Abstract: Systems and methods for calibrating an adaptive illumination system of an imager are presented. An example method includes causing the system to enter a calibration mode and providing a calibration illumination level from an illumination source to an environment. An imager captures one or more images of the environment. A processor determines, from the one or more images, a first illumination intensity to provide during an object detect mode operation of the system. The first illumination intensity has an illumination sufficient for detecting a presence of an object in the environment during the object detect mode. The processor stores the first illumination intensity in a memory, and configures the illumination source to provide illumination at the first illumination intensity while the adaptive illumination system is in the object detect mode, and (ii) provide illumination at a second illumination intensity while the adaptive illumination system is in a scanning mode.

Abstract: A hydrocarbon control system includes a base device, a field device, and a mobile device. The base device includes a key generator configured to generate a temporary key. The field device is configured to restrict or allow access based on verification of a received key. The mobile device is configured to communicate with the base device to receive the temporary key when in proximity of the base device, communicate with the field device to provide the temporary key to the field device when in proximity of the field device, and exchange data with the field device in response to the field device verifying the temporary key.

Abstract: A laminated tubular structure is obtained by a process in which a fabric sleeve is applied about a tube of thermoplastic polymer, following which plugs are inserted into the opposing ends of the liner. A liquid, such as water, is then introduced to the liner, and the liner is rotated about a horizontal axis while heat is applied to the exterior surface of the liner, causing the surface to become molten. The heat also causes vaporization of some of the liquid in the liner and the resulting vapor pressure causes the molten surface of the liner to expand radially into the interstices of the fabric sleeve. The inner surface of the liner remains solid and form-maintaining by reason of the liquid within the liner and heat absorbed on vaporization of liquid. Upon cooling there is obtained a good mechanical bond between the liner and sleeve.

Abstract: Surfaces of thermally conductive substrates are covered with thermoplastic polymers, particularly certain fluorocarbon polymers by bonding said polymeric materials directly to surfaces of said substrates. Adhesives, etchants, or the like are not used as bonding elements. The process involves treating the surfaces to make them wettable by water and then cleaning the surfaces, if necessary, followed by heating the substrate to a temperature at which the polymer melts, gels or softens (herein called the softening point), then placing the polymeric material into contact with the prepared surfaces and applying pressure on the polymeric material to force it into fusing and bonding contact with the heated surface and then cooling the substrate to a temperature below the softening point of the polymer. The products produced are preferably rolls. In their covered form as produced by this invention they are useful as processing rolls in office copier's fusing systems, rolls used in food cooking processes, and the like.

Abstract: A cathodic protection system monitor is coupled to an impressed current cathodic protection circuit used for corrosion protection of a submerged marine drive. The cathodic protection circuit includes one or more anodes and a reference electrode mounted below the water line and connected to an automatic controller for supplying an anode current which is regulated in order to maintain a predetermined reference potential on the protected structure. A switch selectively connects a light emitting diode (LED) lamp or other light source between the controller output and ground so that the controller current may, when tested, be used to operate the light source in order to confirm that power is available to the anode.
