20100223147 | COMMODITY SETTLEMENT SYSTEM, METHOD THEREFOR AND MOBIL TERMINAL - A commodity settlement system processes settlement for a commodity carrying an RF tag, communicating with the RF tag for data associated with the commodity stored in an RF tag. The RF tag comprises a capacitor, a memory, and an antenna, the RF tag being capable of receiving a radiowave from an external device, charges the capacitor with a direct current converted by the rectifier circuit from a current induced in the antenna by receiving a radiowave from an external device, and stores temporary settlement information in the memory. The commodity settlement system includes a first RF tag reader/writer connected to an antenna disposed on a commodity shelf. The first RF tag reader/writer sets the temporary settlement information in the memory to an “unsettled” state through the antenna disposed on the commodity shelf at intervals of a predetermined time. | 09-02-2010 |
20110062234 | ANTENNA DEVICE AND RFID TAG READER HAVING THE SAME - An antenna device includes a first conductive plate, a second conductive plate, arranged in parallel with the first conductive plate, which has at least one slot formed thereon, a power feeding element located between the first and second conductive plates to feed power to the first conductive plate, and a shutter configured to be movable to close/open the slot of the second conductive plate. | 03-17-2011 |
20110063086 | RF TAG READER AND WRITER - There is provided an RF tag reader and writer including: a transmission antenna configured to transmit a desired signal; a receiving antenna configured to receive radio waves transmitted from an RF tag which is a communication target; a return-loss determination unit configured to determine the receiving intensity of the receiving antenna with respect to reflected waves of radio waves radiated from the transmission antenna; and a reading control unit configured to start a reading operation of the RF tag by being triggered by a return loss value determined by the return-loss determination unit. | 03-17-2011 |
20110199277 | ANTENNA AND PORTABLE APPARATUS - According to one embodiment, an antenna mounted on a portable apparatus having a hinge structure includes: a radiating element formed in a disk shape and configured to radiate a radio wave; a power feeding element exciting the radiating element; and a ground plate including a bottom surface arranged in parallel to the radiating element and the power feeding element and a side surface configured to allow a power feeding path feeding electric power to the power feeding element to pass in an area different from an area opposed to the hinge structure. | 08-18-2011 |
20110199282 | ANTENNA AND PORTABLE APPARATUS - According to one embodiment, an antenna includes: a disk-shaped radiating element having an opening in a center area and configured to radiate a radio wave; a ground plate configured to support the radiating element and having a surface parallel to the radiating element; and a power feeding element exciting the radiating element, a part of the power feeding element being located on an inner side of the opening when viewed from a predetermined direction orthogonal to a surface on which the radiating element is located. | 08-18-2011 |
20120104227 | COORDINATE RECOGNIZING APPARATUS AND CONTROL METHOD THEREFOR - According to one embodiment, a coordinate recognizing apparatus includes plural light emitting elements, plural light receiving elements, a memory, and a controller. The memory stores, concerning plural pairs of the light emitting elements and the light receiving elements set in advance, reference values used for determination of blocking of a light path. The controller performs, concerning the respective pairs, actions for collecting, plural times, a difference between first intensity indicated by a detection signal output from the light receiving element, which is a pair of the light emitting element, in a state in which the light emitting element is caused to emit light and second intensity indicated by a detection signal output from the light receiving element during non-light emission of the light emitting element and updating the reference value of the pair stored in the memory using a minimum of differences collected plural times. | 05-03-2012 |
20120105378 | INPUT APPARATUS AND METHOD OF CONTROLLING THE SAME - According to one embodiment, an input apparatus comprises an input detector, a vibration detector, a controller, and a sensitivity adjustment unit. The input detector detects an input by the blockage of a light beam to scan a scan region. The vibration detector detects a vibration equal to or more than a set sensitivity applied to the input detector. The controller stops the light beam scanning when the input detector detects no inputs for a given length of time. The controller restores the light beam scanning when the vibration detector detects a vibration. The sensitivity adjustment unit changes the sensitivity of the vibration detector to be weaker than the set sensitivity when the input detector detects no inputs and the vibration detector continuously detects vibrations after the controller has restored the light beam scanning. | 05-03-2012 |
20120105379 | COORDINATE RECOGNITION APPARATUS AND COORDINATE RECOGNITION METHOD - According to one embodiment, a coordinate recognition apparatus includes a coordinate input unit, an adjustment unit, a judgment unit, a scan control unit, and a recognition unit. The adjustment unit adjusts an offset voltage of a sensor amplifier that amplifies a sensor signal output from the light-receiving element. The judgment unit judges whether disturbance light received by the light-receiving element has an influence. The scan control unit sets the number of scans with the light beam to scan the coordinate input unit when the judgment unit judges that the disturbance light has an influence to be greater than the number of scans when the judgment unit judges that the disturbance light has no influence. The recognition unit recognizes the coordinates input by the coordinate input unit in accordance with a change of the sensor signal output from the light-receiving element. | 05-03-2012 |
20120136624 | COORDINATE RECOGNITION APPARATUS AND CONTROL METHOD THEREOF - According to one embodiment, a coordinate recognition apparatus includes a detection device, a first calculation section, a second calculation section, and a setting section. The detection device detects an operation for an operation area. The first calculation section calculates coordinates of an operation position by a user on the basis of the detection result of the detection device. The second calculation section calculates the smoothed coordinates by smoothing a particular number m (m>0) of samples among the coordinates calculated by the first calculation section counted from the new one in a calculation order. The setting section sets a value of the number m of samples to be smaller as the speed of movement of the operation position is higher. | 05-31-2012 |
