A pitch compensated inductive position encoder includes a scale comprising first and second tracks including periodic patterns having a wavelength W, a detector, and signal processing. The second track pattern may be shifted along the measuring direction by a pattern offset STO relative to the first track pattern. In the detector, first-track and second-track field generating coil portions generate fields in first and second interior areas aligned with the first and second pattern tracks, respectively. First and second sensing coil configurations that are aligned with the first and second tracks, respectively, are offset relative to one another by STO+/0.5*W along the measuring direction. In various embodiments, the first and second sensing coil configurations may have the same sequence of individual coil polarities if the generated field polarities are different, and may have inverted or opposite sequences if the generated field polarities are the same.

A grid pattern which includes a transparent window and handle is provided herein. Levelling and angle measurement components are provided that allow a user to determine balance and symmetry when working with subjects and the present invention. A hand held or floor stand can be used to steady the invention,

A fitting or measuring square with measuring indicia configured with a primary rectangular form and triangle collinear with one side of the primary rectangle and a secondary rectangle partially collinear with the triangle whereby the measuring square is provided with multi function indicia.

An inspection and measurement device includes a body defining a first planar face within a first bounded area, a first reference feature disposed on the first planar face within the first bounded area and corresponding with a first measurable parameter, and at least a second reference feature disposed on the first planar face within the first bounded area and corresponding with a second measurable parameter. The first and second reference features are positioned within the first bounded area for placement adjacent an element bearing the respective one of the first and second measurable parameters. The first and second reference features overlap within the first bounded area in at least one direction.

A rotor position indicator system may include a side plate and a first rotor width indicator plate. The side plate may be positioned on a side of an earth moving milling machine, and the first rotor width indicator plate may be inset on an external face of the side plate. The first rotor width indicator plate may include a plurality of markings, with each marking corresponding to a rotor position.

A suspension assembly for a cycle includes a link and an indicator having a central opening. The indicator includes a first retention feature. A pivot assembly is disposed in the link. The pivot assembly includes a second retention feature. The first retention feature and the second retention feature cooperate to axially retain the indicator on the pivot assembly while allowing rotational movement between the indicator and the pivot assembly when a force threshold is exceeded.

An electrical measuring device including an elongated member. The elongated member is at least 52 inches in length. There is at least one fastening strap located at a top end of the elongated member. The strap can secure the elongated member in an upright manner when not in use. There is a plurality of indicia located on the elongated member. The indicia display various measurements that correspond to specific heights of electrical implements. Specifically, the indicia specify heights for outlets and switches. The elongated member can further have various colors disposed thereon. The colors align with the different indicia.

A tape measure apparatus including a housing having a base-wall, a retractable measuring tape disposed within, and a first-set of indicia markings beginning at a first-end of the base-wall and terminating at a second-tape-end of the retractable measuring tape. The first-set of indicia markings comprise of graduated measurements for measuring a distance between two surfaces or objects. The tape measure apparatus is useful for enabling a user to accurately measure the distance without bending or distorting the retractable measuring tape.

Smart Scale Ruler is an electronic architect's scale having a triangular shaped ruler body. The Smart Scale Ruler has a changeable electronic display for displaying a custom or the desired scale of any unit of length, for a document or plan. A set of depressible buttons function as the inputs for the value of the reference point a user wishes to base the custom scale off of, as well as different settings for the device, in order to display the correct scale on the electronic display.
