20130255411 | TENSIONING ASSEMBLY FOR CABLE DRIVE - A window regulator assembly having cables for driving one or more lifter plates along rails includes connectors for connecting the ends of cables together. The connectors are connectable together in a ‘use’ position and can be held in a lifter plate in the use position. By having the connectors connect to each other they withstand the tension in the cables when the window regulator assembly is at rest and the lifter plate is only required to withstand the differential tension between first and second cable segments during movement of the lifter plate. This allows the lifter plate to be formed from a relatively lower strength and less expensive material since it is subject to relatively lower stresses than prior art lifter plates. | 10-03-2013 |

20130333497 | TRANSMISSION DEVICE - A transmission device includes a bracket, a belt, a driven module, and a limiting member. The bracket includes a mounting plate and a limiting piece extending from the mounting plate. The idle module is slidably mounted to the mounting plate. The belt is engaged with the idle module and preventing the idle module from sliding along a first direction relative to the mounting plate. The limiting member is located in a side of the idle module and rotatably mounted to the limiting piece. The limiting member abuts the idle module along the first direction, to prevent the idle module from sliding along a second direction, which is opposite to the first direction. | 12-19-2013 |
20140190289 | MOTORIZED DRIVE SYSTEM AND METHOD FOR ARTICULATING A JOINT - A motorized drive system and method for articulating an articulated joint having a motor and an elastic cable.
