Abstract: This application is applied to the autonomous driving field, and provides a signal receiving apparatus, a detection apparatus, and a signal processing method and apparatus. The receiving apparatus includes a first receiving branch; the first receiving branch includes a first detector and a signal coupling apparatus; the first detector is configured to output one branch of echo electrical signal; the signal coupling apparatus outputs at least two branches of echo electrical signals based on the branch of echo electrical signal output by the first detector; and one branch of echo electrical signal in the at least two branches of echo electrical signals has same signal strength as the branch of echo electrical signal output by the first detector.

Abstract: An antenna unit and an antenna array. The antenna unit includes M layers of cross metal patches, M layers of dielectric substrates, and a metal ground layer, where M is an integer greater than 1. In addition, an ith-layer dielectric substrate is disposed between an ith-layer cross metal patch and an (i+1)th-layer cross metal patch. The ith-layer cross metal patch, the ith-layer dielectric substrate, and the (i+1)th-layer cross metal patch are sequentially stacked, and i is an integer ranging from 1 to M?1. An Mth-layer cross metal patch, an Mth-layer dielectric substrate, and the metal ground layer are sequentially stacked. The antenna unit and the antenna array formed by units may have a good polarization feature, a relatively wide operating bandwidth, and a relatively good phase shift feature.

Abstract: The present disclosure discloses a brown rice and oat bread with low glycemic index and a preparation method thereof, which belongs to the technical field of grain processing. The brown rice and oat bread provided by the present disclosure includes the following ingredients: brown rice flour, gluten powder, oat flour, butter, sodium caseinate, salt, yeast, improver, and water. According to the present disclosure, the sodium caseinate is used to help form a dough and improve the flavor of the bread, and the brown rice and oat bread with low glycemic index is obtained with the brown rice bread recipe and special baking process, which is close to wheat bread in terms of specific volume, taste and tissue structure.

Abstract: An electronic system includes multiple I/O interfaces and a controller. The controller is coupled to multiple cards via multiple I/O interfaces respectively, and can select a card from multiple cards and perform a wireless communication to transfer data between the selected card and a target electronic device. The controller includes a configuration block and a core. The configuration block stores configuration data indicative of selecting which card. The core is coupled to the configuration block and the cards and can enable the wireless communication.
