Abstract: A vehicle anti-theft entry system includes a keypad, a first and second indicator lights, and a theft deterrent module disposed in the vehicle. The theft deterrent module asserts the first indicator light and receives a PIN from the keypad. An access control module comparing the PIN to a list of codes. If the PIN matches a restricted code the access control module sends a restricted access code to the theft deterrent module, if the PIN matches an unrestricted code of the list of codes the access control module sends an unrestricted access code to the theft deterrent module, and if the PIN matches none of the list of codes the access control module sends a deny access code to the theft deterrent module. The theft deterrent module receives the access code and asserts the first indicator light and outputs deny data to control substantially a function of the vehicle if the access code is the deny access code.

Abstract: A self-canceling turn signal includes an inner wheel rotating at an inner velocity and an outer wheel rotating at an outer velocity. An inner rotational velocity of the inner wheel and an outer rotational velocity of the outer wheel may be measured and compared, and a turn signal may be responsive to a differential signal substantially proportional to the difference between the inner and the outer rotational velocities. The turn signal may signal a turn while the differential signal is greater than a predetermined differential signal.

Abstract: A coupling and load support for suspending or hanging a load from the head of a coal mine roof bolt wherein the coupling takes the form of a thin-walled, open-ended, substantially square-shaped housing or receptacle which is structured so that the upper portion thereof can be rigidly attached to the head of the roof bolt by one or more bolts threadedly carried in the housing and is also structured so that the lower portion thereof can carry or be connected to a load support. A load of various types can be carried by the load support and the load can thereby be suspended from the head of the roof bolt.

Abstract: This invention is directed to a coupling or a connector for securing a load-bearing support to a head of a bolt, particularly in a mining operation in which roof bolts have been used for shoring the roof of the mine. The coupling or connector is secured to a bolt head by which machinery may be lifted and or moved. A bolt may be secured in a wall to which the coupling or connector could be secured to the head for moving machinery from one place to another.
