Abstract: A system and method of creating a shape-conforming lattice structure for a part formed via additive manufacturing. The method includes receiving a computer model of the part and generating a finite element mesh. A lattice structure including a number of lattice cellular components may also be generated. Some of the mesh elements of the finite element mesh may be deformed so that the finite element mesh conforms to the overall shape of the part. The lattice structure may then be deformed so that the lattice structure has a cellular periodicity corresponding to the finite elements of the finite element mesh. In this way, the part retains the benefits of its overall shape and the benefits of lattice features without introducing structural weak points, directional stresses, and other structural deficiencies.

Abstract: A method for coordinating multiplexed communications among multiple piloted assets enlisted to a common mission and multiple requestors includes defining a mission based on a mission request received from at least one requestor via a software application, receiving enrollment requests for multiple asset pilots, receiving indications of geolocations associated with the asset pilots, matching the geolocations to the mission, and sending invitations to mobile devices of the multiple asset pilots based on the matching. Upon receipt of indications of acceptance from the asset pilots, operating multiplexed communications among the asset pilots and the requestor. The multiplexing can include relaying a first mission-related data from mobile devices of the asset pilots to a mobile device of the requestor via a common communication channel, and relaying a second mission-related data from the mobile device of the requestor to the mobile devices of the asset pilot via the common communication channel.

Abstract: A system and method for generating a computer-based united cellular lattice structure includes dividing a part volume into a number of adjacent subvolumes each having a side combination corresponding to a number and orientation of adjoining sides and non-adjoining sides. A modified lattice cell may be generated from a base lattice cell for each side combination of the subvolumes such that each modified lattice cell has face surfaces on faces thereof corresponding to non-adjoining sides and does not have face surfaces on faces thereof corresponding to adjoining sides. Copies of the modified lattice cells may then be generated and inserted into corresponding subvolumes such that the faces of the modified lattice cell copies having face surfaces are positioned along non-adjoining sides of the subvolumes and faces of the modified lattice cell copies not having face surfaces are positioned along adjoining sides of the subvolumes.

Next, biometric data of the user of the electronic device is detected. Biometric data can be data that represents one or more intrinsic physical or behavioral traits of a person. Thereafter, a report is created using the situation data and the biometric data, wherein the report includes evidence of the situation of the user of the electronic device.
