摘要:
Devices, systems, and methods for enhancing Raman spectroscopy and hyper-Raman are disclosed. A molecular analysis device for performing Raman spectroscopy comprises a substrate and a laser source disposed on the substrate. The laser source may be configured for emanating a laser radiation, which may irradiate an analyte disposed on a Raman enhancement structure. The Raman enhancement structure may be disposed on the substrate or apart from the substrate. The molecular analysis device also include a radiation receiver disposed on the substrate and configured for receiving a Raman scattered radiation, which may be generated by the irradiation of the analyte and Raman enhancement structure.

An electromagnetic interference (EMI) measuring method and its system for diagnosing EMI of various electronic devices and instructing user to improve design to satisfy Electromagnetic Compatibility (EMC) criterion. The measuring method according to the present invention includes acquiring a set of time domain signal waveforms from a group of uniformly distributed test points on equipment under test (EUT), and then processing, converting, comparing and analysing, and finally determining physical position of EMI on EUT. To implement the present method, the present invention provides an EMI measuring system. The system includes signal acquisition portion and signal analysis portion. The signal analysis portion takes computer as carrier, which establishes processing, converting, comparing and analysing modules on operating system platform of computer. The method steps and system structure according to the present invention are simple and convenient which are no restricted by ambience and the measuring result is reliable.

The present invention concerns a exhaust gas purification system (1), provided with a continuous regeneration-type DPF device (13) having a filter (13b) for collecting PM in exhaust gas (G), provided in an exhaust gas passage (12) of an internal combustion engine (10) provided with an EGR system, for supplying unburned fuel to exhaust gas (G) flowing in the continuous regeneration-type DPF device (13) during the forced regeneration control for regenerating the filter (13b) by forcibly burning PM collected by the filter (13b), characterized by stopping the recirculation of EGR gas (Ge) to the intake passage (14) side in the EGR system, when unburned fuel is supplied to exhaust gas (G) during the forced regeneration control. This prevents the blocking of EGR passage (15) and the sticking of intake valve and so on, caused by the unburned fuel supplied into exhaust gas (G), during the forced regeneration control of the continuous regeneration-type DPF device (13). And this prevents engine troubles caused by these problems.

The present invention generally relates to the field of transcatheter device closure techniques for closing an opening in a tissue and more particularly, to occlusion devices for closing anatomical defects in tissue such as defects consisting of an opening connecting a front side and a back side of a tissue. More particularly the present invention relates to occlusion devices for closing septal abnormalities such as atrial septal defects and patent foramen ovale, delivering systems for such occlusion devices, kits comprising the occlusion devices and the delivering systems and to methods of closing an anatomical defect in a tissue consisting of an opening connecting a front side and a back side of a tissue.
摘要:
The prior auscultation technology is only applicable to the sound signals within the audio range and conducted by vibration. Disclosed in the present invention are a method and an apparatus for auscultating inaudible signals, and thus inaudible signals can be mapped into the audible range to form audible signals. The method comprises: obtaining signal data which comprise audible or inaudible signal data; extracting a signal waveform from the signal data; determining a play rate which allows the signal waveform to phonate by means of an audio play apparatus; and performing the auscultation with the signal waveform being played through the audio play apparatus at the play rate, or combining the play rate and the signal waveform to thereby constitute an audio signal, and then playing the audio signal through the audio player so as to achieve auscultation. When the method and apparatus of the present invention are applied, auscultation can be achieved on any physical parameter changes expressed by wave-shaped curve, which promises to extract information which would have been difficult to find within the inaudible signal in the prior art and promote the development of science and technology innovations.
