Patent Images
1. An apparatus for measuring a body weight of a user, the apparatus comprising:
- a container containing a fluid inside for supporting the user, wherein the container includes a first cell and a second cell, the first cell defines a first opening, the second cell defines a second opening, and the second opening is larger than the first opening for facilitating the fluid contained in the second cell flowing out faster than the fluid contained in the first cell;
a fluid sensor connected to the container, for measuring a physical property of the fluid inside the container; and
a control unit connected to the fluid sensor,wherein the fluid sensor measures a change of the physical property as the user lying on the container, and the control unit determines the body weight of the user based on the change of the physical property.

Abstract
An apparatus and a method for measuring a body weight of a user are provided. The apparatus includes a container containing a fluid inside for supporting the user, a fluid sensor measuring a pressure of the fluid inside the container, and a control unit determining the body weight of the user. The fluid sensor measures a change of the pressure as the user lying on the container, and the control unit determines the body weight of the user based on the change of the pressure.
