    摘要: A multi-mode air compressor pressure switch is disclosed. A first mode of operation of the switch has a first range that includes a first cut-out pressure and a first cut-in pressure. A second mode of operation of the switch has a second range that includes a second cut-out pressure and a second cut-in pressure. The second range is smaller than the first range. The second mode of operation adds compressor output over the first mode of operation to extend operable time of a tool that is connected to a compressor that is controlled by the first mode and the second mode.

    摘要: A system and method for charging battery packs is provided. The system may include a charging pad comprising a power supply, a charging pad surface, and a microcontroller unit. The power supply may provide charging power. The charging pad surface may include a first charging region and a second charging region. The microcontroller unit may control delivery of charging power to the first charging region and the second charging region such that a device placed in contact with the first charging region is given a higher charging priority than a device placed in contact with the second charging region.

    摘要: A rechargeable device is disclosed. The rechargeable device may include an enclosure, a rechargeable battery cell, a constellation assembly, and charging circuitry. The enclosure may include a receptacle defining a longitudinal opening into the enclosure. The constellation assembly may include a diaphragm, a puck, and a contact point affixed to the puck and configured to engage an electrode of a charging pad surface. The charging circuitry may be configured to charge the battery cell based on electrical power received from the charging pad surface via the contact point. The receptacle may further permit movement of the puck and the affixed contact point along the longitudinal opening.
