摘要:
A method and instrument to irradiate a light adjustable lens, for example, inside a human eye, with an appropriate amount of radiation in an appropriate pattern by measuring aberrations in the system containing the lens; aligning a source of the modifying radiation so as to impinge the radiation onto the lens in a pattern that corresponds to the aberration; and controlling the quantity of the impinging radiation whereby to decrease the aberration. The quantity of the impinging radiation is controlled by controlling the intensity and duration of the irradiation. The pattern is controlled and monitored while the lens is irradiated.

摘要:
This invention provides a high energy radiation system which produces UV radiation comprising a selectively attenuating material which increases the ratio of desired to undesired radiation to reduce the radiation damage to a target by selectively attenuating at least 30 percent of the radiation from greater than 200 up to 240 nm which impinges upon said attenuating material, and directs greater than 50 percent of the radiation from 240 nm to 280 nm which impinges upon said attenuating material.
摘要:
A system for providing diffuse illumination in the inspection of ophthalmic lenses for use in conjunction with a computer-based lens inspection apparatus. Below a package containing an ophthalmic lens in deionized water is an optical diffuser made of flashed opal and below that a light source such as a strobe light. The strobe lamp firing is initiated by the image processing system which is in turn triggered by a signal generated by the arrival of a package containing a lens to be inspected. In the preferrerd embodiment, an arc tube is employed wherein light output diminishes by darkening only in one end of the tube, that end placed outside the reflector.
摘要:
A lens inspection method and apparatus comprising a pallet having wells for receiving one or more lens containers at the receiving point. A conveyor achieves uniformity of pallet motion when transporting the lens. The pallet wells includes holes that pass through the pallet. These holes, along with a side driven transport system, make possible an arrangement of a lamp and camera on opposite sides of the lens for capturing an image of a lens. A computer implemented algorithm processes the digitized image to determine the acceptability of the lenses. A lens disposition mechanism uses a signal generated by the computer and indicates lens acceptability to disposition the lens by physically separating a container with an acceptable lens from an unacceptable lens. After disposition of containers, the pallet is returned by conveyor to the lens receiving point.
摘要:
An automated inspection system for inspecting packages, such as blister packages, to verify the presence therein of products, such as contact lenses, prior to heat sealing of the blister packages. The automated inspection system includes a transport and ejector mechanism for ejecting any defective packages determined by the automated inspection system not to have a product therein. The automated inspection system includes an optical inspection station at which packages are optically inspected by video cameras to verify that a product is, in fact, present in each package base. A package conveyor system is provided for conveying the packages by the optical inspection station. Following the optical inspection station, an ejector ramp of the transport and ejector mechanism is selectively switchable between a first raised position in which package bases are passed on for further processing, and a second lowered position in which defective packages are transferred from the package conveyor system to the ejector ramp and a buffer area for ejected packages.
摘要:
Some embodiments pertain to a projectile and method that includes a flight vehicle and a propulsion system attached to the flight vehicle. The propulsion system includes a plurality of motors that propel the projectile. A guidance system is connected to the propulsion system. The guidance system ignites an appropriate number of the motors to adjust the speed of the projectile based on the location of the projectile relative to a desired destination for the flight vehicle. In some embodiments, the flight vehicle is a kinetic warhead. The projectile may be an interceptor that includes a first propulsion stage, a second propulsion stage and a third propulsion stage that includes the third propulsion system. The number of booster motors that will be ignited by the guidance system depends on the speed that the projectile needs to be adjusted to in order to maneuver the projectile to a desired location.
摘要:
The 6-axis position and attitude of an imaging vehicle's detector assembly is measured by mounting the detector assembly on a compliant isolator and separating the main 6-axis IMU on the vehicle from a secondary IMU comprising at least inertial rate sensors for pitch and yaw on the detector assembly. The compliant isolator couples low-frequency rigid body motion of the vehicle below a resonant frequency to the isolated detector assembly while isolating the detector assembly from high-frequency attitude noise above the resonant frequency. A computer processes measurements of the 6-axis rigid body motion and the angular rate of change in yaw and pitch of the isolated detector assembly to mitigate the drift and noise error effects of the secondary inertial rate sensors and estimate the 6-axis position and attitude of the detector assembly.
