Abstract: An anchor and shelter system is shown and described. In one embodiment, the anchor includes a pair of collapsible walls and opposing sidewalls to define a bladder opening. The anchor may include a plurality of parallel engagement apertures and side apertures to secure the anchor to a shelter. The result is an anchor that provides efficient and secure support for an adjacent shelter.

Abstract: An apparatus and method of automatically determining an operating frequency of a scanning probe microscope such as an atomic force microscope (AFM) is shown. The operating frequency is not selected based on a peak of the amplitude response of the probe when swept over a range of frequencies; rather, the operating frequency is selected using only peak data corresponding to a TIDPS curve.

Abstract: In one exemplary embodiment, a power tool assembly includes a percussive power tool having a cutting tool with a cutting edge; a vacuum source; and a dust suppression boot for attachment to the power tool and vacuum source in such a way that unwanted foreign matter, such as dust, particles, etc., that is generated when a work surface (e.g., concrete surface) is broken apart is collected and evacuated from the work space through the boot. This results in a much cleaner and safer work environment, as well as substantially reducing the preparation time and cleanup times, as well as reducing overall costs.
