A method for forming an assembly of a plurality of components. The method includes receiving, by a controller, one or more assembly identification parameters and controlling, by the controller, a light array disposed along an assembly jig based on the one or more assembly identification parameters.

A ruler surface structure for clear marks display in a dim light mainly comprises a ruler surface and a brightening layer. The ruler surface is marked with marks which are characters or lines. The brightening layer is laid on the marks to enhance the display and identification effect of the marks. By using the different light sensitivities formed by the brightening layer on the marks and the other regions of the ruler surface, including the functions of light reflection or luminescence, the marks can be clearly displayed and identified in the dim light.

A tape measure light attachment which can be deployed on the extended measuring tape of a tape measure for illumination purposes may include an assembly housing. A light assembly may be provided on the assembly housing. The light assembly may be selectively configurable to emit light upon activation. A mount assembly may be provided on the assembly housing. The mount assembly may facilitate attachment of the assembly housing to the measuring tape. A hook assembly may be provided on the assembly housing. The hook assembly may be configured to facilitate engagement of the assembly housing with a retaining structure to retain or immobilize the assembly housing on the measuring tape as the measuring tape is extended from the tape housing of the tape measure to measure a length or distance from the point of engagement between the hook assembly with the retaining structure and the tape housing.

The present disclosure provides a distance measuring device configured to measure a distance between an initial position and a target position, the distance measuring device includes: a marking assembly configured to generate a mark on the initial position as a first measuring datum and a measuring structure configured to measure the distance between the initial position and the target position according to the first measuring datum. The present disclosure further provides a distance measuring method.

A length measuring device and a length measuring system are provided, in which the length measuring device includes a casing, a first rotating portion accommodated in the casing, and rotated with a portion of a circumference thereof being exposed out of the casing and in contact with an object to be measured, a first sensing portion which senses an amount of rotation of the first rotating portion, and a controller which converts the amount of rotation of the first rotating portion into length measurement. Additionally, the length measuring device may further include a second rotating portion coiled with a strip by a plurality of times, and rotated according to the strip being withdrawn or retracted through an outlet formed in the casing, and a second sensing portion which senses an amount of rotation of the second rotating portion, in which the controller may convert the amount of rotation of the second rotating portion into length measurement.

A tool such as a tape measure, including a lighting system is shown. The lighting system includes a light source configured to direct light forward and strong enough to act as a flashlight. The tape measure further includes a housing designed to be compact and rugged enough to protect the internal components related to the lighting system from coming loose or suffering damage due to an impact or vibrations.

A tape rule assembly includes a linear optical encoder for sensing human-readable graduations of length disposed on a surface of a tape, without requiring any other machine-readable indicia to be present on the tape. The optical encoder includes two optical sensors disposed in a sensor holder pivotably disposed in the tape rule housing and configured to be displaced relative to one another in the housing along both the x axis and the z axis, a set of intersecting x, y and z axes being defined relative to a tape exit in the tape rule housing.

An Improved Measuring System structured and arranged to combine a high-quality, high-precision steel tape-measure with both a horizontal and vertical laser level measuring tool, thus combining two essential tools into one compact, convenient device that can be easily clipped to one's belt, or magnetically attached to metal surfaces. Complete with a carrying case, and LED screen which displays the laser acquired measurements, as well as being deal for professional contractors and household do-it-yourselfers, the Improved Measuring System will preferably leave room in the toolbox, allow one to measure without assistance if desired, and deliver accurate and superior results on the jobsite or around the home.

A tape measure having a light emitting device includes a housing, a reel received in the housing, and a blade wound on the reel to be extended or retracted through an inlet of the housing, and further includes a first case, a second case coupled with the first case to form the housing, a light emitting portion positioned in front of the center of the reel around the inlet of the housing, and a light emitting circuit portion positioned in the rear side of the center of the reel by facing the light emitting portion, wherein the light emitting circuit portion includes a circuit board disposed on a rear lower side of the housing, and the first case and the second case provide circuit receiving spaces for receiving the circuit board, respectively.

A measuring and marking assembly includes a tape measure and a clip attached to the housing of the tape measure. A bracket is removably engaged to the tape measure. A clamp is attached to the bracket such that the clamp forms a closed loop and a marker is insertable into the clamp thereby facilitating the marker to mark a line on the work piece. Alight holder is pivotally attached to the bracket and a flashlight is insertable into the light holder thereby facilitating the flashlight to be pivotally retained on the bracket. In this way the flashlight can emit light onto the work piece when the flashlight is turned on. A pencil sharpener is attached to the bracket thereby facilitating the pencil sharpener to sharpen a pencil when the pencil is employed as the marker.
