Lot Summary
This patent portfolio discloses an optical battery charger for charging batteries of an electrical or electronic appliance. Conventionally, as the physical dimensions of other battery charging devices shrink, or operation in harsh or wet environments is desired, physical contacts of the charging terminals become increasingly difficult to implement. Similarly, as power requirements increase or the area available for a photovoltaic receptor diminishes, solar charging becomes limited. Additionally, inductive coupling used in conventional devices also limit the target appliance housing to nonconductive materials. Thus, new battery charging devices that can recharge batteries contained in a sealed housing in a target appliance or device are desired.
Value Proposition: This portfolio addresses market limitations by disclosing a device for recharging batteries of electronic appliances where exposed contacts are undesirable. The target appliance can be any portable electronic device with modest power requirements. The battery charger includes a portion integral to the target appliance consisting of one or more photovoltaic receptors and a charging unit. The external portion consists of an electrical power source, a focused solid-state light source such as an infrared LED or laser diode, and a physical cradle that aligns the target appliance’s receptor to the light source. Further, the photovoltaic receptors can be placed anywhere on the target appliance’s surface, or behind a transparent portion of its housing. This technology is a major improvement over old and current systems: in original systems an electrical plug was required for both synching and recharging; some current systems (i.e. cloud enabled) allow for no-plug synching but still require a power plug for battery charging. Using the technology disclosed in this patent portfolio along with a cloud based service for synching, a device could be completely sealed improving its durability and extending its anticipated useful life.
