Abstract: For the process for determining a distance, there is provided a succession of coded signals at high frequency transmitted between a base station and a wearable object. A preparation of a response signal is conducted in the wearable object on reception of the first synchronisation signal after activation of the wearable object. A transmission of successive coded signals at high frequency from the wearable object is conducted for the station, of which the last response signal is scrambled by a modulation of data on the last signal received at a high transfer rate from the station. An analysis is conducted in a processing unit of the base station after reception of the signals from the wearable object to accurately determine the distance separating the base station from the recognised wearable object.

Abstract: In the case of the process for secure access to a determined space, it is provided that after activation of the wearable object, a first coded signal is transmitted from the access or unlocking device, this first coded signal is received in the object and a coded response signal is transmitted with synchronization to the device after a defined time of transmission. A processing of the coded response signal converted in the processing unit of the device is conducted in order to check the defined time delay and the response code of the wearable object and to determine the flight times of the signals between the device and the wearable object. The distance separating the wearable object and the access or unlocking device is thus calculated to authorize access to the determined space if the calculated distance is below a determined threshold after recognition of the wearable object.

Abstract: The dual-modulus prescaler circuit (1) is devised to operate at a very high frequency. This circuit includes an assembly formed of two dynamic D-type flip flops (12, 13), and two NAND logic gates (15, 16) arranged in negative feedback between the two flip flops. The two flip flops are clocked by an input clock signal (CK) to supply a divided output signal (OUT) whose frequency matches the input clock frequency divided by 2 or by 3 as a function of a division mode selection signal (divb) applied to the input of the first NAND logic gate (15). One non-inverted output of the second flip flop is connected to one input of the first flip flop (12). The first dynamic flip flop includes three active branches and supplies a single inverted output signal. A third flip flop (14) with three active branches receives an inverted mode selection signal (div) at input in order to supply the mode selection signal to the inverted output thereof, clocked by the non-inverted output signal of the second flip flop.
