Headphone playback devices can include a cable assembly including a plurality of conductors extending between a first earpiece and a second earpiece. The cable assembly includes a jacket, a power conductor disposed within the jacket and coupled between a power source in the first earpiece and a wireless transceiver in the second earpiece. The cable assembly further includes a microphone conductor at least partially disposed within the jacket and coupled to a microphone in one of the earpieces. A shield is at least partially disposed between the power conductor and the microphone conductor to reduce electromagnetic interference between the two.

Cable assemblies for headphone devices

Embodiments for a base and an assembly of a device and the base are provided. The assembly includes a device having at least one device alignment magnet along a surface of the device, and a base having, along an upper surface of the base, at least one base alignment magnet configured to act on the at least one device alignment magnet to align the device on top of the base, and at least one insert orthogonally plungable through the upper surface of the base. In a first position, the insert is below the upper surface of the base. In a second position, the insert protrudes the upper surface of the base and is contact with the device.

Device base

Adjacent battery cells connected in devices are balanced by closing a first circuit to charge an energy storage device from a first battery cell and thereafter simultaneously opening the first isolated switch and closing a second isolated switch to cause the energy storage device to charge a second battery cell. A circuit includes an isolated switch that operates simultaneously to balance battery cells connected in series, and a battery system balances battery modules connected in series, the battery module including battery cells connected in series. The battery cells and modules can be balanced by hierarchical balancing of modules of the battery pack and component cells of the modules.

Method for balancing cells in batteries

The present invention provides a principally novel method and a device for percutaneous electrical nerve stimulation and electro-acupuncture. It consists of inserting the needles/electrodes into the prescribed acupuncture/trigger points at slant angles so that the external parts of the needles/electrodes can be secured against the skin of the patient. Although the present method allows for usage of different types of percutaneous electrodes and perpendicular insertions, as long as the external parts of electrodes are in flush with the patient's skin, angular insertion of the needles/electrodes has significant advantages. First, the inclined position of the needle provides distribution of current over a larger area of the patient's skin since the inserted part of the needle is longer in the inclined position that in the perpendicular position. Second, as the projecting part of the needle is secured to the surface of the skin, a patient is not restrained by the needles and may have freedom of motion. In other words, after insertion of the needles the patient may leave the clinic and may not be bound to the clinic during subsequent usage of the device.
