A motorized window treatment system may include a roller tube, a flexible material, a motor drive unit, and mounting brackets. The mounting brackets may include a stationary portion configured to be attached to a structure surrounding a window. The mounting brackets may include a movable portion configured to receive an end portion of a housing of a motor drive unit. The movable portion may be configured to operate the motorized window treatment between the operating position and the extended position in a circular-shaped path. A portion of the motor drive unit may be accessible when the motorized window treatment is in the extended position. The mounting brackets may include a stopping mechanism that is configured to prevent the motorized window treatment from extending beyond the extended position.

In various aspects, a covering for an architectural structure includes a bottom rail assembly that can be efficiently and effectively assembled during manufacturing of the covering. Specifically, in one embodiment, the bottom rail is configured such that one or more operating system components of the covering can be mounted within and directly supported by the bottom rail. In addition, a separate cover may be coupled to the bottom rail during the assembly process.

An integrated-optics MEMS-actuated beam-steering system is disclosed, wherein the beam-steering system includes a lens and a programmable vertical coupler array having a switching network and an array of vertical couplers, where the switching network can energize of the vertical couplers such that it efficiently emits the light into free-space. The lens collimates the light received from the energized vertical coupler and directs the output beam along a propagation direction determined by the position of the energized vertical coupler within the vertical-coupler array. In some embodiments, the vertical coupler is configured to correct an aberration of the lens. In some embodiments, more than one vertical coupler can be energized to enable steering of multiple output beams. In some embodiments, the switching network is non-blocking.

In one aspect, a covering for an architectural structure includes a headrail, a bottom rail supported relative to the headrail, and at least one stackable covering element positioned between the headrail and the bottom rail. The covering also includes an overpowered lift system configured to provide a lifting force that raises the bottom rail relative to the headrail towards a retracted position of the covering. In addition, the covering includes retention structure provided in operative association with the bottom rail, with the retention structure being configured to engage at least one hold-down bracket to hold the bottom rail in position relative to the headrail against the lifting force provided by the overpowered lift system.
