  • Publication number: 20250139785
    Abstract: A system and method of generating training results using a vision system is provided. At least one training image is selected, in which the image includes at least one representative feature. A line-finding tool searches the at least one training image for the at least one representative feature using at least one caliper, and a projection signal is generated from projection data associated with the at least one caliper. A filter signal is generated from the projection signal. An index value is generated by finding an edge of the at least one caliper nearest to an expected feature.

  • Patent number: 11870171
    Abstract: 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.

  • Publication number: 20230325301
    Abstract: 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.

  • Patent number: 11119892
    Abstract: The present disclosure provides a method, apparatus, device and computer-readable storage medium for guiding symbolic execution. According to embodiments of the present disclosure, it is possible to determine the specific code region of the program, and obtain the program loop output of the program corresponding to the specific code region of the program by using the program inverse analysis method, so that it is possible to obtain the program loop input of the program corresponding to the specific code region by using the program loop predictor according to the program loop output of the program. In this way, the obtained program loop input of the program corresponding to the specific code region may be used to guide the symbolic execution to filter out impossible execution paths and jump out of the program code and reach the specific code region, thereby improving the reliability of the symbolic execution.
