  • Patent number: 5552842
    Abstract: A segmented objective vision test is administered to a patient for determining a quantitative measurement of vision capability in the tested segments. Human vision can be tested in separate segments of the total vision spectrum including contrast sensitivity, or color sensitivity testing. Thereafter, an emmetropic real world image is filtered into corresponding emmetropic image segments. These corresponding emmetropic image segments are degraded into degraded image segments in correspondence with the separate test results for each corresponding separate segment of the total vision spectrum. The degraded image segments are then added to produce an objectively altered real world image. This objectively altered real world image can then be compared to the real world image of the emmetrope and a record preserved of the patient's actual vision condition as evidenced by the objective vision test and the subsequent image processing.

  • Patent number: 5220849
    Abstract: A gravitational compensating system that eliminates gravitational torque of linked robotic arms is provided. A three arm embodiment is disclosed which rotates around a vertical reference axis. The second and third arm rotate around two separate horizontal axes. The gravitational compensating system compensates for the gravitational torque attributed to the second arm as it rotates about its horizontal swing axis and the gravitational torque attributable to the third arm as it rotates about its horizontal swing axis. The combined actuating and compensating systems for the second and third arm are housed in the base structure of the first arm. The compensating system also applies to two arm embodiments.

  • Patent number: 5138904
    Abstract: This invention relates generally to robots and specifically to a robot for spraying applications which has the ability to accurately follow trajectories that require high speeds and accelerations, a working envelope appropriate for processing the sides, top, and bottom of a large object such as an aircraft, an integrated revolute joint and actuator for supplying power to the movable components of the robot along protected, low maintenance power paths, a zero backlash drive, and a gravity compensating system which causes the robot to be neutrally balanced throughout its entire working envelope even while carrying a payload of significant weight.
