Abstract: A method for detecting cancer includes providing a biomedical sample, performing a first adsorption step, performing a first desorption step, and performing a first discrimination step. The first adsorbing step includes immersing the biomedical sample into a first detection reagent having a first adsorbent that adsorbs onto the biomedical sample. The first desorption step includes immersing the biomedical sample into a first desorbing agent for a first period of time. The first discrimination step includes measuring an amount residual of first adsorbent adsorbed on the biomedical sample for identifying distribution of cancer cells within the biomedical sample. The present invention could be widely applied for detecting various cancers based on the differential physisorption of adsorbent. The present invention can provide a method for rapidly and non-invasively detecting cancers.

Abstract: An annulus illuminator of microscope is provided. The collimated light pipe produced by a pair of convex and concave cone mirrors of this illuminator provides illumination of darkfield microscopy. Sliding the convex cone mirror along the coaxial track of the cone mirror pair may continuously change the diameter of the collimated light pipe. Furthermore, this invention provides illumination of brightfield microscopy. A 45° rod-mirror is directly attached to the extension rod of the convex cone mirror for transmitting light from the same or an alternative light source of the microscope. Therefore, the present invention provides with dual-illumination function for both brightfield and darkfield microscopy and may be conveniently adapted to commercial microscopes.

Abstract: A memory apparatus and method for protecting the memory apparatus are provided. The memory apparatus includes a memory unit, a memory control unit, a switch and a control circuit. The memory control unit is used for reading from or writing to the memory unit and has a build-in protection unit. The switch has a lock end and a normal end. The control circuit is coupled between the switch and the memory control unit and is used for detecting the position of the switch. Once the switch is switched to the lock end and the memory apparatus receives a working voltage, the protection unit is automatically enabled by the control circuit to inhibit the memory control unit from reading data from or writing data to the memory unit.
