| 20100062214 | Method for drilling micro-hole and structure thereof - Disclosed is a micro-hole structure and a method for forming the micro-hole. A working energy source is projected onto a predetermined drilling site on a first surface of a substrate for a given period of time so as to melt a portion of the substrate to form a working energy entering section until the working energy source penetrates through a second surface of the substrate to form a micro-hole. A melt formed by melting a portion of the substrate in the micro-hole next to the second surface is allowed to reflow in a direction opposite to the projection of the working energy source to thereby form a reflow section in the substrate. Further, a two or more stages emission of laser pulses is used to form the micro-hole to control the bore diameter of the micro-hole. | 03-11-2010 |
| 20100151560 | Compact disk based platform for separating and detecting immunomagnetic bead labeled cells - Disclosed is a disk based platform for separating and detecting cells that are labeled with immunomagnetic beads. A disk-like carrier board forms therein at least one flow channel structure, which includes an inner reservoir for receiving a sample fluid, an outer reservoir, and a plurality of micro flow channels arranged between and in fluid communication with the inner and outer reservoirs. When the disk-like carrier board spins, cells labeled with immunomagnetic beads are attracted by a magnetic attraction unit that is arranged above the disk-like carrier board and adjacent to the inner reservoir to thereby remain in the inner reservoir, and cells that are not so labeled are acted upon by a centrifugal force induced by the spinning of the disk-like carrier board to flow with the sample fluid from the inner reservoir through the micro flow channels into the outer reservoir. | 06-17-2010 |
| 20100227379 | Compact disk based system for separating immunomagnetic bead labeledparticulates and method thereof - Disclosed is a disk based system for separating at least two types of particulates contained in a sample fluid. The system includes a disk-like carrier board and a magnetic attraction unit. The disk-like carrier board forms at least one flow channel structure, which includes an inner reservoir, at least one separation chamber, and at least one outer reservoir arranged in sequence from a geometric center of the disk-like carrier board to an outer circumferential rim of the disk-like carrier board. A method of separation carried out with the system includes introducing the sample fluid into the inner reservoir and then rotating the disk-like carrier board to induce a centrifugal force. The sample fluid contains particulates that are labeled with immunomagnetic beads and the labeled particulates are attracted by the magnetic force generated by the magnetic attraction unit to retain in the inner reservoir or the separation chamber. Particulates not labeled with the immunomagnetic beads and contained in the sample fluid move with the sample fluid to the outer reservoir. | 09-09-2010 |

| 20090025810 | MICRO-VORTEX GENERATOR - The present invention relates to a MEMS-based micro-oscillator which can generate specific vortical pattern in a micro-channel. The micro-vortex generator is composed of a suspended bridge with a gold-plated, rectangular flat-plate as the primary structure. When an AC current passed through the gold leads under an external magnetic field, the plate will oscillate due to Lorenz force, thereby generating micro-vortices. | 01-29-2009 |
| 20090093376 | Cellular microarray and its microfabrication method - A cellular microarray is disclosed, which has a substrate, multiple first conductive lines, multiple second conductive lines, and multiple PIREs arranged on the surface of the substrate in an array. Each PIRE includes multiple first ring-shaped electrodes, and multiple second ring-shaped electrodes. The first ring-shaped electrodes, and the second ring-shaped electrodes are located on the surface of the substrate alternately in each PIRE. Moreover, the outermost ring-shaped electrodes of any two adjacent feather-shaped electrodes are different. The disclosed cellular microarray can adhere the cells rapidly and uniformly, increase the output of manufacturing, and reduce the cost for manufacturing and application. | 04-09-2009 |
| 20110061472 | BIOCHIP SYSTEM, METHOD FOR DETERMINING SPERM QUALITY AND METHOD FOR SEPARATING SPERM - A method for determining sperm quality is provided. At least one first microfluidic region and at least one second microfluidic region are provided, which meet at a junction. The second microfluidic region includes a shrunk portion with a width sized to substantially allow only one sperm to pass therethrough. A detector is disposed at the shrunk portion. First and second flow fields are formed in the first and second microfluidic regions, respectively. The first and second flow fields have different directions at the junction. A semen sample is loaded at a semen sample loading end. At least one sperm moves in the first microfluidic region against the direction of the first flow field and at least one sperm moves in the second microfluidic region along the direction of the second flow field. The detector generates a signal upon one sperm in the semen sample passing through the shrunk portion. | 03-17-2011 |

| 20100089328 | BIRD FEEDER - A miniature size bird feeder that includes a feed holder; a cap or cover over the feed holder; means for releasably attaching the cap or cover to the feed holder and an attachment means for supporting the feed holder. | 04-15-2010 |
| 20110067635 | BIRD FEEDER - A bird feeder that includes a bird feed holder having open top and bottom ends, a plurality of feeding ports disposed in a sidewall defining the holder, a plurality of perches each associated with an inlet of an associated feeding port and a removable base for engaging with the bottom end of the holder, the removable base having a closed position for sealing the bottom end of the holder so as to retain the bird feed therein and an open position in which the base is removed from the holder to enable access to the bottom end of the holder. One embodiment has a manually operated latch member supported by the base and supported for radial engagement so as to enable releasable securing of the removable base to the holder. In another embodiment a manually operated latch couples to a main body portion, the latch being supported for rotation with respect to the main body portion to releasably secure the base assembly to the housing. Also disclosed is a feeder support apparatus. | 03-24-2011 |
