Inventor: NIELSEN KARSTEN
IPC: H03F3/217
Filed: 1998-04-01
Abstract: To correct for any source of non-linearity and noise introduced in the power amplification of a pulse modulated signal, a correction unit is applied in-between the pulse modulator and the switching power amplification stage. The correction unit is controlled to have a compensating effect, by introducing continuous delays on the individual pulse edges on the basis of error information provided by an error processing block. One preferred embodiment of the invention comprises: a Correction Unit with means to control the delays of the individual pulse edges as a function of a control input signal v e; a state feedback block A with compensation; a reference shaping block R to modify the pulsed reference v r; for optimized error estimation; a difference block to generate an error signal and a compensator C to shape this error. The invention makes it possible to implement practical digital to analog power conversion, with efficient compensation of any non-linearity and noise introduced in the switching power stage and filter, such that great efficiency, high performance and low system complexity is combined. Applications are direct digital to audio power conversion and improved general DC-DC or DC-AC power conversion systems controlled from the digital domain.

Patent CA-2293857-A1 (CA)
Inventor: LI HUI
IPC: G01D5/14
Filed: 2000-01-04
Abstract: An apparatus for sensing the absolute angular position of a rotatable shaft comprising one or more screw threads on the shaft or a screw-threaded shaft mechanically linked to the rotatable shaft so as to rotate in predetermined relationship to the rotation of the rotatable shaft, a permanent magnet, and an array of preferably four equally axially spaced magnetic field sensors positioned between the screw thread and the magnet along a line parallel to the axis of the screw-threaded shaft and at a distance apart of less than the thread pitch divided by the cosine of the helical angle, and positioned close to the screw thread. A determination of the instantaneous magnetic field strength between each sensor and the screw threads enables a computation of the radial distance between the sensor and the screw threads; together, the array of sensors establish preferably four discrete radial distance measurements from which the absolute angular position of the shaft can be computed using previously known signal processing circuitry and computations.

Title: Diagnostic methods and kits for the evaluation of the sympathetic nervous system function
Inventor: ROBERGE ANDREE G
IPC: C12Q1/26
Filed: 1998-05-28
Abstract: The present invention relates to an in vitro diagnostic method for the determination of specific dopamine-.beta.-hydroxylase activity for the evaluation of the sympathetic nervous system function of a patient from a serum sample; which comprises the steps of: a) filtering the serum sample to substantially remove drugs and endogenous inhibitors of dopamine-.beta.-hydroxylase; b) incubating the filtered sample of step a) with a substrate of dopamine-.beta.-hydroxylase for conversion in a detectable compound; c) determining the amount of detectable compound to evaluate dopamine-.beta.-hydroxylase activity and comparing with a normal sample; whereby an amount lower than a normal sample is indicative of a reduced sympathetic nervous system function and an amount higher than a normal sample is indicative of an increased sympathetic nervous system function. A reduction in the sympathetic nervous system function is indicative of neurodegenerative, neuroendocrine, psycho-affective and cardiovascular diseases, burn-out, and chronic fatigue, and the effects of stress such as panic syndrome. An increase in the sympathetic nervous system function is indicative of the effects of stress.

Title: Procede et dispositif pour le traitement de dechets, comprenant une separation par triage en plusieurs etapes de fractions legeres a partir d'une matiere sechee
Inventor: SCHMIDT HANS
IPC: B07B4/04
Filed: 2000-01-04
Abstract: A des fins de séparation de fractions légères organiques à partir de déchets qui sont soumis dans un premier temps à un traitement préalable constitué par un broyage préalable, une extraction des métaux ferreux, un broyage ultérieur, une extraction supplémentaire des métaux ferreux, un séchage et une extraction des métaux non ferreux, on dispose de manière échelonnée en forme de cascade plusieurs séparateurs pneumatiques, de préférence ce que l'on appelle des séparateurs pneumatiques verticaux en zigzag, que traverse successivement le courant de matière à séparer. On règle de manière échelonnée la vitesse d'écoulement de l'air dans les séparateurs individuels de telle sorte que le premier séparateur obtient la vitesse de l'air la plus petite et que le dernier séparateur obtient la vitesse de l'air la plus grande. Ainsi, de manière successive, d'abord les fractions légères organiques fines, ensuite les fractions légères organiques moyennes et enfin les fractions légères organiques grossières s'évacuent vers le haut à partir des étages de séparateurs respectifs. Les fractions légères organiques séparées représentent des composants combustibles possédant un pouvoir calorifique élevé. L'évacuation inférieure qui subsiste à partir du groupe de séparateurs est constituée par un mélange de fractions lourdes organiques et de matières minérales. Ce mélange de matières est séparé au moyen d'une séparation balistique en fonction de la densité en une fraction lourde organique et en matières minérales. La fraction lourde organique représente également un composant combustible possédant un pouvoir calorifique élevé. Les groupes de matières non combustibles que l'on obtient dans le procédé dans son ensemble, tels que les métaux ferreux, les métaux non ferreux, l'eau et les matières minérales, peuvent être mis en ouvre sous forme de matières recyclées.
Patent CA-2298780-A1 (CA)
Inventor: FREY BRADLY GEORGE
IPC: G06F12/08
Filed: 2000-02-16
Abstract: A special 'I/O' page, is defined as having a large size (e.g., 4K bytes), but with distinctive cache line characteristics. For DMA reads, the first cache line in the I/O  page may be accessed, by a PCI Host Bridge, as a cacheable read and all other lines are non-cacheable access (DMA Read with no intent to cache). For DMA writes, the PCI Host Bridge accesses all cache lines as cacheable. The PCI Host Bridge maintains a cache snoop granularity of the I/O  page size for data, which means that if the Host Bridge detects a store (invalidate) type system bus operation on any cache line within an I/O page, cached data within that page is invalidated (L1/L2 caches continue to treat all cache lines in this page as cacheable. By defining the first line as cacheable, only one cache line need be invalidated on the system bus by the L1/L2 cache in order to cause invalidation of the whole page of data in the PCI Host Bridge. All stores to the other cache lines in the I/O Page can occur directly in the L1/L2 cache without system bus operations, since these lines have been left in the 'modified' state in the L1/L2 cache.
