Abstract: A method responds to an over-temperature condition in a printhead. The method includes generating a first electrical signal corresponding to a temperature in a printhead, monitoring the first electrical signal with a first electronic circuit to terminate delivery of electrical power to a printhead in response to detection of a safety event, and monitoring the first electrical signal with a second electronic circuit to regulate an amount of electrical power delivered to the printhead.

Abstract: A device and method for facilitating the insertion, manipulation and removal of an endoscopic medical device within a body cavity is disclosed. The device may comprise a body portion and a lining. The body portion may be configured to wrap around the outer surface of the insertion tube. The body portion may comprise an outer surface, an inner surface, two ends, and a longitudinal slit extending from one end of the body portion to the other end. The lining may be attached to the interior surface of the body portion. The lining may comprise an at least partially raised surface that contacts the outer surface of the insertion tube at least when a user squeezes the body portion of the device.

Abstract: An endoscopic device for retrieving an object from within a human body is disclosed. The device includes a support assembly, a transmitting assembly, a wire, and a net element. The support assembly has a base and a tubular member. The transmitting assembly includes a handle and a motion transmitting link fixed to the handle and extending through at least a portion of the tubular member. The wire defines a loop portion and two leg portions. A proximal end of each leg portion is secured to the link by a first connection and the two leg portions are secured to each other by at least a second connection distal from the first connection. The net element has a distal portion secured to the loop portion and a proximal portion secured relative to the leg portions. The loop portion is movable between an expanded position and a collapsed position.
