Patent number: 11979193Abstract: A method of modulating an optical camera communication (OCC) signal by an OCC transmission node in an OCC system includes acquiring a binary data signal, grouping the binary data signal for every k bits to convert the binary data signal into a global phase shift signal having an integer value from 0 to M?1 (=2k?1), generating a data signal group by mapping the global phase shift signal to first to Mth mapping sequences in the form of an n*M/2-bit sequence based on a preset symbol group mapping table, generating a pulse wave signal by modulating the data signal group, and blinking each of a plurality of light sources included in the OCC transmission node according to the pulse wave signal. Accordingly, performance of the communication system may be improved.Type: GrantFiled: November 28, 2019Date of Patent: May 7, 2024Assignee: KOOKMIN UNIVERSITY INDUSTRY ACADEMY COOPERATION FOUNDATIONInventors: Yeong Min Jang, Van Thang Nguyen, Minh Duc Thieu, Ngoc Nguyen Huy, Tung Lam Pham

Publication number: 20230101299Abstract: A motor-operated drive system for a window covering system including a headrail, a mechanism associated with the headrail to spread and retract the window covering, and a continuous cord loop extending below the headrail for actuating the mechanism to spread and retract the window covering. The drive system includes a motor, a driven wheel that engages and advances the continuous cord loop, and a coupling mechanism for coupling the driven wheel to a rotating output shaft of the motor for rotation of the driven wheel. The drive system includes a channel system for redirecting the continuous cord loop engaged by the driven wheel, or other mechanism for configuring the drive system so that continuous cord loop extends in a substantially vertical orientation. The coupling mechanism includes an engaged configuration in which rotation of the output shaft of the motor causes rotation of the driven wheel, and a disengaged configuration.Type: ApplicationFiled: December 5, 2022Publication date: March 30, 2023Applicant: Ryse Inc.Inventors: Trung Duc Pham, Alan Wing Hor Cheng, Marc Rashad Bishara

Patent number: 11583126Abstract: A motor driven system for raising and lowering a window covering executes motor ramp trajectory speed control. The motor ramp trajectory limits acceleration of an external motor from the idle (stationary) state to full operating speed, and limits deceleration of the motor from full operating speed back to the idle state. This function reduces stresses on a continuous cord loop drive mechanism. A control system manages solar heating effects in response to sunlight entrance conditions such as system sensor outputs, external weather forecasts, and other data sources. The system automatically opens or close the window covering to increase or decrease admitted sunlight under appropriate conditions. The input interface of the control system includes a visual display and input axis, which are aligned vertically if the window covering mechanism raises and lowers the window covering, and are aligned horizontally if the window covering mechanism laterally opens and closes the window covering.Type: GrantFiled: March 14, 2022Date of Patent: February 21, 2023Assignee: RYSE INC.Inventors: Trung Duc Pham, Alan Wing Hor Cheng, Marc Rashad Bishara, Clifton Pereira

Patent number: 11178992Abstract: A motor drive system for operating a mechanism for raising and lowering window coverings includes a motor operating under electrical power and an electrically powered drive system. The motor drive system advances a continuous cord loop in response to positional commands from a controller. An input-output device includes a capacitive touch strip that receives user inputs along an input axis, and an LEDs strip aligned with the input axis. A group mode module communicates the positional commands to other motor drive systems within an identified group to operate respective other mechanisms of the other motor drive systems. A set control module enables user calibration of a top position and a bottom position of travel of the window covering. The input-output device extends vertically on the exterior of a housing for the motor drive system, and the housing supports input buttons of the group mode module and the set control module.Type: GrantFiled: October 16, 2018Date of Patent: November 23, 2021Assignee: RYSE INC.Inventors: Trung Duc Pham, Alan Wing Hor Cheng, Marc Rashad Bishara, Clifton Pereira

Patent number: 11035171Abstract: A mounting system for a roller blind includes a tension bar for mounting under pressure between first and second sides of a windows frame. The tension bar may provide both long and short adjustment of mounting system width. The tension bar extends through a hollow roller tube of the roller blind, and through a clutch mechanism of the roller blind, and is coupled to end mounting fixtures. The length of the tension bar may be adjusted as a long adjustment of mounting width. Various mechanisms may be associated with one or both of the end mounting fixtures for short adjustment of mounting width, such as a latch mechanism, wedge mechanism, spring-loaded mechanism, or turn-buckle system. End pads at the ends of the blind provide friction and absorb excess pressure. The mounting mechanism serves as a universal window blind bracket and support rod, which requires no screws or nails to install.Type: GrantFiled: March 23, 2018Date of Patent: June 15, 2021Assignee: Ryse Inc.Inventors: Trung Duc Pham, Wilfrid Ngo
