Abstract:
A system for minimizing damage on collision to a vehicle having at least one self-propelled wheel is disclosed. The system comprises a motor in a wheel of said vehicle which drives the vehicle, means for measuring the speed of said wheel, means for measuring the torque of said motor, means for monitoring the ratio of the torque of the motor to the speed of the wheel, and means for stopping said motor when torque:speed ratio exceeds an acceptable value.
Abstract:
A method is disclosed for the induction of a suitable band gap and electron emissive properties into a substance, in which the substrate is provided with a surface structure corresponding to the interference of electron waves. Lithographic or similar techniques are used, either directly onto a metal mounted on the substrate, or onto a mold which then is used to impress the metal. In a preferred embodiment, a trench or series of nano-sized trenches are formed in the metal.
Abstract:
An aircraft ground control system that moves an aircraft on the ground between landing and take off without external mechanical assistance from airport tugs or tow vehicles or reliance on thrust produced by the aircraft's engines is provided. The aircraft ground control system interfaces only with an aircraft auxiliary power unit or other aircraft power supply, but otherwise operates independently of aircraft systems. A system integrator and controller links cockpit controls designed to actuate the transmission of power to system components and to activate system components only under predetermined conditions with selectively activatable drivers in driving connection with one or more aircraft wheels to move the aircraft on the ground at selected torques and speeds.

Abstract:
The present invention is directed to an apparatus for driving an aircraft having an undercarriage wheel, comprising aircraft drive means for driving an undercarriage wheel, and a clutch disposed between said driven means and said wheel, wherein said drive means and said clutch are directly connected to the undercarriage apparatus. Said apparatus may have gears disposed between said drive means clutch, or between said clutch and said wheel. In a most preferred arrangement, the apparatus of the invention fits inside the hub of said wheel. When the invention is applied to an aircraft undercarriage wheel, the clutch allows the wheel to be disengaged for takeoff and landing.
Abstract:
A drive system with harmonic drive designed to meet the high power and torque requirements required to drive an aircraft independently on the ground is provided. The drive system includes an electric motor driven by a harmonic drive assembly that may be configured to be integral with the motor. This drive system with harmonic drive can be effectively installed in an existing aircraft nose wheel or main wheel without changes to other components.
Abstract:
The present invention describes systems and methods for treating disorders and/or conditions associated with the dermal level of the skin. Such disorders include acne, hyperhidrosis, bromhidrosis, chromhidrosis, rosacea, hair loss, dermal infection, and/or actinic keratosis. Methods generally involve administering nanoemulsions (e.g., nanoparticle compositions) comprising at least one therapeutic agent, such as botulinum toxin. In some embodiments, nanoemulsions are prepared, e.g., by high pressure microfluidization, and comprise a particle size distribution exclusively between 10 nm and 300 nm.
Abstract:
The present invention provides nanoparticle compositions including one or more peptides. The present invention achieves transdermal delivery of such peptides without the need for peptide modification, or for use of chemical or mechanical abrasion or disruption of skin.
Abstract:
The present invention is a rotating induction motor that is capable of providing higher peak torque than a conventional design, which achieves the shortcomings of the prior art by in regard to iron saturation by a slot-less design; removing the iron slot provides more space for the conductor. The motor comprises a stator and a concentric rotor, separated from the stator by an air gap. The rotor has rotor bars and rotor windings. The stator is slot-less and comprises surface mounted conductors separated from each other by suitable insulation. An advantage of this design is that the motor does not exhibit typical behavior at high currents; there is no saturation effect.
Abstract:
The present invention is a compound planetary gear system which has a moveable sun gear and a lockable sun gear to change the gear ratio between a high gear ratio and a pseudo 1:1 slipping ratio. The system makes use of a ratchet and pawl mechanism to provide a safety backup for when the lockable sun gear is locked. The invention may be used to move the aircraft from a stationary position, for taxiing, and for pre-rotating the wheels prior to landing.
