| 20090211220 | LINK FOR A LINEAR ACTUATOR - A link for a chain, which is used in a linear actuator, comprises a base member and a plate pivotably mounted on the base member. An arm extends from the plate. A first connecting means is disposed on a distal end of the arm to connect the link with a first adjacent link. The plate has a protrusion for releasably engaging a second adjacent link. A second connecting means is disposed on the base member to connect the link with the second adjacent link. | 08-27-2009 |

| 20080199295 | SINGLE CHAIN LINEAR ACTUATOR - A linear actuator comprises a chain having adjacent first and second links. A pivotal connection pivotally connects the first link to the second link. The first link is pivotable about a pivot axis which is non-perpendicular to a longitudinal axis of the first link. A locking mechanism releasably locks the first link and the second link to prevent the first link from pivoting about the pivot axis. A releasing mechanism releases the locking mechanism to allow the first link to pivot about the pivot axis. A drive mechanism moves the chain between an extended position and a retracted position. At least a portion of the chain is helically wound when the chain is in the retracted position. | 08-21-2008 |
| 20080200294 | DOUBLE CHAIN LINEAR ACTUATOR - A linear actuator comprises a pair of chains. Each chain has a first link and a second link. The second link of each chain is adjacent to the first link of the chain. A pivotal connection pivotally connects the first and second links. The first link is pivotable about a pivot axis which is non-perpendicular to a longitudinal axis of the first link. A chain connecting member connects the chains at distal ends thereof. A drive mechanism moves the chains between an extended position and a retracted position. At least a portion of each chain is helically wound when the chains are in the retracted position. | 08-21-2008 |

| 20090032328 | TORQUE SENSOR TYPE POWER STEERING SYSTEM WITH SOLID STEERING SHAFT AND VEHICLE THEREWITH - A steering apparatus includes a rotatable steering shaft having an exterior, an input end for connecting a steering member and an output end for connecting to at least one steerable wheel of a vehicle. An electric motor is operatively connected to the steering shaft for rotating the steering shaft. The shaft is magnetized and serves as a torque sensor transducer. At least one magnetic field sensor is adjacent to the exterior of the steering shaft. The steering shaft and the at least one magnetic field sensor form a torque sensor for sensing torque applied to the steering shaft by the manually operable steering member and provide a signal to operate the electric motor to assist steering of the steering shaft by the manually operable steering member. | 02-05-2009 |
