Abstract: Motorized window treatments may each adjust a position of a covering material to allow light into a space in a building. The control information for controlling the motorized window treatments may be stored and/or accessed to understand how the motorized window treatments are operating. The control information may indicate a control state and/or a position of the covering material when an identified daylight intensity is being received at the space. The control information may inform a user of the operation of the motorized window treatments and allow the user to adjust various control parameters by which the motorized window treatments may be controlled. Recommended adjustments may also be provided to the user based on a user-identified problem with the operation of the motorized window treatments. The recommended adjustments to the control parameters may be accepted by the user and may be stored for being accessed and/or edited.

Abstract: A drive system for raising and lowering a window covering includes a motor, a driven wheel configured to engage a continuous cord loop, a controller for the motor, a sensor, and a housing. The continuous cord loop includes an endless loop of flexible material and one or more sensor targets disposed on the endless loop of flexible material. The housing supports a guide rail adjacent the driven wheel. The sensor is mounted to the guide rail and is configured to generate a signal indicating presence of each sensor target when the target is located in proximity to or in contact with the sensor. The controller is calibrated to store an initial position of each sensor target along the continuous cord loop, and is configured to receive the signal indicating presence of the sensor target and to identify a drift from the initial position during continuing operation of the drive system.

Abstract: A system includes a window treatment adjacent to a window of a room. At least one motor drive unit is associated with the window treatment, for varying the position of the window treatment. A sensor measures a light level (e.g., an outdoor light level) at the window. A controller provides signals to the motor drive unit to automatically adjust the position of the window treatment so as to control a penetration distance of sunlight into the room when the window treatment is partially opened. The controller is configured to position the window treatment in a bright override position if the measured light level is at least a bright threshold value. The controller is configured to select the bright threshold value from among at least two predetermined values. The selection depends on an angle of incidence between light rays from the sun and a surface normal of the window.

Abstract: An example apparatus includes a sensor to detect a lateral edge of a door curtain within a guide of a door, and a controller to identify when the door curtain transitions from an operational state to a breakaway state based on a signal from the sensor, the operational state corresponding to when the lateral edge of the door curtain is enclosed by the guide as the door curtain moves between open and closed positions, and the breakaway state corresponding to when a portion of the lateral edge of the door curtain below an upper end of the guide breaks away from the guide.

Abstract: A smart window controller includes circuitry configured to establish a representative model of one or more building zones based on occupancy, construction, lighting, or cooling properties of a building. A lighting control strategy is implemented for the one or more building zones based on the representative model or one or more user preferences input at a first user interface screen of an external device. Automatic operations of one or more smart windows, cooling systems, or artificial lighting systems are controlled based on trigger points associated with the lighting control strategy, and a performance level of the lighting control strategy for the one or more building zones is determined based on one or more predetermined financial metrics.

Abstract: Methods of controlling tint of a tintable window to account for occupant comfort in a room of a building. Some methods include receiving weather feed data from one or more weather services (or other data sources) over a communication network, determining a weather condition based on the weather feed data, and determining a tint level for the tintable window based on the weather condition and based on whether a current time is within a time delay period at sunrise or sunset.

Abstract: We disclose a roller shade which may move the roller fabric to position either a light reflecting section or a heat absorbing section of the roller fabric toward a window. The two sections may be on opposite sides of a sheet of roller fabric which is connected to the roller tube at one end. The roller shade may wind the roller fabric around the roller tube then reverse the side of the roller fabric which faces the window. Alternatively, the roller fabric may be a continuous loop of fabric that includes a light reflecting section and connected to a heat absorbing section. The roller shade may move the continuous loop of fabric to position either section toward the window. The roller shade may include sensors, a motor, and a controller. The controller may be programmed to reverse the roller fabric in response to a sensor measurement.

Abstract: A gearbox that is configured to transmit torque from a motor shaft to a load shaft includes a limit mechanism The limit mechanism includes a strain wave gear including a circular spline, a flex spline and a wave generator. The circular spline is fixed to a housing of the gearbox coaxially with the load shaft, the flex spline is formed on a flexible rim of a rotatable cup that is coaxial with the load shaft, and the wave generator is coupled to the load shaft so as to rotate at the same angular velocity. The limit mechanism further includes at least one limiter structure coupled to the rotatable cup and at least one fixed switch, and is configured to stop rotation of the load shaft when the limiter structure engages the fixed switch.

Abstract: A motorized window treatment system controls a plurality of motorized window treatments to maximize daylight autonomy, while minimizing cognitive dissonance. The system may include motorized window treatments, window sensors, and a system controller. Each motorized window treatment may be operable to adjust a respective covering material to control the amount of light entering a space. Each sensor may be mounted adjacent to at least one of the motorized window treatments, and may be configured to measure an amount of daylight shining on the sensor. The system controller may receive sensor readings from the sensors and may control the motorized window treatments in response to the sensors to keep the covering materials aligned when the sensor readings are within a predetermined amount. The system controller may dynamically group and re-group the sensors into subgroups based upon the sensor readings and may control the motorized window treatments based upon the subgroups.
