Abstract: In a handwriting recognition system a method for differentiating a first character from a second character having similar characteristics. The method includes the steps of determining during a training session at least one pairwise discriminant measure associated with the first character and with the second character. The step of determining includes a step of evaluating with a potential discriminant measure a plurality of prototype first characters and a plurality of prototype second characters. Subsequently, during a handwriting recognition session, the method evaluates with at least one of the previously determined discriminant measures selected from a set of same an input character identified as being either the first prototype character or the second prototype character. The step of evaluating includes a step of analyzing a stroke or strokes associated with the input character in accordance with one or more of the pairwise discriminant measures selected from the set, summing the results of each discriminant measure analysis to obtain a result for each of the pair of characters associated with the pairwise discriminate measure, and selecting a character from the pair that has a maximum value result.

Abstract: In a tap control circuit for use in an adaptive filter for filtering a received signal into a filtered signal in accordance with first through N-th controllable tap gains which are produced by a producing section dependent upon the filtered signal and a control parameter, where N represents a positive integer which is not less than one, a first generating section (51) is for generating a first parameter and a second generating section (52), for generating a second parameter which is greater than the first parameter. A selecting section (53-55, 57) selects one of the first and the second generating sections to selectively supply the first and the second parameters as the control parameter to the producing section in accordance with the first through the N-th controllable tap gains. Preferably, the tap control circuit comprises a controlling unit (43, 44, 46, 47, 56, 59) for controlling the producing section to select selected ones of the first through the N-th controllable tap gains in accordance with the first through the N-th controllable tap gains. As soon as the adaptive filter is put into operation, the selecting section selects the first generating section to supply the first parameter to the producing section. When the selecting section selects the second generating section to supply the second parameter to the producing section, the controlling unit is put into operation and selects the selected ones of the first through the N-th controllable tap gains.

Abstract: A musical tone generation apparatus is provided with a plurality of tone generation channels, a first memory for storing musical tone parameter including tone color specifying parameter, i.e. , tone color name or number of tone color, in units of the tone generation channels, and a second memory for storing tone color parameter data. When tone color change is designated, the first parameter memory outputs tone color specifying parameter to the second parameter memory. In response to this, the second memory outputs the changed tone color parameter data to the tone generation channels to thereby generate tone having new tone color. As a result, tone color change is easily performed.

Abstract: The air conditioning system has radiators (13) for the purpose of heating. For room cooling, an air-cooled cooling ceiling (14) is provided, the outlets of which are arranged, in the form of source air outlets (20), in direct proximity to the room walls (10). The overpressure in the cooling ceiling is so low that the cooling air descends along the room walls in a laminar flow under the effect of gravity. As a result, injection-free and turbulence-free wall cooling is created, so that not only the cooling ceiling but also the room walls absorb heat. Draughts are avoided. <IMAGE>

Abstract: Provided that, as is the case in the digital communication networks, in particular in the integrated data and telephone network (ISDN), the telephone number data of a calling subscriber are transmitted directly to the called terminal or the PBX system to which this terminal is connected, a comparison of this telephone number data with the entries in an internal or external database takes place. This database contains, at least for a specific number of external telephone subscribers, special information which identifies more precisely these relevant subscribers. This includes, for example, the name, date of birth, customer reference number and address details. If the transmitted telephone number is held in the database, at least a part of this special information is shown on the display of the terminal or is printed out with the aid of a printer. A special form of a database of this type uses the information which is stored centrally for so-called short-code dialling destinations on a PBX system. For these destinations which can be reached through simplified dialling, the names of the relevant external subscribers are stored along with the respective corresponding complete telephone number information. If the transmitted telephone number data correspond with one of the stored telephone number information elements, the allocated name is displayed. In this way, a name display can be implemented without the additional expense of a memory space for external subscribers, with whom frequent telephone contact normally takes place. <IMAGE>

Abstract: High-voltage circuit breaker of the self-blasting and/or puffer type, where the movable arcing contact (3) of the circuit breaker, at least during a considerable part of a breaking operation, is operated at a higher speed than the movable operating current contact (10), which is built together with the pressure storage chamber (7) and auxiliary puffer cylinder (14) of the breaker. A blast nozzle (5) arranged coaxially around the arcing contacts (2, 3) is supported by one of the movable contacts (3, 10). By means of a special link mechanism (31, 32), a speed ratio between the two contact systems may be obtained which is changed in an optimal manner with respect to dielectric strength and energy requirement during an opening operation. The communication between the arcing zone and the pressure storage chamber (7) takes place through a channel (6) arranged in the blast nozzle (5), the inlet position of the channel in the pressure storage chamber being displaceable during an opening operation. In this way, a gas mixing which is more favourable for the arc extinction is obtained in the pressure storage chamber (7).

Abstract: The invention is a system and method that uses a digital oscilloscope to digitize a waveform and then loads the digitized waveform into a computer. The computer scans the waveform data locating leading edges by comparing data to a rolling average and a noise threshold and locating tops bottoms if the pulse is negative going of pulses by comparing data to slope criteria until a trailing edge is discovered. The trailing edge defines the end of the pulse, the immediately preceding leading edge defines the beginning of the pulse and the pulse height and this allows the pulse characteristics to be determined. This discovered pulse is removed from the waveform by setting all data values in the pulse to the pulse baseline value, and the scan for leading edges, pulse tops and a trailing edge is performed again to isolate and characterize another pulse. This cycle of detection, analysis and removal continues until the end of data is encountered before a pulse is discovered.
