Patent number: 11921064Abstract: The invention relates to a detection arrangement, a detection system comprising said arrangement, and a method of processing data from said arrangement. The detector arrangement disclosed comprises at least one array of detectors, wherein the detectors are configured to detect photons emitted from an object as a result of positron annihilation due to irradiation of the object with photons of a predetermined energy. Each detector in the array is linked to or associated with one or more other detector in the array to define a region of interest (RoI). The detector arrangement comprises or is communicatively coupled to a coincidence trigger unit which is configured to register or determine a coincidence in response to receiving detection signals from two different detectors forming part of the same RoI and indicating detection of substantially back-to-back co-linear and co-incident photons in the RoI.Type: GrantFiled: December 11, 2019Date of Patent: March 5, 2024Assignee: University of JohannesburgInventors: Simon Henry Connell, Martin Nkululeko Hogan Cook, Richard Charles Andrew

Patent number: 10288521Abstract: This invention relates to a force and moment balance (1) including a support (9) therefor and more specifically, but not exclusively, to a force and moment balance (1) and a support (9) therefor for a wind tunnel. Force and moment balances are known in the art and are typically used in wind tunnels to measure the force and moment loads on a model in the wind tunnel. A problem with current balances is that there is inherent vertical movement associated with horizontal force. According to the invention, the balance (1) has a fixed end (3) and a movable end (6) with a number of supports (9) between the fixed end (3) and the movable end (6). Each support (9) includes compensation means to compensate for resultant movements caused by lateral movement of the movable end (6) relative to the fixed end (3).Type: GrantFiled: May 13, 2015Date of Patent: May 14, 2019Assignee: UNIVERSITY OF JOHANNESBURGInventors: Jules David De Ponte, Frederik Francois Pieterse
