Abstract: A motorized roller shade that detects obstacles in its travel that create excess torque by sensing the current draw from a motor and method by which the motor can calibrate itself to detect excess torque. During the roller shade's travel, it will record the instantaneous torque being generated at various points. For example, it will store the greatest value in the shade motor's non-volatile memory as the normal operating torque.

Abstract: An involute gear bracket system includes first and second involute gears. Each includes a circular base and a plurality of gear teeth extending outward from an outer region of a surface and evenly spaced apart from each other along a plurality of locations on the outer region of the surface. The shape of each gear tooth is defined by a varying cross-sectional involute profile, wherein starting from a first involute profile that is in a plane parallel to the surface of the circular base and extending outward from a center of the circular base, each location on the first involute profile is rotated about a corresponding axis while traversing a path defined by a corresponding imaginary ray extending from the center of the circular base to that location, the corresponding axis being tangential to an imaginary circle that encompasses the inner region of the surface and perpendicular to the corresponding imaginary ray.

The LED driver circuit comprises a dimmed input sense circuit, a microcontroller, and a power supply circuit. The power supply circuit generates a power supply from the dimmed AC input signal for powering the LED driver circuit. The dimmed input sense circuit detects an incoming duty cycle (Din) of the dimmed AC input signal. The microcontroller stores one or more dimming level parameters, receives the detected incoming duty cycle (Din) from the dimmed input sense circuit, and generates an output duty cycle (Dout) based on the detected incoming duty cycle (Din) and the one or more dimming level parameters. The LED driver circuit generates the output signal using the generated output duty cycle (Dout) for powering the LED element at a generated dimming level.
