  • Patent number: 10109435
    Abstract: An interchangeable electrical assembly provides a tactile switch that selectively opens and closes a circuit for operating myriad styles of illumination devices. The tactile switch detachably mates with, and regulates conduction of direct current to the illumination device. The tactile switch also provides tactile feedback of an operating position. A wire carries a 12 volt direct current into a switch housing. A conductive member receives the direct current. A cap receives a force to axially displace the conductive member while providing tactile feedback to the position of the conductive member. A contact pin operatively connects to the conductive member. A spring biases the conductive member to disengage from the contact pin. The cap selectively displaces the conductive member to engage the contact pin. An illumination device detachably mates with tactile switch, and includes a conducting shaft, an inverter for converting direct current to alternating current, and circuitry to generate illumination.

  • Patent number: 9931975
    Abstract: A vehicle lamp control apparatus includes a receiver, a storage, a correction section, and an adjustment instruction section. The receiver receives output values of an acceleration sensor. The storage stores information indicating an ideal positional relationship between sensor-side axes and vehicle-side axes. The correction section plots the output values, obtained during running of a vehicle, on coordinates in which acceleration in a vehicle longitudinal direction is set to a first axis and acceleration in a vehicle lateral/vertical direction is set to a second axis, derives a straight line from plotted points, calculates displacements of the sensor-side and vehicle-side axes from the ideal positional relationship, using an inclination of the straight line, and corrects the information. The adjustment instruction section derives a tilt angle of the vehicle from current acceleration using the corrected information, and generates a control signal to instruct adjustment of an optical axis of a vehicle lamp.
