Abstract: An electronic device includes transmission antennas, reception antennas, and an electronic component. The transmission antennas each transmit a transmission wave. The reception antennas each receive a reflected wave that is the transmission wave having been reflected. The electronic component outputs respective transmission signals to the transmission antennas and receive respective reception signals from the reception antennas. The electronic component has a first edge where transmission terminals that output the respective transmission signals to the transmission antennas are arranged, and a second edge where reception terminals that receive the respective reception signals from the reception antennas are arranged. At least one of the first edge or the second edge is located obliquely relative to at least one of a direction in which respective feeding points of the transmission antennas are arranged or a direction in which respective feeding points of the reception antennas are arranged.

Abstract: An electronic device includes a transmission unit that transmits a transmission wave from a transmission antenna; a reception unit that receives, from a reception antenna, a reflected wave of the transmission wave; a controller that detects an object that reflects the transmission wave; a power supply device that supplies electric power to at least any of the foregoing components; and a substrate having the foregoing components thereon. The transmission and reception antennas are disposed on a first surface of the substrate. The controller and the power supply device are disposed on a second surface of the substrate opposite to the first surface. The substrate includes a waveguide that guides the transmission wave and/or the reflected wave between the first and second surfaces and is covered with an electromagnetic wave shielding member apart from the second surface by a distance of ¼ of a wavelength of the transmission or reflected wave.

Abstract: An electronic device comprises: a transmission antenna configured to transmit transmission waves; a reception antenna configured to receive reflected waves resulting from reflection of the transmission waves; and a controller. The controller is configured to detect an object reflecting the transmission waves, based on a transmission signal transmitted as the transmission waves and a reception signal received as the reflected waves. The controller is configured to make a range of detection of the object by the transmission signal and the reception signal, variable.

Abstract: An electronic device includes a transmission antenna that transmits a transmission wave, a reception antenna that receives a reflected wave that is the reflected transmission wave, and a control unit that detects an object that reflects the transmission wave, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave. The electronic device transmits, to an information processing apparatus, sensing information based on the transmission signal and the reception signal at a location of the electronic device along with location information of the electronic device.

Abstract: An image display device includes a front plate and a rear plate opposing the front plate, the front plate being provided with phosphor film segments, resistance layers provided between the phosphor film segments, metal back layer segments provided on the phosphor film segments and the resistance layers, and high-voltage applying means which applies a high voltage to the metal back layer segments, the metal back layer segments being obtained by dividing a metal back layer along a first axis X with gaps Gx therebetween and along a second axis Y with gaps Gy (Gy>Gx) therebetween, the rear plate being provided with a plurality of electron emission elements. Those of the resistance layers which are provided in areas existing between the gaps Gy include first resistance layer segments adjacent to the phosphor film segments, and second resistance layer segments adjacent to the first resistance layer segments.

Abstract: An internal pressure measuring catheter is constituted by at least three lumens which are: an internal pressure measuring lumen whose distal end is open and whose proximal end is connected to an internal pressure measuring transducer; a position correcting liquid-charged lumen whose distal end is closed, in which a liquid is charged, and whose proximal end is connected to a liquid pressure measuring transducer; and a position correcting atmosphere-opened lumen whose distal end is closed and whose proximal end is open to the atmosphere. The adjoining surfaces of the distal end portions of the liquid-charged and atmosphere-opened lumens have a small hole through which the charged liquid can be brought into contact with the atmosphere through the atmosphere-opened lumen.

Abstract: A retrieval apparatus of this invention includes retrieval processing sections constituted by semiconductor IC elements attached to each of the objects to be retrieved, and an operation section for supplying a retrieval condition to these retrieval processing sections. In each retrieval processing section, retrieval item information of an object to be retrieved to which the individual section is attached is stored in a storage section, a retrieval condition signaled from the operation section is received and analyzed, the analysis result is collated with the information stored in the storage section, and if a coincidence is detected, signaling is performed by light or sound. The retrieval condition may be constituted using logical product, logical sum and logical negation operators.

Abstract: An information retrieval system in which various information is indexed synthetically into such relations as the synonym, the broader term and the narrower term to provide a thesaurus and the words are coded to provide a keyword relation table, an index table and a word table each stored in a memory device respectively so that the desired information retrieval operation may be conveniently performed with use of a computer system. Particularly, a memory capacity even for memory of the thesaurus of large scale may be reduced considerably with simplification of the computer system.
