Abstract: The present application includes a system and method that provisions at least two (2) receivers in a topology that allows each receiver to acquire wireless communication signals through different diverse antenna fields. Each receiver acquires the signal, and demodulates, decodes and sends data to the data terminal component. The data terminal component resolves packet alignment issues and selects the best data. This improves system reliability and reduces the system susceptibility to data corruption or loss of data due to signal fading that might occur on a single antenna field. Provisioning a wireless system in this manner reduces the likelihood that the same fading phenomena, resulting from either multipath and/or shadowing affects, impair signal reception causing data dropout or loss of data.

Abstract: A unit for detecting an addition of a cleaning agent in a beverage dispenser, in particular in a coffee machine. In order to guarantee that a cleaning agent has been added when automatic cleaning is carried out, a measurement device is provided as well as a method of determining whether a cleaning agent has been added to the aqueous cleaning liquid. Whether a cleaning agent has been added to the aqueous cleaning liquid can be determined in dependence upon the measured conductivity and the measured electrical resistance of the cleaning liquid, respectively.

Abstract: A replaceable nozzle for use in high temperature environments. The nozzle includes a high-temperature-resistant, metal nozzle body that at least partially penetrates into the high temperature environment and a pipe that is connected to the nozzle body for supplying fluid. The nozzle also includes an expansion collar made of a high-temperature-resistant material, a nozzle block and a separating surface or a separating layer of high-temperature-resistant, elastic material. The expansion collar is designed to be disposed between the metal nozzle body and the nozzle block.
