A method for continually controlling the collective behavior of a set of computing devices in a distributed data processing system. A gateway node disseminates a specification request comprising a set of parameters to a set of computing devices. The gateway node may be unaware of the number and identity of individual computing devices. Each computing node receiving the request determines whether its attributes satisfy the predicates expressed in the specification request. If so, the node processes the parameters in the specification request and modifies its own behavior based on the values in the parameters of the specification request. Subsequently, the gateway node may also observe the quality of information (QoI) values communicated from the set of computing devices. The gateway node iteratively modifies the parameters disseminated in subsequent specification requests based on a divergence between a computed quality of information value and a desired quality of information value.

Once the location information is provided by the location information source it is provided to the requesting party.

Aspects of the subject disclosure are directed towards a video-based pulse/heart rate system that may use motion data to reduce or eliminate the effects of motion on pulse detection. Signal quality may be computed from (e.g., transformed) video signal data, such as by providing video signal feature data to a trained classifier that provides a measure of the quality of pulse information in each signal. Based upon the signal quality data, corresponding waveforms may be processed to select one for extracting pulse information therefrom. Heart rate data may be computed from the extracted pulse information, which may be smoothed into a heart rate value for a time window based upon confidence and/or prior heart rate data.

An open community model for information exchange enables individuals to plan and attain superior outcomes in a dynamic environment. A continually “world model” maintains information about the dynamic environment that is valuable for individuals of the open community. An open community model application publicizes a specification of relevant types of information it receives from suppliers and provides to consumers. Suppliers provide information consistent with the specification. Consumers utilize received information to reduce uncertainties or errors in the assumed environment so they can generate improved plans or improve their expected outcomes. Consumers give feedback to the open community model about the quality of information they received. A “world model” application combines information received to update and improve its understanding of the dynamic environment and its estimates of relevant parameters. The community model simplifies the creation and operation of information markets where innovative products are naturally selected and economically reinforced.

Methods and apparatus include cooperatively encoding digital data between collaborating parties. By prior agreement, the parties take turns encoding portions of a given payload (e.g., document), until all portions have been encoded, thereby transforming the payload from a native encoding to a new, composite encoding. Choreography rules facilitate the process. Each party is free to use its own processing scheme. The use of a lookback or chaining step enables each party to impart a quality of informational entanglement to the output during its construction. By virtue of these features and attendant synergies, the resultant jointly encoded digital data enjoys certain novel cryptographic properties in addition to serving as a record of interaction between parties. To decode the data, the process is reversed. Third parties are optionally employed to mediate aspects of the process. Noise and padding, such as watermarks or copyrights, may be added variously to the encoded digital data. Encoding schemes include encryption or compression algorithms.
