Abstract: A device for forming and inspecting an end piece on a screw of a fastening ring includes a deck with a rotary disk, a control unit for driving the rotary disk, an inspection unit, a first riveting machine, an arm unit and a conveyor respectively and electrically connected to the control unit. The inspection unit, the first riveting machine, the arm unit and the conveyor are located around the rotary disk. Multiple holding devices are connected to the rotary disk and each holding device holds two fastening rings. The screw of each fastening ring is formed with an end piece by the first riveting machine, the arm unit and the conveyor. The inspection unit inspect the formation of the end piece and classifies defective products and non-defective products.

Abstract: A barcode scanner comprises a compensating light source, an image capturing module and a processor. The compensating light source is used to emit a compensating light. The image capturing module is used to capture an original image including an object and to capture a second image under the compensating light. The processor is coupled with the compensating light source and the image capturing module. The processor generates a depth information of the object according to the original image, controls intensity of the compensating light according to the depth information, controls the image capturing module to capture a second image when the compensating light source emits the compensating light, obtains a target information corresponding to a target object according to the depth information, obtains a target image by mapping the target information onto the second image, locates a barcode and analyzes an information of the barcode according to the target image.

Abstract: A pliers with quickly adjustable gripping jaws includes a first jaw and a second jaw. The first jaw is deposited on a first hand shaft. The second jaw is pivoted on a second hand shaft. An adjusting set is set up between the hand shafts. The adjusting set includes a control lever and a sliding lever. The control lever has first teeth and the sliding lever has second teeth. The first and second teeth are engaging with each other. An elastic member is located between the control lever and the second hand shaft. A spring is locked between the sliding lever and the second hand shaft. The elastic member and the spring are serving for control lever and sliding lever to back their beginning respectively. Therefore, a user only clamps the hand shafts of the pliers to adjust the gripping jaws quickly in order to clamp objects with different sizes.

Abstract: A switch includes a call record table recording at least one outgoing call. When the switch receives an incoming call, the switch searches the call record table to find a mapping outgoing call with a destination telephone number the same as a source destination telephone number of the incoming call. Then the switch obtains a communication line number of the mapping outgoing call in the call record table, and sends a ringing signal to a local telephone corresponding to the obtained communication line number.

Abstract: A multimedia terminal adapter (MTA) electronically connected to a call management server and phone sets configured in at least two different networks, includes a receiving module and a control module. The control module drives the phone sets configured in the at least two different networks to ring when the receiving module receives a call from the call management server, receives an off-hook signal from one of the phone set configured in a network, controls other phone sets configured in other networks to stop ringing, and sends the off-hook signal and Internet protocol (IP) port information of the off-hook phone set to the call management server.
