摘要:
Provided are methods and systems for identification and analysis of materials and molecular structures. An apparatus for identification and analysis of materials and molecular structures may include a laser. The laser may, in turn, include an amplified spontaneous emission-suppressed single-frequency laser excitation source. The apparatus may further comprise a plurality of filters. The plurality of filters may include reflective volume holographic grating blocking filters. The apparatus may also comprise an optical unit and an optical spectrometer. The optical unit may be configured to deliver excitation energy to a sample substance and capture Raman signal scattering from the sample substance. The optical spectrometer may be disposed in a path of the Raman signal and configured to measure a spectrum of the Raman signal and generate a detection signal. Finally, the apparatus may comprise a processing unit configured to analyze the spectrum.

A transaction record linked to photos taken within geographic or temporal proximity to the various transactions of the record may create a visual way for consumers to interact with their transaction data. Payment transaction data including a customer identifier, a first geo-location of a point-of-sale terminal, and a transaction time stamp may be compared against a second geo-location of a user device associated with the customer identifier. In response to the first geo-location being within a predetermined distance of the second geo-location, an image may be retrieved or created. Transaction records may then show the payment transaction data and the image.

A surround sound system for personal computer includes a control card and a PC surround decoder. The control card is a PC interface card for interfacing to the personal computer and draining the 5 VDC and .+-.12 VDC power from the personal computer as power source for both the control card and the PC surround decoder to operate. The PC surround decoder for processing the stereo source signal and generating left, center, right, surround and subwoofer signals. A connecting means electrically connects the PC surround decoder to the control card. The PC surround sound system is specified for incorporating with personal computer which enables the users to command the PC surround sound system with their computer keyboard or mouse and receive the full benefit of Dolby Surround encoded multimedia software and the like.
