A lock () for security devices, such as banknote dispensers, to limit access to a confined space () within the device. A remote computer () exclusively controls opening of the lock (). A plurality of the devices may form a network controlled by the remote computer ().

Device for limiting access to a confined space

Device for controlling a locking system, of the type including a bolt ( ) intended to restrict access to a confined space and comprising an electric power supply, a clock formed of a time base and a counter, to define a time reference, an electronic circuit including a microprocessor and a memory ( ); and a key board for entering commands and data, particularly with the purpose of controlling the opening of the bolt. In order to avoid any manipulation of data relating to the intervention dates, the counter includes an incrementation input exclusively connected to the time base. In this way, the information recorded in the counter is only incremented by the time base and cannot be modified by a person.

The invention relates to a dynamically controlled electronic locking system. The locking system includes apparatus ( ) for entering data into the locking system, an electronic data processing circuit ( ) and a locking and unlocking control system ( ). The locking system electronics include, in a particularly advantageous manner, linear feed shift registers for processing the values allowing access to be assured to a protected space. Application to protection systems for confined spaces to which access has to be controlled.

Dynamically controlled electronic locking system and control system fitted with such a locking system

A tamper resistant electronic lock includes an internal tamper protection circuit and monitoring arrangement that thermally couples a transient voltage suppressor and a resettable fuse of the protection circuit to allow thermal feedback or interaction between the components and to substantially prevent overheating due to the application of overvoltage or out of tolerance current condition applied in an attempt to open the lock for unauthorized access purposes. A thermocouple is used to thermally couple the transient voltage suppressor and the resettable fuse, which acts to limit the current to a safe level when the transient voltage suppressor heats up upon application of the overvoltage or out of tolerance current conditions.

A programmable time lock includes a microprocessor, which senses the angular position of a key shaft via a sensor/encoder. The microprocessor includes ROM and RAM memory circuits, a timer, and a clock, and it can activate a stepper motor to control the position of a detent pin. The microprocessor is also connected to a display, which has fields for hours, minutes and seconds, as well as for the days of the week, for a cursor for each day, and for a low-power indicator. System time, as well as opening times for the lock may be set and changed simply by turning the key according to predefined routines. A method for operating the lock includes sets of steps for each of several routines: setting real time, setting opening times for each selected day of the week, and specialty routines including adding an intermediate opening time, cancelling the opening time for selected days, adjusting the system time, for example to change to or from daylight savings time, and verifying the version of the time lock in use. For all routines, the user first arms the lock by turning the key, and then selects a routine and enters the desired parameters by turning the key either continuously clockwise or counter-clockwise (to increment or decrement times or days) or by turning it back and forth to switch routines. In most routines, leaving the key stationary is used to signal acceptance of entered data.
