Abstract:
The present invention is an apparatus, system, method, computer program, and computer program product for controlling window coverings to adjust admitted daylight. More particularly, the present disclosure relates to a control system for controlling the amount of daylight admitted through adjustable window coverings. In an embodiment of the present invention, the system includes a stand-alone open loop proportional control subsystem including a calculation or algorithm that is operable to convert a sunlight sensor signal to a blind slat position based on a predetermined curve stored in memory. In another embodiment of the present invention, the system is operable to transmit the sunlight sensor information, for example, such as in Lux, to an external system, which may then provide blind slat position requests based on some other curve, algorithm, or user need. The blind slat position may be controlled by the system to avert undesireable solar heat gains and also achieve significant daylight harvesting.
Abstract:
A low-power radio - frequency (RF) receiver is characterized by a decreased current consumption such that the RF receiver may be used in control devices, such as battery powered motorized window treatments and two -wire dimmer switches. The RF receiver uses an RF sub- sampling technique to check for the RF signals and then put the RF receiver to sleep for a sleep time that is longer than a packet length of a transmitted packet to thus conserve battery power and lengthen the lifetime of the batteries. The RF receiver compares detected RF energy to a detect threshold that may be increased to decrease the sensitivity of the RF receiver and increase the lifetime of the batteries. After detecting that an RF signal is being transmitted, the RF receiver is put to sleep for a snooze time period that is longer than the sleep time and just slightly shorter than the time between two consecutive transmitted packets to further conserve battery power.
Abstract:
A motorized window treatment (110) provides a low-cost solution for controlling the amount of daylight entering a space through a window (104). The window treatment (110) includes a covering material (112), a drive shaft, at least one lift cord rotatably received around the drive shaft and connected to the covering material (112), and a motor (150) coupled to the drive shaft for raising and lowering the covering material (112). The window treatment (110) also includes a spring assist unit (135) for assisting the motor (150) by providing a torque that equals the torque provided by the weight on the cords that lift the covering material (112) at a position midway between fully-open and fully-closed positions, which helps to minimize motor usage and conserve battery life if a battery (138) is used to power the motorized window treatment (110). The window treatment (110) may comprise a photosensor (164) for measuring the amount of daylight outside the window (104) and temperature sensors (160,162) for measuring the temperatures inside and outside of the window (104). The position of the covering material (112) may be automatically controlled in response to the photosensor (164) and the temperature sensors (160,162) to save energy, or may also be controlled in response to an infrared or radio-frequency remote control (118).
Abstract:
The invention describes a heat insulating window with incorporated micro-blinds, where the position of the micro-blinds can be controlled from outside. The heat insulating window described in the invention enables the position of the inside micro-blinds to be adjusted from the outside, by turning a rosette (17) that turns a cylindrical magnet (15) with transversal polarisation, which through the magnetic field engages another cylindrical magnet (10) with transversal polarisation, located inside the window on a shaft (3) on which two drums (4) are fitted, holding the higher ends of two ladders (6) supporting the micro-blind blades; the shaft (3), the two drums (4) and the magnet (10) are located under the higher bar of the heat insulating window, inside an aluminium shape (1) in the form of an upside down "U" with loose edges, slightly bent towards the inside to hold two stands (2) where the drums (4) sit on microbearings (7).
Abstract:
A conveyor comprises laterally spaced apart lifting/holding slats (12) and laterally spaced apart conveying slats (10) between the lifting/holding slats (12). The conveying slats (10) are advanced in a first direction for conveying a load and are retracted in a second direction for returning them to a start position. The lifting/holding slats (12) have lower portions (62) which reciprocate and upper portions (60) which move up and down. Cams (92, 94) operate in response to longitudinal movement of the lower portions (62) to raise and lower the upper portions (60).
Abstract:
A window covering product has a headrail, a first rail substantially parallel to the headrail, and a first set of lift cords attached to the first rail passing through and out of the headrail, A second rail is substantially parallel to the headrail and to the first rail. A second set of lift cords is attached to the second rail and passes through and out of the headrail. A first tassel is attached the first set of lift cords. A second tassel has a channel through which the first set of lift cords pass and is attached to the second set of lift cords. In one embodiment, a top down bottom up blind, a window covering material is attached between the first rail and the second rail. The lengths of the lift cords are selected so that when the window covering material becomes tightly stacked between the two rails, continued pulling of the second tassel also pulls the first tassel raising both rails together. A second embodiment is a shade with an independent liner or a double shade. The first rail is attached to the window covering that faces the interior of the room. The second rail is attached to the liner or window covering material nearest the window. This arrangement causes the liner to rise whenever the front layer is raised to a point where the bottom of the front layer is adjacent the bottom of the liner.
