IPC: G10K11/178
Filed: 1994-05-24
Abstract: PURPOSE:To obtain a muffling device trying a muffling corresponding to an objective noise by generating the noise signal from a noise source and a residual noise signal and generating and emitting an additional sound becoming the phase opposite to noise. CONSTITUTION:The quantitative discrimination of correlation is performed with respect to an acoustic signal or an electric signal inputted at a noise input part 1 by an input signal discriminating circuit 20 and the larger signal of correlation is selected by a detection changeover circuit 18 to be inputted to a signal processing part 3 via an amplifier 4 and a low-pass filter 7. Further, a residual noise input part 2 sends a detected signal to the signal processing part 3 via an amplifier 5 and the low-pass filter 7. The signal processing part 3 generates an additional sound signal so that the sound pressure in the peripheral part of a control point becomes minimum by performing a convolutional operation from these inputs. That is, the signal processing part 3 generates the additional sound signal for emitting the additional sound becoming the phase opposite to a noise signal based on the noise signal and a residual noise signal. This additional sound passes through a low-pass filter 8 and an amplifier 6 and then converted into an acoustic signal to be outputted as an additional sound by a control speaker 15.

Inventor: BOSSEN DOUGLAS CRAIG
IPC: G06F13/00
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To prevent damage due to a bus error in loading operation or storing operation through the identification of a device which encountered an error before by using forcible illegal data parity or 0-byte enabling. SOLUTION: Device select lines from respective I/O devices 132 and 134 are connected individually to a PCT host bridge 124 and if an error occurs on a PCI(peripheral component interconnect) bus, the device number of the faulty device is recorded in an error register 204. Following loading operation and storing operation are suspended until the error register is reset and until the device number of the object device is checked in the error register. If the object device got out of order before, the completion of the loading/storing operation on the device is stopped by forcing the illegal parity or setting all of byte enabling to zero. The I/O devices activate their device select lines when the illegal parity of 0-byte enabling is forced to answer a load request or store request, but accept no store data.
