  • Patent number: 11944575
    Abstract: Embodiments generally relate to ophthalmic laser procedures and, more particularly, to systems and methods for lenticular laser incisions to form a top lenticular incision, a bottom lenticular incision of a lens in the subject's eye, an added shape between the top and bottom incisions where the added shape has no corrective power and a transition ring bisecting both the top and bottom lenticular incisions.

  • Publication number: 20230127288
    Abstract: An ophthalmic surgical laser system includes: a laser that produces a pulsed laser beam having a pulse energy and pulse repetition rate; a high frequency fast scanner; an XY-scan device; a Z-scan device; and a controller. The controller controls the high frequency scanner to produce a scan line having a scan width; controls the XY-scan device and the Z-scan device to carry out of first sweep of the scan line in a first sweep direction and to carry out a second sweep of the scan line in a second sweep direction that is not parallel to the first sweep direction thereby defining an overlap region. At least one of the pulse energy, repetition rate, XY-scan speed, and the scan width is varied so as to accelerate the cutting speed and reduce the exposure of ophthalmic tissue in the overlap region to multiple exposures of laser pulses configured to modify ophthalmic tissue.

  • Patent number: 6431549
    Abstract: A sealing method and apparatus involves positioning sealant carriers in a gap between first and second components to be sealed. Sealant is applied to a first major surface of the sealant carriers. As the first and second components are tightened together, the carriers are compressed and cause sealant to travel from the first major surface and through the carriers to a second major surface which is opposed to the first major surface. The sealant carriers may be positioned on respective carrier supports while sealant is being applied to the first major surface of the sealant carriers. The supports are used in initially positioning the sealant carriers in place and then are removed prior to tightening the first and second components together. The supports may include alignment mechanisms for use in aligning the sealant carriers with one of the first and second components. The sealant adheres the sealant carriers to such one of the first and second components following removal of the supports.

  • Patent number: 5046076
    Abstract: A card counter (10) prints card inventory information locally and communicates with a remote computer (43) for permanent storage and retrieval of inventory information. A microprocessor controller detects a counting error in response to the actual count failing to match a preset count, failing to match a precount information machine read from a machine readable precount label (130) attached to the cards (18), in the event of a phrase error from a pair of parallel scanning card sensor circuits (58, 59) or if the final counts of the two card sensor circuits (58, 59) do not match. In the event of detection of a counting error, an error indication is provided and entry of the count into an accumulator memory is inhibited. The present number is entered into memory by selectively entering an actual count into the preset memory. A pair of separate accumulators are provided for concurrently accumulating totals of two different groups of cards (18).
