The present disclosure provides a display device, a display apparatus, and a method for manufacturing a display device. The display device comprises a mainboard, a display panel disposed on the mainboard, and a fingerprint recognition sensor. The fingerprint recognition sensor is disposed on the mainboard, and the fingerprint recognition sensor is located between the mainboard and the display panel. A groove is formed on a surface of the display panel facing the mainboard, and an orthographic projection of the groove on the mainboard corresponds to a position of the fingerprint recognition sensor. The groove is configured to form an air gap between the fingerprint recognition sensor and the display panel.

A system for controlling operation of a power tool. The system includes a handpiece having a power tool, a radio frequency identification (RFID) tag, and a wireless transceiver. The system also includes a power pack having an electric motor driving the power tool. The power pack also includes a wireless transceiver, an RFID reader, and non-transitory computer-readable storage media having computer-executable instructions for pairing the handpiece to the power pack. When executed by at least one processor, the computer-executable instructions cause the at least one processor to: interrogate the RFID tag with the RFID reader; receive an RFID signal from the RFID tag including identifying information for the handpiece; store the unique identifying information for the handpiece at the power pack; and, based on receipt of the unique identifying information, complete wireless pairing of the handpiece to the power pack.

An electronic transaction card communicates with an add-on slot of an intelligent electronic device. The add-on slot may be a memory card slot. The intelligent electronic device may be a mobile phone or other device with or without network connectivity. The electronic transaction card may have magnetic field producing circuitry compatible with magnetic card readers, smartcard circuitry, other point-of-sale interfaces, or any combination thereof.

An industrial system includes an electronic badge worn or otherwise transported by an industrial vehicle operator. The electronic badge has a housing, a processor, and a transceiver coupled to the processor that communicates on a personal-area network with a badge communicator that is provided on an industrial vehicle when the electronic badge and the badge communicator are in range of each other. Further, an activity sensor collects activity information about the industrial vehicle operator as the industrial vehicle operator performs work tasks. The electronic badge exchanges data collected by the activity sensor with the industrial vehicle, for communication to a remote server. An electronic message is communicated to the industrial vehicle for output to a display thereon, and the electronic message defines an assigned task that is based upon previously collected data from the activity sensor.

A power pack for a power tool. The power pack includes an electric motor configured to drive a power tool. The power pack also includes a motor controller with a relay circuit communicating with the electric motor. The relay circuit has a switch that may be connected to a power supply, whereby the power supply powers the electric motor. The power pack also comprises non-transitory computer-readable storage media having computer-executable instructions for monitoring operation of the power pack. When executed by at least one processor, the computer-executable instructions cause the at least one processor to: monitor input data relating to operation of the power pack; determine, based at least in part on the input data, that operation of the power pack deviated from an ideal state; and, based on the determination of deviation, cause the switch to electrically disconnect the electric motor from the power supply.
