  • Method, system and apparatus for incorporating capacitive proximity sensing in an automated fluid transfer procedure
    Patent number: 9046507
    Abstract: A fluid transfer apparatus includes a fluid transfer probe, a fluid level detection system, and a tip detection system. The fluid level detection system is configured to detect contact by the fluid transfer probe with a fluid surface within a receptacle from a signal based on the capacitance of the fluid transfer probe. The tip detection system is configured to detect the presence or absence of a tip at a distal end of the fluid transfer probe from a signal based on the capacitance of the fluid transfer probe.
