摘要： Methods and apparatuses for representing a sound field in a physical space are provided and described as embodied in a system that includes a sound transducer array along with a touch surface-enabled display table. The array may include a group of transducers (multiple speakers and/or microphones). The array may be configured to perform spatial processing of signals for the group of transducers so that sound rendering (in configurations where the array includes multiple speakers), or sound pick-up (in configurations where the array includes multiple microphones), may have spatial patterns (or sound projection patterns) that are focused in certain directions while reducing disturbances from other directions.

摘要： A wireless communication system and related techniques and apparatuses are disclosed that predict future disconnections or other connection impairments with end-user portable devices in advance so that service interruptions can be handled more gracefully. The system can predict the loss of service based on user-usage information associated with the portable device, such as the current GPS location of the device, its direction and velocity of travel, a user calendar, user habits and other information, such as the time of day, weather conditions, or wireless network coverage maps. An impairment handling method is selected that alters the content presented by the portable device. The impairment handling method is executed by the system upon detecting the impairment of the wireless connection so that the content is altered during occurrence of the impairment. The alteration of the content is done to mitigate the user-perceived effect of the impairment.

摘要： In general, techniques are described for performing constrained dynamic amplitude panning in collaborative sound systems. A headend device comprising one or more processors may perform the techniques. The processors may be configured to identify, for a mobile device participating in a collaborative surround sound system, a specified location of a virtual speaker of the collaborative surround sound system and determine a constraint that impacts playback of audio signals rendered from an audio source by the mobile device. The processors may be further configure to perform dynamic spatial rendering of the audio source with the determined constraint to render audio signals that reduces the impact of the determined constraint during playback of the audio signals by the mobile device.
