Patent number: 11870171Abstract: A high density edge connector that provides robust operation and good signal integrity. The connector is configurable to have sections tailored for high speed signals, which may be differential, or low speed signals. The connector may be assembled from signal terminals and ground terminals, either of which may be mounted within an insulative housing of the connector at any location along a row aligned with a slot of a mating interface. Shield members or lossy members may optionally be included for high speed segments, either or both of which may be electrically coupled to the ground terminals. Insertion and retention force may be limited, despite a dense array of contacts pressing on a card inserted into the connector by shaping the portions of the signal or ground contacts that act as beams generating that force. Such force may be limited with twists in the beams and/or splitting the beam portions.Type: GrantFiled: December 1, 2018Date of Patent: January 9, 2024Assignee: Amphenol Commercial Products (Chengdu) Co., Ltd.Inventors: Rongzhe Guo, Tao Zeng, Qian Feng

Publication number: 20230325301Abstract: Embodiments generate effective mutation directions for fuzzing by using an abstract interpretation engine that for each of a set of input variables determines whether, for an input value range, a source code comprises a potential bug. The abstract interpretation engine generates a list of potential bugs that is provided to a machine learning engine (e.g., a reinforcement learning engine) that, iteratively for each potential bug, generates a learned input value range that is narrower than the input value range. The learned input value range is provided to the abstract interpretation engine, which updates the input value range, and to a fuzzer, which limits a search space for generating a set of seeds that is used to identify bugs in the source code.Type: ApplicationFiled: April 7, 2022Publication date: October 12, 2023Applicant: Baidu USA LLCInventors: Qian FENG, Zhaofeng CHEN, Zhenyu ZHONG, Kang LI
