Abstract: Techniques for cleaning and calibrating a microphone are discussed herein. For example, a computing device can implement a microphone component to operate a speaker adjacent to a microphone to cause removal of an obstruction (e.g., rain, mud, dirt, dust, snow, ice, animal droppings, etc.) on or near the microphone. The microphone component can also or instead cause the speaker to output a frequency for testing operation of the microphone. By implementing the cleaning and/or calibrating techniques described herein, foreign particle(s) of varying size and type can be dislodged from an area near the microphone to improve performance of the microphone.

Abstract: Systems and techniques for detecting and locating low impact collisions, such as relatively low energy impact collisions involving an autonomous vehicle, are disclosed herein. Sensor data from audio sensors configured on a vehicle may be used to determine whether a threshold number of such sensors have detected sounds associated with a collision. Scores determined for the sensors based on audio energy and confidence values can be used to determine a location estimate for the detected collision.

Abstract: An impact is detected with a vehicle having a body comprising parts which are deformable in an impact, by a secondary impact detection system configured to detect an impact that may not trigger a primary impact detection system. The secondary impact detection system comprises a plurality of deformation sensors attached to the deformable parts and configured to detect bending of the deformable parts. One or more processors are configured to receive a plurality of respective outputs from the plurality of deformation sensors, process the respective outputs to increase sensitivity to short-term changes relative to long-term changes and generate an indication of an impact dependent on detecting a processed output meeting a predetermined criterion. Outputs associated with a group of neighboring flex sensors may be used to localize the impact, characterize the source of impact, and/or reduce a likelihood of a false positive associated with the detection.
