Abstract: L'invention porte sur un système capacitif de détection de la pression et de la température destiné à produire des signaux représentatifs de la pression absolue d'un fluide organique à un endroit choisi et dans des conditions opératoires ambiantes, y compris de la température corporelle, à cet endroit. Un conducteur implantable doté d'un module de détection sur son extrémité distale est couplé à un moniteur qui alimente un circuit de détection dans le module de détection, démodule et mémorise les données sur la pression absolue et la température dérivées des signaux produits par ce circuit. Le module de détection comporte un condensateur de détection qui modifie la capacité selon les changements de pression et un condensateur de référence, relativement insensible aux changements de pression. Le circuit de détection fournit un courant de charge qui change avec les variations thermiques à l'emplacement de l'implant, charge et décharge alternativement les deux condensateurs et produit des impulsions de rythme dont il est possible de distinguer les paramètres à la fin de chaque cycle de charge qu'il transmet au démodulateur. Le démodulateur détecte et synchronise les impulsions de rythme, et il dérive des valeurs analogiques de tension de la pression et de la température, valeurs représentatives des intervalles existant entre les impulsions de rythme qui sont numérisées et que mémorise le moniteur. Il est également possible de coupler le moniteur à d'autres détecteurs destinés à mesurer et à mémoriser des paramètres connexes corporels chez un patient, tels que les gaz dans le sang, un électromyogramme et l'activité du patient.

Patent CA-2198157-C (CA)
Inventor: KNAPPERS MICHAEL A
IPC: F02M21/06
Filed: 1997-02-21
Granted: 2002-11-05
Abstract: A fuel vaporizer and method of fuel vaporization are discribed for use with a fuel such as propane, that is know to tend to liquefy at low temperatures and to vaporize at high temperatures. The vaporizer and method described pertain to a series of internal walls and cavities which promote heat-exchange and transfers heat from a fluid engine coolant to the fuel. The transfer of heat and vaporization of fluid occurs by virtue of movement of the fuel through a series of countercurrent passages created by the walls and cavities, with increasing cross-sectional dimensions in the passages to accomodate the expansion of fuel from the liquid to the gaseous state. The heat is transferred by conduction across a metallic interface which forms part of the vaporizer and which separates the fuel from the coolant.

Abstract: There is a hardware configuration with processing units (CTR0, CTR1) operated in microsynchronous parallel operation for the processing of ATM information which are connected at the ATM end to a switching matrix (SN0, SN1) and via a bus interface (B-I) to a central processor which is used for evaluating error statistics arising in the processing units and for monitoring the synchronous operation by comparing the processing results. The error statistics data are packed into ATM transmitter cells and looped back via the switching matrix in each case to both processing units and then supplied to the central processor via the bus interface. This prevents the erroneous indication of the loss of microsynchronism when error statistics for the two processing units differ (Figure).
