Abstract: A solar-powered LCD device, e.g., for a clock, includes a solar cell arrangement and a liquid crystal display. The solar cell arrangement includes an at least partially transparent carrier and at least one solar cell provided with at least one at least partially transparent contact, at least one first polarizer, a first at least partially transparent carrier, a first at least partially transparent contact, a liquid crystal, a second transparent contact, a second transparent carrier, a second polarizer, and a reflector in a stacked arrangement. The carrier of the solar cell arrangement is one of the carriers of the liquid crystal display.

Abstract: The invention relates to a method and device for setting a calendar work of a watch, particularly of a radio-controlled clock, after changing the battery. The inventive method comprises the following steps: a. determining if the battery needs to be changed; b. bringing the calendar work into a predetermined reference position; c. determining if the battery has been changed; d. determining the actual date to be set on the calendar work, and; e. setting the determined date on the calendar work starting from the reference position. In order to able to carry out this method, a device having the following individual components is required: a. means for determining if the battery needs to be changed; b. means for bringing the calendar work into a predetermined reference position; c. means for determining if the battery has been changed; d. means for determining the actual date to be set on the calendar work, and; e. means for setting the determined date on the calendar work starting from the reference position.

Abstract: The radio-controlled wristwatch comprises a memory unit (30) in which a table of more than four time signal transmitters (1 . . . 10) from more than two time zones (A . . . N) is stored. Attempts for receiving from the transmitters (1 . . . 10) filed in the table are made by a control device (28), and upon a successful reception of a time signal transmitter (1 . . . 10) from the table, the appurtenant time is displayed upon the display (32) of the wristwatch (20).

Abstract: A wristwatch is converted into an emergency call device by unscrewing a rear cover from the back of the wristwatch housing and screwing in a transmitter housing that carries a signal-emitting mechanism.

Abstract: An emergency call transmitter includes a housing formed by a substantially hollow cylindrical center piece which defines first and second opposite sides. A flange part is arranged on the first side, and a base part is arranged on the second side. At least one antenna wire passage is formed which leads out of an interior of the center piece. Disposed in the housing are an electric circuit element and a power supply device. An antenna wire is disposed in the housing and is arranged to be pulled out of the housing through the antenna wire passage. The antenna wire is formed of a memory material which aligns itself to a linear state once pulled from the housing.

Abstract: A radio-controlled wristwatch includes a casing. A central portion of the casing disposed generally centrally with reference to a longitudinal center axis of the casing is formed of metal at least on the exterior thereof. An antenna core is disposed within a chamber defined by the casing. The antenna core lies on a plane oriented transversely with respect to the longitudinal axis. A spacer ring is disposed in the chamber between the central portion and the antenna core, the spacer ring formed of electrically non-conductive material.
