  • Publication number: 20240247610
    Abstract: The present invention discloses an organic Rankine cycle (ORC) power generation system with a regenerator utilizing Liquefied Natural Gas (LNG) cold energy and industrial waste heat, the system comprising: an LNG regasification circuit, an ORC circuit, and an industrial waste heat circuit. The ORC circuit utilizes the cold energy released by the LNG regasification circuit and the heat energy dispersed by the industrial waste heat circuit. A bypass is set up in the ORC circuit to adjust the working medium flow rate via the expander to ensure efficient operation of the system. The invention improves the LNG cold energy recovery method based on the existing ORC cycle. The three-fluid heat exchanger and the regenerator could make full use of the cold energy provided by the LNG regasification process, reduce the thermal stress caused by the large temperature difference, alleviate the working load of the evaporator, and thus improve the heat to electricity conversion efficiency.

  • Patent number: 11449657
    Abstract: Area and routing overhead issues of traditional anamux incorporation in a semiconductor device are overcome by placing a functional anamux block on top of an I/O pad. In some embodiments, multiple anamux blocks can be stacked either vertically or placed on neighboring I/O pads for horizontal stacking. Embodiments provide the anamux blocks as the same width as the I/O pads and the width is optimized to minimize padring height. In some embodiments, a power/ground I/O (PGE) bond pad architecture is enabled by the incorporation of both I/O pad and anamux blocks in the same region, providing two bonding regions, which can further reduce chip area. Some embodiments also permit routing of signals through the anamux block to neighboring blocks and the I/O channels.

  • Patent number: 11296716
    Abstract: A multi-branch analog multiplexer (anamux) includes protection circuitry to help dissipate both positive and negative injected current without increasing the size of hardening transistors in each branch, thereby avoiding increased leakage current and enabling an analog to digital converter to operate with the required accuracy. The protection circuitry is tied to the body of the hardening transistor to lower the threshold voltage of the hardening device, thereby enabling the hardening device to handle more of the injected current.
