A system and method to control operation of an air compressor of a vehicle is disclosed. The system may include a transceiver and a processor communicatively coupled with each other. The transceiver may be configured to receive vehicle information from a vehicle control unit. The vehicle information may include a vehicle type and real-time vehicle operational parameters. The processor may obtain the vehicle information from the transceiver and determine that a predefined condition may be met based on the vehicle type and the real-time vehicle operational parameters. The processor may further control an air compressor operation based on the vehicle type and the real-time vehicle operational parameters, responsive to determining that the predefined condition may be met.

A manually operable pump for cooperation with a container to reduce pressure inside the container; the pump comprising, a cylinder having a lower end for cooperation with the container, a piston movable inside the cylinder, a closure element arranged around a lower end of the piston, wherein the closure element comprises a bottom and a wall surrounding the lower end of the piston, wherein the bottom is adaptable between a rest position wherein a pressure difference over the bottom is lower than a predefined threshold and an indicator position when the pressure difference equals or exceeds the predefined threshold.

Systems and methods for a compressor system are provided for selectively operating the compressor system with reduced power consumption. An output demand level of the compressor system can be monitored over time to identify a demand profile. A pressure setpoint for the compressor system can be selectively adjusted based on the demand profile, including to selectively transition between an operational pressure setpoint for an active demand profile and a reduced pressure setpoint for an inactive demand profile.

A method includes measuring a fluid pressure of fluid in a fluid supply line of an infusion pump. The fluid pressure includes a motor pressure and a patient pressure. The method also includes determining the patient pressure. The determining includes removing, by an adaptive filter, to remove the motor pressure from the measured fluid pressure. The removing includes generating a predicted motor pressure based on the current of the motor, generating an error signal based on a comparison between the predicted motor pressure and the measured fluid pressure, and removing the motor pressure from the measured fluid pressure when an error value indicative of the error signal is less than an error threshold. The method also includes adjusting, based on the patient pressure, a setting of the infusion pump. Related methods and articles of manufacture, including apparatuses and computer program products, are also disclosed.

A pistol-grip style tool that includes an air pump driven by an electric motor, and a trigger operably coupled to the motor to operate the motor. The tool may also include a reservoir that removably couples to the air pump, and be adapted to receive a removable power source, such as a battery pack. The tool may be used to perform tests and diagnostics on systems or parts within a vehicle or other machine.
