The device and method for the transmission of data and electric energy between the key and the cylinder of a lock comprises a first electromagnetic circuit associated with the key, and a second electromagnetic circuit associated with the cylinder, the first and second electromagnetic circuits have co...
A lock of the type composed of a casing provided with a sliding latch by means of the rotation of the corresponding removable key, which engages with the hole of the fastener integral with the upright of the frame, characterized in that the lock comprises a blocking device that prevents extra...
The feasibility of dual parameter sequentially controlled ‘lock-and-key’ system was verified with PAGE analysis by mixing the hairpin structure oligonucleotide (DNA primer) in ONV with the ‘locks’ (sgc8c and sgc4f aptamers) together and respectively (Supplementary Fig. 2a). Although sgc8c ap...
依次从所有的 Redis master 节点使用相同的 key、value 获取锁。 如果客户端从过半的 Redis master 节点获取到了锁,并且此刻的时间 B - 起始时间 A < 锁的失效时间 TTL,就会认为该客户端真正地获取到了锁。 如果客户端在上一步骤成功获取到了锁,那么剩余可持有锁的时间为 锁的失效时间 TTL - 上一步骤得到...
