Patent number: 11968311Abstract: In a Byzantine computing environment in which a database is sharded or partitioned among multiple clusters of computing nodes, consensus for and execution of data transactions (e.g., transactions that require and/or affect data of one or more shards) are achieved in a resilient manner. Within some clusters, multiple primary replicas concurrently propose transactions for processing in parallel by all replicas. For some multi-shard transactions, shards involved in the transactions may be logically ring-ordered; each shard in turn achieves consensus among its nodes to commit the transactions, and then executes its portion of the operation after consensus is obtained among all shards. For some other multi-shard transactions, involved shards first determine whether local data constraints are satisfied, after which data modifications are made in parallel.Type: GrantFiled: November 1, 2021Date of Patent: April 23, 2024Assignee: The Regents of the University of CaliforniaInventors: Mohammad Sadoghi Hamedani, Jelle Antonius Johannes Hellings, Suyash Gupta, Sajjad Rahnama

Publication number: 20240125952Abstract: A detector module is provided that can be used as part of a time-of-flight positron emission tomography (TOF-PET) system. The detector module comprises a plurality of emitter elements, each emitter element including an emitter composed of a substance that produces scintillation light and/or Cherenkov radiation in response to gamma photons and, coupled to each of two opposing ends of the emitter, a plurality of photodetectors.

Publication number: 20240125948Abstract: A single photon radiation detector is designed for a particular radiation source fluence, such that an incident radiation photon strikes a scintillator monolith, creating scintillation photons, which are amplified by appropriately sized channels of photomultipliers optically coupled to the scintillator monolith. The photomultiplier output is electronically shaped into a corresponding stream of scintillation pulses (otherwise referred to as scintillation photons) that pass through a comparator to produce a bitstream of the detected scintillation photons, which is sampled into a field programmable gate array (FPGA) acting as a giga-sample transceiver to produce time-to-digital conversions, capable of producing an output data stream of 10's-of-giga-samples per second or more. Appropriate design ensures sparsity of scintillation photon arrival, so that each photon in the bitstream corresponds to a single incident scintillation photon.Type: ApplicationFiled: October 12, 2023Publication date: April 18, 2024Applicants: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, National Technology & Engineering Solutions of Sandia, LLCInventors: Joshua W.

Publication number: 20240127568Abstract: This disclosure provides a precision-positioning/quality control system capable of measuring the exact position of any given mechanical component/part of any size or shape used during an assembly process. In one aspect, a process for performing high-accuracy localization and positioning of a rigid object is disclosed. This process can begin by receiving a full image of the object. The full image is then processed by a deep-learning module to identify a set of regions of interest on the object. Next, the identified regions in the set of regions of interest are subsequently processed to identify a number of surface points within each identified region and accurately estimate their positions. After sequentially processing all the regions of interest, the process subsequently generates an accurate position estimation for the object based on the combined set of identified high-precision surface points for the set of regions of interest.Type: ApplicationFiled: February 10, 2022Publication date: April 18, 2024Applicant: The Regents of the University of CaliforniaInventor: Iman Soltani Bozchalooi
