摘要： A humanoid detector for detecting a humanoid in a surveillance area that substantially reduces false intruder indications by having two types of sensors that provide two types of information of the surveillance area, is disclosed. A first sensor detects light images and determines a size of a moving object within the surveillance area and compares the size of detected moving objects to a threshold size to reduce intruder detection caused by small animals. A second sensor detects infrared radiation from the surveillance area provides a detected infrared radiation signal. A decision circuit receives the sensor signals and provides a decision signal that indicates a human intruder in the surveillance area when, simultaneously, the size of the moving body is greater than that of a small animal and the detected infrared radiation indicates that the moving body is a heat producing body. In order to compensate for differences in the sensors and to account for different physical properties in the surveillance area, the decision circuit holds high an intruder signal for a predetermined time from each sensor. Thus, if a signal occurs that indicates a moving body is larger than a small animal, that signal is held for a predetermined time interval and if a signal indicates a sufficient increase in the infrared radiation occurs while the moving body signal is being held, then the decision circuit determines that a human intruder has entered the surveillance area. The decision signal may be used to trigger an audible or visible indication.

摘要： The mirror device has a mirror 2, and a supporting mechanism which elastically supports the mirror 2 on a substrate 1 in a state in which the mirror floats from the substrate 1, so that the mirror can be inclined in an arbitrary direction. The supporting mechanism has three supporting parts 3A, 3B and 3C that mechanically connect the substrate 1 and mirror 2. Each of the supporting parts 3A, 3B and 3C has one or more plate spring parts 5 that are constructed from a thin film consisting of one or more layers. One end portion of each plate spring part 5 is connected to the substrate 1 via a leg part 9 which has a rising part that rises from the substrate 1. The other end portion of the plate spring part 5 is mechanically connected to the mirror 2 via a connecting part which has a rising part that rises from this other end portion. The mirror 2 is supported on the substrate 1 only via the plate spring part 5 of the respective 3A, 3B and 3C. As a result, compactness and mass production characteristics can be greatly improved while maintaining superior optical characteristics.

摘要： A power source is electrically connected to a capacitance element arranged corresponding to either a Shottky barrier diode (SBD) or a bolometer at a predetermined timing through a resistor by a driving pulse provided from a horizontal scanning circuit and a driving pulse provided from a vertical scanning circuit. At this time, charges charged by a voltage of the power source in the Shottky barrier diode are discharged by either a reverse current of the Shottky barrier diode or a current through the bolometer, immediately after the power source is disconnected from the capacitance element, arranged for either the Shottky barrier diode or the bolometer. After a storing period of time, when the power source and the capacitance element are connected, the charges corresponding to the charge amount discharged for the storing period of time are charged in the capacitance element. At this time, a voltage according to the charge amount is provided. Thus, an infrared-ray image sensor can be obtained using a Shottky barrier diode or a bolometer.

摘要： The movable part 21 is fastened to the substrate 11 via flexure parts 27a and 27b, and can move upward and downward with respect to the substrate 11. The substrate 11 also serves as a fixed electrode. The movable part 21 has second electrode parts 23a and 23b which can generate an electrostatic force between these electrode parts and the substrate 11 by means of a voltage that is applied across these electrode parts and the substrate 11, and a current path 25 which is disposed in a magnetic field, and which generates a Lorentz force when a current is passed through this current path. A mirror 12 which advances into and withdraws from the light path is disposed on the movable part 21. As a result, the mobility range of the movable part can be broadened, and the power consumption can be reduced, without applying a high voltage or sacrificing small size.

摘要： Radiation detectors are disclosed that include at least one element (pixel). In a pixel, a desired positional relationship between two “effecting” elements is maintained regardless of changes in temperature or other prevailing variable. The detectors can be “electrical capacitance” or “optical-readout” types. A pixel of the electrical capacitance type includes two electrodes (reference electrode and response electrode) that face each other and have a set gap therebetween. The electrodes are attached to respective displaceable members (configured as thermal bimorphs) having identical structures. A pixel of the optical readout type includes a half-mirror and a reflector that face each other and have a set gap therebetween. The half-mirror and reflector are attached to respective displaceable members. Radiation is absorbed by a radiation absorber that transfers the heat to certain displaceable members that bend to tilt accordingly. Other displaceable members are not heated and do not bend. The displaceable members are formable simultaneously during respective fabrication steps.

摘要： Thermographic infrared cameras are disclosed that comprise an infrared image sensor having linearly positioned thermosensing elements. A physical property of each thermosensing element changes in proportion to a corresponding temperature change caused by infrared irradiation incident on the thermosensing element. The infrared image sensor comprises a read device that reads signals from each thermosensing element in an ordered manner. A logarithmic converter receives signals from the infrared image sensor and outputs corresponding logarithmic values of the signals. An image information output device receives the logarithmic values from the logarithmic converter and outputs a corresponding infrared image. Such thermographic infrared cameras can further comprise a reference infrared image sensor. The reference infrared image sensor includes reference thermosensing elements each having a physical property that exhibits a change in value in proportion to a temperature change of the respective thermosensing element. A compensating logarithmic converter outputs a logarithmic value of the ratio of the signal read by the infrared sensor and the signal read by the reference infrared sensor. An image information output device receives the logarithmic values output by the compensating logarithmic converter and outputs corresponding infrared image information.

摘要： A movable plate is fastened to a substrate via flexure parts and can move upward and downward with respect to the substrate. The substrate serves as a fixed electrode. The movable plate has second electrode parts which generate an electrostatic force between these electrode parts and the substrate by virtue of a voltage that is applied across these electrode parts and the substrate and a current path which is disposed in a magnetic field, and which generates a Lorentz force when powered. A mirror advances into and withdraws from the optical path. When the movable plate moves from the lower position in which the electrostatic force is increased to the upper position, the control part controls the current so that the Lorentz force is generated in a downward orientation and gradually decreases while the movable plate moves from an intermediate position to the upper position.
