Patent number: 11827009Abstract: Apparatus and method for the screen printing manufacture of a layer of silicone material. The method and apparatus provide for the deposition of a layer of silicone material having a controllable thickness and shape profile as determined by a template forming part of a screen printing assembly. The present apparatus and method provide a fully controlled automated or semi-automated manufacturing process enabling the deposition of a silicone layer onto a substrate layer serving as a conveyor to transport the silicone layer between different units of the process line including a heating/curing unit, a drying unit and a lamination unit.Type: GrantFiled: March 10, 2020Date of Patent: November 28, 2023Assignee: TRIO HEALTHCARE LTDInventors: Lloyd Pearce, Stewart Lee

Publication number: 20210220175Abstract: A stent for use in the nasolacrimal duct of a patient's eye. The stent is used to maintain and improve the patency of the nasolacrimal duct The stent uses a hollow shaft to create a fluid pathway from the punctum to the inferior meatus. Either the superior or inferior punctum can be selected for insertion of the stent. An inserter is used to position the flexible stent into position. A guidewire attached to the inserter is removed from the stent and it transforms from its collapsed state to its deployed state. A first anchor stabilizes the proximal end of the stent to the punctum and ampulla. A second anchor stabilizes the proximal end of the stent near the interior meatus. The second anchor can take any of several deployed shapes, such as a pigtail or fins.Type: ApplicationFiled: January 14, 2021Publication date: July 22, 2021Inventors: Savan Pravin Patel, Jeffrey John Albertsen, Vasu Nishtala, Stewart Lee Love

Patent number: 10750319Abstract: The present disclosure provides for dynamically determining locations of an electronic device. For example, the electronic device may determine a location state transition condition using one or both of a location measurement or an activity status of the electronic device. The electronic device may further determine whether the location state transition condition satisfies a location state transition threshold triggering an entry or exit to or from a first location state. The electronic device may further transition from the first location state to a second location state different from the first location state based on a determination that the location state transition condition satisfies the location state transition threshold.Type: GrantFiled: March 11, 2019Date of Patent: August 18, 2020Inventors: John Stewart Lee, Peter John Cockerell
