Sensor devices and methods for transmitting sensor data, apparatus and method for controlling a sensor device, apparatuses and methods for decoding a sensor signal

An apparatus for decoding a sensor signal that comprises sensor data, wherein the apparatus comprises:

• processing circuitry configured to:
• calculate a unit time based on a first time interval of the sensor signal between a first signal edge of a first type and a first signal edge of a second type, a second time interval of the sensor signal between the first signal edge of the second type and a second signal edge of the first type, a first reference value represented by the first time interval, and a second reference value represented by the second time interval;
• calculate a compensation time based on a time difference between the first time interval and the second time interval, and a multiple of the unit time that is proportional to a difference between the first reference value and the second reference value;
• calculate a first data value based on the unit time and a difference between the compensation time and a third time interval of the sensor signal between the second signal edge of the first type and a second signal edge of the second type;
• and
• decode the sensor signal based on the unit time, the compensation time, and the first data value.

An apparatus for decoding a sensor signal that comprises sensor data, wherein the apparatus comprises:

• processing circuitry configured to:
• calculate a first data value based on a reference value and a ratio of a first time interval, of the sensor signal between a first signal edge of a first type and a second signal edge of the first type, to a unit time,
• wherein the unit time is related to a time base of the apparatus, and
• wherein the reference value is represented by a leading time interval of the sensor signal between the first signal edge of the first type and a first signal edge of a second type;
• and
• decode the sensor signal based on the first data value.
