  • Patent number: 11839007
    Abstract: An enhanced smart lighting system (ESLS) for use in buildings without neutral wire connections for wall switches. The ESLS entails both a no-neutral wire smart lighting switch (NNWSLS) and a physically separate load adapter. The NNWSLS includes a sensing, control, or communication system (SSCCS) such as integrated WiFi. The load adapter mitigates electrical fluctuations which may be induced in a power load (for example a lightbulb) by the smart lighting switch, particularly when the smart lighting switch is nominally powered off but still has some current flow. The load adapter is an intermediary between the power load and a conventional load receptacle. The load adapter has an integrated dummy load configured in parallel with the power load. The dummy load provides an electrical pathway for low levels of electricity which run through the light socket even when the NNWSLS is set to an “off” configuration.

  • Patent number: 11817867
    Abstract: An IQ mixer is used in a Pound-stabilized microwave source to detect amplitude modulation of the signal reflected from the reference resonator. By properly configuring the IQ mixer so that the LO and RF inputs are maintained in quadrature at the Q mixer, hence in-phase at the I mixer, lower levels of amplitude modulation may be detected at lower modulation frequencies compatible with optimal choices of resonator coupling and maximal phase to amplitude conversion.
