First Claim
Patent Images
1. A method of detecting the displacement of a target in a given environment, comprising:
- storing reference data comprising data representative of the environment;
transmitting a transmit signal towards the target;
sensing the return signals from the target and the environment; and
detecting the displacement of the target by comparing the return signals and the reference data;
the reference data being updated at an update rate which is varied in dependence on the displacement of the target.

Abstract
A method of detecting the displacement of a target in a given environment includes storing reference data having data representative of the environment; transmitting a transmit signal towards the target; sensing the return signals from the target and the environment; and detecting the displacement of the target by comparing the return signals and the stored reference data. A method of detecting the level of a sample in a container is also disclosed. Analogous apparatus features are also disclosed.
