Abstract: An antenna system for a radio frequency (“RF”) wireless keyboard includes a metallic plate as a part of the antenna system. The metallic plate is located within the wireless keyboard. A RF transmitter is coupled to the metallic plate and an antenna wire which form an the antenna loop. The antenna loop may also be directly integrated into the metallic plate by creating a cut-out space in the metallic plate. The antenna system may also include the metallic plate directly coupled with the RF transmitter so that the metallic plate is a whip or dipole antenna. The RF transmitter generates RF signals associated with particular keyswitches of the wireless keyboard. The antenna system transmits the generated RF signals to a RF receiver that resides separately from, and that communicates with, the wireless keyboard.

Abstract: Portable receiver for receiving and displaying radio broadcast messages having a series of characters, the portable receiver including a housing (6) having at least one face (7); a memory (45) for storing messages; a display (2) mounted on or visible through the face, for displaying the stored messages; and at least one control device (4) including a manually actuable member (200), the control device being adapted to enable manipulation of the stored messages by a rotation applied to the manually actuable member. Control device (4) includes a stem (205) rotatably mounted in housing (6) around its longitudinal axis. Manually actuable member (200) includes a dome-shaped portion (5) at least partially emerging from face (7). Stem (205) is fixedly attached to manually actuable member (200) so that dome-shaped portion (5) is rotatable around the longitudinal axis.

Abstract: Portable device for receiving and/or transmitting radio-transmitted messages comprising:a case (11; 42; 51),an antenna (12; 31, 32; 52, 53) capable of picking up both a magnetic component and an electric component of an electromagnetic field carrying radio-transmitted messages, anda micro-receiver (13) receiving the messages picked up by the antenna, said antenna comprising two conductive plates (15, 16; 31, 32; 52, 53) disposed so as to pick up the radial electric component (E.sub.r) of said electromagnetic field with respect to the body of the wearer.The antenna (12; 31, 32; 52, 53) is formed by a coil (17) comprising a turn arranged in said case (11; 42; 51) to pick up the azimuthal magnetic component (H.sub..PHI.) of said electromagnetic field around said body and the plates (15, 16; 31, 32; 52, 53) form part of said coil (17).

Abstract: A watch (31) comprises an horological movement (32) associated with a liquid crystal display arrangement (34) located under the crystal (8) of such watch. The watch (31) comprises an active display arrangement (36) located within the watch case (4). In addition, the watch comprises a mirror (40) arranged in the back cover (6) of the watch and an enlarging lens (38) arranged under the crystal (8). The optical elements are arranged so that the light coming from the active display arrangement (36) is reflected by the mirror (40) in the direction of the enlarging lens (38).

Abstract: A timepiece includes a timekeeper displaying the hour (4) and the minute (5), a receiver for radio broadcast messages adapted to be read on a display (7) and a control arrangement (2) including a rollerball (1) adapted to be manually rolled in a first direction (Y) for which received messages can be displayed one after the other and in a second direction (X) for which at least the functions of engagement, of disengagement or entry into a special operating mode may be chosen. The rollerball may also be pressed in a third direction (Z) for which the displayed message may at least be erased or protected.

Abstract: The timepiece includes a timekeeper displaying hours (4) and minutes (5), a receiver for radio broadcast messages capable of being read on a display (7) and a control arrangement (3) including a stem fitted into a crown (10). The stem-crown can be brought into three different axial positions, a first stable drawn-out position in which the timekeeper may be set to the time of day by rotation of the crown, a second stable neutral position in which received messages may be displayed one after the other by rotation of the crown and a third pushed-in unstable position in which the displayed message can be erased or protected.

Abstract: A timepiece (4), adapted to be worn on a part of the body, for example on the wrist, is provided with an antenna capable of capturing an electromagnetic field bearing radio-diffused messages. Measurements have shown that when close to the wrist the radial electric component (E.sub.r) and the azimuthal or tangential magnetic component (H.sub..phi.) were predominant. Consequently, in order to capture the first, a capacitive antenna the electrodes of which are parallel to the back cover (2) of the timepiece will be provided and, to capture the second, an inductive antenna including a winding the axis of which is parallel to the longitudinal direction of the bracelet (3) will be provided.
