US 2006/0069432 A1 · Intraocular lens system

Abstract

A two or three component lens system. The first component is a ring-like supporting component that is implanted in the capsular bag following cataract surgery. The first component is a non-optical component and does not correct for any refractive errors. The first component may contains features to help reduce or eliminate PCO. The second component is an optical component that may contain all of the corrective optical power of the lens system. The second component has a pair of tabs for locking the second component within the first component. The third component is optional and is similar to second component and contains some optical power to correct for any residual optical error not corrected by the second component. The second and third components may also be implanted so as to move relative to one another, thereby providing some accommodation.

Dependent claims

A test device for testing digital semiconductor circuits at wafer level, comprising:

an interposer comprising a printed circuit board with contact pins on both sides, and a needle or contact stud card;
and
a probe card which sends and receives digital test signals to and from a test head and distributes signal channels, carrying test signals, to respective locations on a wafer via the interposer;
wherein all signal channels in the test device or signal channels which carry time-critical test signals in the test device comprise a respective logic signal amplifier mounted on the printed circuit board of the interposer, and wherein each logic signal amplifier amplifies a respective signal received from the wafer or transmitted to the wafer using high and low signal levels.
