Abstract: A water jets cutting machine includes a first rotating seat driven by a first motor to rotate about a first rotation axis, a second rotating seat driven by a second motor to rotate about a second axis, a water jets cutting head, an inertial measurement unit (IMU) for detecting an inclination angle of the water jets cutting head, and a controller connecting the first and second motors and the IMU. The controller is able to control the first and second motors to instantaneously conduct compensation for angular deviation of the water jets cutting head according to attitude and position signals which are fed back to the controller by the IMU.

Abstract: A microarray biochip workstation allowing positioning of chips, immobilization of molecules, mixing of sample solution, molecular interactions and washing and processing qualitative and quantitative analyses consists of a positioning device for holding a biochip, a mixing device for acting on the sample solution applied on the biochip, a pumping device for removing the sample solution from the biochip surface that does not react, and a reading device for detecting reaction results of the biochip. The workstation thus constructed provides an integrated and effective work interface.

Abstract: A biological cell test method and apparatus employs a conventional perforated cell carrier which has a plurality of holes. Each hole has two metal electrodes. A cell is disposed in the hole to contact the two electrodes. The electrodes are connected to electric current or voltage. The electric current or field flows from one electrode through the cell to another electrode. Through the inherent impedance, inductance or capacitance of the cell, the presence or property reactions of the cell may be detected.
