Abstract
(EN) A handheld system includes a reference pressure source configured to generate a reference pressure. The handheld system also includes a primary pressure source coupled to the reference pressure source. The primary pressure source is configured to generate a primary pressure in a primary pressure range. The primary pressure is less than the reference pressure, and the primary pressure is induced by the reference pressure source. The handheld system also includes a secondary pressure source coupled to the primary pressure source. The secondary pressure source is configured to generate a secondary pressure in a secondary pressure range. The secondary pressure is less than the primary pressure, and the secondary pressure is induced by the primary pressure source.
(FR) L'invention concerne un système portatif comprenant une source de pression de référence conçue pour générer une pression de référence. Le système portatif comprend également une source de pression primaire couplée à la source de pression de référence. La source de pression primaire est conçue pour générer une pression primaire dans une plage de pression primaire. La pression primaire est inférieure à la pression de référence, et la pression primaire est induite par la source de pression de référence. Le système portatif comprend également une source de pression secondaire couplée à la source de pression primaire. La source de pression secondaire est conçue pour générer une pression secondaire dans une plage de pression secondaire. La pression secondaire est inférieure à la pression primaire, et la pression secondaire est induite par la source de pression primaire.
