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 power tool includes a tool head, a frame that rotationally couples with the tool head, a piston, and a motor that is operable to drive the piston to perform an operation on a workpiece. The power tool also includes a sensor that senses movement of the piston to provide sensor information indicative of the movement of the piston. The power tool further includes a controller that receives the sensor information from the sensor. The controller operates the motor to perform work on the workpiece until the sensor determines the piston has moved a target distance.

Abstract: A writing implement is configured to dispense material onto a work surface. The writing implement includes a body having a first end, a second end, and an inner surface. The writing implement also includes a nib coupled to the first end. The nib is configured to allow the material to be dispensed onto the work piece. The writing implement further includes a pressure regulating assembly coupled to the body. The pressure regulating assembly and the inner surface define a cavity configured to hold the material. The pressure regulating assembly is moveable relative to the body in response to a pressure change within the cavity.
