Patent number: 11857635Abstract: The disclosure discloses a linker compound, a polyethylene glycol-linker conjugate and a derivative thereof, and a polyethylene glycol-linker-drug conjugate. The linker compound as well as the conjugate thereof with the polyethylene glycol and the derivative thereof may be used for modifying a drug, and a modification reaction is simple and easy to carry out. Moreover, a reaction yield is high, and an application range of the modified drug is wide. The modified drugs gradually degrade from a chain of the conjugate in vivo, and may stay in a lesion (such as a cancer site) for a longer period of time, achieving purposes of sustained and controlled release, reducing an administration frequency, and greatly improving a bioavailability of the drug and a patient compliance.Type: GrantFiled: March 30, 2020Date of Patent: January 2, 2024Assignee: JenKem Technology Co., Ltd.

Patent number: 10666325Abstract: A method for a near-field communication (NFC) tag to perform NFC and wireless power transfer (WPT) with an NFC reader, the NFC tag having an antenna resonant circuit, of which a quality factor (Q-factor) is no lower than 50 in a high-Q mode of the NFC tag, and no higher than 25 in a low-Q mode of the NFC tag. The method includes continuously preforming steps of detecting an NFC radio frequency (RF) field generated by the NFC reader, measuring strength of the NFC RF field, operating in the high-Q mode for the WPT upon determining that the strength of the NFC RF field is larger than a predetermined threshold, operating in the low-Q mode for the NFC upon determining that the strength of the NFC RF field is smaller than the predetermined threshold, and transmitting a response back to the NFC reader.Type: GrantFiled: March 17, 2017Date of Patent: May 26, 2020Assignee: NAN JING QIWEI TECHNOLOGY LIMITEDInventors: Ruogu Zhou, Qingbin Wang
