Abstract: Systems and methods for tracking shape and orientation of an endoscope employ motion tracking sensors to track locations on the endoscope for use in determining real time shape and distal end orientation for display during navigation of the endoscope. An example system includes sensor units distributed along the endoscope and a control unit. The sensor units track motion of the endoscope locations and transmit resulting tracking data to a control unit. The control unit processes the tracking data to determine shape of the endoscope and orientation of the distal end of the endoscope. The control unit generates output to a display unit that causes the display unit to display one or more representations indicative of the shape of the endoscope and orientation of the distal end of the endoscope for reference by an endoscope operator during an endoscopic procedure.

Abstract: A system and a technique for recovering data from an input data stream without synchronization of an input sampling circuit to the input data stream determines a count of incoming samples (or frames) without generating a signal that is frequency-locked to the input data stream. A first clock is generated comprising a frequency that is greater than or equal to an expected frequency of the input data stream. A sample count is incremented in response to a sample received in the input data stream, and is decremented in response to a second clock signal. The second clock is generated from the first clock signal by passing the first clock signal if the sample count of the sample counter does not equal a predetermined sample count value and by blocking the first clock signal if the sample count equals the predetermined sample count value.

Abstract: Methods are disclosed for measuring ad impressions and receiving feedback on local ad assets inserted into a video transport stream at the set top box level. Each set top box stores the number of times an ad asset is inserted into an ad avail, along with a variety of other information relating to the playback of the ad asset. This measurement data is aggregated and sent to the ad decision service. In order to balance bandwidth usage, each set top box may report its measurement data to the ad decision service at a different time interval that is randomly selected. As it is desirable to receive the data in a timely manner, the random intervals may be confined so that all measurement data is reported within a predefined time period, such as for example over a twelve hour period.

The present system sends the set top box a decision matrix based on group memberships to allow the set top box to select and insert an ad asset targeted to the specific set top box.

Although not required, the computer system may process a query indicating a search scope and a molecular feature for an individual biological entity, and responsively process the molecular feature and the elements based on the search scope to induce a knowledge sub-graph for the individual biological entity.
