摘要： The present invention relates to an improved installation for conveying electrical signals carried by a first triaxial cable (2) to a second triaxial cable (6) and vice versa. It comprises: a first interface (3) between the first triaxial cable (2) and a fibre optic cable (4) and a second interface (5) between the fibre optic cable (4) and the second triaxial cable (6). A television camera (7) is connected to a remote camera control unit (1) via this installation. The first triaxial cable (2) connects the camera control unit (1) with the first interface (3). The first interface (3) comprises a first adapter converting electrical signals, conveyed by the first triaxial cable (2), to optical signals. The fibre optic cable (4) transmits optical signals to the second interface (5). The second interface (5) comprises a second adapter converting optical signals to electrical signals. The second triaxial cable (6) transmits the electrical signals to the television camera (7). A mirror image of the adapters allows transmitting electrical signals from the camera (7) to the camera control unit (1). The interfaces comprise A/D converters and D/A converters repectively adapted to convert analogue signals from the triaxial cable into digital optical signal to be launched into the fibre and digital optical signals into analogue electrical signals.

摘要： The disclosure relates to method and apparatus for isolating sensitive regions of a semiconductor device by providing a thermal path or an electromagnetic shield. The thermal path may include vias having different length, depth and configuration such that the thermal path between the two regions is lengthened. In addition, the vias may be fully or partially filled with an insulating material having defined conductive properties to further retard heat electromagnetic or heat transmission between the regions. In another embodiment, electrical isolation between two regions is achieved by etching a closed loop or an open loop trench at the border of the regions and filling the trench with a conductive material to provide proper termination of electromagnetic fields within the substrate.

摘要： Computation-intensive applications such as sensor signal processing, sensor fusion, image processing, feature identification, pattern recognition, and early vision place stringent requirements on the computational capacity, size, weight, and power dissipation of modular computational systems intended for both embedded and high performance computer environments. Such ultra high speed, ultra high density computational modules will typically be configured with multiple processor, memory, dedicated sensor, and digital signal processing chips in close-packed multichip modules. The present invention relates to a novel architecture and associated apparatus for the development of highly multiplexed photonic interconnections between pairs of such electronic chips incorporated in vertical stacks within three-dimensional multichip module configurations. Vertical signal transmission through the chip substrates is accomplished by using a planar-waveguide-based optical power bus to provide a parallel array of beams to read out a modulator array that is flip-chip bonded to each silicon substrate. Local and quasi-local connectivity in the vertical dimension is accomplished by using diffractive optical structures that provide for both point-to-point interconnections and weighted fan-out within a local neighborhood. Global connectivity is incorporated by means of computer-generated volume holographic optical elements that are fabricated as a multilayer diffractive optical element. Several different architectural implementations of such computational modules are provided to address applications that include high-bandwidth two-dimensional displays, multilayer neural networks, image processors, multiple processors with access to shared memory, and rending engines for computer animation and graphics. In addition, subsystems of the computational-module architecture and apparatus are described that provide for compact optical readout of modulator-based flat panel displays.

摘要： The present invention relates to a novel source array comprising a plurality of sources of optical illumination that are at once both individually coherent and mutually incoherent. A primary application of such a source array is to provide the requisite optical source beams in a novel architecture and associated apparatus for the development of highly multiplexed photonic interconnection networks and holographic optical elements with maximum optical throughput efficiency and minimum interchannel crosstalk, based on parallel incoherent/coherent holographic recording and readout principles that are described herein. In one embodiment, the source array is configured from a plurality of coherent sources of illumination; in a second embodiment, a single source of coherent illumination is expanded to illuminate a phase modulator array, within which each separate phase modulator is driven at a distinct oscillation frequency such that the set of resultant modulated beams exhibits mutual incoherence. Such incoherent/coherent source arrays are critical for providing arbitrarily weighted and independent interconnections, which in turn are of potential importance in the development of neuro-optical computers, as well as photonic interconnection networks and multiplexed holographic optical elements. In addition, the extremely difficult problem of copying the contents of a three-dimensional holographic storage device in one step is enabled by utilization of the incoherent/coherent source arrays that are the key features of the present invention.

摘要： Techniques for on-chip detection of integrated circuit power supply noise are disclosed. By way of example, a technique for monitoring a power supply line in an integrated circuit includes the following steps/operations. A first signal and a second signal are preconditioned. The first signal is representative of a voltage of the power supply line being monitored. The second signal is representative of a voltage of a reference power supply line. Preconditioning includes shifting respective levels of the voltages such that the voltages are within an input voltage range of comparator circuitry. Then, the preconditioned first signal and the preconditioned second signal are compared in accordance with the comparator circuitry. Comparison includes detecting when a difference exists between the voltage level of the preconditioned first signal and the voltage level of the preconditioned second signal.
