The present disclosure provides a pouch-type secondary battery, which comprises an electrode assembly, a packaging film. The packaging film comprises a first receiving portion, a second receiving portion, a third receiving portion. The third receiving portion is parallel to the first receiving portion, a portion of the electrode tab extends out of the third receiving portion. A joint location between the second receiving portion and the first receiving portion and a joint location between the second receiving portion and the third receiving portion each are formed with a bending angle, the bending angles are equal and each range from 130° to 160°. Because the bending angles in the range are relatively large, when the packaging film is tightly pressed, there is no need to apply a too large pressure on the second receiving portion and the third receiving portion, so the electrode tab is not easily damaged or even ruptured.

METHOD FOR DEFENDING AGAINST DENIAL-OF-SERVICE ATTACK ON THE IPV6 NEIGHBOR CACHE

Номер: US20120180130A1
Автор: AALDERS MICHAEL, LAHTI Patrik
Принадлежит: NORTEL NETWORKS LIMITED

A method of defending against a denial-of-service (DoS) attack on an IPv6 neighbor cache includes steps of determining a number of neighbor cache entries currently stored in the neighbor cache and then determining whether the number of entries exceeds a neighbor cache threshold that is less than a neighbor cache limit defining a maximum capacity of the neighbor cache. When the number of entries in the neighbor cache exceeds the neighbor cache threshold, stateless neighbor resolution is triggered. Stateless neighbor resolution entails sending a neighbor solicitation to resolve an address for an incoming packet without logging a corresponding entry in the neighbor cache. Additional techniques that complement the above method involve purging of neighbor cache entries designated as incomplete, prioritization of the entries based on trustworthiness, shortening the incomplete-status timer to less than 3 seconds, and curtailing the number of retransmissions of the neighbor solicitations. 123-.

The present invention provides a system and method to selectively negotiate different delivery styles for different types of packets sent from the Mobile Node to the Foreign Agent, which will allow the Mobile Node to negotiate a delivery style that will permit the Foreign Agent to transmit certain selected outbound traffic directly without reverse tunneling that traffic back to the home network. Specifically, the present invention allows the Foreign Agent to distinguish between certain types of BC/MC packets that are designated to be processed and routed to their destinations by the Foreign Network directly, as opposed to reverse tunneling the outbound traffic from the Foreign Agent back to the Home Agent on the home network. By selecting processing by the Foreign Network, the efficiency of the system will improve because the transmission of outbound traffic and inbound responses will not need to be tunneled through the Home Network. 1.

A resin composition which comprises a polyester and is free from a smell produced from a free isocyanate compound. The resin composition comprises a polyester (component A) whose end is modified and a compound including a cyclic structure having one carbodiimide group whose first nitrogen and second nitrogen are bonded together by a bond group (component B). 3. The resin composition according to claim 1 , wherein Zand Zare each independently a single bond claim 1 , a double bond claim 1 , an atom claim 1 , an atom group or a polymer. This is a divisional of application Ser. No. 13/128,309 filed May 9, 2011, which is the National Stage of PCT/JP2009/071193 filed Dec. 15, 2009; the above noted prior applications are all hereby incorporated by reference.The present invention relates to a resin composition comprising a polyester and a cyclic carbodiimide.It has already been proposed to use a carbodiimide compound as an end-sealing agent for a polymer compound having a terminal acid group such as a carboxyl group so as to suppress the hydrolysis of the polymer compound (Patent Documents 1 and 2). The carbodiimide compound used in this proposal is a linear carbodiimide compound.When the linear carbodiimide compound is used as an end-sealing agent for a polymer compound, a compound having an isocyanate group is liberated by a reaction for bonding the linear carbodiimide compound to an end of a polyester to produce a smell peculiar to an isocyanate compound, thereby deteriorating work environment.Patent Document 3 discloses a macrocyclic carbodiimide compound. Since this compound is produced as a highly diluted solution, the concentration of the macrocyclic carbodiimide compound is low, whereby it takes many days to react it with a polymer and therefore the utility of the macrocyclic carbodiimide compound as an end-sealing agent for polymers is low. Further, Patent Document 3 does not take into consideration the reduction of an isocyanate smell produced by the end-sealing ...
