Abstract: An audio device is provided. The audio device comprises a controller and an acoustic transducer. The controller is configured to receive an input audio signal. The controller is further configured to generate, via a loudness detector, a loudness level of a first portion of the input audio signal. The controller is further configured to identify a compression curve of a plurality of compression curves corresponding to a user volume setting. The controller is further configured to adjust, via an audio compressor, a second portion of the input audio signal based on the loudness level and the compression curve to generate an output audio signal. The loudness level is determined according to LUFS model.

Abstract: Systems and methods for calibrating a loudspeaker with a connection to a microphone located at a listening area in a room. The loudspeaker includes self-calibration functions to adjust speaker characteristics according to effects generated by operating the loudspeaker in the room. In one example, the microphone picks up a test signal generated by the loudspeaker and the loudspeaker uses the test signal to determine the loudspeaker frequency response. The frequency response is analyzed below a selected low frequency value for a room mode. The loudspeaker generates parameters for a digital filter to compensate for the room modes. In another example, the loudspeaker may be networked with other speakers to perform calibration functions on all of the loudspeakers in the network.

Abstract: Provided is a mobile health and wellness motivational system in which users specify times and/or locations where they know they will need help with lifestyle challenges. Using the smartphone's clock and geo-fencing technologies, a motivational message arrives at the specified time and/or location. Highly personalized, this system provides motivation in the form of text, photo, video, music or launched text or call; using inspiration, deterrent, tips or distraction at the specified time and/or location that the motivation is needed.

Abstract: A system includes a variable amplifier, a source sound processor, an area sound processor, and an adjustment circuit. The variable amplifier adjusts an audio input signal to generate an audio output signal with an appropriate level so that the audio output signal is audible over noise in a listening area. The source sound processor and the area sound processor may split the audio output signal and a monitoring signal into frequency bands, and may compare these signals band-by-band to find differences that represent time-varying noise in the monitoring signal. These differences may be modified to account for the acoustic response of the listening area and for constant-level background noise in the listening area. The adjustment circuit controls the variable amplifier in response to these differences.

Abstract: An ambient noise compensation system determines an ambient noise level of a listening area. The ambient noise level may be calculated from the differences between a desired audio signal in the listening area, a measured background noise level in the listening area, and measured acoustic characteristics of the listening area. Based on the ambient noise level, the system adjusts a level of the desired audio signal so that it is audible over undesirable noise.

Abstract: A processing rack, such as for electroplating, which minimizes shelf areas of an article during processing of the article and during removal of the article from a processing bath and which allows easy mounting of articles on the rack and demounting of articles from the rack includes a frame and a plurality of article mounting fixtures that are each pivotally mounted on the frame and independently pivotable from a first orientation that facilitates mounting and/or demounting of articles, to a second orientation that is most conducive to producing high quality, substantially defect-free plating.
