Title: Wave field synthesis apparatus and method for driving an array of loudspeakers
Inventor: SPORER THOMAS
IPC: H04S3/00
Filed: 2004-05-28
Abstract: The invention relates to a wave field synthesis device for driving an array of loudspeakers with driver signals, whereby the loudspeakers are placed at different defined positions. A driver signal for a loudspeaker is based on an audio signal, which is assigned to a virtual source having a virtual position with regard to the loudspeaker array, and on the defined position of the loudspeaker. Relevant loudspeakers of the loudspeaker array are firstly determined based on the position of the virtual source, a predefined listener position, and on the defined positions of the loudspeakers so that artifacts caused by loudspeaker signals, which move opposite a direction of the virtual source to the predefined listener position, are reduced. A device (24) for feeding the driver signal components for the relevant loudspeakers for the virtual source to the relevant loudspeakers is connected downstream from a device (20) for calculating the driver signal components for the relevant loudspeakers and for a virtual source, whereby no driver signal components for the virtual source are fed to loudspeakers of the loudspeaker array that do not belong to the relevant loudspeakers. Artifacts in an area of the listener space are hereby suppressed due to the generation of a wave field so that only the useful wavefield is heard without artifacts in this area.

Inventor: BEUTLER ARTHUR J
IPC: A61N1/36
Filed: 2004-10-28
Abstract: A cardiac pacemaker includes a power transmitter which periodically transmits a pulse of a radio frequency signal to a vascular electrode-stent that is implanted in a vein or artery of an animal. The vascular electrode-stent employs energy from the radio frequency signal to charge a storage device which serves as an electrical power supply. The vascular electrode-stent also detects a cardiac signal emitted from the sinus node of the heart and responds thereto by applying a pulse of voltage from the storage device to a pair of electrodes implanted in the vascular system of the animal. Application of the voltage pulse to the electrodes stimulates contraction of the heart.
