Title: Method and system for allowing a messaging system to determine how to process a call when a calling party's caller i.d. number is unidentified
Inventor: KAFRAY JOHN J
IPC: H04M1/57
Filed: 2000-12-19
Abstract: PURPOSE: A method and a system for processing non-labeled main calling in a message emission system are provided to efficiently process a phone call whose caller is not clear without taking much time. CONSTITUTION: When a system cannot confirm an ID of a caller of a phone call, the system requests the phone caller to enter a password in a DTMF(Dual Tone Multi-Frequencies). The system collates the entered password in this tone with a password programmed in the system. When the entered password is coincident with the password programmed in the system, the speech is processed depending on how the system is programmed to process the speech with respect to the password. There are a custom greeting (habitual greeting) method, a message limit method, and a screening on/off method or the like as possible processing methods. If the passwords are not coincident, the system rejects the acceptance of the speech.

Inventor: NAKAZAWA SHIGEYUKI
IPC: G11C7/10
Filed: 2000-12-27
Abstract: PURPOSE: To provide a semiconductor storage capable of shortening time from the start of one cycle and sense in a pre-charge control signal to both of initial reading or writing of it. CONSTITUTION: Input and output lines are pre-charged to voltage Va at a moment of time when a signal RASB is started. After that, when the pre-charge control signal PIO is started, potentials of the input and output lines are drawn by a potential of a bit line connected with a memory cell. Even when operation this time is reading of data from a selected memory cell, the voltage Va at a pre-charge level is higher than a balance level, so difference among the potentials of one bit line and the input and output lines become large and the potentials of the input and output lines largely drop. Next, when the pre-charge signal is started, the input and output lines are pre-charged to a voltage level Vb (balance level). Thus, even when operation before the pre-charge is writing, the potentials of the input and output line promptly reach the voltage Vb.

IPC: B60L7/10
Filed: 2000-12-28
Abstract: PURPOSE: A method for controlling regenerative braking of a hybrid electric vehicle is provided to control regenerative braking according to speed of an engine and velocity of the vehicle. CONSTITUTION: An electronic control unit discriminates whether or not to establish a predetermined condition of regenerative braking and detects a charging state of a battery, a vehicle velocity , and the number of an engine rotation when the regenerative braking is activated(ST21,ST24,ST25). The electronic control unit calculates amount of maximum regenerative braking according the charging state of the battery which is detected(ST26).

Patent KR-20010024051-A (KR)
IPC: G11B27/02
Filed: 1998-10-01
Abstract: Several audio signal processing techniques may be used in various combinations to improve the quality of audio represented by an information stream formed by splice editing two or more other information streams. The techniques are particularly useful in applications that bundle audio information with video information. In one technique, gain-control words conveyed with the audio information stream are used to interpolate playback sound levels across a splice. In another technique, special filterbanks or forms of TDAC transforms are used to suppress aliasing artifacts on either side of a splice. In yet another technique, special filterbanks or crossfade window functions are used to optimize the attenuation of spectral splatter created at a splice. In a further technique, audio sample rates are converted according to frame lengths and rates to allow audio information to be bundled with, for example, video information. In yet a further technique, audio blocks are dynamically aligned so that proper synchronization can be maintained across a splice. An example for 48 kHz audio with NTSC video is discussed.
