摘要： The invention relates to a DC power distribution system (1) comprising a power supply (50) for supplying DC power to an electrical device (11) like a luminaire, wherein the system includes a connection device (4) comprising a connection device contact (5) to which an electrical device contact (19) of the electrical device is to be connected, a load presence detection unit (7) for detecting whether the electrical device contact has been connected, and a power providing control unit (6) for providing the DC power of the DC power distribution system to the connection device contact, only if the load presence detection unit has detected that the electrical device contact of the electrical device has been connected to the connection device contact. Thus, a voltage is not applied to the connection device contact, if the electrical device is not connected, thereby reducing corrosion effects and the likelihood of installers getting electrified.

摘要： Method and apparatus (1) for the monitoring of electricity that is being transmitted via one or more high voltage lines (19), where the magnetic field from at least one of the high voltage lines (19) is measured as a function of the current that is being transmitted by the high voltage line(s). It is used to measure the magnetic field generated by the high voltage line current and the direction of the current in the high voltage line, same measurement supplied by a single sensor coil device (2) located in the magnetic field, where a 180° phase change in the measured value at a measurement point in relation to an expected phase in the measured value at the abovementioned measurement point causes the signalling (21) of a change in current direction in the high voltage conductor being measured, and information concerning current strength and current direction in the high voltage conductor (19) is transferred to an external central data processing unit (22).

摘要： A test equipment is described which comprises two boards (11, 12). Each board comprises at least one line (13, 14). A sense resistor (15) is provided within the line (13, 14). A first comparator (21) is connected with its positive input to the line (13) on one of the two sides of the sense resistor (15) and with its negative input to the line (14) on the other one of the two sides of the sense resistor (15). A second comparator (25) is connected with one of its inputs to the line (14) on one of the two sides of the sense resistor (15) and with the other one of its inputs being provided with a voltage divider. The first comparator (21) provides an output signal (S) depending on the direction of the current (IR) flowing on the line (13, 14).

摘要： Various circuit configurations for use in switch assembly used in a surgical hand piece system are provided. The circuit configuration provide a number of functions such as permitting the presence and direction of conductivity to be detected. The circuit configurations also provide a means for detecting and measuring the degree of influence of debris which is located between the conductive members of the handpiece. In addition, the circuit configurations also provide a means for identifying the type of switch end cap which is attached to the handpiece. The handpiece body and the switch mechanism are electrically connected to one another in such a manner that permits the switch end cap to be freely rotated about the handpiece body and reduces the number of conductive members needed to communicate the status of each switch.

摘要： A reverse current limited regulator for coupling an input node (NODE A) and an output node (NODE B) for limiting a reverse current through a pass transistor (P1) which connects the input and output nodes. The regulator comprises a voltage comparator (N1, N2, R1) which compares the voltages at the input and output nodes and biasing circuitry (P4, P5) which is controlled by the outputs of the comparator to bias the substrate of the pass transistor with one of the two voltages.

摘要： A measurement circuit in the output circuit of the sensor, for example, determines the polarity of the user circuit applied to its terminals. Whichever of the two states is detected is stored in a storage element and the correct driver is connected to the output terminals. This state persists as long as the polarity of output terminals does not change. If for example the terminals are interchanged when a defective relay is replaced, the measurement circuit corrects the stored state so that the correct driver is also connected to the user circuit. If, for example, sensors for (+) instead of (-) connection are suddenly required when a control card or a control are replaced, the devices need not be interchanged. They are initialized (re-conditioned) when the voltage is switched on and adapted to the new circumstances.
