  • Patent number: 10587082
    Abstract: The present invention discloses a network connection device. The network connection device includes a plug and a socket; the plug includes network cables, an encapsulation portion and a Universal Serial Bus interface; one end of the encapsulation portion is connected with the network cables, and the other end of the encapsulation portion is connected with the USB interface; and the socket is matched with the USB interface. Compared with the existing network connection device, the plug of the network connection device provided by the present invention is disposed by adopting the USB interface and particularly a Type-C interface and may be plugged forward and backward, so the network connection device not only is plugged conveniently, but also is small and exquisite, has a stable signal and does not cause an unstable network connection due to a failure of one signal pin to affect the signal transmission.

  • Publication number: 20190213946
    Abstract: The present invention relates to the field of display technologies, and provides an LED module comprising an LED array and a control circuit for driving the LED array to work. The LED array comprises multiple rows of LED units, each row of the LED units comprising multiple LED pixels integrating an red light-emitting grain, a blue light-emitting grain and a green light-emitting grain. The LED array is arranged in such a pattern that alternate rows aligned with each other, in which LED pixels of the same sequence number in adjacent two rows of the LED units are deviating one another in a vertical direction, thereby forming a structure in which the LED pixels in each row of the LED units is arranged deflecting from each LED respective LED pixels in an adjacent row of the LED units.

  • Publication number: 20190202075
    Abstract: A multi-purpose bayonet knife assembly mounts to the distal end of a firearm barrel to augment the firearm as a pike and detaches to operate as a knife, while also providing integrated utilitarian components having minimal moving parts. The assembly comprises a hilt, a cross guard, and a blade. The hilt has an integral flint and a snap-on hook. The hook detachably couples to the firearm barrel, and also serves to open a bottle. A sleeve houses the hilt. The blade is defined by a longitudinally extending edge defined by: a first serrated edge, a second serrated edge, an angled bevel, and a double-sided blade tip oriented about 30° above the longitudinally extending edge of blade. Blade includes metric and imperial scales, time dial, and compass. Blade forms a dowel hole, nut socket holes, and a longitudinally extending groove. The metallic composition of the blade serves as an antenna.
