Abstract: A vehicle for removing an accumulation of particles comprises a vehicle body, a system configured to remove the particles in bulk, and an arm coupled to and extending from the vehicle body. The arm comprises a first sweeping element and a second sweeping element. Each sweeping element includes a shaft member rotatable about a longitudinal axis, and a set of bristles projecting away from the axis along the shaft member. The first and second longitudinal axes are a distance apart, and the sweeping elements define a concerted sweeping area. The arm may be movably coupled to the vehicle body and may be configured to move the sweeping element around the vehicle body by rotating the arm about a horizontal axis. When a sweeping element rotates in proximity to the ground, the longitudinal axis is substantially vertical. The vehicle may further include a computer system for tracking the location of an object.

Abstract: This invention relates to a device mountable within a vehicle and connectable to a power source to monitor and warn drivers of the lateral g-forces being experienced by the vehicle during use. The device comprises an accelerometer means comprising an accelerometer chip capable of measuring the lateral g-forces between 0 and 1 g-force units experienced by a vehicle upon mounting the device in the vehicle by providing a signal output indicative of the lateral g-force experienced; adjustment means adjustable by the operator of the vehicle for varying the signal output from the accelerometer means; measuring means for measuring the signal output emitted from the adjustment means; and indicator means for indicating to the driver when the mounted vehicle experiences lateral g-forces of a magnitude programmed by the adjustment means.
