The invention relates to an assembly comprising a main device and an accessory, which can be connected by a safe connector and a safe detection method. According to the invention, the assembly comprises: a main device (2), an accessory (3) connectable to the main device (2), the accessory (3) comprising an accessory connector (4) for mating with a device connector (5) of the main device (2), the accessory connector (4) and the device connector (5) each comprising one or more supply contacts (7) for transmitting electric power from the main device (2) to the accessory (3), the main device (2) comprising a detection device (9), which, if connecting the accessory (3) to the main device (2), receives complex accessory data stored by the accessory (3) and which by positive evaluation of the complex data enables applying a supply voltage at the one or more supply contacts (7) of the device connector (5).

A modular extendable outlet assembly comprises multiple selectively removably couplable outlet units. The units comprise an electrical housing with a first end, a second end opposing the first end, a visible front face having a first electrical socket, a rear face having a mount wall with holes, and a sidewall enclosing a unit cavity. An electrical plug retractably extends from the second end of housing. The electrical plug has an electrical prong configuration corresponding to a prong configuration of the second electrical socket to mate with an adjacent outlet unit. A spool assembly disposed within the unit cavity operates with a spring-loaded spool member. An electrical cord wraps around the spring-loaded spool member, terminating at the electrical plug. A cord release switch selectively translates the spring-loaded spool member to rotate and extend in length, the electrical cord. A unit activation switch electrically couples to the first electrical socket for powering.

An electronic circuit includes an output generator and an over-voltage detector. The output generator is configured to output an output signal to an output terminal. In response to an amplitude of a voltage of the output terminal being greater than an allowable amplitude, the over-voltage detector is configured to output an over-voltage detection signal of a first logic value, such that elements included in the output generator are turned off. In response to the over-voltage detector outputting the over-voltage detection signal of the first logic value again before a reference time elapses after the first logic value of the over-voltage detection signal changes to a second logic value of the over-voltage detection signal, the turned-off elements remain turned off. In response to the over-voltage detector outputting the over-voltage detection signal of the second logic value during the reference time, the turned-off elements are turned on.

Remote management of network interface peripheral cards uses physical pin reassignment and a dedicated management network. One or more physical pins in a connector may be dynamically redefined from an interface protocol to a different interface protocol. The dynamic redefinition allows existing input/output signals to be routed to the pins to provide remote management features.

A communication connector has a housing for receiving a communication plug, a printed circuit within the housing, a switch which actuates the printed circuit board, and a translating crossbar which engages the switch. The printed circuit board is moved dependent upon a type of plug inserted. The movement of the circuit board can help to selectively engage one of two sets of circuit traces and groupings of contacts.

Embodiments herein are directed to an error proofing system that determines whether an assembled squib device is properly assembled is provided. The assembled squib device has a connector seated within a canister. The error proofing system includes an electronic control unit and an electrical device. The electrical device includes a body and a head portion. The body includes a wireless transmitter. The head portion includes three micro-switches electrically coupled to the wireless transmitter and is shaped and sized to receive a portion of the connector of the assembled squib device to make contact between the connector and at least one of the three micro-switches and to make contact with an uppermost surface of the canister such that a different two micro-switches of the three micro-switches make contact with the uppermost surface when the connector is properly installed within the canister to form the assembled squib device.

An electronic device has a first terminal for receiving power from a connected external device, a second terminal for obtaining information of the external device, and a GND terminal connected to the second terminal. The electronic device causes a resistance between the second terminal and the GND terminal to change, and determines a type of the external device based on a voltage of the first terminal after the resistance is caused to change.

An interface includes a connector that is physically and electrically connectable to a device conforming to a first interface standard and a device conforming to a second interface standard, and an interface circuit including a signal line extending to a terminal of the connector, a coupling capacitor disposed on the signal line, and a switch having a first end electrically connected to a first terminal of the coupling capacitor and a second end electrically connected to a second terminal of the coupling capacitor. The switch is turned on when the connector is connected to a device conforming to the first interface standard so that a signal bypasses the coupling capacitor and is transmitted through the switch and turned off when the connector is connected to a device conforming to the second interface standard so that the signal is transmitted through the coupling capacitor.

Disclosed is an interface device capable of simultaneously connecting an audio device and charger to an electronic device. An interface device may enable an electronic device with a single USB type-C connector but no analog audio jack to connect to both an audio device and a charger through the USB type-C connector. The interface device may provide automated quick charging when connected with the charger but not with the audio device.
