Patent number: 9210968Abstract: Systems, methods, and computer-readable storage media for applying an adhesive film to the sole of shoes. Application of a portion of the adhesive film can be performed by receiving a shoe on top of the adhesive film, which in turn is above a plate and compressible pins. Upon receiving the shoe, the plate is raised or lowered, and the compressible pins mark the perimeter of the sole of the shoe. The adhesive film is cut in a sole-shaped pattern due to the height differentiation, resulting in a sole-shaped portion of the adhesive film being adhered to the sole of the shoe.Type: GrantFiled: March 15, 2013Date of Patent: December 15, 2015Inventors: Tsontcho Ianchulev, Edward Y.

Publication number: 20140323995Abstract: This disclosure relates generally to methods and devices for use in treating eye conditions. In some embodiments, a site-specific therapeutic agent is mixed with a releasing agent with a dual syringe apparatus in order to achieve homogeneity. Once mixed, the site-specific therapeutic agent and releasing agent can be either dispensed directly within an area of the eye or within an implant. The implant can be at least partially filled with the site-specific therapeutic agent and releasing agent either prior to or after implantation into the eye. Some ratios of site-specific therapeutic agents to releasing agents are disclosed which provide various releasing profiles of the site-specific therapeutic agent within the eye.Type: ApplicationFiled: April 23, 2014Publication date: October 30, 2014Applicant: TRANSCEND MEDICAL, INC.Inventors: Luke Clauson, Tsontcho Ianchulev, Nathan White, Richard S.
