Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A circuit for balancing battery cells includes a plurality of resistors configured in parallel with the battery cells, and a plurality of switches configured in series with the resistors. A control circuit causes the switches to balance the battery cells based on detected voltage of the battery cells and based on past operation of the cells.

Abstract: A battery system monitors the status of a battery and ensures safe conditions under a range of events adversely affecting the safety of the battery cells, the battery pack or enclosure, or a vehicle housing the battery. In response to the safety event, the battery system provides one or more responses to secure the battery, disconnect the battery, extinguish a fire, or maintain a safe temperature. Upon detecting the safety event, the a controller activates the safety device accordingly to ensure safe conditions.

Abstract: 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.
