However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosures as defined by the appended claims.

[0026] In an embodiment, the present disclosure relates to a system for controlling electrical appliances. The system may include a rotary element configured to rotate in one or more positions and a driving module associated with the electrical appliances. The system may include a controller operatively connected to the rotary element and the driving module.

Further, the controller may simultaneously generate and transmit a position synchronization signal to the rotary element to synchronize a position of the rotary element to the changed operational state of the electrical appliances.

[0027] Various embodiments with respect to the present disclosure will be explained in detail with reference to FIGs. 1 to 4.

[0028] FIG. 1 illustrates an exemplary block diagram of a system (100) for controlling electrical appliances (108), in accordance with an aspect of the present disclosure.

[0029] Referring to FIG. 1, the system (100) for controlling electrical appliances (108) may include a rotary element (102), a driving module (104) and a controller (106). The electric appliances (108) may include, but not limited to home appliances or industrial appliances. The home appliances may include but not limited to fans, television, lights, airconditioner, and the like. The controller (106) may be communicably coupled to the rotary element (102) and driving module (106). The rotary element (102) may be configured to rotate in one or more positions relative to a reference position, each corresponding to a specific control value or operational state of the electrical appliance (108). The one or more positions may be discrete, such as fixed notches representing predetermined levels (e.g., fan speed steps or temperature settings), or continuous, where a change in position of the rotary element (102) directly translates to a proportional change in output (e.g., dimming a light). In an example, the system (100) may include a smart regulator device and the smart regulator device may include the rotary element (104). The rotary element (104) (also referred herein as regulator, regulator cap, or regulator rotor herein) may be configured to control operation of an electrical appliances (108). In an embodiment, the driving module (104) may include a Triode for Alternating Current (TRIAC) for regulating the flow of Alternating Current (AC) to the electronic appliances (108) and a driver circuit. The rotary knob (rotary element (104))may serves as a physical user interface, allowing the user to set the desired operating level of the electronic appliances (108). The actual modulation of electrical power delivered to the load may be performed electronically by the TRIAC, which acts as a solid-state AC power regulator. The driving module (104) may receive triggering commands from the controller (106) through the driving module (104), and / or an the driver circuit. The driving module (104) may ensure proper isolation and current amplification to safely and reliably enable the TRIAC at precise points in an AC cycle, enabling phase-control operation. This arrangement separates user interaction (via the knob) from electrical power regulation (via the TRIAC), providing smooth, efficient, and reliable control of devices such as lights, fans, or heating elements.

[0030] In an embodiment, the controller (106) may be implemented as one or more microprocessors, microcomputers, microcontrollers, edge or fog microcontrollers, digital signal processors, central processing units, logic circuitries, and / or any devices that process data, based on operational instructions. Among other capabilities, the processor may be configured to fetch and execute computer-readable instructions stored in a memory of the system (100). The memory may be configured to store one or more computer-readable instructions or routines in a non-transitory computer readable storage medium, which may be fetched and executed to collect a plurality of data from a plurality of sources. The memory may comprise any non-transitory storage device including, for example, volatile memory such as Random Access Memory (RAM), or non-volatile memory such as Erasable Programmable Read-Only Memory (EPROM), flash memory, and the like.

[0031] In an embodiment, the system (100) may include the rotary element (102) that may be manually rotated by the user to set appliance parameters Further, the system (100) may include a user interface (110), such as a touchscreen panel, mobile app, or remote control, that allows for digital input. The user interface (110) may be communicably coupled to the controller (106) through a communication module. The controller (106) may receive control inputs from either source (i.e., by manual operation or by user interface). The control input may be any user-generated action, signal, or command intended to change or adjust the operational state of the electrical appliances (108). When the rotary element (102) is operated manually, the controller (106) may detect the position of the rotary element (102) via the position sensors or by using position tracking. Based on the detected position of the rotary element (102), the controller (106) may generate a first control signal, and may transmit the first control signal to the driving module (104) that changes operational state of the electronic appliances (108). The first control signal may be a signal generated by the controller inresponse to a detected manual change in position of the rotary element (102). The first control signal may be indicative of a corresponding operational state adjustment to be applied to the electrical appliances (108), and may be transmitted to the driving module (104) to control operations of the electrical appliances (108). In an example embodiment, an operational state of the electrical appliances may include, but not limited to, adjusting fan speed, light intensity, or temperature and the like. When the user changes settings through the user interface (110), the controller (106) may generate a second control signal to the driving module changes operational state of the electronic appliances (108) and simultaneously issue a position synchronization signal to the rotary element (102), thereby ensuring that the physical position of the rotary element accurately reflects position change in the user interface (110). The second control signal may be a signal generated by the controller in response to the control input received from a user via a user interface, the second control signal may be indicative of the corresponding change in the operational state to be applied to one or more connected electrical appliances, and may be transmitted to the driving module (104) to control the operation of the electrical appliances (108). Further, the position synchronization signal may be (an electrical or logical signal) generated by the controller (106) for aligning the position of the rotary element (102) with the current operational state of the electrical appliances (108). The controller (102) may send the position synchronization signal to the rotary element (102) to reflect the position change in the user interface (110).

