Abstract: An interest vector directed from a source profile to a target profile, and hints associated with the interest vector, are received. A profile filter is generated based on the hints. Profiles of a network are filtered, creating a set of profiles, each having attributes matching the hints. A first number of profiles in the set of profiles is calculated. Second hints are received, based on the first number, the second hints associated with the interest vector. A second profile filter is generated based on the second hints, and used to filter the profiles of the network, creating a second set of profiles. A second number of profiles in the second set of profiles is calculated. An interest alert is generated based on the second number, the interest alert including data sufficient to directly or indirectly identify the source profile and configured to notify the target profile about the interest vector.

Abstract: In an embodiment, the present invention provides a device that identifies cardiovascular dysfunction of a subject. The claimed device comprises a controller, a transducer, and a processor. The controller initiates collection of a plurality of data related to a physiological condition. The transducer collects data over a plurality of cycles and transfers the data to the processor, which reduces the received data signal into an output using a novel formula. In an example the data correlate with data that are directly related to cardiovascular dysfunction but that are of limited use.
