  • Patent number: 7227145
    Abstract: A photodetector for detecting the polarization or wavelength of incident infrared radiation (IR) is described. The polarization sensitive photodetector operates using two sets of patches and corresponding cavities, the first set resonating with IR having a first polarization, while the second set resonates with IR having an orthogonal, second polarization. The polarization sensitive photodetector thus outputs two signals, proportional to the first and second polarizations, respectively. The wavelength sensitive photodetector operates using two sets of patches and corresponding cavities, the first set resonating at a first IR wavelength, while the second set resonates at a different IR wavelength. The wavelength sensitive photodetector thus outputs two signals, proportional to the first and second wavelengths, respectively. The patches have a length corresponding to odd multiples of the effective wavelength of the IR, while the thickness of the photodetector is typically one fourth of the effective wavelength.

  • Patent number: 7214195
    Abstract: A method of and apparatus for detecting diseased tissue based upon infrared imaging in two different bands of infrared wavelengths is described. The use of two series of infrared images taken in two different bands of infrared wavelengths increases sensitivity to the subtle temperature changes caused by diseased skin and tissue, especially in the case of cancerous tissue. By sensing skin temperature, the homogeneity thereof, the time variations thereof and the correlation between the two series of infrared images, the present invention decreases the rate of false positives and false negatives. The increased discrimination due to two series of infrared images allows for reliable detection of diseased or cancerous tissue even in the presence of skin tone variations such as birthmarks, tattoos and freckles. The present invention finds special application in the field of breast cancer detection where subtle skin temperature variations may readily be sensed using two series of infrared images.

  • Patent number: 7138631
    Abstract: A photodetector for detecting infrared radiation (IR) using a slab waveguide is described. The slab waveguide photodetector operates by resonating transverse magnetic or electric modes within the slab from the incident IR. An IR absorbing layer is located within the slab waveguide photodetector where the magnitude of the electric field vector is greatest. This permits the use of a thinner IR absorbing layer without sacrificing photoresponse. Multi-color slab waveguide photodetectors are permitted because multiple transverse magnetic or electric modes resonate within the slab waveguide. A reflective or transmissive grating is used to launch the IR into the IR absorbing layer through a cladding or antireflection layer.

  • Patent number: 7135698
    Abstract: A multi-spectral super-pixel photodetector for detecting four or more different bands of infrared radiation is described. The super-pixel photodetector includes two or more sub-pixel photodetectors, each of which includes a diffractive resonant optical cavity that resonates at two or more infrared radiation bands of interest. By detecting infrared radiation at two or more different applied biases and by generating a spectral response curve for each of the sub-pixel photodetectors at each of these biases, the response to each of the individual bands of infrared radiation can be calculated. The response to each band of infrared radiation can be found by deconvolving the response at each bias. The super-pixel photodetector finds use in military and medical imaging applications and can cover a broad portion of the infrared spectrum.

  • Patent number: 7127416
    Abstract: An electronic commerce system (10) includes a server (40) operating on one or more computers that communicates a search query for one or more products to one or more seller databases (32) that contain product data. Each seller database (32) generates local search results that are responsive to the search query. The server (40) also communicates one or more sorting parameters to the seller databases (32). The sorting parameters direct each seller database (32) to sort local search results generated at each seller database (32) according to the sorting parameters in response to the search query. In addition, the server (40) receives sorted local search results from one or more of the seller databases (32) and merges the sorted local search results received from the seller databases (32) to generate merged search results. Furthermore, the server (40) sorts the merged search results according to the sorting parameters and communicates the sorted merged search results to a user.
