A wildlife exclusion system for railway tracks is provided which includes an exclusion arrangement positioned to span across the railway tracks at a location along a length of the railway tracks. The exclusion arrangement extends generally perpendicular to the railway tracks and has a series of conductive elements spaced apart from each other to form an exclusion are configured to provide an electric shock to wild animals when particular conductive elements within the exclusion area are bridged thereby. Methods of installing a wildlife exclusion system and methods of discouraging wild animals from traveling along railway tracks are also provided.

An electric fence control unit includes a signal generator, a first signal receiver, a second signal receiver, a signal processing and control unit, and a communications interface. The signal generator generates and transmits an adjustable power signal along a conduction path of the electric fence. The signal receivers sample signal outputs at a driven end and at an open end of the fence line. The signal processing and control unit receives and analyzes the first signal output and the second signal output. The communications interface transmits results from processing the first signal output and the second signal output to a service center. The power signal is adjustable to any capacity power level between a maximum power level and a minimum power level to match a load of the electric fence. Methods of monitoring the electric fence, including adjusting a power level of the adjustable power signal, are also disclosed.

The present invention relates to moving animals to a new location. More particularly but not exclusively, it relates a wearable device to send a stimulus to guide an animal from an initial location to a target location, where the journey between the two locations comprises a path that the animal may be hesitant to transit, and adjusting the stimulus accordingly.

Described is a chondrichthyan repelling system comprising at least one fin comprising at least one electrically conductive electrode for connection to an electrical signal generator. In use, the electrical signal generator generates electrical signals to the at least one electrode to thereby radiate an electrical field which repels chondrichthyans. Also disclosed are various fin designs incorporating one or more electrodes, and a watercraft having one or more fins as described. Various means of connecting the electrodes to the electrical signal generator are also described.

An electric fence energizer provides automated reporting of faults and other events as well as fault location to reduce effort in diagnosing faults and intrusion events in electric fences by measuring impedance changes using a time-domain reflectometer. In some embodiments, methods determine the location of a fault in distance from the energizer and provide timely and appropriate condition information.

A fencing system for deterring an animal from entering a facility includes a control box, a fencing base controlled by the control box, and a conduit cable connecting the control box and the fencing base. The control box includes a power supply, a generator board, a transformer and a grid load resistance detector. The generator board produces electrical wave form transformed by the transformer. The transformer connects to two connection braces of the fencing base. The control box operates in an active mode and a halted mode depending the grid load resistance and duration of the load resistance. The fencing base includes a set of fence tracks forming the grid and connected to the connection braces in an alternating style. The control box also supports more than one fencing base. The more than one fencing base can take different shapes and be extended in length to fit facility openings of different sizes.
