Abstract
A sensor system is configured to communicate at least partially protected sensor data over a communication interface. The sensor system includes a sensor element and a communication interface communicatively coupled to the sensor element. The sensor element is configured to provide sensor data in the digital domain. The communication interface is configured to generate a data package for transmission over the communication interface from the sensor data. The data package includes a data grouping comprising one or more nibbles related to the sensor data. The data package further includes a nibble indicia based on at least a portion of selected nibbles within the data grouping.
Claims20
A method for communicating at least partially protected sensor data over a communication interface, the method comprising:
- providing sensor data in a digital form;
- generating a data grouping comprising one or more nibbles related to the provided sensor data;
- generating a nibble indicia based on at least a portion of selected nibbles within the data grouping;
- forming a data package from the data grouping and the nibble indicia;
- and
- transmitting the data package over the communication interface.
A method for communicating at least partially protected sensor data over a communication interface in a sensor system, the method comprising:
- providing sensor data in a digital form using a sensor structure that is configured to ascertain a physical parameter of the sensor system;
- generating a data grouping comprising one or more nibbles related to the sensor data using a communication interface circuit that is communicatively coupled to the sensor structure;
- generating a nibble indicia based on at least a portion of selected nibbles within the data grouping using the communication interface circuit;
- forming a data package from the data grouping and the nibble indicia using the communication interface circuit;
- and
- transmitting the data package over the communication interface using the communication interface circuit.
