Title: High-precision air pressure positioning method using piezoelectric actuator

IPC: G05B19/402
Filed: 2003-08-08
Abstract: The present invention relates to a high-precision air pressure positioning method using piezoelectric actuator, which isprovided to improve an air pressure driving system. An impact force generation mechanism formed by mounting a piezoelectric actuator on a conventional air pressure driving device. The pressure difference between two inlet/outlet holes of an air pressure cylinder is controlled so that the net force generated by the air pressure difference and exerted on the piston ring is smaller than the friction force applied on a push rod or a moveable platen to be driven. Then, an impact force generated by instantaneously expanding and contracting a voltage waveform of the piezoelectric actuator is applied to drive and slightly move the push rod or the moveable, thereby generating precise steps in micrometer/nanometer scale. In addition to having the advantages high speed, large stroke, cleanliness and safety provided by the conventional air pressure system, the present invention also possesses precise positioning capability in micrometer/nanometer scale.

Patent TW-200419579-A (TW)
Title: Non-volatile memory and method with improved sensing
Inventor: CERNEA RAUL-ADRIAN
IPC: G11C29/02
Filed: 2003-09-24
Abstract: Source line bias is an error introduced by a non-zero resistance in the ground loop of the read/write circuits. During sensing the control gate voltage of a memory cell is erroneously biased by a voltage drop across the resistance. This error is minimized when the current flowing through the ground loop is reduced. A method for reducing source line bias is accomplished by read/write circuits with features and techniques for multi-pass sensing. When a page of memory cells are being sensed in parallel, each pass helps to identify and shut down the memory cells with conduction current higher than a given demarcation current value. In particular, the identified memory cells are shut down after all sensing in the current pass have been completed. In this way the shutting down operation does not disturb the sensing operation. Sensing in subsequent passes will be less affected by source line bias since the total amount of current flow is significantly reduced by eliminating contributions from the higher current cells. In another aspect of sensing improvement, a reference sense amplifier is employed to control multiple sense amplifiers to reduce their dependence on power supply and environmental variations.
