Apparatus for high-volume, high speed ultrasonic cutting or slitting comprising a blade having first and second cutting edges suspended from a reciprocating head, cantilevered over a conveyor supporting and advancing the food product, with the blade including first and second cutting edges on respective opposite sides thereof to cut the food product transversely. The head is preferably controlled for automated operation by an electronic controller to reciprocate transversely at a selected speed and a selected frequency within predetermined ranges over food product advancing on the conveyor. The blade preferably oscillates ultrasonically, and preferably at a frequency of approximately 20,000 Hz. The first and second cutting edges are preferably downwardly convergent, defining an included angle greater than 60 degrees and less than 90 degrees. In one particular embodiment, the internal angle is 70 degrees. In another embodiment, the angle is about 60 degrees. The blade may have a linear translating velocity of 25 to 35 inches per second, and more specifically may have a transverse velocity of approximately thirty inches per second. The apparatus may be used in high-speed, high-volume commercial food production operations for automated cutting of cheese products and other food products from large chunks, slabs and the like into smaller portions, and may also be used in other applications.

The invention relates to a multi-component converted wave static correction method by using surface waves, which comprises a step of solving stratigraphic classification and transverse wave velocity of a superficial layer through the extraction of the surface waves and the inversion of frequency dispersion curves based on Rayleigh surface waves in a shot record, so as to accurately calculate static correction quantity of detection points of converted waves. The test processing on two-dimensional three-component of a certain block in Daqing shows that a transverse velocity non-uniform body of the superficial layer generates a larger static correction time difference; and the processing on three-dimensional three-component data of a certain coal mine in Huainan shows that the static correction time difference of over 20 milliseconds can also occur due to the low and transversely non-uniform transverse wave velocity even in a flat plain terrain, and for a coalfield high-resolution seismic exploration to recognize minor faults of about 3 meters, the static correction time difference is a non-ignorable error. Application tests in three-component seismic data processing in two regions achieve a better processing effect and prove that the multi-component converted wave static correction method by using the surface waves is a feasible method.

The invention discloses a method and system for spraying control of a multi-rotor UAV based on speed detection. The method includes the following steps: detecting the flight speed and direction of the UAV; Cross decomposition, determine the sub-velocity V1 towards the nose and the sub-velocity V2 in the transverse direction; according to the sub-velocity V1 towards the nose and the sub-velocity V2 in the transverse direction, control a part of the water pumps to turn on and turn off the other part of the water pumps. The beneficial effect of the method is that the plant protection materials are made to fall behind the UAV without falling on the UAV, so that the lifespan of the UAV is not shortened, the crops are not damaged, and the plant protection materials are saved. The system includes: a flight data detection unit, a vector decomposition unit, and a control unit. The beneficial effect of the system is to realize the control of the atomization degree of plant protection materials, and to adjust different fog particles according to different crops, so as to achieve the purpose of not damaging the crops.
