Abstract: A method and system for generating a logarithmic non-uniform pseudo-random electromagnetic exploration signal including: constructing two or more basic unit signals, according to an exploration requirement, that are stairstep signals obtained by superposing in-phase periodic square wave signals, a frequency ratio between adjacent periodic square wave signals is 2, and the two or more basic unit signals meet the following requirement: if a lowest dominant frequency in a first basic unit signal is a fundamental frequency, lowest frequencies of the remaining basic unit signal are l×2m times the fundamental frequency, where l is an odd number except 1, and m is a natural number; and superposing the two or more basic unit signals to obtain a logarithmic non-uniform 2n sequence pseudo-random signal. A logarithmic non-uniform 2n sequence stairstep signal is constructed within a limited frequency interval, and requirements of prospectors for a higher frequency density within a specific frequency interval are met.

Abstract: A compensating mechanism includes a base unit, a transmission unit, an adjusting cap and a rotation setting unit. The base unit includes a grooved portion that includes a first groove and a second groove communicated with the first groove. The second groove includes a first end and a second end opposite to the first end. The first end is connected to the first groove. The first end and the second end have a height difference therebetween in an axial direction of the base unit. The transmission unit is disposed on the base unit. The adjusting cap is connected to the transmission unit. The adjusting cap drives the transmission unit to rotate when the adjusting cap is rotated. The rotation setting unit includes a movable element that is movably disposed on the transmission unit to be connected to the grooved element or to be separated from the grooved element.

Abstract: A video playing method includes: transmitting, in response to detecting a user input on a target control in a map display interface, a first acquisition request, the first acquisition request being used for acquiring target video data corresponding to the target control; receiving response information for the first acquisition request, and acquiring the target video data based on the response information; and displaying a video window on the map display interface, the video window being used for playing the target video data.

Abstract: An emergency call method is applied to a vehicle-mounted communications system. The emergency call method includes a telematics box activating a host function. The host function includes controlling a first transmission node and a peripheral connected to the first transmission node. The telematics box is connected to the first transmission node, and the telematics box performs data transmission with the first transmission node using the host function. The first transmission node is in a master node mode.

The atomization assembly comprises an atomization component and first electrodes, each first electrode comprises a base portion and a connecting portion, the connecting portion extends along a first direction of the electronic cigarette, and the base portion extends along a second direction basically perpendicular to the first direction. The battery assembly comprises second electrodes, each second electrode abuts against the base portion, and the second electrode extends in the first direction of the electronic cigarette and is deviated from the connecting portion. Good contact between the first electrodes of the atomization assembly and the second electrodes of the battery assembly can be ensured.

Abstract: A broken pipe extraction device includes first, second, and third pressure plates, a fixing member, a fastening member, and a needle. The first pressure plate includes a first perforation and a second perforation connected to the first perforation. The second perforation passes through a side wall of the first pressure plate. The second pressure plate faces the first pressure plate. Projecting portions of the first perforation and the second perforation on the second pressure plate overlap. The third pressure plate includes a through hole. The third pressure plate is detachably received in the first perforation and the second perforation. The fixing member mounts on the second pressure plate and faces the first perforation and the second perforation. When the third pressure plate is received in the first and second perforations, the through hole faces the fixing member.
