  • Patent number: 9454918
    Abstract: Example techniques are disclosed for processing of animal calls. For example, sound can be matched to one or more reference calls to identify whether the sound matches the reference calls. In one example, a user operates an animal calling device and is provided with feedback on whether they have correctly operated the calling device, e.g., whether they sound like the animal they are trying to emulate. In another example, a trail camera is provided that generates a log of animal calling activity while taking pictures of animals moving through a given area.

A memory card control device noncompliant with the memory card initializes the interface reset signal to a memory card to a second electric potential, and then when the memory card control device detects a first electric potential of the card detection pin of the memory card, the memory card control device determines that the memory card is mounted. When the memory card is mounted in such a memory card control device, the memory card control device does not detect the mounting of the memory card, and thus does not start subsequent operation such as driving the interface reset signal to the first electric potential and supplying electric power to the memory card.

  • Patent number: 9350700
    Abstract: A watermark generator for providing a watermark signal in dependence on binary message data includes an information processor configured to provide, in dependence on information units of the binary message data, a first time-frequency domain representation, values of which represent the binary message data. The watermark generator also includes a differential encoder configured to derive a second time-frequency domain representation from the first time-frequency-domain representation, such that the second time-frequency-domain representation includes a plurality of values, wherein a difference between two values of the second time-frequency-domain representation represents a corresponding value of the first time-frequency-domain representation, in order to obtain a differential encoding of the values of the first time-frequency-domain representation.

  • Patent number: 9351069
    Abstract: An example system may include a first mixer module configured to receive a latency-tolerant audio signal, buffer the latency-tolerant audio signal for a first duration, and process the latency-tolerant audio signal. The system may also include a second mixer module configured to receive the processed latency-tolerant audio signal from the first mixer module. The second mixer may also be configured to receive a latency-sensitive audio signal, where the latency-sensitive audio signal is shorter in duration than the latency-tolerant audio signal, and where the latency-sensitive audio signal corresponds to a user input. The second mixer may also be configured to buffer the latency-sensitive audio signal for a second duration, where the second duration is shorter than the first duration. The second mixer may also be configured to process the latency-sensitive audio signal, and combine the processed latency-tolerant audio signal and the processed latency-sensitive audio signal to create a combined signal.

  • Patent number: 9338395
    Abstract: A display allocation method is disclosed herein. The display allocation method is applied to a display in a conference meeting and comprises the following steps: allocating a first, a second and a third image block on the display, in which sizes of the first and the second image block are larger than size of the third image block; detecting an effective sound of a first candidate video corresponding to the third image block to identify whether the first candidate video is effective; setting one of the first and the second image block as a primary image block, and setting another one of the first and the second image block as a secondary image block, in which the secondary image block includes a secondary video; and allocating the first candidate video and the secondary video to the secondary and the third image block respectively if the first candidate video is effective.

  • Patent number: 9329831
    Abstract: Examples described herein involve expanding playback of a media item from a first playback device to a second playback device. In one example, a first playback device of a first zone, identifies a second playback device within a proximity of the first playback device, determines that the second playback device is playing a media item as part of a second zone, and based on the determination, joins the second zone and begins playing the media item in synchrony with the second playback device. In another example, a first playback device, while playing a media item as part of a first zone, determines that a second playback device of a second zone has entered a proximity of the first playback device, and responsively, causes the second playback device to join the first zone and begin playing the media item in synchrony with the first playback device.

  • Patent number: 9331799
    Abstract: A method and device for synchronously playing audio data over a number of audio playback devices that are connected to a network. The distribution of particular audio data to a plurality of audio playback devices that are adapted to play audio, where the audio playback devices are all connected to a network over which audio data is delivered from a digital audio source to the audio playback devices, can be accomplished by determining when more than one of the audio playback devices has been directed to play the particular audio data, and in response to the determination directing that two or more of the audio playback devices synchronously play the particular audio data.

  • Patent number: 9330546
    Abstract: In an embodiment, a system and method for automatically converting a plurality of events in a plurality of channels in a structured representation sequence into haptic events. The method comprises calculating an event score for each event of the sequence in one or more channels. The method also comprises calculating a cumulative score based on the event scores in the one or more channels. The method includes selectively designating haptic events to the events based on the event scores in one or more selected channels, wherein the haptic events are output by a haptic actuator. This may be done by the system by calculating properties of the sound or by taking already existing values associated with those properties to efficiently produce haptic events.

  • Patent number: 9324313
    Abstract: A wearable computing device can receive, via at least one input transducer, a first audio signal associated with ambient sound from an environment of the device. The device can then process the first audio signal so as to determine a second audio signal that is out of phase with the first audio signal and effective to substantially cancel at least a portion of the first audio signal. The device may then generate a noise-cancelling audio signal based on the second audio signal, based on a third audio signal, and based on one or more wearer-specific parameters, where the third audio signal is representative of a sound to be provided by the device. The device may then cause a bone conduction transducer (BCT) to vibrate so as to provide to an ear a noise-cancelling sound effective to substantially cancel at least a portion of the ambient sound.

  • Patent number: 9326085
    Abstract: A transient detector is provided for generating an ambience signal suitable for being emitted via loudspeakers for which there is no special loudspeaker signal to detect a transient period. A synthesis signal generator produces a synthesis signal which fulfills the transient condition on the one hand and the continuity condition for the synthesis signal on the other hand. A signal substituter will then substitute a portion of the examination signal by the synthesis signal to obtain an ambience signal for the surround channels.
