Abstract: The present invention provides a heart murmur detection device. The heart murmur detection device includes: an ECG signal detection unit for detecting an ECG signal from a heart of a user; a heart beat detection unit for detecting the frequency of the ECG signal; a plurality of sound receiving units for receiving a plurality of sound signals from the heart of the user; a signal transforming unit for transforming the sound signals into a plurality of electric phonic signals, and for retrieving the electric phonic signals on the basis of the ECG signal; and a signal processing unit for determining a heart murmur generating position. Moreover, the present invention further provides a heart murmur detection method.

Abstract: The present invention concerns a scent-bearing and multimedia card or disk for use in conjunction with scent recovery and multimedia playback systems. The scent-bearing and multimedia card or disk comprises an encapsulated optical storage disk for storing multimedia information, and an associated scent storage medium for storing at least one scent. The scent-bearing and multimedia card or disk contains digital scent recovery and multimedia playback control information for use by an associated scent recovery/release and multimedia playback system. The digital scent recovery and multimedia control information is used by the multimedia playback and scent release system to coordinate multimedia playback and scent release. Additional embodiments of the present invention comprise electrostatic scent release systems and methods for effectively and efficiently releasing scent stored in the scent- and multimedia-bearing card or disk.
