Abstract: The present disclosure provides techniques for identifying regions of a three-dimensional (3D) printable object that are accessible by a tool. An example method includes receiving, from a remote computing device, an encrypted object file that includes a specification of a 3D printable object and receiving a request to process the encrypted object file to identify regions of the 3D printable object that are accessible by a tool. The method also includes obtaining a tool specification, computing a complement of the tool specification, and encrypting the complement of the tool specification to generate an encrypted comparison file. The method also includes computing an encrypted Minkowski sum of the encrypted object file and the encrypted comparison file to generate an encrypted result file that describes the regions of the 3D printable object that are accessible by the tool. The encrypted Minkowski sum is performed without decrypting the encrypted object file.

Abstract: The present disclosure provides techniques for processing a three-dimensional (3D) object file in a privacy-preserving manner. An example method includes obtaining an object file that comprises a specification of a 3D printable object, encrypting the object file using a public key to generate an encrypted object file, and sending, to a remote computing system, the encrypted object file and a request to process the encrypted object file to identify a characteristic of the 3D printable object. The method also includes receiving an encrypted result file from the remote computing system, wherein the encrypted result file comprises an encrypted Minkowski sum of the encrypted object file and an encrypted comparison file. The method also includes decrypting the encrypted result file using a private key corresponding with the public key to generate an unencrypted result file and processing the unencrypted result file to determine the characteristic of the 3D printable object.

Abstract: A system and method for captures of physical object data for environment modeling is provided. Mesh data is displayed over an image of a physical space for which a floorplan is to be generated. Instructions to mark an object are received and the instructions include a voice command and eye gaze or gesture. The mesh data is annotated with a marker based on the instructions by placing the marker at a location at which an object is to be identified. A floorplan of the space is generated based on the mesh data. The marker is placed in the floorplan.

Abstract: The present disclosure provides techniques for processing a three-dimensional (3D) object file or object model in a privacy-preserving manner. An example method includes receiving, from a remote computing device, an encrypted object file comprising a specification of a 3D printable object and receiving a request to process the encrypted object file to identify a characteristic of the 3D printable object. The method also includes obtaining an encrypted comparison file and computing an encrypted Minkowski sum of the encrypted object file and the encrypted comparison file to generate an encrypted result file that comprises information about the characteristic. Computing the encrypted Minkowski sum is performed without decrypting the encrypted object file. The method also includes sending the encrypted result file to the remote computing device.

Abstract: The present disclosure provides techniques for finding non-printable features in a three-dimensional (3D) printable object. An example method includes receiving a first encrypted file and a request to process the first encrypted file to identify non-printable features of a 3D printable object, wherein the first encrypted file is an encrypted complement of an object file that comprises a specification of the 3D printable object. The method also includes computing a first encrypted Minkowski sum of the first encrypted file and an encrypted minimum feature file to generate an encrypted intermediate file and sending the encrypted intermediate file. The method also includes receiving a second encrypted file that comprises an encrypted complement of the encrypted intermediate file and computing a second encrypted Minkowski sum of the second encrypted file and the encrypted minimum feature file to generate an encrypted result file that describes non-printable features of the 3D printable object.

Abstract: A building environmental sensor includes a sensing element for collecting measurements of environmental parameters such as temperature, humidity, light, sound or the absence or presence of gas. The sensor will: (a) detect that a data collection device is within a communication range of the sensor; (b) generate a data stream that includes the data that the sensor collected; (c) transmit the data stream to the first data collection device; (d) determine that a communication link between the sensor and the first data collection device was lost before the first data stream was fully transmitted; (e) detect that a second data collection device is within the communication range of the sensor; (f) generate a second data stream that includes the remaining data; and (g) transmit the second data stream to the second data collection device.

Abstract: A system and method for rapid sensor commissioning is provided. A three dimensional model of a space is generated. The space is scanned for identifiers associated with wireless sensors placed within the space. At least one of the identifiers associated with the wireless sensors is identified. The model is annotated with a representation of the sensor identified by the identifier, and data is collected from the wireless sensor.
