Systems and methods for interactive viewing of three-dimensional content using anatomical tracking
Patent published on the 2025-03-06 in WO under Ref WO2025049989 by D3LABS INC [US] (Spencer Barry [us], Spencer Julian George [us], Egenberger Jeremy [us])
Abstract: Interactive viewing of three-dimensional content includes producing anatomical tracking data representative of the movement of an anatomical feature of a user, rendering of three-dimensional target content and manipulation of the target content in response to the anatomical tracking data such that the user perceives his self or her self to be changing location with respect to a scene or object or perceives being tracked by a virtual character. A system of interactive viewing includes a point clo[...]

Lidar sensor denoising for adverse conditions and/or nonsalient objects
Patent published on the 2025-03-06 in WO under Ref WO2025049190 by ZOOX INC [US] (Terefe Nehemia [us])
Abstract: Particulate matter, such as fog, snow, rain, steam, vehicle exhaust, debris (plastic bags), etc. may cause one or more sensor types to generate false positive solid surface detections. In particular, various depth measurements may be impeded by particulate matter. Identifying false positive return(s) may comprise clustering lidar points, determining differences in range indicated by two different lidar devices having lidar points in the cluster, determining first differences that are more negati[...]
Our summary: Lidar sensor denoising for adverse conditions and/or nonsalient objects by identifying and suppressing false positive solid surface detections caused by particulate matter such as fog, snow, rain, and debris.

Combining multiband signals in lidar systems
Patent published on the 2025-03-06 in WO under Ref WO2025049069 by SILC TECH INC [US] (Behroozpour Behnam [us], Asghari Mehdi [us])
Abstract: The LIDAR system outputs a system output signal and receives a system return signal that includes light from the system output signal that was reflected by an object located outside of the LIDAR system. The LIDAR system includes data lines that each carries a different preliminary channel signal. A selection of the preliminary channel signals is beating at a beat frequency. Each of the preliminary channel signals in the selection of the preliminary channel signals is generated from light include[...]
Our summary: Combining multiband signals in lidar systems involves utilizing bandpass filter components to process preliminary channel signals, resulting in the generation of channel signals on filtered data lines.
