A hail protective cover for a vehicle is provided. The hail protective cover is able to be deployed over a vehicle immediately preceding or during a hailstorm and allow for reentry into the vehicle while covered. The hail protective cover includes a cover sheet having one or more layers adapted to enclose a body of a vehicle when a perimeter of the cover sheet is positioned over the vehicle to form an interior volume. The cover further includes a door panel cover that is aligned to be positioned over the door portion of the vehicle when covered. The door panel cover can be fastened and unfastened at an interface that extends along an interior edge and a periphery of the door panel cover. In an open configuration, the door panel cover is unfastened from the interior edge of the cover sheet, thereby permitting selective opening of the vehicle door.

A system for selectively opening flexible containers, such as plastic bags, in a mixed solid waste stream is disclosed, for use in Material Recovery Facilities (MRFs) or other contexts. The system may include a conveyor configured to transport waste, a sensor configured to detect the presence and position of flexible containers, and a multi-degree-of-freedom positioning device that moves a cutting tool relative to the containers. A processor, in communication with the sensor and positioning device, may calculate a cutting path and control the positioning device to execute the cutting operation. The system may utilize various cutting tools, including punches, blades, spades, shovels, and motorized saws, as well as non-contact fluid-based cutting technologies such as air or water jets. Additionally, the system can dynamically adjust the cutting trajectory based on real-time feedback and environmental conditions. The method provides an adaptable solution to open bags without damaging recyclable materials, improving throughput and reducing waste in mixed waste streams.

The invention belongs to the technical field of hydrogen energy storage and transportation, and relates to a multi-tank rapid butt joint and atmosphere cooperative control system suitable for a magnesium-based solid hydrogen storage material. The system is composed of a multi-path quick plug type interface bus, an index valve terminal, a double-layer main channel, a hollow cavity, a dynamic atmosphere regulation and control module and a butt joint guiding and anti-vibration assembly. A plurality of paths of quick plug type interface buses are in detachable airtight connection with hydrogen storage tanks, quick switching among multiple tanks is realized by utilizing selective opening of index valve islands, and oxygen and water contents in interfaces and channels are maintained within a ppm level range in a whole process by combining an inert barrier constructed by a double-layer main channel and a hollow cavity. The butt joint guiding and anti-vibration assembly effectively absorbs butt joint errors and reduces vibration transmission, and pulverization of the sheet-shaped magnesium-based solid hydrogen storage material is avoided. The system can be used in cooperation with a spiral conveying type solid material transfer device to form a complete solid storage and transportation system, and has the advantages of being reasonable in structure, safe, reliable and capable of achieving modular expansion.

This invention belongs to the field of special proportional control valve technology, specifically a digitally piloted high-temperature fluid proportional control valve and its control method. It includes a valve body, a valve core, an array valve group, and a control oil circuit. The valve body forms a pilot valve chamber and a main valve chamber. A piston is installed at one end of the valve core extending into the pilot valve chamber, dividing the pilot valve chamber into a rodless chamber and a rod chamber. A first cold oil inlet on the rodless chamber and the array valve group constitute a pilot control half-bridge for controlling the valve core position. The array valve group includes multiple high-speed switching valves connected to the first cold oil outlet. The position change of the valve core controls the flow rate of the main oil circuit, realizing the proportional regulation of the high-temperature fluid. The rod chamber is connected to a second cold oil inlet. The pilot oil circuit is a cold oil circuit, and the main oil circuit is used to control the high-temperature fluid. This application improves response speed and fault tolerance by setting multiple parallel high-speed switching valves, and enhances regulation accuracy through selective opening and closing of the high-speed switching valves.
