摘要： Disclosed is a functional NIRS imaging system including an elastomeric cap, a set of transmit optical fibers and a set of receive optical fibers terminating on the inside surface of the elastomeric cap. A pair of light sources combines to produce a collimated light beam at two wavelengths. An optical modulation system, converts the light beam into a plurality of probe light beams, modulates the plurality of probe light beams with a set of pseudo-orthogonal codes and directs each probe light beam into a transmit fiber. An optical detection system accepts scattered photons from subcutaneous tissue underneath the elastomeric cap as a plurality of collected light beams and converts them into a time series of electronic images, stores the electronic images into the memory and processes the electronic images using the pseudo-orthogonal codes. The system displays the resulting image on a display as a hemoglobin oxygen saturation map.

摘要： A geographical web browser allows a user to navigate a network application such as the Word Wide Web by physically navigating in geographical coordinates. For example, a geographical web browser is implemented in a mobile unit such as a dashboard computer. The mobile unit includes one or more transducers such as antennas and is operative to receive locally broadcast signals or to operate a global positioning system (GPS) receiver. As the mobile unit navigates into different physical localities, different web pages are displayed by the geographical web browser. For example, a user desiring to buy a house can set the web browser to a real estate web page. Instead of clicking on a hyperlink to access web pages of properties in an area, the user drives into a first area and automatically receives web pages relating to homes in that area. When the mobile unit crosses town and enters a second area, a new set of web pages is downloaded relating to properties in the second area. The geographical web browser, methods, apparatus and systems disclosed herein enable improved road-navigation and traffic management, advertisement, and related services.

摘要： A geographical web browser allows a user to navigate a network application such as the Word Wide Web by physically navigating in geographical coordinates and roaming through coverage areas of cellular base stations, wireless LANs, microcells, and other such broadcast domains. A mobile unit communicates with a network server via an air interface that supports wireless packet data. A network server uses a set of user preferences to filter a set of server-side information in accordance with a user's interest. A content-selective information filter performs a network server-side search to identify content that matches the user's preferences and automatically downloads the information to the mobile unit based on a geographic event.

摘要： The present invention relates, in general, to the field of motion tracking, and in particular to join a target in an MRI application. In particular the invention teaches an apparatus and method to track the movement of a target during medical imaging scanning using optical technology. Optical systems record the position and movement of the pattern and are able to perform mathematical analysis of the pattern to determine the positional shift of the patient. Weighted averages, Fourier transforms, Hadamard matrices and cross-correlation of data related to X-Y translation, rotation and scaling of the image of the pattern are used to analyze movement of the subject's head. Feedback related to the movement is provided to the MRI machine which allows for adjustments in focusing coils for real time tracking of the patient's movements during the MRI procedure. As a result, the MRI procedure becomes more accurate as it is adjusted for the patient's movements.

摘要： An optically-based rigid-body 6-DOF motion tracking system optimized for prospective (real-time) motion correction in Magnetic Resonance Imaging (MRI) applications using a single camera with an on-board image processor, an IR illuminator and optical fiducial targets affixed to a patient. An angle extraction algorithm operated by the on-board image processor utilizes successive approximation to solve the 3-point pose problem for angles close to the origin to achieve convergence to sub-microradian levels. A motion alarm is enabled by a monitor and GUI application in communication with the motion tracking system. A motion correction is enabled for MR scan images taken while operating the motion tracking system wherein an MRI controller is in communication with the motion tracking system.
