Publication number: 20250131640Abstract: Systems and methods for ray intersection against primitives are described. Primitive data is encoded efficiently into arrays of fixed-size data blocks using a data format which can be directly consumed for ray traversal. Vertex data in a block is pre-quantized and stored using a fixed-bit quantization grid. Mesh connectivity is encoded using a triangle strips based on control values representing triangle interconnectivity, and a compressed index buffer storing indices for vertices in each strip. Primitives can alternatively be quantized to generate primitive packets, that are stored compactly in, with, or near a leaf node of an acceleration structure. Low-precision intersection testers test a ray simultaneously against primitives to find candidate triangles that require full-precision intersection. Primitives that generate an inconclusive result during low-precision testing are retested using full-precision testers to definitively determine ray-triangle hits or misses.Type: ApplicationFiled: June 13, 2024Publication date: April 24, 2025Inventors: Joshua David Barczak, Mohammed Ahmed Muneam Al-Obaidi, David Kirk McAllister, Andrew Erin Kensler

Patent number: 12276991Abstract: This disclosure presents methods and systems of controlling a counter flow double pipe heat exchanger (DPHE) that includes a hot fluid pipe and a cold fluid pipe. In a method, a temperature error between a reference temperature and a temperature at an outlet of the hot fluid pipe of the counter flow DPHE is determined. A cold fluid mass flow rate is determined from an output of a proportional-integral-derivative (PID) controller based on the temperature error being input to the PID controller. The cold fluid mass flow rate is used for a cold fluid in the cold fluid pipe of the counter flow DPHE. The temperature error is controlled within a predefined range by utilizing parameters of the PID controller that are set by using a harmony search algorithm (HSA) to obtain a minimization of a cost function.Type: GrantFiled: December 14, 2021Date of Patent: April 15, 2025Assignees: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS, Yokogawa Saudi Arabia CompanyInventors: Sami El Ferik, Mustafa Al-Nasser, Rached Ben Mansour, Mohammed Ahmed Mohammed Eltoum

Patent number: 12261728Abstract: Aspects are provided for generation and transmission of MDMRS which allow matching of nonlinear model impact or properties between DMRS and data in DFT-s-OFDM waveforms as well as CP-OFDM waveforms. A UE transmits, to a network entity, an MDMRS generated from a DMRS. The MDMRS has a PAPR distribution matching a PAPR distribution of a signal including data in an uplink channel. A target PAPR of the MDMRS is based on a modulation scheme of the data. The UE also transmits the data in the uplink channel, where the uplink channel includes a PUCCH or a PUSCH. As a result of the ability of MDMRS to match the nonlinear impact of DMRS and PUSCH or PUCCH, the network entity may compensate for any EVM that may occur as a result of PAPR reduction by a nonlinear operator of the UE, and communication performance may thereby be improved.Type: GrantFiled: October 18, 2022Date of Patent: March 25, 2025Assignee: QUALCOMM IncorporatedInventors: Igor Gutman, Junyi Li, Tingfang Ji, Joseph Patrick Burke, Pushkar Bajirao Kulkarni, Abdelrahman Mohamed Ahmed Mohamed Ibrahim, Juergen Cezanne, Tao Luo, Peter Gaal
