Abstract: An operator, using the Laser Guide operating procedure, can accurately position the Guide vehicles to the hitch point of a vehicle, trailer or 5th wheel. The operator may choose to use the dual lasers (prior art), the Guide and lasers, or only the Guide. The Guide mechanism consists of a retractable tape to connect the vehicles, a dual light signaling device, a rolling stop switch, and a backup camera display or a panel. A one time initial setup with vehicles hitched, requires several minutes. The hitching procedure is user friendly. The accuracy of the Guide can be demonstrated by a working model.
Abstract: A gauge for cartridges is disclosed. The gauge includes a gauge body defining an opening, a window, and receiving space. The opening and the receiving space share an axis and are in direct communication with each other. The window is in direct communication with the receiving space. The opening and the window are separated by a body portion of the gauge. Each gauge has a receiving space that is sized and shaped to correspond to a predetermined cartridge.
Abstract: A surface property measuring device includes a measuring arm that is supported so as to be capable of circular arced movement, a stylus that is provided to a distal end of the measuring arm, a position change detector that detects a change in position of the measuring arm, and a measurement force applier (voice coil motor) that biases the measuring arm in a circular arced movement direction and applies a measurement force. A control device includes a central controller that outputs a measurement force instruction that issues an instruction for an orientation and size of the measurement force, and a measurement force controller that controls the orientation and size of the measurement force produced by the measurement force applier.
