Abstract: A threshold device or comparator comprises an array of energy emitters, e.g. light emitting diodes (16) or diode arrangements. The bits of a binary string are supplied to respective diodes or diode arrangements, which have the property of emitting energy of a distinguishable different characteristic depending on whether the applied bit is a 0 or 1. Sensors (18, 20) sensitive to the intensities of the respective different characteristics detect the intensities and a comparator 24 provides an output indicating the relative quantities of 0's and 1's in the binary string.

Abstract: An optical probe, which is particularly suited to for use in measurements on tissue material of a patient. In one embodiment, the probe comprises upper and lower housing elements incorporating a light energy source and corresponding detector. The tissue material of the patient is disposed between the upper and lower housing elements such that the light energy emitted by the source passes through the tissue material to the detector. A plurality of light shields are attached to one or both of the housing elements to reduce the amount of ambient and reflected light reaching the detector. Additionally, various portions of the upper and lower housing elements and shields utilize light absorbent coloration and/or coatings which further mitigate the effects of undesired ambient and reflected light, thereby reducing noise generated within the instrument and increasing its accuracy. In one embodiment, the light shields are made removable from the optical probe, thereby facilitating replacement. A circuit for monitoring the condition of the probe, and indicating when replacement of the probe is desirable, is also disclosed.

Abstract: An object of the present invention is to provide an optical receiving circuit that it is possible to even a gain during a broad frequency band. The optical receiving circuit according to the present invention comprises an amplifier for feeding back negatively and amplifying an input signal, and a reflection coefficient setting circuit for setting an input reflection coefficient of the amplifier. For example, the reflection coefficient setting circuit has a resister Rin. One end of the resistor Rin is connected to an input terminal of the amplifier, and the other end of the resistor Rin is supplied with a voltage Vin substantially equal to a direct-current component of an input signal IN. The resistance of the resistor Rin is set so that the input reflection efficient becomes about less than about 0.3. Therefore, a peaking does not occur even at a resonance point, and it is possible to even a gain during a broad frequency band.

Abstract: Many applications of radiant energy transducer systems call for specific performance characteristics over predetermined fields or surfaces. Constructive occlusion utilizes diffuse reflectivity and a mask sized/positioned to occlude an active optical area, such as an aperture of a reflective cavity, to provide tailored performance characteristics. Constructive occlusion alone or in combination with other techniques enable tailoring of the performance of a radiant energy transducer system to meet requirements of specific applications. One mechanism used to further tailor performance involves a non-diffuse reflective shoulder along a peripheral section of the mask and cavity system. Another technique involves using a retro-reflective surface, for example along a portion of the periphery of the system. Another technique involves use of a reflective wall along one side of the system, to limit the field of view to angles on the opposite side of the axis of the mask and cavity configuration.

Abstract: A photoconductive semiconductor switch with tailored doping profile zones beneath and extending laterally from the electrical contacts to the device. The zones are of sufficient depth and lateral extent to isolate the contacts from damage caused by the high current filaments that are created in the device when it is turned on. The zones may be formed by etching depressions into the substrate, then conducting epitaxial regrowth in the depressions with material of the desired doping profile. They may be formed by surface epitaxy. They may also be formed by deep diffusion processes. The zones act to reduce the energy density at the contacts by suppressing collective impact ionization and formation of filaments near the contact and by reducing current intensity at the contact through enhanced current spreading within the zones.
