A window treatment retention system may include a roller shade assembly and one or more retention brackets that at least partially enclose the roller shade assembly and do not interfere with operation of the roller shade assembly. The retention brackets may be configured to absorb an impact force associated with detachment of the roller shade assembly from a mounted position. The retention brackets may deflect upon absorbing the impact force, and may limit displacement of the detached roller shade assembly from the mounted position. The retention brackets may deflect such that the roller shade assembly does not pass through openings defined by the retention brackets. The retention brackets may deflect such that the width of at least one of the openings defined by the retention brackets does not expand beyond a distance that is equivalent to the diameter of a roller tube of the roller shade assembly.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly mounted in at least one of: the top portion and the bottom portion. The frame includes a top portion, a bottom portion, and two jambs forming first slots extending lengthwise along at least a portion of the jamb. The first slots each include a screen edge retention feature. The screen assembly includes a roller assembly substantially hidden from view, a screen material attached to the roller assembly, and a plurality of raised features. Edges of the screen material extend into the first slots. The raised features are attached to each of the edges of the screen material. The raised features are configured to engage the screen edge retention features and retain each of the edges of the screen material at least partially within the first slot of each of the two jambs.

An improved roller shade system provides increased support, additional adjustments and/or increased safety. The slip plate allows the brake to slip forward and minimize damage to the clutch spring when a user pulls too hard on the hembar. The center drive mechanism extends through a bracket to allow the drive shaft to distribute power in both directions and drive two shade tube simultaneously. The tube adapter absorbs force from the spinning shade tube to minimize damage to the other components and the bead chain. The sprocket has a back wall supporting the sprocket, allowing the sprocket 130 to rest on the back flange of the sun gear to minimize pressure on the gears. An adjustment arm is adjusted to help level the shade band. The shade bands may be removed without disturbing the other shade bands in the system. A height of a hembar may be adjusted by rotating a rod within the hembar.

A pet door system is provided including a casing configured to attach the pet door system to a building and a flexible door attached to the casing. In some embodiments, the door is segmented and comprises a plurality of interlocking segments that are rotatable with respect to each other. In some embodiments, the pet door system further includes a rotating cylinder attached to the flexible door and rotatably connected to the casing and a motor comprising a gear head, where the gear head is attached to the rotating cylinder, such that when the motor is activated, the gear head is rotatable in a first direction to wind the flexible door around the rotating cylinder. In some embodiments, the pet door system may be operated by a pet-worn collar and/or may be remotely controlled via a mobile device.

The quick release device may comprise a shade tube, a gear wheel engaging with the shade tube, a pawl removably engaging with the gear wheel and a solenoid configured to activate the pawl. The activation of the pawl disengages the pawl from the pawl wheel and allows the shade tube to rotate. The quick release device may also include a shade tube, a rotating brake plate engaging with the shade tube, a spring configured to apply pressure to the rotating brake plate and a magnet configured to apply magnetism to the spring. In response to the magnet applying magnetism to the spring, the spring contracts and releases pressure on the rotating brake plate and allows the shade tube to rotate.

A system for a closure lock comprises a battery-powered remote module with a lock mechanism for operating the lock, the remote module communicating with a base station coupled to a closure controller, the base station able to send lock control signals to the remote module to operate the lock. The module is arranged to have an operation mode and a non-operation mode, power consumption in the non-operation mode being lower than that in the operation mode, and is further configured to switch between the modes based on instructions from the base station. In the non-operation mode, the module maintains a communication link with the base station based on a pre-established synchronisation protocol.

The invention provides reliability against interference between base station and remote module, whilst greatly limiting the power consumption of the remote module.
