Provided is a size measurement system for measuring the size of a user's foot, said system characterized by comprising: a size measurement instrument which is formed from a stand for the user to place the foot thereon, and a plurality of markers which are positioned in the periphery of the stand; and a measurement terminal which captures an image of a state in which the user has placed the foot on the stand in the size measurement instrument such that the plurality of markers can be recognized from a plurality of directions, and which computes size data for the foot from contour information for the foot obtained through the image capture from each of the directions

A device and methods for maintaining patient registration in surgical navigation, involving: obtaining a patient position in a tracking system frame of reference, based on a fiducial marker array affixed in a first position relative to the patient; receiving an initial surface scan depicting the patient and the fiducial array; responsive to receiving an intraoperative image depicting the patient: obtaining a position, in the tracking system frame of reference, of the fiducial array affixed in a second position relative to the patient; receiving a secondary surface scan depicting the patient and the fiducial array; detecting a deviation in a position of the fiducial marker array relative to the patient between the initial and secondary surface scans; and applying the deviation to the position of the patient to generate an updated position of the patient in the tracking system frame of reference, based on the fiducial array affixed in the second position.

Systems and methods use a three-dimensional snapshot of an infant, child, adolescent, or adult where the subject may have bent legs and an unaligned head position, to provide an estimate of human length. The system identifies anatomical features from the digital information and generates a virtual skeleton. The cumulative distances between pseudo-joints of the virtual skeleton provide an estimate of human length. Comparing length estimates from multiple three-dimensional snapshots of the same individual acquired over time provide an indication of growth of the infant, child, or adolescent. Daily estimates of length can detect growth faltering sooner than less frequent estimates of length, which can lead to timely intervention.

A system (10) for detecting and displaying baropostural parameters comprises a platform (11) with a footplate (15) intended to accommodate a person standing on it and provided with sensors for detecting the pressure distribution of the imprint of the two feet on the footplate. An electronic acquisition device (32) is connected to the sensors for digital acquisition of the pressure distribution in order to create a map of the pressure points of the feet on the footplate. Calculation means (33a) are designed to calculate, for each foot and for both feet on the footplate, the geometric centers (52, 53, 54) and the barycenters (55, 56, 57) of the map of the pressures and display means (33b) display on a screen (31) a graphical representation of the imprints of the two feet on the footplate together with the corresponding geometric centers (52, 53, 54) and barycenters (55, 56, 57) calculated by the calculation means. The footplate may have a rear part (15) which can be raised for simulating shoe heels underneath the heels. Front and/or lateral telecameras (19, 20) may be provided in order to provide further postural data.

The present invention is directed to systems and process for detecting a febrile condition in screening of multiple or large groups of persons for the likelihood of infectious diseases. The system comprises a temperature measurement device having at least a processor, a display, temperature sensor, camera module, and facial recognition software. The display may include a positional overlay. The system further includes a database containing baseline temperatures for a number of persons, including baseline temperatures by age group and by gender. An input device optionally may identify the specific person or provide survey questions to a person to further determine a febrile condition. Based on the baseline temperatures, measured temperature and other characteristics of the person, a febrile condition may be determined. Additionally, the system may include a secondary screening component providing nasal swabbing or saliva testing.

A system and method for assessing a patient's balancing ability in order to facilitate ascertaining the patient's current medical status. The system includes a balance plate for measuring the center of gravity dynamic weight distribution in combination with a sensor for measuring the patient's fine motor skills.

A medical diagnostic apparatus includes a controller; a user interface; a platform having a horizontal surface; and at least one visible light image sensor positioned below the horizontal surface that is capable of producing a diagnostic visible light image of a bottom portion of a foot or feet positioned on the horizontal surface. At least a portion of the horizontal surface is transparent to visible light. The apparatus may further include at least one infrared image sensor positioned below the horizontal surface that is capable of producing a thermal image of the first target area. The apparatus may further include sensors positioned above the platform capable of producing diagnostic visible light images or thermal images of a top portion of the user's foot or feet. The apparatus may further include a weight measurement system coupled to the platform.

Sample processing methods and systems to collect a biological sample. A device may be configured collect a predetermined volume of a sample in sample chamber, and seal the chamber upon activation. The device may be further configured to mix the mix the sample with a predetermined volume of a reagent and/or mix the sample and the reagent in a pre-determined ration.

In a method and apparatus for supporting a user when positioning an accessory for a magnetic resonance examination on an examination object, the actual position of the accessory is acquired by an acquisition unit, and a target position of the accessory is determined by a detection unit. The actual position and the target position of the accessory are compared with regard to deviation of the actual position from the target position of the accessory. Output information representing any deviation that is found to exist is provided to a user via an output unit.

A system and method is presented for cuff-less blood pressure measurement in a mobile device. A key aspect of this disclosure is the discovery of a new location for blood pressure measurement at the fingertip of a subject and that reflectance-mode photoplethysmography can be used to help make this measurement. Through experiments in human subjects, it was discovered that it is indeed possible to measure systemic blood pressure by having a subject press the fingertip against a reflectance-mode photo-plethysmography-force sensor unit under visual guidance and then compute blood pressure from the resulting variable-amplitude blood volume oscillations and applied pressure via an oscillometric algorithm.
