Method and device for transmitting data using inter-pulse interval modulation technique
First Claim
1. A method for transmitting data by a subject sensor device in communication with one or more other sensor devices via a wireless network, the method comprising:
- detecting, by a sensor of the subject sensor device, a parameter of an environmental condition;
outputting, by the sensor, at least two data values indicative of the parameter to a communication controller of the subject sensor device, wherein the communication controller includes a transceiver to communicate with the one or more other sensor devices via the wireless network;
constructing, by the communication controller, a data packet having a pair of unique pulse markers and a silence interval for representing each of the data values, wherein the silence interval is indicative of a given data value and is provided between the unique pulse markers for the given data value, one of the pair of unique pulse markers, as a start marker, is provided at a start of the silence interval for the given data value, and the other one of the pair of unique pulse markers, as an end marker, is provided at an end of the silence interval for the given data value;
transmitting, by the communication controller, the start markers for each of the data values separately to mark the start of the silence interval for each of the data values such that the start marker for at least one of the data values is interleaved within the silence interval for another data value; and
transmitting, by the communication controller, after the silence interval for the given data value is complete, the end marker for the given data value to mark the end of the silence interval for the given data value.

Abstract
A method and device for transmitting data between wireless devices includes: generating and transmitting, by a first device, a data cluster signal having a signal identifier, a completion marker, and at least one silence interval provided between the signal identifier and the completion marker; receiving, by a second device, the data cluster signal; identifying, by the second device, a signal type and a transmission completion of the signal received; and decoding, by the second device, the silence interval into the data based on the signal type and a duration of the silence interval.

4. A sensor device communicating in a wireless sensor network, the sensor device comprising:
-
a sensor operably monitoring a parameter of an environmental condition, wherein the sensor outputs a data value indicative of the parameter; a communication controller including a processor and a transceiver, wherein the processor operates as; a sensor input operably receiving the data value from the sensor; a data encoder operably encoding the data value as a silence interval that is transmitted between at least two pulses; and a signal generator operably constructing a data packet for multiple types of signals and transmits each of the signals based on respective data packet and transmits the data packet via the transceiver; the signal generator operably constructing a data cluster packet for a data cluster signal that is among the multiple types of signals; the data cluster packet operably including the silence interval, a signal identifier, and a completion marker, wherein a start marker is provided at a start of the silence interval for a given data value and the completion marker is provided when the silence interval for the given data value is completed; the signal identifier and the completion marker operably including at least one pulse having a preset duration; and the start marker and the completion marker indicating the silence interval being transmitted between the signal identifier and the completion marker, wherein the start marker for each data value separately marks the start of the silence interval for the given data value such that the start marker for the given data value is interleaved within the silence interval for another data value, and wherein the constructed data cluster packet is transmitted to a receiving device so that the receiving device can determine the preset duration of the silence interval. - View Dependent Claims (5, 6, 7, 8, 9)
