  • Patent number: 7549390
    Abstract: A gauge with a light transmitting pointer and a light-transmitting dial plate having a surface with indicia for a variable represented by the dial, at least one light source facing a hub of the pointer and positioned rearwardly from the rear surface of the dial plate for illuminating the dial plate. The light-transmitting pointer is mounted for rotational movement about an axis normal to the dial plate. The pointer hub is concentric with the axis, extending through the dial plate and projecting both forwardly and rearwardly from the plate, and an indicator projecting laterally from the hub across a portion of the front surface of the dial plate. The portion of the hub extending rearwardly of the dial plate is shaped to capture light directly from the light source so that light enters the hub and propagates forwardly through the hub, and then laterally from the hub into the indicator to illuminate the indicator.

  • Patent number: 7520242
    Abstract: The present invention concerns a micromotor for an indicator device comprising a hand of the type generally used in the instrument panels of motor vehicles. More specifically, the present invention concerns a micromotor of this type comprising a case wherein the thickness of one area is smaller than its maximum thickness, so as to form a free space or recess open on the exterior, in particular on the bottom of the case. This recess can be advantageously used for arranging components necessary for the operation of the instrument panel in which the micromotor is mounted, thereby saving space with respect to devices of the prior art.

  • Patent number: 7518498
    Abstract: The meter has a back light illuminating with a predetermined color, a display portion disposed in font of the back light and being changeable between a positive mode and a negative mode at a predetermined state, and a reverse control device determining whether an engine of a vehicle is in an initial starting step or the vehicle is in a running state. The control device reverses the display portion in response to a result of the determination. The control device changes the display portion from one of the positive and negative modes to the other at a lower speed when the control device determines that the vehicle engine is in an initial starting step than when the control device determines that the vehicle is in a running state. When the control device determines that the vehicle engine is in an initial starting step, the control device changes the display portion in one of the positive and negative modes from a neutral contrast state.

    Abstract: A speedometer face plate assembly that incorporates a border of light transmitting segments above the speed indicating numerals is disclosed. Each of the segments is a different color. The colored segments are lighted from behind as the speed changes so that colored light is visible both peripherally and directly to the driver. Each color is associated with a specific speed increment so that once the driver becomes familiar with this speedometer face plate assembly, he or she will be aware of the speed traveled according to the color of the light and will not have to look directly at the speedometer as frequently as is currently necessary. In addition to the colored light transmitting border, there may also be a colored light transmitting section under the numerals or at another area on the speedometer face to further enhance the colored light effect. This speedometer face plate assembly contributes to increasing driving safety.

    Abstract: An illumination device for a display instrument is described which is used to illuminate two sets of scale markings and to separately illuminate a pointer scale of the display instrument. The light from a light source is guided past light funnels that are used to illuminate the pointer scale by an optical waveguide. This provides an efficient and economical means of illuminating a display instrument of this type.

  • Patent number: 7038975
    Abstract: There is provided a type of luminous hand including a part made of moulded transparent material that forms a circular head (28, 35) and a body (28, 34) of a hand. In order to direct a portion of a light beam parallel to the axis (15) of the hand towards the interior of the body, the head includes a plurality of reflectors (40, 41) distributed around the axis and formed by dihedron shaped hollows. This improves the intensity and uniformity of the light in the hand body. Inclined light-diffusing surfaces, covered with a light coloured paint, are arranged on the bottom face of the hand. In a display device with several coaxial hands (11,12) such as that of a watch, the reflectors of the superposed heads (29, 35) of the hands are located at respective distances from the axis which are different from one hand to another, such that they never completely cover each other. The light source preferably includes three light-emitting diodes (23) located under the dial (10).

  • Patent number: 7034495
    Abstract: An output port open control device (65) allows a port (P3) which outputs PWM signals of a Cos+ side to be in a high impedance state in a period in which respective PWM signals of Cos+ and Cos? supplied to a S-phase coil (22) of a stepping motor (2) are in a ground level, induced voltage corresponding to a magnetic flux variation caused in accordance with rotation of a magnet rotor (23) is generated in the S-phase coil (22), a voltage comparator (72) compares the induced voltage with a previously set threshold value and outputs presence or absence of the induced voltage, and a zero-reset judging device (66) determines that a pointer (4) is in the middle of rotation when the induced voltage is detected, and determines that the pointer (4) is in contact with a stopper mechanism (5) when it is not detected.

  • Patent number: 6981464
    Abstract: An illuminated pointer includes an outer pointer that surrounds an inner pointer. The outer pointer extends from a base and is generally elliptical. The inner pointer extends from the base into the void of the outer pointer. The illuminated pointer utilizes a single light source for illuminating both the outer and inner pointer. The inner pointer provides easier reading of a dual scale gauge such as with a speedometer having both English and Metric speed scales.

  • Patent number: 6956351
    Abstract: A driving device, includes a stepping motor having an exciting coil and a rotor; a driven member driven in accordance with a rotation of the rotor; a stopper mechanically stopping the driven member at a zero position; a controller controlling the state of excitation of the exciting coil; an induced voltage detector detecting an induced voltage generated by a change of magnetic flux according to the rotation of the rotor; and a zero position detector detecting a stoppage of the driven member at the zero position. The controller supplies an exciting pattern to the exciting coil at the time of processing of zero position detection. The exciting pattern includes a first exciting step for detecting the induced voltage and a second exciting step for rotation. Total periods of the first exciting step is greater than that of the second exciting step during an electrical angle 90° in the one cycle.
