20090148319 | Linear compressor with permanent magnets - This invention provides a compressor with brushless single-phase linear motor, which includes a movable cylinder associated with a permanent magnet array, at least a stationary electromagnetic winding set and a pair of stationary pistons. A partition plate is disposed in the movable cylinder to form a first sub-cylinder and a second sub-cylinder. The front ends of the pair of the stationary pistons are respectively placed in either of two openings of the movable cylinder at its two ends. An alternate current applied to the stationary electromagnetic winding set to generate alternately attracting/repelling forces to the permanent magnet array. The movable cylinder is hence alternately pushed forward and backward. The volumes of the first and second sub-cylinders are changed to compress air in the first sub-cylinder or the second sub-cylinder. | 06-11-2009 |
20110073119 | NEGATIVE PRESSURE ORAL APPARATUS - 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 patentcy 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. The negative pressure will also pull the soft palate into contact with the rear surface of the tongue to create a seal that prevents the air from entering the oral cavity through the nasal airway. | 03-31-2011 |
20110180075 | ADJUSTABLE ORAL INTERFACE AND METHOD TO MAINTAIN UPPER AIRWAY PATENCY - 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 to mouth and prevents disengaging from 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 tissue 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 preventing air from entering the oral cavity from atmosphere.

The connecting channel communicates between the collapsible chamber and a negative source. When a negative pressure environment is generated inside the collapsible chamber via being pumped by the negative pressure source, the non-collapsible structure supports the collapsible chamber so that there are fluid channels formed inside the collapsible chamber. The air inside a user's oral cavity can be pumped out via the fluid channels and the connecting channel. A negative pressure environment is hence formed inside the user's oral cavity. | 02-06-2014 |
