Abstract: A device includes a harness system configured to be attached to a parachute harness of a parachute. The device also includes a propulsion system connected to the harness system, wherein the propulsion system is configured to be off when undeployed and during freefall, and wherein the propulsion system is configured to deploy during canopy flight stage to generate thrust for a parachutist of the parachute. The device further includes a circuitry configured to control power generation by the propulsion system to control the thrust. The device includes a power source configured to power the circuitry and the propulsion system.

Abstract: An optical fiber cable includes a cable jacket defining a cable core, and a plurality of fiber bundles extending longitudinally through the core. Each fiber bundle comprises a plurality of optical fibers and a combination of color schemes, one color scheme that uniquely identifies each individual fiber by a particular base color, and a second color scheme that uniquely identifies each individual bundle based on a common color of one element in the bundle.

Abstract: A safety barrier for a vehicle mounted lift for wheelchairs is normally in an upright blocking position even when the lift platform is at a ground level. The barrier includes upper and lower panels which are hinged together and coupled with a pair of lever arms. A tubular slide coupled with each lever arm cooperates with a rigid link to bias the forward ends of the arms to elevated positions to maintain the barrier in an upright position. When the lever arms are manually lowered, the barrier upper and lower panels fold upon themselves to provide a ramp over which a wheelchair may be rolled for loading onto the lift platform. The arms are supported by the links in cantilevered positions and are connected to the panels for absorbing by deflection of the arms the energy from impacts from the wheelchair against the barrier.
