摘要:
A power source, charging system, and inductive receiver for mobile devices. A pad or similar base unit comprises a primary, which creates a magnetic field by applying an alternating current to a winding, coil, or any type of current carrying wire. A receiver comprises a means for receiving the energy from the alternating magnetic field and transferring it to a mobile or other device. The receiver can also comprise electronic components or logic to set the voltage and current to the appropriate levels required by the mobile device, or to communicate information or data to and from the pad. The system may also incorporate efficiency measures that improve the efficiency of power transfer between the charger and receiver.

A system and method for distributed charging of mobile devices. In accordance with an embodiment, the system comprises a secondary coil or receiver associated with a mobile device. When the mobile device is placed in proximity to a base unit having one or more primary coils, each primary coil having a generally planar shape so that when a current is passed through the primary coil a magnetic field is generated in a direction substantially perpendicular to the plane of the primary coil, the perpendicular magnetic field is used to inductively generate a current in the secondary coil or receiver associated with the mobile device, to charge or power the mobile device. In accordance with various embodiments the system can incorporate efficiency measures that improve the efficiency of power transfer between the charger and receiver.
摘要:
A system for intelligent initiation of an inductive charging process. 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.
摘要:
An electronic device for inductive power transfer with a second electronic device is disclosed. The electronic device includes a first inductive coil and a permanent magnet strucrure for creating a magnetic attachment between the electronic device and the second electronic device. The permanent magnet structure is positioned around an outer perimeter of the inductive coil to align the inductive coil with a second inductive coil in the second electronic device for inductive power transfer. The permanent magnet structure forms a ring that includes a gap and includes one or more arc-shaped magnets. The permanent magnet structure is configured such that the electronic device can be rotated across a continuous range of angles with respect to the second electronic device while keeping alignment between the coils during inductive power transfer. The electronic device is configured to communicate with the second electronic device through a modulated current in the inductive coil.
