  • Patent number: 11078704
    Abstract: A method of adjusting the closing force of a door coupled to a door closer assembly having a bias element. The method includes determining the kinetic energy of the door without using the weight or other dimensions of the door. The determined kinetic energy is used to adjust the closing force of an electro-mechanical door closer that includes a spring and a motor. The door includes the use of one, some of, or all of an accelerometer, an angular position sensor, a time to close, a breaking torque, and a controller to identify values a acceleration, velocity, and/or position of the door. The identified values are provided to the controller, which is configured to calculate the kinetic energy of the door. The calculated kinetic energy is used to determine the closing velocity of the door closure to ensure proper operation of the door at the point of installation.

  • Patent number: 10991238
    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.

  • Patent number: 10920487
    Abstract: A self-powered dynamic photovoltaic sunshade system having sunshades constructed of lightweight ETFE panels covered with at least one thin film of photovoltaic cells. The sunshades track the sun by light detectors, and move against the sun from east to west to block direct rays. The ETFE fabric is stretched on a lightweight frame, which rotates vertically around its axis as a pivotal panel for maximum solar protection. Sunshades rotate to face the sun by day, and reset to a starting position at night. Each sunshade is rotated by a stepped electric motor, powered by thin film(s) of solar photovoltaic cells. Sunshades are suspended between an electric motor shaft and a lower hinge. The sunshades are designed to provide sustainable dynamic shading for building facades exposed to different sun angles, are self-powered, and can generate electric power for other building functions, such as lighting and fan ventilation inside a building.
