reference volume of a luggage compartment

A reference volume (21) is provided for compensating for temperature.

For each signal class there may be corresponding reference volume data.

To set the desired reference pressure in the reference pressure chamber (19) of the pressure switch, the reference volume filled with gas, and thereby the reference pressure (36, 39), can be permanently modified.

To adjust a specified oxygen concentration in the reference volume, the power source is operated in a regeneration operating state (RGBZ), specifically, an adjustment of the oxygen concentration in the reference air volume.

The method relies on an image-based technique that transforms a target volume to align with a reference volume.

The reference electrode (36) has an associated pump reference volume (58) with a coating (60) with a high gas diffusion resistance.

The pump also includes a reference-volume assembly and/or a linear position sensor.

The first volume level is adjusted based on at least information associated with the first comparison result and a reference volume level.

The volume of liquid in the chamber may then be measured based on (a) the initial pressure, (b) the final pressure, (c) the reference volume and (d) the volume of the subject chamber.

A pressure which is a function of the highest pressure level communicated to the reservoir is trapped in the reference volume.

The final pressure of the control gas is also measured after the reference volume has been removed from or added to the chamber and while the volume of control gas remains otherwise isolated.

The reference-volume assembly and/or linear position sensor may be used to estimate the amount of liquid discharged from the reservoir.

The excitation source generates a pressure pulse within the reference volume to influence generation of the pressure sensor signal.

This is a solid reference volume that belongs in every serious seeker's private collection.
