Abstract: The vibrating device (1) is mounted in a portable object, such as a wristwatch, to act in particular as a silent alarm. The device includes a moving mass (3a, 3b, 6, 15) formed in part by a magnetic structure connected to a fixed structure (5) via a spring element (4), and a coil (2) connected to the fixed structure without any mechanical contact with the moving mass. The coil is electro-magnetically coupled to the moving mass to enable it to oscillate in at least one direction of oscillation (X) when it is being powered by alternating electrical signals at a determined frequency. A fixed part of the vibrating device includes a part (4d) forming part of the spring element, which is mounted on the fixed structure. This part includes a longitudinal aperture (14) in the direction of oscillation combined with a surface of the fixed structure to define guide means in which a projecting element (16) of the moving mass is placed.

Abstract: The position and the weight of a person, in particular a person on a motor vehicle seat, is determined. Reflectors are used to reflect electromagnetic radiation from a transceiver. The attenuation of the sensor reflector radiation enables a report on the seat position of a person in the radiation path. An antenna of each sensor reflector is connected to an electrical load assigned thereto, which is dependent on the weight of the person acting upon it. Depending on this weight, weight information about the person is superimposed by the load onto the reflected sensor reflector signal. The reflected sensor reflector signal is received by the transceiver and fed to the evaluation unit after a signal pre-processing, which enables the weight information of the person to be evaluated.

Abstract: A watch design that has a movable case that keeps the face of the watch visible regardless of the position of the wrist. In this way, a user can quickly see the watch face in the proper orientation so that the time can be quickly and correctly determined. There are several ways to accomplish this. The case can be mounted on a turntable that rotates on the y-axis. A frame containing the watch mechanism and display is hinged on said turntable and rotated vertically upon the x-axis described by the hinge-mounted frame mounted on said frame. Another embodiment uses a gimbaled point on which the face is free to rotate, much like a compass. In this embodiment, the watch case is weighted to that the face always moves to a readable position. Finally, the watch may include displays mounted in the link of a watchband.

The train wheel is disposed between the mechanical energy storage section and the pointers, and transmits energy from the mechanical energy storage section to the pointers. The power generator has a rotating rotor connected to the train wheel, and generates electric power upon receiving the energy from the mechanical energy storage section. The control section is energized by the electric power produced by the power generator, and controls the rotation cycle of the rotor.

Abstract: A mechanical world timepiece having a transmission mechanism which allows the time display, such as, for example, a 12-hour hand and/or a 24-hour hand, to be directly adjusted with a turning ring having 24 time zones. The timepiece serves for the easily manageable adjustment of the time zone and the reading of the time in a different time zone. Operation could not be simpler. After a lever has been opened, the mechanism in FIG. 1 automatically engages. The gear rim (6), which is fixed with the turning ring, drives a vertical drive wheel (5), which is connected by a shaft to a clutch wheel (4). Once the pinion (4) is engaged, it drives one or two minute wheels (8, 9), which move a 12-hour wheel (10) and a 24-hour wheel (11) in a 1 h-cycle. The turning ring is thus easily turned to the desired destination at 12 h and the local time can immediately be read. Either the turning ring is now turned back to its original locality or the lever is simply closed.
