First Claim
Patent Images
1. A sensor, comprising:
- one or more components to;
encode data using a first encoding scheme,the first encoding scheme including encoding a data bit, included in the data, using a first chip sequence that corresponds to a first set of current levels,where a second encoding scheme is used by another sensor to encode other data,the second encoding scheme including encoding a data bit, included in the other data, using a second chip sequence that corresponds to a second set of current levels,the first chip sequence and the second chip sequence being different chip sequences; and
modulate a current, based on the first set of current levels, to provide the encoded data.

Abstract
A sensor may encode data using a first encoding scheme. The first encoding scheme may include encoding a data bit, included in the data, using a first chip sequence that corresponds to a first set of current levels. A second encoding scheme may be used by another sensor to encode other data. The second encoding scheme may include encoding a data bit, included in the other data, using a second chip sequence that corresponds to a second set of current levels. The first chip sequence and the second chip sequence being different chip sequences. The sensor may modulate a current, based on the first set of current levels, to provide the encoded data.

8. A control unit, comprising:
a receiver to; receive encoded data provided by a sensor, the encoded data having been encoded by the sensor based on an encoding scheme associated with a portion of a Hadamard matrix; and decode the encoded data using the portion of the Hadamard matrix. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method, comprising:
-
encoding, by a first sensor, first data using a first encoding scheme, the first encoding scheme including encoding a data bit, included in the first data, based on a first chip sequence that corresponds to a first set of current levels; encoding, by a second sensor, second data using a second encoding scheme, the second encoding scheme including encoding a data bit, included in the second data, based on a second chip sequence that corresponds to a second set of current levels, the first chip sequence being different than the second chip sequence; and decoding, by a control unit, the encoded first data based on the first encoding scheme and the encoded second data based on the second encoding scheme. - View Dependent Claims (16, 17, 18, 19, 20)
