Abstract: A lighting apparatus includes a first electrical contact (5212) that receives power and a second electrical contact (5304) that provides access to the received external power. An electrical contact support component (5210) is used to configure the orientation of the first electrical contact (5212) with respect to the second electrical contact (5304) and connect the first electrical contact and the second electrical contact. A portable lighting appliance receiving region (5310) receives and provides power to a received portable lighting appliance (5206). An interface (5226) receives an input indicative of a first operation of the received portable lighting device (5206) when the power is available and a second operation of a received portable lighting device (5206) when the power is unavailable.

Abstract: The invention pertains to housings and enclosures for assemblies of electrochemical cells such as used in consumer electronic devices. A system of structural elements having constant cross-section along at least one axis is provided to construct protective housings for electrochemical cell assemblies. Where cell assemblies include sensitive circuit elements such as circuit boards the fabricated housings include cover portions to reduce the chance of impact or contact damage to the circuit elements. By designing structural elements having open and constant cross-sections, a family of housing components may be fabricated from a single structural element by altering a length. Different configuration housings may also be constructed by rearranging the housing components or introducing additional interconnecting components. By incorporating a unified interconnecting element into each component, interchangeability is increased.
