Cutting, scoring and perforating die set and method

An apparatus for substantially-simultaneously die cutting cardboard sheets for forming folded cardboard cartons and an openable and closable tab. The improvement resides in a die set comprising a plurality of cutting knives projecting from a base, the cutting knives being fixed into a preselected pattern of grooves within the base. The die set may further include at least one transversely-spaced-apart pair of a die blade and a perforating knife mounted in the base, in which either or both of the die blade or the perforating knife is "jackably mounted" for selective manual raising or lowering. The die set may alternatively further include at least one transversely-spaced-apart pair of a die blade and an anvil mounted in the base, in which either or both of the die blade or the anvil is "jackably mounted" for selective manual raising or lowering. In either case, the base is secured to a back-up plate. Either die set is used in a double platen die cutting apparatus in which the die set is mounted on the upper platen and in which the lower platen is movable towards the upper platen. The perforating knife may still further alternatively be mounted on the lower platen. In all cases, the die blade and the perforating knife converge to a common focal or starting point when the platens are urged towards one another with the cardboard therebetween, to provide for a common starting point for the operable and closable tab.

A Method for Measuring Ultrasonic Echo Propagation Time

The invention discloses a method for measuring the propagation time of an ultrasonic echo. The propagation time can be obtained by adopting corresponding fundamental wave signals aiming at different flow rates to carry out cross-correlation operations and search the peak values of cross-correlation functions. As the fundamental wave signals at different flow rates are actual data extracted in a dynamic measurement process, the fundamental wave signals have higher precision and are capable of reflecting actual conditions. The fundamental wave signals at corresponding flow rates are adopted to carry out the cross-correlation operations, thereby, the propagation time of dynamic ultrasonic signals is calculated, the measuring errors are greatly reduced, and the uncertainty of a measuring result is reduced. Moreover, the cross-correlation operations are carried out by utilizing the similarity among the signals, the higher the similarity is, the higher the precision, and a non-correlation noise suppression effect is obvious. The invention also provides a novel fundamental wave extraction mode, which is characterized in that the fundamental wave signals are accurately obtained through a set energy constraint boundary. Compared with the mode that a threshold method is adopted to obtain the arrival time of the echo so as to extract the fundamental wave signals, the initial segments of the fundamental wave signals extracted by the novel fundamental wave extraction mode disclosed by the invention are more accurate.

Method and device for starting one-hand operation mode

The invention discloses a method and a device for starting a one-hand operation mode. The method comprises the steps as follows: using a sensor to judge whether a right hand or a left hand holds a mobile terminal and detecting whether an edge triggering gesture is available; starting the corresponding one-hand operation mode when detecting the edge triggering gesture and the edge triggering gesture is consistent with a judging result of the sensor. Due to the fact that the sensor is used for judging whether the right hand or the left hand holds the mobile terminal, and detecting whether the edge triggering gesture is available, the method does not start the one-hand operation mode when the edge triggering gesture is unavailable, and can be further used for judging whether the edge triggering gesture is consistent with the judging result that the right hand or the left hand holds the mobile terminal when detecting the edge triggering gesture, and does not start the one-hand operation mode when the edge triggering gesture and the judging result are not consistent, and starts the corresponding one-hand operation mode only when the edge triggering gesture and the judging result are consistent. Thereby, the method and the device not only avoid a misoperation, but also accurately and fast start the one-hand operation mode to enable the operation to be more accurate and convenient.

The invention belongs to the technical field of development equipment of ocean resources and discloses a deep-sea triggered active type creature trap and a control method. A completely-open type trapping inlet is formed through inserting a pin of a driving mechanism into a center fixing shaft and a center moving sleeve and setting relative positions of a moving frame and a fixing frame; and when the trap performs deep-sea creature trapping on a seafloor, a trigger mechanism is in an open state, the trigger mechanism is in an operating state for closing the trap when bait wrapping the outer side of the trigger mechanism stresses a certain snap-in force, and response is transferred to the driving mechanism in time through a cable. According to the deep-sea triggered active type creature trapand the control method, by adopting the completely-open type trapping inlet, the possibility that deep-sea creatures enter a trapping area is greatly increased; and by adopting the active trigger mechanism, creatures such as fishes can be specifically trapped, timely triggering can be achieved, and thus, rapid control and response are achieved, so that the creature trap has the trapping characteristics of stability, accuracy and rapidness, the pertinency is relatively high, and the success rate of trapping is relatively high.
