voltage to the p-well. An n-type word line pass transistor is positioned within the p-well and is coupled to a word line for passing programming voltages to the word line. A high voltage source is coupled to pass circuitry configured to assert a voltage on a gate of the pass transistor. The low voltage source is configured to apply a voltage of approximately 10 volts or more to the p-well during programming, thus reducing the voltage between the source and body region (and thus the threshold voltage as well) of NMOS transistors disposed within the p-well. Therefore, the amount of voltage needed to be applied to the pass transistors is reduced. Furthermore, the pass circuitry can work for lower supply voltages since the supply voltage is limited by the threshold voltage of the n-type transistors within the p-well.
