Abstract: A reflection apparatus includes a base plate, where one side is used to dispose a radiation unit, and the other side is used to dispose a feeding network; a first side plate and a second side plate that are separately connected to the base plate and that are disposed opposite to each other, where the first side plate and the second side plate each extend relative to the base plate and toward the side used to dispose the feeding network; a first return plate connected to the first side plate, where the first return plate extends relative to the first side plate and toward a direction of the feeding network; and a second return plate connected to the second side plate, where the second return plate extends relative to the second side plate and toward the direction of the feeding network.

Abstract: The present invention relates to novel fungicidal compositions, to their use in agriculture or horticulture for controlling diseases caused by phytopathogens, especially phytopathogenic fungi, and to methods of controlling diseases on useful plants.

Abstract: The present disclosure relates to two-dimensional antennas and network devices. One example antenna includes a reflection panel, at least two antenna arrays, at least one common feeding network, and at least two array feeding networks. The at least two antenna arrays are on the reflection panel. Each antenna array comprises at least one independent radiation unit and at least one common radiation unit. Each antenna array corresponds to an array feeding network of the at least two array feeding networks. Each independent radiation unit in each antenna array is connected to a particular array feeding network corresponding to the particular antenna array. Each common radiation unit in each antenna array is connected to the at least one common feeding network. The at least one common feeding network is connected to the at least two array feeding networks corresponding to the at least two antenna arrays.

Abstract: A method for securely receiving a cipher key from a key provider to a key requester is provided. The method includes generating a session key shared between the key requester and the key provider, determining at least one key in accordance with the session key. The method also includes transmitting a request from the key requester to the key provider, and receiving a response from the key provider, where the response comprises an encrypted payload and an authentication tag. The method also includes authenticating the response and decrypting the encrypted payload using the at least one key to obtain the cipher key.

Abstract: A staple for attaching together first and second metal sheets is made of a length of round wire bent at the ends to form spaced apart depending metal legs, each having a metal piercing point at the end thereof adapted to pierce completely through the first sheet and at least partially through the second sheet and also adapted to spread the legs further apart during the piercing to a spread position in which the legs are anchored within the metal sheets and thereby attach the metal sheets together. The metal piercing points each having an outside bevel surface on the outside of the leg, an inside bevel surface on the inside of the leg, and a blunt end surface between the inside and outside bevel surfaces.
