Abstract: When extending the leader or tape from a traditional tape measure over a large distance, a user situated away from the body of the tape measure is unable to determine the length that has been extended at the leading edge. Presented herein is a retractable measuring device in which the body of the measuring device is configured to compute and broadcast the amount of tape that has been withdrawn from the body to a receiver. The receiver may be located at the leading edge of the tape or comprise a secondary device such as a smartphone. Alternatively, the broadcast may include tactile, audible, or visual feedback relating to the distance that may be received directly by the user. Additionally, the retractable device may include an interface for setting a desired length and provide either the user or receiver with feedback when the desired length has been reached.

Abstract: An example pool double safety cover has an upper cover substantially impermeable to water, and a lower cover substantially permeable to water. An example pool double safety cover has a first pulley system for the upper cover and a second pulley system for the lower cover. Each pulley system has first and second pulley wheels at one end of the pool and third and fourth pulley wheels at the opposite end of the pool. Rotating at least one of the pulley wheels causes all of the pulley wheels of the corresponding pulley system to move either a first line connected to the upper cover or a second line connected to the lower cover. An upper track guides the upper cover to open and close over a pool opening, and a lower track guides the lower cover to open and close over the pool opening.

Abstract: A plot measurement system which enables a user to singlehandedly mark boundaries and features of a sports field or construction site with improved accuracy. The system utilizes a plurality of vertex markers connected by measuring leaders to provide triangulation. A three-vertex marker system can be used to construct triangles, which can then be used to construct any n-sided shape. The concept is scalable and a four-vertex marker system is presented to quickly construct quadrangle plots such as an endzone. The disclosure presents mechanical and electrical systems.

Abstract: A water release valve is disclosed for a pool safety cover on a swimming pool. An example water release valve includes an upper valve body and a lower valve body. The lower valve body is attached to the upper valve body through an opening formed in the pool safety cover. A valve actuator is configured to automatically open to release at least some water on top of the pool safety cover into the swimming pool to reduce water accumulation on top of the pool safety cover. In an example, the valve actuator automatically opens under the weight of the water on top of the pool safety cover. In an example, more than one water release valve may be provided at various locations on the pool safety cover.
