Systems, methods and a sensor alignment mechanism are disclosed for medical navigational guidance systems. In one example, a system to make sterile a non-sterile optical sensor for use in navigational guidance during surgery includes a sterile drape having an optically transparent window to drape the optical sensor in a sterile barrier and a sensor alignment mechanism. The alignment mechanism secures the sensor through the drape in alignment with the window without breaching the sterile barrier and facilitates adjustment of the orientation of the optical sensor. The optical sensor may be aligned to view a surgical site when the alignment mechanism, assembled with the sterile drape and optical sensor, is attached to a bone. The alignment mechanism may be a lockable ball joint and facilitate orientation of the sensor in at least two degrees of freedom. A quick connect mechanism may couple the alignment mechanism to the bone.

The disclosure demonstrates an attachment apparatus for optically coupling a mobile device camera to a lens of a medical examination device. The device incudes an attachment body wherein the proximal side of the attachment body is attached to a mobile device via a magnetic array that may be positioned in at least two different positions. The distal side of the attachment device includes an array of magnets to connect with the lens of a medical device. In one or more of the magnetic arrays at least one pair of axially magnetized magnets are positioned in antiparallel arrangement relative to each other to reduce the expanse of a magnetic field while at the same time increasing the magnetic field strength close to the magnetic poles.

A dynamic wake-up alarm is provided-for, including a clock, a contactless biometric sensor, a processor, memory, and a speaker. The processor may be configured to receive a wake-up rule based on at least two wake-up criteria including a time from the clock and data from the biometric sensor, and evaluate whether the criteria are met to activate an alarm.

There is set forth herein a system including a camera device. In one embodiment the system is operative to perform image processing for detection of an event involving a human subject. There is set forth herein in one embodiment, a camera equipped system employed for fall detection.

Disclosed is a method for producing a horseshoe, wherein the following steps are carried out: a) at least partially viewing the hoof (16) to be shod in order to determine the required measurements for producing a shoe that fits the hoof, b) processing the measurements in order to deduce a provisional shape of the horseshoe, c) recording definitive parameters of the horseshoe, and d) producing the horseshoe on the basis of the definitive parameters. Before step b), the potential existence of at least one area of inflammation and/or at least one area of reduced blood circulation of the foot of the horse, of which the hoof is to receive the shoe, is determined by an infrared detector (17), and in step b), the existence of at least one such area is taken into account in order to determine the provisional shape and/or the structure of the horseshoe.

Provided are a skin evaluation apparatus, a skin evaluation method, and a non-transitory computer readable recording medium storing a skin evaluation program capable of evaluating gloss of skin in consideration of both of a physical feature of the skin and an optical feature of the skin to quantitatively evaluate gloss of the skin closer to a practical point of view. The skin evaluation apparatus includes a shape information acquisition unit 22 that acquires information on a surface unevenness shape of the skin; an optical feature information acquisition unit 23 that acquires information on an optical feature of the skin; and an evaluation unit 24 that evaluates gloss of the skin on the basis of the information on the surface unevenness shape and the information on the optical feature.

This document describes assessing cardiovascular function using an optical sensor, such as through sensing relevant hemodynamics understood by pulse transit times, blood pressures, pulse-wave velocities, and, in more breadth, ballistocardiograms and pressure-volume loops. The techniques disclosed in this document use various optical sensors to sense hemodynamics, such as skin color and skin and other organ displacement. These optical sensors require little if any risk to the patient and are simple and easy for the patient to use.

A method for test strip recognition and interpretation is provided. The method includes the following steps. A plurality of test strips are provided, wherein the test strips are configured to examine a plurality of physiologic parameters respectively, and the test strips respectively have a plurality of color characteristics corresponding to the physiologic parameters respectively. A plurality of physiologic parameter examinations are performed to the corresponding test strips respectively, so as to obtain a plurality of test reactions. An image of the test strips is captured. The color characteristics and the test reactions of the test strips are obtained according to the image. The physiologic parameters examined by the test strips respectively are obtained according to the color characteristics. The physiologic parameters examined by the test strips are matched with the test reactions to obtain a plurality of physiologic parameter examination results.

An abnormality processing system is provided capable of executing appropriate processing in cases where an abnormality occurs in a worker's living body. A management computer 300, if determining that an abnormality is present in a worker's living body, transmits an abnormality signal to an administrator terminal 100, a work device 200, a worker camera 20 and a surveillance camera 50. When receiving the abnormality signal, the administrator terminal 100 displays an image showing that an abnormality has occurred. When receiving the abnormality signal, the work device 200 stops operation. When receiving the abnormality signal, the worker camera 20 and the surveillance camera 50 transmit to the management computer 300 imaging data containing at least data of images before and after a timing at which the abnormality has occurred in the worker's living body.

A method for monitoring physical conditions of an operator of a driving apparatus is described. The method includes obtaining an identity of the operator, acquiring signals indicating a physical condition of the operator, and determining whether the physical condition as indicated by the signals has breached a predetermined threshold. Further, when it is determined that the physical condition as indicated by the signals has breached a predetermined threshold, the method includes generating a first status indicating the operator suffers an abnormal physical condition, obtaining a current location of the driving apparatus, generating a first notification based on the first status, the first notification indicating the identity of the operator and the current location of the driving apparatus, the first notification describing the first user suffers the abnormal physical condition, and transmitting the first notification to a data receiver in a healthcare facility.
