Systems and methods are disclosed that operate a door latch of a door of a heating, ventilation, and/or air conditioning (HVAC) system electronically based on operating a locking engagement device. The locking engagement device may be disposed on an outer portion of a door, the latch may be part of a latching system disposed on an inner portion of the door, and the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to the latching system via a conductor electronically coupling the locking engagement device and the latching system. In some embodiments, the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to a controller, which may then instruct the latching system to open or close the latch based on receiving the signal.

A computer-implemented method for anomaly detection in a data processing system comprising a processor and a memory comprising instructions which are executed by the processor. The method includes receiving a plurality of real-time airflow patterns acquired by a plurality of airflow alerters, wherein each real-time airflow pattern corresponds to a different airflow alerter; comparing each real-time airflow pattern with a predetermined airflow pattern, wherein each real-time airflow pattern corresponds to a different predetermined airflow pattern; when there is any real-time airflow pattern different from the corresponding predetermined airflow pattern, identifying a group of airflow alerters among the plurality of airflow alerters, wherein a real-time airflow pattern of each airflow alerter in the group is different from the corresponding predetermined airflow pattern; and identifying a location of an anomaly based on the group of airflow alerters.

A computer-implemented method for anomaly detection in a data processing system comprising a processor and a memory comprising instructions which are executed by the processor, the method including: receiving, by the processor, a real-time airflow pattern detected from an airflow alerter, wherein the real-time airflow pattern is generated by a heating, ventilation, and air conditioning (HVAC) system in a particular facility; comparing, by the processor, the real-time airflow pattern to a predetermined airflow pattern for the HVAC system; and when the real-time airflow pattern is different from the predetermined airflow pattern, receiving, by the processor, an alert message indicating an anomaly from the airflow alerter.

A box which is expandable vertically and horizontally is disclosed. The box can be expanded both vertically and horizontally simultaneously, or in only one of these directions. This is accomplished by pulling/pushing opposite sides further/closer to each other. Rails which at least partially extend between respective opposite sides allow such an expansion/or contraction, the rails, in embodiments, having a pin of one section of the box held within a slot of an adjacent section of the box. The box, in embodiments, is made up of four separate pieces, each being one quadrant (top & left, top & right, bottom & left, bottom & right) of the box. Such a box can be expanded/collapsed to fit within a window and hold an air conditioner there-in.

According to one embodiment, an outdoor unit equipped with a communication unit and a controller. The communication unit communicates data in a noncontact manner to an information terminal close to the outdoor unit. The controller permits the setting of data that has been input from the information terminal via the communication unit only during a fixed period of time after the outdoor unit has been turned on.

A system that screens for particularly identified odors, such as those associated with explosive and other bomb-making materials, weapons and illegal drugs, includes an odor delivery unit with one or more fans that force air across the object being screened, such as a person. The airflow from the odor delivery unit passes over and across the object being screened creating an odor stream that passes through a partition that allows the odor stream to flow freely through it and simultaneously obscures a canine positioned on the other side of the partition from view by the person or object being screened.

A vent cover apparatus for protecting vents, air conditioners, and skylights includes a cover body having a body front side, a body back side, a body left side, a body right side, a body top side, and an open body bottom side. The body bottom side is configured to receive a vent, an air conditioner, or a skylight on a roof of a recreational vehicle or a building. The cover body is rigid and allows for full air flow through the cover body. A plurality of mounting braces is coupled to the cover body. Each mounting brace is coupled adjacent the body bottom side and configured to engage the roof of the vehicle.

A security sleeve including a top panel, a bottom panel, two side panels, a first end, and a second end. The first end of the security sleeve is open and the second end is at least partially closed by at least one bar and the at least one bar is secured to the second end. The security sleeve can be installed in the opening of a wall or panel, e.g., in a shipping container. An air conditioning unit or a heating unit can be installed in the security sleeve through the first end.

A system for selectively opening and closing a ventilation opening in a window glass panel. The system includes a shield gasket and a ring-shaped fixing frame inserted into the opening, with the gasket interposed between the opening and the fixing frame. A cover is inserted into the fixing frame to open and close the ventilation opening. Fixing frame alternatives include wherein the fixing frame comprises a drain structure, an exterior gutter, a filter, and peripheral elastic support hooks. Shield gasket alternatives include wherein a body part transforms into a cylindrical shape during installation of the fixing frame, and wherein a wall part comprises a circumferential elastic protruding part forming an inner space part therein. Cover alternatives include wherein the cover includes ring shaped shielding walls and a hook to engage fixing frame insertion groove.

A computer-implemented method for anomaly detection in a data processing system comprising a processor and a memory comprising instructions which are executed by the processor. The method includes receiving a plurality of real-time airflow patterns acquired by a plurality of airflow alerters, wherein each real-time airflow pattern corresponds to a different airflow alerter; comparing each real-time airflow pattern with a predetermined airflow pattern, wherein each real-time airflow pattern corresponds to a different predetermined airflow pattern; when there is any real-time airflow pattern different from the corresponding predetermined airflow pattern, identifying a group of airflow alerters among the plurality of airflow alerters, wherein a real-time airflow pattern of each airflow alerter in the group is different from the corresponding predetermined airflow pattern; and identifying a location of an anomaly based on the group of airflow alerters.
