The present invention is directed to a marking device that includes a main backplate. At the center of the marking device there may be a central hole, and attached to the backplate, are two extendable arms, each designed with a pin attachment to make marks and/or small holes in the wall material. The extendable arms are attached to the backplate in a manner that the arm pin attachments on each arm are perfectly aligned with the central hole. Using a set of gears or other method, the extendable arms are fitted to the back plate in a manner whereby the extension and/or retraction of one arm causes the other arm to move in an equal, but opposite manner. With this, the holes and/or marks will be equidistant from the central hole/pin hole, and also in-line with the center hole/pin hole and each other.

The present invention relates generally to an apparatus for mounting and leveling a camera on a stand.The Arca-Swiss style (or arca-type) plate is a widely used type of quick-release camera plate for use on tripod heads. The typical arca-type plate is machined aluminum which attaches to the bottom of a camera via a ¼-20 screw and measures 38 mm wide with a 45 degree dovetail at the back of the plate.The plate interacts with an arca-type clamp which sits on top of a tripod head. The clamps work by moving a dovetailed rail in and out of the clamp body with either a screw knob or a lever to clamp down on the plate. This arrangement is considered a quick release as opposed to prior designs in which the cameras themselves were attached directly to the tripod head, which requires more effort to attach and remove.Bubble levels may be used by photographers to line up shots in either landscape or portrait compositions. The bubble levels may be horizontal, vertical, or a bull's eye configuration.Bubble levels ...

A traverse-type measurement method for a dual-system bilateral-survey composite level (A, B) is an intelligent traverse-type measurement method for integrated three-level error control loop inspection with the dual-system bilateral survey compound level (A, B). Specifically, survey station single-instrument inspection, survey station dual-instrument cross-inspection, and multi-survey station dual-instrument cumulative cross-inspection are adopted, and the number of observations and distance between survey stations are adjusted, such that measurement error is dynamically controlled in real time, ensuring that height difference measurement of survey stations and of measurement sections meets a preset precision requirement regardless of location or time, avoiding the invalid measurements that frequently occur with traditional levels, and improving working efficiency and economic benefit of the composite level. 1Step 1: measuring instrument parameter information;Step 2: determining start and end measurement points of a measurement section, and placing a composite level A at the start measurement point;Step 3: placing instruments and establishing survey stations;Step 4: setting an initial number of observations;Step 5: separately observing readings on the composite level A and a composite level B according to the set number of observations, and separately calculating errors of the readings;Step 6: determining whether the errors of the readings exceed a limit,{'sub': k', '0', 'k', '0, 'wherein if the errors do not exceed the limit, Step 7 is performed; if any error exceeds the limit, the number of observations is increased and it is determined whether the number of observations exceeds a threshold M; if the number of observations does not exceed M, Step 5 is performed again, and if the number of observations exceeds M, a front measurement point is moved to reduce a survey station distance, and then it is determined whether the survey station distance Dis less than a ...
