Abstract: The method includes splitting a radio signal received at an in-vehicle antenna into two RF streams, and at the device under test, converting the first RF stream into a demodulated audio signal and transmitting it to the tester and recorder device. The tester and recorder device also receives the demodulated audio signal, determines a spectrum of frequencies over time, inputs the spectrum of frequencies into an artificial intelligence (AI) module of audio abnormality detection. The device also receives the second RF stream, converts it into a data signal, and records the data signal into a temporary storage memory. Then, when the AI module outputs of a positive detection of audio abnormality, the device transfers data from the temporary storage memory into a permanent storage memory, where the transferred data corresponds to a time window including the detected audio abnormality.

Abstract: Techniques are provided for auditing individual object operations as multiple file system operations. In an example, a client computer sends an object storage operation to a server that is configured to store data in a file system. The server receives the object storage operation, and converts it to one or more corresponding file system operations. The server opens an audit file context that identifies the object storage operation. As a file system driver reports that it has completed various file system operations corresponding to the object storage operation, the server appends an identification of the object storage operation, as determined from the audit file context, to an audit log entry for that file system operation.

Abstract: A client can allocate and reassociate unique identifiers to local content items associated with an account at a content management system, and use the unique identifiers to commit operations for the content items on the content management system. For example, a client can create a content item and determine the content item does not have an identifier from the content management system. The client obtains an identifier for the content item and asks the content management system to verify a uniqueness of the identifier. When the identifier is unique, the client adds a node corresponding to the content item to a local tree representing a state at the client of content items associated with the account, and uploads the content item with the identifier to the content management system. When the identifier is not unique, the client obtains a new identifier for the content item.
