    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 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.

    摘要: Various embodiments of tools with integrated measurement devices are described. An apparatus may include a tool to be applied to a workpiece, an integrated measurement device in a feed path of the tool, and a controller. The integrated measurement device may generate signals indicative of rotation of a roller in a feed path of a workpiece. The controller may generate, based on the signal, a distance measurement of the workpiece. The distance measurement may indicate a distance between an end of the workpiece and a location of the workpiece to which the tool is to be applied.

    摘要: A redundant actuation lock apparatus includes an interface, an electronic mechanism, and a manual mechanism. The interface manipulates lock bar(s) into a locked/unlocked position. The electronic mechanism includes an actuator and power drive. The actuator is disengageably coupled to and drives the interface. The power drive is coupled to and drives the actuator in response to a control signal. The manual mechanism includes a key input and an output. The key input receives and rotates with a mechanical key. The output disengageably couples to the interface and rotates with the mechanical key. The actuator is engaged with and the output is disengaged from the interface in an electronic mode, while the actuator is disengaged from and the output is engaged with the interface in a manual mode.
