Abstract: An automated sliding window mechanism is disclosed. An automated sliding window mechanism includes a motor attached to a first component of a sliding window and configured to open and close the sliding window, a controller that controls the motor, and at least two air pressure sensors in communication with a processor. If the window is open, based on signals from the air pressure sensors, the processor determines whether a draft is flowing through the window. If the window is closed, based on signals from the air pressure sensor, the processor determines whether a draft would flow through the window if opened. The processor sends a signal to the controller to either open or close the window, depending on whether a user has elected to have a draft flow through the window. In a preferred embodiment, a system is provided with at least two automated windows.

Abstract: In various example embodiments, a low energy electric motor brake is described comprising one or more electronic switches that connect the input wires to an electric motor together, thus shorting out the motor and braking the motor. The electronic switches are separate from the control system, and provide the braking function. This alleviates the motor controllers and other system control units from providing the braking function to the motor. The electronic switches require minimal to no power in order to maintain the brake to the motor. The control unit may be placed in a low power or sleep mode while the electronic switches maintain the brake.

Abstract: A headrail for a motorized window covering is described that includes a motor and a gearbox coupled to the motor that is configured to actuate a window covering. The headrail includes a safety detector with one or more sensors that detect an irregular strain when the window covering is being raised. The headrail may further comprise a recoil mechanism or a deactivation mechanism to reduce the likelihood of damage to the window coverings and/or individuals caught or tangled in the window covering.

Abstract: Window blinds with automated mechanisms that require a power source often include a battery housing that is placed at least partially outside of the headrail. This is done to make room for mechanical devices that are required to be housed within the headrail. We disclose a battery housing which may be mounted within a headrail of a window blind. Consequently, the battery housing is not visible when the headrail is mounted. This creates a more aesthetically pleasing window treatment. The disclosed battery housing may include a base mounted on two elongated battery compartments. An elongated channel may separate the two elongated battery compartments. The elongated channel is designed to allow a tilt rod within the headrail to pass through.

Abstract: We disclose a headrail for window coverings that may include an extensible end cap and a gearbox which automatically adjusts the headrail mounting. The extensible end cap may include a mounting bracket which may be connected to a piston. The piston may be connected to a floating bearing. The gearbox may include a motor-driven main gear which rotates a threaded rod. As the threaded rod rotates, an end of the threaded rod may move toward a floating bearing. The floating bearing may apply force the piston which may transmit the force to the mounting bracket. The extensible end cap may also include a sensor which detects the amount of pressure or force applied to the mounting bracket. When the sensor collects a measurement below a defined level, the motor may actuate the main gear to rotate the threaded rod and apply additional force to the mounting bracket.

Abstract: A printed circuit board (PCB) test apparatus and testing method are described. The PCB test apparatus includes a motor connected to a gearbox that includes a gear that is directly connected to an output shaft. The test apparatus includes two printed circuit board connections for testing an electric-component connector that includes two circuit boards. One connection port includes a plurality of contact pins for attaching one of the PCBs while the other connector port is part of a position encoder that includes a diametrically magnetized magnet that tests the other PCB's ability to detect changes in magnetic fields. The apparatus is configured such that both PCBs of the electric-component connector are tested in tandem.

Abstract: We disclose a window blind which includes a metamaterial film on the slats. The metamaterial film reflects solar irradiance and is infrared emissive. The metamaterial fabric may contain silicon dioxide microspheres embedded in a polymer and the polymer may be coated with a silver coating. The long edges of the slats of the blinds may be attached to a sheet of substantially transparent infrared reflective optical interference film. When the slats of the blinds are open, the infrared reflective optical interference film may reflect infrared radiation thus preventing it from passing into the adjacent room while still permitting light to enter the room. The metamaterial film may inhibit both solar and infrared radiation from heating the adjacent room. Consequently, the disclosed window blinds promote radiative cooling instead of impeding heat transmission into an adjacent room.

Abstract: Motorized window coverings are described herein. Various embodiments may include roll-up window shades, vertical blind slats, and/or horizontal blind slats. In one example, a motorized roll-up window shade is described. The shade includes a tube, a flexible panel, a fixed bracket, a rotatable bracket, bearings, a motor, and one or more batteries. The tube may have a longitudinal axis perpendicular to a transverse axis. The fixed bracket may include a first segment and a second segment connected to the tube and movably connected to the first segment. The rotatable bracket may include an articulating joint and may rotate the tube along the transverse axis. The bearings may enable rotation of the tube along the longitudinal axis. The motor and batteries may be disposed within the tube. The fixed bracket may include an opening through which the batteries may be accessed.

