1. A phacoemulsification system, comprising:
- a cassette comprising positioning surfaces; and
a console comprising;
a cassette receiver configured to couple with the positioning surfaces of the cassette; and
two potentiometers mounted within an area defined by the cassette receiver, wherein the potentiometers are each suitable for depression by a respective one of the positioning surfaces, and wherein incremental changes in an amount of the depressions is indicative of at least one of an alignment and an attitude of said cassette with respect to the cassette receiver; and
wherein the console further comprises a comparator configured to compare, based on an electrical resistance reading, an amount of the depression of one of the potentiometers with that of another of the potentiometers to assess the attitude of the cassette.

Abstract
A system and method of receiving a cassette to a console of a phacoemulsification system. The system and method may include receiving the cassette in close proximity to a cassette receptacle comprising a receiving surface, sensing variations in at least two variable resistances mounted respectively diagonally about the receiving surface, and comparing the variations as between the at least two variable resistances to assess an attitude of the cassette. The system and method may optionally include clamping the cassette responsively to the comparing step.
