摘要:
Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.

Automated shade systems comprise motorized window coverings, sensors, and controllers that use algorithms to control operation of the automated shade control system. These algorithms may include information such as: 3-D models of a building and surrounding structures, shadow information, reflectance information, lighting and radiation information, ASHRAE clear sky algorithms, log information related to manual overrides, occupant preference information, motion information, real-time sky conditions, solar radiation on a building, a total foot-candle load on a structure, brightness overrides, actual and/or calculated BTU load, time-of-year information, and microclimate analysis. Modeled brightness information may be utilized to control shades.

A battery-powered motorized window treatment for covering at least a portion of a window may be adjusted into a service position to allow for access to at least one battery that is powering the motorized window treatment. A headrail of the motorized window treatment may be adjusted to the service position to allow for easy replacement of the batteries without unmounting the headrail and without requiring tools. The motorized window treatment may comprise brackets having buttons that may be actuated to release the headrail from a locked position, such that the head rail may be rotated into the service position. The headrail easily rotates through a controlled movement into the service position, such that a user only needs one free hand available to move the motorized window treatment into the service position and change the batteries.

The present invention relates to a control system for automatic calibration of a blinds system installed in a room, comprising: a controller (1, 8, 9) having a memory, a clock and a processor, an occupancy sensor (2, 7), an interior light sensor (3, 7), an exterior light sensor (4). The control system is characterized in that the control system is arranged to run an automated calibration of the blinds system when the exterior light sensor indicates an outside light level above a predetermined threshold, the occupancy sensor indicates that no person is present in the room, and a predetermined time has passed since the last calibration. The invention further relates to a method for automatic calibration of a blinds system installed in a room using a control system comprising a controller (1, 8, 9) having a memory, a clock and a processor, an occupancy sensor (2, 7), an interior light sensor (3, 7), an exterior light sensor (4), the method comprising the step of: running an automated calibration of the blinds system when the exterior light sensor (4) indicates an outside light level above a predetermined threshold, the occupancy sensor (2, 7) indicates that no person is present in the room, and a predetermined time has passed since the last calibration.

A method for hybrid solar tracking, and an apparatus for hybrid solar tracking and a photovoltaic blind system using the same are disclosed. The method includes generating first predicted power output data by analyzing first measured power output data of the past; generating a lagged error; constructing a regression analysis (RA) model, and deriving second predicted power output data; constructing an artificial neural network (ANN) model, and deriving third predicted power output data; selecting either a method for solar tracking based on photovoltaic power output or a method for solar tracking based on location and time depending on whether the second measured power output data of the present time falls within a filtering range based on a first error range and a second error range; and determining the directions of photovoltaic panels according to the selected method for solar tracking.
摘要:
The automatic window blind system provides gear driven window blind control. A solar power with back up battery provides energy to operate the window blinds and a light emitting diode strip that changes light colors depending upon daylight and night conditions. A plurality of toothed rack drives is driven by and drives rack gears in ensuring a positive operation of window blind hooks in pivoting window blinds that snap into the window blind hooks. A printed wiring board assembly controls functions and is accompanied by a rack sensor that cooperates with an optical sensor. The optical sensor and the rack sensor automatically position window blinds based upon light intensity.

摘要:
Selective processing of one or more packets to be transmitted from a wireless communication device to another wireless communication device is effective to reduce the peak to average power ratio (PAPR) of the transmission. The one or more packets are transmitted via two or more sub-bands of an available transmission medium. The number of coefficients or factors within that sequence corresponds to the number of sub-bands via which the one or more packets are to be transmitted. Also, a phase ramp or time-domain cyclic shift may be added to one or more of the packets after having undergone multiplication by one of the coefficients or factors within the sequence.
摘要:
A mobile device that is configured for wireless communication may be configured to operate as a remote control device in a lighting control system, controlling one or more lighting control devices of the lighting control system. The remote control device may control the light intensity in a space, for instance at a location of the remote control device, in response to an ambient light intensity measured at the remote control device. The remote control device may define a user interface for receiving an input that indicates a desired light intensity at the location. The remote control device may measure the ambient light intensity at the location via a light detector, compare the measured ambient light intensity to the desired light intensity, and cause the one or more lighting control devices to adjust the ambient light intensity at the remote control device until it agrees with the desired light intensity.
