  • Publication number: 20220391196
    Abstract: A light assembly system includes a light assembly and a software reflash kit for updating software of an internal control unit of the light assembly. The light assembly is constructed for releasable receipt of an electrical communication device of the software reflash kit. The light assembly includes a housing, the control unit, and an access port. The housing defines an enclosed, sealable, chamber. The control unit is located in the chamber. The access port is defined by and communicates through, the housing, and is adapted to receive the electrical communication device for detachable electrical engagement to the control unit.

  • Patent number: 5374843
    Abstract: A high voltage integrated circuit (IC) has a passivation structure that shields the underlying circuit from the electrical effects of charge on the passivation structure. In one embodiment, the passivation structure comprises a silicon rich nitride layer in electrical contact with underlying circuit elements. The silicon rich nitride is highly resistive and permits only a negligible current between elements, but is conductive enough that charge on the surface of the passivation structure flows into the IC before the electric fields in the underlying circuit elements is significantly changed. In another embodiment, the passivation structure has two or more layers with a less conductive layer in contact with the underlying IC and overlying conductive layer which shields the IC from the effects of charge build up.
