  • Publication number: 20230287727
    Abstract: An example window operator assembly comprises a motor, communication circuitry, and processor circuitry. The communication circuitry being configured to provide a first type of wireless communications and a second type of wireless communication with a first wireless communication system and a second wireless communication system. And, the processor circuitry being configured to identify connection loss between the communication circuitry and the first wireless communication system, and in response, cause the communication circuitry to switch to the second wireless communication system and cause the window operator assembly to perform an action.

  • Patent number: 9668803
    Abstract: This disclosure describes impedance computation techniques that may reduce the effect of crosstalk, thus generating more accurate impedance measurements. In particular, an ablation system models the electrical interaction among the active electrodes and a common return electrode using a star-configuration resistor model. The ablation system computes one or more parameters of the star-configuration resistor model and adjusts the therapy based on at least the computed parameters of the star-configuration resistor model.
