A security system for preventing ungrounded personnel access into an equipotential zone is described. The security system includes a conductive fence and a conductive mat. The conductive mat is mechanically and electrically coupled to the conductive fence to define an equipotential zone.

A portable livestock corral features a central alleyway subdivided into two alleys and having two sets of foldable corral panels for forming livestock pens on opposing sides of the alleyway. On either side of the alleyway, a bud box is selectively deployable at a corner of the respective livestock pen that resides across from an openable/closable alleyway side-gate of the other pen, whereby loading of the alleyway from either pen can exploit such a bud box. Inside the alleyway, an internal swing gate is lockable in different positions to enable opening of both alleys, or selectively closure of either one of the two alleys, which can serve as a livestock-free zone safely occupiable of a human operator. In transport mode, a safety bar with deployable stops at its opposing ends mechanically restrains the folded-up corral panels on both sides of the alleyway for optimal road safety.

A cattle guard assembly includes a cattle guard that is positionable in a depression in a roadway extending along a fence line. In this way the cattle guard inhibits livestock from crossing the fence line in the roadway. The cattle guard is comprised of a resiliently compressible material thereby resisting impact damage. Additionally, the cattle guard is comprised of a non-oxidizing material to resist corrosion. The cattle guard comprises a plurality of modular units thereby facilitating the cattle guard to have a selectable width for accommodating a variety of roadway widths. Each of the modular units is comprised of a molded, unitary structure such that said modular units resist breaking. Each of the modular units includes a base and a grate, and the grate is positionable in an existing cattle guard base for replacing an existing grate in an existing cattle guard.

A tie out for restraining multiple animals includes a frame having a central post, and an axle arranged perpendicularly to the central post, wherein the axle is rotatable about a vertical axis defined by the central post. The tie out may further include a first reel mounted on the axle and rotatable about a horizontal axis defined by the axle, and a first cable that is wound on the first reel. The tie out may further include a second reel mounted on the axle and rotatable about the horizontal axis, and a second cable wound on the second reel, wherein the first reel rotates around the axle independently of the second reel. The tie out further includes a cable guide arranged between the first reel and the second reel, wherein the cable guide is configured to prevent the first cable or the second cable from becoming tangled on the tie out.

Disclosed is a pond culture circulation system based on a bio-toilet module including a culture pond and an annular treatment channel surrounding the culture pond. The annular treatment channel is sequentially provided with a sedimentation zone, a biological purification zone and a water storage zone along a direction of water flow. The culture pond includes a plurality of culture pond units. Each of the plurality of culture pond units is provided with a bio-toilet module in communication with the sedimentation zone through a sewage pipe. The water storage zone communicates with each of the plurality of culture pond units through a gravity-flow culvert. The invention further discloses a use method of the pond culture circulation system based on the bio-toilet module.

The Device for Supporting an Electrified Wire is a device for supporting an electrified elongate conductor on a fence or other structure, the device comprising: an insulating base for attaching said device to a fence or other structure, a spring connectively attached to said base, and an elongate member connectively attached to said spring positioned to extend away from said fence or other structure, wherein said spring is configured to deform elastically to allow the elongate member to move from an un-deflected position with a distal end laterally away from the fence or other structure to a deflected position towards the fence or other structure in at least a sideways direction upon application of a force lateral to the elongate member, and to spring back again to the un-deflected position once the force is removed. It is used to contain and alter the movement activity of livestock.

The device is comprised of two panels in the shape of “L”s that are interwoven with each other when they are placed on the sides of a fence. The device is secured to the ground through a series of holes for that purpose. Additionally, an expander has been placed on the section of the device, both vertical and horizontal, to address the issue of uneven terrain. A row of embedded lights is installed in each of the horizontal panels to provide additional illumination. Alternatively, a series of embedded wires may be installed in the horizontal panels that rest on the ground to provide a small (but not deadly) shock to prevent animals from entering the yard or preventing a family pet from leaving the yard.

A robotically controlled system including a fence enclosure that can move and/or shape-shift itself autonomously and automatically without manual intervention. The system includes coils of electric fence wire that are spring-loaded or otherwise tensioned so that the length of electric fence wire between each post robot is able to contract or expand as the system of robots adapts to optimize the shape of the fence enclosure as the entire enclosure is moved by the robots around a field or other grazing pasture on an area of land. At least one of the post robots is able to provide an earth ground connection that is movable as the fence enclosure is moved.

A circular grazing system for poultry and/or livestock. The circular grazing system including a center pivot structure installed at a field. The center pivot structure may have a center pivot axis. The field may be a poultry and/or livestock grazing field. The circular grazing system for poultry and/or livestock may include an enclosure for containing poultry and/or livestock. The enclosure may extend generally radially from the center pivot structure to a circumference of the field. The enclosure may be rotably coupled to the center pivot structure such that the enclosure rotates around the center pivot axis.
