  • Patent number: 6694159
    Abstract: The present invention relates to a method for wavelength selection in a multi-wavelength TPSF-based optical imaging system. This consists of identifying several chromophores in a highly turbid medium and selecting optimized wavelengths whereby using these wavelengths optimizes the deduction of the chromophore concentrations. Such chromophore concentrations may be combined to deduce other properties of the turbid medium.

  • Patent number: 6659613
    Abstract: Methods, systems, and media relating the display of scattering and/or absorption characteristics of an optical medium. For scattering measurements, a Hartmann-Shack calibration image of a measurement system is acquired to define a first plurality of point spread functions. A Hartmann-Shack test image of the medium is acquired to define a second plurality of point spread functions. A shift is determined between the test image and the calibration image. A point spread of each of the second plurality of point spread functions is measured, each of the second plurality of point spread functions including a component due to optical aberration of the medium and a component due to scatter. The component due to optical aberration is determined using the shift. The component due to optical aberration is deconvolved to determine the component due to scatter. A display of the local scattering characteristics is generated using the component due to scatter.

  • Patent number: 6627879
    Abstract: One illustrative embodiment of a voltage pulser circuit comprises a voltage source producing a first voltage, and a thyratron tube having an anode coupled to the output of the voltage source, a cathode connected to a reference potential and a grid responsive to a grid control voltage to electrically connect the anode to the cathode to thereby cause the first thyratron tube to switch the anode between the first voltage and the reference potential. A pulse-shaping circuit may be connected to the anode of the tube to effectuate desired rise and fall times of the voltage pulses produced by the voltage pulser circuit. Such a voltage pulser circuit is particularly suited for use in connection with the operation of pulsed spectrometer instruments, such as time-of-flight mass spectrometers and the like.

By treating T-cells that have expressed receptor protein H4-1BB with one of the four anti-H4-1BB monoclonal antibodies disclosed herein activation or inhibition of the immune response is seen. Also disclosed herein is cDNA for the human receptor H4-1BB. The cDNA of the human receptor H4-1BB is about 65% homologous to the mouse cDNA 4-1BB and was isolated by using probes derived from murine cDNA 4-1BB.
