Abstract: A low voltage amplifier having a class-AB control circuit which generates minimal or no surge current when the output of the amplifier clips to ground or the negative rail. The amplifier includes an input stage, a summing circuit, a class-AB control circuit and an output stage. The input stage connects to a first current source and couples to receive a pair of differential input signals to generate intermediate signals that are summed together using the summing circuit. A second current source supplies the summing circuit with current. The class-AB control circuit receives the summed signals from the summing circuit to provide control for the output stage which generates the amplifier result at the output of the amplifier which delivers current to drive an external load.

Abstract: A fluid-delivery mechanism for a fluid-ejection device includes a fluid-supply station and a bracket that is fluidly and removably connectable between the fluid-supply station and one or more fluid-ejection printheads that are insertable into and controllable by the fluid-ejection device. The bracket supplies fluid from the fluid-supply station to the fluid-ejection printheads.

Abstract: Circuits and methods for dynamically stabilizing a circuit having a relatively small capacitive load two current loop sub circuits are provided. A main current loop and an associated sensing loop are coupled such that a compensation capacitance supplied to each sub circuit loop individually will remain isolated and will not be cumulative with respect to the remainder of the circuit.

Abstract: A cam-operated, rack-on-rack adjustment assembly on a drill pipe spinner allows the user to easily and in small increments (distances) (three-eighths inch, one-quarter inch or less, or more) adjust the effective pipe engaging length of the drive chain. In other words, the effective length of chain wrap (the amount that grips the pipe) given the pipe size can be adjusted.

Abstract: The Vt of an MOS transistor is lowered in response to its load current. In a LDO (low dropout) regulator, lowering the Vt of the pass transistor with load increases the level of drive that can be applied to the pass transistor thus allowing a smaller transistor to be used for the same load.

Abstract: A mat for use in commercial, residential, and/or automotive applications includes a rubber layer comprising rubber particles and a matrix material proximate the rubber particles. The matrix material comprises a barrier material and a binder material. The mat also includes a textile layer thermally bonded to the rubber layer. The textile layer comprises a backing layer comprising polyester. The textile layer further comprises a tufted textile surface coupled to the backing layer.

Abstract: A recyclable ink container, ink container base assembly, and a method of attaching an ink container to a recyclable ink container base are disclosed. The container and ink container base assembly may be formed of recyclable material. A locking nut and needle assembly are part of the base fixture that hold the ink container assembly in place. The needle assembly is independent of the locking nut such that the ink needle and airline properly align when the locking nut is turned.

Abstract: The present invention provides increased output swing by connecting a buffer backgate to an upper rail potential (125) during the no load current condition. This can be done through the use of a comparator (440) and a multiplexer (460), thereby changing the threshold voltage of the buffer (115).
