Granted: 2000-09-05
Abstract: DGPS data obtained from an FM broadcast wave is extracted by a DGPS data extraction section (226).  Adjustment error, the accuracy of which is not very high, has been appended to correction data to be used in actual positioning correction within the obtained DGPS data.  A correction value creation section (228) judges, from the contents of DGPS data, which data in a correction value table (230) may be read.  The method of this judgment is predetermined.  Then, the correction value is created by reading the corresponding correction value from correction value table (230).  Next, the correction value and correction data are added in a DGPS data specifying section (232) to yield proper correction data.  Position information having high accuracy can be obtained from the obtained proper correction data.

Abstract: A layered architecture for a communication network comprises a first layer forming a transport network and a second layer forming a service network. The transport network provides bandwidth management, high capacity and physical layer survivability, and the service network provides switching and routing of the traffic, service layer survivability and other user oriented services. Combination of various technologies such as ATM, or IP over SONET/SDH are considered. A node of such layered networks comprises physically separated transport and service network elements (NE) interfaced to each-other.
Patent CA-2236447-C (CA)
Inventor: CASTLE RICHARD B
IPC: C03B19/10
Filed: 1996-10-31
Granted: 2007-07-03
Abstract: The disclosure describes methods for producing bulk, particulate material that includes solid, generally ellipsoidal particles. Irregularly shaped fee d particles with average particle sizes of up to 25 microns on a volume basis are dispersed in at least a portion of a combustible gas mixture by application of force and/or fluidizing agents. The combustible mixture with particles in suspension is then delivered, while controlling agglomeration or re-agglomeration of the particles, to at least one flame front. There, the mixture and suspended particles are uniformly distributed across the surface(s) of and passed through the flame front(s) with a high concentration of particles in the mixture. This flame front and the resultan t flame(s) with suspended particles are located in at least one "wall free" zone. In su ch zone(s) the flame(s) may expand while the particles are maintained in dispersion and heated, with controlled and highly efficient application of heating energy. At least partial fusion occurs within at least the surfaces of the particles at high thermal efficiencies, while agglomeration of particles during fusion is inhibited.

Granted: 2001-09-18
Abstract: An ultrasonic apparatus useable for welding metal by vibrations in the ultrasonic frequency range, employs a horn dimensioned to be resonant as a full wavelength resonator for vibrations of a predetermined frequency traveling longitudinally therethrough. To increase the energy available, the horn is coupled to a pair of transducers, one transducer coupled to each of the radially disposed end surfaces of the horn.          During operation, one transducer must be in its longitudinal expansion mode when the other transducer is in its longitudinal contraction mode and vice versa.  In order to accomplish this, two substantially identical transducers are used, but the orientation of the piezoelectric disc or discs in one of the transducers is reversed with respect to the orientation of the disc or discs in the other transducer.

Abstract: In a skills-based ACD, an agent is selected to handle a call based on which available agent's handling of the call will produce the least deviation from the agent's target performance criteria, and a call is selected for handling by an agent based on which available call's handling will produce the least deviation from the agent's target performance criteria. Illustrative target performance criteria include target per-agent per-skill skill work time to staff time ratios. Moreover, the selected call is left waiting and the selected agent is left idle if handling of the call by the agent would increase deviation from the agent's target performance criteria. This serves to equalize the levels of service given to small skills (those staffed with few agents) and large skills (those staffed with many agents).

Abstract: Uridine is a therapeutic agent active as a growth promoter for treatment of neuron degenerative diseases deriving from pathological ageing or selective destruction, in particular uridine shows the same biological effects of NGF, when added at low doses to the culture medium, so that uridine may replace NGF  as therapeutic agent in neural diseases and it may be also associated to other growth factors that allow neuron's differentiation, or with anti-cancer and anti-virus drugs that cause neuron damage. In addition uridine shows imporant trophic properties on various types of cultured cells, stimulating cell reproduction when used at rather high dose levels.

Granted: 2001-02-13
Abstract: A process to fracture connecting rods and the like, that are made of high strength materials, comprises of the following mechanisms: (a) Fatigue: fluctuation of stresses in a pre-notched connecting rod due to the use of harmonic excitation will extend the notch tip in the connecting rod and will weaken the predetermined fracture plane by creating micro-cracks. (b) Resonance: resonance occurs when the frequency of the used harmonic excitation matches a natural frequency of the connecting rod, idealized as a structural system. (c) Pre-stressing forces: by applying pre-stressing forces acting in the same loading mode, the stresses in the connecting rod due to several force components can be superimposed. (d) Dynamic force: applying a dynamic force will raise the stress intensity factor, exceeding the fracture toughness of the material.

Granted: 2006-02-07
Abstract: The system includes a computer adapted to conduct voice-over-data-protocol telephone calls, typically voice over Internet Protocol. Alternatively, the computer is adapted to conduct multi-media-over-data-protocol calls. The computer is connected to an on-line data service such as by a dial-up telephone connection. While on-line, a user at the computer is able to conduct telephone or multi-media calls with a voice-over-data-protocol or multi-media-over-data-protocol respectively. The user is able to place the call on hold, without disconnecting the call and perform other actions, such as performing on-line activities, or taking a second voice or multi-media call. The party placed on hold is informed of the hold action. The hold function is typically invoked by the computer and performed at a gateway, though hold at the computer and invoke by the non-computer party are alternatives. A set-top-box is considered a computer within the scope of the invention.
