5results about How to "Reduce interception" patented technology

The application discloses a kind of mountainous area highway slope rockfall protection equipment, including supporting mechanism;The supporting mechanism includes protection plate, and further include at least one first linear degree of freedom;At least four The protection plate is hinged between each other and is folded mutually;The technology of the application can flexibly unfold and adjust the position, angle and form of protection plate according to actual situation by the design of supporting mechanism, abutting mechanism and carrying mechanism.This makes the protection device can adapt to different shapes of slope and various rockfall angle, improves the overall adaptability.M type of unfolding mode makes impact force more evenly distributed on each folding layer, thereby reducing the risk of damage caused by excessive local stress.This helps to prolong the service life of protection plate, reduces maintenance cost.M type of unfolding mode makes the side with acute angle face the side of mountainous area slope rockfall, this design can better intercept and block rockfall.

The invention discloses a DNS (Domain Name Server) iterative query method and a DNS iterative query product, and aims to solve the problem that a user query behavior is easy to track and analyze due to the fact that user privacy protection is not fully considered when a DNS query is processed in the prior art. In the process of querying the superior authoritative server of the domain name upwards step by step through the DNS resolver, the QNAME sent each time is a reduced domain name of an original complete domain name, and the QTYPE is other query types different from the original query type; the QNAME sent to the final authoritative server is the original complete domain name, and the QTYPE is the original query type. According to the method, the user privacy protection is enhanced by reducing the data transmission quantity, and the number of times of transmitting complete information of the user to the outside is reduced by minimizing the query domain name and confusing the query types, so that the risk that the privacy of the user is exposed is effectively reduced.

The invention relates to the technical field of off-line interaction, and provides an off-line voice cross-device control method and device, equipment, a medium and a product, the method is applied to voice equipment, and the method specifically comprises the following steps: in an off-line state, obtaining a user voice instruction; a controlled device and a control instruction are determined according to the user voice instruction; the control instruction is sent to the controlled device, and an execution result is fed back to the user according to the state of the controlled device within the preset time; through the above mode, on the premise that the equipment is not networked, cross-machine control of other equipment can be realized through offline voice recognition and offline communication technologies, more application scenes are adapted, and more convenience and security are provided for users.
