Abstract: A surgical hand piece has a source of ultrasonic energy provided to a connecting body having a first passage with one end to receive fluid from a first source and the other end at the connecting body distal end. A work tip has first and second tubes each having at least one opening at its distal end and the proximal end of one or both of the tubes connected to the connecting body distal end to receive the ultrasonic energy and to selectively receive or discharge fluid from either the first or second source as controlled by a valve. A cannula is provided which is adapted to be placed in an opening in the cornea through which the work tip extends during the removal of cataracts from the eye by phacoemulsification. The cannula may be equipped with channels that permit additional infusion of fluid into the eye during the procedure, which infusion also cools the surrounding corneal tissue to protect against heat generated by the ultrasonic vibration of the work tip.

Abstract: A random number generator includes a ring oscillator having an EX-OR gate and four inverters together forming a loop. This loop enters stable state for a start signal having the low level and oscillates for the start signal having the high level. When the start signal has a pulse of a width shorter than the loop's delay time, output nodes responsively, sequentially enter metastable state hovering between the high and low levels. The metastable waveform becomes smaller with time and finally disappears. As metastable state cannot be controlled in longevity, it disappears at any random number node. A counter thus outputs a signal serving as true random number data depending on the longevity of the metastable state. A random number generator miniaturized and having reduced power consumption, and of high performance can thus be implemented.
