  • Publication number: 20120055180
    Abstract: An isolated cold plate refrigeration system provides a cargo compartment isolated from a cold plate compartment. A user defines the target temperature of the cargo compartment. When the temperature of the cargo compartment rises above the target temperature and cool air is required to reduce the temperature of the cargo compartment, a cold plate fan is activated to move air from the cold plate compartment to the cargo compartment and from the cargo compartment to the cold plate compartment.

  • Patent number: 7651404
    Abstract: A full-sized outdoor golf course is described with any number of holes, usually 18 or 36 holes. Each hole is made up of a tee, a fairway, and a green. The holes are laid out in a pattern that makes it practical for each group of players on the golf course to play the holes in random order. This is accomplished by organizing the holes in a pattern that greatly increases the number of tees that are available to pick from after leaving any green on the course. All tees and greens, and only tees and greens, but no fairways, are located along special cart paths (44, 46, 48, 49, 50), that run roughly perpendicular to the normal cart paths that usually run along each fairway, so that when finishing play on any green, several tees are reachable by golf cart in a relatively short predetermined time, preferably 1½ minutes or less, using the special cart paths (44, 46, 48, 49, 50).

  • Publication number: 20070209378
    Abstract: A vehicle integrated power and control strategy for cold plate refrigeration system for a mobile vehicle. The system is essentially a hybrid refrigeration system that includes a conventional cold plate cooling system as well as an onboard refrigeration system that will charge the cold plates when the plates lose some of their chilling capacity. The system requires minimum generator capacity because the onboard integrated system has a low power draw gradual starting compressor. When the vehicle is in use the compressor will only energize if the residual cooling effect diminishes from the plates, hence the hybrid effect. After the vehicle is returned to its home base, there is capacity to engage a shore power hookup and run the compressor from shore power.

  • Publication number: 20070192010
    Abstract: A position sensor (20) associated with a brake pedal (22) discloses deceleration request data corresponding to a vehicle deceleration request by the driver. A processor (12) executes an algorithm that compares sensor deceleration request data with data representing deceleration that is potentially obtainable by operating one or more mechanisms in the powertrain such as an exhaust brake or an engine brake. Operation of the one or more mechanisms is requested when the comparison discloses that operation of such mechanisms can satisfy the request, thereby precluding the need to apply foundation brakes. Pedal depression beyond a range within which the mechanisms are potentially capable by themselves of satisfying the request, causes foundation brake application so that a fault that does not result in braking by the mechanisms will cause the foundation brakes to be applied when the driver, sensing lack of braking, depresses the pedal further.

  • Publication number: 20060137924
    Abstract: A vehicle energy management system relying on the principle of reallocation of existing resources provided by the vehicle manufacture. Engine belt or engine direct driven components are replaced with electrical motors. Since replacement of the main fan unit would involve a prohibitively large fan due to starting currents, the larger component that would have multiple cooling purposes is replaced with smaller single function electrical components. The larger multipurpose heat exchangers such as the vehicle radiator are replaced with smaller single function heat exchangers associated with the smaller electric fans. The energy management system may involve a main vehicle engine crankshaft mounted generator. This simple generator creates high voltage DC electricity that may be converted to household level AC for the operation of customer application equipment.

  • Publication number: 20060131950
    Abstract: The brake lining and wear estimation system operates using extant vehicle sensors such as those used to implement height and stability control systems or anti-lock brake systems. This minimizes, or eliminates, the need to modify the brake units themselves. Compressed air systems used on heavy duty vehicles to support the operation of various systems, including air brakes, provide pressure monitoring features in various pneumatic circuits, which can be monitored to estimate brake lining application pressure or vehicle loading. Vehicle speed and brake actuation periods are derived from other commonly employed sensors. Data collected from the sensors is supplied to a central, programmable computer over a data bus to generate the heat and wear estimates.

  • Publication number: 20050166592
    Abstract: A motor vehicle kinetic energy recovery system uses one or more cylinders of an internal combustion engine as the first or primary stage in a multi-stage high pressure air compression system, a compressed air storage system, compressed air operated drive train boosters and vehicle management electronics to provide cooperation between the air compression, storage and booster systems. The multi-stage, high pressure air compressor system is operable through engine compression braking allowing kinetic energy of a vehicle to be recaptured during retardation of vehicle speed.
