| 20090250058 | Inhalation System and Delivery Device for the Administration of a Drug in the Form of Dry Powder - The administration of at least one drug in the form of dry powder by inhalation through an air flow path may be accomplished by an inhalation system including a delivery device having a mouthpiece through which the powder is inhaled. The inhalation system includes a dose cassette defining at least one drug cavity containing dry powder of a dose to be delivered and being sealed by a lid.

| 20100051027 | Entraining Powder In An Airflow - A device for inhalation of at least one air stream carrying a dose of medicament powder. The device comprises a powder-containing cavity which opens into a flow passage. The flow passage is arranged to direct an inhalation air flow across the cavity opening. A circulating flow is thereby induced in the cavity by the phenomenon of shear driven cavity flow. Powder is entrained in the circulating flow and deaggregated before exiting the cavity and becoming entrained in the flow of air along the flow passage. | 03-04-2010 |
| 20100307491 | Inhaler Comprising A Base Having At Least One Sealed Cavity Containing Medicament - An inhaler which comprises a base having at least one sealed cavity containing medicament and a foil portion comprising two sides, one side being attached to the base for sealing the medicament within the cavity. A separating element is attached to the other side of the foil portion for separating the foil portion from the cavity, the separating element having a first end and an opposite second end, wherein the separating element is movable to an intermediate tilted position in which said first end is moved-away from the cavity. The separating element is further movable from the intermediate tilted position to a removed position in which also said second end is moved-away from the cavity so that the foil portion is removed from the cavity which is thereby uncovered so that medicament contained therein is enabled to become entrained in a fluid flow. | 12-09-2010 |
| 20100326440 | Inhaler Comprising A Base Having A Plurality Of Medicament Containing Sealed Cavities - An inhaler which comprises a base having a plurality of consecutive sealed cavities containing medicament. Foil portions are on one side attached to the base for sealing the medicament within respective associated cavities. A plurality of separating elements are attached to the other side of the foil portions, each separating element being associated with a respective cavity for separating a foil portion from that cavity. Each separating element can be moved-away from its associated cavity so that the sealing foil portion is separated from the cavity which is thereby uncovered so that medicament contained therein is enabled to become entrained in a fluid flow, and then returned with the attached foil portion to cover its associated cavity. A method of operating an inhaler is also disclosed. | 12-30-2010 |
| 20110083667 | DISPENSER AND METHOD FOR ENTRAINING POWDER IN AN AIRFLOW 537 - The invention relates to a method for entraining in an airflow a medicament powder contained in a cavity having a cavity opening. Large airflow vortices are provided, for instance, by means of an obstacle in a flow passage. The airflow with large vortices is arranged to by-pass the cavity opening, thereby generating an eddy in the cavity which contributes to entraining the powder in said airflow. The invention also relates to a medical dispenser, for instance an inhaler, in which said method may be performed. | 04-14-2011 |
| 20110226243 | DEVICE AND METHOD FOR DEAGGREGATING POWDER 854 - The present disclosure relates to a device for inhalation of at least one air stream carrying a dose of medicament powder. The device comprises a flow passage passing a powder-containing cavity. A part of said flow passage propagates along a generally flat surface region. The flat surface region comprises a cavity opening into said powder-containing cavity. The passing of an air stream along said flat surface region and outside said cavity generates an eddy in the cavity and the generated eddy contributes to deaggregation of the powder in said cavity and emptying of the powder from said cavity. Furthermore, the present disclosure relates to the use of a shear driven cavity principle on such a device and a method of releasing medicament powder. | 09-22-2011 |

| 20120125330 | INHALATION DEVICE AND METHOD OF DISPENSING MEDICAMENT - The present invention relates to an inhaler, comprising a base having at least one air-tight, foil-sealed cavity containing medicament. An actuator is engagable with a separating element attached to the foil, the actuator having an energized position in which it is biased towards an unloaded position so as to cause the separating element and attached foil to be moved away from the cavity. A latch has a first position, in which it latches the actuator in said energized position, wherein the latch is at least partly arranged in a flow path such that an inhalation flow through the flow path affects the latch to move from the first position to the second position. The invention also relates to a method of dispensing a medicament from a sealed cavity inside an inhaler. | 05-24-2012 |

| 20090132941 | CREATION AND USE OF DIGITAL MAPS - Techniques described herein allow a user to automatically associate an object with a location of the user and/or the object. This object and associated location may then be transferred to an entity for publishing the object and location on a map. For example, a user may capture a digital picture or video on a device and, in response, may automatically transmit the picture or video and corresponding location data for publishing to a map that is associated with the user. The described techniques also allow a user to create a journal that is associated with an annotated map. For instance, the user may create a journal having one or more portions that are associated with one or more portions of an annotated map. As a user consumes (e.g., reads, views, listens, etc.) the created journal, the view of the map or the displayed annotations may correspondingly change. Finally, the described techniques allow for creation of multiple overlays on a digital map. That is, these tools may allow each of multiple users to create an overlay, comprising one or more annotations, onto a digital map. These tools may then allow consuming users to choose whether to view all, some, or none of these user-created overlays. | 05-21-2009 |
