Title: A lock system
Inventor: OLENFALK BENGT
IPC: E05B49/00
Filed: 1984-03-30
Granted: 1988-07-07
Abstract: The invention relates to a lock system for rooms which are to be made exclusively accessible to different uses over different periods of time, for example hotel rooms. The keys of the system comprise magnetic cards which are provided with magnetically registered data, which for each card includes lock-identification data valid for a given lock or a given group of locks, a validity time expressed in real time and a randomly selected legitimacy code. Each lock includes an electrically actuable lock mechanism (4), a magnetic-card reader (3), a memory (6) for the storage of data, a real-time clock (7), a programming unit (10), a legitimacy comparator (8), and a time comparator (9). The memory (6) has stored therein the lock-identification data valid for the lock. When a magnetic card is introduced for the first time into the card reader (3) of a lock, the legitimacy comparator (8) compares the lock-identification data registered on the card with the lock-identification data stored in the memory (6), and the time comparator (9) compares the validity time registered on the card with the real time given by the real-time clock (7). If these comparisons show agreement, the lock opens and the programming unit (10) is instructed to store into the memory the validity time and the legitimacy code registered on the card. When a magnetic card is later introduced to the card reader (3) the time comparator compares the real time given by the real-time clock (7) with the validity time in the card data stored in the memory and the legitimacy comparator (8) compares the data registered on the card with the data stored in the memory (6) of the lock, and the lock is opened when agreement is found between the data compared. If the comparison made by the time comparator (9) show disagreement, the time comparator compares the validity time registered on the card with the real time given by the real-time clock (7) and the legitimacy comparator (8) compares the lock-identification data registered on the card with the lock-identification data stored in the memory and, if these comparisons show agreement, the lock is opened and the programming unit (10) is used to replace the card data already stored in the memory (6) with the data registered on the card.

Abstract: Seizable, connection-associated switching devices of various types emit processing requests with different urgency degrees to a central sequential logic system for information which are to be processed with different urgency dependent on type. A limit value which may be set in an occupation rejection device based on the measure of a continuously-measured, momentary sequential logic system load serves as a comparison normal and effects that processing requests are rejected (accepted) when the urgency value is lower than (greater than) the limit value. In accordance with the constant, type-associated residual acceptance value stored in the request rejection device for each of the various types of processing requests, a respective rejection character is assigned in cyclical succession to a plurality of processing requests corresponding in number to a respective cycle via the urgency value of the respective processing requests of the appertaining type when the critical limit value is exceeded, being respectively assigned to all but one of these processing requests, whereby this one processing request has an acceptance character assigned thereto.
