Abstract: A pass-through hand tool includes a handle that includes a hollow bore extending therethrough. The tool includes a reversible main barrel, having a pair of socket ends and a hollow interior. The reversible main barrel is insertable into the hollow bore in either of two orientations to present one of the sockets. The tool includes a reversible secondary barrel having another pair of sockets, an external hexagonal screwdriver head, and a hollow secondary interior. The reversible secondary barrel is insertable into the hollow interior of the reversible main barrel in either of two orientations to present one of the associated sockets. The tool includes a reversible tertiary barrel having another pair of sockets with external hexagonal screwdriver heads and a hollow tertiary interior. The reversible tertiary barrel is insertable into the hollow interior of the reversible secondary barrel in either of two orientations to present one of the associated sockets.

Abstract: Systems and methods for tracking and re-identifying tracked subjects in an area of real space are disclosed. The method includes generating first and second reidentification feature vectors of a first subject identified from a first time interval from the respective first and second sequences of images as obtained from the first time interval. The method includes generating third and fourth reidentification feature vectors of a second subject identified from a second time interval from the respective first and second sequences of images. The method includes matching a second subject identified from a second time interval with the first subject identified from the first time interval when at least one of a first similarity score between the first and the third reidentification feature vectors and a second similarity score between the second and the fourth reidentification feature vectors is above a pre-defined threshold.

Abstract: Systems and methods for tracking inventory items in an area of real space are disclosed. The method includes receiving a signal generated in dependence on sensors. The signal indicates a change to a portion of an image of an area of real space. The method includes, in response to receiving the signal, implementing a trained location detection model to determine, based on inputs, whether an inventory item identified in the portion of the image has changed a position in the area of real space. The method includes implementing a trained item classification model to determine a classification of the inventory item. The method includes updating an inventory database with inventory item data determined in dependence on the classification of the inventory item to provide an updated map of the area of real space as a result of the received signal indicating the change to the portion of the image.

Abstract: Systems and methods for detecting a size of an inventory item in an area of real space are disclosed. The method includes receiving respective sequences of images of corresponding fields of view in the area of real space from a plurality of sensors. The method includes determining a two-dimensional plane in the area of real space by matching at least three points on a first image obtained by a first sensor and a second image obtained by a second sensor. The method includes selecting an inventory item, from the first image, for which a size is to be determined. The method includes warping the first image onto the two-dimensional plane. The method includes cropping out the selected inventory item from the warped image. The method includes, inputting, the cropped out image of the inventory item and another image of an inventory item to a trained size determination model.

Abstract: Systems and techniques are provided for tracking multi joint subjects in real space having a plurality of cameras. The field of view of each camera overlaps with at least one other camera. The plurality of cameras produce respective sequences of images of corresponding fields of view in the real space. A processing system is coupled to the plurality of cameras. In one embodiment, the processing system comprises image recognition engines receiving sequence of images from the plurality of cameras and generating corresponding arrays of joint data structures. A tracking engine is configured to receive the arrays of joint data structures and generate candidate joints having coordinates in the real space. The processing system includes the logic to identify sets of candidate joints having coordinates in the real space as multi-joint subjects in the real space.

Abstract: A distillation process for removing light ends impurities from alkyl esters of carboxylic acids wherein a purified ester is removed as residue, and wherein an inert gas and water are added to the overhead vapors from the distillation so as to facilitate separation of the light ends therefrom.
