Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04Q 7/20

US Classification:

4554351, 455433, 455440, 455443, 455453, 4554561, 455513, 370328, 370332

Abstract:

In a method of tracking a user in a communication network supporting a broadcast-multicast service, the network classifies groups of users into tracking areas. Movement of a user may be tracked as the user crosses a boundary between two tracking areas in the network. The method may enable a balance to be achieved between use of uplink overhead and the level or granularity of tracking desired, so as to conserve radio resources.

Filed:

Dec 30, 1981

Appl. No.:

6/336010

Inventors:

Michael J. Dolan - Laurel Springs NJ
Timothy L. Hilbert - Clementon NJ
John D. Snyder - Pittsburgh PA

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

G01N 3300

US Classification:

55 97

Abstract:

Method for measuring particulates in flue gas streams containing chemicals reactive with trace elements in the filters is disclosed which features pretreating the filters with chemicals comparable to those in the process stream whereby the reactions are completed prior to the measurement step, in particular, prior to establishment of the tare weight of said filter.

Filed:

Apr 9, 1982

Appl. No.:

6/366951

Inventors:

Michael J. Dolan - Laurel Springs NJ
Stephen J. McGovern - Deptford NJ
Peter J. Owens - West Deptford NJ

Assignee:

Mobil Oil Corporation - New York NY

International Classification:

C10G 1118
B01J 3714

US Classification:

208113

Abstract:

The concentration of sulfur trioxides in an FCC unit regenerator is maintained within environmentally accepted limits, while maintaining an adequate amount of gas for fluidizing conditions in the regenerator, by admixing the regenerator oxygen-containing gas with an inert gas. The quantity of the inert gas is controlled by a control loop measuring the pressure drop in the regenerator, and adjusting the amount of the inert gas to maintain the pressure drop within the predetermined limits.

Appl. No.:

8/198085

Inventors:

Michael G. Dolan - Orange CA

Assignee:

Celeritas Technologies, Ltd. - Irvine CA

International Classification:

H04B 138
H04L 2706

US Classification:

375222

Abstract:

A system and method for reducing amplitude distortion in data signals transmitted via cellular analog communication systems are embodied in several forms. In one embodiment, pre-emphasis and de-emphasis functions of the cellular system are offset by complementary de-emphasis and post-emphasis circuits to preclude clipping of high frequency components of the data signal by the limiter. Alternatively, the limiter circuit is selectively bypassed when a data signal is transmitted. Alternatively, a pilot tone is combined with the incoming data signal. The amplitude of the pilot tone is constant and always sets the gain of the limiter, thereby keeping the gain of the limiter circuit constant. Alternatively, a pair of signals at different frequencies are transmitted on a telephone line, and the relative amplitudes of the return echoes are measured to determine the frequency roll-off of the line and adjust the spectral shaping accordingly. Alternatively, a pair of modems vary their respective spectral characteristics until the eye quality values of the two modems are satisfactory.

US Classification:

208113

Abstract:

Sulfur trioxide concentration in the flue gas of catalytic cracking regenerators is maintained at a predetermined level by controlling the flow rate of oxygen-containing regeneration gas into the regenerator, and, optionally, the amount of carbon monoxide combustion promoter in the regenerator.

Appl. No.:

8/099080

Inventors:

Michael G. Dolan - Orange CA

Assignee:

Celeritas Technologies, Ltd. - Mission Viejo CA

International Classification:

H04Q 700

US Classification:

455 331

Abstract:

A system and method for reducing amplitude distortion in a data signal transmitted through a cellular analog communication system is embodied in several forms. Each specific embodiment of the invention eliminates distortion caused by clipping or sluggish recovery time induced by a limiter circuit which exists in conventional cellular communication systems. In one embodiment, pre-emphasis and de-emphasis functions of the cellular system are offset by complementary de-emphasis and post-emphasis circuits so that the high frequency components of the data signal are not clipped by the limiter. In another embodiment, the limiter circuit is bypassed selectively when a data signal is transmitted. In an alternative embodiment, a pilot tone is combined with the incoming data signal. The characteristics of the pilot tone are such that amplitude of the pilot tone is constant and always sets the gain of the limiter, thereby keeping the gain of the limiter circuit constant.
