1. A sensor comprising:
- a clock generator configured to generate a clock within the sensor;
a receiver within the sensor that is configured to receive a signal from a controller separate from the sensor; and
a transmitter within the sensor that is configured to send a synchronization signal to the controller in response to the signal from the controller, the synchronization signal being based on the clock, and wherein a period between a first edge and a second edge of the synchronization signal is dependent on the clock and both edges are either rising or falling.

Abstract
A sensor may include a clock generator configured to generate a clock. A receiver may be configured to receive signals from a control unit, and a transmitter they be configured to send signals to the control unit. In one implementation, the transmitter is configured to send a synchronization signal based on the clock. A period between a first edge and a second edge of the synchronization signal may be dependent on the clock and both edges are either rising or falling.

2. A sensor system, comprising:
-
a sensor having a clock generator configured to generate a clock signal within the sensor; and a controller coupled to the sensor by way of a bus line, the controller configured to change a signal on the bus from a first state to a second state to generate a trigger signal, wherein the sensor is configured to; change the signal from the second state to the first state based on the trigger signal, generate a synchronization signal based on the clock signal and the change of the signal from the second state to the first state, and provide the synchronization signal to the controller via the bus. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A method for establishing a communication between a controller and sensor, comprising:
-
changing, by the controller, a signal from a first state to a second state to generate a trigger signal, the signal being associated with a bus line coupled between the controller and the sensor; changing, by the sensor, the signal from the second state to the first state based on the trigger signal; generating, by the sensor, a clock signal within the sensor; and generating, by the sensor, a synchronization signal based on the clock signal and the changing of the signal from the second state to the first state by the sensor. - View Dependent Claims (15, 16, 17, 18, 19)
