  • Publication number: 20210335086
    Abstract: Gaming devices, systems, and methods include a gaming device that includes a display device and an image capture device to capture a plurality of images of an eye of a player of the gaming device at a plurality of respective times. The gaming device generates, for each image of the plurality of images, gaze direction data indicative of a gaze direction of the eye of the player at the respective time corresponding to the image. The gaming device accesses a player database including player data for a plurality of players, the player data including, for each player, stored gaze data. Based on the gaze direction data and the stored gaze data, the gaming device determines a player parameter value corresponding to a player parameter for the player. Based on the player parameter value, the gaming device modifies a game feature of a wagering game at the gaming device.

  • Patent number: 8245198
    Abstract: The present invention extends to methods, systems, and computer program products for mapping breakpoints between Web based documents. Embodiments of the invention facilitate extracting corresponding client script blocks from different Web based documents to disassociate the client script blocks with their relative locations within the Web based documents. From the extracted client side script blocks, a position for mapping a breakpoint from one client side script block another client side script block can be determined. The breakpoint is then copied from the one client script block and inserted into the determined position in the other client script block. The client script blocks can then be re-associated with their relative locations in the Web based documents from which they were extracted.

  • Patent number: 7144485
    Abstract: This invention relates to a strip for analyzing a sample. The strip includes two insulating layers, a spacer layer, and a conducting circuit. The spacer layer is disposed between the two insulating layers, and configured to define, together with the two insulating layers, an adsorption port, a sample chamber, a capillary for delivering a sample from the adsorption port to the sample chamber through the capillary, and a vent for facilitating delivery of the sample into the sample chamber. The conducting circuit, also disposed between the two insulating layers, includes a working electrode, a counter electrode, conducting wires, and connectors. A test agent, reactive to an analyte in a sample, is in association with the electrodes.

  • Patent number: 5405957
    Abstract: A group of novel expanded porphyrin-like compounds, porphacyanine (Pc) and porphacyanine-like compounds, having absorption maxima in the range of 400-850 nanometers is useful in detecting and treating targeted tissues, cells and viruses. The use of the Pc of the invention permits the irradiation to comprise wavelengths other than those absorbed by blood. The Pc of the invention may also be conjugated to target-specific moieties such as immunoglobulins or fragments thereof to target specific tissues or cells for the radiation treatment. Use of these materials permits greater depth of treatment penetration and greater specificity in targeting tissues or cells. Coupled with an appropriate paramagnetic ion or radioisotope, the Pc of the invention is suitable for use in nuclear magnetic resonance imaging and radioimaging.
