Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for causing a transducer to transmit an acoustic input signal into a member of a device. Receiving a detection signal representing reverberations of the input signal traveling within the member from a receiver. Detecting a contact of the member with an object external to the member based on a change in the detection signal, where the change in the detection signal represents an alteration in the reverberations of the input signal caused by the contact of the member with the object. Determining a position along the member of a point of the contact of the member with the object based on the change in the detection signal.

A method and a system (110) for providing sound data for generation of an audible notification relating to power consumption at a site (120) are disclosed. The system receives (201) information about power consumption at the site (120); and The system determines (202) the sound data based on the information about power consumption and on preference of a user of the system (110). A corresponding computer program and a carrier therefor are also disclosed.

Disclosed is a method for managing an industrial production line, including at least one processing station and one monitoring station that is connected to the at least one processing station. The method includes: sending a radiofrequency signal from the monitoring station to a communication peripheral; then—sending a corresponding sound signal using the communication peripheral. The sound signal is dedicated to an operator to which the peripheral is assigned. The transmitted information is specific to the communication peripheral. Also disclosed is a corresponding device and facility.

A controller includes at least one memory, and at least one processor. The at least one processor is configured to acquire speech, recognize the speech, determine whether the speech is uttered in a quiet voice, and control a movable part of a controlled apparatus in accordance with a result of the speech recognition. The at least one processor is configured to control the movable part of the controlled apparatus such that a sound pressure level of a sound generated by the movable part of the controlled apparatus is lower when it is determined that the speech is uttered in the quiet voice than when it is determined that the speech is not uttered in the quiet voice.

A diagnostic apparatus determines, at a reference time, whether a device is normal or abnormal, and in which operation state the device is at the time. A reference data creation unit repeats a process of storing sensor values acquired from the device while changing the operation state at the reference time in association with each of the determined operation states until there is no non-corresponding operation state with which the acquired sensor value is not yet associated. At a diagnosis time at which it is not known whether the device is normal or abnormal, an operation state and a sensor value of the device at the time is acquired. The stored sensor value associated with the acquired operation state is read to compare the sensor value acquired at the diagnosis time with the read sensor value to display a result of determination on whether the device is normal or abnormal.

This disclosure relates to a mobile, autonomous audio sensing and analytics system and method for monitoring operating states in one or more environments including manufacturing, commercial, and residential environments. The autonomous audio sensing and analytics system comprises: a plurality of machines configured to listen and collect information; at least one autonomous audio sensing and analytic system configured to capture the listened and collected information; and a visualization system communicatively coupled to at least one or more of machines or the autonomous audio sensing and analytic system, wherein the autonomous audio sensing and analytic system communicatively coupled to more than one machine stores, classifies, estimates, and outputs the information to the visualization system for performing at least one of analysis operation or failure notification.
