Patent number: 8757238Abstract: Various apparatuses, methods and systems for directionally controlling a movable partition are provided. In one embodiment, an apparatus may include at least one roller assembly coupled to a portion of a movable partition. A roller element of the roller assembly may be configured to maintain contact with an adjacent surface (e.g., a floor) while the partition is displaced along a desired path even though the adjacent surface may exhibit unevenness, undulations or other substantially nonplanar surface features. In one embodiment, the apparatus may be configured to maintain a substantially constant force between the roller element and the adjacent surface. In another embodiment, the apparatus may be configured to maintain a force between the roller element and the adjacent surface substantially within a specified range. A steering actuator may also be used to select, or change, the orientation of the roller assembly with respect to the partition.Type: GrantFiled: May 20, 2013Date of Patent: June 24, 2014Assignee: Won-Door CorporationInventors: E.

Patent number: 8493033Abstract: Apparatuses, systems, and methods for providing battery-backed power to movable partitions are disclosed. A power converter generates a DC output from an AC input. The DC output may be selectively decoupled from an enabled DC output such that the DC output can be monitored for acceptable operation in-situ. The enabled DC output may be selectively coupled to a battery output terminal. A charge current may be sensed between the enabled DC output and the battery output to control charging of the battery with a pulse-width modulation operation by controlling the selective coupling of the enabled DC output to the battery output. The enabled DC output and the battery output are coupled in a logical-OR configuration to generate a supply output providing current from the enabled DC output and the battery. The supply output may drive a movable partition controller and a motor configured for opening and closing a movable partition.Type: GrantFiled: August 24, 2010Date of Patent: July 23, 2013Assignee: Won-Door CorporationInventors: Kevin D.
