  • Patent number: 11362408
    Abstract: A wireless control device, such as a system controller for a load control system, may comprise a light-transmissive cover for an antenna that may be illuminated to provide feedback to a user of the load control system. The light-transmissive cover may receive light energy from a light-generating circuit to provide a visible display of the light energy. The wireless control device may be mounted to, for example, a ceiling, and the light-transmissive cover may extend from the wireless control device (e.g., down from the ceiling). The light-transmissive cover may be viewed by a user at large viewing angles and at a distance away from the wireless control device, which may simplify and improve reliability of commissioning of the load control system as well as speed up troubleshooting of the load control system after commissioning is completed.

  • Patent number: 11264718
    Abstract: An eight-frequency band antenna includes a carrier, a high-frequency segment, a low-frequency segment, a printed circuit board (PCB) and an inductor. The high-frequency segment is arranged on left side of the carrier and the low-frequency segment is arranged on right side of the carrier. The radiator on the bottom face of the carrier electrically connects with the micro strip of the PCB and the ground line of the ground metal when the carrier is fixed to the PCB. Moreover, the low-frequency segment is corresponding to a metal face with smaller area such that the low-frequency segment is at a free space to enhance the frequency response of the low-frequency segment and the bandwidth of the high-frequency segment. The area and the volume of blind hole on the carrier can adjust the effective dielectric constant to adjust the resonant frequency and bandwidth of the antenna.

  • Patent number: 11251530
    Abstract: Multiple frequency agile antenna structures are described. Each of the structures allows for tuning the antenna by changing its shape geometry (without changing the overall length of the antenna) and altering the frequency characteristics using variable capacitors. This is done by allowing control of the resonant frequency of the antenna with one main tunable capacitor and for independently varying the frequency and bandwidth of the antenna structure with the use of additional tunable capacitors embedded in the antenna structure.
