Patent number: 7691624Abstract: This invention relates to a device for detecting cancer cells. The device includes a light source for generating light (e.g., a light emitting diode), a first optical filter selected from the group consisting of a band pass filter and a long pass filter, a second optical filter (i.e., a band pass filter) disposed between the light source and the first optical filter, and a sample receiver for receiving a sample. The sample receiver is disposed between the first and second optical filters. The first optical filter, the sample receiver, and the second optical filter are aligned so that light emitted from the light source passes sequentially through the second optical filter, the sample receiver, and the first optical filter.Type: GrantFiled: October 18, 2006Date of Patent: April 6, 2010Assignee: Academia SinicaInventors: Ta-Chau Chang, Cheng-Chung Chang, Chi-Chih Kang, Ji-Yen Cheng

Patent number: 7626812Abstract: The present invention relates to a removable hard-disk structure without screws at least comprising a housing, a first elastic arm, a second elastic arm and a removable component. The housing having a placing space is connected to an opening end to enable the hard disk be placed into the placing space, and a door plate is further installed at the opening end to avoid the hard disk departing from the housing. The first and the second elastic arms are installed at the top surface and two side surfaces respectively, and these elastic arms are cantilever type and extend a pressing end into the placing space, which holds and presses the hard disk, and the hard disk is correctly being placed into the placing space. The removable component has a connecting end which is connected into the placing space, as the hard disk is placed in the placing space, the removable component fits the hard disk, and thus the hard disk can be easily removed by applying force on the removable end of the removable component.Type: GrantFiled: January 31, 2008Date of Patent: December 1, 2009Assignee: Sercomm CorporationInventors: Cheng-Chung Chang, Shi-Jun Weng

Publication number: 20090169796Abstract: A large laminated structure includes a surface material, an ink layer, an adhesive layer and a release paper layer. The surface material has a bottom surface. The ink layer is disposed on the bottom surface in a predetermined pattern. The adhesive layer has a first planar surface and a second planar surface corresponding to each other. The adhesive layer has a plurality of channels connecting the first planar surface and the second planar surface. The first planar surface leans against and covers the bottom surface and the ink layer. The release paper layer is connected with the second planar surface. When the adhesive layer is attached to an attaching member, the gas between the adhesive layer and the attaching member may enter the channels of the adhesive layer such that the gas will not be trapped between the adhesive layer and the attaching member, thereby increasing the beauty of the attaching structure.Type: ApplicationFiled: December 26, 2007Publication date: July 2, 2009Applicant: SERCOMM CORPORATIONInventor: Cheng-Chung Chang

Publication number: 20090135561Abstract: An electronic device with airflow field is disclosed, which comprises a housing, several heat sources, a plurality of openings, an air inlet and an air outlet module. By the use of sealed structure of electronic device, the airflow field can be formed inside the housing to direct the airflow for passing through the surface and bottom of each heat source, for the purpose of taking the heat away from the heat sources and promoting the efficiency of heat dissipating greatly. The axial direction of the fan is vertical to the supporting body for forming a sealed space with a local high pressure. It can raise the flow rate and lower the noise of the wind shear from turbulent flow.Type: ApplicationFiled: November 23, 2007Publication date: May 28, 2009Inventors: Cheng-Chung Chang, Shi-Jun Weng

Patent number: 7375959Abstract: An external drive cabinet is provided with, a power connector and a data interface connector installed on the back side of the cabinet frame not on the same level but positioned in step manner, keeping a buffer space in between. Such arrangement of connectors enables one of the two connectors to make connection before the other does, thus smoothing out the plugging and unplugging processes. The tray in the external drive cabinet is equipped with a hinge joint at the rear end that is able to swing the front end of the tray upward when the handle bar of the tray is pulled up. The front panel of the hard disk stored in the drive cabinet can be completely concealed in the drive cabinet.Type: GrantFiled: March 29, 2005Date of Patent: May 20, 2008Assignee: SerComm CorporationInventor: Cheng-Chung Chang

Patent number: 7369408Abstract: A screwless mini fan holder is disclosed. The mount bracket of the fan holder is composed of two clips and four resilient pins projecting from opposite sides of a backplane. The clips are used to couple the fan holder onto the heat sink of a computer. The resilient pins each having a semi-circular ball head are used to attach the mini fan, where one end of each pin is permanently connected to the back side of the backplane, and the other end extends outward at an inclined angle. Such screwless design enables the fan holder without using any mechanical tools. This not only simplifies the assembly of the mini fan in a computer for most computer users, but also allows air flow to be uniformly distributed over the heat sink for maximized heat dissipation.Type: GrantFiled: October 14, 2005Date of Patent: May 6, 2008Assignee: Sercomm CorporationInventor: Cheng-Chung Chang
