| 20080306365 | DECEPTION DETECTION AND QUERY METHODOLOGY FOR DETERMINING DECEPTION VIA NEUROIMAGING - Functional near-infrared (fNIR) neuroimaging is used to assess credibility, detect deception, and implement a query methodology for determining deception via neuroimaging. Oxygenation levels of portions of the brain are imaged via fNIR spectroscopy and utilized to determine if the subject is telling a lie or a truth. In an example configuration, oxygenation levels in the inferior and/or middle prefrontal cortical areas of the brain, such as the bilateral dorsolateral prefrontal and/or inferior frontal cortex, are measured to determine if a subject is lying relative to telling the truth. An example system includes a portable, flexible, belt like sensing device that is positioned proximate the subjects scalp. Sensed neural activity is transmitted either through wired or wireless means, to a processor for analysis of the sensed neural activity. The query methodology utilizes an attestation assertion that mitigates variance in brain responses due to the length or form of a question. | 12-11-2008 |

| 20100208270 | Low-cost, portable, rugged optical coherence tomography system - An interferometric system for metrology as well as imaging (e.g., optical coherence tomography or OCT) is described here. The system leverages advancements in telecommunication and device technologies. For example, the reference arm in the interferometric system can be a fiber-optically integrated Faraday rotating mirror. By way of example, but not limitation, typically, the light in the detection arm of the Michelson interferometer can be measured using a Volume phase holographic dispersion grating. By way of example, but not limitation, the dispersed light can be focused on a line-scan camera or multi-line 2-D camera. | 08-19-2010 |
| 20100245836 | Low-cost, compact, & automated diabetic retinopathy diagnostics & management device - A Diabetic Retinopathy Diagnostic system based on OCT which will map 3-D blood circulation including velocity information with micron-scale resolution in the retina is disclosed here. The system leverages the advancements in telecommunication and device technologies and employs novel Doppler algorithms. For example, the reference arm in the interferometric system can be a fiber-optically integrated Faraday rotating mirror. By way of example, but not limitation, typically, the light in the detection arm of the Michelson interferometer can be measured using a Volume phase holographic dispersion grating. By way of example, but not limitation, the dispersed light can be focused on a line-scan camera or multi-line 2-D camera. | 09-30-2010 |

| 20090231285 | INTERPRETING AMBIGUOUS INPUTS ON A TOUCH-SCREEN - A method for interpreting ambiguous click events in relation to click targets on a touch-screen display disposed at respective click target locations includes detecting a touch at a touch location and determining whether the touch location corresponds to a click target location. The method also includes searching for nearby click target locations in a predetermined click region and, upon locating a first click target location within the predetermined click region, associating the touch with the first click target location to identify a click event. A computing device for facilitating accurate touch input targeting with respect to a touch-screen display includes a display component, a touch detection component, a targeting component that associates a touch with a click target, and an event detection component that associates the touch with one of a right click event, a left click event, or a drag event. | 09-17-2009 |
| 20090322687 | VIRTUAL TOUCHPAD - Embodiments described herein are directed to simultaneously presenting a virtual touchpad and a graphical user interface of an operating system on the same display. A user can interact with the OS using the virtual touchpad, and user touches are read by a touch-screen portion of the display assigned to the touchpad. Touch input software converts touch packets from user touches into data packets relevant to the screen and display resolution of either the display or a portion of the display presenting the OS. Gesture-recognition software applies rules to the converted packets to determine which actions the user meant by the touches. And an application controlling a mouse cursor manipulates the mouse cursor according to the mouse actions. | 12-31-2009 |

| 20100228623 | TRACKING AD UNIT PERFORMANCE - Methods and computer storage media for tracking and reporting ad unit performance are described. Tags are associated with ad units and may be manually associated and/or extracted from content items to be presented on a webpage associated with an ad unit. Upon receipt of a request for an advertisement to be presented in association with an ad unit, one or more associated tags are also received. Performance of the ad unit may be tracked utilizing the associated tags and one or more performance data elements, for instance, click-through-rate, income generated by the ad unit, visitor data, number of impressions, and expected cost per thousand impressions (eCPM). Reports on the tracked performance may be generated as desired. | 09-09-2010 |
| 20100250331 | EVALUATING THE QUALITY OF WEB-BASED PROPERTIES - Methods, systems, and media are provided for evaluating the quality of web-based properties for use as hosts of advertisements. Properties are automatically and dynamically evaluated for appropriateness of content, for instance, based upon extracted keywords and/or contextual information categories. Upon submission of an advertisement request, properties determined to be of insufficient quality are served a neutral advertisement, served a message indicating that no advertisement will be served, or served nothing at all. Advertisements determined upon submission of an advertisement request to be of sufficient quality are served one or more non-neutral advertisements as requested. | 09-30-2010 |
