Title: Signal processing system for achieving per-call control
Inventor: DEORA SANJEEV K
IPC: H04Q1/54
Filed: 1998-04-08
Abstract: A telecommunications network (10) includes an Originating Switching System (12 1) and a Terminating Switching System (12 2) linked by a plurality of trunks(20 1-20 4). For an incoming call it receives, the Originating Switching System establishes a Circuit Selection Capability Indicator (CSCI) that determines what enhancement, if any, the Originating Switching System will provide to the call. The Originating Switching System also utilizes the CSCI to select an appropriate trunk that is compatible with type of call enhancement, if any, to route the call to the Terminating Switching System which also enhances the call in accordance with the CSCI. The signal processing system per-call-control (SPCC) concept allows different types of calls which are routed on the same trunk to get different call quality enhancements (such as True VoiceR and Echo Control), depending on the call type. SPCC allows a call quality enhancement to be applied to an individual call on a per call basis, and these enhancements can be different at the OSS and TSS, which could give different types of enhancements to the calling party and called party. SPCC allows new signal processing "sound flavors", to be developed on the SPS, and these new sound flavors offered as a new service feature through CSCI Table updates in the switch, without software development. The SPCCconcept provides an evolutionary path for current overlay networks implemented for specialized signal processing requirements, in particular the dedicated TV off network for True VoiceR enhancement avoidance, and the dedicated EC off network to avoidecho cancellation for example for SDS services. The PCC capability of SPCC trunks allows the control of the TV Enhancement and the Echo Cancellation on a per call basis, thereby allowing the SPCC trunks to be used in a shared manner for calls requiring TV enhancement, calls requiring TV enhancement avoidance, and for data calls requiring no echo cancellation. The benefits are a) a very flexible per-call-control capability within a single integrated network, b) cost effectiveness, c) robustness to load surges, and d) improved network efficiency.

Patent CA-2254027-A1 (CA)
Inventor: LYONS ARTHUR P
IPC: B60L50/15
Filed: 1998-11-12
Abstract: An electric vehicle is controlled to conform its operation to that of a conventional internal-combustion-engine powered vehicle. In some embodiments, the charging of the batteries by the auxiliary source of electricity and from dynamic braking is ramped in magnitude when the batteries lie in a state of charge between partial charge and full charge, with the magnitude of the charging being related to the relative state of charge of the battery. The deficiency between traction motor demand and the energy available from the auxiliary electrical source is provided from the batteries in an amount which depends upon the state of the batteries, so that the full amount of the deficiency is provided when the batteries are near full charge, and little or no energy is provided by the batteries when they are near a discharged condition. At charge states of the batteries between near-full-charge and near-full-discharge, the batteries supply an amount of energy which depends monotonically upon the charge state. Charging of the batteries from the auxiliary source is reduced during dynamic braking when the batteries are near full charge. Control of the amount of energy returned during dynamic braking may be performed by control of the transducing efficiency of the traction motor operated as a generator.
