Abstract: An unmanned aerial vehicle (UAV) for transporting items between locations includes a frame and a propulsion system coupled to the frame, the propulsion system including at least one transmission and at least one motor. The UAV also includes a load support area of the frame, the load support area comprising at least one of a different material than the frame or structural supports.

Abstract: A fenestration wall assembly includes a fenestration frame extending along a perimeter of the fenestration wall assembly. The fenestration frame includes a socket core having a first module socket configured to interchangeably receive service modules therein, and a second module socket configured to interchangeably receive service modules therein. The interchangeably received service modules include at least first and second service modules. Each of the first and second modules includes respective first and second module profiles. A panel having a panel profile is surrounded by the fenestration frame. The panel profile is isolated from the first and second module profiles.

Abstract: A sanitation apparatus for cleaning a conveyer belt, having a housing; a float in a float chamber; a liquid reservoir; a liquid cleaning solution dispenser holding liquid cleaning solution and positioned above the housing; a tube dispensing the liquid cleaning solution into the float chamber, cleaning elements associated with the housing via a first set of compressible elements biasing the cleaning elements against the conveyer belt; a cylindrical roller connected to the housing via a second set of compressible elements biasing the cylindrical roller against the conveyer belt; the cylindrical roller being contained in the liquid reservoir such that a first portion is exposed to the liquid cleaning solution, and a second portion is in contact with the conveyer belt, engaging the cylindrical roller with the conveyer belt to cause transfer of a movement of the conveyer belt to the cylindrical roller and rotating the cylindrical roller.
