1. A method of receiving a cassette to a console of a phacoemulsification system, comprising:
- receiving the cassette into immediate proximity with a cassette receiver comprising a receiving surface;
sensing variations in pressure asserted by the cassette that is received on the receiving surface using detectors mounted diagonally about the receiving surface, wherein each of the detectors senses a change in a respective resistance value in response to the pressure asserted by the cassette on the detectors;
comparing the respective resistance value sensed by each of the detectors with one another using a comparator included within a controller to assess an attitude of the cassette; and
clamping the cassette to the console responsively to said comparing.

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.
