摘要： A T-shaped member is pivotally mounted to a support plate, and has first and second shape memory wires attached at first ends thereof to opposing portions of the T-shape. Second opposing free ends of the shape memory wires are secured to the support plate. Electrical current is conducted alternately through the first and second shape memory wires to cause the wires to contract in alternating tandem, to thereby cause the T-shaped member to move between first and second positions. Pivotal movement of the T-shaped member can be used to actuate and/or reactivate a switch device.

摘要： An eccentric-motion motor for driving a utilization mechanism includes a stator defining a closed surface pathway, an armature composed of a permanent magnet rollably disposed on the closed surface pathway, a series of electromagnetic elements disposed in the stator along the closed surface pathway, circuitry for successively energizing the electromagnetic elements to cause them to attract and/or repel the armature so that it rolls along the closed surface pathway, and a coupler mechanism for coupling the armature to the utilization mechanism so that as the armature is caused to roll, the utilization mechanism is powered by the operation of the motor.

摘要： A resilient sheet of material having a centrally-located aperture having a pump shaft slidably disposed through the aperture to form a sphincter seal therebetween. An inlet conduit leading from a fluid source (an IV bag) passes through the housing into the cavity near the open end thereof, and an outlet conduit leading to a fluid sink (the patient) passes through the housing from the cavity near the closed end thereof. The shaft is driven back and forth in reciprocating motion inwardly and outwardly of the cavity to produce, respectively, a positive pressure forcing fluid out of the outlet conduit to the fluid sink, and a negative pressure forcing fluid from the fluid source through the inlet conduit.

摘要： Linear displacement and strain measuring apparatus includes a linearly movable element, an emitter disposed on the movable element to move as the element is moved, for developing predetermined paterns of electric fields which vary linearly on the emitter in the direction of movement of the element, and a detector disposed in close proximity to the emitter adjacent the path in which the emitter moves to detect variations in the electric field patterns as the emitter is moved, for producing output signals representing variation in the electric field patterns and thus the linear displacement of the movable element relative to the detector. By attaching the movable element and the detector to spaced apart locations on a specimen, strain in the specimen can be measured.

摘要： Apparatus for delivering fluids to blood vessels, body cavities and the like, includes a resilient tubular wire for threading lengthwise into the lumen of a catheter and out the distal end thereof to a target location of a body passageway to be treated. The tubular wire has a central lumen and a distal end formed into a coil, which, when straightened, may be threaded lengthwise through the catheter, but when extended out the distal end of the catheter at the target location, resumes its coiled shape. The tubular wire includes openings at least on the outside of the coils for discharging radially outwardly medication carried in the lumen of the wire. In this manner, the medication may be directed toward the wall of the passageway to infuse a diseased area being treated.
