Abstract: A two-handed dog leash with a rigid tubular member, a cleat assembly, a flexible dog leash, and a leash termination member. The tubular member has a hollow portion on one end and a slot portion on the opposite end. The cleat assembly is mounted on either side of a central aperture in the tube. The dog leash is inserted into the central tube aperture and is capable of extending perpendicular to the rigid handle member so that a person can hold the handle with two hands or can extend parallel to the rigid handle member and reside in the slot portion of the handle member so that a person can use the handle with one hand.

Abstract: An approach is provided for location correction using feature point correspondences between images or image sources. The approach, for example, involves processing a first image and a second image to identify a feature that is visible in both the first image and the second image. The first image has an image-to-ground correspondence between the feature in the first image and a geographic location. The approach also involves transferring the image-to-ground correspondence from the first image to the second image. The approach further involves using the transferred image-to-ground correspondence to reference the feature in the second image to the geographic location.

Abstract: A space saving and production cost saving inertia wheel training device is disclosed. In preferred embodiments the present invention comprises: a box where one or more inertia wheels are mounted horizontally; a pull belt which connects the inertia wheel with the user. The user stands with both feet on the box and can attach various accessories to the pull belt, like bars, harnesses, hip belt etc. to connect the pull belt to his body depending on the type of exercise the user wants to perform. The user adjusts the length of the belt to his body size. Then the user accelerates the inertia wheel. At the end of each movement of the user the flywheel needs to be decelerated or accelerated to allow the user to change the direction of his movement. The inertia of the wheel creates a braking force at deceleration and acceleration which leads to a training effect of the user's muscles.

Abstract: A vehicle hitch assistance system includes a powered suspension system supporting a rear of the vehicle at a height and a controller. The controller acquires position data for a coupler of a trailer, determines when the position data indicates that a hitch ball of the vehicle is aligned with the coupler, and causes the powered suspension system to raise the height of the rear portion of the vehicle until a threshold resistance value is detected.

Abstract: Given that power blackouts occur very infrequently, a TRANSportable GENset emissions reduction system (XGEN) that fixes a larger and more significant problem of reducing emissions from routine periodic testing of backup gensets, whereas the system may be scheduled to be shared by a multitude of gensets, thereby reducing costs through efficient use of capital expenditures while also increasing the quality of emissions reductions as compared to applying individual exhaust treatments each backup genset.

Abstract: A multi-speed drive hub for a bicycle contains: a hub shaft, a speed-changing transmission, a speed shifter, and a sprocket set. The hub shaft is connected on a center of a wheel rim of the bicycle and includes a speed-changing transmission. The speed-changing transmission includes at least one drive element and an actuator for driving multiple force segments of the speed-changing transmission to rotate reciprocately. The speed shifter includes a fitting sleeve which has a third fixing orifice corresponding to the at least one drive element. The sprocket set includes multiple speed cassettes of different diameters and includes multiple spacing spaces, each of which is defined any two adjacent speed cassettes. The fitting sleeve has multiple ribs and multiple flexible sheets. Each drive elements includes multiple retainers, multiple columns, and multiple force segments.

Abstract: The use of recycled materials can have significant economic value. With the increasing quantity of recycled material used in viscoelastic materials, especially asphalt mixture, understanding how they interact with original materials to produce a mixture that performs successfully, becomes critical. Currently, the technology to determine the effect of additives on the performance of asphalt mixture is lacking. The present invention relates to a new unified methodology for mechanical testing of asphalt mixture and other viscoelastic materials that improves the current practice in speed, convenience, and accuracy. A new improved specimen mounting method on Dynamic Shear Rheometer (DSR), a new recovery method for fine portion of asphalt mixture, and three new tests for the performance of recovered material using DSR is disclosed. The new methods provide performance grading of asphalt mixtures that is new to the industry and provide necessary tools for determining the effect of recycled materials on performance.

Abstract: This Padded Anti-Collision Bumper Collar provides blind dogs/animals a durable and comfortable apparatus that gives them more confidence to move around freely. The protective face hoop guard guides them around obstacles and helps to prevent face injuries. The structured collar is covered with fake fur padding to eliminate any irritation to the neck or throat. The protective face hoop guard is fully adjustable, and can be set at the correct height and shape around the animal's head. This anti-collision bumper collar utilizes a “bottom-weight balanced” design to keep the hoop level, and a plastic pinch-release buckle closure makes this Padded Anti-Collision Bumper Collar easy on/easy off! This invention offers a simple collar design, everything else currently on the market has harness or vest contraptions, which seem bulky and uncomfortable.

Abstract: A method for detecting vulnerable road users (VRUs) using wireless signals includes receiving, by a wireless receiver, wireless signals from mobile devices and determining received signal strength indication (RSSI) levels of the wireless signals. The wireless signals and the RSSI levels of the wireless signals received by the wireless receiver are analyzed so as to determine at least one location of the VRUs. A notification is issued to the vehicle or a driver of the vehicle based on the at least one determined location of the VRUs.

Abstract: A gas sensor 10 includes a tubular protective cover 30 having an element chamber 37 therein and configured to allow a measured gas to flow from the outside into the element chamber 37; and a long sensor element 20 including a detecting portion 23 located in the element chamber 37 and configured to detect a specified gas concentration in the measured gas. An inclination angle ?t of an axial direction of the sensor element 20 (i.e., a direction parallel to an element axis A1) in the element chamber 37 with respect to an axial direction of the protective cover 30 (i.e., a direction parallel to a cover axis A2) is 1° or greater.

Abstract: A tool for lifting open floor gratings and the like provides a solid anchor point on top surface of floor grating to facilitate handling and hoisting the grating. The tool includes a body member having an upwardly biased shaft with a push member with an opening on its upper end and a butterfly hook at its bottom end. During operation, a user pushes down on the push member until it is completely inside the body so that the butterfly hook reaches under the grating. The user then gives a quarter turn to the body member so that the butterfly hook turns and thus becomes wider than the cell of the grating so that it can hook up with two bearing bars as the user releases the push member and the shaft springs back up and the opening gets out of the body. Once this is done, a shackle is installed through the opening, and a steel cable placed therein, ready for lifting and hoisting.

Abstract: The invention is a data processing method and system for notifying petroleum geoscientists of contradictions in sentiment between petroleum geoscience topic associations in text. The data processing system makes the necessary calculations to detect petroleum geoscience associations of interest, predict their sentiment and report contradictions in sentiment. Contradictions can be calibrated with past business success and failures through time, such as exploration or operations, to create a classifier to predict future areas of opportunity and risk. In particular, the data processing system operates on any digital unstructured text derived from academic literature, company reports, web pages and other sources. This information is analyzed and utilized by the system assisting petroleum geoscientists to identify business opportunities and risks.
