Method for manufacturing a matrix type actuator

Patent number: 6988301

Abstract: A matrix type piezoelectric/electrostrictive (P/E) actuator includes a plurality of piezoelectric/electrostrictive elements, each including a piezoelectric/electrostrictive body and at least one pair of electrodes formed on a ceramic substrate. The matrix type P/E actuator is activated by the displacement of the piezoelectric/electrostrictive bodies. The piezoelectric/electrostrictive elements are joined to the ceramic substrate as respective unified bodies, and are two-dimensionally arranged independently from each other. The piezoelectric/electrostrictive actuator provides a greater displacement with a lower voltage, a high responsive speed, and a greater generating force, as well as enhancing the mounting ability and the integration. A method for manufacturing such a matrix type P/E actuator is also disclosed.

Image processing system and image processing method

Publication number: 20060008113

Abstract: This invention provides an image processing system and image processing method which can appropriately provide vector data permitted to reuse by inhibiting information, whose reuse is inhibited or which should not unnecessarily be manipulated from the viewpoint of copyright protection, from being provided to a third party as vector data. An image reading unit (110) inputs image information. A data processing device (115) generates vector data. The data processing device (115) determines whether reuse of the vector data is permitted or inhibited. When it is determined that reuse of the vector data is inhibited, the stored vector data is discarded.

Image processing system and image processing method

Publication number: 20060010115

Abstract: This invention provides an image processing system and image processing method which can promote efficient use of a memory by vectorizing all data of a representative object and, for the same or similar object, referring to the vectorized representative object and using difference data and also convert the same or similar objects at once by editing only the representative object. Input image information is vectorized. The vector data of a representative object is stored. Identity between a target object and the representative object is determined. If the two objects are identical, property information containing information about the reference destination of the vector data of the representative object is stored in place of the vector data of the target object.

ID registration method for tire air pressure sensor, ID registration system, tire air pressure monitoring system, tire air pressure sensor, and smart control system

Patent number: 6967570

Abstract: Provided is a tire air pressure monitoring system in which identification (“ID”) registration is automatically made while specifying a tire position to reduce the manpower of the registration operation and further to prevent mistaken registration. In this system, when an ignition switch is changed from an OFF state to an ON state to satisfy a tire position detection condition, a command is issued to a smart control unit so that a transmitter transmits an ID transmission request to an air pressure sensor, and the air pressure sensor returns ID data as a reply to the ID transmission request. The ID data received is collated with a previously registered ID and, if the result of the collation shows that the ID data pertains to the air pressure sensor of his/her own vehicle, the received ID data is registered as an ID related to a specific tire position.

Tire condition monitoring system

Publication number: 20050151634

Abstract: A tire condition monitoring system is composed of a detector installed in each tire, a transmitter positioned in the vicinity of each tire, and a monitor communicating with the transmitters and the detectors. An initiation signal for initiating operation of the detector is wirelessly sent from the transmitter to the detector, using a low frequency, and the pressure and temperature data detected by the detector are wirelessly sent to the monitor, using a radio frequency. A vehicle identification code differentiating the vehicle from other vehicles may be included in the initiation signal to avoid confusion with signals wirelessly sent from other vehicles. The detector is operated only when the tire condition data from that detector are required to minimize power consumption in the detector.

Image processing system and image processing method

Publication number: 20050123209

Abstract: There are provided an image processing system and image processing method which can appropriately set whether to convert an original paper document into re-usable vector data before obtaining vector data from the paper document. An image scanning unit (110) scans a document to obtain image information, and a storage device (111) stores the image information. A data processing device (115) detects control information appended to the document from the image information and determines whether vectorization of the image information is permitted or inhibited. If the data processing device (115) determines that vectorization is permitted, it converts the image information into vector data; otherwise, it directly stores the image information in the storage device (111).
