Abstract: The present invention relates to a patio screen shaver for cutting pine needles that are impaled in a patio screen. The patio screen shaver includes a blade, a handle adapter, a handle, and a blade mount. The blade is secured in the blade mount and positioned to slide along the surface of the patio screen during use. The handle adapter interconnects with the blade mount adapter and has a geared ring. A handle interconnects with the handle adapter, and a button with a geared end engages the geared ring securing the handle and the handle adapter together in a movable manner. A user can press the button, allowing the handle adapter to rotate, changing the angle of the blade with respect to the handle. Releasing the button interlocks the geared end and the geared ring setting the angle of the blade for use by the user.

Abstract: The present disclosure describes various aspects of crank-based lighting, which may improve visibility of pedal-based vehicles or conveyances.

Abstract: A stator vane includes an airfoil having an airfoil shape. The airfoil shape has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in one of TABLE I and TABLE II. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances expressed in a unit of distance by multiplying the Cartesian coordinate values of X, Y and Z by a scaling factor of the airfoil in the unit of distance. The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each Z value. The airfoil profile sections at Z values being joined smoothly with one another to form a complete airfoil shape.

Abstract: A user inquiry funnel system and method that enables an individual to submit an inquiry that is analyzed and sent to a specific group of individuals involved in a relevant and specific industry to determine whether they can provide an answer. A specific user inquiry funneling mechanism is deployed that parses the inquiry into multiple individual words and maps them against tags and variants thereof to determine whether there is a matching between any ones of the tags and variants thereof with any ones of the individual words. Based on the mapping results, a listing of matching tags and variants is produced that facilitates the identifying of responding users that are associated with any ones of the matching tags and variants thereof and that have provided one or more pre-defined replies. This allows for establishing of a communication between the inquiring user and one or more responding users.

In one example, a method for the folder-based content management system includes converting an existing infrastructure into editable assets and organizing the editable assets into a structure of a folder file system by recombining the editable assets into a new format. The folder file system may be rendered with the new format as a graphical user interface (GUI).

Abstract: A fuel cell vehicle includes a fuel cell assembly with at least a first fuel cell stack and a second fuel cell stack. Waste gas extracted from the first fuel cell stack is routed to an input of the second fuel cell stack. The first and second fuel cell stacks may be of the same size or the second fuel cell stack may be sized smaller than the first fuel cell stack.

Abstract: An alternating stack of insulating layers and sacrificial material layers is formed over a substrate, and support pillar structures are formed through the alternating stack. Stepped surfaces are formed by patterning the alternating stack and the support pillar structures. A retro-stepped dielectric material portion is formed over the stepped surfaces. Memory openings and memory opening fill structures are formed through the alternating stack. Electrically conductive layers are formed by replacing at least the sacrificial material layers with at least one electrically conductive material. Contact via structures are formed through the retro-stepped dielectric material portion on the electrically conductive layers. A first support pillar structure is located directly below a first contact via structure.

Abstract: Systems and methods for processing image data representing a document to remove deformations contained in the document are disclosed. A system may include one or more memory devices storing instructions and one or more processors configured to execute the instructions. The instructions may instruct the system to provide, to a machine learning system, a training dataset representing a plurality of documents containing a plurality of training deformations. The instructions may also instruct the system to use the machine learning system to process image data representing a target document containing a target document deformation. The machine learning system may generate restored image data representing the target document with the target document deformation removed. The instructions may further instruct the system to provide the restored image data to at least one of a graphical user interface, an image storage device, or a computer vision system.

Abstract: Aspects of the disclosure include methods, apparatuses, and non-transitory computer-readable storage mediums for point cloud compression. An apparatus includes processing circuitry that encodes information associated with a current point of a plurality of points of a point cloud. The plurality of points is partitioned into multiple bounding boxes. The processing circuitry determines whether a first size of a hash table is greater than or equal to a predetermined maximum size of the hash table. The processing circuitry removes information associated with non-boundary points in the multiple bounding boxes from the hash table based on the first size of the hash table being greater than or equal to the predetermined maximum size of the hash table. The processing circuitry stores the encoded information associated with the current point into the hash table.
