Title: Inline skate with one-way wheel
Inventor: CHANG YEN-NIEN
IPC: A63C17/22
Filed: 2004-12-08
Abstract: An inline skate has a number of wheels 3 at least one of which 31 is a raised wheel that is able to roll in only one direction, either forwards or backwards. The one-way rolling mechanism may comprise a one-way bearing (fig. 3), a one-way ratchet mechanism (fig. 4), or a one-way clutch (fig. 2). The raised wheel 31 may be a front wheel which is able to roll only in a forward direction, or may be a rear wheel 31 which is able to roll only in a backwards direction. The skate may have a front, forward rolling wheel and a rear, backward rolling wheel (fig. 8), and the one-way wheel or wheels may be smaller than the normal wheels. The one-way wheel or wheels may have a rugged or granular surface to increase friction. The rear one-way wheel may act as a brake when the skate is travelling forwards, with the front one-way wheel acting as a brake when the skate is travelling backwards. The front one-way wheel may also act as a ground kicking point which assists the user in propelling forwards.

Title: Distributed message transmission system and method
Inventor: WOOD IAN
IPC: H04W88/18
Filed: 2002-05-03
Abstract: Systems and methods for transferring at least one message, such as an SMS message, between components in a telecommunications network, such as a mobile telecommunications network is described. The message is received from a first component in the telecommunications network and the message payload is parsed to determine destination information for the message. The message is then routed to a second component in the telecommunications network based on the destination information determined, wherein the message is transferred between the components in the telecommunications network without passing through a Short Message Service Centre (SMSC) of the telecommunications network, wherein the at least one message is routed to the second component via a selected one of a plurality of message delivery components and wherein the message delivery component is selected based on the availability of the message delivery component. This may reduce the load on the SMSC of the telecommunications network and allow selective routing of the message to avoid congested components of the network.

Title: Compensation for heterogeneous nitrogen concentration in a nitrided silicon oxide layer
Inventor: WIECZOREK KARSTEN
IPC: H01L21/28
Filed: 2003-12-22
Abstract: The present invention provides a technique for forming extremely thin insulation layers requiring the incorporation of specified amounts of nitrogen, wherein the effect of nitrogen variations across the substrate surface may be reduced in that during and/or after the nitrogen incorporation an oxidation process is performed. The nitrogen variations lead to a nitrogen concentration dependent oxidation rate and, hence, a nitrogen concentration dependent thickness variation of the insulating layer In particular, the threshold variations of transistors including the thin insulating layer as a gate insulation layer may effectively be reduced.

Title: Method for the transmission of additional information in a communication system,exchange device and user station
Inventor: BACHENBERG MICHAEL
IPC: G06Q30/02
Filed: 2004-07-24
Abstract: The invention relates to a method for the transmission of additional information in a communication system (10), whereby a communication context connection (15a, 15b) is established from a first user station (11) to at least one second user station (12), for the transmission of information and/or data. Additional information is thus transmitted from an additional information device (14) to the second user station (12). The transmission occurs in a signal for the establishment of the communication context in a defined format, in order to permit a representation as electronic data card or ID card with text, image or multimedia content before the call reception. The transmission occurs, for example, depending on a release of the first user station (11) for the receipt of additional information. Query data are sent, for example, before the transmission. A selection can be carried out by means of a pre-selection or an additional code.

Title: Capturing and analysing TRIP packets in a peered, listen-only location server
Inventor: POLLOCK GRAHAM S
IPC: H04L12/56
Filed: 2006-04-10
Abstract: Information required for routing between IP Telephony Administration Domains (ITADs) 11,14 is gathered automatically by a location server 17 which operates in the listen-only, uni-directional, mode and which is peered with a Telephony Routing over IP (TRIP) inter-domain protocol. The peered location server uses the TRIP protocol to discover routing information thereby allowing for the automatic updating of route data for both internal and external telephony routes. In one embodiment, the peered router maintains an up-to-date picture of the service provider's routing and time stamps the collected data, thereby allowing for the collection and utilisation of historical TRIP performance information. Based on such historical analysis, the service provider can keep track of, for example, its most reliable peers, peering routes, unstable routes, unavailable routes etc.
