Abstract: A micro-watt class sensing device uses host-computer Input/Output (I/O) capabilities when transferring data to/from the host-computer directly from/to memory in the sensing device. This capability allows data to be directly transferred (downloaded/uploaded) to/from the host system at a higher rate when a host system is present.

Abstract: The invention relates to a system and method of a health monitoring network which automates detection of faulty or failed sensors using real-time fault checking on a dynamically registered sensor data stream. The monitoring system and sensor network can provide a one-touch system to notify users when a sensor requires attention, without prior knowledge of the operational characteristics, installation method or configuration of sensors in the network. The network uses a decision engine to assist in maintenance according to a profile based on individual preferences and capabilities.

Abstract: A conversation detector and detection method is based on voice band energy detection. The detector is formed of a signal preconditioner, a comparator and an analysis unit. The comparator generates signal pulses reduced in resolution and sample rate (e.g., single bit data) and indicative of energy level and/or duration of activity detected in subject audio signals. The analysis unit determines from the generated signal pulses whether a conversation exists in the subject audio signal. The detector is also able to adapt to environmental noise change, automatically calibrate and operate in low power consumption mode.
