Patent attributes
A system including multiple devices that each have a sensor and are each configured to communicate with other devices. The system further includes a controller configured to provide command information that specifies a mode of operation of the devices. In a first mode of operation, the devices transmit communication signals and a given device modifies a strength of its communication signal from an initial strength to a final strength based on communication signals it receives from one or more other devices. And in a second mode of operation, the devices transmit communication signals and the given device dynamically adjusts a strength of its communication signal based communication signals it receives from one or more other devices and on measurements performed by the sensor in the given device.
