Abstract: A method of making a prepackaged, combustible unit of a plant based material for use in an inhalation system, metered dose inhaler, or dry powder inhaler. The method includes creating and shaping a combustible material packaging by processing leaves or plant fibers into a fibrous sheet, steaming the fibrous sheet, and using a female mold and a corresponding male mold to shape the combustible material packaging. The method further discloses filling pockets disposed within the combustible material packaging with the combustible material and sealing the combustible material packaging around the combustible material to create a prepackaged, combustible unit. Additional embodiments include various inhalation devices, inhalation systems, kits having instruction as to using the inhalation device, and methods of making the prepackaged combustible unit, and methods for using the inhalation devices.

Abstract: A launch device for a vehicle transmission including a housing, an impeller, a turbine, and first and second clutches with first and second pistons, respectively. The first and second pistons are sealingly engaged with one another. The first clutch releaseably engages the impeller with the housing and the second clutch releaseably engages the turbine with the housing. In an example embodiment, the first clutch is disposed radially outside of the second clutch. In an example embodiment, the first clutch is engaged by a first pressure, and the second clutch is engaged by a second pressure greater than the first pressure.

Abstract: An apparatus and system are disclosed for in situ measurement of downhole fluid flow using Doppler techniques. First, a baseline speed of sound is established as close to the desired measurement point as possible. This speed of sound measurement is then used in Doppler calculations for determining flow velocities based from induced Doppler shift resulting from fluid flow. A heterodyne receiver arrangement is preferably used for processing so that the flow direction can be determined and the detection sensitivity for low flow velocities can be enhanced. From in situ measurements, well kicks may be spotted and dealt with in real-time. In addition, current theoretical models of rheological properties may be verified and expounded upon using in situ downhole measurement techniques. Furthermore, the velocity measurements described herein can be used to recognize downhole lost circulation and/or gas/water/oil influxes as early as possible, even when the mud recirculation pumps are turned off.
