Abstract: A smaller sized flip dot display utilizes a magnetically actuated pixel that rotates between two orientations. The orientations display two different optical states. A simulated dot matrix design improves the aesthetics and consumer appeal, and also permits a flip dot display capable of producing a positive contrast display image with darker colored “ON” pixels contrasting with brighter background and “OFF” pixels by reducing the visibility of the spacing gap between each rotating pixel and the surrounding background. An interwoven configuration of magnetic actuators with a coil around each arm of a U-shaped core may result in lower power consumption, low production cost, and small size required for use in consumer and small mobile devices such as watches and mobile phones.

Abstract: A direction indicator system includes: an electromagnetic drive actuator that has a moving part that can slide back and forth, side to side, and diagonally; and a drive controlling unit that controls the sliding direction of the moving part, based on direction indicating information that is supplied from the outside.
Abstract: The traphouse safety flag is an electromechanical safety device mounted at the roofline of a traphouse intended to replace the traditional safety cone or cloth flag that is commonly used to indicate to the shooters that the traphouse is occupied and shooting cannot commence. A “no flag” detent position energizes the normal trap shooting control mechanism while indicating to the shooters that the traphouse and personnel are secure. The safety flag obscures the entrance to the traphouse in a shooting position and if the flag is moved out of the no flag detent position for any reason, the trap shooting control mechanism is deactivated and will not accept a launch command from the shooter.
Abstract: The present invention is a method and apparatus for showing special characters or figures on a rotating disk. A sensor (e.g. spectrum sensor, metal sensor, magnetic field sensor, mechanical contact sensor and sound sensor) and a plurality of light fittings (e.g. bulbs, light-emitting diodes) are fitted to the rotating disk. The sensor detects the surroundings with inconsistency so that different sensed signals at different points are created when the sensor turns around the central axis once. By deciding the fixing points of the repetitive signals, the rotational cycle of the rotating disk is obtained. After analyzing the rotational cycle, different light fittings on the rotating disk light up at different delay time point. In cooperation with the persistency of vision of human eyes, the preset complicate figures and characters are therefore shown on the displaying surface of the rotating disk when it rotates.
Abstract: A miniature telltale module which combines a plurality of telltale functions into one unit and provides reduced cost per function. The module uses a miniature rotary actuator or driver, an image disc having a series of interconnected images or icons and a single light source. The actuator or driver allows a wide tolerances at the inputs while still precisely selecting the image positions. The module includes a light absorbing shield disposed about a light source and having a light opening positioned and sized to provide illumination of the icon, containment of light not directed through the light opening, and control of the angle of light emitted from the opening.
