  • Patent number: 11813198
    Abstract: The first step for removal of cataracts generally is a capsulotomy—the removal of the anterior capsule of the eye lens. The circular capsulotomy incision tool provides a device that produces sharper cuts, with precise measurements, in an economical, reliable form without the need for complicated or expensive equipment, or extensive surgeon training or skill. The tool uses a resilient ring with a sharp cutting edge. The ring is collapsed, put in place through a corneal incision, and the original circular shape is allowed to return. The device uses a pulley mechanism to rotate the ring, enabling the cutting edge to reliably create a precisely edged capsulotomy.

  • Publication number: 20230278936
    Abstract: The method of curing reinforced concrete uses a liquid membrane-forming curing compound for the curing of reinforced concrete, but without fully coating the reinforced concrete with the curing compound, thus allowing for oxygen permeation through the reinforced concrete to effect passive layer formation on steel rebar embedded in the reinforced concrete. Prior to curing, a mask is applied to at least one surface of a slab of reinforced concrete, such that the mask covers about 10% of the surface area of the at least one surface. The at least one surface of the slab of reinforced concrete is then coated with a liquid membrane-forming curing compound. The liquid membrane-forming curing compound is allowed to dry, thus forming a curing compound layer on the at least one surface of the slab of reinforced concrete. The mask is then removed to form at least one uncoated region.

  • Patent number: 11730247
    Abstract: The combination hair band and comb assists people with activities of daily living (ADLs). The combination hair band and comb includes an elongate fabric hair band having a series of small internal combs that assist the user in combing/brushing their hair. A first end of the band is attached to one end of a spring clip, and the opposite second end of the band passes through a hole at the other end of the spring clip. In use, the hair band is tightened by pulling the distal end of the band through the hole in the spring clip. The spring clip is then fastened to maintain the band in the desired position. The internal plastic combs extend through an internal slit in the band and comb the hair as the band is pulled rearward through the user's hair, by the user grasping and pulling the distal end of the band.
