  • Publication number: 20220051569
    Abstract: Described are techniques for determining measures of risk through a medium fidelity, fast running flight risk analysis system, for evaluating risk of a launch or reentry. 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.

  • Patent number: 10630466
    Abstract: 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.

  • Patent number: 10585570
    Abstract: 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.

  • Patent number: 10076669
    Abstract: An apparatus for treating a heart of a patient includes a first lead and at least a second lead for pacing the heart adapted to be in electrical communication with the heart. The apparatus includes a microcontroller in communication with the first and second leads which triggers the first lead at either different times or the same time from when the microcontroller triggers the second lead. Alternatively, the apparatus includes a microcontroller in communication with the first and second leads that determines heart volume, including stroke volume, end-systolic volume, and calculated values including ejection fraction, from admittance from signals from the first and second leads and uses the admittance as feedback to control heart volume ejected, as measured by stroke volume, calculated values such as ejection fraction, and control end-systolic volume, with respect to the first and second leads. A method for treating the heart of a patient.

  • Patent number: 8603613
    Abstract: 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.

  • Patent number: 8144232
    Abstract: 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.

  • Patent number: 8005640
    Abstract: An apparatus for performing a thermal response test to determine thermo-physical properties of a geothermal heat exchange resource. The apparatus includes a geothermal heat exchanger adapted to circulate a fluid through a loop in a sample borehole in the geothermal heat exchange resource and a variable speed pumping system capable of time-dynamic control of a fluid flow rate of the fluid. A multi-stage heating system is capable of applying a series of time-dynamic heat pulses to the fluid. The apparatus further includes a fluid temperature sensor and one or more fluid pressure, fluid density and/or fluid flow rate sensors, the sensors measuring data on the properties of the fluid that are predictive of the thermo-physical properties of the geothermal heat exchange resource.
