Abstract: In some illustrative embodiments, an incoming signal from a transducer (110) in an ultrasound imaging beam-former apparatus (100) is applied to an in-phase sample-and-hold (120) and a quadrature sample-and-hold (130). The quadrature sample-and-hold (130) may be clocked a quarter period behind the in-phase sample-and-hold (120). The output of the sample-and-holds are applied to in-phase and quadrature analog-to-digital converters (126). A magnitude calculator (138) receives the in-phase and quadrature digital values, and outputs a magnitude. A phase calculator (142) receives the in-phase and quadrature digital values, and outputs a phase. An apodizer (146) applies a difference between an amplitude of the outgoing signal and the magnitude and applies a first illumination (150-1) to a image point (154) in substantial proportion to the difference, and a phase rotator (152) applies a second illumination (150-2) to the image point (154) in substantial proportion to the phase.

Abstract: A venturi-based vacuum system that provides a compensated vacuum supply to a vacuum utilization device. The system creates a vacuum by means of a source gas passing through a standard venturi with a flow control valve controlling the flow of that source gas and thus, the level of vacuum produced. A feedback system is provided that makes the vacuum system self-compensating. The feedback system senses the level of vacuum in a vacuum supply outlet to the vacuum utilization device and uses that sensed level to control the setting of the flow control valve. As such, changes in flow in the vacuum utilization device that result in changes in the vacuum level from the vacuum system are compensated for by a corresponding change in the setting of the flow control valve to maintain the vacuum level at a constant level.
