Title: Method and system for performing electronic money transactions
Inventor: NIKANDER PEKKA
IPC: G06Q20/00
Filed: 1997-12-12
Granted: 2006-02-07
Abstract: The present invention relates to electronic monetary systems in general, and in particular to measures for making their use easier for an average user. The present invention is based on the idea that the use of electronic money is greatly simplified for a non-expert user, if the Internet Service Provider of the user takes care of the payments, and adds corresponding charges on the user's telephone bill. Such functionality inquires the intervention of the ISP in the transmissions between a user and a third party, i.e. intercepting the electronic payment requests sent by a merchant. According to the present invention, the ISP uses electronic money on behalf of the user, and charges the payments on the user's telephone bill. The ISP can take care of all technical details necessary for obtaining different forms of electronic money in a centralized manner, and all users of the ISP can use the electronic money obtained by the ISP simply by allowing the ISP to add corresponding charges to their telephone bills. Further, the ISP can obtain all major forms of electronic money, whereafter a user can choose the most economical way of payment, if a merchant accepts payments in more than one form of electronic money.

Abstract: A dual section liquid-cooled panel (10) having a primary section (12) and a secondary or back-up section (14) adjacent to the primary section (12) lines a portion of the interior surface of a metallurgical furnace. A three-way valve controls the flow of fluid to the operating section (12, 14) of the panel (10). Initially, the primary section (12) is operational and the valve is set to permit the flow of fluid to the primary section (12). If the primary section (12) suffers structural damage, the valve can re-direct the cooling fluid to the secondary section (14). The secondary section (14) becomes operational until regular maintenance is scheduled for the furnace.

Abstract: Conventional telephone sets normally include a microphone housing defining an opening to the exterior which communicates with a cavity in the microphone housing within which is located an internal microphone, and leads connecting the internal microphone with a PCB. An improvement is proposed, namely the provision of an external microphone connected to a plug which is receivable snugly within the opening, thus to substantially block external sound from reaching the internal microphone. Contact devices link the PCB with portions of the plug and thus with the external microphone.

Abstract: A device measures pressures in animals and humans and includes a pressure transmission catheter (22) filled with a pressure transmitting medium (26) and implantable in an area having a physiological pressure. A transducer (30) communicates with the pressure transmitting medium (26) to provide a pressure signal representing variation s in the physiologic pressure on electrical wires (34). A connecting catheter (36) carries the electrical wires (34) to signal processing and telemetry circuitry (38), which transmits a telemetry signal representing the pressure signal to a receiver external to the animal or human. A housing (44) holds the signal processing and telemetry circuitry (38), but the transducer (30) is remote from the housing (44). The device performs measuring of venous pressure, pulmonary pressure, bladder pressure, or intracranial pressure without significant hea d pressure artifact and with a sufficient dynamic response. One embodiment of the catheter (22) includes a multi-durometer stem.

Abstract: A synchronization acquiring circuit for stably acquiring frame synchronization without pseudo-synchronization lock during reception at a low C/N ratio. The C/N ratio of a transmission path is determined by a C/N ratio determining circuit (9) and a correlation detection reference value is determined on the basis of the determined C/N ratio. The synchronization pattern of a received frame is detected by a frame synchronization detecting circuit (2). The bits of the synchronization pattern of the received frame are compared with those of a frame synchronization pattern on the transmission side by a frame synchronizing circuit (5) to determine the number of coincided bits. The frame synchronization is regarded as detected when the determined number of bits of each frame is equal to or larger than the correlation detection value. When a reception signal phase vector distribution determining circuit (8) detects that a distribution vector of signal point positioning of a TMCC interval is normal and a burst symbol signal error measuring/judging circuit (10) judges that the distribution vector of a burst symbol signal is normal, synchronization is regarded as established.

Title: Establishing connections with a pre-specified quality of service across a communications network
Inventor: GIBSON MARK
IPC: H04L12/24
Filed: 2000-06-29
Granted: 2010-05-11
Abstract: On receipt of a request for a communication session over a communications network, such as an Internet Protocol communications network, a method of establishing a path for this session which provides a guaranteed quality of service is described. In a preferred example the communications network is an MPLS network and the method uses a modified version of the SIP messaging protocol. A number of possible paths for the communication session are identified and ranked according to factors such as traffic levels. Bandwidth along a chosen path is reserved and a messaging protocol such as CR-LDP used to establish this reserved path for the communication session. An advertising mechanism is used to provide entities in the network with information about topology and traffic levels. This enables the ranks to be determined effectively. The communications network has an overlay network of high capacity paths established on it. By arranging for communication sessions to preferably be established using these predetermined high capacity paths the complexity of the topology information required is reduced.

Abstract: A method of producing optical waveguide gratings that includes a grating portion formation step for forming a grating portion in an optical waveguide having a core composed of a material with a refractive index that changes when exposed to UV light by irradiating the optical waveguide with a UV beam from a Uv light source. The UV beam's exposure time of the optical waveguide is varied along the longitudinal direction of the optical waveguide during the grating portion formation step by positioning a shielding plate between the optical waveguide and the W light source and moving the shielding plate while irradiating with the UV beam.

Title: Improvements in and relating to liquid dispensing apparatus
Inventor: BOLTON TERENCE WILLIAM
IPC: B43K8/02
Filed: 1999-05-12
Granted: 2009-04-28
Abstract: Liquid dispensing apparatus comprises a tubular casing having at one of its ends a mouthpiece and an elongate cap, and at the other of its ends a nozzle having an orifice in communication with an expansion chamber bounded by sides which diverge away from the orifice. A  liquid source including an elongate body and an absorbent nib (e.g. a felt-tipped pen) is located within the casing with side surfaces of the pen body spaced from internal wall surfaces of the casing to define an air flow passageway therebetween. First and second stop means are provided within the casing against the first of which a surface of the elongate body can abut to position the nib of the liquid source within or in close proximity to the nozzle orifice, and against the second of which a rearward end of the elongate body can abut to position the nib of the liquid source in a relatively airtight manner into one end of the elongate cap. The other end of the elongate cap is closed.  Thus the liquid source can selectively be positioned with its nib within or in close proximity to the casing nozzle or with its nib effectively sealed within the elongate cap when the apparatus is not in use.
