Title: Speaker recognition device
Inventor: HATTORI HIROAKI
IPC: G10L17/10
Filed: 1998-01-27
Granted: 2001-11-27
Abstract: A speaker recognition device for judging whether or not an unknown speaker is an authentic registered speaker himself/herself executes 'text verification using speaker independent speech recognition and 'speaker verification by comparison with a reference pattern of a password of a registered speaker'. A presentation section instructs the unknown speaker to input an ID and utter a specified text designated by a text generation section and a password. The 'text verification' of the specified text is executed by a text verification section, and the 'speaker verification' of the password is executed by a similarity calculation section.      A judgment section judges that the unknown speaker is the authentic registered speaker himself/herself if both the results of the 'text verification' and the 'speaker verification' are affirmative. According to the device, the 'text verification' is executed using a set of speaker independent reference patterns, and the 'speaker verification' is executed using speaker reference patterns of passwords of registered speakers, thus considerably reducing storage capacity required for storing reference patterns for verification. Preferably, 'speaker identity verifi-cation' between the specified text and the password is executed.

Abstract: The invention relates to an administratively optimized calculation of communication bills process and/or system which, with the aid of a flat-rate-calculating computer (1), which is connected to an associated exchange (3) for customer terminals (7), carries out automatic administratively optimized calculation of communication bills. Such automatic administratively optimized calculation of communication bills is both for digitized and also for analogue communication networks, wire-bound, radio-based or laser-assisted, terrestrial or via satellite. Each terminal (7) is connected to a communication meter (8) which is lead-sealed or in other manner protected against manipulation and can be read by means of telemetry or, after the sending of a special meter-reading card, by the customer. The flat-rate-calculating computer (1) processes the information about consumed volumes of information in three ways. First, it compares the current values with the specified process widths and, if process alarm limits have been exceeded, generates a process alarm; it checks the current consumption values for the formation of a possible trend and generates an indicator alarm if there is a trend-wise exceeding of a limit value. It store: the charge information, process behaviour and alarms in a system memory (14) for documentation purposes. At a predetermined time or if there is a special need, it calculates a new flat-rate value which corresponds to the changed communication behaviour of the respective customer or group of customers. For the purpose of control, the flat-rate-calculating computer (1) is connected to an operator terminal (10) with hardcopy printer (11).

IPC: A62C31/12
Filed: 1999-07-19
Granted: 2008-10-14
Abstract: The foam based product solution delivery apparatus is simple in structure and operation and makes use of pressurized gas to power a pressure operated pump to draw the water/foam-concentrate/product(s) from supply tank(s) and propel the resultant solution (foam fluid), with pressurized gas injected therein, through an agitation apparatus that mechanically agitates the water/foam/product(s) solution to create the foam based product solution for transmission to the foam delivery apparatus. Interposed in the delivery apparatus between the pump and the outlet end of the hose, the agitation apparatus functions to significantly increase the foam expansion prior to delivery of the foam through the delivery apparatus. The agitation apparatus comprises an exterior housing inside of which is mounted a set of motionless mixing blades that function to mix and expand the foam. The agitation apparatus not only produces a high expansion of the foam but it also produces a more consistent bubble structure which enhances both the longevity and adhesion of the foam when applied to a structure.
