摘要: A method and apparatus for determining a trajectory for a vehicle can include: identifying a starting position (p0) and desired terminal position (P) for the vehicle; linearly approximating dynamics of the vehicle; and using the starting position (p0), terminal position (P), and linear approximation, determining the trajectory; wherein the linear approximation can be constrained by a requirement (e.g., specification) that the vehicle may not travel in a region; a center point of the region is at a distance from a predetermined point on the vehicle substantially equal to a minimum turn radius of the vehicle, in a direction substantially perpendicular to a velocity of the vehicle; and a distance from the center point of the region to a point on a perimeter of the region is greater than or substantially equal to the minimum turn radius of the vehicle.

摘要: An apparatus and a method are disclosed for tracking a plurality of targets (e.g. land-based vehicles). The method can include: for a first time-step, estimating a state of each respective target; at a second time-step, measuring values for a state of each target; for the second time-step, estimating a state of each target using the estimated target states for the first time-step; updating the estimated target states for the second time-step by performing a Joint Probabilistic Data Association process using the measured values; and performing an identity management process to estimate a probability that a particular state measurement corresponds to a particular.

摘要: Shadow sensing apparatus for measuring the cross-section and/or position of a tool such as a welding tool at its intersection with a sensor plane, the apparatus having three sensor channels, each comprising a linear array of discrete light sources and a linear light sensor opposite the light sources to receive light emitted therefrom. Each of the channels intersects each other to define a common sensor plane. The light sources are actuatable individually to direct light towards the tool and the respective sensor is arranged to sense the shadow cast thereon by the tool. The cross-section and/or position of the tool or other subject can be determined from up to n×C shadow images, where n is the number of light sources in each of the arrays and C is the number of channels.

摘要: A keg conveying trolley has a pair of wheels, a central post and a slide which carries a hook for grasping the keg rim. The slide is lockable at different keg heights. A foot plate assists in tipping the trolley to an inclined position for wheeling the keg from one place to another. The keg stacking version has a winch worked by hand or a cordless drill. The keg is supported by a rise and fall carriage. The carriage can be modified to be multitask. Variants can lift gas bottles on their side, truck tyres for placing on wheel studs and odd shaped loads.

摘要: A filler cap assembly includes a sleeve welded to a tank wall, and a non-indexing filler cap. The cap is formed with top and bottom members, each member having an outwardly bevelled surface opposing a corresponding surface on the other member. An elastic O-ring is positioned between the two surfaces. The top member and base member are held together by an axially extending shaft, with a spring biasing apart the two members. The shaft is connected in a hinged manner to a cam lever. Activation of the cam lever brings the two opposing surfaces together, forcing the O-ring outward to form a seal with the sleeve. The filler cap and the sleeve's inner wall are provided with additional features which maintain the filler cap in the sleeve.

The vehicle may have a curvature limit.
