摘要： A levitating support and positioning system (10) is provided for orienting an electromagnetic energy reflecting assembly (40). System (10) includes a reflective member (60) supported by an annular ring (50) having a plurality of superconductors (70) disposed thereon. Ring (50) is levitated above a base surface (20) by means of a plurality of electromagnetic assemblies (30), each of the electromagnetic assemblies (30) corresponding to a respective one of the plurality of superconductive elements (70), whereby the magnetic fields generated by the electromagnetic assemblies (30) are repelled by the respective superconductive elements. The orientation of the support ring (50), and the reflector therewith, is adjusted by changing the relative magnetic field strength between each of the electromagnetic assemblies (30), allowing the reflector to be directed in both elevation and azimuth.

摘要： A static RAM cell (11) is constructed utilizing low resistivity positive and negative power supply leads (13,14), thus eliminating the problem of instability of the data stored within the cell. The negative power supply lead is formed of a first layer of low resistivity polycrystalline silicon/tantalum silicide, and the positive power supply lead is formed of a second layer of polycrystalline silicon. The use of a low resistivity negative power supply lead causes the voltage drop on the negative power supply lead to be substantially reduced as compared with prior art devices, thereby providing during the read operation substantially equal voltages to the gates of the two bistable transistors of each cell, thus eliminating the problem of instability during reading.Depletion load devices (11,12) are formed utilizing the layer of polycrystalline silicon as the source, drain and channel and the layer of polycrystalline silicon/tantalum silicide as the gate. In this manner, silicon area is not required to form the depletion load devices, thus minimizing cell size.

摘要： A fiber optic sensor flatpack capable of extremely sensitive strain measurements, without the complexity, high installation costs, and sensitivity to extraneous effects associated with conventional strain gage technologies, such as resistance foil strain gages. The “flatpack” strain sensor houses two individual sensors to allow for accurate temperature compensated strain measurements. The packaging method incorporates plastic materials and laminate manufacturing techniques, which results in a fully hermetic package that is resistant to harsh environmental conditions. Multiple flatpacks can be connected in series and interrogated along a single optical fiber cable when the flatpacks are constructed with fiber optic sensors that can be serially multiplexed, such as with Bragg grating sensors.

摘要： A computer system includes a software UART emulation and uses standard operating system protocols to minimized the chance of I/O conflicts between a serial device having a UART and a non-standard serial device which communicates through the UART emulation. A COM driver which can replace a standard COM driver in an operating environment such as provided by Microsoft WINDOWS.TM. contains the UART emulation. The COM driver can also include a software modem that is accessed through the UART emulation in the same manner as a modem having a hardware UART. The COM driver also sets the device address of the non-standard device on an ISA bus by determining the device addresses of COM port I/O slots used by UARTs, sending a predetermined pattern on the ISA bus to indicate a device address is to come, and then sending a value indicating a device address not used by the UARTs. The pattern has a length sufficient to make inadvertent generation of the pattern unlikely. The non-standard device recognizes the predetermined pattern and selects a device address according to the value from the COM driver.

摘要： An HSP communications system contains a host computer which executes a software modem program and a device containing a circular buffer and a D/A converter. Typically, the host executes update routines in response to interrupts from the device and writes to the circular buffer digital samples representing amplitudes of an analog signal complying with a desired communication protocol. The samples pass through the circular buffer to the D/A converter which converts the samples into an analog communication signal. In environments such as multi-tasking systems, the host may occasionally skip interrupts and not provide new samples when required. In this case, the D/A converter reuses samples in the circular buffer to generate a maintenance signal. The maintenance signal typically does not convey correct data but is sufficient to maintain a communication link and prevent a remote device from disconnecting or entering a retrain mode. To provide a smoother maintenance signal, the circular buffer's size contains samples for an integral number of periods at the carrier and baud frequency of the desired protocol. Error correction and retransmission replace incorrect or lost data.

摘要： A method of manufacturing a silicon gate MIS device providing automatic formation and alignment of the gate structure during formation of adjacent impurity regions. In a preferred embodiment, the process is for the gate structure and source and drain of silicon gate FETs. The layered gate constituents-- typically oxide and silicon-- are formed on a semiconductor wafer. A photoresist mask which is larger than the desired gate size is formed on the silicon and the silicon is etched to a predetermined size beneath the overhanging mask. A deposition mask in the form of the photoresist mask or the gate silicon oxide and which is of the same size as the photoresist mask, is used to control the deposition of impurities within predetermined surface areas of the substrate which are spaced a predetermined distance from the silicon gate boundaries. By diffusion, the impurities are driven into the substrate to the desired depth to complete the source and drain, which are thereby driven laterally into coincidence with the gate boundaries. The aligned, non-overlapping relationship of the gate structure with the source and drain minimizes gate overlap capacitance.
