  • Patent number: 11798447
    Abstract: Illumination testing is performed to passively check the health of a display of a shared device within a physical space, such as a conference room. A test pattern is output to the display within the physical space. Using a camera within the physical space, a test image of the physical space is captured while the test pattern is output to the display. A determination is then made as to whether the display is in a fail state by comparing the test image against a reference image depicting an expected illumination of the physical space according to the test pattern. Where the device is determined to be in a fail state, a notification indicating the fail state is transmitted to an administrator device to alert an administrator associated therewith of the fail state.

  • Patent number: 11774475
    Abstract: A reflectometer may include two directional couplers in a parallel configuration, sharing the same section of a signal line or through-line. For example, two directional couplers may be disposed across from each other on opposite sides of the shared through-line. One of the directional couplers may couple, to a first port of the reflectometer, a portion of the signal power of a first signal flowing from the first end of the shared through-line to the second end of the shared through-line, and the other directional coupler may couple, to a second port of the reflectometer, a portion of the signal power of a second signal flowing from the second end of the shared through-line to the first end of the shared through-line. The reflectometer benefits from reduced size and signal loss with respect to reflectometers having a serial configuration. When used in vector network analyzer (VNA) systems, this results in higher output power and higher dynamic range of the VNA.
