A template for determining a stretching ratio of a film sample of a film spanning a round bale includes a template body which has a supporting side and an oppositely arranged working side. The template body includes an outline edge defining a perimeter of a film sample. Two slots are formed in the template body for applying markings to the film, the two slots being arranged parallel to each other at a first distance. A contact marking is arranged on the working side of the template body. A scale for displaying the stretching ratio of the film sample is arranged on the working side at a predetermined distance from the contact marking.

A stud finder and template system are provided. The system has a template, and a stud finder. The template aligns with a corner of a window frame and has multiple evenly spaced holes. The stud finder has a housing, a handle, and a pin. A method of determining a location for a curtain bracket with the stud finder and template system is also provided. The template is positioned against a window frame. The stud finder is positioned against a hole in the template. The stud finder handle is depressed. A stud finder for use with a template is also provided. The stud finder has a front housing portion, a rear housing portion, an actuator handle, a pin, and a pin return spring.

The tool for placement of markings presents novel structures and features that allow for easy, fast and accurate installation of blinds and shades.

An embodiment of the invention is directed to an electronic caliper which combines positioning and measurement in one unit without the use of hydraulics for subsea use. In certain embodiments, several attachments can be affixed to accommodate a range of measurement tasks. In a preferred embodiment, one jaw is adjustable and the other, or opposing, jaw is fixed to a mounting structure. The jaws typically allow for the removal and replacement of other attachments. In another embodiment, the unit communicates to computer software for position control, precise indication and clamping for adjustment. In a preferred embodiment, computer software displays all feedback via laptop computer on surface. The caliper is maneuvered to a position proximate an object and used to measure a predetermined physical characteristic of the object. The measurement can be displayed using a computer with control software.

A metered track and stud framework erection method and system is disclosed. The system employs tracks which are metered to facilitate the rapid and accurate placement of studs between the tracks at equidistant spacing as required by conventional building codes and statutes. The studs are also metered or graduated, preferably in inches and centimeters, to facilitate the correct and appropriate placement of electrical outlets and plumbing avenues without costly errors. A method is disclosed for the proper use of the metered tracks and studs to efficiently and rapidly erect structure framework.

A facemask package integrated with a mask sizing ruler is disclosed. The package stores the masks of various sizes. The mask sizing ruler comprising a first measuring gauge element, a second measuring gauge element and one or more sizes indicated thereon. The sizes in the sizing ruler are determined by categorizing one or more precisely previously measured distance from at least two points on one or more human faces into one or more sizes based on at least one distance on one or more masks of one or more mask sizes. At least one distance on one or more masks of one or more mask sizes is proportional to the maximum vertical distance of the mask in unfolded state. A system and method for determining the sizes indicated on the mask ruler are also disclosed. The sizing ruler precisely indicates the size of the mask that most appropriate to a user as the sizes are categorized from real human face dimensions.

A product comprising a film proportioned to fit on a surface of a mirror and adapted to electrostatically adhere to the surface of the mirror; the film comprising calibrated markings calibrated to allow a subject to accurately reference body position and body movements in the mirror when the film is adhered to the surface of the mirror. A mirror comprising calibrated markings including measurement demarcations and calibrated to allow a subject to accurately reference and measure body movements.

A hand knife tool has alignment markings configured on its blade to help orientate the cutting edge of the knife tool across a workpiece to make a miter cut. A transverse axis is defined perpendicular to a substantially straight middle section of the cutting edge and bisecting the two faces of the knife blade. Each alignment marking is configured on the knife blade at an angle relative to the transverse axis. Each of the alignment markings visually delineate an alignment line substantially across the knife blade between the cutting edge and the blade back. When one of the alignment markings on the knife tool is aligned to the edge of a workpiece, it places the cutting edge of the knife tool across the workpiece at a substantially congruent angle. Then the knife can be pivoted upon its edge and then make a miter cut.
