Abstract
A sensor enhanced communication device (200) is provided with a wake mode, a standby mode and sleep mode. The sleep mode is a periodic occurrence within the standby mode which places a cluster of sensors and transducers (202) into a state of arousal in which the sensitivity of the transducers and sensors is increased while the sampling rate is decreased. Incremental learning can occur during the sleep mode as well as basic memory transfers. Since the cluster does not have to re-acquire information upon entering wake mode, the overall power efficiency is improved.

- providing a wake mode, a standby mode and a sleep mode;
- in wake mode:
- receiving sensor variables from a server;
- providing full operation of the communication device in which sensor and transducer sensitivity is set for current environmental conditions without having to re-acquire sensor metric information;
- transferring contents from procedural memory to declarative memory.
- in standby mode:
- sending acquired sensor data to external server;
- moving contents from declarative memory to procedural memory;
- and
- enabling sleep mode;
- in sleep mode:
- increasing sensor and transducer sensitivity to acquire sensor data;
- reducing sensor and transducer sampling rates;
- transferring bidirectional data between declarative and procedural memory;
- and
- updating sensor variables with sensor metric information based on the acquired sensor data.
A portable two-way radio, comprising:
- a cluster of sensors and transducers;
- and
- a microcontroller providing a wake mode and a standby mode, the standby mode providing a periodic sleep mode to the cluster, the microcontroller placing the cluster into a temporary state of arousal during the sleep mode.
