    摘要: A pressure sensor includes: a measuring cell having a base plate and a measuring membrane connected along its edge with the base plate, and means for generating an electrical quantity dependent on deformation of the measuring membrane; a circuit for registering the electrical quantity; and a capsule having a capsule body and a sealing element, with which the capsule is hermetically sealed along a joint. The capsule encloses the circuit, in order to protect such from influences of moisture; and the joint of the capsule is mechanically decoupled from the base plate. The mechanical decoupling of the joint means, for example, that at least the axial support of the pressure measuring cell in a housing is not allowed to be transferred through the joint. Despite arranging of the capsule on the base plate, pressure-related and temperature-related distortions of the base plate are not permitted to have any effects on the joint of the capsule.

    摘要: A temporal database system, method, and computer-readable storage medium in which a database is provided with sets of entities defined by initial tuples having a set ID, a unique timestamp, and a member increment. A write transaction is performed for sets of entities, wherein the write transaction designates the set by said set ID and produces an increment, wherein the increment is a number of entities to be added to or removed from the designated respective set of entities. New tuples including the set ID, the increment, and a new unique timestamp are created for the write transaction. Following the write transaction, an asynchronous compaction operation is performed on the new tuples. The compaction operation aggregates the increment of each new tuple into summary point counts. The compaction operation facilitates efficient queries without contention with write transactions.

    摘要: A method for reducing the content of foreign molecules in gaseous or liquid form dissolved in a pressure transfer liquid of a pressure measuring transducer. A pressure receiving chamber is closed by an isolating diaphragm. A pressure measuring chamber is connected to the pressure receiving chamber, and a pressure sensor arranged in the pressure measuring chamber, in which the liquid serves to fill an inner space of the pressure measuring transducer formed by the pressure receiving chamber is provided. The pressure measuring chamber is connected therewith, and transfers an external pressure acting on the isolating diaphragm to the pressure sensor in measurement operation. The liquid is brought into contact with at least one adsorptive body, and foreign molecules dissolved in the liquid are bound to the adsorptive bodies by adsorption.
