  • Patent number: 7606399
    Abstract: A sensor cell includes a sensor electrode (101) formed on a substrate (100), a signal output unit (16) which outputs a signal corresponding to a capacitance (Cf) formed between the sensor electrode and the surface of a finger (3), a high-sensitivity electrode (103) formed on the substrate so as to be insulated and isolated from the sensor electrode, and a potential controller (14) which controls the potential of the finger surface via a capacitance (Cc) formed between the high-sensitivity electrode and the finger surface by controlling the potential of the high-sensitivity electrode. In this arrangement, when the resistance of the finger is high, the potential of the finger surface can be controlled so as not to fluctuate with the potential change of the sensor electrode.

  • Patent number: 7548636
    Abstract: A response signal generating unit (3) applies a predetermined supply signal (2S) to a detection element (1) and outputs, as a response signal (3S), a signal which has changed in accordance with the impedance of an object (10) with which the unit is in contact through the detection element (1). A waveform information detection unit (4) detects waveform information corresponding to the impedance of the object (10) on the basis of the response signal (3S) from the response signal generating unit (3), and outputs a detection signal (4S) representing the waveform information. A biometric recognition unit (5) determines on the basis of the detection signal (4S) from the waveform information detection unit (4) whether or not the object (10) is a living body.

  • Patent number: 7440534
    Abstract: A master latch (1) is formed from a static circuit, and a slave latch (2) is formed from a dynamic circuit. The number of circuit elements can be smaller as compared to a slave latch formed from a static circuit so that the size and area of a master-slave flip-flop can be reduced. Since the master latch is formed from a static circuit, data can be held stably during the standby time by setting the master latch in a data holding state.

  • Patent number: 7381663
    Abstract: A structure (113b) which includes an overhang and a support portion supporting substantially the center of the overhang, and in which the area of the support portion is smaller than the area of the overhang in the two-dimensional direction of an upper electrode (1110b) is formed on the upper electrode (110a) in a region above each lower electrode 105a in one-to-one correspondence with the lower electrode (105a). An object of surface shape sensing, e.g., the tip of a finger (1602) touches the surface of the overhang of the structure (113b), and the support portion of the structure (113b) whose overhang is in contact with the object of sensing pushes down a portion of the upper electrode (110a) toward the lower electrode (105a), thereby deforming the upper electrode (110a).
