20130242256 | METHOD AND APPARATUS FOR DETECTING ACCOMMODATION - A sensor system includes at least two sensors for distinguishing accommodative stimuli from changes in ambient lights levels and task-induced changes in the pupil diameter. When implanted, the first sensor is disposed completely within the pupil; even when fully constricted, the pupil does not occlude the first sensor, allowing the sensor to make precise measurements of ambient luminous flux levels. The pupil occludes part of the second sensor's active area(s) as the pupil dilates and constricts. As a result, the second sensor measures both ambient luminous flux and pupil diameter. A processor estimates the pupil diameter and determines whether it's changing in response to accommodative stimuli or other factors by comparing to predetermined values. The sensor system sends a signal to an optical component, which in turn can respond by changing optical power to focus for near vision upon detection of accommodative stimuli. | 09-19-2013 |

20130220778 | CONVEYOR HEAD AND TAIL DRIVE ROLLER SYSTEM - An incline conveyor that includes driven rollers at both the input (tail) end and the output (head) end of the conveyor that are powered by a single power source. Power is transmitted along the length of the conveyor with a driveline that distributes power to both the input and output drive rollers. The position of the drive rollers is adjustable to tension and track the conveyor belt. The position of the gearbox is also adjustable to maintain tension on the drive belt. The resulting conveyor drive mechanism allows cleated belt conveyors to be longer and transfer at higher capacities. | 08-29-2013 |
