A filter assembly including a rectangular inlet frame having a rectangular inlet opening, a rectangular outlet frame, a housing body being collapsible to have a flattened shipping state and an erect state, the collapsible housing body in the erect state being rectangular and interposed between the rectangular inlet frame and the rectangular outlet frame in an assembled state, and at least one filter having filter media installed in the rectangular inlet opening in generally sealing relation thereto and projecting from the inlet frame toward the outlet frame in the assembled state.

A solar air heating curtain for installation on the wall or eave of a building consisting of a sheet of flexible translucent or transparent film facing outward from the building and a sheet of flexible film facing inward toward the building with both films joined around the perimeter forming an interior air volume, with a flexible air permeable material, that is heated when exposed to solar energy, suspended between the films, and a fan to move air from outside; through an air inlet, through the interior air volume in close contact with the air permeable material, and through an air outlet.

A heating, ventilation, and air conditioning (HVAC) backpack for modular animal crate is disclosed. The HVAC is configured to provide a climate-controlled environment within the modular animal crate. The HVAC backpack includes a framework that supports the components of the HVAC unit and mounting to the modular crate. The HVAC backpack may include a control module with a touchscreen display to receive control inputs for operation of the HVAC unit and provide a visual display of conditions within the modular crate. One or more sensors carried by the HVAC backpack monitor air quality delivered to the modular animal crate. The control module may include alerting the user to conditions within the crate. A communications module allows for remote control operation of the HVAC backpack and receiving alerts to conditions within the modular crate.

An apparatus comprising an animal containment part with one or more openings, a cover part for entirely surrounding the containment part, said cover part being flexible and transparent and including means for entry of a gaseous therapeutic agent.

A soundproof dog kennel includes a housing with noise-dampening walls and a noise-dampening door for dog ingress/egress. One or more walls has a ventilation assembly with noise-dampening baffles that permits inflow of breathable air with dampened sound waves when the door is closed, featuring hollow corridors, an air intake end, and an exhaust end. Fans force air through the sound-dampening ventilation ducts to reduce ambient noise while removing stale air. The kennel is equipped with cameras, carbon dioxide sensors, and other safety and monitoring devices. A smartphone application enables remote monitoring through live camera feeds, real-time sensor data display, and remote control of kennel functions. The system can automatically open the door if air quality or temperature reaches predetermined thresholds. This kennel protects dogs from noise pollution sources like fireworks, engines, and airplane auxiliary power units, providing a safe, quiet, and remotely monitored space for dogs.

A ventilation valve (1; 101) for ventilation of a space for keeping animals or plants includes an opening-defining circumferential framework (3; 103) for mounting in a wall of that space, and a movable panel (5; 105). The panel (5; 105) is movably attached to the circumferential framework (3; 103) to allow it to be moved relative thereto between a fully closed position, in which substantially no ventilating air can pass between the circumferential framework and the panel, and a fully open position in which substantially the complete opening is available for passage of ventilating air. Provided on the circumferential framework (3; 103) is a profiled edge which in a range between the fully closed position and a predetermined partly opened position provides a non-linear relation between a passage opening for the ventilating air and an associated relative movement position, or opening position, of the panel (5; 105) relative to the circumferential framework (3; 103). Also provided is a ventilation system for ventilating a space for keeping animals or plants, having at least a single specimen of the ventilation valve and having means for carrying out the method steps of periodically determining parameters of inside air present in the space, and adjusting the opening position of the ventilation valve on the basis of the determined parameters of the inside air.

An animal containment and automatic release enclosure is disclosed featuring a unitary structure providing a secure interior space for animals. The enclosure incorporates ventilation apertures, enabling the animal to access fresh air for breathing and ventilation. Environmental sensors in wireless communication with a personal device continuously monitor the enclosure's conditions, ensuring the animal's well-being. Wirelessly controlled enclosure doors, operated by an electric enclosure door control device, provide convenient access to the enclosed animal. The system further integrates external sensors, such as a carbon monoxide sensor for monitoring external CO levels, a moisture detection pad sensor to identify liquid accidents, and a temperature sensor to regulate internal temperature. The enclosure is designed to cater to various environments, including those with potential carbon monoxide exposure, making it suitable for use in multiple settings. It can be employed by veterinarians, law enforcement personnel, military professionals, security experts, pet owners, and animals trained for specific tasks. Additionally, remote access is possible through a personal communication device.

A cat carrier includes a tray, and an enclosure formed of: a lower housing portion with an upper mating flange, and an upper housing portion with a lower mating flange. Protrusions on one mating flange slidably engage openings formed with respect to the other mating flange, to releasably couple the housings together without tools. Holes in each of the mating flanges align, when the housing portions are mated, and each aligned pair of holes receives a fastener to releasably secure the housing portions together. The holes on one flange transition into a keyed opening (e.g. a hexagonal-shaped opening) that receives a hex head of a bolt, to prevent rotation of the bolt when a wing nut is tightened onto the fastener, permitting final assembly without the use of tools. The protrusions create a gap between the flanges, forming a track, which receives/guides a flange of the base.

Light traps, panels for light traps, and accessory devices are shown and described. In one example, a trap comprises a plurality of panels defining waveforms for at least a portion. The waveforms may be spaced a distance D apart to define a plurality of non-linear air-passages for allowing an airflow (AF) into or out of the poultry house at a velocity (V). The waveforms may include a plurality of light deflective walls (LDWs) for increasing the light reduction factor (RFL). A rail and/or rail system may be included for securing panels within the light trap.

An animal enclosure with a wall assembly and a panel that is configured to couple to the wall assembly. The wall assembly includes a plurality of walls that are coupled together to define an interior space. The walls define an opening configured for fluid connection to a ventilation system. When the panel is coupled to the wall assembly, the panel divides the interior space into a vent space, which is in fluid communication with the opening, and a living space. A vent opening formed in the panel is configured to place the living space in fluid communication with the vent space. The panel may be removably coupled to the wall assembly. The panel may include a damper system for selectively opening and closing the vent opening.
