Abstract: Described herein is an energy harvesting system comprising a transducer and a processor. The transducer generates an electric signal from ambient energy. The processor is configured to process the electric signal to perform pattern recognition of the electric signal so as to determine and output a characteristic of a source of the ambient energy. The pattern recognition comprises statistical analysis and frequency domain analysis.

Abstract: Described is device for monitoring an activity. The device comprises a transducer that generates electric power from the activity and an energy store that stores the electric power over consecutive time intervals. The device further comprises a transmitter that periodically transmits the stored energy as an activity pulse indicative of an activity classification.

Abstract: A system for controlling congestion is disclosed, the system comprising a host computer (108C) adapted to run concurrent processes (402, 412) and a gateway (100C) through which communications traffic from the concurrent processes (402, 412) to corresponding concurrent processes is directed. The gateway comprises means (906) for determining available bandwidth on connections (106) between the gateway and the corresponding concurrent processes, means (910) for determining host rate control information dependent upon said available bandwidth, and means (906) for communicating the host rate control information to the host computer (108C). The host computer (108C) comprises means (406, 416) for independently controlling traffic from each said concurrent process (402, 412) to the corresponding concurrent process according to the host rate control information.
