Abstract
A sensor network may be configured to operate in extreme temperature environments. A sensor may be configured to generate a frequency carrier, and transmit the frequency carrier to a node. The node may be configured to amplitude modulate the frequency carrier, and transmit the amplitude modulated frequency carrier to a receiver.
Claims19
An apparatus, comprising:
- a plurality of sensors, wherein each of the sensors is configured to generate a frequency carrier;
- and
- a plurality of nodes, wherein each node in the plurality of nodes is connected to a corresponding one of the sensors, wherein each node is configured to:
- amplitude modulate the frequency carrier from a corresponding one of the sensors to uniquely identify that sensor;
- and
- transmit the amplitude modulated frequency carrier to a receiver, wherein each node in the plurality of nodes comprises:
- a first path including an amplitude modulator;
- and
- a second path including a code generator, wherein the amplitude modulator is configured to amplitude modulate the frequency carrier by a code sequence generated by the code generator.
6 more elements
An apparatus comprising:
- a sensor configured to generate a variable frequency carrier;
- a node connected to the sensor, wherein the node comprises:
- a prescaler configured to divide the variable frequency carrier by an integer per bit to create a divided signal;
- a code generator configured to generate a unique waveform using the divided signal;
- and
- an amplitude modulator configured to amplitude modulate the variable frequency carrier using the unique waveform and transmit the amplitude modulated variable frequency carrier to a receiver.
