Patent EP-0444351-A2 (EP)
Inventor: FLANAGAN JAMES LOTON
IPC: G06F21/20
Filed: 1990-12-14
Abstract: A voice password-controlled security system is disclosed. After the normal password procedure is successfully completed, the computer (12) institutes a voice call to a telephone (13) associated with the user. The computer queries the user to repeat a randomly selected series of digits or a phrase consisting of a group of words. The computer then compares the voice information received over the voice line with pre-stored voice information associated with the purported user. The computer affords access to its resources if and only if a voice match occurs. Due to the high reliability of the voice recognition system, intruders, even those with password information and who mimic the user's voice, will usually be precluded access to the computer. Significantly, the system is effective yet places no additional burdens on the user, such as memorizing additional codes or carrying encryption devices.

Abstract: A two-stage final drive selectively provides two gear ratios between a transmission output member (18) and the final drive or differential in a vehicle driveline. The two-stage final drive utilizes a planetary gear arrangement (32) having a plurality of stepped pinion gears (34) meshing with an input sun gear (26) and two selectively brakable ring gears (28,30). The planet carrier (32) is connected with the input to a differential gear arrangement (14). The stepped pinion planetary gear arrangement provides two underdrive ratios and has operatively connected to one of the reacting ring gears, a dual mode roller brake (52) which is selectively controlled to provide a path to ground in two directions when the transmission is conditioned for Park, Reverse or Neutral, and a path to ground in one direction during the operation of the transmission in the forward direction. The dual mode device will permit forward rotation of the low speed ring gear (28) when the high speed ring gear (30) is selected as the reaction member. The dual mode member permits a conventional parking brake arrangement to be utilized by the transmission. As an alternative to the dual mode device, a more conventional one-way device in combination with a selectively operable mechanical one-way brake arrangement can be utilized in the two-stage final drive.

Abstract: A semiconductor body (1) is provided having a first region (4) of one conductivity type adjacent one major surface (2). An insulating layer (5) is formed on the one major surface and masking means (6,7) are used to form over first and second areas (20 and 21) of the one major surface (2) windows (8,9,10) in the insulating layer (5) through which impurities are introduced to form a relatively highly doped region (11) of the opposite conductivity type adjacent the first area (20) and a relatively lowly doped region (12) of the opposite conductivity type adjacent the second area (21). The surface (5a) of the insulating layer (5) is exposed prior to introducing impurities of the one conductivity type for forming a region (13) within the relatively lowly doped region (12) of the opposite conductivity type and with a dose sufficient to form the region (13) but not sufficient to overdope the relatively highly doped region (11) so avoiding the need to mask the first area (20) during this step. The thickness of the insulating layer (5) is such that a proportion of the impurities of the one conductivity type penetrate the insulating layer (5) to increase the doping of a surface layer (40) of the first region (4) so as to reduce problems such as punch-through effects.

Abstract: A selection unit (5), which is provided between an input matching unit (2) and a high frequency amplification unit (1), is used to select a specific high frequency band to be amplified by the high frequency amplification unit (1) from high frequency signals input from an input terminal (D IN ). Further, an attenuation unit (6), which is provided between an input of the high frequency amplification unit (1) and ground (GND), is used to attenuate the input high frequency signals except for the specific high frequency band. Therefore, the specific high frequency band of the input high frequency signals is transferred from the input terminal (D IN ) to the high frequency amplification unit (1) through the selection unit (5) with a small loss, and the input high frequency signals except for the specific high frequency band are attenuated by the attenuation unit (6). Further, not only can a stability of the high frequency amplification unit (1) in the specific high frequency band used for the amplifier be realized, but stability of the high frequency amplification unit (1) in other frequency bands except for the specific high frequency band can be also realized. Consequently, the high frequency amplifier does not oscillate and is not damaged.

