Abstract: A dock leveler scissors lift system mounted in a pit having back and side walls. The scissors lift mechanism comprises first and second scissors arms mounted on a base frame, one of the arms pinned to the base for pivotal movement and the other of the arms is free to move relative to said base. Hydraulics are employed to raise scissors lift. The scissors lift mechanism further comprises an upper frame having a generally horizontal deck portion. Retractable pins are used to couple said scissors lift mechanism to the pit in the fully raised position. The a dock leveler deck assembly is pivotally mounted to the generally horizontal deck portion of the scissor lift mechanism, and hydraulics coupled to the scissors lift mechanism raises the deck assembly. The scissors lift mechanism includes lip keepers that in one position retain the leveler lip in the pendent position and in a second position support the outboard end of the leveler deck.

Abstract: A seal for a vertically storing dock leveler employs a foam pad connected to the underside of the deck. As the leveler is lowered, the pad contacts the shelf on to which the leveler is mounted and deflects inward and compresses to seal the space between the underside of the leveler and the shelf. The pad is a tapered foam with a fabric covering.

Abstract: Operator intervention in parking a truck and positioning a dock leveler for performing a loading or unloading operation is simplified by a vehicle restraint actuator which is responsive to movement of the dock leveler or other vehicle loading mechanism to cause a vehicle restraint to engage an ICC bar of a vehicle. The vehicle restraint is held in place by a latch mechanism, which is released when the vehicle loading mechanism is moved to perform loading or unloading.

Abstract: A vehicle restraint mountable against a dock face uses a linearly extensible actuator member to move a flat plate restraining device into a vehicle release or restraint position. The plate carries a bracket having a cam profile which via a connection or latch arm converts the linear movement of the drive member into rotational movement of the restraining plate. In the vehicle restraining position all loading on the restraining device is transmitted to the frame without any force component on the actuator.

Abstract: Systems for identifying potentially erroneous and/or erased data are provided. Systems have a bit detector, an accumulator, and a data reconstruction processor. The bit detector assigns values to bits read in a data signal. The bit detector illustratively assigns multiple values to each of the bits. The accumulator accumulates a count of the multiple values assigned by the bit detector for each of the bits. The accumulator associates each bit with a particular value based at least in part on its accumulated count. The data reconstruction processor determines for each of the bits a confidence level of the particular value associated to it. The data reconstruction process sets flags for a portion of the bits. The flags identify the portion of the bits as possible erased or erroneous data. The flags are set based at least in part on the confidence levels of the portion of the bits.

Abstract: A method for detecting head-disc contact is disclosed. The method comprises locating a head including a head positioning microactuator and at least one of a read transducer and a write transducer adjacent to a disc such that the head is in communication with the disc, monitoring an output signal from the head positioning microactuator of the head, and evaluating the output signal to determine if the head contacts the disc.

Abstract: A system for enhancing the error correction capability of an error correction code (“ECC”) during error recovery operations accumulates, for respective bits, counts of the number of times the bits are detected as 1s in multiple re-reads of a data signal. The system then determines, based on the associated count, if a reconstructed bit should be considered a 1 or 0, or neither, that is, if the reconstructed bit should be considered erroneous, by comparing the count to a majority detection threshold and then to either an upper or a lower predetermined threshold that corresponds to the confidence with which the bit is reconstructed as a either a 1 or a 0. If the confidence is sufficiently low, that is, if the count falls below the upper threshold or above the lower threshold, the reconstructed bit is flagged as erroneous. After all of the bits are reconstructed, the system groups the bits into symbols to reproduce the ECC codeword, and sets erasure pointers that identify the locations of a predetermined number, s, of the symbols that are associated with the highest degree of uncertainty, that is, the largest numbers of flagged bits or, as appropriate, the largest numbers of flagged bits with the lowest confidence levels. The error correction operation then decodes the symbols in the identified locations as erasures. The system, using an (n, k) distance d Reed-Solomon ECC uses 2t=n−k redundancy symbols to correct the s erasures and up to 2 ⁢ t - s 2 errors.

Abstract: A dock leveler for bridging the gap between a loading dock and the bed of a vehicle parked at the loading dock. The dock leveler is configured for installation on the top of the dock and is designed to rotate from a vertically-stored raised position to at least one lowered, operative position. In some embodiments, the dock leveler can be lowered either for normal operation so that the deck assembly rests on the bed of the vehicle or it can be lowered to accommodate an end-loading condition.

Abstract: A system for restraining a vehicle, such as a truck having a pair of separated tires mounted on an axle, positioned at a loading dock. A member is movable from a stored position near or under the loading dock to an operative position under the vehicle and located between said separated tires. A pair of restraining elements are mounted on the movable member and are movable from a stored position between the tires to an outward extended position where each of the restraining elements engage a respective one of said pair tires. A mechanism, such as an hydraulic system, is mounted to said member at one end and to a fixed point at the other to move the member to a position under the vehicle. The pair of restraining elements is moved to the outward extended position by action of the moving mechanism for the member or by movement of a sensor that contacts a tire.
