摘要:
A portable one-way radio pager (1) comprising receiving means (4, 5, 6) for receiving radio messages, a memory (8) for storing the messages, a screen (2), a simplified keypad (3) and an electronic CPU (7). The memory comprises a directory (8a) for storing at least the names and telephone numbers of other parties, and the CPU is designed to recognise specific messages known as download messages in order to store the contents of such messages in the directory and display data from the directory on the screen in response to a request from the user.

The invention concerns a traffic information device comprising a portable one-way messaging receiver (10), designed to provide motorists with information concerning running times in a road network, said receiver comprising a keyboard (12) and a screen (11). The receiver memory contains, for each road network section, a starting point, an arrival point and an elementary running time. Moreover, the central unit is adapted to update the elementary running times of the sections on the basis of received radio messages, and to compute and display the global running time between a starting point and an arrival point as required, based on the stored elementary running times.

摘要:
Method for decoding a multivalent electrical signal which can take a number n of states greater than two. An electrical magnitude, representative of the signal state in successive plateau periods (T1, T2, T3... Ti) of constant time T during which the electrical magnitude remains substantially invariable, is successively measured at constant time (T) intervals from an origin time (t0) which is determined by taking close measurements during a synchronization period so as to locate the plateau periods; the origin time is then fixed at half of one of the plateau periods.

An electrostatic relay comprises at least one fixed base having a fixed electrode and an actuator frame having a movable electrode. The fixed base carries a pair of fixed contacts insulated from the fixed electrode. The movable electrode carries a movable contact insulated from the movable electrode. The movable electrode extends along the fixed electrode and is pivotally supported at its one longitudinal end relative to the fixed base so as to pivot between two contacting positions of closing and opening the movable contact to and from the fixed contacts. The movable contact is formed at the other longitudinal end of the movable electrode. A control voltage source is connected across the fixed electrode and the movable electrode to generate a potential difference therebetweeen for developing an electrostatic force by which the movable electrode is attracted toward said fixed electrode to move into one of the two contacting positions. The electrostatic relay is characterized in that the movable electrode is cooperative with the fixed electrode to define therebetween an elongate gap which is narrower toward the one longitudinal end about which the movable electrode pivot than at the other longitudinal end of the movable electrode at which the movable contact is carried.
