A pressure relief device for venting an internally pressurized container such as an aerosol can has three sections, a concave annular outer area, a circular central area and an annular intermediate area connecting the concave annular area to the circular area. An ARS may provide hypotheses of the 3D configuration of body parts or the entire body from a single depth frame. Next, the other component is placed in the well above the first placed component. Transmitter circuitry provides a transmitter output based upon the output from the differential pressure sensor and further provides enhanced functionality based upon the output from the first pressure sensor.
