Abstract: An oilfield band cutter is useful for removing a band from a tubing string structure as the tubing string structure is being pulled up from the well. The oilfield band cutter includes a base frame with a central hole, an axis extending vertically and centrally through the frame coaxial with the central hole. A tubing follower member is coupled to the base frame and is positioned against an outer surface of the tubing string structure. A cutter is coupled to the tubing follower member, the cutter including an underside having a cutting edge. The cutting edge is positioned to engage against and cut bands on the tubing string structure.

Abstract: An exercise device consisting of a housing having a rope extending therethrough and wherein the rope is wound about a spool mounted on a driveshaft driven in a forward direction by a motor. The spool includes a one-way clutch for engaging the driveshaft in the forward direction and freely rotating on the driveshaft in the reverse direction. A recoil mechanism is coupled to the spool to rotate the spool in the reverse direction and rewind the rope.

The layers demonstrate improved adhesion between two materials without substantial modification of the adhesive matrix.

Abstract: Embodiments enables a wearable phototherapy apparatus that produces beneficial effects to a human body such as anti-viral effects, activation of stem cells, improvement in strength, improvement in stamina, pain relief via a non-transdermal container. May include an optional transdermal container that releases or increases copper peptide GHK-Cu in a subject's body. The non-transdermal apparatus reflects or emits specific wavelengths of light to elevate levels of the copper peptide GHK-Cu in the body. The non-transdermal apparatus includes one or more materials that prevent the Left-Handed molecule from direct contact with the body while the enclosure is coupled to the body and prevents the Left-Handed molecules from entering the body. Embodiments may include or be used with any bioavailable form of copper, e.g., such as copper glycinate as an anti-viral therapy and may include an anti-inflammatory or both.

Abstract: An exercise apparatus includes a rope wrapped around a spindle having a one-way clutch rotatably mounted on a driveshaft. The driveshaft is driven by a motor controlled by a motor controller. The controller is capable of driving and braking the motor such that the driving torque and the braking torque can be set at different values to ensure the safety of the apparatus and user.

Abstract: Group III nitride based light emitting diode (LED) structures include multiple quantum wells with barrier-well units that include III nitride interface layers. Each interface layer may have a thickness of no greater than about 30% of an adjacent well layer, and a comparatively low concentration of indium or aluminum. One or more interface layers may be present in a barrier-well unit. Multiple barrier-well units having different properties may be provided in a single active region.

Abstract: Various embodiments disclosed relate to a method of cold-spray deposition involving cooling the cold-spray nozzle by at least one of expanding and vaporizing a compressed cooling fluid in proximity to the cold-spray nozzle. The present disclosure also includes a cold-spray deposition spray head, a cooling jacket for a cold-spray deposition nozzle and a cold-spray deposition system comprising the same.

Abstract: A generally conical element is defined about a vertical axis and having a tip on the vertical axis, and a generally conical odd aspheric contour mirror surface that is defined upward from the tip relative to the vertical axis. A toroidal lens element, disposed to capture light data input of a surrounding scene reflected from the odd aspheric contour mirror surface, has a cross-section shape defined relative to a plane passing through the toroidal lens element and including the vertical axis and is defined by revolving a convex or concave lens surface cross-section shape around the vertical axis, the convex or concave lens surface cross-section shape defined from another axis parallel to the vertical axis but offset, wherein the toroidal lens element cross-sectional shape is constant in rotation about the vertical axis and imparts a toroid shape to the toroidal lens element relative to the vertical axis.

Abstract: Systems and methods for testing a protection relay, such as a primary bus protection relay, may include a testing device for providing current signals imitating current on both sides of a bus to the primary bus protection relay. The signals may be provided using signals corresponding with a signal format from merging units or other monitoring devices. The testing device may be configured to receive communications from the primary bus protection relay for evaluation of the operation of the primary bus protection relay.

Abstract: The present invention extends to methods, systems, and computer program products for changing vehicle configuration based on vehicle storage compartment contents. At an autonomous vehicle, a camera is mounted inside a storage compartment. The camera monitors the interior of the storage compartment. The camera can confirm that the storage compartment is empty when it is supposed to be empty and contains an object when it is supposed to contain an object. Any discrepancies can be reported to a human operator. The human operator can instruct the autonomous vehicle to change configuration to address discrepancies. In one aspect, a machine-learning camera memorizes a background pattern permeated to a surface of the storage compartment. The machine-learning camera detects objects in the storage compartment based on disturbances to the background pattern.
