Publication number: 20240145652Abstract: Light-emitting devices including solid-state light-emitting devices, light-emitting diode (LED) devices, and LED packages with support elements for improved near-field and far-field emissions are disclosed. LED chips may be mounted to support elements in a manner that directs light through the support elements in desired emission directions. Support elements include optical structures that spread and mix light laterally within the support element. Optical structures include various light-altering layers, such as light-diffusing layers or light-reflective layers, that are arranged to effectively increase internal reflections for lateral spreading of light. Patterned arrangements of light-altering layers include portions that mask direct emissions for LED chips, thereby redistributing emissions laterally to increase near-field and/or far-field uniformity across an increased portion of emitting surfaces.Type: ApplicationFiled: November 30, 2022Publication date: May 2, 2024Inventors: Christopher P.

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
