Abstract: SAFELANDER provides a method of safely operating aircraft, equipped with a Flight Control Unit, Instrument Landing System, and Autopilot, remotely on the ground and/or in congested airspace. The remote pilot, who can concurrently control a plurality of operational aircraft, communicates with Air Traffic Control and operates in a secure, synthetic vision, high fidelity, virtual reality cockpit simulator located in a ground-based facility. The patent saves cost and weight by providing a method for safely piloting traditionally dual piloted operational aircraft with just a single onboard pilot. The invention protects aircraft, edifices and the population from pilot error and/or terrorists. Decreases cost of air travel. Quickly, safely and effectively responds to emergencies. Increases flight safety and security. SAFELANDER ciphers and utilizes the two-way RF ground to aircraft and aircraft to ground telecommunication links and critical aircraft flight control data of U.S. Pat. No.

Abstract: A traction control apparatus for vehicles according to the present invention has a slip state detector for detecting a slip state of a wheel, a parameter determining device for determining a control parameter for generating braking force according to the slip state detected, a control permitting device for permitting traction control, a parameter changer for changing the control parameter so as to decrease the braking force when the control parameter is one to generate the braking force at the wheel over permissible braking force at the start of control, and a traction control for executing the traction control, based on the control parameter. Thus the apparatus can restrain uncomfortableness during the traction control and can prevent large input from entering the power train.

Abstract: A ballet ski is provided for achieving enhanced stability when a skier is stationary or moving slowly. The bottom surface of the ski has a planar elliptical portion centrally under the foot of the skier. Remaining portions of the bottom surface are convex from front to rear and convex from side to side. Thus, a skier can easily roll from the planar ellipse and into the curved portion to carry out selected ballet maneuvers. Preferably, the ski is formed from separate top and bottom components configured to form air pockets that reduce the weight of the ski. The ski may also include chamfers near the rear binding to enable a brake to rotate into the snow. Additionally, hook receiving apertures may be formed through the rear end of the ski. A pair of the skis may then be used with straps having hooks engageable in the apertures for conveniently suspending the skis in a carrying position.
