Abstract: A measurement assistance system and method are provided. The measurement assistance system includes: a measurement platform, having an operation area configured for a to-be-measured object and a measurement tool to be placed; a camera, arranged on the measurement platform and configured to obtain a measurement image; and a server module, electrically connected to the camera and configured to execute a measurement tool identification program, a measurement part identification program, and a measurement posture identification program according to the measurement image, and determine whether a measurement tool appearance image, a measurement part image, and a measurement posture image are correct. The server module has a processing unit. When the measurement tool appearance image, the measurement part image, and the measurement posture image are all correct, a measurement result is generated according to measurement data.

Abstract: A lamination chuck for lamination of film materials includes a support layer and a top layer. The top layer is disposed on the support layer. The top layer includes a polymeric material having a Shore A hardness lower than a Shore hardness of a material of the support layer. The top layer and the support layer have at least one vacuum channel formed therethrough, vertically extending from a top surface of the top layer to a bottom surface of the support layer.

Abstract: An automatic material changing and welding system for stamping materials includes a welding transfer sliding table and a welding platform. The automatic material changing device further includes a feeding system. The feeding system includes a double-head uncoiling machine, an automatic feeding machine and a flattening machine. The automatic material changing device is used for automatic feeding for a stamping machine. The system triggers a material changing signal through a sensor to control and integrate the welding transfer sliding table and the welding platform to act to execute a welding procedure, so that the stamping materials are in welding connection with new and old coiled materials through a welding connection plate to realize continuous production operation of an automated stamping production line.

Abstract: A hand tool for bolts fastening includes a block-shaped jig body, a first bolt hole is disposed in the jig body laterally and a second bolt hole is disposed in the jig body longitudinally, an end of the second bolt hole is in communication with the first bolt hole, the second bolt hole allows a packing bolt to pass through and be screwed, a hemispherical suppression portion is disposed at an end of the packing bolt, the first bolt hole allows a to-be-fastened bolt to be screwed, the suppression portion of the packing bolt is pressed down on a selected position of the bolt, to cause a crest at the selected position to expand outward, so that interference occurs when the bolt is screwed with a bolt hole or a nut, to increase a torque force required to make the bolt come off.

Abstract: A cutting fluid digital monitoring and management system and method are provided, applicable to a computer numerical control (CNC) machining device. The CNC machining device has a cutting fluid tank configured to accommodate a cutting fluid. The cutting fluid digital monitoring and management system includes: a detection tank, configured to extract a cutting fluid from the cutting fluid tank through a motor and an electrically controlled water valve; a concentration sensing module, a pH sensing module, a water hardness sensing module, and a temperature sensing module, respectively configured to obtain a concentration, a pH value, a hardness, and a temperature of the cutting fluid; a processing module, configured to generate a monitoring integration value, compare the monitoring integration value with a standard model, and generate an adjustment signal; and an adjustment module, configured to actively adjust a variable parameter of the cutting fluid according to the adjustment signal.

Abstract: A voice over Internet protocol (VoIP) device for providing VoIP service for a telephone includes a time detecting module and a time adjusting module. The time detecting module is operable to receive a dual tone multiple frequency (DTMF) signal, detect interrupt time of the DTMF signal, and determine whether the interrupt time is less than a predefined time interval. The time adjusting module is operable to adjust the interrupt time to the predefined time interval upon the condition that the interrupt time is less than the predefined time interval.

Abstract: A network device connected to a client includes a table-creation module, a transceiving module, a detecting module, and a translation module. The table-creation module creates an internal table and at least one external table, listing a plurality of real network parameters of the network device, and a plurality of virtual network parameters of the network device, respectively. The real parameters respectively corresponding to the virtual parameters. The transceiving module receives a packet from the network or the client, and forwards the packet. The detecting module detects whether the packet is a voice over Internet protocol (VoIP) packet, and further detects whether the VoIP packet is a VoIP control packet, or a VoIP data packet. The translation module translates network parameters of the VoIP packet according to a corresponding relationship between the internal table and the at least one external table. A packet forwarding method is also provided.

Abstract: A network device (10) communicates with other network devices with a plurality of loops, and includes a plurality of virtual ringing groups, a plurality of Ringer Equivalency Number (REN) loads (106), a receiving module (100), an assigning module (102), and a ringing module (104). Each virtual ringing group rings during an individually fixed ringing time interval. The REN loads are for generating ringing signals, and the number of REN loads is less than that of the loops. The receiving module receives a calling signal, and transmits the calling signal to one of the loops. The assigning module assigns the calling signal to one of the virtual ringing groups. The ringing module assigns one REN load to the loop with the calling signal according to the assigned virtual ringing group. A load assigning method is also provided.
