    Abstract: An electric field sensor includes a light source; an electro-optical crystal, a first separator, a first wavelength plate, first and second light receivers, a differential amplifier, and a controller. The electro-optical crystal has light from the light source incident thereon and receives an electric field generated by an object. The first separator separates light emitted from the electro-optical crystal into a P wave and an S wave. The first wavelength plate changes a phase of light at a pre-stage of the first separator. The first and second light receivers receive the P wave and S-wave light respectively, and convert the received light into first and second electrical signals, respectively. The differential amplifier generates a differential signal between the first and second electrical signals. The controller adjusts a wavelength of the light source such that an output value of a direct-current component of the differential amplifier is within a value range.

  • Patent number: 12093009
    Abstract: Implementations are described herein for provisioning a device such as a DCN with configuration data for operation on a process automation network using an “out-of-band” communication channel. In various implementations, a temporary out-of-band communication channel may be established between a first and second DCNs. The out-of-band communication channel may be distinct from a process automation network through which the first DCN is to be communicatively coupled with other process automation nodes of a process automation system. Provisioning data may be transmitted from the second DCN to the first DCN over the temporary out-of-band communication channel. The provisioning data may include: information technology (IT) configuration data and operational technology (OT) configuration data. Subsequent to the transmitting, the temporary out-of-band communication channel may be closed.
