    摘要： A method for climbing and descending using an ascender including a differential reduction drive that includes an input shaft driven by a rotary power tool and an output shaft coupled to a pulley allowing a rope to be wound, reduces a forward rotational speed applied to the input shaft, and transmits the reduced forward rotational speed to the output shaft. The input shaft of the ascender is provided with a one-way clutch portion that allows a forward rotation and prevents a reverse rotation. The forward rotation of the pulley is performed by restricting rotation of the one-way clutch portion about the input shaft and driving the input shaft to rotate forward in a climbing direction by the rotary power tool. The reverse rotation of the pulley is performed by releasing the rotation restriction of the one-way clutch portion about the input shaft.

    摘要： Protective garments and face masks are provided that include a body portion having a plurality of exterior pleats configured to elongate in a first direction. The body portion further has an outer surface and an inner surface. The body portion further has an inner portion with a plurality of interior pleats connected between an upper edge of the body portion and a sealing surface. The inner portion is configured to elongate in a second direction at an acute angle from the first direction. In certain implementations, the sealing surface simultaneously contacts a nose and cheeks of a wearer in response to the elongation in the second direction.

    摘要： Integrated climb assist and fall arrest system and methods to assist users climbing ladders and vertical paths are disclosed. The integrated systems and comprise a controller connected to a user's harness, a static fall arrest cable, and a movable climb assist belt. The connection of the fall arrest components and the climb assist components may include physical connection, electronic connection, communication, or any combination thereof. The climb assist belt can be driven by a motor to provide an upwards climb assistance force to a user along a vertical path. The motor can be dynamically adjusted to continuously provide a level of climb assistance. The integrated controller is also configured to mechanically detect downwards movement and engage an overspeed braking mechanism when a threshold velocity or acceleration is detected.

    摘要： The disclosure describes a head wearable air purifier including a filter assembly, a motor-driven impeller for creating an airflow through the filter assembly to obtain a filtered airflow downstream of the filter assembly, and an ear assembly arranged to be worn over an ear of a user, the ear assembly comprising at least one light source for emitting light in a far UVC portion of the electromagnetic spectrum. The air purifier also includes a nozzle attached to the ear assembly, the nozzle comprising a nozzle inlet arranged to receive the filtered airflow downstream of the filter assembly, and a nozzle outlet for emitting the received filtered airflow from the head wearable air purifier. The at least one light source is arranged to illuminate at least part of the nozzle for the decontamination thereof.
