摘要:
A spirometry-based device for continuous monitoring of work of breathing (WOB) includes a flow sensor and a respiratory mechanics module connected with the flow sensor. The flow sensor may sample an airway gas flow and an airway pressure when a patient is in a state of inspiration. The respiratory mechanics module may calculate an incremental amount of a gas volume that flows to the patient side in a sampling period, calculate a product of the airway pressure and the incremental amount of the gas volume in the sampling period, and accumulate the product into the WOB.

A method for judging the reverse connection of a flow sensor comprises the steps of: collecting a time sequence of pressure intensity x1, x2, x3 and x4 at four consecutive sampling points of time and the flow value S corresponding to that time sequence as basis for judgment; calculating three variables dx1=x1−x2, dx2=x2−x3 and dx3=x3−x4; judging a reverse connection of the flow sensor and giving an alarm signal when any one of the two instances appears: 1) x1, x2 and x3 are all smaller than zero and x1 and x3 are equal to or greater than x2, and flow value S is smaller than a predetermined first threshold value f1; 2) dx1, dx2 and dx3 are all greater than zero and dx1 and dx3 are smaller than or equal to dx2, and flow value S is greater than a predetermined second threshold value f2.
摘要:
A respiratory mechanics measuring module includes a flow sensor, a differential-pressure sensor and a sampled-signal processing circuit which are connected in series. The module further includes a flow sensor reverse connection judging module and an alarm. The flow sensor reverse connection judging module judges the reverse connection of the flow sensor. The alarm gives an alarm signal indicating the flow sensor reverse connection to the main controller when the flow sensor reverse connection judging module judges that the flow sensor is reversedly connected.

In the present invention, methods and systems for fabricating novel LPFGs are taught. Fabrication is preformed by focusing a CO2 laser beam having a diameter of 30 to 40 μm onto a fiber, such fiber being fixed and weighted on either ends. The variations of transmission spectrum and polarization dependent (PDL) loss of the CO2 laser-grooved LPFGs with different fabrication parameters as functions of applied as functions of applied tensile stain are demonstrated and evaluated.

This invention discloses to a type of fiber gas lasers and fiber ring laser gyroscopes based on these fiber gas lasers. The fiber gas lasers comprise of excitation gases, optical resonator and excitation source, etc. The optical resonator is made by connecting two selected arms of a single mode fiber coupler to the two ends of hollow-core fiber to form a ring resonator. The hollow-core of the fiber is filled with excitation gases to act as gain medium. The fiber laser is simple to construct, lower cost, and has adjustable size and good amplification performance. The fiber ring laser gyroscopes based on this novel type of gas lasers can be applied on robotics, automobile navigation, etc.

摘要:
Described herein is the discovery of novel PSMA-specific peptides, which were identified through a novel combinatorial biopanning method. One of the novel PSMA-specific peptides discovered, GTIQPYPFSWGY (or GTI) (SEQ ID NO: 2), exhibits high binding affinity and selectivity to PSMA and PSMA-positive prostate cancer cells. It was found that GTI can mediate internalization of the apoptotic KLA peptide (SEQ ID NO: 10) to PSMA-positive LNCaP cells and induce cell death. Moreover, a FAM-labeled GTI peptide shows a high and specific tumor uptake in nude mice bearing human prostate cancer xenografts. It was demonstrated that the GTI peptide can be employed as a PSMA-specific ligand for prostate cancer diagnosis and/or for targeted drug delivery to prostate cancer cells.
