Publication number: 20240137153Abstract: A device may receive a PDCCH signal, may decode encoded bits of the PDCCH signal to generate coded bits, may reencode the coded bits, and may calculate a detection error probability of each coded bit at an output of soft demodulation. The device may calculate a channel decoding error probability that cyclic redundancy check bits are still attached to the coded bits, and may calculate an error probability of channel reencoding, of each coded bit, due to error propagation of polar decoding and reencoding. The device may calculate a probability density of a BMR associated with the coded bits, and may calculate a threshold based on the detection error probability, the channel decoding error probability, the error probability of channel reencoding, and the probability density of a BMR. The device may determine that the PDCCH signal is invalid based on the BMR being greater than the threshold.Type: ApplicationFiled: October 20, 2022Publication date: April 25, 2024Inventors: Jiancao HOU, Wei LI, Matthew David BROWN, Chi-ming LEUNG

Publication number: 20240085914Abstract: In various examples, techniques for determining perception zones for object detection are described. For instance, a system may use a dynamic model associated with an ego-machine, a dynamic model associated with an object, and one or more possible interactions between the ego-machine and the object to determine a perception zone. The system may then perform one or more processes using the perception zone. For instance, if the system is validating a perception system of the ego-machine, the system may determine whether a detection error associated with the object is a safety-critical error based on whether the object is located within the perception zone. Additionally, if the system is executing within the ego-machine, the system may determine whether the object is a safety-critical object based on whether the object is located within the perception zone.Type: ApplicationFiled: September 12, 2022Publication date: March 14, 2024Inventors: Sever Ioan Topan, Karen Yan Ming Leung, Yuxiao Chen, Pritish Tupekar, Edward Fu Schmerling, Hans Jonas Nilsson, Michael Cox, Marco Pavone

Publication number: 20240010196Abstract: In various examples, control policies for controlling agents may be learned from demonstrations capturing joint states of entities navigating through the environment. A control policy may be learned mapping joint states to control actions, where the joint states are between agents, and the control actions are of at least one of the agents. The control policy may be learned to define the mappings as control invariant sets of the joint sates and the control actions. The control policy may be used to determine one or more functions that compute, based at least on a joint state between entities, output indicating a likelihood of collision between the entities operating in accordance with the control policy. Using the output, current and/or potential states of the environment may be evaluated to determine control operations for a machine, such as a vehicle.Type: ApplicationFiled: March 14, 2023Publication date: January 11, 2024Inventors: Karen Yan Ming Leung, Sushant Veer, Edward Fu Schmerling, Marco Pavone

Patent number: 11674080Abstract: Disclosed are a transition metal complex, a polymer, a mixture, a composition and the use thereof, wherein the transition metal complex has a structure of the general formula as shown in formula (1): The transition metal complex has a novel structure, and is an iridium (III) complex comprising rigid cycloalkyl groups. Since this type of auxiliary ligand increases the rigidity and symmetry of a molecule, the rigidity of a molecule is increased relative to a common ligand without the cycloalkyl groups, and as such, the whole complex has better chemical, optical, electrical and thermal stabilities. At the same time, since the modification occurs on the auxiliary ligand, the effect on the wavelength of the luminous maximum peak caused by a main ligand is relatively low, and therefore, a saturated luminous color may be retained.Type: GrantFiled: December 6, 2018Date of Patent: June 13, 2023Assignee: GUANGZHOU CHINARAY OPTOELECTRONIC MATERIALS LTD.Inventors: Chi Ming Leung, Hong Huang, Junyou Pan