[0032] In an embodiment, controller (106) may be configured to transmit the position synchronization signal to the motor driver for driving the motor to synchronize the position of the rotary element (102) to the changed operational state of the one or more electrical appliances (108). This bidirectional feedback of the system (100) may guarantee that manual and digital inputs always remain in sync, providing a consistent, intuitive, and reliable user experience across home, commercial, or industrial environments.

[0033] In an embodiment, the controller (106), in response to the manual operation of the rotary element (102) by the user, the controller (106)may transmit the changed operational state of the electrical appliances (108) to the user interface (110). By transmitting the changed operational state of the electrical appliances (108) to the user interface (110), the system (100) may maintain real-time synchronization and consistency between physical and digital control points. By instantly updating the user interface (110) to reflect manual adjustments, the system (100) ensures that the user receives immediate visual confirmation of the change, thereby enhancing usability and reducing risk of confusion or mismatched states. This capability is particularly important in environments where multiple control modes such asphysical knobs, mobile applications, or wall-mounted touch panels coexist, as the system (100) keeps all interfaces aligned with true operational status of the electrical appliances (108).

[0034] In an embodiment, the system (100) may include the position sensor operatively coupled to the rotary element (102) and the controller (106). The position sensor may be configured to generate a position sensing signal corresponding to the change in the one or more position of the rotary element (102). The position sensors may include, but not limited to, magnetic sensor, hall sensor, potentiometer, optical sensor, proximity sensor, inductive position sensor, encoder, and capacitive position sensor. For detecting the position of the rotary element (102), the controller (106) may be configured to determine the change in one or more positions of the rotary element (102) based on the position sensing signal generated by the at least one position sensor.

[0035] In an embodiment, the system (100) may include environmental sensors The environmental sensors may be configured to determine environmental parameters associated with ambient environment. The environmental sensors may include, but not limited to, temperature sensors, humidity sensors, pressure sensors, light sensors, gas sensors, Air Quality Index (AQI) sensor, Volatile Organic Compounds (VOCs) sensors and Volatile Sulfur Compounds (VSCs) sensors. Upon receiving the environmental parameters from the environmental sensors, the controller (106) may be configured to determine a change in ambient conditions based on the environmental parameters, generate a third control signal if the change in the ambient conditions exceeds a predefined threshold value of the plurality of environmental parameters and transmit the generated third control signal to the driving module to change the at least one operational state of the one or more electrical appliances. The third control signal may be (electrical or logical signal) generated by the controller (106) in response to detected changes in ambient environmental conditions, as measured by environmental sensors associated with the system (100).

[0036] In an embodiment, when the environmental sensors such as temperature sensors, humidity sensors, pressure sensors, light sensors, gas sensors, air quality sensors (e.g., AQI, VOCs, VSCs) detect that any of environmental parameters exceed predefined threshold values, the controller (106) generates the third control signal. The third control signal may be transmitted to the driving module (104) to change at least one operational state of the electrical appliances (108) accordingly. For example, it may trigger adjustments in HVACsystems, fans, air purifiers, or lighting to optimize comfort, safety, or energy efficiency based on the ambient environment.

[0037] Further, the controller (106) may simultaneously generate and transmit the position synchronization signal to the rotary element to synchronize the position of the rotary element to the changed operational state of the one or more electrical appliances. The controller (106) may transmit the changed operational state of the one or more electrical appliances to the user interface (110).

[0038] In an embodiment, the system (100) may include a calibration sensor in an example, the calibration sensor may include an Infra-Red (IR) sensor. The calibration sensor may be configured to indicate a reference position of the rotary element among the one or more positions of the rotary element (102). The controller (106) may be configured to receive the indicated reference position of the rotary element (102) and calibrate one or more positions of the rotary element (102) based on indicated reference position of the rotary element. The reference position may be detected by the calibration sensor, such as an Infra-Red (IR) sensor, which indicates to the controller (106) that the rotary element (102) is aligned with this specific reference mark. Once identified, the controller (106) uses this reference position as a zero or starting point from which all other positions of the rotary element (102) are measured and mapped. Through identifying the reference position, the system (100) may correct any positional drift or misalignment, ensuring accurate mapping between physical orientation the rotary element (102) and the intended operational states of the electrical appliances (108). In an embodiment, the controller (106) may be configured to operate the motor via the motor driver, in at least two modes. The two modes may include a torque control mode to generate a tactile feedback corresponding to the change in one or more positions of the rotary element (102) during the manual operation of the rotary element and a speed control mode to synchronize a position of the rotary element (102) to the changed operational state of the one or more electrical appliances (108). The tactile feedback through the rotary element (102) may include, but not limited to continuous (smooth, constant resistance), stepped (distinct notches or clicks at set positions), smooth (minimal resistance for easy fine tuning), vibration based (short pulses to signal changes or limits), and force / torque feedback (varying resistance to emulate stops or boundaries).
