Publication number: 20230293376Abstract: Systems and methods for synchronizing icons across interfaces for a dental chair are disclosed. In embodiments, a dental chair has a first interface and a second interface. Each interface includes a plurality of icons that graphically depict a stored position that can be actuated to command the chair to the stored position. The chair's position may be adjusted, and the adjusted position stored to one of the icons. Upon storage, the corresponding icon on both the first and second interfaces are updated to graphically depict the new stored position. Profiles that allow selection of different sets of stored positions may be provided. Other embodiments may be described and/or claimed.Type: ApplicationFiled: March 17, 2022Publication date: September 21, 2023Applicant: A-dec, Inc.Inventors: Michael John IRVING, Jason Joel ALVAREZ, Daryl Wayne FREIER, Scott Andrew MCCLELLAND, Bradley Jamin NELSON, Brett Douglas PETERSON

Patent number: 10854422Abstract: A method of forming a product using additive layer manufacture is provided. The method comprises forming the product as a series of layers, each layer being formed by fusing powder deposited as a powder bed by scanning the powder bed using a charged particle beam to form a desired layer shape. For each layer, the powder is fused by melting successive areas of the powder bed by scanning the charged particle beam using a combination of a relatively long-range deflector and a relatively short-range deflector, wherein the relatively long-range deflector deflects the charged particle beam over a larger deflection angle than the short-range deflector. Also provided are a corresponding charged particle optical assembly, and an additive layer manufacturing apparatus.Type: GrantFiled: October 18, 2017Date of Patent: December 1, 2020Assignee: RELIANCE PRECISION LIMITEDInventors: Nigel Crosland, Andrew McClelland, Phil Hoyle, Ian Laidler
