摘要:
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.

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.

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 replaceable cartridge for use in a minimally invasive allergy testing system includes a microneedle array; encapsulated allergens, and packaging to hold the array in alignment with the allergens. A method of manufacturing a replaceable cartridge is disclosed. A formable layer is placed on a mold having cavities and vacuum lines coupled to the cavities. Heat is applied to the formable layer and a negative pressure is applied to the vacuum lines to wrap the cavities with the formable layer. The wrapped cavities are filled with allergens. The filled cavities are covered with a plastic cover to form an encapsulated allergen assembly. A removable seal is applied over the plastic cover. A microneedle array having a substrate and at least one microneedle is formed. An energy storage device is coupled to the substrate to form a microneedle array assembly. The encapsulated allergen assembly is coupled with the microneedle array assembly.

A biomedical monitor is disclosed. The biomedical monitor has an array of moveable microneedles coated with a first chemical sensing media. The biomedical monitor also has an actuator configured to move at least one microneedle in the array of microneedles from a retracted position to an engaged position whereby the at least one microneedle enters a subject's skin. The biomedical monitor further has an optical system configured to illuminate the at least one microneedle during or after entering the subject's skin and monitor the first chemical sensing media from the at least one microneedle, whereby at least one biomedical characteristic is determined based on at least one spectral property of the monitored first chemical sensing media. A method of monitoring at least one biomedical characteristic is also disclosed.
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.
