A control system (300) allows recognized standard premise electrical outlets, for example NEMA, CEE and BS, among others to be remotely monitored and/or controlled, for example, to intelligently execute blackouts or brownouts or to otherwise remotely control electrical devices. The system (300) includes a number of smart receptacles (302) that communicate with a local controller (304), e.g., via power lines using the TCP/IP protocol. The local controller (304), in turn, communicates with a remote controller (308) via the internet.

A field-connectable cable cap for a heating cable in which the cable cap includes a power indicator that illuminates when sufficient power is supplied to the distal end of the heating cable. The indicator gives an installer or a user an indication that the heating cable is functioning properly the entire length of the heating cable. The cable cap may further include a connection feature, such as an aperture, that provides a connection point for a cable pulling device such as a fish tape.

An electrical power unit is positionable in or along a work surface and includes a housing with a movable cover that is positionable in open and closed positions at an upper region of the housing. The cover defines an interior region in which a wireless power transmitter is mounted. A lamp unit is disposed in the housing or the cover. The lamp unit is configured so that emitted light is visible from outside the power unit when the cover is closed. The wireless power transmitter is operable to selectively illuminate the lamp unit when the wireless power transmitter is energized. Optionally, at least one direct-contact electrical or data receptacle is provided at the housing, and may be arranged or positioned so that it is accessible at least when the cover is in the open position.

Modular switchboard terminal block (10,20) for transmission of data signals (2) is provided, comprising a container (10a,20a) having, arranged inside it, a printed circuit (30) for processing the data signals, which has two opposite sides (30a,30b) in a transverse direction (Y-Y); connectors (11;21) for electrical connection to controlled/detection devices; and a rear end face provided with hook and spring means for mounting on a DIN switchboard rail (6).

A cable for communicating digital or analog signals between connectors at its opposite ends has means for indicating to an installer who has access to one end of the cable which connector is connected at the opposite end of the same cable. The cable also has means for illuminating a receptacle to which an installer is connecting the cable connector. A light source is mounted in each connector that can be turned on from a switch in the connector at the opposite end. The light source is configured to radiate light both transversely from its connector for an indicator function and also longitudinally from its connector for an illumination function. Multiple light sources can be used at each connector for those two functions. The illumination function can be activated from a switch at the same end as the light source. Implementation with logic circuits, microcontrollers and/or other semiconductor devices allows for a variety of embodiments.

A technique for setting network communications for a computer host having multiple network interface controllers (NICs) includes performing network communication for a baseboard management controller (BMC) using a first NIC. In response to actuation of a switch of a network connector jack that is associated with the first NIC, a switching signal is sent from the switch to the BMC. In response to receipt of the switching signal at the BMC, network communication for the BMC is performed using a second NIC.

A cable connector assembly (100) includes a mating member (10) adapted to be mated with a mating connector, a cable (20) electrically connected with the mating member, a strain relief member (30) enclosing the cable, and an outer shell (40) assembled at outer sides of the mating member and the strain relief member. The outer shell includes a first shell (41) and a second shell (42) mated with the first shell. The strain relief member includes a mating portion (31) enclosed by the outer shell and a ring portion (32) connected with the mating portion. Both of the first shell and the second shell are latched with the mating portion.

An electronic cable system operates as an extension cable to facilitate external viewing of internal infrastructure LED status. A wired cable is provided having a first end and a second end, the first end including a first I/O coupler, LED detectors and a power jack; and the second end including a second I/O coupler and a plurality of LEDs. The plurality of LEDs of the second end illuminate in response to activation of the LED detector of the first end. The first I/O coupler may plug into an internal module of electronic infrastructure, such as a server, to detect operational status of the internal module via the LED detectors. The second I/O coupler may couple to infrastructure housing, permitting the plurality of LEDs to be viewed externally of the housing. The plurality of external LEDs on the infrastructure housing mimic internal (non-viewable) status indicator LEDs of the internal module.

To intuitively identify the state o an electronic device.

There is provided an electronic device that implements a predetermined function, the electronic device including: an operation detection unit configured to detect a physical operation on the electronic device; a transmitter configured to transmit operation information indicating the operation to an external device; a receiver configured to receive feedback information indicating at least a type of feedback representing a state relating to the function, the feedback information being transmitted by the external device in response to the operation information; and a feedback unit configured to provide the feedback in accordance with the feedback information.

A socket detection apparatus for supporting anomaly detection of an earth wire and a neutral wire includes: a micro-control unit, provided with a test plug of a fire wire connection end, a neutral wire connection end and an earth wire connection end, and a detection circuit connected with the test plug; and an induction antenna arranged corresponding to a fire wire end of a detected power socket, the induction antenna being connected with a first signal input end of the micro-control unit.
