Abstract: Pressure regulators find uses in a variety of applications such as, for example, pneumatic tools, water systems, and paintball markers. Pressure regulators may substantially benefit from a separate seal carrier adapted to facilitate maintenance, improve performance, and open independent of piston movement; poppet bypass bores to increase regulated fluid flow; and, an outlet poppet adapted to operate independent of the piston.

Abstract: An integrated circuit includes a testable delay path. A transition of a delay path input signal causes a subsequent transition of a delay path output signal. A pulse generator receives the delay path input and output signals and produces a pulse signal having a pulse width indicative of the delay between the delay path input and output signal transitions. A delay line receives the pulse signal from the pulse generator. The delay line generates information indicative of the pulse signal pulse width. The delay line may include multiple stages in series where each stage reduces the pulse width of the pulse signal. The delay line may include a high skew inverter having PMOS and NMOS transistors having significantly different gains. The pulse generator is configured to produce a positive going pulse signal regardless of whether the delay path is inverting or non-inverting.

Abstract: An on-off controller, according to various aspects of the present invention, for controlling a flow of fluid from a provided bottle, wherein the bottle has a poppet valve biased in a closed position, wherein fluid flows from the bottle when the poppet valve is open. The on-off controller includes a body, a bore, an activator, and a position mechanism. The body includes an axis and an inlet. The inlet is positioned axially and couples to the bottle. The bore is formed through the body. Each end portion of the bore is open at the exterior of the body and the bore is not parallel to the axis. The activator includes a depressor that opens the poppet valve, a position connector, and at least one pin disposed between the depressor and the position connector. The activator does not obstruct the bore. The position mechanism moves the activator.

Abstract: A coupler enables a paintball hopper to be easily connected to and disconnected from a paintball marker. A part of the coupler is connected to the paintball marker while another part is connected to the paintball hopper. The coupler has a locked and an unlocked position. In the unlocked position, the portion of the coupler connected to the paintball hopper is easily removed from or inserted into the coupler. In the locked position, the paintball hopper is held immobile and capable of being used in a competitive environment. The coupler provides fixed positions while locked and uses techniques to keep the hopper immobile when locked to the paintball marker.

Abstract: Methods and apparatus for regulating fluid pressure are described. A fluid regulator with relatively large passages and a high-pressure reserve may improve performance when the regulator is used in a sustained sequence. A smaller area stem piston may make the regulated pressure more independent of the input pressure.

Abstract: Speech Label Accelerators (SLAs) are provided that comprise an indirect memory, atom value memory, and adder circuitry. Optionally, the SLAs also comprise an accumulator, a load/accumulate multiplexer (mux), and a control unit. There are a variety of different configurations for the adder circuitry, and a configuration can be selected based on speed, power, and area requirements. A number of techniques are provided that allow a system having an SLA to handle more dimensions, atoms, or both than the SLA was originally designed for. A “zig-zag” method is provided that speeds processing in a system when using more dimensions than the SLA was originally designed for. Generally, the kernels used by the SLA will be Gaussian and separable, but non-Gaussian kernels and partially separable kernels may also be used by the SLA.
