  • Patent number: 9930100
    Abstract: In one embodiment, a method includes accessing a first instance of content to be uploaded to a server, generating a second instance of the content from the first instance, automatically uploading to the server the second instance of the content, and automatically uploading to the server the first instance of the content in response to occurrence of a pre-determined upload condition. The first instance has a first file size and the second instance has a second file size that is smaller than the first file size. The upload of the second instance makes the content available for access at least in part by one or more second users at an immediate point in time.

  • Patent number: 8989842
    Abstract: A system to navigate an object traveling in an imaged subject is provided. The system includes a four-dimensional (4D) imaging system to create a first three-dimensional model of the acquired imaged data correlated relative to a time reference and defined relative to a first image coordinate system. A second imaging system creates a second three-dimensional model of the imaged subject defined relative to a second image coordinate system. A tracking system tracks movement and orientation of the object relative to a tracking coordinate system. A controller includes program instructions in combination with the processor operable to register the first and second image coordinate systems and the tracking coordinate system relative to a world coordinate system, and to combine the three-dimensional model created by the 4D imaging system with the three-dimensional model created by the second imaging system with a tracked location of the object relative to the world coordinate system.

  • Patent number: 8976819
    Abstract: A current detection module generates a first current detection signal of a first current flowing through a first power line and a second current detection signal of a second current flowing through a second power line. A multiplexer periodically switches between the two current detection signals in response to a control signal so as to output the first current detection signal within a first duration of each cycle of the control signal and the second current detection signal within a second duration of each cycle of the control signal. A signal processing module generates an energy accumulation signal according to the output of the multiplexer and a voltage detection signal of the voltage of a phase line. A control module provides the control signal to the multiplexer, and generates an effective value of the second current during the second duration.

  • Patent number: 8442619
    Abstract: A system and method for identifying errors while tracking instrument navigations is enclosed. The method may include assigning a plurality of virtual points to a plurality of sensors. At least one of the virtual points may be a non-fixed virtual point. The assignment of virtual points to sensors may be determined based on the medical instrument, or the medical instrument attachment, being used. Virtual point locations may be determined for the non-fixed virtual point. The locations of the non-fixed virtual point may be determined based on the medical instrument, or the medical instrument attachment, being used. The vector values for vectors terminating at the non-fixed virtual point may be adjusted. The field integrity values for the virtual points may be computed. If a field integrity value is greater than a threshold value, an error signal may be communicated.
