A control device connected to a non-contact charging device for non-contact charging a portable device and a wireless communication device for communicating with an electronic key to operate an electrical component mounted in a vehicle, includes a memory that stores a wireless communication cycle for communication between the electronic key and the wireless communication device, a wireless communication control signal output part that outputs a wireless communication control signal for controlling operation of the wireless communication device, a non-contact charge control signal output part that outputs a non-contact charge control signal for controlling operation of the non-contact charging device, and a synchronizer that synchronizes the wireless communication control signal and the non-contact charge control signal with each other.

Non-contact charger system, control device, wireless communication device, and non-contact charging device

An information system capable of utilizing information in which a user evaluation pertaining to the environment or conditions surrounding a traveling vehicle is highly precise (very near real time). The information system () comprises an onboard terminal device () for outputting information obtained by a user's input operation, a communication terminal device () for transmitting the information outputted by the onboard terminal device () to the exterior, and an information center () for classifying and delivering the information received from the onboard terminal device (). The onboard terminal device () varies the level of detail of the information that the user is allowed to input in accordance with the speed of the vehicle or the presence/absence of a passenger other than the driver of the vehicle.

Information system and in-vehicle terminal device

An automotive vehicle navigation method includes obtaining electronic textual navigation information and converting the textual navigation information into audio data. The audio data is stored within the vehicle and is played back within the vehicle in sequential increments that correspond to respective legs of a trip being made by the vehicle.

Vehicle navigation playback method

The car navigation file of the optical disk stores data which is used for navigating the car, and the video title set stores a plurality of video titles concerning facilities located in districts included in the map data. A VOB comprising one scene of a video image of a video title is a filmed shot in high picture quality. The VOB includes a writing command that position information of a position associated with the video information be written in the rewitable area when the predetermined operation is performed during the reproduction of the optical disk. When the disk reproduction apparatus executes the writing command, the position information can be written in the rewritable area. Consequently, the user can easily have the destination written in the optical disk, enjoying the filmed shots.

Optical disk and reproduction apparatus for producing optical disk

A magnetic disk device using a pattern in which a plurality of pulse trains functioning as a demodulation start synchronization mark, having one-half a frequency of a clock synchronization PLOSYNC but having mutually different pulse numbers, are dispersedly arranged in pulse trains having the same frequency as that of the clock synchronization PLOSYNC, and also using, as a unit for detecting the demodulation start synchronization mark, a unit which confirms coincidence of the pattern in a time unit of one period of the pulse trains of the clock synchronization PLOSYNC and recognizes the demodulation start synchronization mark by complete coincidence of the demodulation start synchronization mark with the pattern or by coincidence of at least a predetermined number of the demodulation start synchronization marks with the pattern.

Magnetic disk device

A magnetic disk drive apparatus can reduce the production probability of failed sector due to the fact the a decoding start synchronization mark can not be detected in reproduction of data on a magnetic disk and can utilizes the capability of an error correction circuit sufficiently. A plurality of decoding start synchronization marks are provided in each sector of the magnetic disk and when any one of the decoding start synchronization marks can be detected, a decoding circuit can be operated.
