Abstract: A method for human movement classification includes a plurality of radio frequency (RF) antennas to expose a body surface of a human user to an E-field, at least a part of the human user positioned within a near-field region relative to the RF antennas. The plurality of RF antennas are scanned to determine ground-relative changes in electrical conditions. A differential-scanning subset of RF antennas are selected, including two or more RF antennas for which the changes in electrical conditions exceed a threshold. For each RF antenna in the differential-scanning subset, a set of antenna-relative changes in electrical conditions are determined by comparing the RF antenna to one or more other RF antennas in the differential-scanning subset as a plurality of pairs. Based at least in part on the ground-relative changes in electrical conditions and the antenna-relative changes in electrical conditions, a movement performed by the human user is classified.

Abstract: 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.

Abstract: A computer implemented method includes accessing a first status of a first battery pack interface coupled to a load via a first load switch and accessing a second status of a second battery pack interface coupled to the load via a second load switch. The first status and the second status are compared and the first and second load switches are controlled based on the comparing to balance remaining capacities of the first and second battery packs.
