Abstract
A system for intelligent initiation of an inductive charging process is provided. In accordance with an embodiment, the system comprises a receiver coil or receiver associated with a mobile device, and provided as a separable or after-market accessory for use with the mobile device. When the mobile device is placed in proximity to a base unit having one or more charger coils, the charger coil is used to inductively generate a current in the receiver coil or receiver associated with the mobile device, to charge or power the mobile device. The base unit and mobile device communicate with each other prior to and/or during charging or powering to determine a protocol to be used to charge or power the mobile device.
Claims15
A system for providing universal or improved compatibility and transfer of wireless power to mobile devices and batteries, comprising:
- a charger including a charger coil and one or more half-bridge drivers and/or microcontroller units or other current and/or voltage controlling components, wherein the charger includes a circuit or other components that measures the current through and/or voltage across the charger coil, and wherein the microcontroller unit receives a communication signal from a detection/demodulation circuit and makes appropriate adjustments to the charger coil drive circuitry to achieve the desired output voltage, current or power from the receiver output, for using in powering or charging a mobile device and/or battery.
A method for providing universal or improved compatibility and transfer of wireless power to mobile devices and batteries, comprising the steps of:
- providing a charger including a charger coil and one or more half-bridge drivers and/or microcontroller units or other current and/or voltage controlling components, wherein the charger includes a circuit or other components that measures the current through and/or voltage across the charger coil, and wherein the microcontroller unit receives a communication signal from a detection/demodulation circuit and makes appropriate adjustments to the charger coil drive circuitry to achieve the desired output voltage, current or power from the receiver output, for using in powering or charging a mobile device and/or battery.
A system for attachment or fastening of one or more device, component, or part thereof to another device, component, or part thereof, using a multi-pole magnet comprising:
- a first magnet attached to or included within a first one of the device, component, or part thereof, wherein the first magnet includes more than one magnetic pole;
- and
- a second magnet or a magnetic or ferromagnetic material attached to or included within or on second of the device, component, or part thereof, which is magnetically attracted to the first magnet to provide a measure of alignment, attachment or fastening of the first and second devices, components, or parts.
A method for the use of magnets in electronic devices and/or battery, and in particular to devices or parts having proximity to magnetic sensors, comprising the steps of:
- providing a first magnet attached to or included within a first one of the device, component, or part thereof, wherein the first magnet includes more than one magnetic pole, and a second magnet or a magnetic or ferromagnetic material attached to or included within or on second of the device, component, or part thereof, which is magnetically attracted to the first magnet to provide a measure of alignment, attachment or fastening of the first and second devices, components, or parts.
