A measurement device has a sensor and includes a cylindrical housing, an optical fiber that is disposed along the long-side direction of the housing and that has one end disposed in the housing and the other end disposed outside the housing, a first substrate including a light receiving unit disposed on an extension of the one end in the housing, and a second substrate that is electrically connected to the first substrate via a flexible part having flexibility and is disposed at an acute angle or a right angle with respect to the first substrate.

A corrosion monitoring system includes one or more objects coupled to respective portions of a transformer tank. The one or more objects are configured to corrode before the respective portions of the transformer tank. At least one optical sensor is coupled to each of the objects. The at least one optical sensor has an optical output that changes in response to strain of the object. An analyzer is coupled to the at least one optical sensor. The analyzer is configured to perform one or more of detecting and predicting corrosion of the transformer tank based on the output of the at least one optical sensor.

An apparatus is disclosed for capturing image information. The apparatus includes a waveguide having opposed planar input and output faces. A diffractive optical element (DOE) is formed across the waveguide. The DOE is configured to couple a portion of the light passing through the waveguide into the waveguide. The light coupled into the waveguide is directed via total internal reflection to an exit location on the waveguide. The apparatus further includes a light sensor having an input positioned adjacent the exit location of the waveguide to capture light exiting therefrom and generate output signals corresponding thereto. A processor determines the angle and position of the coupled light with respect to the input face of the waveguide based on the output signals.

Optical fiber having a graphene coating, a method to apply a graphene coating onto an optical fiber, and a fiber optic cable having a graphene coating are disclosed. A first carbon based coating is applied to an optical fiber along a longitudinal axis of the optical fiber. A laser beam is focused at the first carbon based coating. A first surface of the first carbon based coating is photothermally converted into a first layer of graphene.

A multi-sensor component for the installation of at least two sensors at an individual port of a container for culturing biological material is provided. The multi-sensor component has a housing that can be introduced by a front housing segment into an uptake opening extending through the port of the container so that the front housing segment is facing the inside of the container. The multi-sensor component has a first sensor unit or a mount for a first sensor unit arranged on the front housing segment and has a second sensor unit or a mount for a second sensor unit arranged on the front housing segment.

Embodiments disclosed herein include a substrate support having a sensor assembly, and processing chamber having the same. In one embodiment, a substrate support has a puck. The puck has a workpiece support surface and a gas hole exiting the workpiece support surface. A sensor assembly is disposed in the gas hole and configured to detect a metric indicative of a deflection of a workpiece disposed on the workpiece support surface, wherein the sensor assembly is configured to allow gas to flow past the sensor assembly when positioned in the gas hole.

A telemetry system is provided for a coiled tubing-based work string and includes electrical transmission of power and data between sensors in a bottom hole assembly and a controller. One or more optic fibers are used to provide distributed temperature or acoustic sensing along the length of the work string.

The disclosed embodiments include an optical fiber having a graphene coating, a method to apply a graphene coating onto an optical fiber, and a fiber optic cable having a graphene coating. In one embodiment, the optical fiber includes an optical core that extends along a longitudinal axis. The optical fiber also includes a carbon based coating that covers the optical core along the longitudinal axis. The optical fiber also includes a layer of graphene formed on a first surface of the carbon based coating. The layer of graphene is formed from a laser induction process that includes focusing a laser beam at the carbon based coating to photothermally convert the first surface of the carbon based coating into graphene.

A punch head comprises a low profile hydraulic anvil piston with a punch across from a die on opposite sides of a gap between two legs. One of the legs comprises a position sensor disposed on the bottom of the leg. For example, a plurality of punch heads are disposed on a jig or frame and are positioned using one or more of the position sensors. For example, the position sensor is a mini fiber optic position sensor mounted in a recessed portion at the bottom of one or more of the punch heads.
