Abstract: A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen.

Abstract: A rotary knob for operating an electronically actuable deadbolt is described herein. According to some embodiments, the rotary knob includes a chassis, an outer wall rotatably coupled to the chassis about a central axis of the knob, a cantilevered beam attached to an inner surface of the outer wall and extending towards the central axis of the knob such that the beam is configured to rotate with the outer wall about the central axis, a circuit board coupled to the chassis, the circuit board including signal traces, and an electrical contact extending from the cantilevered beam in a direction toward the signal traces and electrically connectable with the signal traces. A controller of the rotary knob is configured to determine a position of the deadbolt based on at least the state of the electrical connection between the electrical contact and the signal traces.

Abstract: A two-wheel movable platform, carrier, or base having canted wheels is disclosed. In one embodiment, the two-wheel movable platform, carrier, or base includes adjustable canted wheels in which the angle of the canted wheels is adjustable. In this embodiment, the two-wheel movable platform, carrier, or base includes a pair of wheel assemblies mechanically coupled to a battery housing. Each of the wheel assemblies includes, for example, a mounting plate, a drive motor arranged in a motor housing, a canted wheel that is driven by the drive motor, and an angle-adjusting motor for adjusting the angle of the canted wheel. In another embodiment, the two-wheel movable platform, carrier, or base includes canted wheels that are set at a fixed angle.
