Title: System and method for providing peer level access control on a network.
Inventor: ZENCHELSKY DANIEL N
IPC: H04L9/32
Filed: 1998-01-13
Abstract: A system and method for providing peer-level access control on networks that carry packets of information, each packet having a 5-tuple having a source and destination address, a source and destination port, and a protocol identifier. The local rule base of a peer is dynamically loaded into a filter when the peer is authenticated, and ejected when the peer is loses authentication. The local rule base is efficiently searched through the use of hash tables wherein a hashed peer network address serves as a pointer the peer's local rules. Each rule comprises a 5-tuple and an action. The action of a rule is carried out on a packet when the 5-tuple of the rule corresponds to the 5-tuple of the packet.

Title: Ultrasonic vibration-assisted grinding device for gears and operation process thereof
Inventor: YUCAN FU
IPC: B24B1/04
Filed: 2022-05-01
Abstract: The present invention relates to an ultrasonic vibration—assisted grinding device for gears and an operation. process thereof. A piezoelectric ceramic plate of the device generates high—frequency longitudinal vibration displacement under the excitation of electric signals from an ultrasonic generator; the vibration displacement is amplified, by a hollow tapered, amplitude transformer and transmitted, to a gear to be machined, that is fastened with a central fixing bolt; the hollow tapered amplitude transformer is designed with an annular vibration—isolating groove inside and a flange circumferentially; and a vibration—isolating groove is arranged for the flange. These structures ensure reduction of ultrasonic vibration effects in the mounting position of the central fixing bolt while enhancing vibration transmission effects of the contact face between the gear and the amplitude transformer. The device is simple in structures, and it is easy to achieve ultrasonic high—frequency micro—vibration machining effects for high—strength and high—precision gears.
