  • DEFECT DETECTOR IN POWER DISTRIBUTION SYSTEM
    Publication number: 20210239760
    Abstract: A defect detector can receives voltage data characterizing a three-phase voltage for each of a plurality of feeder lines. The defect detector generates an alert indicating that a potential defect exists at a switch upstream of the plurality of feeder lines in response to the voltage data indicating (i) a drop in two or more phases of voltage at a given feeder line of the plurality of feeder lines occurred within a predetermined amount of time of toggling of the switch or (ii) a drop in two or more phases of voltage on at least two or more feeder lines of the plurality of feeder lines has occurred.

  • Apparatus and method for automatic pitch conversion of pick and place heads, pick and place head and pick and place device
    Patent number: 9776334
    Abstract: An apparatus for automatic pitch conversion for pick and place heads, comprising at least one auto pitch station for adjusting a pitch in a X-coordinate direction and/or adjusting a pitch in a Y-coordinate direction of pickers/grippers of a pick and place heads; a first actuator, operated by a motor gear assembly of the at least one auto pitch station, wherein the first actuator changes the pitch in the X-coordinate direction distance between rows of pickers/grippers of the respective pick and place head; and a second actuator operated by the same motor gear assembly, wherein the second actuator changes the pitch in the Y-coordinate direction between the pickers/grippers within a row of the respective pick and place head. A method for automatic pitch conversion of pick and place heads and a pick and place head and a pick and place device.
