Abstract: Methods and devices provide physiological movement detection, such as gesture, breathing, cardiac and/or gross body motion, with active sound generation such as for an interactive audio device. The processor may evaluate, via a microphone coupled to the interactive audio device, a sensed audible verbal communication. The processor may control producing, via a speaker coupled to the processor, a sound signal in a user's vicinity. The processor may control sensing, via a microphone coupled to the processor, a reflected sound signal. This reflected sound signal is a reflection of the generated sound signal from the vicinity or user. The processor may process the reflected sound, such as by a demodulation technique, to derive a physiological movement signal. The processor may generate, in response to the sensed audible verbal communication, an output based on an evaluation of the derived physiological movement signal.

Abstract: A system detects when sensors have become detached from equipment being monitored by the sensors. At least one sensor, such as a temperature sensor or an accelerometer, is mounted or otherwise positioned on equipment for monitoring operation of the equipment, and the sensor is coupled to a controller that may be configured to receive sensor data from the sensor. Based on the sensor data or otherwise, the controller is configured to detect when the sensor has become inadvertently detached from the equipment being monitored and notifies a user in response to such detection. The user may then take corrective action, such as reattaching the sensor to the equipment or replacing the sensor. Thus, detachment of the sensor from the equipment being monitored may be quickly detected and remedied, thereby reducing the amount of time that a sensor is unknowingly providing inaccurate information about the operation of the equipment.
