Abstract: An anode active material for lithium ion batteries includes one or more unaggregated silicon particles having a mass-based chlorine content of from 5 to 200 ppm and a volume-weighted particle size distribution having diameter percentiles d50 of from 0.5 ?m to 10.0 ?m.

Abstract: The present invention is a wireless communication device which includes a circuit board with a coating, a top housing, a bottom housing and a gasket. The wireless communication device is preferably a water-tight enclosure. A method for forming a water-proof wireless communication device is also disclosed.

Abstract: A system for wireless communication comprises a first communication device having a first interface for interfacing with a host device and a second interface; and a second communication device configured to be coupled to the second interface of the first communication device. The first communication device and the second communication device, when coupled, form a substantially integrated device.

Abstract: An electronic component cover comprises a plate having a first region adapted to substantially cover at least one side of a first electronic component. The plate is adapted to accommodate a second electronic component thereon, such as a SIM card or a SIM card reader. The plate may include a second region to accommodate the second electronic component therein. The electronic component cover may comprise one or more leads adapted to provide electrical communication between the first electronic component and the second electronic component. The one or more leads are electrically isolated from the plate. The cover may further comprise a nonconductive mount adapted to accommodate the second electronic component thereon. The nonconductive mount secures the one or more leads to the plate while electrically isolating the one or more leads from the plate.

Abstract: An electronic device includes a first printed circuit board including electronic components, a second printed circuit board including electronic components, and a shielding midframe. The shielding midframe is adapted to provide electromagnetic isolation between the first printed circuit board and the second printed circuit board. The shielding midframe is further adapted to provide electromagnetic isolation of electronic components on at least one of the first printed circuit or the second printed circuit.

Abstract: A battery charger includes a main housing (103). A well (108) in the main housing is for receipt of an electronic device (102) including a battery. A door housing (104) is movably carried on the main housing. At least one contact (422) is carried on the main housing for connection to a battery (200, 300) inserted between the door housing and the main housing, wherein the door housing is movable between an open position for receipt of a battery and a compact closed position. A circuit is positioned in the main housing for electrical connection to the electronic device and the contacts for charging a battery.
