Automatic compensation method based on temperature characteristics of rgb leds

An automatic compensation method based on temperature characteristics of RGB LEDs by first obtaining current temperatures of the RGB LEDs, and then adjusting a corresponding PWM duty cycle of each LED according to the current temperature of each LED to change drive currents of the RGB LEDs, thereby achieving compensation for the RGB LEDs. By determining a temperature adjustment coefficient of each LED based on the current temperature, temperature adjustment ratios, and an adjustment step size of the LED, and finally adjusting the PWM value according to the temperature adjustment coefficient to drive the LED, color shift is reduced. When performing PWM duty cycle adjustment, adjustment formulae are used, which only require obtaining the current temperature, the temperature adjustment ratios, and the adjustment step size of each LED, and then calculating according to the formula, therefore not requiring extensive data storage or data lookup and thus resulting in lesser computation.

A Method for Preparing Sr-Fe Layered Double Hydroxides Coating and its Application

of the invention The invention provides a method for preparing Sr—Fe layered double hydroxide coating and its application. Sr—fe layered double hydroxide coating with the characteristics of slow release of bioactive elements and acid neutralization can be prepared by reacting pre- 5 treated titanium base with Sr and Fe metal elements which have the function of regulating bone metabolism. At the same time, pure titanium or titanium alloy implant can promote osteogenic differentiation, inhibit osteoclastic differentiation and immune regulation. Sr—Fe layered double hydroxide coating can neutralize the acidic microenvironment of osteoporosis through the biological effect of inorganic materials, and release Sr2+ and Fe3+ 10 with good biosafety, which can promote the differentiation of osteoblasts, inhibit the differentiation of osteoclasts and enhance the function of immune regulation while self- degrading, thus exerting the regulatory function of microenvironment. Through local precise regulation, the shortcomings of systemic adverse reactions caused by existing osteoporosis drugs can be overcome.

Figure ground organization of 3-D scenes

Systems and methods for processing a pair of 2-D images are described. In one example, a stereoscopic set of images is converted into a collection of regions that represent individual 3-D objects in the pair of images. In one embodiment, the system recovers the 3-D point P for each point p that appears in both images. It estimates the 3-D orientation of the floor plane, and the image capture planes and their height from the floor. The system then identifies the collection B of points P that do not represent points on the floor and generates a projection C of B onto a plane parallel to the floor. It blurs the projection C and identifies peaks in the blurred image, then fits symmetric figures to the points in C around the identified peaks. The system projects the 3-D figures associated with the symmetric figures back onto the 2-D images.

Current clamp circuit based on BCD technology

A current clamp circuit based on BCD technology includes a current-outputting circuit, an output-current-sensing circuit, and a current clamp circuit. The current-outputting circuit outputs a current to the output-current-sensing circuit. The output-current-sensing circuit senses the output current. When the current actually output by the current-outputting circuit is greater than a clamp current, the current clamp circuit outputs a current clamp feedback control signal to the current-outputting circuit, so as to clamp the output current clamp at a set value.
