Abstract: Systems and methods for accessing and/or viewing selectable remote data such as video data are provided. In one aspect, the system searches and matches a user with a database of registered data providers, the matched data provider providing the user-requested data in real-time under negotiated terms. The data may be filtered before delivery to conform to additional requirements, such as removal of personally identifiable information. The data may be multi-media data, e.g., image, video, audio, and may be provided by the geographically dispersed data provider via mobile or stationary devices on demand or on a scheduled basis in response to a request from a user/consumer.

Abstract: The present invention discloses a system for performing proximity detection in computer simulations on parallel processing architectures utilizing a distribution list which includes movers and sensor coverages which check in and out of grids. Each mover maintains a list of sensors that detect the mover's motion as the mover and sensor coverages check in and out of the grids. Fuzzy grids are included by fuzzy resolution parameters to allow movers and sensor coverages to check in and out of grids without computing exact grid crossings. The movers check in and out of grids while moving sensors periodically inform the grids of their coverage. In addition, a lookahead function is also included for providing a generalized capability without making any limiting assumptions about the particular application to which it is applied. The lookahead function is initiated so that risk-free synchronization strategies never roll back grid events.
