Interchangeable wire drive for wire feeder and spool gun

A modular welding wire feed drive for use in a welding system. The welding wire feed drive is designed to be detachably connected to the welding wire feed system of the welding system. The welding wire feed drive includes a drive housing designed to be detachably connectable to the welding wire feed system, a wire contact arrangement designed to controllably feed welding wire through the welding wire feed drive, and a drive motor that is connected to or interconnected to the wire contact arrangement to at least partially drive the wire contact arrangement.

On-off implant for supporting the tongue

The present invention provides an implant for stabilizing the tongue, including: a first anchoring portion for securing a first end of the implant with the mandibula; a control portion connected with the anchoring portion, configured for selectively activating the implant; a flexible portion connected at its proximal end with the control portion, the flexible portion having three-dimensional flexibility in a non-energized state and the flexible portion having a lesser three-dimensional flexibility in a energized state, the flexible portion being selectively switchable between the non-energized and energized states by the control portion, wherein the flexible portion can be an electroactive polymer element having: a composite layer having a polymer substrate and a biocompatible conductive material, wherein the composite layer also can be opposing surfaces; and a conductive polymer layer disposed on at least one of the opposing surfaces of the composite layer; and a second anchoring portion connected with the flexible portion, the second anchoring portion being configured for connecting the implant with the base of the tongue. Some embodiments include a housing designed to conform to the shape of the palate. Some embodiments include an attachment element to secure the device to tissue. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.

Frequency selective surface structure with wide passband and ultra-wide stopband

The invention relates to a frequency selective surface structure with wide passband and ultra-wide stopband. The frequency selective surface structure comprises a fine square ring array layer, a spiral meander line array layer and a thick square ring array layer, wherein the fine square ring array layer is etched on an upper surface inner side dielectric plate, the spiral meander line array layer is etched on an intermediate metal layer lower side dielectric plate, the thick square ring array layer is etched on a lower surface outer side dielectric plate, an upper side foam material interlayer is further arranged between the upper surface inner side dielectric plate and the intermediate metal layer lower side dielectric plate, and a lower side foam material interlayer is further arranged between the intermediate metal layer lower side dielectric plate and the lower surface outer side dielectric plate. The frequency selective surface structure has the advantages of small unit size, small thickness, low transmission loss, wide passband, good out-of-band rejection, further has the beneficial effects of ultra-wide stopband, wide electromagnetic wave scanning angular domain and stable scanning along azimuth angle of frequency response, and can be widely applied to antenna housing design in platforms such as radars, satellite communication and aircrafts.
