Abstract: A power tool including a sensor attachment, a housing, a motor, and a power tool controller. The power tool controller is operable or configured to control power provided to the motor. The sensor attachment is coupled to the power tool's housing and includes a first non-contact sensor and a sensor controller. The sensor controller receives signals from the first non-contact sensor related to distance to a work surface and determines a fastener depth based on the signals from the first non-contact sensor. If the fastener depth is greater than or equal to a desired fastener depth, the sensor controller generates and sends a control signal to the power tool controller. In response, the power tool controller turns off or cuts power to the motor.

Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of pigmented ink. Its housing defines an interior and exterior. The interior retains the ink and an exit port supplies it to an imaging device. Users orient the housing to deplete the ink in a direction of gravity toward a bottom surface of the interior en route to the exit port. The ink passes through a mixing chamber having inlet ports arranged to restrict to multiple different heights the entrance of the volume of ink from the interior. As ink draws from various heights into the chamber, sediments in the pigment mix together. The design overcomes settling. It also avoids mechanical stirring and other complex mixing techniques. Further embodiments include chamber shapes, configuration of inlet ports, and construction of the supply item, to name a few.

Abstract: An electronic system (30) includes several computers (32, 34, 36, 40) in data communication with one another. An electronic window sticker computer (EWS) (32) resides at each vehicle (28) on a dealership lot (22). The EWS computers (32) communicate with the remainder of the system (30) through an RF network (54). A book-in process (78) and/or a lot manager process (146) form a VIN record 96 for a vehicle (28) to which an EWS (32) has been assigned. The VIN record (96) includes a robust set of promotion presentation data (74) that are presented at the EWS (32) using a plurality of screens (112). User inputs are collected at the EWS (32) and routed to the lot manager process (146). Updates to the promotion presentation data (74) may be made frequently, and some updates may be made automatically (204). The updates are reflected at the EWS (32) in real time.
