Concealed door closers are found in most commercial building and serve a useful purpose in controlling the closure of exterior entrance doors. The correct placement and installation of a door closer presents an arduous challenge for an installer who is often faced with uneven surfaces upon an active construction site. The related art relies upon the use of plumb bobs attached to upper door frame components and measuring implements placed upon ground surfaces. The task is so difficult that special training is required and specialist in the art are often employed install door closers. The presently disclosed embodiments comprise a jig system allowing for one or two door closers to be correctly positioned without the use of external or hand held measuring implements. An optional laser mounting system vitiates the need to attach lasers to door closer spindles.

The present invention discloses a method for automatically detecting door or window faults, comprising the following steps: mounting a displacement sensor at at least one monitoring position of the door or window frame and leaf and/or door or window hardware to monitor a relative position change of the door or window frame and leaf and/or relative displacement of the hardware at said at least one monitoring position; and connecting the displacement sensor to a controller which judges whether the relative position change of the door or window frame and leaf and/or relative displacement of the hardware at said at least one monitoring position exceeds a displacement threshold, and thereby perform combined judgment for door or window faults. The present invention further discloses a mechanism for automatically detecting door or window faults. The present invention can automatically detect possible faults occurring during use of the door or window, and thereby eliminate hidden risks endangering the user and other persons' personal safety, and exhibit important social significance.

An apparatus for measuring operational characteristics of a motorized window assembly of a vehicle door panel includes a support frame, a first sensor connected to the frame, a second sensor, and a third sensor connected to the frame. The first sensor is configured to measure displacement of a window of the window assembly, the second sensor is configured to connect between a motor of the window assembly and a power supply to measure an amount of current supplied to the motor, and the third sensor is configured to measure a force applied to the window by the motor. The support frame includes a first fastening device for coupling the frame to the door panel, and a second fastening device for coupling to an upper portion of a window frame of the door panel. The support frame is removably coupleable to the door panel via said first and second fastening devices.
