Abstract: A lock (10, 40, 42, 58) for security devices 26, such as banknote dispensers, to limit access to a confined space (32, 34) within the device. A remote computer (28) exclusively controls opening of the lock (10, 40, 42, 58). A plurality of the devices may form a network controlled by the remote computer (28).

Abstract: In order to increase the security of devices (26) for limiting access to a confined spaces (32, 34), such as banknote dispensers, the latter are fitted with locks (40, 42, 58) and a coordination device (54), each lock being connected to said device. The devices together form a network controlled by a computer (28). The computer (28) controls the opening of the lock (40, 42, 58).

Abstract: Device for controlling a locking system, of the type including a bolt (18) 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 (32); 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.

Abstract: The invention relates to a dynamically controlled electronic locking system. The locking system includes apparatus (10) for entering data into the locking system, an electronic data processing circuit (12) and a locking and unlocking control system (14). 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.

Abstract: 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.

Abstract: 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.

Abstract: The device includes at least one sliding bolt in a disengaging mechanism, and at least one movable pin arranged to lock said disengaging mechanism and prevent movement of the bolt. It is mounted in a housing (10) and consists of two identical control modules (11, 12) each having an arm (11a, 12a) which is fast on a lever (13) controlling the movable locking pin (14). Each module is mounted on a base plate (11b, 12b) supporting a mechanical activating device (11c, 12c) and a device for controlling this device and pushing the arm (11a, 12a) by means of a detent pin (11d, 12d). The activating device comprises at least one potential energy storage element while the module comprises a device for arming this element. A programmable electronic timing device and a member coupled thereto are provided for releasing the potential energy at a predetermined time. Each module has an independent power supply from cells or batteries (11e, 12e). A display device (11f, 12f) provides control parameter display.

Abstract: The apparatus comprises a first marking element rigid with a disk rotationally driven in synchronism with the translation movement of the member and a detector which delivers an electrical signal upon the passage of the marking. The disk makes many complete rotations for the complete stroke of the member. A second marking element is rigid with the member and a second detecting device delivers an electrical signal upon the passage of the marking in front of the detector. The logic circuit C processes these two electrical signals so as to produce a signal 10 which gives the instant when the moving member passes through the reference position.

Abstract: For each degree of freedom of the robot and in the COMMAND mode (switch 32 in position II) the corresponding movable member 21 is moved by an actuator 20 in accordance with an error signal formed as the difference between a command datum C supplied from a register 27 and an actual position datum P supplied by a position sensor 26, the command data required from time to time being provided from a memory 28 via a circuit 34. For training the robot, the FOLLOW mode is selected by putting the switch 32 in position I and the command datum C is replaced by the position datum P, the value of which is periodically entered in the register 27 via a switch 33 which is periodically closed by pulses 35a from a pulse generator 36. When the robot is at a position to which it is to be trained, a switch 30 is closed to write the then contents of the register 27 in the memory 28 for subsequent use in the COMMAND mode.

Abstract: A fabrication procedure for crystal resonators in which belted component holders are used, each accomodating the constituent elements of a resonator. When the above-mentioned elements are assembled, the component holders serve the purpose of assembly fixtures. The assembled resonators are retained in the component holders which thus also provide a packaging function for the final products. The component holders have elastically deformable clamps which accomodate the constituent elements of the resonators to be assembled and have support sections which receive the crystal element of each resonator.
