Abstract: A sensor for detecting conductive particles in a gas flow, comprising a substrate having two front sides, wherein a gas flow direction is from a first front side to a second front side, wherein a resistive electrode structure comprising at least two electrodes is formed on the substrate, the at least two electrodes are electrically separated, wherein in relation to the gas flow direction, a first electrode is arranged in a first section of the sensor such that the first electrode acts as a suction electrode, wherein a sensor detection region is formed in a second section of the sensor, whereby the sensor detection region is formed by portions of the first electrode and a second electrode, wherein the second electrode is formed at least partially in a third section of the sensor.

Abstract: A goods processing apparatus includes a controller including a program memory, a security module, a first communication interface that is configured to, in cooperation with the security module, securely communicate with a remote server, and an acoustic output device electrically connected with the controller and configured to output audio files or sound files. The security module and the first communication interface can be electrically connected with the controller. The program memory may store a program to control the acoustic output via the acoustic output device. The program can facilitate external commands being transmitted from the remote server, or from one or more other internet sources, to the controller. Via security measures, operational security of the goods processing apparatus is prevented from being negatively affected, or harmful code is prevented from being transmitted to controller.
