Abstract: In the field of trace organic matter detection, a substrate holder for mass production of surface-enhanced Raman scattering (SERS) substrates includes a ring-shaped body and a support frame thereof. A plurality of cones are disposed on the ring-shaped body, and a plurality of substrates are pasted on both surfaces of each cone. The substrate holder allows for simultaneous deposition of silver nanorods on a plurality of substrates by glancing angle deposition method. An array film composed of the silver nanorods of a plurality of substrates has good product homogeneity, and the production efficiency of a traditional preparation method can be improved.

Abstract: Disclosed are a flexible paper-based surface-enhanced Raman scattering (SERS) substrate and a method of preparing the same, which relate to detection of trace organics. This invention deposits a film of silver nanoparticles on a carrier such as filter paper by oblique-angle deposition to prepare the SERS substrate, which can be used for the detection of trace organics. Silver nanoparticles are closely arranged on the flexible paper, allowing the substrate for good SERS effect due to the interparticle coupling effect. Moreover, compared to the traditional rigid and brittle substrates, the substrate prepared herein can be readily used in the detection of residual organics on complex surfaces in various liquid or solid conditions by dipping, dropwise adding or wiping due to the use of a flexible and absorbent carrier.

Abstract: A verification apparatus that verifies whether a reference circuit and an implemented circuit are logically equivalent deletes, respectively therefrom, all buffers and an even number of inverters between flip-flops. On each of the circuits, the apparatus further deletes and merges a flip-flop to another flip-flop that is logically equivalent. The name of the deleted flip-flip is added to the name of the flip-flop to which it is merged. The apparatus compares all of the names of the flip-flops and pairs the flip-flops by name. From the input pin of each of the paired flip-flops, logic cones are defined and using these logic cones, comparison of and verification between the reference circuit and the implemented circuit is performed.

Abstract: The present invention discloses an Advertisement Platform (ADP), including an ADP Switch Point (ADP-SP), a voice playing unit and a service logic supporting unit; wherein the ADP-SP connects a call from a calling LS or an MS and initiates an advertisement service call to the service logic supporting unit; upon receiving the advertisement service call from the ADP-SP, the service logic supporting unit returns advertisement service instruction to the ADP-SP after parsing the advertisement service call; upon receiving the advertisement service instruction returned by the service logic supporting unit, the ADP-SP instructs the voice playing unit to play a ring back tone which includes advertisement according to the advertisement service instruction and connects a voice channel used for the voice playing unit playing advertisement with the calling voice channel or the MS voice channel. The present invention also discloses a system and method for playing advertisement.
