Patent number: 11867320Abstract: In a polymeric microfluidic valve, an adhesion control surface with discrete micro- or nano-scale structured surfaces are separated by fluid filled voids at an interface between an elastomeric membrane seals against a substrate layer.

Patent number: 11860651Abstract: An adjustment position of a water output device is provided. A flow volume adjustment component of the water output device has a first position corresponding to a flow volume greater than zero; upon detecting that the flow volume adjustment component reduces the flow volume to that corresponding to the first position, a detection component sends a signal to a control component; and the control component-turns off an electronic waterway switch according to the signal. In this way, when the flow volume is reduced, the electronic waterway switch can be turned off by signal control, and in this case, the flow volume adjusted by the flow volume adjustment component is kept at a particular value, such that the next time water is output by a user using an electronic mode, the failure of water output would not occur.Type: GrantFiled: January 20, 2020Date of Patent: January 2, 2024Assignee: XIAMEN AXENT CORPORATION LIMITEDInventors: Yimin Fang, Dongsheng Yao, Guanjin Zhong
