Hybrid ventilation mask with nasal interface and method for configuring such a mask

A nasal ventilation interface and method for providing nasal ventilation to a patient includes a hybrid face mask, covering only the mouth, coupled with removable nasal inserts extending from the upper surface of the mask. The nasal interface has modular, removable, and disposable nasal pillows connecting the upper surface of the mouth-portion of the mask to the user's nares. Each part of the hybrid mask is modular and can be formed in various shapes and sizes. The ventilation interface has differing gas line entry ports and can be shallow with a relatively deep soft facial interface or deep with a relatively shallow facial interface. In either case, the upper surface receives the nasal interface. The upper surface can have a removable ceiling in which is defined a nasal interface connector. The nasal interface can be integral with a removable ceiling. The entire hybrid mask can be made in one piece.

Image reject mixer, circuit, and method for image rejection

To reduce the impact of image frequencies generated by mixing an incident carrier signal down to a relatively low intermediate frequency signal used in subsequent signal processing, a mixing frequency is selected such that the generated intermediate frequency signal has a frequency offset relative to DC that is substantially that of a single channel spacing between frequency adjacent incident carrier signals, as shown in FIG. 2. Image rejection is further improved through the integration of a current-driven polyphase filter (36) directly between an input stage (Q1 to Q4) and a mixer stage (Q5 to Q12) of an image reject mixer (FIG. 4) such as to mitigate quadrature divergence between separate in-phase and quadrature paths within the image reject mixer.

Dry powder inhalers, related blister devices, and associated methods of dispensing dry powder substances and fabricating blister packages

The present invention includes dry powder inhalers and associated multi-dose dry powder packages for holding inhalant formulated dry powder substances and associated fabrication and dispensing methods. The multi-dose package can include a platform body comprising at least one thin piezoelectric polymer material layer defining at least a portion of a plurality of spatially separated discrete elongate dry powder channels having an associated length, width and height; and a metallic material attached to selected portions of the piezoelectric polymer material including each of the regions corresponding to the elongate dry powder channels to, in operation, define active energy releasing vibratory channels. In operation, the elongate channels can be selectively individually activated to vibrate upon exposure to an electrical input.
The dry powder inhaler includes an elongate body having opposing first and second outer primary surfaces with a cavity therebetween and having opposing top and bottom end portions and a multi-dose sealed blister package holding a plurality of discrete meted doses of a dry powder inhalable product located in the cavity of the elongate body. The inhaler also includes an inhalation port formed in the bottom end portion of the elongate body, the inhalation port configured to be in fluid communication with at least one of the discrete meted doses during use and a cover member that is pivotably attached to the elongate body so that it remains attached to the body during normal operational periods of use and moves to a first closed position to overlie the inhalation port at the bottom end portion of the body during periods of non-use and moves to a second open position away from the inhalation port during periods of use to allow a user to access the inhalation port.
