Patent CA-2519138-A1 (CA)
Title: A backpack for harvesting electrical energy during walking and for minimizing shoulder strain
Inventor: ROME LAWRENCE C
IPC: F03G3/02
Filed: 2004-03-17
Abstract: A suspended-load backpack designed to permit the load to move relative to the backpack frame during walking and running so that the large movements between the load and the frame of the backpack reduce the fluctuations of absolute vertical motion of the load. Because the hip (and thus the pack frame) go up a down a good deal during walking, a large relative movement between the frame and the load reduces the absolute excursion of the load. This movement may be, in turn, transferred to a motor through, for example, a rack and pinion gear, to convert the mechanical movement to electrical energy. The movement may also be converted to electrical energy by using an electroactive polymer (EAP) to connect the suspended load to the frame. Such designs allow the load to move in a controlled fashion to prevent the patient from losing his or her balance as the load moves up and down along the backpack frame. Such movement of thesuspended-load relative to the frame also reduces the forces on the wearer's shoulders while walking or running, thus reducing the likelihood of orthopedic injury.

Abstract: Aircraft landing gear comprised of a wheel hub motor/generator disks stack, includes alternating rotor and stator disks mounted with respect to the wheel support and wheel. The invention can provide motive force to the wheel when electrical power is applied, e.g. prior to touch-down, thus decreasing the difference in relative velocities of the tire radial velocity with that of the relative velocity of the runway and reducing the sliding friction wear of the tire. After touchdown the wheel hub motor/generator may be used as a generator thus applying a regenerative braking force and/or a motorized braking action to the wheel. The energy generated upon landing maybe dissipated through a resistor and/or stored for later use in providing a source for motive power to the aircraft wheels for taxiing and ground maneuvers of the aircraft. Methods and apparatuses for nose gear steering and ABS braking using the disclosed invention are described.

Title: Protective-apparel sleeve and protective apparel incorporating same
Inventor: BUSHMAN BRADLEY J
IPC: A41D13/12
Filed: 2005-08-24
Abstract: A protective-apparel sleeve (10) includes a tubular inner piece (12) of membrane laminated or coated fabric and a tubular outer piece (14) of membrane laminated or coated fabric generally surrounding the tubular inner piece (12). In further detail, the tubular inner piece (12) includes a stitched seam (24) along its length, and the tubular outer piece (14) includes a stitched seam (26) along its length which is circumferentially offset from the seam (24) of the tubular inner piece (12). If desired, the stitched seams (24, 26) may be generally free of a seam sealant. The protective-apparel sleeve (10) and protective-apparel products incorporating the sleeve (10) have a significantly greater liquid-resistance than conventional stitched-seam protective-apparel sleeves and protective-apparel products incorporating such sleeves. This enhanced liquid-resistance is achieved without a significant increase in acquisition costs, processing costs, and sleeve weight, and without sacrificing the comfortable feel typically associated with stitched-seam protective-apparel sleeves and protective-apparel products incorporating such sleeves.
