Abstract: An apparatus for controlling vehicle movement comprises processing means configured to receive first signals from a receiving means arranged to receive transmitted signals from a remote control device indicating a requested motion of the vehicle. From the first signals or an additional signal received from a sensing means, one or more distance values indicative of a distance from a point on the vehicle to an object is determined, and a maximum speed value for the vehicle is determine in dependence on the one or more distance values. The processing means provides an output signal for controlling speed of the vehicle based on the requested motion. The output signal is arranged to control the speed of the vehicle to be less than or equal to the maximum speed value.

Abstract: A method for transporting a recreational vehicle, such as a motorcycle or snowmobile in the cargo box of a pickup truck in a fashion that enables the tail gate of the pickup truck to remain closed. A first step involves providing a pickup truck having a cargo box with an open end closed by a tail gate. A second step involves placing the recreational vehicle in the cargo box of the pickup truck with a rear portion of the recreational vehicle protruding past the open end. A third step involves positioning a support into the cargo box adjacent to the open end. A fourth step involves lifting the rear portion of the recreational vehicle onto the support until the rear portion is elevated sufficiently to provide clearance to enable the open end to be closed by the tail gate.

Abstract: Apparatus for taking a multiple of samples of groundwater or pressure measurements from a well simultaneously. The apparatus comprises a series of chambers arranged in an axial array, each of which is dimensioned to fit into a perforated well casing and leave a small gap between the well casing and the exterior of the chamber. Seals at each end of the container define the limits to the axial portion of the well to be sampled. A submersible pump in each chamber pumps the groundwater that passes through the well casing perforations into the gap from the gap to the surface for analysis. The power lines and hoses for the chambers farther down the array pass through each chamber above them in the array. The seals are solid, water-proof, non-reactive, resilient disks supported to engage the inside surface of the well casing. Because of the modular design, the apparatus provides flexibility for use in a variety of well configurations.
