摘要:
A method for monitoring at least one biomedical characteristic is disclosed. A first microneedle coated with one or more regions of a chemical sensing material is illuminated. One or more digital images are captured of the first microneedle, wherein at least one of the one or more digital images is captured after the first coated microneedle has been actuated to penetrate a subject's skin. Pixel information is spatially extracted from the captured one or more images to define one or more pixel sample areas corresponding to the one or more regions of a chemical sensing material. One or more spectral characteristics are determined for each of the one or more pixel sample areas. The at least one biomedical characteristic is determined for each of the one or more pixel sample areas based on the determined one or more spectral characteristics for each of the one or more pixel sample areas.

An allergy testing system has a microneedle array. The allergy testing system also has at least one coated allergen. The allergy testing system further has an activation system coupled to the microneedle array such that the at least one coated allergen is moved into contact with a subject as the microneedle array is moved from a resting position to a penetrating position. A method for determining a degree of reaction to one or more allergens by a patient in a minimally invasive manner is disclosed. One or more allergen coated microneedles is caused to penetrate into a skin of the patient. One or more images of at least one of the penetrations into the skin are captured. At least one of the captured images are analyzed to assess the degree of reaction to a specific allergen. Allergic reactivity data is output for at least one of the allergens.

An allergy testing system includes encapsulated allergens, a microneedle array, and an activation system coupled to the microneedle array and the encapsulated allergens such that the encapsulated allergens are moved into contact with a subject as the microneedle array is moved from a resting position to a penetrating position. A method for determining a degree of reaction to one or more allergens by a patient in a minimally invasive manner is also disclosed. Penetration of one or more microneedles into a skin of the patient is caused. Each of the penetrations into the skin is exposed with an allergen from each of the one or more microneedles. One or more images are captured of each of the penetrations into the skin. Each of the captured images are analyzed to assess the degree of reaction to the specific allergen. Allergic reactivity data is output for at least one of the allergens.

Image-based products are obtained from a digital motion picture source by utilizing a content playing and display system for (a) displaying a sequence of motion picture image frames from a digital motion picture image source containing motion picture contents, and (b) selecting one or more of the image frames for an image-based product and obtaining a unique frame identification for said one or more selected frames; a content management system that (a) utilizes the unique frame identification and determines whether at least one permissible image-based product can be made from said one or more selected frames, and (b), if a permissible image-based product may be made as determined, obtains file data corresponding to said one or more selected frames from a digital source file containg source information corresponding to the motion picture contents; an order management system for preparing order information for the permissible image-based product from the file data; and an order fulfillment system for generating the image-based product from the file data according to the order information.
摘要:
An apparatus and method for making an apparatus for skin testing includes a housing with an opening which defines a field of view of a skin testing region, an image sensing apparatus, an illumination apparatus, a binding apparatus, and an image processing controller. The image sensing apparatus is positioned with respect to the housing to capture images in the field of view provided by the opening. The illumination apparatus is positioned within the housing to direct light towards a portion of the field of view provided by the opening. The binding apparatus detachably secures the housing over the skin testing region and maintains a fixed distance between the image sensing apparatus and the skin testing region. The controller is configured to analyze test samples sites in each of the captured images from the image sensing apparatus and provide a skin test result for each of the test sample sites.
摘要:
A method of determining a prothrombin time is disclosed. A mediator is applied to a stratum corneum. The stratum corneum is penetrated to allow the mediator to enter a region containing interstitial fluid and interact with at least one capillary, causing blood and/or blood components to leak from the at least one capillary into the region containing interstitial fluid. A characteristic affected by the blood and/or blood components is measured in the region containing interstitial fluid which correlates to the prothrombin time. A system for measuring prothrombin time is also disclosed. The system has a mediator, one or more microneedles, and a processor directly or indirectly coupled to the one or more microneedles and configured to determine a coagulation change in blood or blood components in a region around the one or more microneedles after the one or more microneedles penetrate a stratum corneum.

A monitoring system includes a light source that illuminates at least a portion of a subject's eye with an incident light beam, and a contact lens with a coupler. The coupler couples the incident light beam into an aqueous humor of the eye, creating an aqueous light beam. The coupler also couples the aqueous light beam out of the aqueous humor of the eye, creating an output light beam. The monitoring system also includes a sensor that measures at least one spectral characteristic of the output light beam. The monitoring system further includes a processing system that determines at least one measurable characteristic of the subject based on the at least one spectral characteristic of the output light beam. A method for monitoring is provided, as well as a contact lens for use with a monitoring systems, and a method of manufacturing a contact lens.

A hyperspectral imaging system and methods thereof especially useful in fields such as medicine, food safety, chemical sensing, and agriculture, for example. In one embodiment, the hyperspectral imaging module contains a light source (1) for illuminating the object (6) in a light-tight housing (17). The light is spectrally filtered (4) prior to illuminating the object. The light leaving the object is then directed through imaging optics (T) to an imaging array (9). In another embodiment, the object of interest is illuminated by ambient light which is then compensated by a light modulation system. In this embodiment, the light emitted from the object is spectrally filtered prior to reaching the imaging array.
