  • Patent number: 10269789
    Abstract: A protection circuit for an integrated circuit product die or die-let (die-let) is responsive to whether the die-let has undergone a dicing operation or not. A test circuit on the die-let's semiconductor wafer can test and/or configure the die-let. After the dicing operation, the protection circuit generates a signal to isolate the cut input lines from the test circuit to prevent any interference with the normal operation of the integrated circuit product die-let.

  • Patent number: 10103732
    Abstract: A low power voltage level shifter circuit in which current is limited through at least one of a plurality of CMOS logic circuits, one of which receives input signals within a first voltage level and is connected between a first upper and lower power supply, a second of which transmits shifted output signals within a second voltage level and is connected between a second upper and lower power supply. There is at least one current-limiting MOS transistor connected between at one of the CMOS logic circuits and one of its power supplies. Typically, there is at least one current-limiting MOS transistor between the second CMOS logic circuit which transmits the shifted output signals which have a larger range than that of the input signals. A second current through the at least one current-limiting MOS transistor mirrors a set current through a first MOS transistor so that power consumed by the CMOS logic circuit during switching is limited.

  • Patent number: 10001464
    Abstract: An apparatus including a screen capable of separating solids from a liquid-solid mixture and a first probe disposed beneath the screen. The first probe is provided to determine a position of a beach between the liquid-solid mixture and separated solids. The apparatus may measure a property of a local volume of a probe disposed beneath a first separator deck. The probe may then send a first signal to database. Based on the signal a location of a beach may be determined.

  • Publication number: 20180130514
    Abstract: An MTP (Many Times Programmable) memory cell for integrated circuit memory arrays is described. The cell includes an MTP device and a thyristor interconnected so that the MTP device triggers the thyristor to turn on during a Read or Verify operation. The difference in threshold voltages between a data memory cell and a reference memory cell is used to determine the information in the data memory cell. Different memory cell structures may be constructed for different memory array requirements.

  • Publication number: 20170320099
    Abstract: A method, apparatus and system for flowing a fluid from an inlet flush nozzle onto tiered plates in a trough is provided. Material may fall from a deck in a vibratory separator, such as a shale shaker, into the trough, which is attached to the separator. The trough has a main inlet and the inlet flush nozzle that opens to tiered plates. An external pipe may feed the fluid into the main inlet and the inlet flush nozzle to lubricate the tiered plates in the trough. Material falling from the vibratory separator may float on the fluid to flow toward an outlet of the trough. A single plate with perforations may be used instead of the tiered plates to permit the fluid to penetrate the perforations to suspend the material, allowing the material to flow across the single plate to an outlet.
