@ -1860,6 +1860,22 @@ The following fields are available:
- **MicArrayGeometry** Describes the microphone array, including the microphone position, coordinates, type, and frequency range. See [MicArrayGeometry](#micarraygeometry).
- **persistentId** A unique ID for this endpoint which is retained across migrations.
### MicArrayGeometry
This event provides information about the layout of the individual microphone elements in the microphone array.
The following fields are available:
- **MicCoords** The location and orientation of the microphone element.
- **usFrequencyBandHi** The high end of the frequency range for the microphone.
- **usFrequencyBandLo** The low end of the frequency range for the microphone.
- **usMicArrayType** The type of the microphone array.
- **usNumberOfMicrophones** The number of microphones in the array.
- **usVersion** The version of the microphone array specification.
- **wHorizontalAngleBegin** The horizontal angle of the start of the working volume (reported as radians times 10,000).
- **wHorizontalAngleEnd** The horizontal angle of the end of the working volume (reported as radians times 10,000).
- **wVerticalAngleBegin** The vertical angle of the start of the working volume (reported as radians times 10,000).
- **wVerticalAngleEnd** The vertical angle of the end of the working volume (reported as radians times 10,000).
## Census events
@ -7096,6 +7112,18 @@ The following fields are available:
- **IsValidDumpFile** True if the dump file is valid for the debugger, false otherwise
- **ReportId** WER Report Id associated with this bug check (used for finding the corresponding report archive in Watson).
### Value
This event returns data about Mean Time to Failure (MTTF) for Windows devices. It is the primary means of estimating reliability problems in Basic Diagnostic reporting with very strong privacy guarantees. Since Basic Diagnostic reporting does not include system up-time, and since that information is important to ensuring the safe and stable operation of Windows, the data provided by this event provides that data in a manner which does not threaten a user’s privacy.
The following fields are available:
- **Algorithm** The algorithm used to preserve privacy.
- **DPRange** The upper bound of the range being measured.
- **DPValue** The randomized response returned by the client.
- **Epsilon** The level of privacy to be applied.
- **HistType** The histogram type if the algorithm is a histogram algorithm.
- **PertProb** The probability the entry will be Perturbed if the algorithm chosen is “heavy-hitters”.
