Title: Technique for notifying eigrp neighbors when destroying adjacencies in a computer network
Inventor: VAN TRAN THUAN
IPC: H04L12/56
Filed: 2004-02-17
Granted: 2009-12-15
Abstract: A technique efficiently notifies EIGRP neighbors when destroying adjacencies in a computer network. A goodbye notification packet is provided that enables an EIGRP router to inform one or more of its neighbors of its intention to destroy their existing adjacencies. The goodbye notification packet comprises an EIGRP packet header with variable-length fields embodied as an appended goodbye attribute. The appended goodbye attribute is illustratively tagged according to a TLV encoding format that defines a new type (T) field called "a goodbye" having a predetermined type that distinguishes it from a conventional EIGRP Hello packet. A value (V) field of infor~mation conveyed within the goodbye attribute contains a list of neighbor (peer) identi~fiers (IDs). The peer IDs on this list instruct those neighbor routers to "go away" so that their adjacencies can be destroyed.

Abstract: In order to fix the position of telescoping tubes of staffs or poles used in sports, especially ski poles, there is a clamping device (1) within the tubes (3,5). The clamping device (1) has a clamping part (21) and expansion bodies (17,19) which are assigned to the two ends of the clamping part (21). The expansion bodies (17,19) are screwed onto a threaded rod (11) with opposing threaded sections (13,15). By relative turning of the tubes (3,5) toward one another the expansion bodies (17,19) penetrate into the clamping part (21) from the two ends when the direction of rotation is selected accordingly and essentially uniformly widen it radially over its entire length so that it adjoins the inner surface of the outer tube (5) with a frictional connection and thus fixes the length of the pole once it has been set. In this way the tubes (3,5) can be fixed to one another in the desired relative position to one another with lower expenditure of force than in the past.

Granted: 2011-11-01
Abstract: A control method and system for a controllable pitch marine propeller including operating modes comprised of a manoeuvering mode and a cruise mode and check modes comprised of an engine check mode and propeller check mode.  The cruise mode provides for wide open throttle acceleration and power stop.  Smooth transition sub-modes are provided for providing smooth transition between cruise mode and manoeuvering mode and vice versa. The system operates by a lever (28) which controls a pitch control unit (10) which in turn controls engine speed and also the pitch of propeller blades (12) of propeller (14). Thus, dependent on the position of the control lever (28) in either manoeuvering mode or cruise mode, an appropriate engine speed and propeller pitch is selected automatically for driving a watercraft.

Granted: 2012-06-05
Abstract: An apparatus for cleansing and applying therapy or prophylaxis to wounds, in which irrigant fluid containing a physiologically active material from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. A biodegradable scaffold underlies the dressing on the wound bed to promote tissue growth. The cleansing means (which may be a single-phase, e.g. micro-filtration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed.

Abstract: A modified Family (11) xylanase enzyme comprising a sequence that introduces a functional consensus glycosylation site is provided. Non-limiting examples of introduced glycosylation sites include mutation of the amino acid at position (34, 131, 180, 182), or a combination thereof, to an asparagine. The indicated amino acid position in the Family (11) xylanase is determined from sequence alignment of the xylanase of interest with that of a Trichoderma reesei xylanase II amino acid sequence. The introduced consensus glycosylation site facilitates increased expression efficiency of the modified xylanase when compared to the expression efficiency of a corresponding xylanase from which the modified xylanase was derived, using similar host strains and growth conditions.

Granted: 2017-03-07
Abstract: The present invention relates to transaction processing, for processing of payments between payer's (usually individual payers) and payee's (usually merchants. Conventionally, a payment transaction involves a user's account details being provided to a merchant device, e.g. by swiping a card in the card swipe of the merchant device. The merchant device then prepares a transaction message including information such as the user's account ID, merchant ID and payment information and forwards that message to a transaction processing system, which may comprise a transaction acquirer and an issuing bank. The transaction processing system approves the payment and returns confirmation to the merchant. In the present invention a device associated with the payer, which in a preferred embodiment is a suitably adapted mobile telephone, becomes involved in the payment transaction process. At one level, the transaction processing system requests from the payer electronic device confirmation that the transaction should proceed and the payer keys in an appropriate PIN to authorise the transaction. At another level, all the transaction processing information is provided from the payer electronic device to the transaction processing system and the transaction processing system or the payer electronic device then confirm that the transaction is authorised to the merchant device. This takes the burden of transaction processing off the merchant and also increases the security of the transaction as the payer is in control. In a further embodiment, the payer electronic device may also upload listings of products and select products at the same time as paying for them, the payee (merchant) being advised of the selected product.
