  • Patent number: 10996236
    Abstract: An accelerometer wireless position transducer or sensor is physically coupled to a control device in a process control system and includes an accelerometer that generates a signal based on a position of the control device or its actuator. The transducer converts the accelerometer signal into a wireless signal that includes a value indicative of the actuator position, and causes the wireless position feedback signal to be transmitted over a wireless channel to a valve controller, e.g., by using a short-range wireless protocol. The controller controls the valve based on the value included in the wireless signal. In some configurations, the feedback signal is received at a device paired with the transducer, and the paired device transmits the feedback signal to the controller. The paired device may be paired with multiple transducers and/or sensors, and may transmit various feedback signals to multiple recipient controllers and other devices.

  • Patent number: 9459630
    Abstract: A system and method for controlling a remote valve includes temporarily driving or activating a battery-powered pilot valve assembly to place an operatively coupled output valve assembly in a switch position. A processor energizes a bistable valve of the pilot valve assembly to enable a fluid supply to drive the output valve assembly to a desired switch position, whereupon the pilot valve assembly may be de-energized and the switch position of the output valve assembly maintained.

  • Patent number: 9192082
    Abstract: An assembly configured to protect a circuit board from electromagnetic interference. The assembly includes a metal shield and an enclosure. The metal shield includes a metal plate and a plurality of tangs. The plurality of tangs are spaced about and extend transversely away from at least a portion of a perimeter portion of the metal plate. The enclosure has a bottom wall and at least one sidewall disposed around a perimeter of the bottom wall, the at least one sidewall configured to urge the tangs of the metal shield inward when the metal shield is disposed in the enclosure.
