5 results about "Grading scale" patented technology

Disclosed are methods, systems, media, apparatus, devices, and other implementations, including a method that includes determining blood flow characteristics at an ocular surface of an eye of a patient, determining characteristics of blood vessels at the ocular surface of the eye based on the determined blood flow characteristics, and deriving one or more ocular redness grading scales indicative of inflammation levels of the eye of the patient based on the determined characteristics of the blood vessels at the ocular surface of the eye.

A grading instrument and method for yield strength of woody plant branches, belonging to the forestry field, is disclosed. The instrument includes a semi-circular platform with a rotating shaft at its center. A torque sensor connected to a drive mechanism is mounted on the rotating shaft. Grading scales for yield strength of woody plant branches are arranged around the platform. A circumferential actuation mechanism is arranged on the platform in a horizontal direction perpendicular to the rotating shaft. An X-ray camera is mounted on the platform, and a display screen is located on the side of the platform. X-axis and Y-axis position adjustment mechanisms are connected to the rotating rod and the fixed rod, respectively. By using the grading instrument to classify the yield strength of various plant branches and determine the grading method, this provides a more effective application standard and testing instrument for applications in weaving techniques, landscaping, and bonsai design, as well as for predicting wind breakage risk.

A single use disposable elapsed time indicator and methods for using same include an indicator that can have a flexible chamber for holding an aqueous medium and a slot with a viewing window and a longitudinal axis. The slot is connected to the chamber via a passage having a breakable seal therein. An absorbable material is located within and at a first end of the slot that swells upon exposure to the aqueous medium. A graded scale is also included along the longitudinal axis of the slot to indicate periods of elapsed time. The absorbable material is configured to expand from the first end of the slot toward an opposing end of the slot along the longitudinal axis and thereby mark elapsed time on the graded scale.

This invention belongs to the field of computer medical technology and relates to an automatic assessment method for cranial morphology based on pediatric CT images. The method involves acquiring original pediatric cranial CT images; identifying the voxel coordinates of the nasal root point, left tragus point, and right tragus point in the original pediatric cranial CT images; redirecting the original pediatric cranial CT images to a standard anatomical coordinate system to obtain a normalized cranial image; performing three-dimensional connected component extraction and morphological closure operations on the normalized cranial image to obtain a binary mask of the complete skull; locating the pediatric cranial measurement plane and extracting the skull contour to obtain a collision point set; calculating the cranial asymmetry index and cranial proportion; and comparing the results with a predefined clinical grading scale to generate an assessment result. This invention solves the problems of weak anti-interference ability, strong subjectivity in key point localization, lack of standardized spatial alignment, and fragmented automated processes in existing technologies.

The utility model provides a packing material grading device which comprises a grading scale body, side plates on the two sides of a conveying belt of the grading scale body are a first side plate and a second side plate respectively, a push plate is arranged on the first side plate and close to the output end side of the conveying belt, and a collecting frame is fixedly connected to the position, corresponding to the push plate, of the outer side of the second side plate. The pushing plate can move in the width direction of the upper surface of the grading scale body, an ejector rod located above a conveying belt of the grading scale body is fixedly connected to the side, facing the second side plate, of the pushing plate, a U-shaped groove is formed in the second side plate, a limiting plate capable of being opened and closed is arranged in the U-shaped groove, one end of the limiting plate can rotate along one side of the U-shaped groove, and the other end of the limiting plate can rotate along the other side of the U-shaped groove. The other end of the ejector rod abuts against the other side of the U-shaped groove, and the ejector rod can eject the limiting plate open. The device has the beneficial effects that the device is simple in structural design and convenient to operate, and the mistaken removal operation of the qualified packages is effectively reduced on the premise of not influencing the continuous conveying of the qualified packages.
