A three-dimensional (3-D) capture method and system having a 3-D contour capture device for capturing a surface contour of an object, a contoured support device for placing between the surface and the 3-D contour capture device that provides additional support to at least a portion of the surface, wherein a first contour captured by the 3-D contour capture device is modified based on a second contour captured with the contoured support device placed between the surface and the 3-D contour capture device to provide a resultant 3-D contour.

An apparatus and method for replicating the profile of a plantar surface of a foot are provided. It has particular application in the production of footwear insoles, the apparatus comprises a pressure resistant container (2); an elastic membrane (3) sealed to an open face of the container, thereby defining a variable volume chamber within the container; means for reversibly introducing fluid (15) into the chamber; a bed of elongate rods (13) of substantially equal length, in which, in one configuration, the rods can slide freely, one relative to another, along their length; and clamping means (10) for reversibly clamping the bed of rods so that the relative sliding movement of the rods is resisted; the bed of rods being arranged, in use, outside the container so that ends of the rods abut the face of the membrane. In this way, a positive and negative mould of the surface can be formed.

There is provided an apparatus configured to be used with a processing unit for determining a dimension of a selected surface of an object, the apparatus comprising i) a piece of stretchable fabric having a shape adapted to fit the selected surface of the object such that the piece of fabric stretches proportionally to the dimension of the surface when draped thereover; ii) a plurality of uniquely identified beacon devices disposed on the piece of fabric when unstretched in accordance with a first spatial configuration known a priori, where, when the piece of fabric is draped over and stretched by the surface, the beacon devices automatically shift position and form a second spatial configuration as a function of the dimension of the surface; and ii) electronic means for detecting the second spatial configuration and for generating data representing the second spatial configuration; where the processing unit is configured to receive data associated with the first and second spatial configurations and to determine the dimension of the surface as a function thereof.

A measuring device for measuring nuts, bolt heads, washers and the like that includes a body having a first end, an opposing second end, and a longitudinal reference line extending between the first end and the second end; a first pair of parallel surfaces of equal length, the first pair of opposing parallel surfaces longitudinally between the first end and the second end, the surfaces of the first pair spaced apart by a first distance; a second pair of parallel surfaces of equal length, the second pair of parallel surfaces longitudinally between the first pair of parallel surfaces and the first end, the surfaces of the second pair spaced apart by a second distance that is smaller than the first distance; and a pair of nonparallel surfaces connected at an obtuse angle, the opposing nonparallel surfaces longitudinally between the second pair of opposing parallel surfaces and the first end.

The invention relates to a measuring method and measuring device for the stick span length of a cylindrical straight tooth involute spline ring gauge. The measuring method provided by the invention comprises the following steps: (1) oppositely installing two symmetric measuring hooks on a measuring base and tailstock of a horizontal length measuring instrument and installing measuring heads on the hook tips of the measuring hooks, wherein the measuring heads comprise a knife edge measuring head and a plane measuring head and the knife edge measuring head and a spline tooth slot of an internalspline are mutually perpendicular; (2) carrying out zero calibration, namely adjusting the two measuring heads to be in parallel; fixing a combined measuring block on an operating platform of the horizontal length measuring instrument by utilizing a measuring block clamp; adjusting the operating platform and enabling the measuring claw operating surface on the measuring block and the knife edge surface of the knife edge measuring head to be parallel; setting the instrument to be zero; (3) taking down the measuring block and installing the measured spline ring gauge, wherein a measuring stick is installed in the tooth slot of the measured spline ring gauge; and (4) enabling the knife edge measuring head to be in contact with the measuring stick; adjusting the operating platform; and reading an indicating value of the instrument and adding the actual value of the measuring block for zero calibration to obtain the stick span length of the measured spline ring gauge.

A posture analyzer for analyzing a patient's spine having an upright standard secured to a base resting on a floor. A rectangular frame has one side frame member secured to the upright standard at a selected height. The frame member supports a markable panel, which panel includes an orthogonal grid pattern and a normal spine depiction on the panel. A bar holder is slidably secured to a second side frame member. The bar holder is moveable in the vertical direction along the second side frame member. The bar holder includes means for slidably holding a bar which extends in a horizontal direction parallel to the planar surface of the panel. A roller is secured to an end of the bar for rolling up and down a patient's spine, and a pen is secured to the opposite end of the bar for marking on the planar surface of the panel. When the roller is moved vertically and horizontally along a patient's spine, the pen makes a corresponding tracking mark on the panel.

A nail gauge tool is provided for quickly and accurately measuring nail shape and nail size. The nail gauge offers several arch-shaped openings for matching to and measuring a natural nail. As the measurement result, the nail arch shape information and nail arc length information along the natural nail's width direction are obtained for manufacturing custom-fit artificial nails. The nail gauge tool is advantageously small and suitable for use inside a nail salon.

The present invention is a calibration and measurement system designed primarily for use in the rapid evaluation and characterization of open or visible wounds in patients. The invention in a preferred embodiment comprises a set of colored concentric rings, constructed of paper or synthetic material. The practitioner removes only as many rings, from the center outward, until the entire wound is visible within the open aperture at the center of the remaining rings. The area dimensions of the wound are then read out from the size of the inner remaining ring. Photography optionally records the wound appearance and size. A related system is developed for linear dimensioning of wounds. This invention is also designed to standardize the color scheme for accurate photography wound description. This color scheme is also applicable to a linear device to accurately describe wound size. The invention is also useful in forensic and accident investigations.

A pipe fitting wireform which when threaded into a fitting allows a user to measure center-to-end or end-to-center of the fitting to determine the length of a pipe needed to connect a pair of pipe fittings in a pipe assembly. The fitting wireform is a coil with a free end bent laterally to form a tang. The fitting wireform having an outside diameter substantially equal to the nominal size of the pipe fitting with substantially the same number of turns per inch as the pipe fitting such that the pipe fitting wireform can be threaded into the pipe fitting.
