A medication infusion system may include a controller and a reservoir module including a reservoir containing medication to be delivered to an internal wound site via the controller. The controller may have a peristaltic pump driven by a motor to urge medication to flow toward the internal wound site, through a conduit. A blockage sensor disables the motor and provides an alarm if the tube is blocked. The blockage sensor detects distention of a preferentially distendable portion of the tube, which may be routed about a constraining member. When blockage occurs, the tube distends preferentially along a direction generally parallel to the radius about which the tube bends. The blockage sensor may include a variety of switching elements, such as a pushbutton switch, a metal ring encircling the tube to make contact between conductors, and/or a metal bridge bendable to make contact between conductors.

System and method for blockage detection for medication infusion

An apparatus for a self-cleaning litter box having a control system for a mechanical self-cleaning mechanism. The litter box has a turret carrying a rake. The box includes an animal sensor that detects the presence of an animal in the box. A specified time after the animal leaves the box, the turret sweeps the rake through the litter, picks up the collected waste, and carries it to a waste bin, where the waste is dumped. The litter box is controlled by a processor executing a software program that monitors the instruments and sensors and controls the turret and rake motors. The software, in various embodiments, controls the rake motor and turret motor to execute a scoop sequence, a startup sequence, and a go home sequence.
