li Lidar-based classification of object movement By www.freepatentsonline.com Published On :: Tue, 18 Aug 2015 08:00:00 EDT Within machine vision, object movement is often estimated by applying image evaluation techniques to visible light images, utilizing techniques such as perspective and parallax. However, the precision of such techniques may be limited due to visual distortions in the images, such as glare and shadows. Instead, lidar data may be available (e.g., for object avoidance in automated navigation), and may serve as a high-precision data source for such determinations. Respective lidar points of a lidar point cloud may be mapped to voxels of a three-dimensional voxel space, and voxel clusters may be identified as objects. The movement of the lidar points may be classified over time, and the respective objects may be classified as moving or stationary based on the classification of the lidar points associated with the object. This classification may yield precise results, because voxels in three-dimensional voxel space present clearly differentiable statuses when evaluated over time. Full Article

li Photo-crosslinked gellan gum-based hydrogels: preparation methods and uses thereof By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT This invention refers to photo-crosslinked hydrogel materials based in gellan gum suitable for tissue engineering and regenerative medicine applications or as drug delivery systems. Formulations of gellan gum with different degrees of acylation serve as precursor material for insertion of a polymerizable moiety. The materials are capable of free radical polymerization with a photo-initiator at mild temperatures and exposure to ultraviolet light, enabling control of reticulation and withstanding the encapsulation of human and animal cells and/or drugs, and any combination thereof. The physicochemical and biological properties can be adjusted by combining different formulations of gellan gum and reaction conditions. The matrix can be used either as an acellular or cellular system, dispensed manually or automatically by injection and crosslinked directly at the site of application, and can be processed using manual or automated systems in different types of scaffolds, such as hydrogels, fibers, 3D structures and micro- or nanoparticles.
