Abstract: A flat pressure sensor of the invention is prepared by processing a thin film of a polymer material to have plurality of substantially square openings 24. A planar member 22 of the flat pressure sensor thus obtained has a net-like structure including multiple element formation areas 26 and multiple bridging areas 28 that respectively bridge the multiple element formation areas 26. Pressure sensor elements 30 are provided in the multiple element formation areas 26 of the planar member 22. A wiring to the pressure sensor elements 30 is formed on the multiple bridging areas 28. The net-like structure enables the flat pressure sensor to be stretched in diagonal directions without arrangement of the bridging areas 28 and to be deformed to a curved surface. The flat pressure sensor of the invention is thus attached to a curved surface, for example, a spherical surface.

Abstract: Optical sensors containing reduced amounts of cross talk, as well as methods for making and using such sensors are described. The sensors contain a light absorption coating that is placed on a portion of the external surface of the optical sensor near the detector. This absorption coating reduces the amount of cross talk by reducing the amount of light reflected inside a transparent package of the sensor. As well, the coating can also reduce the amount of ambient and/or stray light that enters the sensor. The coating adds little cost or complexity to the manufacturing process for the sensors, yet reduces the cross talk without substantially increasing the size of the sensor or without increasing any reliability risks. Other embodiments are also described.

Abstract: Systems and methods detect changes in incident optical radiation at high frequencies. A detector having one or more asymmetrically conductive areas, formed of relaxation semiconductor material, is configured with at least two electrical contacts, positioned on opposite sides of an active area. Asymmetrical conductivity, for example provided by use of one doped contact and one un-doped contact, creates a transient voltage across the active area, which is measured by electronics connected with the electrical contacts. The transient voltage indicates changes in incident optical radiation, which may be distributed spatially uniformly over the system.

Abstract: A device for detecting radiation direction is an integrated circuit that includes a first and second phototransistor positioned anti-parallel with respect to each other and a reference phototransistor. The device does not require impinging radiation to be mechanically aligned using pinholes, apertures or mechanical slits. The first phototransistor detects the direction of the radiation in an x-plane, and the second phototransistor detects the direction of the radiation in the y-plane. The first and second phototransistors have two differential pairs. The P type base regions are formed in the plane of the silicon to form opposing sidewalls for receiving radiation signals from a radiation source. A current is induced in the PN junction of each phototransistor, thereby causing a current output on the emitters of the phototransistors. The differential currents represent rectangular coordinates describing the direction of the radiation detected on the plane. The reference transistor is a plane phototransistor, and its single current output is used to normalize the differential outputs of the first and second phototransistors. A system that integrates the detection device to determine the azimuth and elevation (spherical coordinates) of the impinging radiation includes a device that translates the normalized current outputs (rectangular coordinates) into spherical coordinates.
