摘要： Embodiments include a microphone array comprising a first plurality of directional microphone elements arranged in a first cluster formed by directing a front face of said microphone elements towards a center of the first cluster, and a second plurality of directional microphone elements arranged in a second cluster formed by directing a front face of said elements away from a center of the second cluster, wherein the first cluster is disposed vertically above the second cluster. Also provided is a microphone comprising a first microphone array comprising a plurality of directional microphone elements arranged in close proximity to each other and configured to capture near-field sounds within a first range of frequencies, and a second microphone array disposed concentrically around the first microphone array, the second array comprising a plurality of omnidirectional microphone elements configured to capture near-field sounds within a second range of frequencies higher than the first range.

摘要： In an example, the present technique provides a method for processing signals from a human user in connection with a sleep state. Preferably, the method includes using information from the signals for digital cognitive behavioral therapy to improve a sleep state of the human user. In an example, the method generally includes sensing of human activities, processing information from such sensing, outputting a task to the user, monitoring a reaction from the user, and adjusting any one of the aforementioned, to improve a sleep state of the user.

摘要： Systems and methods for distinguishing valid voice commands from false voice commands in an interactive media guidance application. In some aspects, the interactive media guidance application receives, at a user device, a signature sound sequence. The interactive media guidance application determines, using control circuitry, based on the signature sound sequence, a threshold gain for the current location of the user device. The interactive media guidance application receives, at the user device, a voice command The interactive media guidance application determines, using the control circuitry, based on the voice command, a gain for the voice command. The interactive media guidance application determines, using the control circuitry, whether the gain for the voice command is different from the threshold gain. Based on determining that the gain for the voice command is different from the threshold gain, the

摘要： Systems, video cameras, and methods for using audio sensors to control surveillance video capture are described. A video camera and audio sensor are deployed so that the audio sensor has an audio field that is at least partially outside the field of view of the video camera. The audio sensor collects audio data from the audio field and a controller for the video camera uses audio events from the audio data for modifying the video capture operations of the video camera. Video data is then captured based on the modified video capture operations, such as initiating video capture, changing the video capture rate, or changing the camera position.

摘要： Provided is a meeting speaker box for a mobile terminal. One end of a flip assembly is connected to a casing. A connector is disposed at another end of the flip assembly, and is configured to be plugged in and communicatively connected to the mobile terminal. The flip assembly is configured to enable the casing to rotate between a first position where the casing fits the screen of the mobile terminal and a second position where the casing fits the back of the mobile terminal. A first speaker is disposed in the casing and is configured to amplify the sound of the mobile terminal. A detection assembly is disposed in the casing and is configured to detect the position of the casing. A control unit is communicatively connected to the detection assembly and the first speaker.
