Abstract: A method and system for determining the position of a vehicle comprises a transmitter or transceiver for transmitting a transmission signal from a vehicle to beacons associated with the work area. Each beacon is associated with a corresponding transceiver or receiver for receiving the transmission signal. A data processor at a beacon, the vehicle or both determines an elapsed time including at least one of a first propagation duration and a second propagation duration. The first propagation duration refers to a propagation time of the transmission signal from the vehicle to the particular beacon; the second propagation duration refers to a propagation time of a return signal from the particular beacon to the vehicle. A compensator compensates for one or more of the following associated with at least one of the transmitter and the particular beacon: bias delay, noise, and measurement error. A data processor processes the elapsed times (for paths between vehicles and beacons) into corresponding position curves or temporal curves to estimate a position of a vehicle at a confluence or intersection of the position curves or temporal curves.

Abstract: A first location determining receiver determines a first location estimate of a vehicle. The first location determining receiver is associated with satellite beacons. A second location determining receiver determines a second location estimate of a vehicle. The second location determining receiver is exclusively associated with terrestrial beacons. A selector selects the first location estimate of the vehicle as a preferential location in accordance with an initialization scheme for the vehicle in a work area. A filtering module applies a first weight to a first location and a second weight to the second location to derive a weighted estimate as the preferential location upon satisfactory completion of the initialization scheme.

Abstract: A frame of a mower supports wheel assemblies, a propulsion unit, and a mowing deck. Each wheel assembly is associated with a corresponding wheel, a corresponding electrical steering motor, and a corresponding electrical drive motor. A controller controls a direction of orientation of the corresponding wheel via the corresponding electrical steering motor. Further, the controller controls the application of electrical energy to the corresponding drive motor consistent with maneuverable movement of the mower. The propulsion unit is capable of rotating at least one cutting blade. A mowing deck houses the at least one cutting blade. The mowing deck has indentations to provide a spatial zone for the plurality of wheel assemblies.

Abstract: A method for operating a mower comprises defining a reference axis of rotation at a desired point along a path segment of the mower. A controller orients wheels of the mower generally tangentially to a circular region about the reference axis. A drive motor applies rotational mechanical energy to one or more of the wheels to rotate the mower by a desired angular amount about the reference axis.

Abstract: A transmitter at a lead vehicle transmits a first transmission signal toward a first beacon and a second beacon associated with a following vehicle. A data processor or estimator determines a first propagation time associated with the first transmission and the first beacon and a second propagation time associated with the first transmission and the second beacon. A vehicle controller controls a heading of the following vehicle to maintain a first distance substantially equal to a second distance (i.e., first propagation time substantially equal to a second propagation time) or a first distance that deviates from the second distance by a predetermined maximum amount.

Abstract: A time estimator determines a first aggregate elapsed time between the transmission of the first transmission signal to a first beacon and receipt of a return signal, a second aggregate elapsed time between the transmission of the first transmission signal to a second beacon and receipt of a return signal, and a third aggregate elapsed time between the transmission of the first transmission signal to a third beacon and receipt of a return signal. A bias compensator compensates for bias delay associated with at least one of the first transmitter, the first beacon, the second beacon and the third beacon. A converter converts the first aggregate elapsed time, the second aggregate elapsed time, and the third aggregate elapsed time into position curves. A data processor estimates a position of the vehicle at a confluence or intersection of the position curves.

Abstract: An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a healing manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material enclosed by sheets of elastomeric material punctuated by a number of appropriately placed holes. Multiple layers of porous foam may also be used. A suction tube connector is provided on an upper surface of a layer of foam for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope and through the foam.
