  • Patent number: 11753066
    Abstract: A multifunctional electric recirculating ball steering system for commercial vehicles and its control method are described. The system comprises three modules: an electric power module, a mechanical transmission module, and a control module. The system introduces a dual-rotor motor and a common power motor, working together to act on the input end of a recirculating ball steering gear. The dual-rotor motor offers high redundancy, increased output torque, and improved reliability for control-by-wire operations. A fork assembly enables synchronous and asynchronous rotation of the dual rotors, achieving both steer-by-wire and electric power steering functions. Leveraging the high reduction ratio capability of the recirculating ball steering gear maximizes power torque and simplifies the system architecture while ensuring reliability in both traditional control and control-by-wire functionalities.

  • Patent number: 9303055
    Abstract: A method of modulation of synthesis capacity on and cleavage properties of synthetic oligomers from solid support is described. The method utilizes linker molecules attached to a solid surface and co-coupling agents that have similar reactivities to the coupling compounds with the surface functional groups. The preferred linker molecules provide an increased density of polymers and more resistance to cleavage from the support surface. The method is particularly useful for synthesis of oligonucleotides, oligonucleotides microarrays, peptides, and peptide microarrays. The stable linkers are also coupled to anchor molecules for synthesis of DNA oligonucleotides using on support purification, eliminating time-consuming chromatography and metal cation presence. Oligonucleotides thus obtained can be directly used for mass analysis, DNA amplification and ligation, hybridization, and many other applications.
