摘要: The uneven charge and discharge from non-collocated batteries within an HMD can be solved by monitoring the DC current on the paths coupled to the first battery and the second battery and making an adjustment in the path resistance to equalize, or at least reduce, the difference between the currents on the two paths. Aspects of the technology described herein monitor current on paths from two or more non-collocated batteries. When the currents are different, resistance is dynamically added to the path with the higher current to equalize the current in the two paths. The monitoring and resistance adjustment can occur during discharge from a battery to a load and during battery recharge.

摘要: An electronic assembly that includes a rigid printed circuit board having an upper surface with a first plurality of lands. The electronic assembly further includes a flexible printed circuit board having a second plurality of lands on an upper surface. The lower surface of the flexible printed circuit board is directly attached to the upper surface of the rigid printed circuit board. The electronic assembly further includes a plurality of wires. Each of the wires is bonded to the first plurality of lands on the upper surface of the rigid printed circuit board and the second plurality of lands on the upper surface of the flexible printed circuit board.

摘要: Technologies are described herein for a two-wire power delivery system that may be employed by a mobile device with a reversable cable. The described techniques allow for the two-wire power cable to be inserted in any orientation into the mobile device, without requiring a special keying or registration element, and without requiring any additional pins or wires. The mobile device includes a passive protection circuit that assists the two-wire power cable system in detecting the correct orientation for power delivery.
