Title: Capacitance transducer
Inventor: MOHAUPT UDO HORST
IPC: G01G7/06
Filed: 1995-11-16
Abstract: A capacitance transducer for use in measuring loads is provided herein. It comprises a first electrode and a second electrode having overlapping surface areas spaced apart by a first solid or rigid dielectric and a second fluid dielectric. The first and second electrodes are so oriented that increasing force which is applied to the transducer resiliently presses an increasing portion of overlapping surface areas of the first and second electrodes into close proximity separated by the first dielectric while substantially removing the second dielectric from the areas of close proximity. This causes a capacitance response that depends significantly on the size of areas which are pressed together relative to any capacitance response resulting from a change in the spacing of the electrodes.

Patent CA-2174007-A1 (CA)
Inventor: ALAIN MICHEL
IPC: A63H33/06
Filed: 1996-04-12
Abstract: Un jeu de constructions articulées, composé de nodes reliées par des membrures, qui propose une série de modèles géométriques tri-dimentionnels. Ces modèles géométriques articulés sont constitués de réseauxd'assemblages qui définissent les liens prévilégiés entre les nodes. Ces réseauxd'assemblages déterminent des espacements constants entre les points qu'ils associent et pour lesquels ils modulent le comportement pour produire des ensembles ou modèles plus ou moins complexes qui s'articulent selon des séquences de transformations. La lecture des séquences de transformations a des conséquences significatives qui permettent de les associer à des formes de polyèdres réguliers, lorsque les réseaux d'assemblage déterminent des espacements égaux. Ces conséquences significatives sont traités comme des états corollaires des systèmes. Les réseaux d'assemblages sont regroupés en systèmes selon le nombre de quadrants qu'ils occupent en tant qu'ensembles symmétriquement répartis autour d'un point d'origine. Le comportement des modèles géométriques articulés exprime des transformations rythmiques. Ce rythme est cyclique et oscillatoire. Il se traduit par la contraction et l'expansion de certaines parties des modèles, selon la phase du cycle, ou par des mouvements axiaux, d'allure stellaire, par d'autres parties des mêmes modèles. Ce brevet s'inscrit dans une démarche entreprise pour déterminer un code géométrique.
