A method of using the spraying device is also described.

A spraying device for spraying fluid from a replaceable refill is described wherein the refill possesses a refill body containing a reservoir of fluid to be sprayed, a valve stem in fluid communication with the reservoir and a spray head mounted on the valve stem, the spray head having an exit nozzle, wherein the spray device comprises:

a housing formed from an top portion and a base portion which are releasably connectable with each other through contact between engagement means on each portion, wherein the top portion comprises:
a cavity configured to house at least an top portion of the refill therein;
a top surface and an engagement surface having an top portion housing wall therebetween, wherein the top portion housing wall has a thickness;
an actuation mechanism configured, in use, to actuate the spray head to spray fluid via the exit nozzle;
a spray opening configured to permit, in use, sprayed fluid to exit the device into the surrounding environment;
and wherein the base portion comprises:
a cavity configured to house at least a base portion of the refill therein said cavity being defined by a cavity wall and a support platform configured, in use, to support the refill at a predefined position in the cavity;
the base portion being provided with an engagement surface and a bottom surface and a base portion housing wall therebetween;
wherein the base portion housing wall at least adjacent the bottom surface is spaced apart from the cavity wall by at least the predefined top housing wall thickness to define a top portion receiving channel;
and whereby the device facilitates an operational configuration wherein the top portion and the base portion of the housing are engaged with each other by their respective engagement means with the refill located within the respective cavities; and wherein the device facilitates a packaged configuration wherein at least the engagement means and at least a some of the top portion housing wall of the top portion are located within the top portion receiving channel.

A scenting device for scenting a vehicle interior may include at least one aromatic substance container holding a supply of an aromatic substance. The device may also include a feeding duct for feeding air to the at least one aromatic substance container and a discharge duct for discharging air enriched with the aromatic substance. The device may further include at least one scenting path for enriching air with the aromatic substance from the at least one aromatic substance container. The device may include a bypass duct branching off from the feeding duct and bypassing the at least one aromatic substance container. The device may also include a bypass valve and at least one container valve. The device may include a camshaft including a bypass cam configured to actuate the bypass valve and at least one container cam configured to actuate the at least one container valve.

An accessory for an unmanned aerial vehicle (UAV) comprising a baseplate that is attached to the UAV unmanned aerial vehicle, at least one dispersant canister that is removably attached to the baseplate, a radio frequency receiver, an auxiliary circuit board, at least one battery, first and second wire pairs that supply electrical current from the auxiliary circuit board, a protective housing, and a radio frequency transmitter that is in communication with the radio frequency receiver. In alternate embodiments, the invention further comprises an electric match, linear solenoid, or electric primer.

An automatic discharge device includes a housing having a recess for receipt of the body of a container and a groove configured to receive a portion of a valve stem of the container. The recess includes a tapered upper end configured to fit a neck of the container. Further, a first compartment for receipt of a first battery and a second compartment for receipt of a second battery are provided. An actuator is disposed proximate the groove, which defines lateral sidewalls and a rear sidewall and has an open forward end to receive the valve stem.

A system and method for remotely controlling behavior of multiple devices are presented. The system comprises a plurality of devices, e.g. puffers, and a remote master controller. Each device includes a radio frequency (RF) control system for programming and control of its operation. The communication between the puffer and the master controller during mass programming is through Bluetooth Low Energy peripheral mode and observer mode. Using its peripheral mode, the master controller advertises a desired program for the puffers in an orchard through a custom UUID. Each puffer picks up and parses the custom UUID and reprograms itself. Each puffer also uses its peripheral mode to advertise its configuration to be picked up by the master controller so that the master controller can verify that the puffer has correctly reprogrammed itself based on the mass programming advertisement.

A device for disinfecting, sterilizing and/or maintaining medical, especially dental, instruments comprises a maintenance and cleaning chamber for accommodating instruments to be conditioned and means for supplying different cleaning or maintenance media for cleaning, disinfecting or sterilizing and/or maintaining the instruments in subsequent steps.
