One embodiment relates to testing and verifying vibrator motor operation during manufacturing of a device and during in-the-field use. The test relies on an integrated motion sensor or other mechanical measurement circuitry, such as, for example, an accelerometer. In one embodiment, a speed determination for a vibrator motor performance during initial manufacture of the device. Subsequently, when vibration is detected during the in-the-field use, the vibration may be sampled using the integrated mechanical measurement circuitry. Once sampled, a speed may be determined based on a resonance of the sampled signal. Over time, the various speed determinations for the vibrator motor may be analyzed to determine an overall health of the vibrator motor. A threshold for detecting when the overall health of the vibration motor over time has degraded may be predetermined. A notification of a degradation of vibrator motor performance is sent to either a manufacturer or user of the mobile communications device. Other embodiments are described and claimed.

Systems and methods are provided for a media device that controls input and output characteristics based on one or more associated conditions.

Personal media device input and output control based on associated conditions

An improved system and method for testing a sensor of a portable electronic device based on expected sensor data and not timing information. The system and method for testing a sensor of a portable electronic device retrieves sensed data from the portable electronic device (i.e. device under test) after the device has traversed a series of test areas or zones. The sensed data is compared against a set of expected sensor data patterns to determine which components of the sensed data correspond to each test area or zone. The sensor of the portable electronic device may be tested based on an association of the test areas or zones with segments of the sensed data.
