Abstract: A data transmitting/receiving system is configured so as to send data to an analog-type watch, without the need to make direct electrical contact thereto and without influencing the drive of the hands of the watch. When a timing signal that is sent from the watch is received, a data transmitting unit performs transmission. The watch does not receive data at other times, and this receiving operation is performed intermittently.

Abstract: In a power feeding apparatus A1, a drive circuit 11 receives electrical power supplied from a power supply 10 and generates a driving signal V. In response to this, an actuator 12 vibrates, and this vibration is transmitted through vibration transmission members 14 and 20 to a converter 21 of a power receiving apparatus B1. The converter 21 includes a piezoelectric device. Accordingly, vibration is converted into voltage, thus generating an electromotive voltage Vg. The electromotive voltage Vg is rectified by a rectification circuit 23, and a large-capacitance capacitor 24 is charged with rectified voltage. A clock circuit 25 receives power from the large-capacitance capacitor 24 and measures time.

The mobile computing device/appliance includes a user interface that includes software mechanisms for enabling watchface orientation in either of: circular and elliptical modes, and further to enable the further display of textual content in remaining portions of the display when in either circular and elliptical mode.

Abstract: A radio-controlled timepiece is controlled by time telegrams emitted by a regional transmitter. When the timepiece is out of the effective range of the regional transmitter, the timepiece is controlled by a local (i.e., close-range) transmitter which transmits time telegrams that have the same frequency and encoding as the time telegrams from the regional transmitter. The local transmitter receives time information from a remote source, such as navigational satellites, or alternatively a time server by way of the internet, in order to create the local time telegrams.

Abstract: A wristwatch (1) whose wristband (6) is attached to a support (3) with respect to which the case (2) can be reversed in the longitudinal direction to show one or other of its faces (16, 17). The case has a pointed profile at its ends, its faces (16, 17) having convex profiles, which are preferably similar. The bottom (4) of the support (3) is concave so as to have a substantially complementary profile to those of the faces of the case. Further, the lateral flanges (7) of the support have substantially the same convex profile, so that the case and the support are substantially flush with each other over the entire length of the case, thus giving a fluid attractive appearance to the watch and to the reversing movement of the case.

Abstract: A mechanical timepiece has a mainspring for generating a rotational force and a front train wheel for undergoing rotation in accordance with a rotational force generated by the mainspring. An escapement/speed-control device for controlling rotation of the front train wheel has a balance with hairspring for undergoing reciprocal rotational movement, an escape wheel and pinion for undergoing rotation in accordance with rotation of the front train wheel, and a pallet fork for controlling rotation of the escape wheel and pinion in accordance with rotation of the balance with hairspring. A switch mechanism outputs an ON signal when a rotation angle of the balance with hairspring becomes a predetermined threshold angle or greater and outputs an OFF signal when the rotation angle of the balance with hairspring does not exceed the predetermined threshold angle. A position-detecting device detects a position of the mechanical timepiece.

Abstract: In a display device, a light ray transmitted through an area which varies a polarization axis, and a light ray transmitted through an area which does not vary the polarization axis, respectively, become a linearly polarized light component (a first returning light ray) which is a specularly reflected from a specular reflecting element, and transmitted through a second polarization separator, a polarization changing element, and a first polarization separator, and a linearly polarized light component (a second returning light ray) which is specularly reflected by the second polarization separator, and transmitted through the polarization changing element and the first polarization separator. The first and second returning light rays present a background portion and a segment portion in a bright display. Both the first returning light ray and the second returning light ray are specularly reflected, presenting both the background portion and the segment portion in a mirror-like fashion.

Abstract: A locking timer assembly for controlling access time for a television, video game, or computer, employs a lockable enclosure box that attaches onto a wall outlet in place of the usual face plate. The volume inside the box encloses a standard 24-hour on-off timer. The box attaches to the outlet by the usual single screw. The cordset for the controlled device plugs into the timer, and then the cord exits the enclosure via a passage, such as a slit, but the slit does not permit passage of the plug. As an added safety feature, there can be a quick-disconnect plunger so that the timer device can be forced out (e.g., by wedge action) from the associated wall outlet. The plunger has a head portion extending outside the enclosure, and can be pushed in using the fingers. Once this is done, the timer cannot be plugged back in until the enclosure is unlocked and opened.
