Title: Method of generating a hierarchical acceleration structure
Inventor: JOE DAVISON
IPC: G06T15/06
Filed: 2021-11-30
Abstract: When generating a node for a hierarchical acceleration structure for ray tracing the primitives (4a-h) in a 3D scene may be bounded by different shaped volumes (8a&8b and 6a & 6b). Sets of two or more bounding volumes in a scene are used to bound the primitives differently. Different sets of bounding regions may present different amounts of surface area (26a&26b and 28a&28b) for a ray entering the scene dependent upon the ray direction. Different sets are evaluated for each direction, and a set is selected to form a direction-optimised node with minimal presented surface area. Unnecessary intersection processing is avoided.

IPC: H02J50/20
Filed: 2022-04-11
Abstract: An electronic device includes an antenna module configured to perform millimeter wave communication with an external radio frequency (RF) device; an RF communication module which receives a mm-wave communication signal forwarded by the antenna module when the communication module is electrically connected to the antenna module; an RF charging module which receives a mm-wave charging signal forwarded by the antenna module when the charging module is electrically connected to the antenna module, and rectifies the wireless charging signal into a direct current (DC) output; and a processing module which controls the electrical connection between the antenna module, the RF communication module and/or the RF charging module. The processing module may variously include: a switching circuit, a time division duplex control circuit, an edge processor and edge interface, a frequency division circuit, filtering circuits or signal transmission circuits. Multiple functional modules may therefore share a set of antennas, which reduces the occupation of limited space in the electronic device, reduces cost and satisfies ultra-thin design requirements. A control method and computer-readable storage medium containing instructions for performing a control method are also provided.

Title: Bench-top time of flight mass spectrometer
Inventor: JASON LEE WILDGOOSE
IPC: H01J49/40
Filed: 2019-05-31
Abstract: A mass spectrometer is configured to operate an AC or RF voltage supply in: a low-attenuation mode in which a relatively high peak-to-peak amplitude AC/RF voltage is supplied to the electrodes of an ion guide 301 to provide relatively strong radial confinement of ions therein; and a high-attenuation mode in which a lower amplitude AC/RF voltage is supplied to the electrodes to provide weaker radial confinement of ions. The spectrometer may preferably switch between the low- and high- attenuation modes based on whether an ion signal detected by a downstream ion detector is above or below a threshold intensity or threshold ion impact rate. The ion guide may also comprise first and second axial paths, the second axial path 1802 being parallel to and displaced from the first 1801. Ions are urged from the first to the second axial path in a transition portion 1813 of the ion guide.

Abstract: Styrene polymer foam that is more environmentally acceptable, capable of making foam insulation over a wide range of densities, decorative and does not require the modification of existing equipment for high pressure operation is prepared using a mixed blowing agent of carbon dioxide plus ethyl chloride and optionally a fluorocarbon to provide a foam having primary cells and secondary cells defined by the struts and walls. The method of preparation involves heat-plastifying the styrene polymer and adding to the heat-plastified polymer a mixed blowing agent of carbon dioxide, ethyl chloride and optionally a fluorocarbon under a pressure sufficiently high to prevent foaming; reducing the temperature of the mixture and reducing the pressure of the mixture as it is extruded to form the foamed product.
