    摘要: The present invention provides a lock with an authenticated open and set function, by which the lock may be opened without any bothersome operation for inserting a key to open the lock. An IC card 3 sends user identification information stored in a memory 34 to an authenticated open and set function unit 1. The authenticated open and set function unit 1 sends the user identification information to a collator 15 under the control of a controller 11 on reception of it. The collator 15 collates the user identification information sent from the IC card 3 with that stored in a memory 16. When both of the user identification information are coincided with each other, the collator 15 sends the collation signal, which is indicative of the user being authenticated, to the controller 11. The controller 11 gives a controller 17 a command to open a lock installed in a door 2. The controller 17 opens the lock based on the command by the controller 11.

    摘要: This invention reduces electric power consumption of a CDMA communication system receiver while it is in the wait mode. A received spread spectrum signal is demodulated in multiplication means into baseband signals Ri and Rq, and inputted into a complex matched filter. This filter is intermittently driven by supply voltage control means to perform acquisition of received signals. When an electric power calculation circuit detects the output of the filter to reach a peak equal to or greater than a predetermined value, the received signals undergo acquisition by controlling n number of correlators 26-1 to 26-n to work by a correlator controlling circuit. Moreover, de-spreading is performed. The outputs from each correlator 46-1 to 26-n are given to a RAKE combiner and demodulated by the RAKE by a combining and demodulating circuit.

    摘要: An stable inverted amplifying circuit includes an odd number of CMOS inverters and a feedback capacitance. Balancing resistances decrease the inverter open gain and limit the gain of the entire circuit. Serial capacitances act to prevent low-frequency oscillation. Oscillation-preventing circuits are also provided to reduce high-frequency oscillation. Sleep, refresh, and sleep-refresh switches are used to cancel residual loads and reduce power consumption.

    摘要: A fast spread spectrum communication system is provided, having fewer circuits and requiring fewer PN codes to be assigned to a user. A series of digital data to be transmitted, is divided into 4-bit frames. The 4-bit data of each frame is divided into the first through fourth elements in a predetermined order. The first complex number is constructed by the first and second elements, and the second complex number is determined according to the value of the third and fourth elements. The spectrum of the data to be transmitted is spread by multiplying these complex numbers. Four matched filters despread a received signal by different combinations of PN codes stored in a receiver. The first through fourth elements are recovered according to the outputs of the matched filters.

    摘要: A matched filter with reduced electric power consumption is disclosed. The matched filter circuit power consumption is reduced by stopping the electric power supply to an unnecessary circuit since input signal is partially sampled just after an acquisition. Since the spreading code is 1 bit data string, the input signal sampled and held is branched out into the signal groups "1" and "-1" by a multiplexer. The signals in each groups are added in parallel by a capacitive coupling, and the electric power is supplied in the circuit intermittently.
