    Abstract: A process variable transmitter for measuring a process variable includes a process variable sensor configured to sense a process variable and provide a sensor output. Measurement circuitry receives the sensor output and provides a measured output related to the process variable. Output circuitry provides a device output on a two-wire process control loop based upon the measured output. The output circuitry has a transfer function that is a function of an adjustable analog circuit component. A motorized actuator is configured to adjust the adjustable analog circuit component to thereby change the transfer function of the output circuitry. An optional calibration controller is also provided.

  • Patent number: 10855205
    Abstract: The invention provides an energy generation and/or conversion system and method wherein an electrical power generator is controlled to periodically alternate between a contact-mode, during which elements of the generator are brought into contact to induce a state of charging, and a non-contact mode, during which plates of the generator are separated from one another and electrical energy is generated through electrostatic induction. Timing and duration of contact and non-contact modes are controlled by a controller, or by user commands, in dependence on a charge state of the elements of the generator: In this way elements are controlled to come into contact only when surface charge has fallen below a certain level, and re-charging is necessary; contact time between the elements may hence be minimised—thereby minimising incurred noise and surface wear—whilst still maintaining a given desired threshold power output.
