Abstract: A process for fabricating oxide-isolated vertical bipolar transistors and complementary oxide-isolated lateral bipolar transistors incorporates the steps of growing a doped epitaxial layer of single-crystal silicon on a silicon substrate, applying a first insulation material in a selected pattern over the epitaxial layer to define oxide-isolation regions and device regions, etching grooves in the areas in which oxide-isolation regions will be formed, applying a self-aligned base insulation material over those portions of the interface between the first insulation material and the grooves which bound the region between the base of any vertical bipolar transistor to be formed and the emitter of any lateral bipolar transistor to be formed, applying an impurity of a conductivity type opposite to the conductivity type of the epitaxial layer to those groove areas not covered by the self-aligned base insulation material, the impurity serving to prevent emitter-to-collector inversion along the wall of the base of any vertical bipolar transistor without shorting the emitter and collector of any lateral bipolar transistor, forming oxide-isolation regions in the grooves and forming the vertical bipolar transistors and the lateral bipolar transistors in the device regions. The process of the present invention will produce discrete lateral bipolar transistors, discrete vertical bipolar transistors capable of operation in the conventional mode or in the inverse mode, or a composite structure which merges both a vertical bipolar transistor and a lateral bipolar transistor together on the same silicon island to form an injection-logic gate in which the base of the vertical bipolar transistor serves as the collector of the lateral bipolar transistor, the vertical transistor being operated in the inverse mode.

Abstract: An electrode array has a flexible body supporting a plurality of electrodes. Each electrode comprises an exposed connector pad at the upper end of the body, an exposed recording/stimulating pad at the lower end of the body, and a conductor located within the body and electrically connecting the connector pad and the recording/stimulating pad. In one embodiment the electrode array has an elongated recording/stimulating portion coiled or folded to distribute the exposed recording/stimulating pads in three dimensions. An implantation method employs an introducer with a helical portion to which an end of the flexible electrode is attached. The helical portion straightens to pass through a small-diameter cannula and then resumes its helical configuration to place the recording/stimulating portion of the attached electrode in a helix within the patient's tissues.

Abstract: A pressure cavity is durable, stable, and biocompatible and configured in such a way that it constitutes pico to nanoliter-scale volume. The pressure cavity is hermetically sealed from the exterior environment while maintaining the ability to communicate with other devices. Micromachined, hermetically-sealed sensors are configured to receive power and return information through direct electrical contact with external electronics. The pressure cavity and sensor components disposed therein are hermetically sealed from the ambient in order to reduce drift and instability within the sensor. The sensor is designed for harsh and biological environments, e.g. intracorporeal implantation and in vivo use. Additionally, novel manufacturing methods are employed to construct the sensors.

The first LUT is configured to provide a first correction value based on a first version of the signal, where the first correction value are for use in correcting static non-linearity associated with the channel. The second LUT is configured to provide a second correction value based on a second version of the signal, where the second correction value are for use in correcting dynamic non-linearity associated with the channel. Digital signal processing logic is configured to use the first correction value, the second correction value, and the signal in order to compensate for harmonic distortion from the channel.

Abstract: A ventricular assist device comprises a sheet of hydraulically actuated material that can be affixed to prescribed locations on the surface of the heart to assist areas of the heart that do not contract normally. The material is comprised of a network of contractible unit cells that individually contract when fluid is pumped into them. These unit cells are connected together in a network that causes the sheet to contract radially inward. This contraction causes the sheet to transmit forces to the heart to assist in its natural contraction. A sensing function coordinates the contraction of the sheet with the contraction of the heart. The change in shape of the device is accomplished by distributing pressurized fluid throughout the spaces of the device by way of a network of channels. When pressure is removed from the fluid system, it assumes a deenergized “rest” position in which it does not transmit any forces to the surface of the heart. This property of the device prevents the device from inhibiting the heart's natural contractions in the event of a failure of the device or a loss of hydraulic power.

Abstract translation: 心室辅助装置包括一片液压致动材料片，该片材可以固定在心脏表面上的规定位置，以帮助心脏不能正常收缩的区域。 该材料由可收缩的单体电池网络组成，当将流体泵入其中时单独收缩。 这些单电池在网络中连接在一起，导致片材向内径向收缩。 这种收缩导致片材将力传递到心脏以帮助其自然收缩。 检测功能可以协调纸张与心脏收缩的收缩。 设备形状的变化通过通过通道网络将加压流体分配到设备的整个空间中来实现。 当压力从流体系统移除时，它承受断电的“静止”位置，在该位置，它不会将任何力传递到心脏表面。 该装置的这种特性防止装置在装置发生故障或液压动力损失的情况下抑制心脏的自然收缩。

Abstract: A wireless sensor for indicating a physical state within an environment includes a unitary housing defining a cavity. A structure located within the cavity of the housing has elements providing capacitance, the elements being arranged such that the distance and thereby the capacitance of the structure changes when a physical state of the environment changes. The structure has a resonant frequency based at least in part on the capacitance of the structure when in the presence of a fluctuating electromagnetic field. When the sensor is positioned within an environment and is subjected to a fluctuating electromagnetic field, the resonant frequency indicates the physical state of the environment.
