摘要： The present invention provides a surface plasmon resonance (SPR) unit having at least one microfluidic channel with grating structures embedded in so that a grating-coupled surface plasmon resonance can be induced by an incident light while fluid in the microfluidic channel contacts or flows through the grating area. The induced variation of optical signal due to the SPR effect is analyzed for performing bio-screening and assay of bioaffinity reaction. Meanwhile, present invention further provides an SPR inspection system possessing a rotation power to the SPR unit such that the SPR unit is capable of rotating and thereby generating a centrifugal force for driving the flow inside the microfluidic channels so as to achieve the label-free and high throughput SPR inspection system with low-cost.

摘要： A sensorless driving method for a brushless DC motor is provided. The time for the motor to rotate an electrical angle 60° is obtained by alternatively counting the occurrences of zero crossings with two counters and comparing the counted values, and the motor is delayed an electrical angle of 30°, by which a precise commutating time is obtained. The driving method provides a mask-based phase shift digital detection mechanism for effectively detecting true zero-crossing points. The driving method further provides an inhabitation mechanism with the function of soft-switch for inhibiting noise caused by transistor switching. By using these two counters, the time for the motor to rotate two electrical angles 30°−Δθ and 30°+Δθ are obtained and stored in two registers. The time period before and after the commutating point is added into a pulse width modulation (PWM) signal to reduce the noise and vibration.

摘要： The present invention provides a tuning mechanism for flying pickup heads in data storage devices. The pickup device includes a coil, a pivot, a suspension, and a piezoelectric bender. The piezoelectric bender made by a bi-layer or a multi-layer piezoelectric material is formed on one end of the suspension, and proper voltages applied to the piezoelectric bender via wires enable the piezoelectric bender to undergo both neutral axis displacement and bending deflection. A pickup head is attached to the free end of the piezoelectric bender opposite to the coil, and via the piezoelectric bender, focusing and tracking motion of the pickup head can be tuned at the same time. Furthermore, since the characteristic of the piezoelectric bender is similar to bimetallic elements, the bender can undergo large bending deflection to compensate large deformation of rotating optical disks, so that the flying height of the pickup head can be tuned to maintain a constant focusing distance in reading/writing data.
