A method for aligning a vehicle at a charging station may include determining the distance between each sensor of the plurality of sensors and a target surface of the charging station. The method may further include aligning the vehicle at the charging station using the determined distance data, and charging the electric vehicle at the charging station. The method may further include using the determined distances to align the side of the vehicle substantially parallel to the target surface.

A hearing assistance system includes an adaptive directionality controller to control a target direction for sound reception. The adaptive directionality controller includes a beamformer, a speech detector to detect off-axis speech being speech that is not from the target direction, and a steering module to steer the beamformer in response to a detection of the off-axis speech.

It is provided a system for localizing a sound source and a method therefor. The system includes a movable unit, being adapted for free movement and being integrated with a microphone; a motion tracking unit; and a processing unit, being adapted for receiving microphone signal and motion tracking unit signal and obtaining information on a direction from which sound from the sound source arrives using the microphone signal and motion tracking unit signal obtained during movement of the movable unit. By having the system and the method therefor, it is helpful for solving at least one of the technical problems: the complexity and a large volume of an acoustic camera for localization of a sound source; the restriction of the movement of the microphone in a sound source localization system.

A selection method is implemented in electronic equipment and includes steps consisting of: acquiring and memorizing, for each microphone of the equipment, a first reference audio signal produced by said microphone from a reception by the set of microphones of a first reference sound signal; analyzing the first reference audio signals to produce at least one directional parameter representative of a direction of arrival of the first reference sound signal; selecting, according to the directional parameters from among the set of microphones, the first microphones which make it possible to maximize an effectiveness of a first voice recognition method.

Systems, methods, and non-transitory computer readable medium are described for monitoring participant attentiveness within events and for group assortments. In some embodiments, communications received from an online participant of an event may be monitored. Based on the monitored communications, a steady state level may be determined. Changes within the monitored communications from the steady state level may be detected and then stored within an event participation log.

Disclosed are an electronic device and a method of operating the same. The electronic device includes: a housing: a user interface; at least one microphone disposed in the housing; at least one camera disposed in the housing; at least one driver comprising driving circuitry connected to or disposed in the housing and configured to move the housing; a wireless communication circuit disposed within the housing; a processor operatively connected to the user interface, the microphone, the camera, the driver, and the wireless communication circuit; and a memory operatively connected to the processor, wherein the memory stores instructions which, when executed by the processor, control the electronic device to: acquire a voice and/or an image of a user through the microphone and/or the camera, identify the user based on the voice and/or the image, identify an activity of the user based on at least one piece of movement information of the identified user, location information, or information on an object that the user is using, determine a location from which to track the user based on the identified activity, control the driver to move the housing based at least in part on the determined location, track the activity of the user based on continuity of the activity after movement, and provide a result of the activity based on the tracking result.

A computing system with multiple devices local to an environment facilitates active transfer among the multiple devices as a user moves about the environment. The devices may sense a presence or non-presence of the user and attempt to coordinate transfer to a device proximal to the user. In another implementation, the devices may communicate with a remote system that monitors a location of the user within the environment and causes content associated with the user to transfer between computing devices of the system based on the location and movement of the user.
