Abstract: A droplet delivery device includes a housing with a mouthpiece port or outlet from a nasal device for releasing fluid droplets, a fluid reservoir, and an ejector bracket having a membrane positioned between a mesh with a plurality of openings and a vibrating member that is coupled to an electronic transducer, such as an ultrasonic transducer. The transducer vibrates the vibrating member which causes the membrane to push fluid supplied by the reservoir through the mesh to generate droplets in an ejected stream released through the outlet.

Abstract: The present invention relates to touch-sensor detector systems and methods incorporating an interpolated variable impedance touch sensor array and specifically to such systems and methods for force-aware interaction with handheld display devices on one or more surfaces of the device. An exemplary embodiment includes a method for receiving a flexing gesture formed on a sensor panel of the handheld device including determining two or more pressure inputs at the sensor panel and determining a relative pressure between the two or more pressure inputs. The method further includes correlating the relative pressure inputs to the flexing gesture, associating the flexing gesture with a UI element and providing an input to the UI element based on the gesture and the relative pressure between the two or more pressure inputs.

Abstract: Disclosed is a method for treating actinic keratosis of tissue of a patient, the method including contacting non-thermal, atmospheric pressure plasma over areas of the tissue having actinic keratosis for a time and at treatment conditions effective to give rise to an at least partial amelioration of the keratosis.

Abstract: A furnace including a combustion chamber for burning fuel can have increased fuel burning efficiency, increased heating efficiency, and decreased harmful emissions of combustion byproducts. A combustion air delivery system delivers primary and secondary combustion air to the combustion chamber. Primary and secondary combustion air may be delivered at amounts that increase burning efficiency. An amount of secondary combustion air can be controlled by a valve system. A heat transfer device efficiently transfers heat from products of combustion for heating an enclosed space.
