Abstract: An example air purification system comprises: an air guiding funnel; a particle absorbing filter disposed at an intake side of the air guiding funnel; a tangential fan disposed at an outlet side of the air guiding funnel; and an ultra-violet (UV) energy absorbing shell mechanically coupled to an discharge side of the tangential fan.

Abstract: Systems and methods for lighting fixture grouping and configuration in a distributed lighting system equipped with a wireless lighting network. An example method comprises: receiving, via a graphical user interface (GUI) rendered by a lighting network management application of a distributed lighting system, a command to associate a lighting fixture with a lighting fixture group; transmitting, to the lighting fixture, an update command specifying an identifier of the lighting fixture group and a value of a fixture configuration parameter; receiving, from the lighting fixture, an acknowledgement of the update command; incrementing a counter of lighting fixtures associated with the lighting fixture group; and displaying the counter in a visual association with a GUI element representing the lighting fixture group.

Abstract: An example method of attaching a printed circuit board (PCB) to a heat exchanger comprises: providing a heat exchanger comprising a base plate and two ridges attached to the base plate, wherein the ridges form a splayed channel; placing a printed circuit board (PCB) into the splayed channel; and squeezing the ridges of the splayed channel towards a longitudinal axis of the splayed channel.

Abstract: A lighting enclosure protected against water and dust is described. An example lighting enclosure comprises: a first elongated part comprising a longitudinal groove element; a second elongated part attached to the first elongated part, wherein the second elongated part comprises an outwardly bent longitudinal edge element engaged with the longitudinal groove element; a linear gasket inserted in a gap between the longitudinal groove element and the outwardly bent longitudinal edge element; and a compression strip inserted between a base of the outwardly bent longitudinal edge element and a longitudinal overhanging element of the first elongated part.

Abstract: A method, system, transmitter, receiver and protocol are disclosed for communicating with wireless receivers. The invention includes providing a controller having a discovery mode and an operating mode, in the discovery mode the controller is capable of registering wireless devices, in the operating mode the controller is capable of receiving transmissions from a wireless device that has been registered. A wireless transmitter is provided which is capable of communicating wirelessly with the controller. The wireless device has an actuator for initiating at least one transmission of registration data. When the controller is placed into the discovery mode, and the actuator of the wireless device is actuated to wirelessly transmit the registration data from the wireless device to the controller, whereby the wireless device is registered with the controller. The wireless data contains data that allows the controller to interface with the wireless device.
