Publication number: 20170067782Abstract: This invention discloses a laser induced breakdown spectroscopy (LIBS) apparatus based on a high repetition rate pulsed laser. The laser produces a train of laser pulses at a high repetition rate in the kHz or even higher range. When the laser beam hits the sample, it generates several thousands of micro-plasma emissions per second. Synchronized miniature CCD array optical spectrometer modules collect the LIBS signal from these micro-plasma emissions. By adjusting the integration time of the spectrometer to cover a plurality of periods of the laser pulse train, the spectrometer integrates the LIBS signal produced by this plurality of laser pulses. Hence the intensity of the obtained LIBS spectrum can be greatly improved to increase the signal-to-noise ratio (SNR) and lower the limit of detection (LOD).Type: ApplicationFiled: May 27, 2016Publication date: March 9, 2017Applicant: BWT Property, Inc.Inventors: Sean Xiaolu Wang, Qun Li

Patent number: 9504847Abstract: An improved method for performing phototherapy. The method comprises a step of applying a supplement to the patient before/after light treatment, which produces nitric oxide in the subject biological tissue to be treated. The nitric oxide serves as signaling molecules to cause vasodilatation and increase blood flow and micro-circulation in the biological tissue so as to enhance the effect and reduce the required treatment time of phototherapy.Type: GrantFiled: December 10, 2010Date of Patent: November 29, 2016Assignee: BWT Property, Inc.Inventors: Brian Pryor, Sean Xiaolu Wang

Patent number: 9370465Abstract: This invention relates to a smart IV bag with a structurally integrated optical tag for IV drug identification and monitoring. The optical tag comprises a flow cell with a fluid channel in communication with the IV bag to sample a portion of the IV fluid onto an optical surface embedded in the flow cell. The optical surface causes a light beam to interact with the sampled IV fluid to produce a spectroscopic signal. The spectroscopic signal is then analyzed to obtain the content and concentration information of the IV fluid. Unlike traditional IV bag labels, the optical tag provides real-time, in-situ monitoring of IV fluid content and concentration, which greatly reduces the risk of mislabeling induced IV error.Type: GrantFiled: October 7, 2013Date of Patent: June 21, 2016Assignee: BWT Property, Inc.Inventor: Sean Xiaolu Wang

Publication number: 20150346103Abstract: This invention discloses a laser induced breakdown spectroscopy (LIBS) apparatus and method for performing spectral imaging of a sample surface. A high repetition rate pulsed laser is employed to produce a train of laser pulses. The laser beam is then scanned by a scanning mechanism over a surface of the subject sample. Each laser pulse produces a LIBS signal from a specific position of the sample surface, which is then measured by a spectrometer device to obtain a LIBS spectrum. The position of the laser beam is recorded and correlated to the corresponding LIBS spectrum. A two dimensional (2-D) mapping of the sample surface to its LIBS spectra is acquired in this manner to construct a LIBS spectral image of the sample surface.Type: ApplicationFiled: May 28, 2015Publication date: December 3, 2015Applicant: BWT Property, Inc.Inventors: Sean Xiaolu Wang, Qun Li
