Abstract: A controlled access aerosolized particle enclosure for isolation of airborne contaminants includes a frame defining a patient isolation region over a patient bed. A linkage attaches the framed enclosure to a patient treatment vehicle, and a flexible elasticized barrier is suspended by the frame for enclosing the patient isolation region. The barrier is formed from deformable planer sheets of a flexible transparent material and extending adjacent to the patient treatment surface forming a draped edge around the bed or transport. A low pressure source is in fluidic engagement with the enclosure for reducing a pressure within the enclosure below that of ambient surroundings, such that the low pressure source provides a pressure for drawing the elasticized barrier against the patient treatment surface for restricting airborne particle passage from the enclosure to the ambient surroundings, but limits the negative pressure to avoid substantial deformation or collapse of the enclosure.

Abstract: Velocity controllers in accordance with embodiments of the invention enable velocity estimation for tracked objects. One embodiment includes a tracker controller, including: a processor; and a memory containing: a velocity tracker application; a state space describing relationships between measured locations, calculated locations, and changes in locations, where the calculated locations in the state space correspond to unoccluded points on the surface of the tracked object; wherein the processor is configured by the velocity tracker application to: pre-process the state space to identify a tracked object; estimate a velocity of the tracked object using a location history calculated from the measured locations of the tracked object within the state space and a motion model calculated from the state space; and return the velocity of the tracked object.

Abstract: Methods, systems, and apparatus, including computer program products, for searching indexed and non-indexed content. One method includes updating an index of a corpus of resources from time to time to generate an updated index for use by a search engine. Change data specifying changes made by users affecting resources are recorded. An index search result based on the most-recently updated index is received in response to a user search query. The change data is searched to identify any changes to the resources made by the user that relate to the search query and if any such changes are found, a revised search result is generated from the changes and the index search result and provided to the user as a response to the first query.
