A mobile transceiver and a method of detecting movement of the mobile transceiver in a radio system. The radio system includes at least one base station and terminals. The movement of the mobile transceiver is measured by at least one acceleration sensor (114 116) to take the movement of the mobile transceiver onto account in the operation of the radio system.

The invention concerns the structure of a timepiece movement, more particularly the structure of the hour wheel (1), the inside of whose pipe (4) includes an annular bulge (6) co-operating with an annular groove (22) arranged on the outer wall of the pipe (21) of the cannon-pinion (7). Thus, the hour wheel is snap-fitted onto the movement, without it being necessary to provide an additional part for this purpose, and its toothed wheel (3) cannot therefore be released from the motion-work pinion ...

A timepiece movement has a case in which are mounted a driving motor, a gear train driven by the motor, a printed circuit board having a driving circuit for driving the motor, and a battery accommodating portion for replaceably receiving a battery. A pair of battery contacts for electrically connecting the battery to the printed circuit board are provided on the outer surface of the case. One end of each of the battery contacts extends through an opening in the case to make elastic contact with ...

A motion sensor comprises a beam having a level switch mounted thereon in a horizontal position. When the sensor is moved, the beam tilts causing the level switch to activate an alarm or remote device. Also in response to tilting, a motor is energized to move the beam back to its original horizontal position. In a first embodiment, two level switches control one motor. In a second embodiment, one level switch controls two motors. In other embodiments, pendulum type switches are employed.

Sensing means for speed and direction of movement of a body (10) movable in an ambient fluid in a direction transverse to the longitudinal axis (11). A central chamber (16) has a plurality of radial bores (15) extending to the outer surfaces (12) and opening at their outer ends to the ambient fluid so that as the body (10) moves, a pressure differential between the inner ends (18) and the outer ends (17) causes fluid flow in the passages (15). Flow sensing means comprises a sound source and soun...

An alternative form of accelerometer is described herein in which an acceleration sensitive element (68, 69) is coupled to a deformable reflector (60) in a lasing cavity (58) to vary the radius of curvature of the reflector in response to experienced acceleration and hence to alter the beat frequency between two transverse lasing modes in the cavity to provide an output signal indicative of the acceleration.

A watch movement having a frame comprising a bottom plate with a peripheral rim portion, a dial secured to said rim portion, and a holding plate disposed between the bottom plate and the dial is described, wherein the holding plate is made of a thin sheet of material and includes one or more positioning elements cooperating with the bottom plate and one or more raised support tongues cooperating with the dial.

A motion detector for protecting items such as loaded trucks such as when parked in warehousing facilities which includes a transmitter affixed to the truck and which includes a tamperproof switch actuated by the truck frame or other portion such that if the truck is moved a given distance from its parked position or if the transmitter is removed from the truck an alarm will sound at a remote position which continuously monitors the output of the transmitter. The central monitoring position may ...

A walker having wheels rotatably supported for orientation in any direction includes a flexible shaft for coupling rotation of the wheel to a tachogenerator in a supporting column that also carries an electronics cabinet including a relay that turns a tape recorder therein on when the wheel rotates, and off when the wheel is stationary. The electronics cabinet also includes a loudspeaker that reproduces the audible messages recorded on the tape recorder when the tape recorder is turned on.

A movement mechanism comprises a substantially spherical holder and a substantially bowl-shaped ring, which, when inserted into each other, are rotatable relative to each other about at least one first axis (A), which lies in a plane which is substantially parallel with the top face of the holder. Driving means are provided for enabling movement of the holder relative to the ring. These driving means comprise a non-straight driving rod bearing-mounted in the holder and means for activating the d...
