A pneumatic ball launcher includes a tube, a ball pathway unit, a push unit, a holding unit, an airway unit and a pneumatic unit. The ball pathway unit is used for connecting one end of the tube and wrapping part of a ball channel of the tube. The push unit includes a push bar, a slide base, a first driver and a second driver. The holding unit, detachably connected with the push unit, is used for holding the ball pushed by the push bar. The airway unit is connected with the holding unit. The pneumatic unit includes a valve mechanism, a pneumatic cylinder and a gas tank. When the valve mechanism opens to allow the gas tank to discharge into the holding unit via the airway unit, the ball held by the holding unit would be ejected out of the tube.

The woven textile has a first end and an opposite second end. A longitudinal direction is defined by the first end and the second end. The woven textile includes an upper layer, a lower layer, and at least one binding thread. The upper layer includes at least one first braid woven by a plurality of filaments and extending in a meandering way to form a plurality of hollow portions. The lower layer includes at least one second braid woven by a plurality of filaments and extending in a meandering way to form a plurality of hollow portions. The binding thread fixes the first braid and the second braid together by weaving so that the upper layer and the lower layer are positioned by the binding thread.

A method for producing an artificial sebum film is provided with in raw material component and relative ratio, 78.4%-2% of triglyceride, 1%-15% of wax and ester, 20%-35% of squalane, 0.1%-7% of free fatty acid, 0.1%-6% of phospholipid, 0.1%-10% of cholesterol ester, 0.1%-10% of cholesterol, 0.1%-10% of antioxidant and 0.1%-5% of cellular activity regulator. The invention modifies the proportion of raw material composition of the artificial sebum film to reduce the negative effect generated by oxidation, and increase the proportion of squalane, so that the skin under high pollution can restore to the normal equilibrium state. Further, antioxidants and cellular active regulators are added to prolong the oxidation time of artificial sebum film and replenish the adenosine triphosphate in the cells.

A wireless communication device includes a housing and an antenna assembly. The antenna assembly includes a base board, a feed member electronically connecting with the base board to carry an electrical current, and a radio member including a first radio portion, the first radio portion defining a first slot. The radiator couples with the feed member, inducing an electrical current in the first radio portion. The radio member is electronically connected to the base board through the metal housing, enabling the induced electrical current to flow through the first radio portion, the metal housing, and the base board to form a current loop. The induced electrical current flows through the first slot to excite a first resonance mode, enabling the antenna assembly to receive/transmit a first wireless signal.

A blue LED device has a transparent substrate and a reflector structure disposed on the backside of the substrate. The reflector structure includes a Distributed Bragg Reflector (DBR) structure having layers configured to reflect yellow light as well as blue light. In one example, the DBR structure includes a first portion where the thicknesses of the layers are larger, and also includes a second portion where the thicknesses of the layers are smaller. In addition to having a reflectance of more than 97.5 percent for light of a wavelength in a 440 nm-470 nm range, the overall reflector structure has a reflectance of more than 90 percent for light of a wavelength in a 500 nm-700 nm range.
