  • Patent number: 10939214
    Abstract: An acoustic transducer for generating electrical signals in response to acoustic signals, comprises a first diaphragm having a first corrugation formed therein. A second diaphragm has a second corrugation formed therein, and is spaced apart from the first diaphragm such that a cavity having a pressure lower than atmospheric pressure is formed therebetween. A back plate is disposed between the first diaphragm and the second diaphragm. One or more posts extend from at least one of the first diaphragm or the second diaphragm towards the other through the back plate. The one or more posts prevent each of the first diaphragm and the second diaphragm from contacting the back plate due to movement of the first diaphragm and/or the second diaphragm towards the back plate. Each of the first corrugation and the second corrugation protrude outwardly from the first diaphragm and the second diaphragm, respectively, away from the back plate.

  • Patent number: 10909999
    Abstract: In some implementations, a computing device can generate personalized music selections to associate with any collections of visual media (e.g., photos and videos) stored on the computing device. A user may prefer particular genres of music and listen to some genres more frequently than others. The computing device can create measures of the user's genre preferences and use these measures to select music that is preferred by the user and music that may be significant or relevant to the particular collection of visual media. The computing device may also determine music that was being played when and where the visual media were being created. The computing device may store the visual media and music items in association with each other. The computing device may generate composite media items that combine the visual media and music items. When the visual media are viewed, the selected music item is also played.

  • Patent number: 10891104
    Abstract: Example techniques relate to prioritizing media content requests. An example implementation involves a computing system receives an explicit request to play back a playlist on one or more playback devices of a media playback system. The computing system causes the playback devices to play back a given audio track of the playlist. While the playback devices are playing back first tracks of the playlist, the computing system receives one or more implicit requests for second audio tracks in the playlist. While the playback devices are playing back the second audio tracks of the playlist, the computing system receives an explicit request to play back audio content on a mobile device. The computing system determines that the request to play back the audio content on the mobile device is a higher priority than the requests for second audio tracks and switches playback from the playback devices to the mobile device.

  • Patent number: 10877725
    Abstract: An image forming apparatus includes a loudspeaker for producing sounds, a controller for performing sound-volume setting for the loudspeaker, and a human-body detection unit for detecting a presence or absence of a human body. The human-body detection unit outputs a value corresponding to a distance between the image forming apparatus and a human body. Upon detecting a human body on a basis of an output value by the human-body detection unit, the controller recognizes, as a first object distance, a distance corresponding to the output value of the human-body detection unit, and performs sound-volume setting for the loudspeaker on a basis of the first object distance.

  • Patent number: 10879792
    Abstract: The disclosure presents a method of operating a switched capacitor voltage converter and a switched capacitor voltage converter, where the switched capacitor voltage converter comprises a power source, a bucket capacitance, an output capacitance with output capacitance terminals to be connected to a load and switches. The power source provides an input voltage and the output capacitance provides an output voltage over the output capacitance terminals. The output voltage is different from the input voltage, i.e higher or lower or of opposite polarity. The switches are configured to provide at least two phases, a bucket capacitance charging phase and a bucket capacitance discharging phase. In case of a voltage up-converter in the bucket capacitance charging phase the bucket capacitance is connected to the power source for charging the bucket capacitance while the bucket capacitance is not connected to the output capacitance.
