Abstract: Methods, systems, and techniques for agricultural greenhouse gas estimation. Farm data in the form of at least one of revenue generated by a farm, crop information for one or more crops grown on the farm, and land use/farm practice data for land used on the farm to grow the one or more crops is obtained. An emissions estimate is determined based on the obtained data and caused to be displayed to the user via a graphical user interface. A user may be a person responsible for managing multiple farms. That user may be presented with aggregate emissions-related information for all farms, including projected future emissions under various scenarios, and may also iteratively experiment with different farm data values in order to attempt to reduce projected emissions or increase data quality/emissions estimate accuracy.

Abstract: A well drilling tubulars bin system comprises a well drilling tubulars bin and control device. The bin comprises a frame structure, and an elevator mechanism, for holding multiple layers of a plurality of well drilling tubulars. The elevator mechanism comprises a liftable support structure, and a left and right hydraulic cylinder. The support structure is liftable from a lower position to an upper position. The support structure is raised and lowered in a level manner, or with a tilt angle. The elevator mechanism comprises a first left lift arm and a first right lift arm. The first left and right lift arms are at a first end rotatably connected to the support structure, and at a second end opposite from the first end rotatably connected to the frame structure. The left and right hydraulic cylinders are connected to the respective lift arms for rotating the respective lift arm.

Abstract: The spatial resolution of a fiber optical Distributed Acoustic Sensing (DAS) assembly is enhanced by: arranging an optical DAS fiber with a series of contiguous channels that are sensitive to vibration in a U-shaped loop such that substantially parallel fiber sections include pairs of channels that are arranged at least partially side by side; transmitting a series of light pulses through the optical fiber and receiving back reflections of said light pulses by a light transmission and receiving assembly; and processing the received back reflections such that back reflections stemming from at least one pair of channels that are arranged at least partially side by side are correlated to each other.

Abstract: An improved electromagnetic coil tattoo machine offers the operator the opportunity to customize the machine's structural and operating properties. An embodiment of the invention provides a tattoo machine having at least one electromagnetic support coil which may include a coil core which has threaded holes which accommodate fasteners used to structurally secure and support 2 or 3 piece sub-frame members which house the secondary components that a conventional one-piece frame would house—such as the spring/armature bar, the binding posts and the preferred tube vice system. Accordingly in one embodiment, the support coil assemblies themselves act as a primary structural frame member. In a further embodiment, the electromagnetic support coil assembly may also use removable instead of non-removable retaining washers and O-rings to retain magnetic wire windings such as to allow the operator to customize and repair the magnetic wire.

Abstract: A circuit board construction which reduces unwanted electrical effects and lower signal quality resulting from the use of vias in relatively thick circuit boards or in circuit boards carrying signals of relatively high frequency. The circuit board includes a through-hole in the circuit board substrate for carrying a conductive via stub, the stub having an inherent stub characteristic; and a compensation element, such as a surface mount capacitor, positioned on the substrate such that when the stub is carried by the through-hole the inherent stub characteristic is adjusted to define a compensated stub characteristic.

Abstract: Prior art electromagnetic coil technology in tattoo machines employs a round steel post to alternately repel and attract an armature bar retained by a spring, reciprocally moving a needle bar and attached needle groupings into and out of the skin in the act of tattooing. The present invention uses a hexahedron shaped steel post to increase the surface area contacted on the armature bar, improving the magnetism and general movement of the bar. The improved rate of movement of the armature improves the overall functioning of the tattoo machine including the operator's ability to achieve more solid color, smoother shading, and more consistent lines. Removable retaining washers and o-rings are employed to allow the operator to customize and repair the magnetic wire.
