Publication number: 20220164637Abstract: Introduced here are integrated circuits (also referred to as “chips”) that can be implemented in a neural processing unit. At a high level, the goal of these chips is to provide higher performance for machine learning algorithms than conventional processing units would. To accomplish this, the neural processing unit can include multiple computing components, each of which is able to independently determine the overlap between encoded data provided as input and values stored in a memory.Type: ApplicationFiled: November 19, 2021Publication date: May 26, 2022Inventors: Harold B.

Patent number: 11253350Abstract: A ligament assembly (2) comprising a resilient element (20) connected to a bone anchor (4) and a ligament (18), the resilient element (20) acting m a cantilever and resisting toads transmitted between the bone anchor (4) and the ligament (18) by virtue of the resistance to bending of the resilient element. The ligament (18) may comprise an artificial ligament (18) which is adapted to replace a human or animal ligament. The resilient element (20) may comprise a spiral spring and may act as a biasing element/shock absorber operatively coupled to the artificial ligament (18) to control the effective stiffness of the artificial ligament (18). Consequently, the resilient element (20) enables an effective stiffness of the artificial ligament (18) to be achieved that more closely approximates the stiffness of a natural ligament.Type: GrantFiled: November 6, 2019Date of Patent: February 22, 2022Assignee: Biomet UK Healthcare LimitedInventors: Christopher Dodd, David Wycliffe Murray, John O'Connor, Russell Lloyd, Mona Alinejad
