A method of creating a 3D model of a physical object includes adaptively and iteratively generating a number disparity maps from image data representing a plurality of images of the physical object iteratively captured by a plurality of cameras having electrically adjustable focal lengths by varying at least one of the focal lengths of the plurality of cameras and a distance of the physical object from the plurality of cameras during capture of the images until one of the disparity maps is determined to have a least a threshold level of disparity, and converting the one of the disparity maps into the 3D model.

Provided herein are dry powder formulations comprising epinephrine alone or in combination with at least one enabling agent suitable for nasal application. Also provided are unit dose forms and devices comprising such formulations and methods of using such formulations for the treatment of various conditions including anaphylaxis, anaphylactoid reaction, respiratory conditions, hemodynamic collapse, and for administration during cardiopulmonary arrest and other life-threatening conditions.

A night light may include a night light housing, a light source associated with the housing, a speaker associated with the housing, a controller configured to control operations of the night light, a stand adapted to receive the housing a charge a battery associated with the housing to power the operations of the night light, and a sensor associated with the housing configured to detect when the housing is positioned on the stand or when the housing is not positioned on the stand. The controller may be configured to reduce sound volume output from the speaker, or disable a wireless communication port associated with the housing when the housing is not detected to be positioned on the stand.

A CPAP device for delivering pressurized, humidified breathable gas for a patient includes a flow generator configured to pressurize a flow of breathable gas. The flow generator includes an air outlet and a removable water container configured to humidify the pressurized breathable gas received from the flow generator. The water container includes an air inlet and an air outlet. The CPAP device further includes a first elastomeric face seal configured to sealingly abut against a substantially flat portion of the water container surrounding the water container air inlet, the first elastomeric face seal being located at an intermediate position between the flow generator air outlet and the water container air inlet when the water container is placed into position to pneumatically communicate with the flow generator. In addition, the CPAP device includes a second elastomeric face seal, a portion of which is configured to sealingly abut against a substantially flat external surface portion of the water container surrounding the water container air outlet.

Improvements in fluid volume measurement systems are disclosed for a pneumatically actuated diaphragm pump in general, and a peritoneal dialysis cycler using a pump cassette in particular. Pump fluid volume measurements are based on pressure measurements in a pump control chamber and a reference chamber in a two-chamber model, with different sections of the apparatus being modeled using a combination of adiabatic, isothermal and polytropic processes. Real time or instantaneous fluid flow measurements in a pump chamber of a diaphragm pump are also disclosed, in this case using a one-chamber ideal gas model and using a high speed processor to obtain and process pump control chamber pressures during fluid flow into or out of the pump chamber.

Disclosed is an auto injector for administering a medicament. The auto injector comprising: a housing; a cartridge receiver configured to receive a cartridge assembly comprising a cartridge and a cartridge code feature, the cartridge containing the medicament; a code sensor configured to read the cartridge code feature; a drive module coupled to move a plunger rod; and a processing unit coupled to the code sensor and the drive module. The processing unit being configured to: receive from the code sensor a code signal indicative of the cartridge code feature; control the drive module to move the plunger rod to a first plunger rod position, the first plunger rod position being based on the code signal; receive a trigger event; control the drive module to move the plunger rod to a second plunger rod position following reception of the trigger event.

A supplementary device configured to be releasably attached to a drug delivery device. The supplementary device comprises a housing having a channel configured to slidably receive the drug delivery device; a first alignment feature to ensure a specific alignment of the supplementary device relative to the drug delivery device and restrict rotational movement of the supplementary device around a drug delivery device; and a second alignment feature to prevent sliding movement of the supplementary device relative to the delivery device once attached thereto. The second alignment feature comprises a moveable securing member biased towards the drug delivery device, and a release member operable to move the securing member out of engagement with the drug delivery device.

Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The seal-forming structure may be constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways for sealed delivery of a flow of air at a therapeutic pressure of at least 4 cmH.sub.2O with respect to ambient air pressure throughout the patient's respiratory cycle in use. The positioning and stabilising structure may comprise at least one gas delivery tube to deliver the flow of air to the entrance of a patient's airways via the seal-forming structure. The positioning and stabilising structure may comprise an adjustment mechanism for adjustment of a length of the at least one gas delivery tube to enable the positioning and stabilising structure to fit different size heads.
