摘要： A light detecting apparatus has a two-axis deflector such as a two-axis mirror capable of controlling the deflection of a light beam. The apparatus realizes a sure and speedy light beam search operation without increasing deflecting frequencies of the two-axis deflector. In the light detecting apparatus, a digital signal processor (3) generates two periodic signals having different frequencies to separately control deflective operations in two axial directions of the two-axis deflection mirror (1). A light beam from the two-axis deflection mirror (1) draws a locus on a two-dimensional position sensitive detector (2). Along the locus, the search operation is carried out to find an orientation of a light emitting element that emits a light beam toward the two-axis deflection mirror (1).

摘要： A method to reduce the power dissipation of a system by omitting an unnecessary CPU throttling operation in a power management apparatus that performs the CPU throttling operation. A power management apparatus 10 is constituted by an event detecting section 12 to detect an event in a system, an activity detecting section 14 to decide whether the system is in a busy state or in an idle state by checking whether or not there is activity in the system, and a clock control section 16 to execute CPU-clock control. The control section 16 does not perform an unnecessary CPU throttling operation, by stopping the CPU throttling operation when the system is in the idle state and performing the CPU throttling operation only when the system is in the busy state. With this, the power dissipation of the system can be considerably reduced.

摘要： A communication route guidance system provides exchange of data between an information center and each of a plurality of mobile units such as vehicles. The information center has the latest road data and searches it to prepare recommended route guidance data in response to a request from the mobile unit. The reccommended route guidance data is divided into a plurality of data segments, each usable as an independent guidance instruction in the mobile unit. The mobile unit has stored therein road data similar to the road data in the information center and determines if data communication with the information center is available. In a case where the mobile unit can not communicate with the information center, the mobile unit prepares route guidance based on the road data stored in the mobile unit. It thereby becomes possible to guide the user even in the case that the mobile unit can not communicate with the information center. Even in a case where a communication link is disrupted during transmission of route guidance data to the mobile unit, the mobile unit can effectively prepare whole route guidance data in combination with already-received route guidance data and additionally prepared route guidance data by reference to the road data stored in the mobile unit because the already received route guidance data is structured to be usable independently.

摘要： A radar apparatus is provided that can correctly extract the necessary point for a determination related to the safe travel of one's automotive vehicle among objects such as automotive vehicles moving at an angle in front and constructed objects. The radar apparatus of the present invention provides antennas that transmit beams in a plurality of directions and receive the reflected waves from objects as received signals. The objects that generated these reflected waves are detected. In addition, this radar apparatus provides a reflected location detection device that detects the reflected locations that are the generation source of the reflected waves for this plurality of directions, a grouping device that groups each of these detected reflected locations into a group of single or plural reflected locations assuming they belong to the same object, and a device that extracts reflected locations having the shortest distance from the moving body from among these grouped reflected locations to serve as reference points related to the safe travel of this moving body.

摘要： In a communications navigation system, data is transmitted and received between a navigation base apparatus provided at a navigation base and each of a plurality of navigation apparatuses provided in moving bodies such as vehicles using communication. A determining section of the navigation base apparatus determines untraveled route portion by comparing user's information stored in a user information storage with information of a recommended route provided by a route search section. The navigation base apparatus extracts necessary route/guidance information for untraveled route portion determined by the determining section from route/guidance data stored in a database, and then transmits the extracted route/guidance data to the navigation apparatus identified by the identification information. The route/guidance information may be transmitted to the navigation apparatus in the form of segmented data. In this way, it becomes possible for the navigation apparatus to extract only the route/guidance information needed by the user from the route/guidance data stored in the database.
