Title: Acoustic characteristics determination method for sound-conducting channel for exhaust fume tract of combustion engine
Inventor: FUESER ROLF
IPC: F02M35/12
Filed: 1997-11-25
Abstract: The method involves performing a first measuring process under operating conditions of the sound-conducting channel (1), and a further measuring process, whereby at least parts of the channel are set up in a separate measuring arrangement and predetermined sound oscillations are produced at one end of the channel. An evaluation is performed by determining the amplitude and the phase change of a series of basic oscillations and a selected amount of their harmonics. The method involves determining the actual sound conditions under operating conditions of the sound-conducting channel in a measuring process. The parts of the sound-conducting channel set up in the separate measuring arrangement for a further measuring process, and predetermined sound oscillations produced at one end of the channel, are evaluated at the other end in relationship to the input signal. The evaluation in the first and in the further measuring process is performed through determination of the amplitude and the phase change of a series of basic oscillations and a selected amount of their harmonics from one end of the channel to the other end. Correction elements are determined from the deviations from the first to the further measuring process, with regard to the amplitude- and phase changes of respectively equal frequencies.

Title: Method for operating magnetic resonance imaging equipment
Inventor: DEIMLING MICHAEL
IPC: G01R33/54
Filed: 1998-08-12
Abstract: The method involves delivering high-frequency excitation pulses (RF) to a patient with a repetition time, TR.
