  • Patent number: 8822928
    Abstract: Reliable and rapid diagnostic methods for many functional syndromes (FS) such as Bladder Pain Syndrome/Interstitial Cystitis (IC) are not available. Exemplary embodiments include rapid and accurate methods for diagnosing FS in humans and other mammals using infrared microspectroscopy (IRMS). Exemplary methods utilize Soft Independent Modeling by Class Analogy (SIMCA) to create classification models. Exemplary methods utilize classification models to categorize a subject's condition (e.g., healthy/sick and or flare/remission). Using these classification models, various embodiments enable diagnosis based on spectra data from a blood sample or other biomedical specimen. Exemplary embodiments may be useful for rapid diagnosis of IC and various other conditions in humans, cats, and/or other mammals.

  • Patent number: 8309931
    Abstract: Reliable and rapid diagnostic methods for many functional syndromes (FS) such as Bladder Pain Syndrome/Interstitial Cystitis (IC) are not available. Exemplary embodiments include rapid and accurate methods for diagnosing FS in humans and domestic cats using infrared microspectroscopy (IRMS). Exemplary methods utilize Soft Independent Modeling by Class Analogy (SIMCA) to create classification models. Exemplary methods utilize classification models to classify a test subject's condition (e.g., healthy/sick). Using these classification models, various embodiments enable diagnosis based on spectra data from a fluid biomedical specimen. Exemplary embodiments may be useful to rapidly diagnose IC and various other conditions in humans, cats, and/or other mammals.

  • Publication number: 20100275856
    Abstract: A clip device that pinch induces a behavior inhibition response in a mammal by means of two jaws that close to form a skin fold loop. The clips device provides manual scruffing by means of gathering skin between the two jaws such that internal surfaces of the skin structure are in juxtaposition to each other and external surfaces of a mammal's skin are at interfaces to the jaws. The clip device is placed on the mammal's neck region or its tail head at a non-noxious pressure between systolic and diastolic blood pressure. The clip device induces a passive response from a mammal so a procedure can be performed on the mammal with two free hands of a user.

  • Publication number: 20050225954
    Abstract: One embodiment of a field changeable graphics system for a computing device includes a graphics card and an interface assembly. The interface assembly is adapted to interface the graphics card with the motherboard of a computing device, without directly mounting the graphics card to the motherboard. One advantage of the disclosed graphics system is that it enables a computing device user to upgrade the existing device's graphics system. Thus, the user is not forced to purchase an entirely new computing device in order to take advantage of graphics innovations. This advantage is particularly significant for users of portable computing devices, such as laptop computers and PDAs.

  • Publication number: 20050227527
    Abstract: One embodiment of an edge connector for a field changeable graphics system includes a right angle edge connector having a plurality of contact pins adapted to engage contacts on a graphics card. The edge connector is adapted to interface the graphics card with the motherboard of a computing device, without directly mounting the graphics card to the motherboard. One advantage of the disclosed edge connector is that it is compatible with a plurality of graphics cards and systems, thereby enabling a computing device user to upgrade the existing device's graphics system. Thus, the user is not forced to purchase an entirely new computing device in order to take advantage of graphics innovations. A further advantage of the disclosed edge connector is that it enables upgrades to low voltage differential signaling (LVDS) features, without the need for additional costly devices capable of operating at LVDS data rates.
