  • Patent number: 9387117
    Abstract: This invention provides an oral apparatus and method capable of alleviating or curing snore and obstructive sleep apnea by applying a negative pressure through a mini oral interface to the oral cavity. The mini oral interface creates a secure connection between the interface and mouth or teeth and prevents the interface from falling off. The oral interface also provides fixation between upper and lower lips (or tooth) and prevents opening of patient's mouth during sleeping. The negative pressure pulls the tongue toward upper palate and also pulls the soft palate forward as well. By moving the tongue and the soft palate in a forward direction, the patency of the upper airway near the pharynx is maintained to prevent sleep-disordered breathing. The negative pressure will pull the lips inward to close the mouth ad prevent air from entering the oral cavity from atmosphere.

  • Patent number: 9390720
    Abstract: An encoder performs context-adaptive arithmetic encoding of transform coefficient data. For example, an encoder switches between coding of direct levels of quantized transform coefficient data and run-level coding of run lengths and levels of quantized transform coefficient data. The encoder can determine when to switch between coding modes based on a pre-determined switch point or by counting consecutive coefficients having a predominant value (e.g., zero). A decoder performs corresponding context-adaptive arithmetic decoding.

  • Patent number: 9389364
    Abstract: An optical splitter has a main branch coupled to a number of tributary branches. The main branch includes a light-absorptive core and a light-reflective grating. The absorptive core can absorb light arriving from the tributary branches and transmit light arriving from the main branch to the reflective grating. The reflective grating can reflect light from the main branch back through the absorptive core to the main branch. Light arriving from the tributary branches exchanges mode with light reflected by the reflective grating.

  • Patent number: 9387457
    Abstract: There is provided a water vapor adsorbent for adsorption heat pumps that has high adsorption and desorption performance and high water resistance, such as submersion resistance. The water vapor adsorbent contains a zeolite that contains at least a silicon atom, an aluminum atom, and a phosphorus atom in its framework structure and that has a framework density of 12.0 T/1,000 cubic angstroms or more and 16.0 T/1,000 cubic angstroms or less, wherein the water vapor adsorbent contains a group 11 metal of the periodic table, which constitutes 0.1% to 15% by weight of the zeolite. In the zeolite containing the group 11 metal, an ion of the group 11 metal substitutes for a Bronsted acid site, which promotes a hydrolysis reaction of the zeolite, and decreases the number of Bronsted acid sites of the zeolite, thereby improving the water resistance, such as submersion resistance, of the zeolite.
