An unmanned aerial vehicle (“UAV”) system for fluid transport includes a UAV having a fluid chamber configured to transport a fluid, a processor, and a memory. The memory includes instructions which, when executed by the processor, may cause the system to receive a first location for collecting or releasing a fluid, determine a fluid level of the fluid chamber, and transport the fluid by the UAV to the first location based on the determined fluid level.

An example fire suppression apparatus includes a nozzle assembly configured to emit a spray of water through a spray nozzle projecting outward from a side wall of the nozzle assembly. The nozzle assembly includes a union fitting body, a first compression nut threadably engaged with a first end of the side wall, a second compression nut threadably engaged with an opposite, second end, and a longitudinal aperture extending from the first end to the second end. A spray nozzle rotatably connected to the side wall is formed with a transverse spray channel in fluid communication with the longitudinal aperture. An apparatus embodiment optionally includes many of the nozzle assembly connected in series to one another by intervening water distribution pipes to form a water distribution network.

Collapsible insulated covers for devices (e.g., fire sprinklers) are contemplated. The collapsible insulated covers have one or more couplers configured to couple a device. The collapsible insulated covers collapse to thereby position the one or more to couple the device. It is contemplated that the collapsible insulated covers can create one or more seals that reduce heat transfer into its interior space (i.e., pocket) where the device or a portion of the device is placed for thermal insulation.

A sprinkler includes a frame, a deflector member, a sealing assembly, and a releasing mechanism for a controlled actuation. The releasing mechanism includes a hook member, a strut member, a load member, a link member, and an actuator. The link member surrounds or frames the strut and hook members and holds the members in a static relationship of an unactuated configuration. A preferred link member includes a single central slot through which each of the hook member and the strut member extend. The actuator is arranged with respect to the link member to separate the hook and strut members and break the link member upon operation of the actuator.

A fire exposure protection sprinkler assembly provides fire exposure protection for one or more windows and includes a fire exposure protection sprinkler, a sealing assembly configured to unseal in response to a fire such that fire exposure protection fluid may flow from the fire exposure protection sprinkler, and a housing having a pair of legs, with each of the legs having an aperture. The assembly also includes a deflection assembly configured to extend from the housing due to gravity and activation of a cover plate, with a deflector configured to disperse the fire exposure protection fluid over the one or more windows so as to wet the one or more windows.
