Abstract: A computer system displays a representation of a field of view of the one or more cameras, including a representation of a portion of a three-dimensional physical environment that is in the field of view of the one or more cameras. The computer system receives a request to add a first virtual effect to the displayed representation of the field of view of the one or more cameras. In response to receiving the request to add the first virtual effect to the displayed representation of the field of view of the one or more cameras and in accordance with a determination that the first virtual effect requires a scan of the physical environment, the computer system initiates a scan of the physical environment to detect one or more features of the physical environment and displays a user interface that indicates a progress of the scan of the physical environment.

Abstract: An apparatus that can measure images of at least a portion of an eye and record data sets indicative of a neurological condition. A method interrelates an image and a data set to provide an interpretive result. The apparatus and method thereby provide guidance as to the presence of a medical condition in a patient. The apparatus and method can be used in an iterative measurement process, in which the apparatus attempts to discern normal health from a state of health that is not normal health. If the interpretive result is consistent with normal health, the process terminates, information is recorded, and an optional report is given. If the interpretive result is not consistent with normal health, the apparatus and method attempts to distinguish which condition is consistent with the data and images used, and can iterate with additional measurements and information to attempt to provide a useful interpretive result.

Abstract: An apparatus, system and method for performing a health correlation assessment based upon results an eye contrast sensitivity measurement test of a person. The health correlation assessment yields a predictive and probabilistic measure of the likelihood of the person appropriately assigned to a particular clinical health classification. Such an eye contrast sensitivity measurement can be used to identify people who are likely to be within a pre-Alzheimer's disease state or within Alzheimer's disease state of health and identify those who should seek further clinical and/or other types of testing to ascertain their actual health status and to determine an appropriate course of medical treatment.

Abstract: An apparatus for performing multiple procedures involving the eye. The apparatus includes a data collection apparatus and a data analysis module. The data collection apparatus for collecting a data set corresponding to at least a portion of an eye of a patient is configured to provide data indicative of at least two neurological disorders selected from the group consisting of glaucoma, macular degeneration, diabetic retinopathy, Parkinson's disease, Alzheimer's disease, dyslexia, multiple sclerosis, optic neuritis, LDS, head trauma, diabetes, and inappropriate responses to contrast sensitivity patterns. The data analysis module interrelates the data indicative of at least two neurological disorders to provide an interpretive result.

Abstract: Systems and methods for making and using handheld data readers comprising one or more fluid lenses. One or more fluid lenses are provided to allow a handheld data reader to perform such operations as reading indicia, including such additional operations as zooming, reorienting a viewing direction, focusing, adjusting an optical axis, and correcting for the effects of motion such as hand jitter. The fluid lens or lenses can be operated for example by applying electrical signals to fluid lenses comprising a plurality of fluids including at least one that is conductive and at least one that is non-conductive.

Abstract: A thermometric apparatus for determining a patient's temperature having a elongated sensing probe that is connected to a base housing. The insertion tip of the probe contains a outer shell and a spaced apart inner shell. The outer surface of the inner shell has a heater that is fabricated of a resistive thick film material and a heat sensor mounted thereon. The heater and the heat sensor are connected to a pair of thick film conductive traces which in turn are electrically attached by a flexible circuit board to leads running back to the base housing. The space between the two shells is filled by a thermally conductive epoxy.

Abstract: An apparatus that measures images of at least a portion of an eye and records data sets indicative of a neurological condition. A method of the invention employs a plurality of images, or a plurality of data sets, or at least one image and at least one data set to provide an interpretive result based on the interrelation of the images and data sets, such as by superposition. The apparatus and method thereby provide guidance as to the presence of a medical condition in a patient. The apparatus includes modules that observe images and/or data sets, that analyze the information, and that superpose the information. Modules are provided to store information, to provide data output, to provide reports, and to display information, including superposed images and data. Modules can be provided in hardware, in software, in firmware, or in combinations thereof.

Abstract: An apparatus that can discriminate various conditions of neurological health of a medical subject. The apparatus and method use the Frequency Doubling Technique to obtain data that is indicative of a state of health of a person being tested. Correlations to features such as for patterns of loss such as point-wise loss, peripheral vs. central loss, pattern standard deviation, mean deviation, and time to complete the test can be used to identify the condition of the person. The apparatus and method thereby provide guidance as to the presence of a medical condition in a patient. The apparatus and method can be used in an iterative measurement process, in which the apparatus attempts to discern normal health from a state of health that is not normal health.
