  • Patent number: 9794455
    Abstract: An imaging system includes a housing, circuitry within the housing, and a connector coupled to the circuitry and extending from the housing for electrical and mechanical connection with a personal electronic device. The connector can be secured to the housing using a connector support that is resilient and flexible. The connector can be electrically coupled to a main printed circuit board assembly using a flexible circuit. The resilient connector support can be configured to allow movement of the connector relative to the housing. The flexible circuit is configured to maintain electrical connection to the main printed circuit board assembly when the connector moves relative to the housing. The imaging system can be a thermal imaging system and may include an infrared camera core.

  • Patent number: 9347660
    Abstract: A mirror includes a frame holding therein back-to-back mirror plates having different magnification factors, e.g. 1× and 5×, each plate having a central reflective imaging area and a concentric light transmissive window. Continuously rotatable bushings supporting the frame between opposed arms of a yoke enable interchangeable orientation of 1× and 5× mirror plates in a forward-facing use position. A printed circuit board holding a circular ring of alternating yellow and white light emitting diodes (LED's) within the frame between the windows receives electrical power from a power supply in the base of the mirror via novel continuously rotatable two-conductor and single-conductor electrical connectors located in opposite sides of the frame and a coaxial cable and a single conductor wire disposed through opposed yoke-arm bushings, enabling energization of yellow, white, or both type LED's to thus illuminate a face or other object near the windows at three different selectable color temperatures.

  • Patent number: 8390247
    Abstract: A device for a plug in vehicle includes a cord with a ball-like covering that allows it to be dropped. The cord bounces when dropped, and no damage is caused. There is also an electrical actuator that is based on when the vehicle is in a mode that allows it to be charged. When the vehicle is in the charge mode, the actuator either magnetically attracts the cord, or tightens against the cord to hold it more tightly If the vehicle is put in reverse, for example, the actuator is deenergized, and the cord is less tightly held, facilitating its disconnection.

  • Patent number: 4845603
    Abstract: This mechanical joint allows relative rotation of two articles (one may be a stationary fixture), on an arbitrary axis. The joint has as much angular-rotation range as a hinge, but as many degrees of freedom as a ball-and-socket or universal joint. It allows transmission, between the objects, of force or flux (e.g., of electricity, gas, or liquid), or both. In can be used as an applied-force or motion sensor, varying electrical contacts or conductivity in response to relative motion or force applied between the articles. In one form the invention is simply a mechanical joint formed of two closely interlocked toroids. The minor cross-section of each toroid is sized to just fit through the central aperture of the other; there is a connection point on each toroid for attachment of one article. By adjusting closeness of fit, a designer can impart to the device a wide range of desirable frictional properties.