Abstract: The synthesis of 2,3-dihydro-1H-pyrrolo[1,2-a] benzimidazole-5,8-diones (azamitosenes) (I) was carried out in conjunction with the design of potential DNA crosslinkers activated by reduction (reductive alkylation). These quinones resemble mitosene antitumor agents, but are based on the benzimidazole nucleus rather than the indole nucleus. Preliminary results indicate the azamitosenes are potent antitumor agents. Iminoquinone derivatives of azamitosenes (iminoazamitosenes) (II) were synthesized as reductive alkylating agents exhibiting low oxygen toxicity. The iminoazamitosenes are hydrolytically stable in neutral buffers and undergo buffer catalyzed syn/anti isomerization at the imino center. Electrochemical and oxygen reactivity studies in aqueous buffers indicate the change from quinone to iminoquinone is accompanied by an increase in reduction potential and a decrease in oxygen reactivity of the corresponding reduced species.

Abstract: The invention relates to a method and apparatuses for thermal wave analysis, which is applied to measure geometrical, thermal, electronic and elastomechanical material parameters of solids, in particular of their surface layers. It is chiefly applied in coating technology. 
<??>The object of reducing the technical complexity and sensitivity limit of thermal wave analysis is achieved according to the invention when a single laser beam which has an additive two-frequency intensity modulation is directed onto the object and the amplitude of the mixed frequency of the discrete modulation frequencies that is not contained in the excitation beam is analysed as the response signal. An advantageous suppression of noise and reduction in the sensitivity limit are achieved through obtaining a reference signal from the excitation beam and forming its difference with the measured signal.

Abstract: In mobile radio, the channel impulse response is time-variable due to the Doppler effect. The problem is to estimate these changes in a receiver and to take account of them. A novel method for estimating the time variation of the channel impulse response is represented here. The novel method is suitable, for example, for TDMA systems such as the GSM system. With a continuous transmission (FDMA), the method can also be used if bit sequences known to the receiver (training sequence) are occasionally transmitted. The method operates independently of the correlation characteristics of the symbol sequences transmitted.

Abstract: A data processing system method and program are disclosed for limiting a book reading program for softcopy books, to be capable of reading only softcopy books published by a selected publisher. The method includes the step of generating with a data processor, a customized polynomial expression to be associated with a selected softcopy book publisher. The method continues by merging with a data processor, the customized polynomial expression with a first shell program, forming a stamping tool program for stamping a key value onto a softcopy book published by the selected publisher. The key value results from the polynomial, using the product of an integer times a hash value of the publisher's identity, as the value of the independent variable. Then the method continues by generating with a data processor, a customized inverse polynomial expression to the customized polynomial expression, to be associated with the selected softcopy book publisher. Finally, the method merges with a data processor, the customized inverse polynomial expression with a second shell program, forming a book validation program for validating the key value on the softcopy book published by the selected publisher and enabling a softcopy book reading program to read the softcopy book. If the key value read from the book by the validation program, is determined to be an integral multiple of the publisher's hash value, then the key is valid.

Abstract: A toner quantity detecting system has a toner quantity detector (4c) and is capable of accurately detecting the decrease of the quantity of toner contained in the toner container of the developing unit of an image recording apparatus to an upper threshold quantity and to a lower threshold quantity regardless of the inherent output characteristic of the toner quantity detector (4c) and determining a prewarning voltage (E nep ) representing the upper threshold quantity and a warning voltage (E emp ) representing the lower threshold quantity so that the difference between the prewarning voltage (E nep ) and the warning voltage (E emp ) is sufficiently large. The prewarning voltage (E neP ) and the warning voltage (E emP ) are determined on the basis of the inherent output characteristic of the toner quantity detector (4c). The output voltage (E s ) of the toner quantity detector (4c) is compared with the prewarning voltage (E nep ) and the warning voltage (E emp ) to provide a prewarning signal (NAL) upon the reduction of the quantity of the toner to the upper threshold quantity and to provide a warning signal (EAL) upon the reduction of the quantity the toner to the lower threshold quantity.
