An anomalous process behavior manager uses statistical information concerning running processes to detect and manage process behavioral anomalies. This device can collect the heartbeat rhythm in at least one heart cavity, and analyze the collected rhythm so as to evaluate a value of heartbeat rate accordingly. By virtue of the space thus formed, air confined between the belt tooth and pulley tooth is allowed to escape in the transverse direction of the belt and does never produce bursting sound at the mesh of the belt tooth with the pulley tooth. In some embodiments, the memory cells may comprise non-ohmic devices; such as memristors and diodes.
