Problems solved by technology

However, such a device may be tethered to a person's battery pack via a cable
For devices such as headlamps, microphones, night vision goggles, etc. that are carried on the person's head or helmet, the cables can be uncomfortable, restrict movement, and pose a safety risk (because the cables can get in the way or get caught in objects and obstacles) and reduce system reliability

Embodiment Construction

[0065] Wireless battery construction

[0066] Resonators and electronics can be integrated into or placed close to the battery to enable wireless energy transfer to the battery, allowing wireless charging of the battery pack. With the addition of a resonator and control circuitry, cells and packs can wirelessly draw energy from a source and recharge without having to be precisely positioned within a charger. Wireless batteries and battery packs can be wirelessly recharged inside the host device from an external wireless power source without requiring the device to be physically plugged into an external energy supply.

[0067] Figure 6 One example of a wireless battery including a magnetic resonator is shown. The exemplary battery includes a resonator coil 606 wound around an optional block 608 of magnetic material. The block of magnetic material 608 may be hollow and may house power and control circuitry (not shown) and optionally a rechargeable battery 604 that may be rec...

Abstract

A wireless energy transfer enabled battery includes a resonator positioned asymmetrically within a battery sized enclosure such that when two wireless enabled batteries are positioned in close proximity, the resonators of the two batteries have low coupling.
