Publication number: 20240121685Abstract: A method of reducing gray energy consumption and achieving optimal gray energy saving for carbon neutralization is proposed. In a cellular network, each cell or BS (group of cells) has renewable (green) and non-renewable (gray, on-grid power) energy sources. The renewable (green) energy is highly variable and unpredictable, while non-renewable (gray, on-grid power) is stable but is not renewable and thus has more carbon impact. Each cell or BS (group of cells) services is associated UEs when it is on. In one novel aspect, a cell or BS (group of cells) that consumes more non-renewable energy can give some or all of its served UEs to another cell or BS (group of cells) that consumes less non-renewable energy.Type: ApplicationFiled: September 21, 2023Publication date: April 11, 2024Inventors: Chien-Sheng Yang, I-Kang Fu, YUAN-CHIEH LIN, Chia-Lin Lai, Yu-Hsin Lin, Yun-Hsuan Chang

Patent number: 8330513Abstract: A voltage hold circuit includes four switches, an operational amplifier and a capacitor. By turning the switches on and off, the operational amplifier functions as a unity-gain buffer. In the normal operation mode, the positive input end of the operational amplifier is coupled to a node, and the output end of the operational amplifier is coupled to the capacitor. Thus the voltage of the capacitor is equal to the voltage of the node. In the power off mode, the positive input end of the operational amplifier is coupled d to the capacitor, and the output end of the operational amplifier is coupled to the node. Thus the voltage of the node is equal to the voltage of the capacitor. Therefore, the voltage hold circuit is able to hold the voltage of the node in the power down state.Type: GrantFiled: March 18, 2011Date of Patent: December 11, 2012Assignee: Etron Technology, Inc.Inventors: Yu-Sheng Lai, Feng-Chia Chang
