| 361191000 | Plural relay or solenoid load selectively operated | 6 |
| 20090067110 | Switching Device and a System Comprising the Same - A switching device comprising switching means for switching at least one current phase between responsive current phase input and responsive current phase output, the switching device being suitable for switching electrical current of a power circuit of an electric motor, further comprises a first communication system interface for a first communication system, a second communication system interface for a second communication system, and a selecting unit adapted to select whether the switching device is a master or slave in relation to said second communication system. | 03-12-2009 |
| 20130201594 | DRIVING CIRCUIT FOR RELAY - The present invention relates to a driving circuit for relay, which uses N relays with their coils coupled to each other. One of the relays is coupled to a driving power supply. A switching control circuit is coupled to a second relay and a reference voltage for controlling on/off of the plurality of relays. A driving control circuit is coupled to the plurality of relays for controlling excitation of the plurality of relays. After the coils of the relays are excited by the driving control circuit, the voltage of a single coil is dropped to one Nth of the driving voltage. Thereby, the power consumption of the coils of the relays can be reduced, and hence enhancing the lifetime and reliability of the relays. | 08-08-2013 |
| 20150036256 | Method for Design of Subsea Electrical Substation and Power Distribution System - A subsea electrical subsystem and a power distribution utilizing the same. The electrical substation located subsea is electrically connected to AC power provided by a power generator located topside. The electrical substation comprises a plurality of circuit breakers and a circuit breaker operating system associated with each circuit breaker. The circuit breaker operating system is constructed and arranged to operate the associated circuit breaker and is operatively connected to at least one control module. The control modules are electrically connected to a DC power supply located topside. | 02-05-2015 |
| 20150109712 | Adapter for connecting a switch device to a data bus and switch assembly comprising the adapter - An adapter configured to connect a switch device to a data bus, wherein the switch device has a box-like body which houses a switching unit for switching an electric circuit, wherein the adapter includes a case having a first opening and a second opening and an electronic control unit housed in the case and having a first connection element adapted to be connected to the switching unit through the first opening and second connection element adapted to be connected to the data bus through the second opening to convert the electric signals generated by the switching unit into data signals and vice versa. | 04-23-2015 |
