Abstract: Detecting an unauthorized wireless access point in a network uses a detector. A rogue access point detector receives an incoming data packet which is scanned for a time expiration value. The time expiration value may be a Time To Live (TTL) value as used in Internet Protocol data packet headers. It is determined whether the time expiration value is the same as a threshold time expiration value. If the time expiration value is not the same as the threshold value, it is determined whether the incoming data packet was routed through an authorized access point in the network. If it is determined that the packet is not being routed from an authorized access point, a security component in the network, such as a network administrator's workstation, is notified. During this process the time expiration value remains unchanged.

Abstract: A manufacturing method and a foaming manufacturing method of polymethyl methacrylate/silica composite material are disclosed. At first, synthesize silica by a sol-gel process. Then, prepare polymethyl methacrylate/silica composite material by bulk polymerization. At last, prepare polymethyl methacrylate/silica foam nanocomposite material from polymethyl methacrylate/silica composite material by a foaming method.

Abstract: The invention disclosed a striking type of entertainment performance apparatus with reactive sound-light comprising: a striking module provided on the lower part for interacting with the player, with a plurality of trigger striking region provided on the striking face; a plurality of dependent striking portion that spin or swing intentionally accompany the applied force; a lamplight reactive module, which is hung on the high part and includes a plurality of lamplight reactive region and a plurality of dependent reactive region, and respond to corresponding striking module by a plurality of driving device and lamplight device. Thus, the performer may hit the striking module to match the musical sound and rhythm so that the reactive module can respond with projection, twinkling, movement or rotation through various lamplight device to create sensual special effect of surrounding.
