摘要： A current sourced control topology is provided for an AC motor controller that eliminates many of the problems associated with prior art motor controllers that use voltage source inverter (VSI) technologies. By controlling the output of AC current sources such as synchronously controlled down converters to directly drive each motor phase, significant efficiency gains and a reduction in electromagnetic interference is achievable.

摘要： Systems and methods are provided for assigning unique addresses to multiple slave devices (12) on a network implemented in a star configuration, having individual power (28) and/or data (14) buses connecting the slave devices (12) to a master device (16). A switching circuit (26) on the master side (16) of the system is used to allow a unique address to be assigned to one slave node (12) at a time. A control circuit (34) determines the state of the switching circuit (26) and directs the master device (16) to re-address each slave node (12) at the appropriate time, so as to assign a unique address.

摘要： Disclosed is a system for aiding in determining when a power-providing outlet is ending its usable service life and is due for service or replacement. A connection detection unit (102) and counting unit (103) respectively monitor connection of a device to a port (101) and maintain a connection count of connection events. For USB type C connections a cable or device resistance detection circuit can be used to determine if a USB type C device or cable has been connected. USB Type A and AC connections can be detected by mechanical or electrical mechanisms. When a connection has been detected a counter can be incremented or decremented to record a connection. A limit value can be set and compared to the connection count and a sensory or electronic indication can be made when the limit value is exceeded.

摘要： PROBLEM TO BE SOLVED: To provide an electric machine and a method for practically limiting a short circuit current so as to prevent thermal damage by the short circuit current in the electric machine. SOLUTION: The electric machine is composed of a rotor structural component, and a stator structural component adjacent to the rotor structural component, when arranging winding in a plurality of teeth of the stator structural component. A coil is wound so that currents flowing through at least a pair of coils flow in the same direction in the same slot, and another coil is wound so as to offset magnetic coupling in another phase so that a current flowing through the coil induces mutual impedances upon a short circuit, and the total impedance is increased. Consequently, the increase of the short circuit current upon the short circuit is prevented, and the redundancy is maintained between different phases so as to attain a construction in which the short circuit in one phase does not affect the other phases.

摘要： A method which allows for the quick and accurate detection of faulty operating conditions and bad interconnections between and within devices in an electrical system. The method allows for the detection of arcing in wiring and components, high resistance connections, loose components, and the like. Voltage or current at each end of a conductor, or on each side of a system component, or the current through a component, may be detected and analyzed. A fault or abnormal condition is indicated when the voltage or current exceeds an expected level. Alternatively, resistance may be detected and analyzed, and a fault condition indicated when the resistance exceeds an expected level. Existing detection or computation equipment already associated with the system may be used for the detection and analysis.

摘要： Detecting contact bouncing in a contactor by measuring contact voltage fluctuations caused by bouncing power delivery contacts controlled by the contactor. When fluctuations are detected, a circuit causes a pull-in coil of the contactor to be temporarily re-energized to re-establish a higher magnetic field needed to pull and maintain the power delivery contacts into proper position, eliminating bounce. High power required by the pull-in coil, a time actuated is limited to avoid thermally damaged coil or other electronic components. Activation of the pull-in coil position the power delivery contacts properly, energizing a lower magnetic field hold coil maintains the power delivery contacts position. The time that the pull-in coil is activated may be dynamic and correspond to each disturbance as it happens, it may be a set time determined by a timer, or it may be controlled by a Pulse Width Modulation scheme.

摘要： An outlet modular enclosure (OME) (28) is configured to receive a compatible Snap-In / Snap- Out (SISO) outlet unit (30). The outlet modular enclosure (28) includes an electrically conductive housing with a first aperture sized to receive the outlet unit (30) and a second aperture sized to receive a wire harness. The electrically conductive housing forms at least a portion of a Faraday cage around the outlet unit (28). The modular unit (MOU) assembly includes the OME (28) and a compatible Snap-In / Snap-Out (SISO) OU (30) with a front side faceplate (52). The opposing rear side of the SISO (30) is receivable within the first aperture of the OME (28), while a wire harness adapted to deliver power and data to the OU (30) is received by the second aperture. The wire harness has an electrically conductive shield overbraid (38) at a first end thereof that is electrically connectable (39) to the outlet modular housing (28).

摘要： A planar transformer includes a magnetic core (22) having an internal opening. A plurality of high current capacity windings (34) are disposed within the internal opening. These high current capacity windings (34) have a length, a width and a thickness. Each winding is formed as an open loop having adjacent first and second end portions. There is at least one primary winding and one secondary winding. The primary winding and/or secondary winding may be high current capacity windings. A first terminal lead (30) is electrically interconnected to multiple adjacent first end portions and a second terminal lead is electrically interconnected to multiple second end portions. Both the first terminal lead (30) and said second terminal lead have a length, a width and a thickness measured with the thickness being less than either the terminal lead length or the terminal lead width.

摘要： Disclosed is a Personal Electronic Device (PED) positioning apparatus that stows within a tray table. An articulated holder includes a crossbar arm that slides on at least one support shaft to a position where a crossbar can be rotate to provide an angled surface relative to the tray table to support a PED. When stowed, the crossbar presents a minimal profile with respect to the tray table. The exposed surface of the crossbar can be made to match the color and appearance of the tray table so that the apparatus has minimal visual impact.
