Patent number: 11396772Abstract: A motorized shade comprising a roller tube, a shade material connected to the roller tube, and a motor drive unit operably connected to the roller tube. The motor drive unit comprises a motor adapted to create torque to rotate the roller tube to lower or raise the shade material and a force sensor positioned at a point along the motor drive unit that resists the torque created by the motor resulting in a reaction force that is detected by the force sensor. The motor drive unit further comprises a motor control module adapted to receive sensor readings from the force sensor and control the motor in response to detecting an abrupt change in the reaction force using the received sensor readings to enable shade control via pulling of the shade material as well as or alternatively obstacle detection to minimize damage to the roller shade and users.Type: GrantFiled: December 10, 2019Date of Patent: July 26, 2022Assignee: Crestron Electronics, Inc.Inventors: Michael Campagna, Benjamin Slivka, Luis J.

Patent number: 10934774Abstract: A system and method for automatically determining at least one lower limit of a horizontal sheers style roller shade. The roller shade comprising a roller tube, a shade material attached to the roller tube and comprising a first vertical layer interconnected to a second vertical layer via a plurality of horizontal vanes, a motor adapted to rotate the roller tube, a current sensing circuit adapted to detect current levels of the motor, and a controller adapted to control the motor and comprising at least one memory. The controller determines at least one lower limit by driving the motor in a first direction, receiving current levels from the current sensing circuit, observing current level profile of the received current levels, detecting a point of change in the current level profile, and using the point of change to set at least one of a lower tilt closed limit and a lower tilt open limit.Type: GrantFiled: August 29, 2018Date of Patent: March 2, 2021Assignee: Crestron Electronics, Inc.Inventors: Michael Campagna, Benjamin Slivka, Luis J.

Patent number: 10612301Abstract: A motorized window treatment configure for automatically determining and reporting the tilt level of a motorized window treatment. The motorized window treatment comprises a window covering material, a motor configured for moving the window covering material from an opened position to a closed position, an accelerometer configured for measuring gravitational forces, and a controller configured for reporting the tilt level of the motorized window treatment. Particularly, the controller receives gravitational force measurements from the accelerometer, determines a tilt level of the motorized window treatment using the gravitational force measurements, compares the tilt level to a first threshold value, and issues an error signal when the tilt level exceeds the first threshold value.Type: GrantFiled: July 24, 2017Date of Patent: April 7, 2020Assignee: Crestron Electronics, Inc.Inventors: Charles R. Derk, Jr., Luis J. Rivera, Michael Campagna, Benjamin Slivka

Patent number: 10530279Abstract: An angle shift compensation system and method for controlling a sinusoidally driven motor to achieve efficient motion and reduced noise. The motor controller uses the angle shift compensation method to monitor the angle shift between a sinusoidal motor control signal configured to drive the motor and a feedback signal received from at least one position detector indicating the position of the motor rotor with respect to the motor stator. In response, the motor controller proportionally adjusts the amplitude of the motor control signal based on the monitored angle shift to maintain the angle shift substantially equal to an angle shift threshold.Type: GrantFiled: November 1, 2017Date of Patent: January 7, 2020Assignee: Crestron Electronics, Inc.Inventors: Luis J.
