Abstract: A lawn stake holder for holding multiple backyard items including drink glasses, cans, wine glasses, corn hole bags, and horseshoes. The lawn stake holder generally comprises a unitary holder formed by bending a metal rod into a U-shaped yoke at the center, and bending a substantially-rectangular platform on one side of the U-shaped yoke, leaving a horizontal strut on the other side of the U-shaped yoke. The unitary holder is supported by a unitary lawn stake component formed from a single elongate rod with a pointed lower tip at one end for insertion into the ground, and a circular metal eye at the other end bent around the U-shaped yoke of the holder component. The holder component may be welded to the lawn stake component to secure it in place.

Abstract: A plurality of positional sensing devices are situated at regular intervals within an environment and collect data for tracking objects moving within the environment. Phase shift of modulated Doppler pulses reflected from the sensing devices to objects are measured and converted into positional data indicating positions of detected objects within the environment. Associated timestamp data is also collected by the positional sensing devices. The positional data and associated timestamp data is aggregated from the plurality of positional sensors, and the aggregated positional data and is clustered to determine point clouds which are associated with the detected objects. The clusters are tracked by tracklets that track the position of each cluster over time. Trajectories for each detected object are determined by connecting tracklets together that are associated with the same detected object.

Abstract: A versatile lever-type decking and plank removal tool for more efficiently prying floor-boards from deck foundations and floor-joists to which they are nailed. The decking and plank removal tool uses an adjustable demolition head having an offset inverted hook to tear off any deck board in any configuration in seconds with a minimum of effort, allowing the user to remain completely upright for the entire process. An optional vibratory-assist module is also disclosed.

Abstract: An improved deck fastener removal tool comprising a fixture with an extended handle to hold the cutting blade of an angle grinder or like tool in plane with the top of the joist and removed a safe distance away from the operator's body. The handle may be extendable and adjustable to render it comfortable for use by multiple operators. The fixture utilizes a series of guards to ensure that the cutting blade remains level with the top of the joist along the entire length thereof, allowing the operator to walk steadily along the top of or next to the joist to quickly and safely remove each residual fastener protruding therefrom. An integrated collection tray automatically gathers the severed portions of the fasteners as they are cut.
