The logic controller circuit can include analog circuitry that includes a plurality of analog components and trimming circuitry for configuring the analog components. Digital circuitry can be configured to switch between an active mode and a hibernation mode, wherein the hibernation mode consumes less current than the active mode. A voltage regulator circuit can be configured to generate a regulated voltage from a supply voltage.

An increase and a decrease in output of an operation device are controlled along with an increase and decrease in amount of light received by the light receiving element (21b) due to relative movement between the optical sensor (21) and the reflector (22).

According to one embodiment, a control device in a power electronics device includes a controller, a configuration determiner and a manager. The controller performs control associated with power conversion, in accordance with a first logical configuration of control between the power electronics device and other power electronics device. The configuration determiner performs determination processing of a second logical configuration when a change condition of the first logical configuration is satisfied. The manager instructs the controller to perform the control in accordance with the second logical configuration, the manager performing management such that the controller performs the control in accordance with previously given control information for a period after the change condition of the first logical configuration is satisfied and until the manager instructs the controller to perform the control associated with the power conversion in accordance with the second logical configuration.

The supplemental circuit is for a power supply equipped with a power management integrated circuit (PMIC). The supplemental circuit includes a detection circuit producing input signals, a switch, a signal generation circuit producing a control signal controlling the switch's open and close according to the input signals, and a RC circuit. When the switch is closed, the PMIC and the RC circuit are series-connected to ground. The supplemental circuit resolves the reduced performance of the PMIC due to the field effect transistors (FETs) inside the PMIC suffering greater switching loss when the PMIC is constantly series-connected to ground through RC circuit.

An apparatus for monitoring ground current includes a signal generation module that generates a plurality of AC components of different frequencies. An injection module injects the plurality of AC components on one or more phases of a set of power cables connecting a power source to a load. The set of power cables includes an equipment grounding conductor. The AC components are injected in the equipment grounding conductor. An AC detection module that determines an AC current corresponding to each frequency of the AC components present in current in the equipment grounding conductor, an AC threshold module determines if one or more of the AC currents is below an AC threshold, and a trip module opens a contact if the AC threshold module determines that at least one of the AC currents is below an AC threshold. The contact disconnects the power source from the power cables.

A detection device includes: a detector having an inherent detection area to detect entry of a detection target into the inherent detection area; a restrictor for restricting the inherent detection area to a specific set detection area; a body having a detector opening part; a detector fixer for fixing the detector; and a restrictor fixer whose position is fixed to the detector fixer and to which the restrictor is fixed, the restrictor fixer configured so that a relative position between the detector and the restrictor is fixed by fixing a position of the restrictor to the detector fixer via the restrictor fixer. The detector and the restrictor whose positions are thus fixed are assembled to the body so that a circumferential edge of the detector opening part is located outside the set detection area while the restriction of the inherent detection area by the restrictor is maintained.

A method for transmitting electrical energy is proposed in which between two electrical units electrical current is transmitted by means of a superconductive cable system (4). The two ends of the superconductive cable system (4) are each connected in a current conducting manner to one of the electrical units. A normally conductive cable system. (5) is arranged parallel to the superconductive cable system (4). The function of the superconductive cable system (4) is monitored by a control unit (10). During normal operation. only one end of the normally conductive cable system (5) is connected in a voltage conducting manner to one of the electrical units. In case of a malfunction of the superconductive cable system (4), a first signal (12) of the control unit (10) initially connects the other end of the normally conductive cable system (5) to the other electrical unit, so that the normally conductive cable system (5) becomes current conducting, and the superconductive cable system (4) is subsequently switched off by at least one of the electrical units.
