The inward-side face may include a curved portion, a leg portion and a notch configured to receive the cutting edge. The first face includes a curved edge, a plurality of horizontal lines and a plurality of vertical lines. When the cutting edge is received in the notch, and the curved portion abuts the top face of a bolt, the plurality of horizontal lines is configured to measure a vertical distance from a center of the top face to the cutting edge, and the plurality of vertical lines is configured to measure a horizontal distance from the center of the top face to the cutting edge.

A method and apparatus for simulating, measuring and recording a subject's ability to perform a varying range of barrier reaches is provided. The apparatus includes a variable barrier reach instrument for simulating an actual barrier that the subject may lean against in performing a work task The variable barrier reach instrument may include a physical barrier having a substantially horizontal upper surface at a height above a base point. A sensing and recording device may be positioned proximate to the variable barrier reach instrument for sensing and recording a plurality of barrier reach data points as the subject bends forward against the physical barrier. A computer and an associated software program are also provided into which the recorded data points are entered. An algorithm may be contained within the software program that generates an interpolated arc reflecting the subject's reach at the physical barrier height from the recorded data points. Storage means associated with the computer are further provided for storing the interpolated arc and recorded data points.

The binding guide is provided by a substantially rigid translucent non-regular hexagon body, having first, second, third, fourth, fifth and sixth peripheral edges. The first, second and third peripheral edges define a generally rectangular section of the translucent body. The fourth, fifth and sixth peripheral edge sections define a generally obtuse pointed section of the translucent body. At least one isosceles triangular ruling for establishing a binding margin is aligned to the third peripheral edge, as is at least one binding width guideline proximate to the third peripheral edge. At least one set of aligned apertures is disposed within the translucent body to uniformly fold the binding margin. And associated method of use is also provided.

A measuring board having a simple structure is to be provided. A measuring board includes a main body having a foldable structure, and the main body includes a placement part on which a foot is placed and that includes a measurement marker, a wall part provided adjacent to the placement part and configured to position a heel during measurement, and supporting structures and that support the wall part. With such a configuration, a measuring board having a simple structure can be provided.

A mask size gauge for selecting a size of a mask in accordance with a distance in a height direction between an upper reference part in an upper portion of a face of a wearer, and a lower reference part in a lower portion, includes: a reference position indicating portion indicating that the reference position indicating portion is to be placed at a height position of the upper reference part on an outer lateral side of an eye of the wearer; and a size indicating portion that is located at a position which is closer to a middle of the face than the reference position indicating portion, and that indicates the size of the mask according to a height position of the lower reference part.

An apparatus for measuring a dimension of a freight item. The apparatus includes an elongate gauge member having a sequence of machine-readable codes visible along its length. Each of the machine-readable codes represents a length value corresponding to a position along the gauge member. The apparatus also includes a marker device, movable along the gauge member, for designating a selected position. The marker device includes a machine-readable reference symbol on an external surface thereof, with the reference symbol being located on the marker device such that in use the reference symbol on the marker device and a subset of the machine-readable codes on the gauge member are simultaneously visible. In a preferred embodiment the elongate gauge member includes a coilable tape and the marker device includes a housing within which the coilable tape is enclosed. A system including the measuring apparatus together with a mobile computing device is also disclosed.

A measurement device that allows all users to conveniently and discreetly determine appropriate general footwear measurements at any age is disclosed. The device may include a housing having a contact edge configured to receive the heel or a first side edge of the user's foot, a retractable tape configured to extend outwardly from the housing, and a toe flange proximate the distal end of the retractable tape that is configured to receive the toe or a second side edge of the user's foot.
