20150270738 | MAINTAINING CONTINUOUS POWER CHARGE IN AN INDUCTIVE-COUPLING SYSTEM - Maintaining continuous wireless charging of a device includes various elements. Events that may disrupt wireless charging are detected and the disruption circumvented by adjusting functions of an inductive coil. A frequency and power-shifting methodology is employed to achieve the continuous wireless charging. The invention may be implemented into various devices and environments, including vehicle consoles. | 09-24-2015 |
20140265512 | HEIGHT ADJUSTMENT MECHANISM SUITABLE FOR A FOOTRING - A mechanism for vertically adjusting a component on a shaft has a collet sleeve riding on the shaft. A spiral track of the component's hub receives a radially outwardly projecting pin on the collet sleeve. The outer surface of the collet sleeve and the inner surface of the hub are tapered so that the hub can rotated one direction to advance the hub on the collet sleeve and compress the collet sleeve onto the shaft to frictionally lock the collet sleeve to the shaft. Because the hub is joined to the collet sleeve by the pin, this also locks the vertical position of the component. Conversely, the hub can be oppositely rotated to release the compression of the collet sleeve so that the collet sleeve, and therefore the vertical component, is slidable on the shaft. | 09-18-2014 |
20140191553 | CABLE SYNCHRONIZER SYSTEM - An actuation system for concurrently actuating a first mechanism and a second mechanism from a first state to a second state includes an actuator and a sliding member operatively engaged with the actuator and movable from a first position to a second position in response to actuation of the actuator. A connecting member has a relaxed state and a taut state. The connecting member includes a first end coupled to the first mechanism, a second end coupled to the second mechanism, and a medial portion cooperative with the sliding member. Movement of the sliding member from the first position to the second position changes the connecting member from the relaxed state to the taut state, whereby the tension is increased in the connecting member. | 07-10-2014 |
20140070584 | LUMBAR SUPPORT SYSTEM - A lumbar support system for a seat backrest having a fixed frame includes a lumbar support coupled to the fixed frame that is movable from a first position to a second position and a motor for moving the lumbar support. A threaded member is operatively associated with the motor such that the motor rotates the threaded member about an axis. A traveling member is operatively associated with the threaded member such that rotation of the threaded member translates the traveling member along the threaded member. The system further includes a flexible cable having a first end and a second end. The first end is coupled to the traveling member for movement therewith and the second end is coupled to the fixed frame such that translation of the traveling member in response to rotation of the threaded member moves the lumbar support element from the first position to the second position. | 03-13-2014 |
20090267395 | PIVOT ASSEMBLY - A pivot assembly has a pivot support member with a keyway. The keyway has two oppositely directed longer keyway wings extending from a middle section and the middle section has two oppositely directed shorter keyway wings extending in a direction transverse to that of the longer keyway wings. The shorter keyway wings have convexly radiused ends. The pivot assembly also has a pivot with an attachment portion and a key projecting rearwardly from the attachment portion. The key has a rearward section with oppositely directed longer key wings which are longer than the shorter keyway wings but sufficiently short to allow the longer key wings to pass through the keyway. The key also has a middle section between the rearward section and the attachment portion. The middle section has oppositely directed shorter key wings with convexly radiused ends. The shorter key wings extend in a direction aligned with that of the longer key wings. The shorter key wings have a length substantially matching that of a length of the shorter keyway wings. The radiused end of each shorter key wing has a radius substantially matching a radius of a radiused end of each of the shorter keyway wings such that the shorter key wings fit with a close tolerance between ends of the keyway shorter wings. | 10-29-2009 |
20090235775 | TORQUE LIMITING HANDLE ASSEMBLY - One member of a two member torque limiting handle assembly has resiliently depending legs extending about its rotational axis. The second member has features arranged such that on rotation of said first member, the features contact the legs so that when a reaction torque of the second member is less than a threshold value, the second member rotates with the first member and when a reaction torque of the second member is greater than the threshold value, the legs resiliently deflect so that the features simply pass across said legs and the second member does not rotate with the first member. | 09-24-2009 |
