Abstract: Described herein are systems and methods for estimation of vital signs using camera data. In one or more examples of the disclosure, a RGB camera (i.e., a visible spectrum camera) can be used to collect imaging data of one or more subjects. The acquired video can be analyzed to determine the presence of a region of interest (ROI) in the field of view of the video. Using the pixel information of the identified region of interest, the system and methods can estimate both heart rate and respiratory rate of a subject by observing the periodicity of change in color of the pixels in the region of interest. The change in color can be monitored by determining the power spectral density (PSD) of each pixel and monitoring the changes in PSD over time.

Abstract: Various embodiments directed to a work stand for holding a microscopic collection device for collecting a microscopic sample from a target surface, are provided. The work stand includes a first slit formed on a top surface of the work stand and capable of holding a first microscopic collection device comprising a first holding element and a first collection platform, wherein the first collection platform of the first microscopic collection device is perpendicular to the top surface. A second slit formed on the top surface of the work stand and capable of holding a second microscopic collection device comprising a second collection platform and a second holding element at an angle to the second collection platform perpendicular to the top surface of the work stand.

Abstract: A microscopic collection device, method for collecting a microscopic sample from a target surface, and the work stand for holding the microscopic collection device are provided. The microscopic collection device includes a holding element comprising a handle at one end and a collection platform connected to the holding element at a second end. The collection platform includes a collection surface on which the microscopic sample is deposited when the microscopic collection device comes into contact with the target surface. A tape is inserted through a slit and wrapped around the collection platform. The work stand includes a slit capable of holding the microscopic collection device such that the collection platform is perpendicular to the top surface of the work stand. A microscopic sample, collected using the microscopic collection device, is not only collected from the target surface but is also concentrated onto the collection face of the tape.
