Abstract: A method detects body temperature. A first image, a second image, and a thermal image are received. The first image is calibrated with the second image using a calibration model to form a plurality of visible image layers. A distance layer is generated from the first image and the second image using a distance generation model. The thermal image is calibrated using the distance layer and a distance calibration model to form a thermal layer. A face location of a person in the first image is detected using a face detection model. A body temperature of the person at the face location is determined using the thermal layer. The body temperature is presented.

Abstract: A method detects and tracks weapons. A frame of a video is received from a camera. A weapon in the frame detected using a weapon detection model. The weapon from the frame is classified using a weapon match classifier. A weapon alert is generated in response to classifying the weapon. The video is presented in response to the weapon alert.

Abstract: A method classifies air particulate data. Air sensor data is received from an air sensor. The air sensor data comprises a particulate vector. A machine learning model generates output from the air sensor data using a machine learning model. A notification that uses the machine learning model output is transmitted by a control system.

Abstract: A liquid intake assembly includes a filter member having a shower ring for removing solids from the outside surface of the filter member. The shower ring has an annular portion surrounding the filter member and a plurality of nozzle members for directing pressurized fluid in streams adjacent to and generally parallel to the outside surface of the filter member. The streams generate currents in the suspension removing the solids from the outside surface of the filter member.

Abstract: A toilet seat hinge has elongated male connector portions provided with saw-toothed shaped upper and lower surfaces which are inserted in female openings in the rear surface of a soft toilet seat and a soft toilet seat cover. The male connector portions lockingly engage with lock lugs provided in a rigid molded bed plate in the seat and cover to prevent retention so that the hinge is permanently connected to the seat and cover following insertion of the male connector member. Another aspect of the invention resides in a novel molding method in which two movable mold components provide openings extending both vertically and horizontally in a molded item.

Abstract: A toilet has first and second hinges equidistantly spaced on opposite sides of a medial plane of the toilet with each hinge including a vertical hinge post having a horizontal pivot hole receiving a tubular pivot sleeve extending unitarily from a cover hinge body member with a pivot shaft of a seat hinge extending into the pivot sleeve for pivotal movement. The seat hinge and cover hinge each have outwardly extending spikes inserted in mounting bores in the seat and cover with the spikes having protrusions for retention in the mounting bores and being oriented at an acute angle to and flaring outwardly in reverse manner with respect to the medial plane with the post and hinge components being formed of fiberglass reinforced polypropylene.
