A CATV communication system includes a center and a plurality of terminal devices connected via a CATV net. The center includes: a first transmitter for transmitting upstream channel use information representing unoccupied channel; a first detector for detecting channel get request from data transmitted from the terminal device; a second detector for detecting a presence of the unoccupied channel; a second transmitter for assigning one of the detected unoccupied channels to the terminal device transmitted the channel get request and for transmitting channel assign data including a designation of the assigned channel; and a first communication unit for performing data communication with the terminal device via the assigned channel. The terminal device includes: a second communication unit connected to a computer for performing communication with the computer; a third detector for detecting center-directed data included in the data received from the computer; a fourth detector for detecting the upstream channel use information from the data transmitted; a third transmitter for selecting one of the unoccupied channels on the basis of the upstream channel use information and for transmitting the channel get request designating the selected channel to the center; a fifth detector for detecting the channel assign information; and a third communication unit for performing data communication with the center by using the upstream channel designated by the channel assign information for data transmission.

CATV communication system and method for the internet connection

A biological information detection apparatus including a biological information detection and transmission unit mounted on a steering wheel for detecting and transmitting biological information of an operator of a motor vehicle; a biological information receiver mounted on a steering column that receives biological information detection and transmission unit; and a steering wheel position detector that detects a rotational position of the steering wheel; wherein the biological information detection and transmission unit includes a sensor for detecting biological information and generating a detection signal memory for storing the detection signal from the sensor; a transmitter for transmitting a detection signal from the memory; and a controller for controlling the storage of the detection signal in memory and the transmitting of the detection signal from the transmitter when the steering wheel position detector detects that the steering wheel is in a substantially straight driving position; and the biological information receiver includes a receiver which is mounted in a position whereby a detection signal from the transmitter can be received wirelessly when the steering wheel is in a substantially straight driving position.

Biological information detection apparatus

The living condition of a resident is prehended by a sensor disposed in a room. Identification information and vital information transmitted from a portable transreceiver carried by the resident are monitored. An audio signal favored by the resident is sequentially reproduced while the level is adjusted in accordance with the current living condition and physical condition of the resident.

Audio apparatus

The audio apparatus of the invention has: vital information detecting means for detecting vital information of a resident; a database which is configured by information based on the vital information, and in which at least vital information of the resident is accumulated; audio signal information generating means for, when vital information is detected by the vital information detecting means, referring to the vital information of the database, and for generating predetermined audio signal information at the detection; and audio signal producing means for producing an audio signal to the resident, the audio signal being based on the audio signal information generated by the audio signal information generating means.
