Claim 11:
12. The system of claim 4 comprising at least non-transitory one machine-readable medium having stored thereon data which, if used by at least one machine, causes the at least one machine to perform operations comprising:
determining a magnitude of a differential pressure present between any two of the first, second, or third voids;
in response to determining the magnitude of the differential pressure, moving at least one of: (a) the first resilient sealing member from an unsealed position to a sealing position by compressing the first resilient sealing member with the first piston, (b) the second resilient sealing member from an unsealed position to a sealing position by compressing the second resilient sealing member with the second piston, or (c) the third resilient sealing member from an unsealed position to a sealing position by compressing the third resilient sealing member with the third piston.
