Title: Power source capacitance reduction system
Inventor: NAKAMURA MITSUYUKI
IPC: H02J3/00
Filed: 1991-05-10
Abstract: PURPOSE:To make the rated capacitance of the power unit small by suppressing the increase of the output current of the power unit, controlling the reception of a new call when the output current exceeds the prescribed value. CONSTITUTION:A current monitoring circuit 11 monitors whether the current flowing from a power unit 10 to a power feeding path 16 exceeds a certain reference value or not. When the current exceeds the reference value, it is notified to a central control device 12 by a data bus 18. The central control device 12 instructs the unusing circuit of a subscriber's circuit 13, trunk circuit 14 and various kinds circuit 15 to prevent the reception of a new call to prevent from increasing the power consumption more. In this case, if the unusing circuit is the subscriber's circuit 13, for instance, the power feeding circuit to the telephone machine is turned off. Even if the subscriber performs the off-hook it is all right to stop the flowing out of the current. The central control device 12 suppresses the increase of the consumption power current by rejecting or deferring the capture request of the trunk circuit, etc., from the outside by the common line, etc., if the request exists.

IPC: G10L15/04
Filed: 1989-04-24
Abstract: PURPOSE:To enable stable sound section detection even when a sound section present in a noise section having time variation is detected by selecting only a feature quantity component having small time variation as the feature quantity of the noise section and updating it at a proper period. CONSTITUTION:Plural feature quantities of a noise signal are analyzed 4 statistically and only a constant number of feature quantities having small time variation are selected 6 and registered 5 as feature quantities representing the noise. Then the statistical deviation value between the registered feature quantities and the feature quantities of an input signal is compared 9 with a preset threshold value. When the noise is decided, feature quantities of a next input signal are stored 3, a statistical analysis 4 is taken when a constant number of feature quantities are stored, and feature quantities of the noise signal are selected 6 and registered 5 to update the feature quantities in the noise section. Then a next signal is received and when a sound is decided, sound section detection 11 is performed by using the relation between the large/small state of the statistical deviation value and the continuance of the section. Consequently, the sound section is estimated stably against the time variation of the noise section.
