Title: Multi-channel audio enhancement system for use in recording and playback and methods for providing same
Inventor: KLAYMAN ARNOLD
IPC: H04S3/00
Filed: 1997-11-05
Granted: 2000-07-01
Abstract: An audio enhancement system receives a group of multi-channel audio signals and provides a simulated surround sound environment through playback of only two output signals. The multi-channel audio signals is composed of a pair of front signals, which are intended for playback from a forward sound stage, and a pair of rear signals, which are intended for playback from a rear sound stage. By separating an ambient component of each signal pair from a direct component and processing at least some of the components with a head-related transfer function, the front and rear signals are modified in pairs. The individual audio signal components is determined by an intended playback position of the corresponding original audio signals. The individual audio signal components are selectively combined with the original audio signals to form two enhanced output signals for generating a surround sound experience upon playback.

Filed: 1999-01-27
Granted: 2002-01-01
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.
