Claim:
A dock leveler being movable in relation to a dock platform and a vehicle bed, the dock leveler comprising: a deck having a front edge and a back edge, wherein the front edge relative to the dock platform is movable between an uppermost deck position, a lowermost deck position, and a plurality of intermediate deck positions therebetween; a lip coupled to the deck; the lip includes a tip and a rear edge; the rear edge is in proximity with the deck; the lip is movable between an extended lip position, a retracted lip position, and a plurality of intermediate lip positions therebetween, wherein the tip is closer to the back edge of the deck when the lip is in the retracted lip position than when the lip is in the extended lip position; a logic circuit; and a position sensor operatively coupled to at least one of the deck and the lip, the position sensor providing a signal that varies as a function of at least one of a position of the deck and a position of the lip, such that: a) the signal is to enable the logic circuit to distinguish among the plurality of intermediate deck positions when the signal varies as a function of the position of the deck, and b) the signal is to enable the logic circuit to distinguish among the plurality of intermediate lip positions when the signal varies as a function of the position of the lip.
