  • Publication number: 20190246900
    Abstract: This present invention comprises a Galilean tele-microscope lens assembly configured to attach to the front of a binocular indirect ophthalmoscope (BIO) either permanently or by means of a clip or other suitable detachable mechanism, and to enhance an image of a patient's ocular fundus produced by a condensing lens hand-held by the examiner, at their arm's length, in front of the patient's eye. The lens assembly of the present invention magnifies the examiner's view of the hand-held condensing lens itself, and thus magnifies the fundus image produced by the hand-held condensing lens, enabling improved appreciation of finer details in an examination. In addition to improving BIO examinations in general, the present invention is especially advantageous for patients who have disabilities, are wheelchair bound, are children, or are patients of “mission” based ophthalmoscopy services provided in developing, “emerging economy” countries where other examination equipment may not be available.

  • Patent number: 10193176
    Abstract: The disclosure provides a system and method for synthesizing ultra-pure hydrogen from biomass waste. The present invention comprises a gasifier, an oils and tars filter, a steam generator, a water gas shift reactor (“WGS”), a heat-exchange two-phase water separator, a scrubber, a hydrogen separator, and fluid conduits in fluid communication with the various system components, which together convert hydrocarbon-based biomass, e.g., woodchips, into ultra-pure hydrogen gas. Fluid conduits connect the gasifier and the steam generator, separately, to the WGS, the WGS to the two-phase separator, the two-phase separator to the scrubber, and the scrubber to the hydrogen separator, which further comprises an outlet port through which hydrogen gas may flow free of carbon monoxide. The hydrogen may flow to a device that utilizes hydrogen to generate energy, such as a hydrogen fuel cell or to an internal combustion engine.

  • Publication number: 20180287262
    Abstract: Orbital angular momentum (OAM) communications systems provide an additional degree of freedom to the electromagnetic waves that travel between the transmission and receiving stations, thereby enabling a dramatic increase in data transmission rates. The present invention provides a design for a very low reflectivity flat spiral phase plate that generates OAM modes and a method of making the same. The design incorporates variable sizes of perforated unit cells and may include matched layers to provide improved impedance matching, and the flat disc shape makes the phase plate compact and easy to install. The OAM phase plate can be designed to operate at frequencies from a few 100s KHz to ultraviolet frequencies and is capable of providing one or more OAM modes at the operational frequencies, irrespective of polarization. In a preferred embodiment, the OAM phase plate is designed for operation at about 30 GHz frequency, with 20 GHz bandwidth.

  • Patent number: 8198432
    Abstract: This invention describes a first report on the synthesis of certain 124I-labelled photosensitizers related to chlorines and bacteriochlorins with long wavelength absorption in the range of 660-800 nm. In preliminary studies, these compounds show a great potential for tumor detection by positron emission tomography (PET) and treatment by photodynamic therapy (PDT). The development of tumor imaging or improved photodynamic therapy agent(s) itself represent an important step, but a dual function agent (PET imaging and PDT) provides the potential for diagnostic body scan followed by targeted therapy.

  • Publication number: 20090055437
    Abstract: Management of information is facilitated by unambiguously tracking portions of reality over time. To track the portions of reality, a referent tracking system is used. The referent tracking system is able to communicate with other tracking systems and/or tradition information systems. Errors in the referent tracking system are detected and corrected to maintain actual representations of the portions of reality.

  • Patent number: 7398321
    Abstract: This invention broadly comprises a novel segment protection scheme (survivability framework) for a network, which we refer to as PROMISE (Protection using MultIple SEgments). It combines the best of existing link and path protection schemes (e.g., bandwidth efficiency and fast recovery). The PROMISE approach divides an active path or AP (along which a survivable connection is established) into several, possibly overlapping active segments or ASs, and then protects each AS with a detour called backup segment or BS (instead of protecting the AP as a whole as in path protection schemes). This facilitates the bandwidth sharing not only among the BSs for different APs, but also among those for the same AP. In addition, recovery time can be shortened due to the limited length of each AS and BS. This technology can be applied to MPLS, ATM, SONET, WDM and other high-speed link layers under the evolving G-MPLS framework.

  • Patent number: 7239717
    Abstract: Current methods of embedding hidden data in an image inevitably distort the original image by noise. This distortion cannot generally be removed completely because of quantization, bit-replacement, or truncation at the grayscales 0 and 255. The distortion, though often small, may make the original image unacceptable for medical applications, or for military and law enforcement applications where an image must be inspected under unusual viewing conditions (e.g., after filtering or extreme zoom). The present invention provides high-capacity embedding of data that is lossless (or distortion-free) because, after embedded information is extracted from a cover image, we revert to an exact copy of the original image before the embedding took place. This new technique is a powerful tool for a variety of tasks, including lossless robust watermarking, lossless authentication with fragile watermarks, and steganalysis. The technique is applicable to raw, uncompressed formats (e.g., BMP, PCX, PGM, RAS, etc.

  • Patent number: 6882997
    Abstract: The method termed WaveCluster for mining spatial data. WaveCluster considers spatial data as a multidimensional signals and applies wavelet transforms, a signal-processing technique, to convert the spatial data into the frequency domain. The wavelet transforms produce a transformed space where natural clusters in the data become more distinguishable. The method quantizes a feature space to determine cells of the feature space, assigns objects to the cells, applies a wavelet transform on the quantized feature space to obtain a transformed feature space, finds connected clusters in sub bands at different levels of the transformed feature space, assigns labels to the cells, creates a look-up table, and maps the objects to the clusters. The method can manage spatial data in a two-dimensional feature space. The method also is applicable to a feature space that is made up of an image taken by a satellite.

  • Patent number: RE40477
    Abstract: A system and method that efficiently, accurately, and simply detect reliably least-significant-bit (“LSB”) embedding of a secret message in randomly scattered pixels. The system and method apply to both 24-bit color images and 8-bit grayscale or color images. Many commercial steganographic programs use Least Significant Bit embedding (LSB) as the method of choice to hide messages in 24-bit, 8-bit color images and in grayscale images. They do so based on the common belief that changes to the LSBs of colors cannot be detected because of noise that is always present in digital images. By inspecting the differences in capacity for lossless (invertible) embedding in the LSB and the shifted LSB plane, the present invention reliably detects messages as short as 1% of the total number of pixels (assuming 1 bit per sample). The system and method of the present invention are fast, and they provide accurate estimates for the length of the embedded secret message.
