摘要： Described are techniques for determining whether a received audio signal is corrupted or a product of noise, prior to decoding the entire signal. An emitted audio signal may include initialization data, which includes a predetermined sequence of symbols, and which precedes encoded payload data. Correspondence between the predetermined sequence of symbols and expected symbols stored as confirmation data may be determined. If the correspondence indicates a match, an audio receiver may continue decoding the audio signal to access the payload data. If the correspondence does not indicate a match, the audio receiver may cease decoding, which may conserve power, computing resources, and time, ensuring that subsequent audio signals are not missed while the audio receiver decodes a false or corrupted signal.

摘要： Described are systems to manage the rate of energy delivery to computing devices. The computing devices may connect to a shared data and power distribution system. Techniques are described for distributing energy to the computing devices directly or via an energy and data delivery device using limits determined for the computing devices. Once the energy transfer to the computing devices is complete, the limits on the rate of energy delivery may be rescinded.

摘要： Knowing a location of a sensor or other device may be useful in a variety of settings. Described herein are devices and techniques for using modular sections of known dimensions that are configured to couple to one another at predetermined coupling positions. The modular sections may intercommunicate to provide data identifying adjacent modular sections, the respective coupling positions, and where on each of the modular sections a device is attached. By analyzing this data, two- or three-dimensional arrangement data of the modular sections and devices may be generated. Using information about the physical dimensions of the modular sections, spatial coordinates indicative of where the devices are located in space may be determined. As devices or modular sections are added, removed, or replaced, the arrangement and the corresponding spatial coordinates may be updated to reflect the changes.

摘要： Audio data and video data are processed to determine one or more audible events and visual events, respectively. Contemporaneous presentation of the video data with audio data may be synchronized based at least in part on the audible events and the visual events. Audio processing functions, such as filtering, may be initiated for audio data based at least in part on the visual events.

摘要： Multiple sensors are used to determine proximity of a user with respect to one or more media devices. Different types of sensors may determine different types of information regarding user proximity, such as presence or absence, proximity, distance, orientation, movement, identity, or a number of users that are detected. The information, sensor types, and times at which the information is acquired are used to generate data that associates specific devices, sensor types, information regarding user proximity, and the times at which the information is acquired. Instructions may be provided to various devices to cause performance of actions based on the generated data.

摘要： An activation signal is provided in response to a user gripping force incident to a grip switch. Electronic circuitry transitions from an inactive state to an active state in response to the activation signal. The activation signal may also include encoded information regarding user identity, gripping force magnitude, user input gesturing, and the like. The electronic circuitry may use the information encoded in the signal to select or perform particular functions or operations. Power consumption of a stylus, user device, or other apparatus is reduced, or various functions are improved, accordingly.

摘要： A system including an active stylus and a mobile computing device where an electronic signal emitted by the tip of the stylus that the mobile computing device uses to locate the tip is turned on and off when the stylus is not being used to save power. Whether the stylus is being used is determined based on an orientation of the stylus in comparison to an orientation of an electronic writing surface of the computing device. Difference in barometric air pressure or altitude between the stylus and mobile computing device may also be used to turn the tip signal on and off.

摘要： Data indicative of user proximity to one or more devices is provided to a server. Based on the proximity data, the server may modify content distribution to, or the behavior of, the one or more devices. In one implementation, determination that no user is proximate to the device may result in pausing or stopping streaming of content to the server.

摘要： Described are systems to manage energy distribution and operation of computing devices (“devices”). The devices may connect to a shared data and power distribution system, such as receiving electrical energy in conjunction with data signals using Power over Ethernet (POE). During activation of the facility, such as after an energy outage, the demand for energy from many devices attempting to startup may exceed the energy capacity available. Described are devices and techniques for distributing energy to devices, coordinating operating mode of the devices, and so forth, to mitigate demand spikes for electrical energy that exceed the capacity of the energy distribution system.
