20130045813 | SWING PLAY SYSTEMS AND METHODS OF PLAY - A play swing system includes a safety harness attached to each seat, as well as other features for interactive and competitive throwing and tossing games. The safety harness may incorporates various games features, and thus encourage use in activities that require at least one free hand, or otherwise increase the risk of slippage and falling from the play swing seat. Various embodiments accommodate as well as challenge the spatial perception, dexterity and reflexes of players of different ages. For examples, younger players might compete by throwing objects at a fixed target mounted on the ground. In other embodiments, the target is moving in synchronization with the oscillatory motion of the adjacent players swing by a physical coupling or attachment. Interactive play is encouraged at the higher skill levels by configuring the targets associated with adjacent seats to face each other. In this embodiment, the players oscillate in opposite directions so that they are closest to the target when the relative velocity is highest. The objects of the associated games can be building a higher score, as well as soaking the other player(s) with water supplied by an external source and actuated by instantaneous or accumulated contact of a throwing object with a target. | 02-21-2013 |

20080293580 | Methods for Detecting and Measuring Specific Nucleic Acid Sequences - The invention provides novel oligonucleotides and methods of using the same for detection or measurement of specific nucleic acid molecules. The invention also features nucleic acid arrays comprising the oligonucleotides of the invention. An oligonucleotide of the invention comprises (1) a reporter-binding sequence capable of hybridizing to a fluorrophore-labeled reporter sequence and (2) a hairpin-forming sequence capable of forming a stem-loop. Formation of the stem-loop modifies (e.g., quenching) the fluorescence signals of the reporter sequence when the reporter sequence is hybridized to the oligonucleotide. This can be achieved, for example, by bringing one or more guanine based in the oligonucleotide into close proximity to the fluorophore(s) of the reporter sequence by virtue of the formation of the stem-loop. Disruption of the stem-loop, such as by hybridization of a target sequence to at least part of the hairpin-forming sequence, produces a detectable change in the fluorescence signals. | 11-27-2008 |
20110210239 | PHOTON EVENT DISTRIBUTION SAMPLING APPARATUS AND METHOD - Locations of the origins of the photons are acquired from a scanned sample with reference to a scan frame. The location on the sample from which a photon was emitted is inferred from the location of the scan as commanded by a scan drive signal, a feedback signal related to the position of the scan device, or alternatively by the point in time during a scan at which the photon is detected. A position function, e.g., photon probability density, is associated with a photon position. Summing or other processing of photon probability density functions can require fewer photons to converge to an ideal density distribution associated with an image feature than are required using conventional pixel binning. Stored data can be mapped into pixels or voxels of a display or otherwise processed. Original data remains available in the digital storage for post-hoc analysis. Imprecision introduced by the display process need not adversely affect the precision of the collected data. | 09-01-2011 |
20110211056 | SYSTEMS AND METHODS FOR SPATIALLY CONTROLLED SCENE ILLUMINATION - A scene illumination system is provided that produces spatially uniform or controlled brightness levels for machine vision applications. The system includes a camera, multiple light sources that preferentially illuminate different regions within the camera's field-of-view, and a processing unit coupled to the camera and light sources. Focal regions of the light sources within the camera's field-of-view are sampled to determine average regional brightness and compared to target brightness levels. The processing unit controls the light/sources to increase or decrease illumination levels to converge toward the target brightness levels within the field-of-view. This modulation of the light sources may be repeated with successive video images until target brightness levels are achieved. Once achieved, the iterative feedback control may be locked-in for some applications, while for others, the iterative process may continue periodically or continuously to account for different scenes or changes in lighting conditions. | 09-01-2011 |
20120293773 | SYSTEMS AND METHODS FOR MEASURING REACTIONS OF HEAD, EYES, EYELIDS AND PUPILS - Systems and methods are provided to measure reaction times and/or responses for head, eye, eyelid movements, and/or changes in pupil geometry. The system includes eyewear or headwear including one or more eye-tracking cameras for monitoring the position and geometry of at least one eye and its components of the user, one or more scene cameras for monitoring the user's surroundings, and one or more processors to determine reaction times. Optionally, the system may include one or more of a multi-axis accelerometer to monitor head movements, light sources to trigger visual evoked responses, and/or electronic inputs that may be used to indicate the time of occurrence of external reference events. Measured reaction times and other measurements may be monitored for use in a range of applications. Responses and reaction times may be measured continuously over extended periods, even over a lifetime to measure consequences of the aging process. | 11-22-2012 |
20120294478 | SYSTEMS AND METHODS FOR IDENTIFYING GAZE TRACKING SCENE REFERENCE LOCATIONS - A system is provided for identifying reference locations within the environment of a device wearer. The system includes a scene camera mounted on eyewear or headwear coupled to a processing unit. The system may recognize objects with known geometries that occur naturally within the wearer's environment or objects that have been intentionally placed at known locations within the wearer's environment. One or more light sources may be mounted on the headwear that illuminate reflective surfaces at selected times and wavelengths to help identify scene reference locations and glints projected from known locations onto the surface of the eye. The processing unit may control light sources to adjust illumination levels in order to help identify reference locations within the environment and corresponding glints on the surface of the eye. Objects may be identified substantially continuously within video images from scene cameras to provide a continuous data stream of reference locations. | 11-22-2012 |
20130114850 | SYSTEMS AND METHODS FOR HIGH-RESOLUTION GAZE TRACKING - A system is mounted within eyewear or headwear to unobtrusively produce and track reference locations on the surface of one or both eyes of an observer. The system utilizes multiple illumination sources and/or multiple cameras to generate and observe glints from multiple directions. The use of multiple illumination sources and cameras can compensate for the complex, three-dimensional geometry of the head and anatomical variations of the head and eye region that occurs among individuals. The system continuously tracks the initial placement and any slippage of eyewear or headwear. In addition, the use of multiple illumination sources and cameras can maintain high-precision, dynamic eye tracking as an eye moves through its full physiological range. Furthermore, illumination sources placed in the normal line-of-sight of the device wearer increase the accuracy of gaze tracking by producing reference vectors that are close to the visual axis of the device wearer. | 05-09-2013 |

20140184775 | EYE TRACKING WEARABLE DEVICES AND METHODS FOR USE - Devices and methods are provided for eye-tracking, e.g., including a freeform optical assembly and/or a modular design. In an exemplary embodiment, a device and method are provided that includes a wearable device on a user's head, the wearable device including a scene camera oriented to capture images of the user's surroundings. The user may perform a predetermined action with the user's eye to activate a photo feature of the wearable device, gaze at a region within the user's surroundings, the wearable device determining a focal point and limited field-of-view for the camera imaging field based on the center point, and activate the camera to capture an image of the limited field-of-view centered around the focal point. | 07-03-2014 |
