Abstract: A system including an additive management system configured to oversee hydrate formation in a hydrocarbon extraction system, the additive management system including a flow meter configured to measure a fluid flow rate, a first sensor configured to measure at least one of a fluid property and an environmental condition, and a chemical injection device configured to inject a hydrate inhibitor into a fluid flow.

Abstract: In a system and a method for extrinsic calibration of an image capture apparatus of a vehicle, the vehicle includes a vehicle body and a movable part configured to rotate around a known rotation axis relative to the vehicle body. The system includes an image capture apparatus having an image capture device mounted on the vehicle body and configured to capture at least two images of the movable part, an identification unit configured to identify at least two image features in the images, a calculation unit configured to calculate a calculated direction of the rotation axis relative to the image capture device based on the image features, and a calibration unit configured to determine extrinsic parameters of the image capture apparatus based on the calculated direction of the rotation axis relative to the image capture device and the known parameters of the rotation axis relative to the vehicle.

Abstract: In a system and a method for extrinsic calibration of an image capture system of a vehicle, the vehicle includes a body and a body portion, wherein the body portion is configured to rotate around a rotation axis relative to the vehicle. The system includes an image capture system with an image capture device mounted on the body portion and adapted to capture at least two images of the body and/or surrounding area of the vehicle, an identification unit adapted to identify at least two image features in the images, a calculation unit adapted to calculate a direction of the rotation axis relative to the image capture device based on the image features, and a calibration unit configured to determine extrinsic parameters of the image capture system based on the calculated direction of the rotation axis relative to the vehicle. The image capture system is calibrated using degrees of freedom of movement that the image capture device has due to being mounted on a movable portion of the vehicle.

Abstract: A solar mirror comprising a transparent substrate (51) (e.g. clear float glass or low-iron glass), a reflective layer (53) (e.g. of silver) provided on a surface of the substrate, and a coating layer (54, 55) (e.g. a paint layer or other protective layer) provided over the reflective layer, wherein the reflective layer is provided in a thickness of at least 1600 ?.

Abstract: A multi-function modular storage light unit including a primary housing unit and detachable modules such as a radio and an auxiliary flashlight. The primary housing unit contains a spotlight, a power switch, and a handle to carry the unit. There is also a storage compartment built into the primary housing unit. The modules preferably include belt clips for hands-free transport. The modules are removably attached to the primary unit by way of an attachment mechanism which may include alignment features and a latching mechanism. The modules may alternatively be removably attached by their belt clips to sleeves arranged on the primary housing. Each of the detachable modules and the spotlight is independently powered.

Abstract: An attachable flashlight includes a housing for containing a power source and a light source. The housing has an elongate opening, a generally round opening and a hook disposed on one of its sides for allowing a user to releasably secure the flashlight to a support.

Abstract: The flashlight apparatus of the present invention includes a rechargeable flashlight and a bracket which mounts the flashlight to a support during recharging. The flashlight includes two light sources, a first switch for activating its power source and a second switch for selecting which of the two light sources the power source energizes.
