  2. Wireless light switch - Wikipedia

    en.wikipedia.org/wiki/Wireless_light_switch

    Dimmer light switch with RF-based remote control [1] A wireless light switch is a light switch that commands a light or home appliance to turn itself off or on, instead of interrupting the power line going to the light fixture. There are different ways to communicate between the switch and the fixture: [2]

  3. Radio-frequency microelectromechanical system - Wikipedia

    en.wikipedia.org/wiki/Radio-frequency_micro...

    The prior art includes an RF MEMS frequency tunable fractal antenna for the 0.1–6 GHz frequency range, [18] and the actual integration of RF MEMS switches on a self-similar Sierpinski gasket antenna to increase its number of resonant frequencies, extending its range to 8 GHz, 14 GHz and 25 GHz, [19] [20] an RF MEMS radiation pattern ...

  4. RF switch - Wikipedia

    en.wikipedia.org/wiki/RF_switch

    An RF switch or microwave switch is a device to route high frequency signals through transmission paths. RF ( radio frequency ) and microwave switches are used extensively in microwave test systems for signal routing between instruments and devices under test (DUT).

  6. Dimmer - Wikipedia

    en.wikipedia.org/wiki/Dimmer

    When the dimmer is at 50% power, the switches are switching their highest voltage (>325 V in Europe) and the sudden surge of power causes the coils on the inductor to move, creating a buzzing sound associated with some types of dimmer; this same effect can be heard in the filaments of the incandescent lamps as "singing". The suppression ...

  7. Lighting control system - Wikipedia

    en.wikipedia.org/wiki/Lighting_control_system

    The term lighting control system refers to an intelligent networked system of devices related to lighting control. These devices may include relays, occupancy sensors, photocells, light control switches or touchscreens, and signals from other building systems (such as fire alarm or HVAC). Adjustment of the system occurs both at device locations ...

  8. Li-Fi - Wikipedia

    en.wikipedia.org/wiki/Li-Fi

    Li-Fi is a light communication system that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of data in visible light. [2]

  9. RF switch matrix - Wikipedia

    en.wikipedia.org/wiki/RF_Switch_Matrix

    The Switch Matrix is made up of discrete electronic components including RF switches and signal conditioners that are mounted together in a mechanical infrastructure or housing. Cables interconnect the switches and signal conditioners. The switch matrix employs a driver circuit and power supply to power and drive the switches and signal ...
