Abstract: A laser leveling device having a suction mounting arrangement includes a housing and a mounting seal extending from the lower portion of the housing. The mounting seal cooperates with an attachment surface to define a suction mounting area therebetween. The suction mounting arrangement cooperates with the mounting seal to maintain the vacuum pressure seal in the suction mounting area. A laser light source mounted within the housing in a planar relationship relative to the attachment surface includes at least one diode projecting an alignment beam through an opening in the housing to denote a reference plane along the attachment surface.

Abstract: A modular tool assembly including a tool base configured to releasably secure a modular tool arrangement in a fixed relationship relative to a mounting surface. The tool base includes an upper housing portion and a lower housing portion having a mounting seal extending therefrom. The mounting seal cooperates with the mounting surface to define a vacuum pocket therebetween. A vacuum generating mechanism is configured to remove air from the vacuum pocket through an aperture in the lower housing portion. A modular tool attachment releasably engages a portion of the tool base to secure the modular tool attachment to the tool base.

Abstract: An automatic, water dispensing, filter shutoff device having a disposable and replaceable filter. The shutoff device is in removable engagement and fluid communication with a water container such as a water bottle, and is adapted to disable dispensing after a predetermined amount of dispensing has occurred, which may but need not substantially correspond to the filtration capacity of the filter. In a preferred embodiment, the shutoff device includes a monitoring and disabling with plunger components moveable between dispensing and disabling locations, and a rotating indexing mechanism. At the disabling location, a plunger component is placed in an interfering position with the engagement between the shutoff device and the water container. The shutoff device can distinguish between water bottles having different volumetric capacities, and terminate dispensing accordingly. Preferable, a replaceable filter cartridge is provided which, when removed, causes the indexing mechanism to be reset.
