Abstract: According to an aspect of this disclosure, a ventilation and lighting system including a main housing having an inlet opening and a discharge opening, a blower and motor assembly disposed within a housing and operable to move air through the inlet and outlet, a grille configured to be located at the inlet opening, the grille having a cavity and a plate defining a plurality of apertures through which air may move, and one or more lighting elements arranged within the cavity and an optical component covering the cavity. The system is arranged such that light developed by the one or more lighting elements mixes within the cavity and transmits through the optical component covering the cavity, and the system further includes a controller that coordinates operation of the blower and motor assembly and the one or more lighting elements from a remote location.

Abstract: A ventilation and lighting system having a fan, a grille having one or more lighting elements and a controller that coordinates operation of the fan and the one or more lighting elements from a remote location. The controller defines scene control configured to define one or more scenes, each of which defines a predefined light control and fan control. The light control can have predefined settings of color, duration, intensity, saturation, and/or correlated color temperature. The fan control can have predefined settings of duration and/or power.

Abstract: The present disclosure relates to a system and method for monitoring and reporting the energy consumption of an appliance or fixture installed within a building structure. More particularly, the present disclosure relates to a system and method for monitoring usage of a ventilation unit, such as an installed bathroom exhaust fan or cooktop/range ventilation hood. The system and method captures usage data of the ventilation unit, and transfers the usage data to a connected electronic device for determining the energy consumed by the ventilation unit and reporting the same to a user.

Abstract: A simple, inexpensive ratchet type latch mechanism for maintaining a movable portion of an articulated structure in an elevated position relative to a stationary portion of the structure on which the movable portion is pivotably mounted. The latch mechanism includes a ratchet plate pivotally mounted at one end thereof to the stationary portion of the structure and has an elongate ratchet slot with a plurality of ratchet notches, an escapement plate slidably mounted to the ratchet plate for movement between a first position wherein the ratchet notches are exposed, and a second position wherein the ratchet notches are covered. A crank arm is pivotally connected at one end to the movable portion of the structure and has a pin at another end thereof which projects from the crank and through the slot in the ratchet and through the slot in the escapement plate.

Abstract: A screw drive mechanism for articulated beds and the like includes a drive shaft having external screw threads, a segmented drive nut having internal threads which engage the external threads of the shaft and a drive member in which the segmented drive nut is retained. At least one spring clip is disposed radially between the segmented drive nut and the drive member and engages the same to axially position and retain the drive nut in the drive member. The arrangement provides a simpler, less expensive drive screw mechanism which can be snapped together without tools and which can be easily disassembled for servicing.
