Abstract: Techniques for collecting and displaying sensor data captured by a spatially representative sample of sensors requested in a search query are described. The sensors are represented in an index structure (e.g., a data tree). In response to a query, the index structure is leveraged to identify a subset of sensors that exhibits a similar spatial distribution to the original full set of sensors. Sensor data is then collected from the subset of sensors by probing the sensors or retrieving recently cached data located by the index and returned to satisfy the query. In this manner, the number of sensors to be probed is reduced, thereby reducing latency involved with polling a large number of sensors and making the search process more efficient.

Joint diagnostic expressions that imply one of the original diagnosis expressions are discarded. Otherwise, they are added to an updated disjunction of diagnostic expressions. All remaining diagnostic expressions in the temporary disjunction of diagnostic expressions are then added to the updated disjunction of diagnostic expressions, and a status report is produced.

Performing the operator authentication only when necessary can prevent illicit access to the in-device information without degrading the operability.

Abstract: A trace test and debug system for a target processor generates a program counter trace stream, a timing trace stream and a data trace stream. The target processor has three states, a program code execution state, an interrupt service routine code execution state, and a state where code execution is halted. The trace streams can be controlled so that the timing trace stream can be generated or excluded during the code execution halts. Similarly, when the timing trace stream is enabled for the interrupt service routine(s), the program counter and data trace streams can be selectively generated or excluded. The contents of the pipeline flattener can be held or flushed code execution halt depending on whether the pipeline is unprotected or protected. When the contents of the pipeline flattener are held during a code halt, the program counter trace stream and data trace stream is halted even if the timing trace stream remains active.
