A device for the high-speed analysis of photon- or particle-generated image data or for the high-speed energy-discrimination analysis of photon- or particle-counting data. The device uses a sensor that collects the photons or particles on an array of solid state detectors, as electrical analog signals, and stores the analog-signal information on capacitors of readout arrays associated with the detector arrays. Integration of the photon or particle flux signals on the readout arrays proceeds for a given time frame and then image-related signals are transferred to an analog correction processor. The analog correction processor is comprised of one or more integrated circuit chips where each chip contains an array of correction processor unit cells. In these unit cells signals are corrected, in parallel, for gain and offset nonuniformities in the detection and processing chain. Corrections to all the signals are made in a time frame or less and the information is then transferred to an analog image processor. Particle-counting data is transferred directly from the readout array chips to the analog image processor. The analog image processor is comprised of one or more integrated circuit chips where each chip is made up of an array of image processor unit cells. Each unit cell contains circuitry for implementing an image processing or energy discrimination algorithm, and circuitry for outputting the signals and / or the position of only those unit cells for which the algorithm is satisfied. The analog image processor chip may also contain circuitry that counts the number of cells for which the algorithms have been satisfied. The analog image processor implements the algorithm and outputs the data in a time frame or less.

An implanted microphone is provided that has reduced sensitivity to vibration and attendant acceleration forces. In this regard, the microphone differentiates between the desirable and undesirable components of a transcutaneously received signal. More specifically, the present invention utilizes an output that is indicative of acceleration forces acting on the implanted microphone (e.g., an acceleration signal) to counteract and / or cancel the effects of acceleration induced pressures in an output signal of a microphone diaphragm. This may be done in a variety of ways, including but not limited to, pneumatically, mechanically, electrical analog, or digitally, or combinations thereof. In one arrangement, the generated output may be filtered to match the an acceleration response of the output signal of the microphone diaphragm such that upon removal of the motion signal from the microphone output, the remaining signal is an acoustic signal.

The system includes an array of transducers that simultaneously senses multiple intralumenal pressures, a data acquisition module that acquires and stores samples of the measured pressures, software routines for signal analysis, a software module for multi-dimensional data display presentations, and a software module to perform pattern recognition on the acquired data set to identify potential maladies that may be indicated by the analysis. The transduction elements are cylindrical segments that deform according to the circumferential pressures encountered. Distributing a quantity of these sensor segments at desired locations along a flexible support structure and providing a flexible sheath over the entire length forms the sensor array. Measuring the sensor deformation provides an electrical analog of the pressure causing the deformation. Acquiring these measurements in a suitable data acquisition and processing unit, including a display, printing, and plotting capability, completes the hardware elements. Integrated software modules complete the system.

The invention relates to wireless biotelemetry of low level bioelectric and biosensor signals by directly modulating the backscatter of a resonant circuit. Low level electrical analog or digital signals are directly applied to a resonant circuit containing a voltage-variable capacitor such as a varactor diode, that proportionally shifts the resonant frequency and so amplitude of radiofrequency backscatter in a way that represents analog bioelectric or biosensor waveform data. By strongly driving the resonant circuit with a radiofrequency source, a voltage variable capacitance can be caused to amplify the bio-signal level by a parametric process and so provide sufficient sensitivity to telemeter for low millivolt and microvolt level signals without additional amplification. A feature of the device is its simplicity and that it accomplishes both modulation and preamplification of low level sensor signals by the same variable capacitance circuit which reduces the device size and power consumption.

An energy generator using a potential energy gradient applied to a non-Maxwellian gas occupying and restricted to a volume, to generate a temperature difference between regions in this volume. This temperature difference occurs in the absence of any flow of particles in or out of this volume. The volume can be embodied by a semiconductor and particles, by electrons or holes in the semiconductor. Electrical power can be generated from the temperature difference by connecting a Seebeck device across it or by using the temperature difference to drive an electrical analog of the fixed-vane Crookes radiometer to propel electrical carriers. When two such Crookes radiometers are formed across a junction, electrons and holes can be driven toward each other in the absence of any external voltage source, thereby producing electromagnetic radiation. Applications include heating, cooling, electrical energy production and lighting.
