There is provided a biogas flux chamber constructed in one embodiment from a metal can with an open bottom and an epoxy interior coating. The chamber is inserted into the soil to allow influx of soil gases. The lid includes a sampling septum and a vent tube to prevent pressure build-up when the lid is in place which allows for an increase in interior gas concentrations. The rubber sampling septum is installed in a hole in the lid. The vent tube is constructed using flexible copper tubing inserted through the lid and secured using a bulkhead-fitting, and rubber O-ring to seal the insertion hole. The copper tubing is bent to form a double-curved ‘C’ shape which positions the open ends of the tube above and below the lid surfaces.

An animal sorting device comprising a housing having an entrance, an exit, and an animal dispatch chamber. The animal dispatch chamber comprises entrant assessment means to determine if an entrant is either a pest or a non-pest, animal dispatching means to dispatch the pest, and means to urge either a dispatched pest towards an aperture or the non-pest towards the exit. A modular animal sorting device is also disclosed.

An electronic rodent trap and monitoring method is provided. Each trap has at least one entrance, and preferably two entrances in opposed relationship to create a longitudinal tunnel, with a pair of lower plates extending longitudinally and oriented in spaced substantially parallel relationship, and a triggering element, such as a third plate, positioned above the lower plates, and preferably adjacent the ceiling of the trap on a center baffle that also shields a bait cup. The trap is activated when the rodent, with its left and right feet on the parallel lower plates, which are preferably raised above the floor, contacts the triggering element on the center baffle. The trap is preferably modular in design with an electronics module and a tunnel module removably secured within and protected by an outer housing. The trap also has improved features for more accurate remote monitoring of rodent dispatch and kill verification.

An electromechanical trap for small animals having a container attached to a module whose upper side is a swing frame which includes a solar panel. The module includes a tunnel with an open end and an access to let the animals to be caught enter and the floor includes a first fixed part, a second part, which has a missing section which coincides with the cutting on the module floor and a third fixed part where there is an appropriate vessel for the bait. First part and missing section of the second part have a tilting lamina as of at least an axis connected to the side ends of the tunnel. The tunnel has several sensors which generate a beam whose interruption sends a signal captured by the microprocessor enabling a single exit, energizing the coil which, during a programmed time equals the polarity of the permanent magnet freeing the lamina whose end, as the result of the animal weight, goes violently down tilting over the axis and lifting the opposite end in an equal or higher angle of 45 degrees.

An apparatus for controlling animal pests comprises a housing having a passage extending into the housing from an entrance, an impacting member movable across the passage and a planar sensor spaced apart from the kill bar by a predetermined distance along the passage towards the entrance, the planar sensor configured to sense the presence of the animal pest across a sensing plane across the passage wherein the impacting member is operable to be released to rapidly move across the passage when the planar sensor indicates the presence of the animal pest as passed through the sensing plane.

Described herein is a deterrence system for deterring animals from a vicinity of an environment monitoring apparatus, the system includes: a detector system having at least one sensor configured to generate a presence signal indicative of the presence of an object within a predefined vicinity of the environment monitoring apparatus; a deterrence processing system; and a repulsion system, wherein the deterrence processing system is configured to: monitor the presence signal; determine, from the presence signal, the presence of an object within the predefined vicinity of the environment monitoring apparatus; and communicate a command for the repulsion system to perform a sequence of one or more repulsion events actions in response to determining that an object is present, and wherein the repulsion system is configured to: perform one or more repulsion events responsive to receipt of the command from the deterrence processing system.

An automated system for mitigating risk from a wind turbine includes a plurality of optical imaging sensors. A controller receives and analyzes images from the optical imaging sensors to automatically send a signal to curtail operation of the wind turbine to a predetermined risk mitigating level when the controller determines from images received from the optical imaging sensors that an airborne animal is at risk from the wind turbine.

A sound detector system has one or more microphone positioned with a field of regard of 360°. The system further has a processor to translate a sound into data indicative of a direction and transmit the data indicative of direction. Additionally, the system has a handheld device configured to wirelessly receive the data indicative of the direction and display data identifying the field of direction to a user.

An automated system for mitigating risk from a wind farm. The automated system may include an array of a plurality of image capturing devices independently mounted in a wind farm. The array may include a plurality of low resolution cameras and at least one high resolution camera. The plurality of low resolution cameras may be interconnected and may detect a spherical field surrounding the wind farm. A server is in communication with the array of image capturing devices. The server may automatically analyze images to classify an airborne object captured by the array of image capturing devices in response to receiving the images.

Embodiments of the present invention provide a novel deterrent barrier based on the phenomenon of fluid cavitation. A drive unit comprising a motor and a propeller are configured for inducing cavitation in water. The cavitation takes the form of a rotationally confined vertical column of cavitation bubbles extending from the propeller, and a one-dimensional series of drive units spanning the width of a waterway may provide an effective, environmentally friendly and non-lethal barrier against entry of target fish species.
