Abstract: Dry powder inhalers include: (a) a first generally planar spiral travel path in an inhaler body, wherein the first spiral travel path has a plurality of adjacent curvilinear channels forming lanes with upstanding sidewalls, including an inner lane and an outer lane; and (b) a plurality of discrete sealed microcartridges with substantially rigid bodies disposed in the first travel path, each comprising a pre-metered (typically dose) amount of dry powder, the microcartridges being configured to slidably advance along the first travel path toward an inhalation chamber that merges into an inhalation output port. In operation, at least one microcartridge is held in the inhalation chamber to release the dry powder therein during inhalation.

Abstract: A collapsible housing including a first housing having a magnetic member (108) carried by the first housing (110). A slide enabling member (104) is rotatably coupled to the first housing by a hinge (102), the slide enabling member rotating about a rotation axis (106) of the hinge and, the slide enabling member extending radially from the rotation axis. A second housing (120) is slideably coupled to the slide enabling member such that the second housing slides along the slide enabling member. The housing further includes an engaging member (112) carried by the second housing and selectively engageable to the magnetic member. A first urging member (118) is coupled between the first housing and the slide enabling member, the first urging member urging the slide enabling member to rotate about the rotation axis relative to the first housing.

Abstract: The present invention provides a mechanism and method for rotating at least a first and second housing elements (120, 220) of a device (100) with respect to one another. The first and second housing elements (120, 220) have a common axis of rotation (270), which is substantially perpendicular to a front surface of the device (100). The mechanism includes a first transport (302), a second transport (304), a tension device (306), and an engagement member (400). The first and second transports (302, 304) selectively engage contact elements (308, 310) of the first and second housing elements (120, 220) and selectively travel about a ring path as the first and second housings rotate relative to one another.

Abstract: An acoustic chamber (220, 222) and port (104, 202) for an electronic device are disclosed. A loudspeaker (204, 206) is coupled to port through the acoustic chamber. A port (104, 202) passes at least light from the chamber. A light element (224, 226) is carried within the acoustic chamber to emit light from the light port.

Abstract: An electronic device. The electronic device can include a frame including at least one aperture, the frame having a first side and a second side, an audio source located on the second side of the frame, and a front housing including a lightguide. The front housing can include a front first side and a back second side opposite the first front side, the back second side facing the first side of the frame. The front housing and the frame can create an acoustic chamber for the audio source.
