摘要： A cable tie including a belt, a base, a restricting part, and a controlling part is provided. The belt has a contacting side. The base is connected to a first end of the belt and has a through-hole. The restricting part is connected to the base and is located in the through-hole. The controlling part has a connecting portion, and a protruding portion and a pressing portion away from the connecting portion, and the connecting portion is connected to the base. When the belt passes through the through-hole, the contacting side defines a tying area for accommodating a tied object, and the protruding portion protrudes into the tying area. When the tied object pushes the protruding portion towards outside the tying area, the pressing portion presses the restricting part to restrict a movement of the belt.

摘要： A switch device includes a first connection interface, a second connection interface, an video output interface, a control module and a processing module. The first connection interface receives a first video and the second connection interface receives a second video. The video output interface outputs an integrated video. The control module receives a control signals including a position data. The processing module generates the integrated video based on the first video and the second video. The integrated video includes a first sub-image having a first depth and a second sub-image having a second depth respectively corresponding to the first video and the second video. When the position data falls within an overlapping area of the first sub-image and the second sub-image, the processing module outputs the control signal to one of the first connection interface and the second connection interface based on the first depth and the second depth.

摘要： A switching device includes multimedia input interfaces for respectively receiving multiple multimedia signals, a switching unit electrically connected to the multimedia input interfaces, a multimedia output interface, an electrical characteristics modulator, and a controller. The switching unit outputs a selected multimedia signal according to a first control signal. The multimedia output interface includes a multimedia signal terminal for outputting the selected multimedia signals and a non-signal terminal. The electrical characteristics modulator changes an electrical characteristic of the non-signal terminal according to a second control signal.
