Title: Method for instrument determination of a measured variable which changes with time
Inventor: PATZKE JUERGEN
IPC: G01N21/75
Filed: 1997-09-26
Abstract: The present invention relates to a method for instrument determination of measured variable L(t) which changes with time, the intention being to determine the maximum value of L(t) in a region with a linear reaction profile, and the time as well as the duration of the reaction time window being variable with the linear region and depending on the nature of the reaction and the reaction conditions. Specifically, the present invention relates to the determination of protein concentrations with the aid of light scatter, which is produced by specific antibodies, in homogeneous solutions. In particular, the invention relates to reactions which take place slowly and have a largely linear profile over a relatively long time, the rate of formation of antigen-antibody complexes in the linear section of the reaction (V MaxLin) being determined as the measured variable.

Filed: 1997-10-06
Abstract: Dans un système assurant la diffusion en simultané d'un signal modulé numériquement et d'un signal FM analogique dans la même bande de fréquences FM, le signal composite est reçu et appliqué à un récepteur FM ordinaire et à un récepteur numérique conformément à l'invention. Un filtre de Kalman étendu est utilisé dans le récepteur numérique pour estimer le signal FM analogique selon une version du signal FM rétabli provenant du récepteur FM, et une version discrète du signal composite dont le spectre a été traduit et qui se trouve sur une fréquence porteuse intermédiaire. Le signal FM estimé, sous forme discrète, est soustrait de la version discrète du signal composite. Le signal résultant, qui est une version estimée du signal modulé numérique, est démodulé afin de rétablir les données numériques transmises.

Patent CA-2236336-A1 (CA)
Inventor: BHULLAR GURPREET
IPC: G11C11/406
Filed: 1998-04-30
Abstract: A regulator circuit is provided for use with cell plate voltage generators of memory cell capacitors and precharge bit lines voltage generators in semiconductor memories. The circuit employs a current source coupled to the charging reference voltage whose output is controlled by a level detector, which receives as input a reference level signal and the cell plate voltage. When the cell plate voltage drops below the reference level, the level detector triggers the current source, thereby recovering the cell plate voltage to the reference level. The level detector can be disabled through an input to reduce current consumption after a fast power up has been achieved.

Title: Method and device for incorporating additional information into main information through electronic watermarking technique
Inventor: TARUGUCHI HIDEAKI
IPC: G06T1/00
Filed: 1998-07-07
Abstract: Two data units are selected from main information, such as MIDI data,  into which additional information is to be incorporated, to calculate a difference between respective values of the two data units.  A particular data segment to be incorporated into one of the MIDI data units is selected from a group of data of additional information.  The size of the data segment to be incorporated into one of the data units may be either one bit or two or more bits.  Substitute data  to  replace  the  content  of  one  MIDI  data  unit  is generated on the basis of a predetermined function using, as variables,  the  data-related  value  and  a  value  of  the particular data segment, and the content of the data unit corresponding to a predetermined one of the two MIDI data units is replaced by the generated substitute data.   Thus, through such an electronic watermarking technique, any desired additional information can be incorporated into the MIDI data without  changing  the  MIDI  data  format.     In  another implementation, data of encoding information, representative of an encoding procedure, are incorporated dispersedly into particular data units belonging to a predetermined first data group of the main information,  and data belonging to a predetermined second data group of the main information are encoded by the encoding procedure represented by the encoding information.
