  • Publication number: 20230380715
    Abstract: Devices and methods for vascular navigation, assessment and/or diagnosis are disclosed where a location detection system generally includes an elongate body defining a lumen at least partially along a length of the elongate body. One or more sensors are positioned near or at a distal tip of the elongate body and one or more openings are defined along the elongate body in proximity to the one or more sensors. The one or more openings are configured to control a boundary distance between the one or more sensors and a fluid with a parameter of a known initial value when emitted from the one or more openings. A controller is in communication with the one or more sensors and is configured to track a change in the parameter relating to concentration over the one or more sensors and determine a position of the one or more sensors within a body.

  • Publication number: 20230285719
    Abstract: Devices and methods for vascular navigation, assessment, treatment and/or diagnosis are disclosed. The system generally comprises an elongate body sized for introduction and translation through a catheter lumen. One or more openings may be located at or in proximity to a distal end of the elongate body and a sensor is positioned at or in proximity to the distal end. The sensor is configured to measure at least one parameter of a mixture of a first fluid and a second fluid after the first fluid is emitted from the openings and into the second fluid when the distal end is advanced beyond a distal opening of the catheter lumen. A controller in communication with the sensor is configured to receive a signal indicative of the at least one parameter and is further configured to obtain a position of the sensor within a body of a subject based upon the signal.

  • Patent number: 11658438
    Abstract: An electrical connector can include a receptacle disposed in a housing. The housing can include a second end and an openable first end having at least two housing portions that are movable relative to each other between: an open position in which the receptacle is accessible by a plug through the housing portions; and a closed position in which the receptacle is not accessible by the plug through the housing portions. At least one of the housing portions can be biased toward the open position. The electrical connector can further include a grip coupled to the housing and movable relative to the housing between a first position that permits movement of the housing portions to the open position; and a second position in which the grip overlies the at least one biased-open housing portion such that the grip prevents movement of the housing portions to the open position.

  • Patent number: 11243857
    Abstract: A functional test execution engine (“FTEE”) may be configured to execute test scripts with respect to a server stack. The FTEE may be communicatively coupled to a test script storage device, which may store the test scripts. The FTEE may select one or more test scripts for execution with respect to the server stack. The one or more test scripts may carry out maintenance or diagnostic functions for the server stack. The FTEE may determine the processing resources of the server stack and, based on those processing resources, select a first set of test scripts from the one or more test scripts to execute. The FTEE may cause the first set of test scripts selected to execute with respect to the server stack in order to generate test script results. The FTEE may store the test script results for subsequent analysis and use during execution of subsequent test scripts.

  • Patent number: 10742798
    Abstract: In one embodiment, a method includes receiving sensor data from a number of sensors of the computing device. The sensor data corresponds to a particular state associated with the computing device. The method also includes determining a vector corresponding to the received sensor data; and comparing the vector with a pre-determined hyperplane. The hyperplane corresponds to a number of imminent uses of the computing device. The method also includes determining whether the particular state associated with the computing device corresponds to a particular one of the imminent uses of the computing device based on the comparison of the vector with the pre-determined hyperplane.

  • Patent number: 10686744
    Abstract: In one embodiment, a computing device selects a number of location updates from users which corresponds to a place. Each location update includes data indicating a geographic location that a user was at, and a time corresponding to when the user was at the geographic location. The computing device selects a first subset of the location updates which have geographic locations within a particular geographic area. For each location update in the first subset, the computing device determines a corresponding user and time. The computing device selects a second subset of location updates, each location update in the second subset corresponding to a user from the first subset, and a time within a threshold time of the time of the location update in the first subset. The computing device generates a probability map based on a distribution of geographic locations corresponding to the location updates in the second subset.

  • Patent number: 10620685
    Abstract: In one embodiment, a method includes receiving sensor data, while a mobile electronic device associated with a member of a social-networking system is in a first operation state, from one or more sensors of the mobile electronic device and obtaining characteristic information maintained by the social-networking system, the social-networking system being remote from the mobile electronic device. The method also includes verifying that a current user of the mobile electronic device is the member by comparing the sensor data to the characteristic information. The method also includes, in response to the verifying, transitioning from the first operation state to a second operation state.

  • Patent number: 10551478
    Abstract: In one embodiment, a method includes accessing at least two determinations of the location of a mobile computing device, with each determined location having been determined without reference to explicit location information manually input by a user of the mobile computing device. At least one first determined location is compared with at least one second determined location, with comparisons being made between location determinations made based on different location determination input. A functionality associated with the mobile computing device is allowed if the first determined location corresponds to at least one of the second determined locations.
