  • Publication number: 20240144430
    Abstract: A computing system performs artificial-intelligence (AI) super-resolution (SR). The computing system includes multiple processors, which further includes a graphics processing unit (GPU) and an AI processing unit (APU). The computing system also includes a memory to store AI models. When detecting an indication that the loading of the GPU exceeds a threshold, the processors reduce the resolution of a video output from the GPU in response to the indication. One of the AI models is selected based on graphics scenes in the video and the respective power consumption estimates of the AI models. The processors then perform AI SR operations on the video using the selected AI model to restore the resolution of the video for display.

  • Patent number: 8072162
    Abstract: An LED lamp includes a bi-direction constant current device coupled between a power supply and a LED load to provide stable positive and negative currents to the LED load. The bi-direction constant current device includes a pair of current sources face-to-face or back-to-back connected in series between the power supply and the LED load, and two protective elements shunt to the pair of current sources, respectively.

  • Publication number: 20110175516
    Abstract: A bulb shell includes a transparent shell base having an opening, a largest outer diameter and a light projection surface defined by a critical boundary on the shell base, and a coating on the shell base in a region between the opening and the critical boundary to increase brightness of the light projection surface. The critical boundary lies between a first position where the largest outer diameter is located and a second position distant from the first position by 33% of the dimension of the largest outer diameter in a direction away from the opening. The coating will significantly increase the brightness of the light projection surface when the bulb shell is used in a LED light bulb.
