  • Patent number: 10461710
    Abstract: Disclosed herein are embodiments for adjusting playback volume in a media playback system that utilizes a maximum volume feature. In one embodiment, when a playback device receives an instruction to change its playback volume to a requested volume level, the playback device will not necessarily set its playback volume state variable to the requested volume level, but rather will calculate a new (typically lower) alternate volume level based on the maximum volume state variable and instead set its playback volume state variable to that alternate volume level. Moreover, when a playback device shares certain of its state variables among the other devices of the media playback system, the playback device will not necessarily share its actual playback volume state variable, but rather will calculate a new (typically higher) representative volume level and instead share that representative volume level.

  • Patent number: 9072817
    Abstract: The present invention relates to a bone-repair composition comprising a micro-pulverized demineralized bone matrix; a nonmicro-pulverized demineralized bone matrix; and a hydrating material. The bone-repair composition of the present invention provides easier injectability and shape-maintenance (handling), and exhibits excellent bone-repairing effects due to a large surface area of the micro-pulverized demineralized bone matrix and an early release of the bone growth factors, compared with conventional compositions comprising the nonmicro-pulverized demineralized bone matrix alone. It also has an advantage of being biocompatible and harmless to the human body because there is no use of synthetic materials.
