Fat depth sensor
First Claim
Patent Images
1. A non-invasive sensor suitable for measuring the depth of fat in tissue, the sensor including:
- microwave signal generation and transmission means adapted to generate and transmit microwave signals into the tissue;
focussing means adapted to focus the microwave signals onto a predetermined focal point;
control means adapted to control the microwave signal generation and transmission means to transmit, in use, at least three discrete narrow band microwave signals into the tissue;
receiving means adapted to receive reflected microwave signals from the tissue and provide magnitude and phase information of the reflected microwave signals; and
processing means for receiving the magnitude and phase information provided by the receiving means and computing a value suitable for identification of the fat depth within the tissue.

Abstract
A non-invasive sensor suitable for measuring the depth of fat in animal tissue is described, the sensor generating and transmitting focussed discrete narrow band microwave signals into the tissue, receiving reflected microwave signals from the tissue and providing magnitude and phase information of the reflected microwave signals for a processor to compute a value of the fat depth within the tissue.
