Video inspection systems are disclosed. In one embodiment a video camera for use in a pipe inspection system includes a camera head including an outer housing, a camera module assembly including video and non-video sensors, a processing circuit, and a data link receiver.

A sensor head transitions between a retracted and extended state. While retracted, sensors are covered. While extended, the sensors are exposed and may be used to acquire sensor data about the physical space. A force applied by a user, or a received command, may initiate transition. For example, a user may press on the sensor head to initiate retraction or extension. A motor provides a force to move the sensor head and generate haptic feedback, while a position encoder determines a displacement of the sensor head due to an external force being applied. Different applications of force by the user to the sensor head may result in different operations by the device. For example, a short push may retract the sensor head and disable the sensors for a specified time interval. In comparison a long push may retract the sensor head and disable the sensors until a specified clock time.

Introduced here are systems and methods to increase accuracy of speech recognition by utilizing multiple sensors placed at multiple speech transmission regions such as a user's lips, throat, ear canal, etc. The various speech transmission regions are better at transmitting certain phonemes, and a sensor placed close to a particular speech transition region can more accurately detect the phoneme transmitted through the particular speech transmission region. For example, a microphone placed close to the lips can better detect labial phonemes such as m, n, p, and b, than a microphone placed close to the throat. Further, disclosed here are ways to reduce energy consumption while performing speech recognition.
