Abstract
Methods and systems are disclosed for employing an ultrasonic sensor to identify a stationary object. The ultrasonic transducer emits an ultrasonic pulse and receives returned signals corresponding to the emitted ultrasonic pulse. The returned signals are evaluated for candidate echoes of a first object. Characteristics of the received returned signals are compared to determine the first candidate echo represents a stationary object.
Claims20
A device comprising:
- an ultrasonic transducer configured to emit an ultrasonic pulse and receive returned signals corresponding to the emitted ultrasonic pulse;
- and
- at least one processor coupled with the ultrasonic transducer and configured to:
- evaluate the returned signals to identify a first candidate echo indicating a first object within range of the ultrasonic transducer;
- identify at least one subsequent candidate echo resulting from a subsequent emitted ultrasonic pulse and a subsequent received returned signal that corresponds to the first object;
- compare characteristics of the received returned signal and the subsequent received returned signal;
- and
- determine the first candidate echo represents a stationary object.
