  • Patent number: 12221475
    Abstract: Provided are a chimeric antigen receptor and an application thereof; said chimeric antigen receptor contains a domain which identifies any one of, or a combination of at least two of, the malarial protein VAR2CSA, a protein tag on malarial protein VAR2CSA, or a compound capable of labeling the malarial protein VAR2CSA. The chimeric antigen receptor can identify the VAR2CSA protein or the recombinant protein (rVAR2) of any one of, or at least two of, the domains of the VAR2CSA protein which can bind to placental-like chondroitin sulfate A (pl-CSA). The VAR2CSA protein or rVAS2 protein is capable of targeting several different types of tumor cells by means of binding to the pl-CSA on the surface of the tumor cell.

  • Patent number: 12221922
    Abstract: The present invention disclosed an Organic Rankine Cycle (ORC) power generation system utilizing LNG cold energy and dual-fuel marine engine waste heat. The ORC power generation system has a Liquified Natural Gas (LNG) loop, one or more ORC loop, and one or more waste heat recovery (WHR) loop. The LNG loop works as a heat sink, which provides cold energy for working medium condensation. The WHR loop, utilizing the waste heat from main engine jacket cooling water and engine exhaust gas, provides heat for working medium evaporation. The ORC loop may have a pump, a three-fluid heat exchanger, an expander, a power generator, a regenerator, a liquid-vapor separator, a liquid reservoir, a regulating valve, and an evaporator. A regenerator is arranged within the ORC loop between the expander and the three-fluid heat exchanger. The ORC loop may have one or more evaporator, which may recover the waste heat from main engine jacket cooling water and engine exhaust gas.

  • 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.