Abstract: We disclose a window blind that includes a capacitor within each slat. Each plate of the capacitor may be connected to one of two batteries. At least one switch may be placed between each capacitor plate and its adjoining battery. When one switch is open, another switch may be closed thereby sending current to only one plate at a time. The plate that receives the current is negatively charged and the remaining plate is positively charged. The switch that is open may be changed to reverse the charges of the plates. This charge reversal may be actuated through a series of pull cord gestures from a user. By creating an electrical charge on the plates, dust is pulled from the air according to the net charge of the dust particles. The window blind therefore functions as an air purifier as well as a traditional window blind.

Abstract: We disclose a window blind which purifies the surrounding air using electrostatic interactions. The window blind includes slats which may have a strip of positively charged material, a strip of negatively charged material, or both attached to the top of the slat. In some embodiments, the positively charged material and the negatively charged material are attached to alternating slats. In other embodiments, the positively charged material and the negatively charged material are attached to the top of the same slate with a strip of insulating material positioned between them. The window blind may include an air-moving device which moves air past the slats so that dust particles with either a net positive charge or net negative charge may be attracted to the oppositely charged material on the slat. The air-moving device may be a vacuum or a fan. The positively and negatively charged materials may be removeable for cleaning.

The extensible end cap may include a mounting bracket which may be connected to a piston. The piston may be connected to a floating bearing. The gearbox may include a motor-driven main gear which rotates a threaded rod. As the threaded rod rotates, an end of the threaded rod may move toward a floating bearing. The floating bearing may apply force the piston which may transmit the force to the mounting bracket. The extensible end cap may also include a sensor which detects the amount of pressure or force applied to the mounting bracket. When the sensor collects a measurement below a defined level, the motor may actuate the main gear to rotate the threaded rod and apply additional force to the mounting bracket.

Abstract: We disclose an intelligent headrail for a window covering which includes an extensible end cap which applies force to the adjacent window or door frame to hold the headrail in place. The end cap includes a pressure sensor or a force sensing resistor to detect whether sufficient force is present to safely hold the headrail in place. The headrail may include a controller which is connected to the pressure sensor or a force sensing resistor. The controller may include program code which identifies the safety status of the window covering based on the pressure or force reading. The controller may include a data transmission port which transmits pressure or force readings to an output device. The program code may also send a report to the output device to indicate whether the force or pressure is moderately low or so low that the window covering is in danger of falling.

Abstract: A segmented solar module is disclosed. One or more Photovoltaic (PV) submodules are connected together with embedded parallel wiring that facilitates the sharing of power from a plurality of PV submodules to power one or more electrical devices. Each one of the two or more first submodules cover a surface area more than twice the size of the surface area covered by a second submodule. This allows the second submodule to be isolated from the first submodules to accommodate shading of the second submodule. Control electronics within each individual PV submodule allows the isolation of PV modules that are shaded or otherwise not productive. No external connecting wiring, or devices are required to make the system functional. All wiring, connectors and electronics are integral and embedded within each individual PV module. The PV modules have adhesive on the back to allow them to be installed without additional mounting hardware.

Abstract: A system to reduce drafts in front of a window is described. The system includes a window covering and a motor and gearbox that adjust the window covering. The system also includes a first temperature sensor, a second temperature sensor, and a microcontroller networked to the motor and temperature sensors. The first temperature sensor is positioned above the window covering within a thermal convection zone of a window associated with the window covering, and the second temperature sensor is positioned below the window covering within the thermal convection zone. The microcontroller instructs the motor to adjust the window covering based on a temperature gradient from the first temperature sensor to the second temperature sensor.

Abstract: We disclose a window blind that includes a security feature. The disclosed window blind includes a plurality of slats, at least one of which includes a hollow core. The hollow core includes at least one pressure sensor, a controller, and a battery. The pressure sensor detects a change in pressure when an adjacent window or door is opened or broken. The controller may be connected to the pressure sensor and to multiple light fixtures and/or audio speakers throughout the building. Program code in the controller may receive instructions which include a defined order in which the controller sends a signal to each of the light fixtures and audio speakers causing them to actuate.
