Abstract: A particle sensor for detecting particles in a flow of a measuring gas for detecting soot particles in an exhaust gas channel of a burner or of an internal combustion engine. The particle sensor includes a device for generating or for supplying laser light, a device for focusing laser light, and a device for detecting or transferring thermal radiation. The particle sensor includes at least one optical access, which separates an area exposed to the measuring gas from an area facing away from the measuring gas not exposed to the measuring gas, the device for generating or supplying laser light and/or the device for detecting or for transferring thermal radiation being situated in the area facing away from the measuring gas, wherein the particle sensor removes a sub-flow from the measuring gas flow and supplies it to the laser focus and further fluidically shields the optical access from the sub-flow.

Abstract: A portable gas analysis device having a separating column and a detector. The separating column is composed as a multi-capillary unit from parallel individual capillaries and, depending on the length, is bent into a compact shape, preferably even wound into multiple turns. A thermally conductive casing and a thermal stabilizing device are provided for the multi-capillary unit. The thermal stabilizing device comprises a temperature sensor, a heating element and control electronics. The casing protects the sensitive multi-capillary unit from mechanical actions; it acts as a protective space. The temperature-controlled casing also forms a space in which uniform and controlled conditions prevail and which in particular is isolated from the temperature and humidity of the environment, allowing reliable measurements outside a laboratory environment, in the field. This double effect of the casing for the capillaries in conjunction with the compact dimensions forms the true essence of the invention.

Abstract: Embodiments may be associated with a secure, distributed transaction ledger. The system may include a Database that contains electronic records providing JSON schema content format requirements. A computer processor of a content validation smart contract creation platform, coupled to the JSON schema data store, may access information in the JSON schema data store. The content validation smart contract creation platform may then automatically create a content validation smart contract based on the JSON schema content format requirements. The content validation smart contract may then be deployed by the content validation smart contract creation platform to the secure, distributed transaction ledger.
