  • Patent number: 9229472
    Abstract: An apparatus for providing electric power to a portable computer is disclosed. The apparatus includes a timekeeping circuit, a voltage regulator, a set of battery cells and a controller. The timekeeping circuit includes a clock circuit and a memory for storing a calendar time that is updated based on time information generated by the clock circuit. The battery cells can supply electric power to the voltage regulator, and the voltage regulator is capable of supplying electric power to the timekeeping circuit. When the output voltage from the battery cells exceeds a first voltage threshold, the controller directs the voltage regulator to supply electric power to the timekeeping circuit. When the output voltage from the battery cells drops below the first voltage threshold, the controller directs one of the battery cells to supply electric power to the timekeeping circuit.

  • Patent number: 9182746
    Abstract: A stepping motor control circuit includes: a rotation detection unit that detects a induced signal exceeding a predetermined reference threshold voltage which is generated by a stepping motor in a detection section divided into at least three sections, and detects a rotation state on the basis of a pattern indicating whether the induced signal exceeding a reference threshold voltage is detected in each of the sections; and a control unit that selects a main drive pulse depending on the rotation state detected by the rotation detection unit from a plurality of main drive pulses which are different from each other in energy, and drives the stepping motor. When the induced signal exceeding a reference threshold voltage is not detected in an initial section, the rotation detection unit detects the induced signal by shifting an end position of at least one section other than the initial section to a rear side by a predetermined amount.

  • Patent number: 6717889
    Abstract: A clock has a luminous decoration member provided on a dial of the clock. The luminous decoration member is made of a transparent material and formed in an annular shape having multiple lightings fitted therearound. A layer of fluorescent material is applied on a rear side of the luminous decoration member. Whereby when the lightings are providing light on the luminous decoration member, the fluorescent material applied on the luminous decoration member is lit so as to emit colorful fluorescence to the surroundings thereof. Therefore, a user can easily observe the dial and clock hands of the clock in the dark or night.

  • Patent number: 6697303
    Abstract: With a dial for a timepiece comprising a decoration member 21 having a plurality of through holes 22 formed vertically on a luminescent member 10, the cross-sectional area of lower-side holes 24 of the decoration member 21 is formed to be larger than that of upper-side holes 23. Therefore, even if a substrate is thick, the diameter of the upper-side holes 23 of the through holes 22 can be formed to be small sufficiently. Moreover, compared to a dial size 20 for a timepiece wherein the decoration member 21 is placed on the luminescent member 10, the diameter of the through holes 22 of the decoration member 21 is small. Thus, it is possible to take in enough light from the luminescent member 10 through the lower-side holes 24 to ensure the sufficient amount of light through the through holes 22. It is possible to obtain sufficient illuminance for the dial.

  • Publication number: 20030231553
    Abstract: A wall clock of the analog type with hands for indicating the time includes a battery, a housing, a dial with time indicia disposed in the housing and an illumination module disposed adjacently to the dial. The illumination module has one or more recesses defined in an edge with one or more light sources disposed in the recesses to provide illumination into the module. The illumination module has edges and a back surface with light reflective properties to reflect light in the interior of the module and out the front surface and through the dial to provide night lighting exterior to the clock. Preferably, the module has an ovate shape such that the recesses and light sources are disposed outside of the dial area. A light sensor senses the ambient lighting conditions and activates and deactivates the light source. The starting and ending times for illumination may also be programmed into the clock. A battery icon has a plurality of bars to indicate the remaining battery capacity.

  • Patent number: 6512721
    Abstract: A dial for timepiece is provided which includes a decoration member having a through hole, and a luminescent member disposed under the decoration member. A first surface processed layer is provided on an upper surface of the decoration member, and a second surface processed layer having a light-transmissive property is provided on an upper surface of the luminescent member. When the luminescent member is turned on, light emitted from the luminescent member is transmitted through the second surface processed layer and passes through the through hole of the decoration member. Because the transmitted light illuminates the upper surface side of the decoration member partially in accordance with the through hole, the dial is visible even in a dark place. In addition, decoration effects can be achieved by both the first surface processed layer and the second surface processed layer in accordance with the through hole.

  • Patent number: 6480441
    Abstract: A timekeeping and magnifying device is disclosed. The device includes watch and a magnifying lens pivotally connected to the watch. The lens may be pivoted away from the face of the watch to magnify objects other than the face of the watch. In one embodiment of the invention, the device includes spring structure which is adapted to bias the lens away from the face, and a fastener which selectively retains the lens adjacent the face of the watch until disengaged, at which point the spring structure automatically pivots the lens away from the face of the watch. In a variation of this embodiment, the fastener is actuated by a push-button mechanism. The device may further include a light that is actuated when the lens is pivoted away from the face of the watch, such as by the spring structure.
