A power pack for a power tool. The power pack includes an electric motor configured for driving engagement with the power tool. The power pack also includes a motor controller having a relay circuit connected a electric motor. The relay circuit includes has a switch selectively connected to a power supply. The power supply powers the electric motor. The motor controller also includes non-transitory computer-readable storage media having computer-executable instructions for monitoring operation of the stored 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 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.

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 interactive core for use in making electronic cards has rear and front adhesive layers which surround a stiffening spacer which has an interior opening in which electronic components (e.g., a PCB, battery and display) are located along with thermosetting polymeric material. A battery contained within the interior opening can be activated from an off state to an on state via use of an initialization antenna which can also be configured to allow a CPU to be customized for personal use.

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.

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.

An electronic badge comprises a housing having a form factor of a mobile device, a processor, and memory coupled to the processor and including an observation and feedback application. Further, the electronic badge comprises a first transceiver that communicates on a first personal-area network, a second transceiver that communicates on a second personal-area network, and a third transceiver that communicates on a local area network. An information feedback device is controlled by the processor to activate to provide information to the user that feedback has been either given or received, wherein the information feedback device is operated by the processor in response to the processor executing the observation and feedback application, and in response to the processor interacting with at least one of the first transceiver, the second transceiver, and the third transceiver.
