Abstract: A door having a pneumatic sensing edge is operated automatically to open when an object and the edge make contact. An optical pressure switch in fluid communication with gas forced from the edge on contact with the object initiates the operation of a door opener. The optical pressure switch includes a membrane having a portion that interrupts a light beam when the membrane flexes due to the increase gas pressure over ambient pressure as gas is forced from the edge.

Abstract: A helmet includes a head enclosure with an open cavity for the head of a user and a shock detector attached to the head enclosure that provides a signal when the head enclosure is subjected an impact exceeding a predetermined level.

Abstract: A wheel board vehicle includes a frame having thereon a centrally mounted planar board on which a rider stands while riding the vehicle. At a front end of the frame a single support arm extends that has an outer end to which a front yoke is pivotably attached. The front yoke carries a front wheel. At a rear end, stationary support arms carry a rear wheel. A manually operated brake member is attached to the frame near the rear wheel adjacent a leg of the rider while the rider is riding the vehicle, and a stationary handle is attached to the frame and oriented generally vertically while the rider rides the vehicle.

Abstract: A door structure for a vehicle has a door seated in a door jam frame at the rear end of the vehicle. The door jam fame has a first upright with an opening therein disposed nearby one side of the vehicle to provide a space between this side and the first upright. A second upright is nearby the other side of the vehicle. A hinge member is attached to the door which includes a first connecting member attached to the door member near the one side of the vehicle, a second connecting member pivotally attached to the first upright and disposed in the space between the one side of the vehicle and the first upright, and an intermediate arcuate member connected between the first and second connecting members which extends through the opening in the first upright.

Abstract: A vehicle (10a) includes an elongated opening (35) defined by a frame (33) in a side (30) of the vehicle. The opening (35) receives therein a window pane (34) and a seal (40) is positioned in the space between the frame (33) and the window pane (34). The elongated opening (35) has opposed ends with side panels (38) adjacent the ends of the opening (35) and positioned so that an end portion of each panel overlies the opening. Disposed between an interior surface of opposed end portions of the window pane (34) and the end portion of the panel overlying the opening (35) is an essentially opaque material. There is at least one lamp (32) attached to the window pane (34) directly on an exterior surface of the end portions of the window pane (34) opposite the end portions of the panel (38).

Abstract: A method of designing and manufacturing a magnetic separation apparatus. Past separators generally had poor power efficiency, poor throughput performance, and/or were bulky. Designing the magnetic separator of the present invention involves selecting a diameter and height for a separation container and superconducting coil by optimizing at least one parameter from a group of parameters. The magnetic separation apparatus includes a superconducting electromagnet and separation container having a diameter of about 60 inches, a height of about 40 inches, an inlet port, an outlet port, and removable matrix modules. The electromagnet generates a magnetic field strength within the separation container of greater than 3 Tesla. The optimized separation container volume, the high magnetic field strength, and the matrix modules allow the magnetic separation apparatus to have greatly increased slurry processing capacity.

Abstract: A personal vehicle loading and unloading apparatus includes a support structure mounted to a platform such as a truck bed which supports the personal vehicle, and a moveable ramp mounted telescopically within the support structure. The ramp is manually moveable between a retracted position where substantially the entire ramp is within the truck bed and an extended position where substantially the entire ramp extends from the truck bed. The ramp and the support structure each have an upper surface over which the bottom surface of the personal vehicle, or a conveyor for the vehicle, rides as the personal vehicle is moved to and from the truck bed. These upper surfaces each comprise an anti-friction material having a kinetic friction coefficient no greater than 0.5. A winch mechanism mounted to the support structure pulls the personal vehicle into the truck bed during loading and lowers slowly the personal vehicle from the truck bed during unloading.

Abstract: A respiration monitor includes a sensing element having a pressure chamber filled with gas. The sensing element is adapted to be placed in contact with a breathing subject, with the pressure in the chamber increasing as the subject inhales and decreasing as the subject exhales. A pressure switch in communication with the pressure chamber opens as the subject exhales and closes as the subject inhales to control the operation of a timing circuit. The timing circuit includes an audio alarm mechanism activated when the switch is not closed within a predetermined threshold period. The chamber has at least one gas port which places the chamber in communication with ambient air pressure, so that within a pressure equalization time interval the pressure within the chamber equalizes to that of ambient air pressure and the switch is opened.
