Abstract: PURPOSE:To transmit and receive data forth and back between a multiplex transmission system and a control system for decentralized processing by inputting the control data of a transmit signal received by terminal equipment through a signal line and controlling a load wen the address data of the transmit signal coincides with the characteristic address data of the terminal equipmen, and performing proper processing continuously. CONSTITUTION:When the transmit signal Vs is sent from the central control and monitor device of a time-division multiplex transmission system and a terminal block is accessed, a control data signal SD is inputted and control data of respective bits are outputted from control data terminals O1-On successively to generate final control data. At this time, i.e. when all control data are set up, an address coincidence signal is generated at a terminal DRD and inverted by an inverter IN1. Therefore, both inputs of a NOR gate NOR1 falls to ''L'' and its output is inverted to ''H'' to send a latch trigger to a latch circuit 15, which latches the control data. Simultaneously, data latched in a latch circuit 16 previously are inputted to the material block 10 through monitor input terminals I1-In and sent back as a transmit signal to the central control and monitor device through a signal line 3.

IPC: A61B5/0245
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To enable identification of a living body each time biological signals are detected, based on the characteristic value extracted from a plurality of detected signals and the memorized values in the memory means. SOLUTION: This apparatus irradiates light from a light source 2 to a finger 1 each time a plurality of predetermined signals is detected.

Unnecessary noises are eliminated from the signal by a filter circuit 4 and the resulting signal is converted to a digital signal by an A/D converter 5. The digitized pulse wave signal is subjected to extraction of characteristic values by a characteristics-extracting means 6. A data processing means 7 constitutes characteristic vectors and matrices from these values. On collation, a switch 8 is connected to a collation side. Unknown characteristic vectors and wave shape vectors of an examinee enter a comparison/judge means 9 from the data processing means 7.  Thus, each time a pulse wave signal is detected on inspection of a plurality of predetermined items, the signal is collated with registered data in the data storage means for judgement.
