Abstract: An electrochemical system comprises a plurality of stacked bipolar plates, each of which is composed of two structured half-plates that describe corrugation peaks and corrugation valleys. Coolant channels are formed between the half-plates of each bipolar plate by means of the corrugation peaks and corrugation valleys, and at the same time the outer faces of the bipolar plates delimit flow channels for operating media. A membrane assembly is located between each pair of bipolar plates. An assembly of flow channels, said assembly being mirror-symmetrical with respect to a plane on which the membrane assembly lies, transitions into an assembly which is offset in the transverse direction in a transition region between an active field and a distributing field of each bipolar plate.

Abstract: This document describes radiation channels filled with a dielectric using a surface with a pattern of radiation elements to allow electromagnetic energy to enter or escape the dielectric. An absorption channel is paired with the radiation channel. The absorption channel is loaded with an absorber material to allow for a transfer of electromagnetic energy between the radiation channels and the respective absorption channel. A surface of each of the absorption channels has a pattern of absorbing elements that allows the electromagnetic energy that enters or exits the dielectric to be absorbed by the absorber material.

Abstract: A multi-mode radar system with high isolation between modes is described herein. The radar system comprises a feed portion configured to propagate electromagnetic energy along an energy path. Connected to the feed portion is a divider portion that splits the energy path into a first energy path corresponding to first antennas and a second energy path corresponding to second antennas. The second antennas have one or more of: different operating frequencies, different polarizations, or different fields of view than the first antennas. By using respective filters in the first and second antenna portions, the radar system achieves multi-mode use (e.g., muti-frequency, multi-polarization, and/or multi-field-of-view) with high isolation between the modes. Furthermore, using a single feed port may save cost, have lower complexity, and allow for better space utilization.

Abstract: The techniques and systems herein enable ghost object detection. Specifically, a reflection line indicative of a potential reflection surface between first and second moving objects is determined. If enough stationary objects are within an area of the reflection line, it is determined whether one or more of the stationary objects within the area are within a distance of a reflection point. An expected velocity of the second object is then determined and checked against a velocity of the second object. If the expected velocity is near the velocity, it is determined that the second object is a ghost object. By doing so, the system can effectively identify ghost objects in a wide variety of environments, thereby allowing for downstream operations to function as designed.
