Abstract: A method including training, by one or more processors, a generative AI model using first operating data from building equipment and a plurality of first service reports indicating a plurality of first problems associated with the building equipment. The method may include predicting, by the one or more processors using the generative AI model, one or more future problems likely to occur with the building equipment based on second operating data from the building equipment. The method may include automatically initiating, by the one or more processors, one or more actions to prevent the one or more future problems from occurring or mitigate an effect of the one or more future problems.

Abstract: A method including training, by one or more processors, a generative AI model using a plurality of first service requests handled by technicians for servicing building equipment. The generative AI model may be trained to predict root causes of a plurality of first problems corresponding to the plurality of first service requests. The method may include receiving, by the one or more processors, a second service request for servicing building equipment. The method may include predicting, by the one or more processors using the generative AI model, a root cause of a second problem corresponding to the second service request based on characteristics of the second service request and one or more patterns or trends identified from the plurality of first service requests using the generative AI model.

Abstract: The present invention is a spotlight with adjustable focus that has a focus fixing mechanism to prevent inadvertent changes to the focus of the light, while still allowing user-friendly intentional adjustment of the focus. The mounting collar of the reflector assembly rotates on helical threads on the neck of the lamp assembly so that the focus of the light may be adjusted. The focus is fixed in position by a plurality of ridges and valleys on the lamp assembly that mate with corresponding ridges and valleys in the collar of the reflector assembly. The collar of the reflector assembly is sufficiently flexible or expandable so that the focus of the lamp may be intentionally changed by applying sufficient rotational force to the reflector assembly. The collar is sufficiently rigid that the reflector assembly will not rotate as a result of incidental vibrations or movement.

Abstract: An exhaust dispersion device for an exhaust system with an outer flow member is disclosed. The exhaust dispersion device includes a dispersion member capable of being disposed within the outer flow member. The dispersion member defines an axis and includes an upstream end and a downstream end. A cross section of the downstream end perpendicular to the axis is larger than a cross section of the upstream end perpendicular to the axis. The dispersion device also includes an aperture extending through the dispersion member. The aperture is coaxial with the axis. Flow of all exhaust gas through the outer flow member is divided between flow through the aperture and flow between the outer flow member and the dispersion member. The dispersion member is operable to divert the flow of the exhaust gas at least partially toward the outer flow member.
