A rodent barrier system is disclosed herein. The rodent barrier system includes a vehicle elevation platform, a perimeter ladder having a plurality of rungs, a right ramp, and a left ramp. The rodent barrier system is useful for deterring rodents from accessing a vehicle.

Disclosed is a method for guiding aquatic organisms. The method includes disposing a plurality of electrode units at a distance from one another in water; and applying an electrical pulse to at least one electrode unit of the plurality of electrode units to generate an electric field and/or a magnetic field around the at least one electrode unit to guide the aquatic organisms by stimulating the aquatic organisms with the generated electric and/or magnetic fields.

A pet location monitoring and deterrent system is provided. The system includes a first pet collar assembly that transmits a first RF signal. The system includes a first pillar assembly having a first control module, a first RF receiver module, an infrared photodetector array, a first wireless transceiver circuit, and a first warning light. The system includes a second pillar assembly having a second control module, a second RF receiver module, an infrared phototransmitter array, and a second wireless transceiver circuit. The first and second pillar assemblies are disposed a predetermined distance apart from one another such that a warning area is defined in front of and proximate to the first and second pillar assemblies and a keep-out area is defined behind and proximate to the first and second pillar assemblies.

An electrified feeder assembly includes a hopper, an actuator assembly, a motor, and at least one power supply. The hopper is configured to hold a quantity of feed wherein the feed is gravity fed downward through a feed tube. The actuator assembly is coupled to the hopper and is configured to selectively disperse feed when powered by the power supply. The motor receives power from the power supply and selectively spins the actuator assembly at a selected speed to open and close the feed tube. The speed of rotation induces a centrifugal force which opens the feed tube by translating the position of a portion of the actuator assembly. The feed exits the hopper through the feed tube and is dispersed through contact with the rotating actuator assembly. The actuator assembly is partially and temporarily electrified when manipulated in a closed position.
