Patent attributes
Various embodiments of a flexible, roll-up wall are described herein. The wall includes a roller drum having a selectively engageable one-way bearing, one or more power supplies, a motor, a flexible, sound-attenuating sheet, an electromagnet and at least one of a corresponding permanent magnet or ferromagnet, one or more conductive threads, a force meter, and a potentiometer. The motor is coupled to the drum by a transmission. The flexible sheet includes a base fabric and a polymer coating surrounding the base fabric, and is coupled to the roller drum at a first end of the sheet. The one or more conductive threads are woven into the base fabric. At least one conductive thread electrically couples the electromagnet to one of the power supplies. The potentiometer varies the current delivered to the electromagnet based on a force measured by the force meter.
