  • Publication number: 20070142727
    Abstract: A cardiovascular pressure data analyzing system having one or more implanted pressure sensors, an implanted communication device in wireless communication with the sensor and an external data processing unit adapted to use real-time barometric data to calibrate uncalibrated pressure data received from the communication device. The external data processing unit can be portable, is in communication with a remote database to transfer the calibrated pressure data to the remote database, and is capable of providing reprogramming information to the communication device. A method of analyzing pressure data including gathering pressure data from an implanted pressure sensor in a human body, retrieving the pressure data through a communication device implanted in the human body, transmitting pressure data from the communication device to an external data processing unit, and calibrating the pressure data at the external processing unit to compensate for inherent characteristics of the sensor.

  • Publication number: 20070009207
    Abstract: An optical delay line for use with an optical source including input/output optics optically coupled to the optical source and a curved mirror with a reflective surface that is centered about an evolute curve of the delay line to retro-reflect light traveling along a delay line beam path tangent to the edge of the evolute curve. The input/output optics direct light from the optical source along the delay line beam path and direct delayed light from the delay line beam path out of the optical delay line along an output beam path. The input/output optics and/or the curved mirror rotate about the evolute curve at a selected angular speed. The reflective surface has a curvature based on a parametric curve that is calculated from the evolute curve such that the delay of the delay line varies according to a predetermined function as the input/output optics and/or the curved mirror rotate.

  • Patent number: 7139799
    Abstract: A group-browsing system for a plurality of clients each including a shared web browser. A server is linked to the shared web browser of each client and is configured to monitor the transmission of the web site URL request from the shared web browser of one client of the group and to direct the request to the shared web browser of other clients in the group. A gatekeeper module is configured to first mask the identity of each client's computer on the shared browser. This prevents the web site from retrieving any client's actual identifier. Second, the gatekeeper is also configured to create a same temporary identifier for each client when any client logs on to the web site so that the same web page is displayed for all the clients in the group.

  • Publication number: 20060214114
    Abstract: A broad bandwidth detector to measure intensity information of terahertz (THz) frequency pulses. The detector includes: coupling optics coupled to a coherent optical source; a GaSe substrate aligned such that the probe beam path intersects a first surface at a phase-matching angle; a polarization detector aligned in the probe beam path; and calculation means coupled to the polarization detector. The coupling optics direct the probe optical beam along a beam path that is substantially collinear with the pulse beam path of the THz frequency pulses. The polarization of the probe optical beam is varied based on interactions between the probe optical beam and the THz frequency pulses within the GaSe substrate. The polarization detector detects the varied polarization of the probe optical beam. The calculation means determine the intensity information of the THz frequency pulses based on the detected probe polarization of the probe optical beam.

  • Patent number: 7091506
    Abstract: An apparatus and a method for the generation of high-energy terahertz radiation. The apparatus and method function by impinging optical radiation on the surface of a semiconductor substrate, creating a photo-generated dipole emitting terahertz radiation. Because it is desirable to orient the dipole perpendicular to the radiation direction to maximize the power of the terahertz radiation, the surface of the semiconductor is modified to achieve this desirable result. More specifically, three embodiments of the surface modification are disclosed: (1) a grating is created in the top surface of a GaAs semiconductor substrate, (2) an InAs film is formed on a Teflon base to create a grating structure on the semiconductor substrate, and (3) a grating is disposed in the surface of the semiconductor substrate such that the optical radiation engages the substrate at Brewster's angle.
