Methods and systems for automatically locating and identifying labware using radio-frequency identification (RFID) tags are described herein. The methods and systems include a plurality of RFID tags (pre-programmed with unique data codes) that are associated with labware (or labware
7191647 Method and apparatus to reject electrical interference in a capacitive liquid level sensor syste March 20, 2007
Methods, systems, and computer program products for measuring a capacitance between a probe and a liquid, pausing movement of the probe based on a rate of change of the capacitance, further measuring the capacitance while the probe is paused, and, based on the further measurements, p
5365783 Capacitive sensing system and technique November 22, 1994
An arrangement senses a liquid level by monitoring the peak capacitance formed between a probe and the liquid as the probe approaches or departs from the liquid. In an automated system, a computer controls the position of a pipette probe for aspirating or dispensing liquid in the vessel.
