Abstract: An immobilizer device is provided for preventing the travel of a wheel, particularly the wheel of a vehicle. The immobilizer device utilizes an elongated pin to pass through a portion or aperture of the wheel, and the immobilizer device prevents travel of the wheel by acting as a chock. Some embodiments of the immobilizer device comprise an indexing feature to guide the elongated pin into an aperture and a receiver tube to guide the elongated pin into another aperture. Then the elongated pin may be placed in a locked position to secure the immobilizer device to the wheel.

Abstract: A method of controlling a power converter is used to interface to a power grid or supply network operating at a frequency (Fnet) that is nominally fixed (say at 50 Hz, for example) but which can be varied as a way of controlling power imbalanced within the network as a whole. The power converter can include a network bridge that operates in accordance with the pulse width modulation (PWM) strategy having a switching frequency (Fpwm), a nominal switching frequency (Fpwm_nom) and a number of pulses per period (Pulse_Number).

Abstract: A two-piece vehicle immobilizing device adapted for removable interconnection to a vehicle wheel assembly. The vehicle immobilizing device utilizes an outer arm, an inner arm with inner and outer indexing stops, an engagement dome, and a securing mechanism that provides engagement to the vehicle wheel assembly to prevent unauthorized removal.

Abstract: The present invention is adapted to immobilize a vehicle by utilizing a pair of selectively interconnected chocks that are placed fore and aft of a tire. The chocks are preferably used to secure aircraft and/or aircraft ground support equipment from unauthorized motion in airport parking areas.

Abstract: The present invention relates generally to manifolds adapted to receive a fluid stream from one location and distribute it to a plurality of different locations. More specifically, one embodiment of the present invention includes an in-line, generally cylindrical, manifold adapted to receive high volumes of fluid and distribute it to a plurality of discharge nozzles. It is envisioned that these smaller volume discharge nozzles would be interconnected to hoses, wherein the fluid is transported to various locations for a preferred use. For example, in one embodiment of the present invention, the manifold would be used to transport treated water to various decontamination units to treat victims of chemical, biological, or nuclear attacks.

Abstract: An automated fee collection and ticket dispensing machine is disclosed that is capable of operating under a variety of operating modes. The machine permits users to purchase a variety of passes. The disclosed machine includes printers to produce receipts or passes for services or activities. Payment may be made using credit cards, debit cards or cash. The device is provided with networking means, to allow central control and monitoring of the device. Power for the machine may be provided by hard-wiring the device to conventional AC power lines, by solar panels, by batteries, or a combination of any of these. The user interface includes a video output screen with “touch screen” capability to receive user input, audio output means, and a proximity sensor to activate the machine when a user approaches. Additionally, security means are provided to deter potential thieves or vandals.
