Patent number: 11957712Abstract: An application of a hydrogel in the preparation of products for the treatment of bacterial infection is disclosed. Ferrous ion was used in the antibacterial activity test of Staphylococcus aureus and showed a strong bactericidal effect, which the survival rate of Staphylococcus aureus is less than 0.001%, as well as the survival rate of methicillin-resistant Staphylococcus aureus (MRSA) was less than 0.01%. Ferrous ion hydrogel was used for the treatment of keratitis and skin wound infection. Ferrous ion hydrogel for the treatment of keratitis and skin wound infection, which can significantly reduce the risk of pulmonary MRSA infection, prevented the dissimilation of MRSA to the lung, and alleviated systemic inflammation in the body in a timely and effective manner, revealing the therapeutic potential of ferrous compounds for treatment of Staphylococcus aureus infections, including MRSA.Type: GrantFiled: April 19, 2023Date of Patent: April 16, 2024Assignee: SHAANXI UNIVERSITY OF SCIENCE & TECHNOLOGYInventors: Liangbin Hu, Haizhen Mo, Xiaohui Zhou, Hongbo Li, Dan Xu, Zhenbin Liu, Zhen Wang

Patent number: 8811545Abstract: Interference in a received orthogonal frequency division multiplexing (OFDM) symbol, modulated according to selected constellation points sk, is reduced. The symbol includes a set of pilot signals and a set of data signals yk, where k is a number of consecutive subcarriers used for the pilot and the data signals. The pilot signals are thresholded to detect interfering pilot signals, which are then erased. Channels ?k are estimated using remaining pilot signals. The set of data signals are decoded based on the estimated channels ?k, and, for each bit bi in the set of data signals, a logarithmic likely ratio (LLR) log ? ? s k : b i = 0 ? 1 ? y k - H ^ k ? s k ? 2 ? s k : b i = 1 ? 1 ? y k - H ^ k ? s k ? 2 is determined. The LLR is an indicator of the likely interference.Type: GrantFiled: November 8, 2011Date of Patent: August 19, 2014Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: Ramesh Annavajjala, Liangbin Li, Philip Orlik
