  • Publication number: 20190011639
    Abstract: A reconfigurable spectroscopy system comprises tunable lasers and wavelength lockers to lock to accurate reference wavelengths. Band combiners with differently optimized wavelength ranges multiplex the optical signal over the time domain, to emit a plurality of reference wavelengths for spectroscopy applications. The power requirements are greatly reduced by multiplexing over the time domain in time slots which do not affect sampling and receiving of the spectroscopy data.

  • Patent number: 10147439
    Abstract: A speech-capturing device that can modulate its output audio data volume based on environmental sound conditions at the location of a user speaking to the device. The device detects the sound pressure of a spoken utterance at the device location and determines the distance of the user from the device. The device also detects the sound pressure of noise at the device and uses information about the location of the noise source and user to determine the sound pressure of noise at the location of the talker. The device can then adjust the gain for output audio (such as a spoken response to the utterance) to ensure that the output audio is at a certain desired sound pressure when it reaches the location of the user.

  • Patent number: 10110661
    Abstract: Techniques described herein may be used to expeditiously provide web content to user devices. A web server may provide a first webpage to a user device. Prior to the user device requesting another webpage (e.g., while the user of the user device is viewing the first webpage), the server device may identify a second webpage that the user device is likely to request next and obtain content corresponding to the second webpage. The web server may receive a request for the second webpage, and in response to the request, may provide the second webpage, along with the content, to the user device. The content may include information that is not typically cached by the web server. Additionally, the web server may verify that there are adequate system resources available (e.g., processing capacity, memory capacity, etc.) prior to obtaining the content.
