Techniques herein provide wireless energy transfer to audio devices such as headphones, headsets, hearing aids, and the like. Audio devices are integrated with a device resonator. The device resonator may be positioned and oriented to reduce interaction with lossy or sensitive components of the audio device. A repeater resonator and/or a source resonator is integrated into a headrest of a seat or a chair providing continuous power to the headphones while in use. The audio devices may be recharged wirelessly when positioned near source resonators that may be embedded in pads, tables, carrying cases, cups, and the like.

Wirelessly powered audio devices

Described herein are improved capabilities for a system and method for wireless energy distribution to a mechanically removable vehicle seat, comprising a source resonator coupled to an energy source of a vehicle, the source resonator positioned proximate to the mechanically removable vehicle seat, the source resonator generating an oscillating magnetic field with a resonant frequency and comprising a high-conductivity material adapted and located between the source resonator and a vehicle surface to direct the oscillating magnetic field away from the vehicle surface, and a receiving resonator integrated into the mechanically removable vehicle seat, the receiving resonator having a resonant frequency similar to that of the source resonator, and receiving wireless energy from the source resonator, and providing power to electrical components integrated with the mechanically removable vehicle seat.

System for wireless energy distribution in a vehicle

Wireless energy transfer devices and systems for medical environments include, in at least some implementations, a wirelessly powered surgical device including: a device resonator configured to generate an oscillating voltage from a captured oscillating magnetic field; and a surgical tool electrically coupled to the device resonator, the surgical tool having a functional output that is capable of being directly powered by the oscillating voltage, and the surgical tool having a rechargeable battery backup; wherein the oscillating voltage is at least 30 volts and has a frequency of at least 1 kHz. Wireless energy transfer is utilized to eliminate cords and power cables from operating instruments and electronic equipment, facilitating mobility.

Wireless energy transfer for medical applications

Described herein are systems for wireless energy transfer distribution over a defined area. Energy may be distributed over the area via a plurality of repeater, source, and device resonators. The resonators within the area may be tunable and the distribution of energy or magnetic fields within the area may be configured depending on device position and power needs.

Wireless energy distribution system

Described herein are improved configurations for a wireless power transfer. Described are methods and designs for medical environments and devices. Wireless energy transfer is utilized to eliminate cords and power cables from operating instruments and electronic equipment requiring mobility.

Described herein are improved configurations for a resonator enclosure for wireless high power transfer that includes a support plate, a sheet of good conductor positioned on one side of the support plate, a separator piece for maintaining a separation distance between the resonator and the sheet of good conductor, and a cover of a non-lossy material covering the resonator, the separator, the sheet of good conductor and attached to the support plate, wherein the size of the sheet of good conductor is larger than the size of the resonator.

Wireless energy transfer resonator enclosures

Described herein are improved configurations for a lighting system with wireless power transfer that includes a source high-Q magnetic resonator coupled to a power source and generating an oscillating magnetic field, at least one device high-Q magnetic resonator configured to convert said oscillating magnetic field to electrical energy used to power a light coupled to the at least one device resonator, and at least one repeater resonator, larger than the device resonator, wherein the repeater resonator is positioned further from the source resonator than the device resonator and improves the power transfer efficiency between the source resonator and the device resonator.
