Title: Medication delivery device
Inventor: HARMS MICHAEL
IPC: A61M5/315
Filed: 2009-04-17
Abstract: The application refers to a medication delivery device (1) comprising: a medication receptacle (6), a dosing mecha-nism comprising: a piston rod (17) a drive device (19), a dose setting member (27) and a dose limiting member (28) which pre-vents the setting of a dose of medication which exceeds an amount of medication contained in the medication receptacle (6) and a housing (3). The dose limiting member (28) is designed for axial movement in a proximal direction with respect to the piston rod (17) during dose setting and comprises a first stop element (35) and the piston rod (17) comprises a second stop element (36). The first and second stop elements (35, 35) stop an axial movement of the dose limiting member (28) in the proximal direction with re-spect to the piston rod (17) when the first and second stop elements (35, 36) catch, thereby limiting a movement of the dose set-ting member (27) for increasing a set dose of medication to be delivered.  The dose limiting member (28) and the piston rod (17) only interact directly, when the first and second stop elements (35, 36) catch.

Title: Combined air conditioning and water generating system
Inventor: FAKIEH ABDULRAHMAN ABDULKADER MOHAMMAD
IPC: F24F13/30
Filed: 2011-03-28
Abstract: An Air conditioning and potable water generating system in which a cooling element condenses water from atmospheric air is operable two switch between an air conditioning mode, in which cooled atmospheric air from which water has been extracted is supplied to a building's interior environment, and a water generating mode, in which communication of such supply air into the building interior is closed off. The system can thus be operated to collect water regardless of whether cooling of the building interior is required at a particular point in time. Use of the same cooling element in each mode provides and use of return air from the building to mix with incoming fresh air and cool the heat dissipating element of the cooling system make for efficient operation. Controls of the system are operable to change a mixture ratio of the fresh atmospheric air and circulating return air.

IPC: H05G1/52
Filed: 2009-11-23
Abstract: An x-ray tube is described that includes components for increasing x-ray image clarity in the presence of a moving x-ray source by modifying focal spot characteristics, including focal spot size and focal spot position, tn a first arrangement a static focal spot is moved in a direction contrary to the movement of the x-ray source so that an effective focal spot position is essentially fixed in space relative to one of the imaged object and/or detector during a tomosynthesis exposure. In a second arrangement, the size of the static focal spot is increased, and the resulting increase in tube current reduces the exposure time and concomitant blur effect. The methods may be used alone or in combination; for example an x-ray tube with a larger, moveable static focal spot will result in a system that fully utilizes the x-ray tube generator, provides a high quality image with reduced blur and, due to the decrease in exposure time, may scan the patient more quickly.

IPC: A61F13/26
Filed: 2010-01-28
Abstract: A method of injection molding produces a microcellular material. In this method, a polymer is melted and blended with a supercritical fluid to produce a single-phase polymer-gas solution.  This solution is injected through a nozzle and into a mold. When injected through the nozzle, gas in the solution (from the supercritical fluid) emerges from the polymer, which then solidifies. In emerging from the solution, the gas causes the nucleation of cells that result in a microcellular structure. A foam material comprises a polymer having a microcellular structure formed by the nucleation of micro-cells. The micro-cells are formed by the dispersing of a supercritical fluid in a liquid solution of the polymer when the polymer is subjected to a pressure drop. A feminine hygiene device is fabricated from a foamed polymer.
