According to the invention, a path (109) is determined by the following iterative method: an arc-shaped path (109) about the reference position (106) at a defined distance therefrom is determined step by step and the absence of obstacles a(103) long the arc-shaped path (109) is verified. As long as no obstacles (103) are detected the arc-shaped path (109) is extended. If an obstacle is detected th...

In one embodiment of the present invention, an apparatus and method for determining a path (22) or series of paths at a work site (20) for a mobile machine (28) capable of operating autonomously or semi-autonomously is provided. The present invention determines a series of rows that are substantially parallel to the machine's (28) heading. The width of the rows is based on the width of the path (2...

A polyester support in which a difference between orientation angles in both the side edges and that in the center thereof is from 0 DEG to 40 DEG , whereby a photographic film having excellent flatness after heat treatment is provided.

A biaxially oriented polyester film formed from an aromatic polyester composition containing: (A) 100 parts by weight of an aromatic polyester, and (B) 0.005 to 5 parts by weight of calcium carbonate particles defined by: (a) a length/width ratio (2a/2b) in the range of from 1.25 to 3, (b) an average particle diameter (D), as a diameter of a circle converted from an area, in the range of f...

Two unique quick connect fluid coupling embodiments have a tube inner end (36) which does not contact a seal (42, 44) if the tube (22) is not fully connected. Preferably, a retainer retains the tube (22) within the bore of a housing (24). The retainer (30) is of the avalanche type such that a high force is required to insert the tube (22), and once this high force is overcome the momentum of the t...

Arithmetic operations are performed on composite operands that include plural component data items. The operations obtain valid results even though the operations would ordinarily produce inter-component signals, such as carry or borrow signals or a shifted bit, causing invalid results. For example, the component data items can be pixel values or other data relating to pixels in an image. Instruct...
