Abstract: The present disclosure describes a device installation system. The system includes a device having a wireless communication tag that stores device identification information and torque information for installing the device via a threaded fastener. The system further includes a tool for applying torque to the threaded fastener to install the device. The tool includes a wireless communication tag reader, a temperature sensor, and at least one processor in communication with the wireless communication tag reader and the temperature sensor. The processor is configured to obtain the device identification information and the torque information from the tag via the tag reader; obtain ambient temperature information in a vicinity of the device via the temperature sensor; and determine an amount of torque required to apply to the threaded fastener to install the device using the obtained device identification information, torque information, and ambient temperature information.

Abstract: An electrical connector includes a first connector element having a housing and a first power terminal providing electrical power to a heating element of a heating system, and a second connector element mateable with the first connector element. The second connector element has a second power terminal mateable with the first power terminal. The electrical connector includes an information storage unit storing a data usable for operating the heating system and a communication interface reading out the data stored in the information storage unit.

Abstract: A cartridge for an aerosol provision device comprises a chamber for containing a liquid from which a flow of aerosol for inhalation by a user is generated. The cartridge comprises a first connector arrangement for releasably connecting the cartridge to a body portion of the device, and a second connector arrangement for releasably connecting to a container for a material. In use, aerosol flows through the material in the container before being inhaled by the user. The first connector arrangement is configurable in a locked configuration and in an un-locked configuration, and the first connector arrangement must be configured in the un-locked configuration for the cartridge to be removeable from the body portion. The first connector arrangement is configurable from the locked configuration to the un-locked configuration while the cartridge remains stationary with respect to the body portion.

Abstract: The invention relates to a distribution module (1) and method for operating a distribution module. A distribution module comprises a housing (2) and a bus connection (3) and multiple device connections (4). Selection means (5), in particular a rotary selector switch, are provided, by means of which one of multiple communication protocols which are stored in a memory within the housing (2) can be manually selected from outside the housing (2). Alternatively, the selection means can also be configured as a DIP switch, membrane keyboard, touchscreen or key switch. The memory is preferably non-volatile. When a protocol is chosen and the controller parameterises the distribution module via said protocol, and a device then starts cyclic data exchange, the ID of said protocol is thereby also stored in a non-volatile manner. Electronic units such as computing units, memories, power supply and the suchlike are accommodated in the housing (2).

Abstract: An arc fault detector includes a shunt resistor deployed in a protected circuit, an arc discriminator sensing voltages across the shunt resistor and producing an arc indication deduced from current variations associated with parallel and series arc faults, a signal transformer buffering the arc detection signal and producing a pulse, a switch transient detector sensing a voltage differential across load switches and producing a pulsed switch transient signal when the voltage differential across load switches exceeds a reference value, a line interrupter, such as a static relay, a switch controller including logic gates generating a trip signal based on predetermined criteria, and a manual switch for resetting the line interrupter. An embodiment comprises a voltage sensing coil enveloping a toroidal core to detect current variations in conductors passing through the core.

Abstract: A contact structure for a sliding switch includes a conductive stationary contact disposed on a base and a conductive movable contact for electrically contacting the stationary contact. The movable contact is movable along a path between a non-contact position and a make-contact position with respect to the stationary contact, and at least one of the contacts has a protruding portion that provides an electrical interface for discharge of arcing as the movable contact breaks from the stationary contact. As a result, the invention prevents or substantially reduces degradation in switch performance which might otherwise be caused by debris accumulation associated with arcing.

Abstract: A fuse and relay box for a motor vehicle having an insulating housing, an electrical circuit, and a switching device. The housing having a cover that moves between an open position and a closed position. The electrical circuit is contained in the housing, connected to a motor vehicle electrical system connection and has electrical components. The switching device has a contact bridge that connects the vehicle electrical system connection to the electrical circuit when the cover is moved to a closed position and disconnects the vehicle electrical system connection to the electrical circuit when the cover is moved to an open position. The switching device is coupled to a sensor element for detecting whether the cover is in the open or closed position.
