Title: Low-frequency audio enhancement system
Inventor: KLAYMAN ARNOLD I
IPC: H04S1/00
Filed: 1998-11-06
Granted: 2000-06-21
Abstract: The present invention provides an audio enhancement apparatus and method which spectrally shapes harmonics of the low-frequency information in a pair of audio signals so that when reproduced by a loudspeaker, a listener perceives the loudspeaker as having more acoustic bandwidth than is actually provided by the loudspeaker. The perception of extra bandwidth is particularly pronounced at low frequencies, especially frequencies at which the loudspeaker system produces less acoustic output energy. In one embodiment, the invention also shifts signal from one audio signal to the other audio signal in order to obtain more bandwidth for the available loudspeaker to reduce clipping. In one embodiment, the invention also provides a combined signal path for spectral shaping of the desired harmonics and a feedforward signal path for each pair of audio signals.

Title: Discharge mechanism for decomposition device of food processing residue
Inventor: FUJIMORI MASAHIRO
IPC: B01F7/02
Filed: 2000-06-29
Granted: 2002-02-21
Abstract: The present invention relates to a discharge mechanism for a decomposition device of food processing residue, particularly a discharge mechanism for a decomposition device of food processing residue which uses microorganisms to decompose and reduce the size to produce fertilizer or compost. In which, the interior of a mixing tank is installed with a mixing rod which is combined with the rotation shaft to form a mixing mechanism. A porous discharge hole is installed on one side of a location parallel to the rotation shaft. When the food processing residue is receiving a decomposition for size reduction, the content of the mixing tank will move on the opposite side of the side installed with the porous discharge hole due to the rotation of the mixing mechanism. After the residue decomposition and size reduction, the content of the organic compost will move towards the porous discharge hole due to the reverse rotation of the mixing mechanism, thereby separating and discharging the organic compost.
