Abstract: A magnetic component, like an amorphous metal ribbon component, is disposed within an aperture of a layer of circuit board substrate, like FR4 or a flexible substrate. That layer is then laminated between a top and bottom layer to form a circuit substrate with a magnetic component integrally formed therein. Conductive traces are disposed on the top layer and bottom layer. These conductive traces are coupled together about the magnetic component with conductive vias. The top traces, bottom traces and conductive vias form a “winding” about the magnetic component. The resultant assembly is a single, multi-layered circuit substrate with a magnetic circuit element integrally formed therein. The magnetic circuit component is suitable for use as, amongst other things, an inductor, a transformer, or a contactless charging primary or secondary coil.

Abstract: The invention concerns a method (300) and system (100) for selectively charging a battery (112). In one arrangement, the method can include the steps of coupling (311) the battery to a first power supply (114), coupling (311) the battery to a second power supply (116), determining (312) an available charging current parameter for the battery and selectively enabling (314) a charging circuit (120) for the first power supply and a charging circuit (122) for the second power supply based on the available charging current parameter of the battery. The selectively enabling process can be based on maximizing (316) an available charging current of the battery and minimizing (320) a power dissipation of the battery. As an example, the first power supply can be a hard-wired charger (114), and the second power supply can be a wireless charger (116).

Abstract: An adaptor for converting a conventional electronic device into one capable of being charged by a contactless charger is provided. The adaptor has a base member that couples to the electronic device, and a sliding member that includes a contact block for electrically coupling the adaptor to the electronic device. The base member includes a contactless pick-up coil for receiving energy from a conatactless charger. The base member is coupled to the electronic device, and the sliding member is moved from an extended position to a retracted position, thereby coupling the electrical contacts of the contact block to a charging receptacle on the electronic device.

Abstract: This method of charging includes a method of terminating charge when three events have occurred: a voltage across at least one of the cells reaches a predetermined maximum voltage, the average charging current falls below a predetermined minimum current, and the presence of a power source has been detected. The method also includes a safety termination that prohibits charge upon the expiration of a timer when the cells have stored little or no energy.
