摘要： An apparatus for calibrating rotary power assembly impulse tools comprises a variable rate simulated test joint in which a rotary shaft is braked by brake shoes in direct contact with the shaft under the control of a computer. The braking torque applied to the shaft by the brake shoes is gradually increased while the shaft is driven at free-running speed by the tool being calibrated, and the pulsed output of the impulse tool is monitored. The monitored pulsed output is initially erratic, but settles down to a regular stream of output pulses. The first pulse of that regular stream can be identified. The magnitude of the braking torque is then increased as a linear function of time with a predefined gradient representative of the torque rate of the joint being simulated, commencing with the identified first pulse. The apparatus is the first such apparatus to be able to provide thoroughly reliable and consistent torque calibration for impulse tools.

摘要： A torque transducer has a torque transformable shaft 2 with strain gauges 10, 12 electrically connected to sliprings 58 separated by spacers 60. A torque related signal is transmittable via the sliprings to a brush arrangement 22 having flexible strips 24 pulled by tension from springs 26 against the periphery of the sliprings 58, with the strips 24 tracked between the spacers 60 onto the sliprings 58.

摘要： An electrical connector including an insulator and a number of contacts for mounting on a substrate such as a printed circuit board. As disclosed, the electrical connector includes an elongated insulator block carrying contacts in the form of pins, an end of each of which is received in a printed circuit board aperture to be soldered to the printed circuit board. The elongated insulator block further includes a series of holes, each intermediate an adjacent pair of contacts of the connector, precisely located relative to the contact locations, to facilitate positioning the connector for insertion of the pins into a printed circuit board. The insulator block is notched adjacent each of the holes to facilitate breaking the connector to a desired length, and hence containing a desired number of contacts. The insulator block further has generally semi-cylindrical indentations at each of its ends. To mechanically secure the electrical connector to a printed circuit board, prior to soldering of the contact pins thereto, a peg is inserted through one of the holes in the insulator into gripping engagement with the walls of an aperture in the printed circuit board.

摘要： Systems and methods that provide control circuits having multiple sub-control inputs that control operation of a power electronics device (e.g., a power converter). Each of the multiple sub-control inputs are output from a separate sub-control circuit that includes a feedback circuit having an input tied to a common control node. The common control node is coupled to an input of a controller (e.g., a PWM controller). Outputs of each of the sub-control circuits are coupled to the common control node by a respective switch (e.g., diode, transistor, etc.) so that each of the sub-control circuits may be selectively coupled to the common control node to provide a control signal to a controller. Since components of each of the feedback compensations circuits are biased at a regulation voltage instead of a higher power supply voltage, the control circuit may switch between control modes with minimal delay.

摘要： An electronic click wrench comprises a handle for applying torque through a shaft to a working head. The shaft includes torque sensing means for calculating the torque applied to a workpiece by the working head, and a trigger mechanism for sending a haptic feedback to a user by triggering a small movement of the handle relative to the working head when a set point torque is reached. The trigger mechanism comprises a permanent magnet that is normally anchored by magnetic attraction to a pole piece so as to resist separation when a force is applied through the handle, and an electromagnetic means actuable to reduce or cancel that magnetic attraction so as to permit separation of the pole piece and permanent magnet, thus generating the haptic feedback. Operation of the electromagnet may oppose the flux of the permanent magnet through the pole piece. Alternatively operation of the electromagnet may divert the flux of the permanent magnet away from the pole piece.

摘要： A power converter has a transformer having three primary windings configured to receive respective phases of a three-phase alternating current (AC) input signal in a delta configuration and three secondary windings, each split into two portions, wherein the portions are coupled together in a regular hexagon. The power converter includes a rectifier having a first rectifier path coupled between taps of the secondary windings and a positive output of the power converter and a second rectifier path coupled between taps of the secondary windings and a negative output. One of the secondary windings may be reversed with respect to the other secondary windings. The primary windings may be split with a corresponding secondary winding sandwiched between portions of the primary. One of the paths may have a different inductance than the other path.

摘要： A dual compensation operational amplifier is suitable for use in an environment that experiences fluctuations in ambient energy levels. A dual compensation impedance can be determined to nullify or compensate for effects of an input offset voltage or an input bias current or both. Adjustments to the dual compensation impedance can be made based on calibration data for various environmental conditions so that the dual compensation impedance can be either pre-set for anticipated conditions in different target operational environments, or automatically adjusted in-situ. Target operational environments that may benefit from such a dual compensation impedance include remote areas that experience extreme or variable temperatures, high altitudes, space, or high radiation environments.

摘要： A transformer may include a first and a second continuous single piece multi-turn helical winding, one concentrically received by the other. The turns of the windings are electrically insulated from one another and spaced sufficiently close together to permit inductive coupling therebetween. The turns may be formed of a conductor having a rectangular cross-section, which may, or may not, include an electrically insulative sheath. The single piece multi-turn helical windings may have a continuous or smooth radius of curvature, with no discontinuities or singularities between first and second end terminals. The transformer may be formed by wrapping electrical conductor about a winding form. The transformer may be used in various electrical circuits, for example converter circuits.
