Abstract: The present application provides to a media dosage unit (300) for shot peening. The application also presents methods of using and making the media dosage unit. The media dosage unit comprises a flow sensor (304) for measuring flow rate of solid particles; and a connector on the flow sensor for coupling the flow sensor to a shot circulation conduit (306). The present application also relates to a media flow valve (316) for the media dosage unit for shot peening. The application additionally discloses a method of making or assembling the microwave media flow sensor.

Abstract: A shot peening valve controller comprises a hub connector configurable for connecting or operating one or more shot peening valve; a microprocessor that is connected to the hub connector; and a human-machine interface that is connected to the microprocessor. The human-machine interface is configured to operate the one or more shot peening valves respectively.

Abstract: A hydrogel composition and a hydrogel lens are provided. The hydrogel composition includes a hydrophilic monomer, a cross-linker, an initiator, and a rotaxane compound. In the hydrogel composition, a content range of the hydrophilic monomer is between 60 wt % and 99.85 wt %, a content range of the cross-linker is between 0.01 wt % and 1 wt %, a content range of the initiator is between 0.01 wt % and 2 wt %, and a content range of the rotaxane compound is between 0.1 wt % and 15 wt %. The rotaxane compound further includes at least one cyclic molecule and at least one linear molecule threading through the at least one cyclic molecule, and a weight ratio of the rotaxane compound relative to the hydrophilic monomer is between 1:6 and 1:99.

Abstract: A control valve (100) comprises a conduit (102), a controller (104), a sensor unit (106; 146, 148), a cylindrical housing (112) and one or more regulating columns (124, 126). The conduit further comprises a hollow cylindrical body (114) and two smaller and shorter cylindrical extensions (116, 118) for the insertion of the regulating columns which are orthogonal to the hollow cylindrical body and provide a contactless means to control the flow of the medium (101) in the conduit.
