  • Patent number: 8847897
    Abstract: The touch-operating input device is configured so that when the control circuit turns on the main light source corresponding to each of the translucent operation buttons that can be operated, the control circuit, on condition that the translucent operation button corresponding to the main light source that is turned on is operated, turns off the sub-light source corresponding to the translucent operation button that is turned on simultaneously with the main light source. Ease of operation is increased by enabling the operator to distinguish operated translucent operation buttons from translucent operation buttons that have not been operated according to whether or not the main light sources are lit.

    Abstract: An indicating instrument for a vehicle has a display board, a light modulation member disposed to cover a surface of the display board. An illumination intensity of the display board is detected by a light detecting member and a control unit applies to a dc pulse voltage to the light modulation member, to thereby control a light transmissivity of the light modulation member according to the illumination intensity. When the illumination intensity is higher than a predetermined level, the voltage is applied in one direction so that the light modulation member changes from a colorless condition to a colored condition to restrict an external light from reflecting on the display board. When the illumination intensity is lower than a predetermined level, the voltage is applied in a reverse direction so that the light modulation member is transferred from the colored condition to the colorless condition to maintain the visibility of the display board.

  • Patent number: 7190268
    Abstract: An indicator apparatus facilitates visibility of one or more indicators from multiple angles. The apparatus includes a housing having an outer sidewall portion. The sidewall portion, for example, has a first side extending between two adjacent sides. One or more elongated slots are formed in the sidewall portion. A substantially translucent material is disposed in the slot so that the translucent material is visible from more than one side of the housing, such as the first side and another side through which the slot extends. A light source is operatively associated with the substantially translucent material for illuminating the material. As a result, when the light source illuminates the substantially translucent material, the illuminated translucent material is visible from more than one side of the housing.

  • Patent number: 7161495
    Abstract: The present invention is an apparatus for indicating valid data in a removable memory media. In an embodiment of the invention, an alert may be employed with the removable media, such as NVRAM, to indicate that the battery backup is functional and that the memory content may be valid. One type of alert may be a blinking light source, such as a blinking light emitting diode (LED). In a another aspect of the present invention, contents of an appliance, such as a computer or storage controller, may be arranged so that an alert employed on the removable memory media in accordance with the present invention may be visible to an administrator without opening the chassis of the appliance.

  • Patent number: 7076276
    Abstract: Mobile phones use light signaling or vibrational effects to silently indicate to a user that e.g. a telephone call is incoming. The present invention provides a method, a component for generating vibrational effects combined with light effects and a mobile device implementing this component. The generation of the light effects is obtained from at least one light emitter (200, 201) having at least one light path (300), wherein said at least one light emitter (200, 201) is disposed relative to said mass (100) such that said mass (100) periodically blocks said light path (300) while moving, for generating light effects.

  • Patent number: 7012544
    Abstract: Sign 1 has frame 13 attaching to base 9 and supporting character plates 4. Casing 11 attaches to frame 13 and holds character plates 4 against frame 13. Light assembly 15 and base 9 backlight character plates 4. Backlight is diffusion chamber 17 sidelit by light assembly 15. Casing 11 hides access to the mount and is not easily removable. Light assembly 15 is externally powered and is activated by external messages and by low ambient light. An Emergency Alarm message causes flashing in one colour and intermittent activation of sound. For non-emergency, alternate light mode is used with constant sound. Transmitter 1501 transmits messages for the sign 1. The transmitter 1501 learns emergency telephone numbers for dial detection on a telephone line, in addition to standard emergency telephone number. Emergency button 1507 can begin transmission of emergency alarm message. Transmitter 1501 may have other alarm inputs.

  • Publication number: 20030020627
    Abstract: A warning lamp, provides multi status indication by being illuminated in selected ones of a plurality of colors or by flashing a selected color or colors sequentially. The lamp has a pair of printed circuit boards disposed, one in a base and another upstanding from the base along a central axis, extending midway through the upstanding board. Around the upstanding board and coaxial therewith is a lens which is mounted in assembled relationship with the boards and the base. The upstanding board has arrays of light emitting diodes (LEDs), disposed along spaced lines which are parallel to the axis. The LEDs along different lines provide light of different color, for example, red, green and amber. The printed circuit boards provide a subassembly in which the bottom portion of the upstanding board and the other board are contained in a plastic casting disposed in a recess in the base.

  • Publication number: 20020194756
    Abstract: The signal device includes a housing containing a light and having a front face adapted to receive, in removably mounted engagement thereon, a first message screen selected from a group of message screens. Each message screen of the group of message screens is preferably a substantially planar sheet permitting the passage of light therethrough when mounted in the front face and backlit by the light. The first message screen has a first distress message formed thereon which is illuminated when the message screen is backlit by the light. Each message screen of the group of message screens has a different distress message for communication by the backlighting by the light so that a user may select an appropriate distress message by selecting the corresponding message screen for mounting onto the front face. The light is activated by a switch mounted to the housing and cooperating with a power supply.

  • Publication number: 20020154031
    Abstract: An indicator controller (18), an optical assembly (10) having the indicator controller (10), a traffic light system that comprises at least one of the optical assembly (10) and a method for fault indication by the indicator controller (10) is disclosed. A control signal from a control signal generator (20) of the indicator controller (18) is disabled to block off current supply to a diode chain of three light emitting diodes (LEDs) of an array (12) of LEDs. Input to the control signal generator (20) has a frequency setting section that sets the control signal at a predetermined frequency. Consequently, the three LEDs are made to blink according to the predetermined frequency. The control signal is generated when the amplitude of current supply to the array (12) exceeds a threshold setting.

  • Publication number: 20020149494
    Abstract: A LED symbol signal with LEDs arrayed to correspond to a desired symbol. Light from the LEDs is directed onto corresponding optical segments of a multiple collimating zone element and directed into a forward direction/distribution. A mask defines the desired symbol. The optical segments and or a diffusion surface on the cover or multiple collimating zone element(s) diffuses the display aspect, obscuring the individual LEDs. A diameter of the optical features of the diffusion surface is smaller than a diameter of the optical segments. The LED symbol signal may be configured for retrofitting into an incandescent lamp signal housing.
