Abstract: A method for controlling an inlet-adjustment mechanism in an air inlet for a compressor so as to switch the mechanism in a binary fashion between open and closed positions for adjusting a flow area of the inlet. The method includes identifying a threshold line on a compressor map of pressure ratio versus corrected flow rate for the compressor, at which the inlet-adjustment mechanism is switched from one of its positions to the other. A fixed switch band straddling the threshold line can be used for determining when to initiate the switch of positions so as to time the switch to coincide with the operating point reaching the threshold line. Alternatively, a time to reach the threshold line can be instantaneously computed and compared to the actuator/mechanism response time.

Abstract: An example hydraulic tool includes: a fluid reservoir; a pump; an electric motor; a cylinder; a piston; a first trigger button; a second trigger button; and a controller configured to perform operations comprising: receiving a first signal when the first trigger button is triggered, responsively, causing the electric motor to rotate in a first rotational direction, thereby: (i) causing the pump to provide fluid to the cylinder, and (ii) causing the piston to move in a first linear direction, thereafter, receiving a second signal when the second trigger button is triggered, and responsively to the second signal, causing the electric motor to rotate in a second rotational direction opposite the first rotational direction, thereby: (i) opening a fluid path from the cylinder to the fluid reservoir, and (ii) causing the piston to move in a second linear direction opposite the first linear direction.

Abstract: A turbocharger system for an internal combustion engine that powers a vehicle having a pressure vessel storing pressurized air. The turbocharger system comprises a turbocharger and a valve system. The system is configured such that the air intake system of the internal combustion engine can be supplied with air at super-atmospheric pressure either from the compressor of the turbocharger or from the pressure vessel. When the pressure vessel is supplying the intake system, compressed air from the compressor is recirculated back to the air inlet of the compressor so as to help prevent a surge condition in the compressor.
