摘要： Various implementations include methods of identifying data for producing a user-customized mask, systems for producing the same, a user customized mask, and an elongated support. To produce the mask or elongated support, 3D-data is received that defines the contour and dimensions of at least a portion of user's face. The 3D-data is determined by analyzing vector data associated with an area around the nose and mouth of the user, for example. A contact area(s) and a face contacting surface within the contact area are identified on the portion of the face of the user based on the 3D-data. And, structure-data based on the 3D-data and the identified contact area is provided for designing and producing a mask contacting surface. The mask contacting surface causes a portion of the mask to match the contour of the face contacting surface of the user.

摘要： A list of highly suitable textiles and a method to combine them into a durable reusable filtration medium with high particles filtration efficiency (PFE) and breathability that lasts over 50-75 laundering cycles. Filtration medium achieves PFE only through mechanical means, without fragile and harmful physicochemical pre-treatments. Different textiles are assembled considering their individual breathability and their complementary in terms of PFE on different particles' sizes to achieve good breathability and high PFE on a large range (20 nm-4 μm) after many laundering cycles, or several layers of the same textile are paired, while varying the fibers' orientation and dimensions in each layer to increase efficiency. This assembling method highly improves PFE, service life and performances' stability of the filtration medium by addressing structural weaknesses linked to anisotropy in each layer, and by protecting their fine fibers from mechanical wear and clogging through a face-to-face closed filtration cell-type pairing.

摘要： A rapid donning face mask is disclosed. The rapid donning face mask is desirable for emerging situations in which the user is unable to maintain proper social distancing. When needed the user deploys a filter element that is coupled to the fingers of a user's hand via rings. As the user splays their fingers, the filter element deploys, allowing the user to cover their mouth and nasal openings with the filter element.

摘要： A portable electric rescue tool, such as spreader and cutter tool, that allows for manual or remote operation, and operates on a DC power source, which may be an external power source and/or an onboard rechargeable battery. For example, the tool includes a battery cradle or battery attachment portion adapted to removably receive a rechargeable battery pack and electrically couple the battery pack to the tool. The tool also includes a power adapter that is adapted to be removably coupled to the battery attachment portion instead of the battery pack, and allows the tool to be electrically connected to an external DC power source, such as a vehicle battery or other DC power source.

摘要： Described herein is a disinfecting system for a respirator. The disinfecting system may comprise a ultraviolet irradiation component configured to emit ultraviolet (UV) irradiation in a direction of a filter cartridge of the respirator. The ultraviolet irradiation component may be integrated with the filter cartridge or may be contained in a separate cover adapted to connect to the filter cartridge. The disinfecting system may also comprise a ultraviolet irradiation component configured to emit ultraviolet (UV) irradiation in a direction of an exhale port of the respirator. The ultraviolet irradiation component may be integrated with the exhale port or may be contained in a separate shield adapted to connect to the exhale port.

摘要： The present disclosure provides a filtration media for filtering one or more airborne particles. The filtration media may comprise a membrane comprising one or more polymeric layers to filter the airborne particles. The filtration media may have high filtration efficiency and high breathability. Additionally, the present disclosure provides devices (e.g., face masks) comprising the filtration media which may be used to filter airborne particles (e.g., bacteria, viruses) and to protect the wearer (e.g., from infection).

摘要： A device for enhancing efficiency of an air mask (204) wearable by a user to cover the mouth and nose of the user includes an elongated chamber (202) fluidly couplable at a proximal end thereof to an air opening (205, 205′) of the mask (204). A filter element (206) formed of flexible material is wrapped around a sidewall of the chamber either internally or externally and has a surface area that is at least twice as large as that of the mask for filtering air flowing through the chamber in either direction, and a one-way valve (227, 228) is mounted in association with the opening for allowing filtered air inhaled by the user to pass from the chamber to the mask or for allowing an air exhaled by the user to pass from the mask to the chamber.

摘要： A respiratory mask system is presented. This respiratory mask system includes an inflatable harness and a bone conduction device to provide audio to a user while wearing the respiratory mask system. The bone conduction device is installed on or interconnected with a portion of the inflatable harness, such as a tube of the inflatable harness that is positioned at least somewhat in proximate to a user's ear. Inflation of the inflatable harness may press the bone conduction device against the user to enhance the delivery of audio to the user.

摘要： A fall arrest device includes a braking device, a frame, and a rotating member connected to the frame. The rotating member includes a main body and a plurality of pawls which are pivotally connected to a mounting portion of the main body. Each of the pawls has an abutting portion, a pivot, and a body portion. The braking device has a plurality of abutted portions. When a rotation speed of the rotating member is greater than or equal to a predetermined rotation speed, the abutting portions abut against the abutted portions to stop a rotation of the rotating member. When the rotation speed of the rotating member is smaller than the predetermined rotation speed, the body portion of each of the pawls touches a periphery of the abutted portions and swings as an outer diameter of the abutted portions of the braking device changes.

摘要： An impact tool includes a core and a plurality of projections. The core is formed of a first material that has a first specific gravity and each projection is formed of a second material that has a second specific gravity. The plurality of projections is configured on the core such that at least two projections intersect a first hypothetical plane disposed on the first side of the core and at least two projections intersect a second hypothetical plane disposed on the second side of the core and that is opposably facing the first side. Each of the first and second hypothetical planes is disposed a distance from the central lengthwise axis of the core that is greater than the radius of the core and less than the sum of the radius of the core and the length of a projection.
