Abstract
A sensor system includes a signal sensing block including at least two sensing elements. Each of the at least two sensing elements is configured to generate an output that represents a first parameter associated with the sensor system. The sensor system also includes a data acquisition block configured to convert the outputs of the at least two sensing elements into digital data to be retrieved by a data retrieval block. The digital data is stored in one or more data registers of the data acquisition block. The sensor system also includes a data freeze block configured to cause the one or more data registers to refrain from updating with new data while the data retrieval block is retrieving the stored digital data.
Claims27
A sensor system comprising:
- a signal sensing block comprising at least two sensing elements, each of the at least two sensing elements configured to generate an output that represents a first parameter associated with the sensor system;
- a data acquisition block configured to convert the outputs of the at least two sensing elements into digital data to be retrieved by a data retrieval block, wherein the digital data is stored in one or more data registers of the data acquisition block;
- and
- a data freeze block configured to cause the one or more data registers to refrain from updating with new data while the data retrieval block is retrieving the stored digital data.
A method comprising:
- generating, by each of at least two sensing elements, an output that represents a first parameter;
- converting the outputs of the at least two sensing elements into digital data, and storing the digital data in one or more data registers;
- and
- causing the one or more data registers to refrain from updating with new data while the stored digital data is being retrieved.
A sensor system comprising:
- means for generating two or more outputs that each represents a first parameter associated with the sensor system;
- means for converting the two or more outputs into digital data and storing the digital data in a storage location;
- and
- means for causing the storage location to refrain from updating with new data while the stored digital data is being retrieved.
