Abstract: An electrical device configured to install within a wall mounted electrical box includes an antenna bezel frame, an antenna element, and a radio frequency circuitry component. At least a portion of the antenna bezel frame is configured to protrude through an opening in a faceplate. The antenna element is mounted to the antenna bezel frame such that the antenna element is located a distance forward of a plane that contains a front surface of the faceplate when the field configurable electrical device is installed. The radio frequency circuitry component is in electrical communication with the antenna element and is configured to receive a control signal from the antenna element.

Abstract: A lighting dimmer (52) adaptable to four wiring configurations is capable of use in serial or parallel lighting circuits and in place of two-way or three-way switches. The dimmer operates in series when one active input wire (H) is connected and in parallel when two active input wires (H, N) are connected. The dimmer is operated in place of a two-way switch by connecting one output wire (DH1) and in place of a three-way switch by connecting two output wires (DH1, DH2).
Abstract: A portable RF wireless device (41), such as a microphone, is provided with an infrared beacon in order to signal a connection request to a wireless communication access point (48) using a first IR code (401). In response to this first IR code, the wireless communication access point broadcasts an RF inquiry message (101) that is responded (102) to by the portable RF wireless device in order to establish an RF communication link. After the RF communication link is established, the portable RF wireless device conditionally transmits a second IR code to verify that it is still collocated in the local vicinity of the wireless communication access point, such as being in the same room.

Abstract: A high pressure water injection humidifier includes a filtration system (11) to filter an incoming water supply and provide filtered water (6) to a low volume high pressure pump (12) driven by a constant speed motor (13), which in turn provides pressurized water (7) to a plurality of exit nozzles (17), each exit nozzle having a precision orifice that atomizes the pressurized water into a mist, where the volume rate of the mist is dependent only on the motor speed and the diameter of the precision orifice.
