A foundation shift detection device includes a foundation portion attached to a foundation to be monitored, a base portion attached to a base adjacent to the foundation and supporting the same, and a rotary indicator attached to the base portion and adapted for rotation responsive to displacement of the foundation relative to the base. The rotary indicator is visible to a casual or walking inspection from a moderate distance, as by a human inspector making a walking inspection of a number of such devices.

A target and plumbing system includes a reflective target which has a reflective surface, a self-leveling plumb line laser pointer which emits a plumb line laser beam having a pathway that is in a vertical direction where the vertical direction is substantially parallel to a gravitational direction, a holding device which includes a first holding element that assists in holding the reflective target and a second holding element that assists in holding the plumb line laser pointer, and a positioning device which includes a first positioning element and a second positioning element where the holding device is connected to the first positioning element and the first positioning element is movable with respect to the second positioning element. The second positioning element is a platform including an open space that defines a horizontal two-dimensional area where the first positioning element is movable with respect to the open space.

A water line mapping assembly includes a remote unit that is held by a user. The remote unit has a remote transceiver that is in electrical communication with a global positioning system (gps). A capsule is provided that has an outside diameter sufficiently small to fit into a buried pipe. The capsule is comprised of a buoyant material to float in the buried pipe, and the capsule is comprised of a fluid impermeable material. A tracking unit is positioned inside the capsule and the tracking unit is in wireless electrical communication with the gps. Thus, the gps can establish a depth and a position of the tracking unit when the capsule is positioned in the buried pipe. The tracking unit is in electrical communication with the remote unit thereby facilitating the remote unit to display the depth and position of the tracking unit. In this way the remote unit can map the buried pipe.

A conduit laser alignment assembly includes a plurality of tubes that each has a unique diameter with respect to each other. A respective one of the tubes is positionable on an exposed end of an existing conduit in a building that has a diameter corresponding to the diameter of the respective tube. A laser emitter is removably coupled to the respective tube when the respective tube is positioned on the exposed end of the conduit. In this way the laser emitter can emit a beam of light that extends along a longitudinal axis of the existing conduit thereby facilitating the route of a new conduit to be displayed. An adapter disk is provided for coupling the laser emitter to a tube that has a greater diameter than the laser emitter.

Embodiments of the preset invention include a barcode reader that comprises a housing having a handgrip portion and an upper body portion, a first printed circuit board (PCB) extending into the upper body portion, and an imaging module positioned within the upper body portion. In this instance, the imaging module includes an imaging system having an imager and an imaging lens assembly, the imaging system having a field of view with a central imaging axis passing through a window in the upper body portion and lying on a horizontal plane. The imaging module further includes an aiming light system configured to emit an aiming light pattern, the aiming light system offset from the imaging system along the horizontal plane. Furthermore, the components of the barcode reader are arranged such that the first PCB is positioned at an oblique angle relative to the central imaging axis.

An optical alignment system is configured to determine lateral and longitudinal offset between a pump jack and a wellhead.
