Abstract: An article of clothing is disclosed for use as an outerwear garment (100). The garment comprises a planar integral portion (101) having a elliptical configuration. Invertible sleeves (113, 114) are attached at armholes (107, 106) in the integral portion at a position allowing for use as shawl-length outerwear and additionally for inverted use as floor-length outerwear.

Abstract: A flight performance data system comprises a control and display unit operably connected to a computer. The computer has input means responsive to real air mass parameters and real aircraft dynamic measurements. The computer is programmed to respond to the incoming signals and automatically generate various output signals representing flight profile data. A mode selector is operably connected to the computer to direct the computer in different modes to determine the different flight profile data for the climb, cruise, descent and other modes of the aircraft. For various modes, a different flight schedule can be determined corresponding to the most fuel efficient flight, a long-range cruise flight, or the most economical flight. In addition, the computer produces output signals corresponding to the maximum rate of climb and the maximum rate of descent in the climb and descent modes, respectively. A display screen selectively displays the desired flight profile data.

Abstract: An automatically guided vehicle wherein a guide line is positioned in a predetermined path on the floor and the vehicle has a sensing head positioned over the guide line to detect the position of the guide line with respect to the vehicle and to generate an error signal representative of the vehicle position with respect to the guide line. A control circuit is also provided on the vehicle to steer the vehicle responsive to the error signal generated by the sensing head. The sensing head includes a scanning head to scan across the guide line and to generate an output signal representative of the detected light values at discreet positions of the scan. The control circuit is adapted to steer the vehicle along the right edge, left edge or center of the guide line and is responsive to control codes positioned on the floor adjacent the guide line.
