摘要:
Methods for generating physical maps for polynucleotides, such as genomic DNA, are disclosed herein. Also disclosed are methods for identifying the source of polynucleotides. The methods can, for example, be used in physical map construction of whole genome. In addition, methods and systems capable of performing high throughput characterization of macromolecules using nanofludic devices are enclosed.

A polynucleotide is barcoded using a method whereby an isolated, individual polynucleotide is immobilized on a solid phase and stretched, targets are labeled using target-specific hybridization probes, and an individual label of an unamplified probe at each of the labeled targets is optically detected. The order of the labels is determined to form a barcode representation of the polynucleotide wherein the targets and their relative positions are represented.

A computer enclosure includes a chassis with an opening defined therein, an elastic piece, a first drive bracket secured in the chassis, and a second drive bracket. One end of the elastic piece is secured to the chassis adjacent the opening, and the other end of the elastic piece is free and forms a protrusion thereon. The second drive bracket defines a hole therein corresponding to the protrusion. The second drive bracket extends through the opening from an outside of the chassis to pull the protrusion and elastically bend the elastic piece, and then slides on the first drive bracket until the protrusion of the elastic piece is in alignment with the hole of the first drive bracket, the elastic piece rebounds to have the protrusion inserted into the hole to secure the second drive bracket on the first drive bracket.

A mounting apparatus is provided for securing a data storage device. The data storage device has two opposite side walls. Each side wall forms a pair of posts. The mounting apparatus includes a chassis, a bracket mounted in the chassis for accommodating the data storage device, and a latch member pivotally mounted to the bracket. A plurality of slots is defined in one side wall of the bracket for receiving the posts of the data storage device. The latch member includes a base. An elastic arm and a hook extend from the base. The elastic arm resists against the chassis to urge the hook partially covering one of the mounting slots for preventing a corresponding post received in the mounting slot disengaging therefrom. The latch member is being pressable to depress the elastic arm and remove the hook away from the mounting slot thereby release the corresponding post.

A computer enclosure includes a base (10), a cover (30), and a connecting device (40). The connecting device pivotably connects the cover to the base. The connecting device includes a first lever (42), a second lever (44) and a supporting arm (46). The second lever can be stopped by the first lever, for positioning the cover when the cover is in an open position.

A button device includes a base (11) mounted to a bezel (30) of an electronic device. A plurality of button units (17) are disposed in the base (11), and a plurality of through holes (13) are abreast provided in the base (11) in correspondence with the button unit (17). The button unit (17) includes a cap (18) with an elastic member (15) supported thereunder. The elastic member (15) integrally extends from the base (11) and surrounds the through hole (13). A post (19) extends from the inner bottom of the cap (18) and extends through the elastic member (15) and the through hole. In use, the post (19) gets through the hole (13) in the base (11) and touches the switch of the electronic device.

A mounting assembly includes a chassis having a rear wall, a cover slidably mounted to the chassis in a first direction, and a clamping member mounted on the cover. The rear wall has a positioning portion thereon. The clamping member has a cantilever thereon. The cantilever has a locking portion at a free end thereof for engaging with the positioning portion, and a pressing portion at an opposite end thereof for urging the locking portion to disengage from the positioning portion. When the pressing portion of the clamping member is pressed downward in a second direction perpendicular to the first direction, the locking portion is raised, thereby disengaging the locking portion from the positioning portion of the chassis.

The present invention discloses a scented wax heating device, which includes a heating cylinder, an electric wire, and a ceramic heating piece installed at the bottom of the heating cylinder. The heating cylinder is installed in an insulating cylinder for an insulating effect, so that a user can freely move the heating device. The heating cylinder is filled with appropriate amount of water, and the scented wax is put into the heating cylinder. The heating cylinder is heated by the ceramic heating piece, so that the temperature of water in the heating cylinder rises to evenly vaporize the scented wax. The invention features a simple structure and a useful function.
