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.
