Title: Wavelength selective resonant gratings
Inventor: CHEN JERRY CHIA-YUNG
IPC: G02F1/313
Filed: 1999-10-20
Abstract: A wavelength selective resonant grating exhibits transmission resonances when a single gap between two sections of a split gratings is used to provide a phase shift which is not a quarter wavelength in length or .pi./2 in phase. When the phase is changed to non -.pi./2 values (or the gap differs from a quarter wave), the transmission resonance moves from the center of the stop band. Appropriate adjustments of the phase over a .pi. interval allow tuning of the resonance across the entire stop band. The resonant optical wavelength grating can, illustratively, be used as wavelength filter, wavelength monitor, or as part of an Add/Drop arrangement.

Abstract: This invention relates to distributing greeting cards. This invention also relates to disseminating advertising and promoting a company using greeting cards. The method comprises obtaining a sponsor.     The sponsor would typically pay an amount to cover some or all of the cost associated with the production, distribution, and display of a greeting card.     In exchange for the sponsorship, a sponsor message selected by the sponsor is placed on the greeting card, or alternatively, on a display stand for the greeting cards, or both. The sponsor message can include an advertisement, a company name of the sponsor, its trademarks, or a corporate image to be conveyed, or combinations of these. The greeting cards are then displayed on a stand, and usually in a manner and location that allows many people to view and browse the selection of greeting cards on display. Existing display stands that typically allow casual inspection of a variety of greeting cards can be used with this invention. Once a person has selected a greeting card that they wish to acquire, that person is compensated, typically in the form of conferring a benefit on the selecting person who acquires the greeting card.      The benefit can be the enablement of the selecting person to acquire the greeting card at less than a usual cost for similar greeting cards not including a sponsor message. This reduction in cost incurred by the selecting person is related to the amount that the sponsor pays towards the costs associated with the production and distribution of the greeting card. Typically, the benefit is the enablement of the selecting person to obtain the selected greeting card at no cost. The benefit could also comprise making a donation to a charitable organization.

Title: Telecommunications system
Inventor: DUTNALL STEPHEN
IPC: H04M3/00
Filed: 1998-08-14
Abstract: A system is disclosed for carrying packetised voice and other delay-intolerant traffic, for example a voice call for transmission over the "Internet", over a circuit-switched connection when such a connection is available. Incoming packets from a packet data network (52) are identified by a gateway node (60) as having voice characteristics and diverted to travel over a bridge (61) to a circuit-switched network (28, 24, 23) to a terminal (21), instead of a packet network (50). This reduces the load on the packet network (50), which is less suited to voice-type calls than is the circuit-switched network. In the reverse direction, suitable packets generated by the terminal (21) may be routed to the gateway node (60) by way of the circuit-switched network (24, 28) under the control of the terminal (21) itself, or under the control of the network's interface (23) with the terminal, either under the control of the gateway node (60) or autonomously.

Abstract: The invention is related to a method for forming calcium carbonate. In the method, calcium oxide is reacted with carbonate ions in the presence of water to produce calcium carbonate. According to the invention, the formation is carried out directly from calcium oxide to calcium carbonate without intermediate stages in a three-phase precipitation, whereby the hydration of the calcium oxide to calcium hydroxide and the carbonation of the hydrated part are carried out immediately after one another under so intensive agitation that the calcium carbonate elements thus created are detached from the surface of the calcium hydroxide. The mixing is preferably carried out in a fluid medium where the amount of gases phase is at least 20 parts by volume and the amount of liquid phase is 0.5 to 1 part per one part by volume of the solid matter of the suspension. In the process, the desired end product, PCC, can be prepared in a very short residence time and with a small operational content.

Title: Method, devices and signals for multiplexing payload data for transport in a data network
Inventor: GIESE PETER A
IPC: H04L29/06
Filed: 2000-05-19
Abstract: Data network signals, methods and devices that are suitable for multiplexing payload data in a packet switched data network are disclosed. Payload associated with multiple packets is multiplexed into a single multiplexed packet. Each payload portion is identified by a mini-header within the multiplexed packet. Mapping information may also be transferred as part of such multiplexed packets which include multiplexed payload data. Preferably, the mapping information is used to form mapping tables within routers at edges of access networks. The mapping tables may be used to establish a relationship between mini-headers and full headers. The mapping tables may be used to multiplex data from packets to form a multiplexed packet at an ingress router, and demultiplex the multiplexed packet at an egress router.      Conveniently, neither gateways nor out of band signalling are required.
