Abstract: An operation switch includes: a capacitance sensor that generates three or more detection signals in response to approach or contact of an object to respective three or more electrodes; a determination circuit that determines whether or not the object is a living body based on one or more detection signals selected from the three or more detection signals, the one or more detection signals excluding a detection signal having a maximum intensity among the three or more detection signals; and a controller that, when the object is determined to be a living body, generates an operation signal for operating a predetermined device.

Abstract: A control switch for controlling a level of an operation of an apparatus among operating levels including first, second, and third operating levels includes: sensors each of which, in operation, senses an object, the sensors including first, second, and third sensors arranged along one direction, the first, second, and third sensors being assigned first, second, and third level values, respectively; an acquisition circuit that, in operation, acquires a moving velocity of the object along the direction with the first, second, and third sensors; a change circuit that, in operation, changes at least two of the first, second, and third level values according to the moving velocity; and a control circuit that, in operation, causes the apparatus to operate at an operating level corresponding to the level value assigned to one of the first, second, and third sensors which has sensed the object.

Abstract: The error correction processing includes: data reproduction processing of reproducing recording data, constituted by a plurality of data units each made of a plurality of bits, from a recording medium sequentially; error correction processing of performing error correction in the row direction and error correction in the column direction at least once for an error correction code block that has the reproduced recording data arranged in the row direction over a plurality of rows; determination processing of determining whether uncorrectable data is left behind after execution of the error correction processing; and erasure correction processing of performing, when it is determined that uncorrectable data is left behind, column-direction error correction considering data constituting at least one row of the error correction code block as erasure data, even in cases where uncorrectable data in the error correction in the row direction is not left behind.

Abstract: A settings changing system can power off only the mobile terminal apparatus of a user entering a specific institution without fail. The mobile terminal apparatus obtains ticket information from a ticket issue server through a base station and a network, and stores the information on a built-in contactless IC card. When the mobile terminal apparatus is put over a reader/writer mounted in the gate of a concert hall, theater, stadium, etc., the settings of the mobile terminal apparatus are automatically rewritten according to information from the reader/writer through the contactless IC card, and the set state (ON/OFF of the power and the manner mode) of the mobile terminal apparatus is changed.

Abstract: When data recording is interrupted, a location at which data have been last recorded is accurately detected and a seamless restart of the recording is achieved even if reproducing errors occur due to scratches or the like on an optical disk. A pattern data that indicates a pit pattern of data to be recorded or having been recorded is compared to a pattern data that is reproduced within a predetermined range (window) of clock cycles, and when a match is obtained, a recording restart signal is output to restart the recording operation.

Abstract: A mobile communication terminal having, in addition to a conversation function, a function of inputting data from another medium, and a function of sending and receiving an electronic mail of the present invention includes a first and a second memory. The first memory stores dictionary data received from another medium. The second memory stores a copy of the dictionary data when characters are to be edited.

Abstract: At reception of a call as a video telephone from a communicating terminal, an image and voice and sound to be sent to the communicating terminal can be automatically selected to be sent to the communicating terminal according to the communicating party having issued the call. A telephone book table includes a telephone number, a name identifying a user of a portable telephone assigned with the telephone number, and a screen display method of sending a reply when a call is received from the portable telephone having the telephone number as a communicating terminal with a relationship between established between the items. At reception of a call as a video telephone from a communicating terminal, if the call is from a communicating party with an issuing party number, a controller makes a search through the table to determine whether or not the table contains a telephone number of the communicating terminal from which the call is received.
