Lidar near-field detection
Patent published on the 2026-06-11 in US under Ref US20260160863 by SEYOND INC [US] (Leng Xiandong [us], Wan Peng [us])
Abstract: A LiDAR system that includes an optical receiver and light detector including a first photodetector set of one or more first photodetectors disposed configured to detect return light corresponding to transmission light generated by the LiDAR system. The first photodetector set has a near-field blind zone corresponding to limited detection of return light corresponding to objects disposed in the near-field blind zone. The optical receiver and light detector may also include a second photodetector[...]
Our summary: The LiDAR system features a first set of photodetectors designed to detect return light but has a near-field blind zone. A second set of photodetectors is included to address the limitations of the first set. The second photodetectors are positioned closer to the window for improved detection of objects in the blind zone.

Attention-guided transformer architecture for fine-grained style representation in design systems
Published on 2026-05-01 by @OXFORD
Abstract: AbstractInterior design style recognition presents a challenging computational problem due to fine-grained inter-style similarities, complex spatial arrangements, and strong variability in materials, lighting, and layout. From a computational design and engineering perspective, accurately modelling such stylistic variations is essential not only for classification, but also for enabling semantic representation, retrieval, and analysis of design cases within data-driven design systems. However, e[...]
