Patent EP-0418862-A2 (EP)
Inventor: MIURA KATSUNORI
IPC: H03L7/10
Filed: 1990-09-19
Abstract: A frequency modulation circuit includes a PLL which comprises a VCO (1) and with a loop filter (4) which is operated by a current source. Such a frequency modulation circuit is formed in a monolithic IC. When a power source of the IC is turned-on, a capacitor (C1) included in the loop filter (4) is biased by an output voltage of a voltage follower (12) which receives Vcc/2. 
Since the output voltage of the voltage follower rises in the same manner as Vcc, a center frequency of the VCO (1) can be rapidly pulled-in in a phase-locked state of the PLL. In addition, the frequency modulation circuit is provided with a V-I conversion circuit which increases a charging current for the capacitor in response to a mute signal generated when the power source is turned-on, whereby a time constant of the loop filter is made substantially small.

Abstract: A technique of efficiently managing Write Once Read Mostly (WORM) volumes on mass optical storage devices is disclosed. A configuration menu asks the user to enter a threshold percentage from 1-100%. The threshold percent­age is multiplied by the volume size to determine a threshold block address. New files are written sequen­tially to the WORM volume up to but not exceeding the threshold block address (57), unless a threshold override indicator is enabled (59). Space on the WORM volume be­tween the threshold block address and the end of the WORM volume is reserved for updated files (60, 61, 62). Updat­ed files can be stored anywhere on the WORM volume, in­cluding above the threshold block address (63). Reserving space for updated files on a WORM volume allows more updated files to be stored on the same WORM volume as original files, and reduces the number of optical disks required to be read. The threshold percentage can be modified by the user at any time desired.

Abstract: In response to a data processor (10) breaking a wireless link with a first, original, link adapter (12) a first step deletes the data processor from an active group of the first link adapter and re-directs network datagrams intended for the data processor to a spooler. In response to the data processor subsequently establishing a link with a second, new, link adapter a next step adds the data processor to the active group associated with the second link adapter and transmits stored datagrams in a First In/First Out order from the spooler to the second link adapter for transmission to the data processor. In response to the storage device transmitting all of the stored datagrams to the second link adapter the method includes the further steps of terminating the re-direction of datagrams from the first link adapter to the storage device and, receiving, from the network with the second link adapter, further datagrams addressed to the data processor.

Abstract: In a speech recognition system for deciding an input pattern as one of a number of reference patterns, dissimilarities between the input pattern and the reference patterns are determined (28), and the minumum one of the dissimilarities is selected and is then compared with a reject value, to decide which particular reference pattern produces the minimum dissimilarity. In order to reduce the effect of noise accompanying an input speech pattern, the noise level (Z) is detected (22) from an input pattern before the input speech pattern is detected and the reject value is produced (25) in dependence upon the noise level. The minumum dissimilarity is normalised and the normalised value is compared (30) with the reject value (r(Z)).
