| 20110169245 | VEHICLE ANTI-THEFT DEVICE - An anti-theft device for a vehicle having a manual brake system to slow or stop the vehicle is provided. The anti-theft device has a locking mechanism connected to the brake housing and can be placed in a locked position and an unlocked position. An interference member connected to the locking mechanism engages the brake actuating mechanism when in the braking position to maintain vehicle braking. In the unlocked position of the locking mechanism, the interference member is disengaged from the brake actuating mechanism to allow uninterrupted operation of the brake actuating mechanism. | 07-14-2011 |

| 20090131802 | Contact sensor for fiberoptic raman probes - The present invention relates to an optical contact sensor for a spectroscopic probe. The sensor detects contact of the distal end of a fiber optic probe to a surface being measured. The system can be used to correct Raman spectral measurements of tissue. | 05-21-2009 |
| 20100069720 | SPECTROSCOPICALLY ENHANCED IMAGING - The present invention provides systems and methods for the spectroscopic determination of the physical characteristics of the tissue under observation by an autofluorescence or other endoscope without the requirement of contacting the tissue directly. The optical probe contained in the endoscope itself is passive and may be either built into the endoscope or positioned in a biopsy channel of same. The spectroscopic information, combined with other information provided by the endoscope such as total fluorescence, improves the sensitivity and specificity of the identification of precancerous or cancerous lesions. | 03-18-2010 |

| 20110213252 | AUTOFLUORESCENCE IMAGING SYSTEM FOR ENDOSCOPY - A system and method for imaging tissue autofluorescence through a video endoscope is described, comprising a light source capable of providing both ultraviolet light capable of inducing tissue autofluorescence and visible light which induces little or no autofluorescence, an optical system to deliver both wavelength bands to the tissue with the same apparent spatial and angular intensity distribution, a means for digitally acquiring the resulting, visible fluorescence and visible reflectance images using a single imaging detector at the distal tip of the endoscope and a means for digitally processing said images to generate a final, false-color image for display which indicates regions of tissue dysplasia. This system can either be added on to an existing video endoscope or integrated into its structure. The combined system can be electronically switched between normal white light imaging and fluorescence imaging. | 09-01-2011 |
