Abstract: A microminiature electro-magnetic coil sensor pull ring with a pull wire attached thereto is used in changing the angle of a distal end of a medical catheter. The tubular pull ring has a connection recess with a flat bottom machined into the full wall thickness and located proximal to a coil wrap area. Circuit wires are electrically connected to the two lead ends of the coil within the connection recess, such that neither the circuit wires nor the lead ends stand proud of the full wall thickness. The coil wrap area is also recessed, and can have side walls defining an offset angle for the turns of the coil. In another aspect, a coil is wound around one of the pull wires for the pull ring.

Abstract: A system of locking a door is disclosed. The system according to the present invention comprises a releasable keeper that secures a door locking mechanism to keep a door secured to an enclosure in a locked position. A release mechanism that is operated from the interior of the enclosure releases the releasable keeper from the enclosure and enable the door to be opened and prevents people from becoming trapped within the enclosure by a locked door. In an exemplary embodiment, the release mechanism is operated by a lever that operates a pulley system to disengage the release mechanism from the releasable keeper.

Abstract: An escape hatch for use with an enclosure such as a tractor trailer is disclosed. The escape hatch comprises an opening defined by the body of the enclosure and a door that is secured to opening by an opening mechanism and a latch mechanism. The escape hatch prevents people from becoming trapped in an enclosure and provides a safe route of escape should a person inadvertently be locked in the enclosure.
