    摘要： A mesh device for receiving and processing a private beacon message, which can be represented by one or more Bluetooth Low Energy mesh packets. Upon receiving the private beacon message, the mesh device decrypts a first portion of the private beacon by using a first encryption key corresponding to a first subnet, wherein the first portion comprises an initialization vector (IV), in the form of an index or other indicator. The decrypting using the first encryption key results in a first decrypted value for the IV index. The mesh device then determines whether the first decrypted value for the IV index is valid or invalid. If the mesh device determines the first decrypted value to be valid, the mesh device proceeds with authenticating the data contained in the private beacon message.

    摘要： In a 3D-printing system, a deposition head comprising a band assembly having a body and a band for compacting a filament onto the surface of an object being manufactured. One or more actuators are mounted on the assembly body and are used to shape the band to a desired contour. The band is connected to the one or more actuators, is curved toward the surface of the object to enable contact with the surface, and is capable of being driven along its length by one or more drive wheels that are under the control of a controller. The drive wheels are configured to advance the band along its length by a first distance and in response to a first signal from the controller. The controller provides the first signal based on an estimate of thermoplastic build-up on a portion of the band that overlaps the point of compaction.

    摘要： A system and method for ray launching in electromagnetic wave propagation modeling. A data-processing system receives a dataset that is representative of a plurality of structures within an environment. The plurality of structures is defined in the dataset as having a plurality of surfaces. The system then partitions each surface in the plurality of surfaces into a plurality of tiles. The system pre-computes whether i) the reference point of each corresponding tile in each plurality of tiles of each surface is visible or not from ii) the reference point of each possible spawning tile in each other plurality of tiles. The system then projects a first set of ray tubes based on the pre-computed visibility. The system evaluates the incidence of bounced ray tubes at a predetermined receive point within the environment and then presents a propagation result that is based on the evaluated incidence of the bounced ray tubes.

    摘要： A technique for additive manufacturing that avoids the necessity of having a build plate. The illustrative embodiment comprises two anchor plates from which a structure is constructed that forms at least the initial support for the object to be manufactured. The envelope of the structure can be a cylinder, a box, an n-sided prism, a hyperboloid of one sheet, a cone, the frustum of a cone, a pyramid, and the frustum of a pyramid.

    摘要： A sensor and control platform includes a smart wall plate and a variety of optional sensor/control elements that removably couple to and interact and communicate with the smart wall plate to enhance the functionality and power of a premises automation system. The smart wall plate contains a plurality of sensors, a microprocessor control unit, and a wireless transceiver. The optional sensor/control elements can be a control dial, a monitoring device, or a camera. The smart wall plate can dictate the functionality of the optional sensor/control elements or the optional sensor/control elements can alter the functionality of the smart wall plate.

    摘要： A technique for simplifying structure data for representing an environment. Polyhedrons can make up structure data used in an application such as modeling, visualization, and navigation. Consequently, the operations that are performed on the data often involve determining, for each polyhedron that defines a structure such as a building, whether the polyhedron obstructs a line-of-sight line between a first point in space being considered in the application and a second point. In order to determine whether a polyhedron obstructs a line-of-sight line, a data-processing system operating on the structure data must determine whether any walls of the polyhedron intersect the line. Thus, the more polyhedrons there are or the more vertices that are in each polyhedron, the more walls there are, and the more intersection checks are required, thereby adding to the computations. The disclosed technique reduces the number of walls by simplifying objects that make up the structure data.
