A vehicle safety device for detecting vehicle tilt automatically shuts-off power to an ignition system and fuel pump and summons emergency assistance using a bistable switch circuit that toggles between a first bistable switch position in response to a reset signal and a second bistable switch position in response to an alert signal. The safety device can remain in the bistable switch positions without a power source and employ an encrypted bi-directional protocol to summon emergency assistance and generate the reset signal without vehicle operator intervention.

A panel installation assist device for supporting one end of a panel during installation includes a bar, which has a set of holes extending therethrough from a first face thereof. Respective holes are selectively alignable with studs or rafters. Mounting hardware inserted through the holes mounts the bar to the studs or the rafters. The bar has a set of orifices positioned therethrough, each of which has a spirit bubble tube positioned therein, which is engaged to the bar. Respective spirit bubble tubes indicate an orientation of a longitudinal axis of the bar relative to horizontal and vertical. A notch extends into the bar from a first edge thereof and the first face, and between opposed ends of the bar. The notch is configured for insertion of an edge of a panel so that one end of the panel is supported by the bar to facilitate installation of the panel.

An extendible or adjustable length level is provided. The level includes a frame, a slidable member, and a bushing. The slidable member is coupled to the frame and extends and retracts along the frame. The bushing is coupled to one of the frame or the slidable member and couples the frame and slidable member together.

Devices, systems and methods for hanging one or more objects, such as frames, on a surface. A marking device for marking a surface for hanging one or more objects. The marking device can have a main body portion having first and second arms pivotably attached thereto. The first and second arms, as well as the main body, can each have a marker to mark a target surface. The marking device can optionally have a level indicator and the first and second arms can have markers which can slide along a ruled measure for convenient positioning of marks on the target surface. Optionally, the markers can have biased, retractable, or sheathed marker pins.

This unique and novel invention provides a telescoping level device used to effectively and efficiently measure the slope of objects and surfaces. The device comprises a telescoping arm, a ball joint, a level, and one or more contactors. The device allows the user to easily, accurately, and quickly verify the in-situ slope of pipes as well as a plurality of other objects and surfaces. The length and angle of the telescoping arm, relative to the level, are adjustable to prevent the user from unnecessarily stooping, kneeling, or climbing.

A masonry level, with an extruded metallic box main body, is disclosed for measuring orientation of a work surface. The front of the main body includes an external longitudinal lower floating fin protrusion and a mid-section longitudinal tab and an upper longitudinal hook tab. The main body further includes an internal longitudinal tab in the back and multiple apertures for installation of eyelets for hanging the level, side bubble vials at the ends of the main body and a central horizontal bubble vial. The main body has a wider bottom relative to its top, and has a longitudinal upper back convex shape. A number of plastic claddings are attached to the front of the masonry level. Endcaps are attached to the ends of the main body structure. The masonry level can also be used as a construction tool to smooth uncured concrete and mud plaster surfaces.
