  • Patent number: 11979193
    Abstract: 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.

  • Publication number: 20240030687
    Abstract: A protection device against pulsed currents intended to transmit signals having frequencies lying in a transmission frequency band. The protection device has a signal conduction path and a shielding disposed around the signal conduction path. The signal conduction path has two spark gaps mounted in series and an inductor element linking a portion of the signal conduction path situated between the spark gaps. The inductor element is linked to the shielding. The protection device is configured as a high-pass filter allowing passage over the signal conduction path of the signals having frequencies lying within the transmission frequency band.

  • Publication number: 20230101299
    Abstract: 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.

  • Patent number: 11583126
    Abstract: 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.

  • Publication number: 20220275336
    Abstract: The invention relates to a method for generating a cardiac tissue mimetic, comprising the steps of mixing cardiomyocytes (CM) and fibroblasts (FB) at a ratio from 2.5:1 to 10:1, thereby providing a first mixture, incubating said first mixture, such that said cardiomyocytes and said fibroblasts form a spherical structure, adding endothelial cells (EC) to said spherical structure at a ratio of cardiomyocytes (CM) to endothelial cells (EC) from 1.5:1 to 4:1, thereby providing a second mixture, and incubating said second mixture, such that a cardiac tissue mimetic is formed. The invention further relates to a cardiac tissue mimetic comprising cardiomyocytes (CM), endothelial cells (EC), and fibroblasts (FB), wherein said cardiac tissue mimetic comprises sarcomeric structures and vascular structures. Further aspects of the invention are the cardiac tissue mimetic for use in a method for heart tissue repair or replacement and a method for screening a compound using a cardiac tissue mimetic.

  • Patent number: 11178992
    Abstract: 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.

  • Patent number: 11035171
    Abstract: 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.

  • Patent number: 10950352
    Abstract: A computer-readable storage medium storing program instructions to perform a method of classification of short time series in order to detect a neurodegenerative disorder. The method includes receiving a plurality of sensor data collected from subjects with and without the neurodegenerative disorder over a period of a few seconds as the short time series, generating phase-space vectors from the plurality of sensor data in which each vector is a state of a dynamical system in space and time, transforming the phase-space vectors into a grayscale image representing recurrences of a state-space vector in the same area of the phase space, extracting temporal texture features of the grayscale image to obtain a multi-dimensional time series; inputting the multidimensional time series, without the grayscale image, to the Long Short Term Memory (LSTM) network, and classifying, by the LSTM network, the plurality of the sensor data as the neurodegenerative disorder or not.
