Abstract: A portable heating sterilization bag for face mask and cloth products includes a bag container. The bag is capable of holding and containing face masks. At least one of heating plate installed on one inner surface in the bag and being made of god conductor material of heat; a heat source is for heating the at least one heating plate; the heat source is attached to the at least one heating plate and serving to control the internal temperature of the bag. If the power switch is turned on, the heat plate heats the contained face mask or cloth product to produce the effect of face mask or cloth product disinfect and sterilization. The heating plate is made of metal or non-metal material and it can be rigid or flexible.

Abstract: A multi-robotic live production and webcast videographic system includes at least one videographic robot operating automatically and performing videography on spot through specific rules or by its own ability after learning; a main controller being a remote control device for receiving video or voice messages from at least one videographic robot; the receiving messages and production data of the main controller being stored in an videographic database; and at least one operation mode unit for determining operation modes of the videographic robot so that the videographic robot acts according to the operation mode; the operation mode unit including an operation mode database which stores various specific operation modes including a logic mode, an AI mode and a scenario mode so that the videographic robot may move to a desire position and adjust the shooting angle according to a selected operation mode.

Abstract: An adjustment device including a camera is connected to a display device. An image of a predetermined image displayed on the display device, and an image of a standard color image are captured by the camera. First chrominance differences and first luminance differences between the image corresponding to the standard color image and the standard color image are computed. Second chrominance differences and second luminance differences between the image corresponding to the predetermined image and the predetermined image are computed. Third chrominance differences between the first chrominance differences and the second chrominance differences, and third luminance differences between the first luminance differences and the second luminance differences are computed. According to third chrominance differences and third luminance differences, first adjustment data is obtained. The first adjustment data is sent to the display device. According to the first adjustment data, c.

Abstract: A foldable bicycle with a large wheel and a small wheel contains an upper rod including one end connected with a side of a supporting post and another end coupled with a first tubular member, the first tubular member including a through hole; an axial shaft inserted into the through hole of the first tubular member of the upper rod and rotating in the through hole; the axial shaft also inserted into an orifice of a second tubular member of a lower rod and rotating in the orifice; wherein the axial shaft includes a bracket extending downward therefrom; the small wheel is axially disposed on a distal end of the bracket, and the large wheel is axially disposed on a distal end of a rear support; when the axial shaft rotates 180 degrees rearward, the small wheel is moved to be close to the large wheel.

Abstract: A rotating mechanism. The rotating mechanism comprises a fixed member, a first rotating member, a second rotating member, a restricting member and a first resilient element. The second rotating member has an abutting portion, and the restricting member movably connects to the first rotating member and contacts the abutting portion. The first resilient element connects the fixed member and the first rotating member. Moreover, the first resilient element provides a spring force rotating the first rotating member, wherein the restricting member rotates along with the first rotating member and pushes the abutting portion to rotate the second rotating member.

Abstract: A rotating mechanism. The rotating mechanism comprises a housing, a first rotating member, a second rotating member, a restricting member and a resilient element. The housing has a curved inner wall, a first positioning portion and a limiting member. The first rotating member is rotatably disposed in the housing and has a second positioning portion. The second rotating member is rotatably disposed on the first rotating member. The restricting member abuts the limiting member and has a curved outer edge, a first end and a second end. The profile of the curved outer edge approximately corresponds to that of the curved inner wall. The first end is rotatably connected to the first rotating member. The resilient element is connected to the housing and first rotating member. The first rotating member rotates within a predetermined angle by means of the resilient element, first positioning portion and second positioning portion.
