  • GRAFT COPOLYMERS, METHODS OF FORMING GRAFT COPOLYMERS, AND METHODS OF USE THEREOF
    Publication number: 20220008346
    Abstract: A graft copolymer and a method of delivering an active agent to a subject are provided. The graft copolymer includes a polymer backbone, a hydrophilic segment grafted to the polymer backbone, a pH-responsive segment grafted to the polymer backbone, and an endosomal disruption segment grafted to the polymer backbone. The method of delivering an active agent to a subject includes encapsulating the active agent with the graft copolymer and administering the encapsulated active agent to the subject.

  • Optimizing the rate in a Li-Fi system
    Patent number: 9544053
    Abstract: The invention relates to a method for optimizing the data rate, in a wireless communication system comprising a LED forming an emitting device, and a photodetector forming a receiving device. For a given value of a DC component of the supply signal of the LED, the modulation amplitude of an AC component of this supply signal is adjusted step by step, so as to improve the transmission quality of the signal provided by the LED and received by the photodetector. The invention also relates to an optimization module implementing such a method. Alternatively, the modulation amplitude of the AC component of the supply signal is set, and the value of the DC component is adjusted step by step.
