Abstract
A system for assisting in the use by an operator of the operating element of a tool at desired locations at a worksite, includes a stationary control and a position sensor secured to the tool. The stationary control is located at the worksite, and has data stored therein specifying one or more desired locations for operation of the operating element of the tool at the worksite. A position sensor is mounted on the tool. The position sensor determines the position of the operating element of the tool. The position sensor includes a communication device for communicating with said stationary control, a sensor for determining its relative position with respect to said stationary control, and a display for providing indications to the user of the tool of the desired location for the operating element of the tool and of the actual location of the operating element of the tool.

6. A system for determining dimensional coordinates of an operating element of a tool in a work space and indicating to a user of said tool that said operating element is properly positioned for operation, comprising:
-
a tool having an operating element, a pair of ranging radios mounted on said tool, a first ranging radio spaced from said operating element by a first distance, and a second ranging radio spaced from said first ranging radio by a second distance, a stationary control for measuring the positions of said pair of ranging radios in said work space, said stationary control including a plurality of fixed position ranging radios located at known positions in said work space and a measurement circuit, responsive to said pair of ranging radios, for determining the position of said pair of ranging radios with respect to said plurality of fixed position ranging radios, and for determining the position of said operating element of said tool with respect to said plurality of fixed position ranging radios, and a display, mounted on said tool, for indicating that said operating element is properly positioned at a desired location for operation of said tool and for indicating an actual location of said operating element of said tool. - View Dependent Claims (7, 8, 9, 10)
