A system includes a plurality of acoustic sensor elements co-located with one another, each acoustic sensor element of the plurality of acoustic sensor elements being configured to generate a signal representative of sound incident upon the plurality of acoustic sensor elements, and a processor configured to determine data indicative of a location of a source of the sound based on the signals representative of the incident sound. The plurality of acoustic sensor elements include a directional acoustic sensor element configured to generate a signal representative of a directional component of the sound.

The present invention generally relates to an attachment for a firearm that communicates with remote device or person such as emergency services. One embodiment of the present invention is selectively interconnected to a picatinny rail, weaver rail, or other mounting means, and the embodiment includes a button that allows a user to initiate communication with emergency services without removing his or her hands from the firearm.

A method includes determining a plurality of voice assistance systems located in a plurality of environments and receiving, from a headset of a user, a voice command from the user. The voice command lacks an identifier for a first voice assistance system of the plurality of voice assistance systems in a first environment of the plurality of environments. The method also includes predicting, based on the voice command, a subset of the plurality of voice assistance systems for executing the voice command and communicating, to the headset, images of environments of the plurality of environments in which the subset of the plurality of voice assistance systems are located. The method further includes detecting that the user selected, from the images, an image of the first environment that contains the first voice assistance system and in response, communicating the voice command to the first voice assistance system.

Methods and systems for processing voice commands are disclosed. A voice controlled device may receive audio data comprising a voice command. Location information indicative of the source of the audio data may be determined. One or more devices may be caused to determine signals based on the location information. The one or more devices may receive thermal data in response to the signals. The thermal data may be analyzed to determine if the thermal data indicates the presence of a person at the expected location. If a person is detected, then the audio data may processed to cause the voice command to be executed.

A sound detector system has one or more microphone positioned with a field of regard of 360°. The system further has a processor to translate a sound into data indicative of a direction and transmit the data indicative of direction. Additionally, the system has a handheld device configured to wirelessly receive the data indicative of the direction and display data identifying the field of direction to a user.

An acoustic vector sensor has an array of sensors to detect at least the bearing of a target. The acoustic vector sensor or hydrophone with sensor array avoids the need to deploy multiple hydrophones each with a single sensor. The array of sensor signals can be processed using any one of a number of methods.

Example methods and systems for displaying one or more indications that indicate (i) the direction of a source of sound and (ii) the intensity level of the sound are disclosed. A method may involve receiving audio data corresponding to sound detected by a wearable computing system. Further, the method may involve analyzing the audio data to determine both (i) a direction from the wearable computing system of a source of the sound and (ii) an intensity level of the sound. Still further, the method may involve causing the wearable computing system to display one or more indications that indicate (i) the direction of the source of the sound and (ii) the intensity level of the sound.

A data-processing method for determining at least one spatial coordinate of a sound source emitting a sound signal, in a three-dimensional space, includes the following steps: obtaining at least one first signal and one second signal from the sound signal, collected according to separate directivities by a first sensor and a second sensor; deducing from the first and second signals an expression of at least one first spatial coordinate of the sound source, the expression comprising an uncertainty; determining additional information relating to the first spatial coordinate of the sound source, from a comparison between the respective features of the signals collected by the first and second sensors; and determining the first spatial coordinate of the sound source on the basis of the expression and the additional information.
