An automated window mechanism having a motor and a force measuring component. A movement path is defined for the window movement relative to a window frame. The force-measuring component measures the force required to move the window along the movement path. The force required is stored as a force map and is a function of position along the path. Deviations from the force map cause the motor to take measures which may include stopping the motor.

A latch assembly connected to the drive unit of a bi-fold door for retaining the bi-fold door secure to a building has elongated straps attached to rotatable latch drums mounted on the outer ends of the drive shaft of the drive unit. Lift drums powered by a motor driven gearbox raise and lower the bi-fold door. Latch assemblies having springs attached to the straps maintain tension on the straps during the opening and closing of the bi-fold door.

A system for reversibly providing a wall, comprising: a first panel comprising first track followers on each of opposite side edges of the first panel; a first pair of tracks adapted to receive the first track followers and that are generally vertical on opposite sides of a space, each comprising: a top at a point overhead, and a lower point part-way to the floor of the space; a second panel comprising: upper second track followers on sides of the second panel near a top edge of the second panel, and lower second track followers on sides of the second panel near a bottom edge of the second panel; wherein, as the first panel is lowered, the first track followers ride in one of the first pair of tracks until at least one first track follower reaches the bottom of the one of the first pair of tracks, thus allowing the first panel, when lowered, to form a first portion of the wall; a second panel comprising: upper second track followers on each of opposite side edges of the first panel proximate to a top edge of the second panel, lower second track followers on each of opposite side edges of the first panel proximate to a bottom edge of the second panel; a second pair of tracks that are generally vertical on opposite sides of the space to be divided and generally parallel to the first set of tracks, each comprising: a top at a point overhead, a junction where a spur track separates from the second track, a spur track at a point part-way to the floor that angles over from the second pair of tracks to a point below and in vertical alignment the first pair of tracks, a bottom at a point at or above the floor, wherein the lower second track follower interacts with the toggle switch, as the second panel is lowered, to move the toggle switch from a first position to a second position, and wherein the lower second track follower interact with the toggle switch, as the second panel is raised, to move the toggle switch from the second position to the first position; wherein the toggle switch, when in the second position, diverts the upper second track follower from the second pair of tracks into the spur; wherein the bottom of the second track is in vertical alignment with the first track; wherein, as the second panel is lowered, the lower second track followers reach the bottom of the second pair of tracks and the upper second track followers reach the bottom of the spur, thus allowing the second panel, when lowered, to form a second portion of the wall; and a toggle switch at the junction of the second track having a first position such that a track follower in the second track will continue past the junction remaining in the second track and will move the toggle to

The invention is an an anchor for attaching an automated window mechanism to a sliding panel of a window. The sliding panel has a border with an outer face generally perpendicular to the window. The anchor includes a base configured to be secured to the outer face. The base and mechanism mount has a first tongue-and-groove component protruding from the base away from the outer face. The anchor also includes a mechanism mount configured to be secured to the automated window mechanism, the mechanism mount having a second tongue-and-groove component protruding therefrom. The first tongue-and-groove component and the second tongue-and-groove components are shaped and aligned to permit the mechanism mount to slide relative to the base in a direction generally perpendicular to the window, and to thereafter hold the mechanism in proper alignment relative to the sliding panel of the window.

A system for reversibly dividing a space is disclosed. Independent panels, with track followers attached to both narrow sides, move along parallel tracks. The panels start in an overhead storage space. The tracks are shaped such that as the panels move from the storage space into the space to be divided, one panel stops higher and the next panel slides down and then under the first panel. These panels preferably form a single-plane divider in the space.
