Abstract
A sensor comprises a transmitter to transmit signals over a communication path, the sensor further capable to receive signals from the communication path, wherein the sensor is configured to communicate sensor data having a nibble data signal format at the transmitter in response to a trigger signal received at the sensor.
Claims22
A sensor, comprising:
- circuitry configured to determine if a sensor identification in a request signal received from a controller matches an assigned identification of the sensor;
- and
- a transmitter configured to, if the received sensor identification matches the assigned sensor identification, and in response to a trigger signal in the request signal, start to transmit a synchronization signal to the controller, and after reaching a predetermined sensor internal count value, transmit a trailing edge of the synchronization signal, wherein a length of the synchronization signal, from the trigger signal to the trailing edge, indicates a time base or clocking speed of the transmitter, and the synchronization signal indicates a communication synchronization between the controller and the transmitter.
A system, comprising:
- a controller configured to transmit a request signal having a sensor identification;
- and
- a sensor configured to:
- determine if the sensor identification in the request signal matches an assigned identification of the sensor;
- and
- if the sensor identification in the request signal matches the assigned sensor identification of the sensor, and in response to a trigger signal in the request signal, start to transmit a synchronization signal to the controller, and after reaching a predetermined sensor internal count value, transmit a trailing edge of the synchronization signal, wherein a length of the synchronization signal, from the trigger signal to the trailing edge, indicates a time base or clocking speed of the transmitter, and the synchronization signal, and the synchronization signal indicates a communication synchronization between the controller and the transmitter.

A method, comprising:
- transmitting, by a controller, a request signal having a sensor identification;
- and
- determining, by a sensor, if the sensor identification in the request signal matches an assigned identification of the sensor;
- and
- if the sensor identification in the request signal matches the assigned sensor identification of the sensor, and in response to a trigger signal in the request signal, start transmitting by the sensor a synchronization signal to the controller, and after the sensor reaches a predetermined internal count value, transmitting a trailing edge of the synchronization signal, wherein a length of the synchronization signal, from the trigger signal to the trailing edge, indicates a time base or clocking speed of the transmitter, and the synchronization signal indicates a communication synchronization between the controller and the sensor.
