A control bar extends upwardly from the front end of the board and has two rods extending therefrom which clamp a protrusion extending from the mediated portion of the transverse plate so that when pushing the control bar, the transverse plate is shifted due to the connection between the two rods and the transverse plate so as to control the directions the front wheels turn.

Abstract: A one-piece pintle hitch is disclosed. The one-piece hitch utilizes an integral drawbar that may be engaged with a conventional receiver assembly such as installed along the underside of a vehicle. The one-piece pintle hitch avoids the use of prior art mounting plates that bolt to one another. Accordingly, the problems associated with threaded fasteners such as loosening, fracturing, and corrosion are eliminated. In addition, the one-piece pintle hitch utilizes a unique configuration along its bar portion that results in a significant reduction in weight and materials.

Pre-calibbrated devices are selected from the database and the focussed image is digitized and stored so as to produce a digitized image which is analyzed so as to determine an electro-optical performance representative of the performance of the electro-optical system which is equal to the product of component electro-optical performances of each of the electro-optical test devices and each of the additional pre-calibrated devices.

Abstract: An artificial visual apparatus and method for image recognition having a simple adaptive scaling mechanism enables the definition of scale invariant visual icons in a processing area corresponding to the anterior inferotemporal cortex (AIT) in a one-step, value-based decision making process. Icon related activity states resulting from sensory filtering to a fourth stage KL filter corresponding to the V4 area are recognized independent of the scale and position of the item to be recognized within the maximum visual field. The AIT processing area controls the window of attention in the V4 area and confines further processing onto this selected spotlight. The invention presents a biologically plausible method for scale invariant mapping from the V4 stage filter to the AIT processor.
