The method may include receiving trajectory information associated with a planned flight, wherein the trajectory information comprises a series of trajectory vectors, each trajectory vector comprising time information, position information and velocity information. Identification of consequences of interest, and an extent of a region of interest for potential hazard areas may also be received. The method may include determining an upper bound of expected consequence for each population center based on a number of people in each population center subject to different consequences, determining one or more collective risk metrics for each population center, and a collective risk metric for all population centers.Type: ApplicationFiled: April 7, 2021Publication date: February 17, 2022Applicant: ACTA, LLCInventors: Erik LARSON, Tyler GRAS, Steven CARBON

Patent number: 10630466Abstract: A method implemented by computers includes exchanging a key between a first user and a second user. Ephemeral session keys are generated. The ephemeral session keys are generated by a first computer associated with the first user and a second computer associated with the second user. An encrypted key generation response is exchanged between the first computer and the second computer. A new session request is received. It is determined that there is a valid session state. It is confirmed that there is a valid user. It is determined that there is a valid session identification. Information between the first computer and the second computer is cryptographically exchanged in response to the valid session state, the valid user and the valid session identification.Type: GrantFiled: November 3, 2017Date of Patent: April 21, 2020Assignee: Hologram, Inc.Inventors: Patrick F.

Patent number: 10585570Abstract: A collaborative content management system allows users to create, edit, and share collaborative content items among a plurality of other users. The system enables a collaboration event between author client devices and recipient client devices. During a collaboration event, a collaborative content item is created by an author. The collaborative content item is converted into a model collaborative content item and stored in the collaborative content management system. Access to the model collaborative content item is shared with recipient client devices. A derivative copy of the collaborative content item is generated based on the model collaborative content item, for instance in response to a request from a user of a recipient client device. The created derivative collaborative content items are editable by users corresponding to the derivative collaborative content item such that edits made to a first derivative collaborative content item are not accessible to other derivative collaborative content items.Type: GrantFiled: May 22, 2017Date of Patent: March 10, 2020Assignee: Dropbox, Inc.Inventors: Erik Larson, Shehzad Daredia, Justin Hileman

Patent number: 8603613Abstract: A system and method for decorative elements having multiple visual appearances. The decorative elements may present different colors and/or other visual appearance characteristics and yet function as a durable construction material, like a traditional brick, tile or shingle. The decorative elements may receive a mechanical operation that permanently physically alters the decorative element, such as a cutting, sawing, drilling or molding operation, while the decorative element is functional to provide a controllable visual appearance both before and after the physical alteration. The decorative elements may be autonomous in that power needed to change visual appearance states can be gathered by an integrated energy harvesting device, such as a solar cell. A color chip system may be used to select decorative element features.Type: GrantFiled: October 23, 2009Date of Patent: December 10, 2013Assignee: Tesserae TechnologiesInventor: Erik Larson

Patent number: 8144232Abstract: A system and method provide interactive techniques for sharing digital photos, in which a user of a portable electronic device may seek out a location at which another electronic device was used to capture a photo. The captured image may then be displayed on a display of the user's electronic device by superimposing the photo on the display while the display functions as an electronic viewfinder for a camera assembly of the electronic device. The viewing of another person's photos is made to be an interactive and entertaining experience. The disclosed techniques combine the user's “real world” presence (e.g., location and viewing perspective) with the previously captured photo to create a fun and exciting experience that also may serve as a trigger for communication between the user and the person who took the photo.Type: GrantFiled: July 3, 2008Date of Patent: March 27, 2012Assignee: Sony Ericsson Mobile Communications ABInventors: Erik Larson, Julia Wilson, Fredrik Alstorp
