Abstract: A service architecture for Internet telephony that utilizes mobile agents and the Session Initiation Protocol (SIP). The architecture includes a mobile agent that includes service scripts for a plurality of related services such as all originating services or all terminating services. A service interaction manager in the mobile agent controls interactions between the related services.

A terminal equipped with an agency retrieves and executes the services. Adapters for each script language enable the agency to retrieve the service scripts from the mobile agent. Additionally, a general adapter controls general and service-paradigm-independent interaction between the mobile agent and basic call processing functions in the terminal. A Service Implementation Repository (SIR) contains executable code for all services to which end users can subscribe, and a Service Management Unit (SMU) creates and updates mobile agents according to the end user's subscription by downloading relevant elements from the SIR. The architecture supports intra-domain and inter-domain service mobility, and immediate and on-demand service provision.

Title: Process and catalyst/sorber for treating sulfur compound containing effluent
Inventor: CAMPBELL LARRY E
IPC: B01J23/56
Filed: 1999-06-16
Abstract: A process and composition are provided for removing contaminants, such as sulfur dioxide and hydrogen sulfide, out of exhaust gases by contacting the contaminated exhaust gas with a catalyst/sorber composition comprising noble metal components and a sorber component, such as oxides of Ti, Zr, Hf, Ce, Al, Si and mixtures thereof, so as to remove the contaminants out of the exhaust gas. The contaminant-loaded catalyst/sorber composition is regenerated via contact with a mixture of an inert gas, such as nitrogen, and a reducing gas, such as hydrocarbons. The catalyst/sorber composition may also contain a modifier, such as Cu, Ag or Bi, which tends to promote the release of the sulfur contaminant off the contaminant-loaded catalyst/sorber composition as sulfur dioxide, rather than the hydrogen sulfide.  The catalyst/sorber composition also promotes the oxidation of carbon monoxide in the exhaust gas.

Abstract: A power management method and system is used with mobile terminals and base stations of a wireless communications system. A conventional random access channel downlink that provides information on whether the channel is availab le for use by a new mobile terminal is enhanced. While a first mobile terminal is establishing a connection with and transmitting a message to a base station,  the base station repeatedly transmits a random access channel downlink that includes the number of units of time remaining in the current message transmission. A second mobile terminal wishing to establish communication wi th the base station receives and processes this information. Normally, the seco nd mobile terminal would continuously monitor the channel until an idle indication is detected. However, by knowing the number of units of time remaining for the current message transmission, the second mobile terminal c an conserve battery power by ceasing reception and processing of the downlinked  slots until the specified time has expired.

Abstract: An arc fault detector system (10) detects arcing faults in an electrical distribution system by monitoring one or more conductors (14) and producing an input signal representing one or more electrical signal conditions in the circuit (12) to be monitored. This input signal is processed to develop signals representing the electrical current flow through the monitored circuit (12) and broadband noise signal components. The system (10) analyzes these signals to determine whether an arcing fault is present, and if so, outputs a trip signal which may be used directly or indirectly to trip a circuit breaker or other circuit interruption device (44).
