SURACE SURVEILANCE BY UNMANNED AERIAL VEHICLES
Videography of surfaces and improved positional control of unmanned aerial vehicles (UAV) are disclosed. Embodiments include defining a plane relative a vertical or semi-vertical surface. Linearly scanning along a line parallel to the plane. The plane being defined by three non-colinear points. The linear scanning along the plane is defined by a defined distance from the plane to the surface. The scanning including distance sensor scanning. The distance sensor scanning creating a model of the surface. The distance sensor scanning can include sound-based or light-based distance measurement scanning. The surveillance scanning can further include capture of imagery of the surface along the linear scanning along the plane.
FORMS FOR CONSTRUCTING FOUNDATIONS FOR ANCHORING POLE VAULT STANDARDS
A form for constructing a foundation for anchoring a pole vault standard to a support structure adjacent to a landing pad includes a first frame and a first plurality of connectors defining a first connecting pattern for coupling to a corresponding connecting pattern of a base of the first pole vault standard. The form is installable in the support structure and operable for use in fixedly connecting the first base of the pole vault standard to the form. A pair of forms may be employed for constructing a pair of foundations for anchoring a pair of pole vault standards to a support structure adjacent to a landing pad.
Cover assemblies for use in covering a sand area of a jump pit
A cover assembly may include a housing and an elongated cover. The housing defines a chamber therein. The chamber is disposable in the ground adjacent to a side of the sand area of the jump pit. The elongated cover has a first end, a second end, and spaced-apart sides extending from the first end to the second end. The elongated cover is storable in a compacted configuration in the chamber of the housing below the surface of the ground, and the elongated cover is removable from the chamber and extendable in an uncompacted configuration over the sand area of the jump pit to conceal the sand area.
Pole vault pit construction
A pole vault pit construction that is formed of multiple resilient foam blocks that are secured in a unitary manner and wherein thee construction is comprised of a front cutout section defining a recess for receiving a pole engager, said front cutout section having an open front end and an inner end, and a contiguous rear landing section. The plurality of foam blocks of the front cutout section include at least one pair of opposed position blocks each having a tapered surface commencing from the upper surface downwardly to the lower surface and in a direction toward the opposed position block so that a cross-section of the recess is essentially trapezoidal. The rear landing section includes at least a center foam block having an uninterrupted tapered surface commencing from the upper surface downwardly to the lower surface and in a direction toward the open front end of the recess.

Low vibration and noise reduction exercise mat unit
A low vibration and noise reduction exercise mat unit has a buffer plate and multiple protruding portions. The buffer plate has a board, multiple male buckles, and multiple female buckles. The board is quadrilateral and has a bottom, a recess, and a flange. The recess is formed on a bottom surface of the board. The flange is formed around the recess. The multiple protruding portions are disposed at spaced intervals in the recess of the board. The multiple protruding portions protrude downwardly from an inner top surface of the recess of the board. The buffer plate and the multiple protruding portions are made of natural rubber, will not affect the human body, and are stable in quality. The male buckles and female buckles can enhance the connecting strength between the mat units.

Unmanned aerial vehicles, videography, and control methods
Videography of surfaces and improved positional control of unmanned aerial vehicles (UAV) are disclosed. Embodiments include a panning piloting scenario. The panning can include control parameters relative to a normal vector to a point P of a plane representing a surface, or relative to a direction of gravity and attributes of the surface. For example, the UAV can be programmed, or controlled, to pan about the point on the plane maintaining a certain distance therefrom while rotating about angles to the normal vector. Methods of estimating a surface include determining a plane including three non-collinear points of the surface. The plane determined can be relative to the direction of gravity, such as vertically parallel to gravity. A piloting routine can include piloting a UAV to various angles relative to the vector normal to the plane and distances to the location on the surface and/or point on the plane.
