Abstract: A method and apparatus for wirelessly charging a chargeable device, such as a smart phone, digital music player, or navigation device, using a wireless charger. The wireless charger includes a connector, a retainer, and a wireless power transmitter. The connector is configured to secure the wireless charger to a visor in a passenger compartment of a vehicle. The retainer is configured to selectively retain a chargeable device having a recipient coil. The wireless power transmitter includes a charging coil configured to carry a fluctuating electric current that generates a changing magnetic field for receipt by a recipient coil of the chargeable device. The changing magnetic field induces a fluctuating electric current in the recipient coil, which is used to charge a battery pack of the chargeable device.

Abstract: A low-profile battery pack having an electrolyte barrier is provided. The pack includes a plurality of rechargeable cells, being arranged in end to end pairs of two cells. A cleavage void formed by the convex geometry of the cells accommodates at least one insulator and a first circuit board. Tabs couple the cells to the first circuit board. A flexible substrate couples the first circuit board to a second circuit board. The assembly is then placed in a housing having a first compartment and a second compartment, such that the cells are placed in the first compartment and the second circuit board is placed in the second compartment. Between the first and second compartments exists an electrolyte barrier. The flexible substrate passes through an opening in the electrolyte barrier. Adhesive placed in the opening, about the flexible substrate, ensures a seal that keeps electrolyte that may appear in the first chamber from passing to the second chamber.

Abstract: A latch assembly for coupling a rechargeable battery to an electronic device is provided. The latch assembly includes an insertable latch having barbed wing members extending distally from a planar member. The planar member includes several features, including an insertion snap, a spring retention post and a mechanical stop. The latch is inserted into a latch aperture in a battery pack housing. The latch aperture includes a plurality of slots for receiving the various features of the latch. A spring, like a butterfly spring for example, provides an outward force between the latch and the housing. The latch assembly is designed for ease of manufacture, in that assembly is simply inserting the spring in the latch aperture and then snapping in the latch.

Abstract: This invention includes an improved interconnect assembly for use in rechargeable battery packs for laptop computers. The invention eliminates manufacturing defects resulting from the hand soldering processes of the prior art. The assembly provides interconnection for rechargeable cells oriented end to end, in parallel rows. Insulated runners provide interconnection to a bus located along the center of the end to end cells. The bus is a flexible circuit that couples to a printed circuit board. In one preferred embodiment, the bus is less than two inches in diameter and less than the diameters of the parallel rows of end to end cells in length. The assembly eliminates the need for hand soldering, eliminates cumbersome wire routing, and offers multiple insulation features that prevent electrical shorts.

Abstract: Liquid foam control compositions provide good control for liquid detergent formulations, while being storage stable both before and after incorporation into liquid detergent.
