    摘要: A method comprises measuring a light intensity at a window; determining if the light intensity exceeds a cloudy-day threshold; operating in a sunlight penetration limiting mode to control the motorized window treatment to control the sunlight penetration distance in the space; enabling the sunlight penetration limiting mode if the light intensity is greater than the cloudy-day threshold; and disabling the sunlight penetration limiting mode if the total lighting intensity is less than the cloudy-day threshold. The cloudy-day threshold is maintained at a constant threshold if a calculated solar elevation angle is greater than a predetermined solar elevation angle, and the cloudy-day threshold varies with time if the calculated solar elevation angle is less than the predetermined solar elevation angle. The cloudy-day threshold is a function of the calculated solar elevation angle if the calculated solar elevation angle is less than the predetermined solar elevation angle.

    摘要: The file of this patent contains at least one drawing/photograph executed in color. Copies of this patent with color drawings)/photograph(s) will be provided by the Office upon request and payment of the necessary fee.
    The sole FIGURE is a front view of two portions of a display screen or portion thereof with set of graphical user interfaces showing the claimed design.
    The peripheral clashed broken lines illustrate the perimeters of two portions of the display screen and form no part of the claimed design.
    The bracket indicates a set; the bracket itself forms no part of the claimed design. The elements of the set are arranged relatively on the drawing sheet for the convenience of illustration, and the placement of each element relative to another, or to the drawing sheet, forms no part of the claimed design.
    The claim is directed to the collective appearance of the set of graphical user interfaces.

    摘要: An occupant detection device may be configured to detect an occupant in a space where the occupant detection device is installed. The occupant detection device may include an occupant detection circuit that is configured to determine locations of one or more occupants in the space. The occupant detection device may also include a low-power detection circuit that is configured to indicate an occupancy or vacancy condition in the space. The occupant detection device may include a control circuit that is configured to determine that the low-power detection circuit indicates that there are no occupants within the space. The control circuit may determine that there is movement in an occupant map or a region of interest (ROI) as indicated by the locations of the one or occupants as determined by the occupant detection circuit. The control circuit may configure masked regions around the locations of the movement, and store the masked regions in memory. The movement detected by the occupant detection device within the masked regions may be ignored when determining an occupant count for the space.
