A receiver discriminates the signals sent from own transmitters and multiple reflections to detect objects of interest. In addition, the receiver discriminates signals transmitted from different systems on other vehicles. This requires the receiving system to have knowledge of the codes transmitted by the other vehicle. The receiving system determines the information bits sent by the other vehicle. If multiple radar systems on multiple vehicles use different sets of codes (but known to each other), the multiple systems can create a communication infra-structure in addition to radar detection and imaging. |

Inline message composing with visible list view
A compose form for drafting a message is presented inline within a window along with a message list. For example, instead of overlaying the message application's user interface (UI) with a new window for composing a message, the compose form is displayed within a portion of the window reserved for viewing content of messages. While composing the message using the compose form, the rest of the message application's UI remains visible and accessible to the user. For example, the user may navigate to another folder and/or move to another message/conversation by interacting with the tree view/message list view. A draft of the message being composed may be automatically saved when the user navigates away from the compose form (e.g. by selecting another conversation in the list view). |
