20110061526 | Diaphragm Pump - A diaphragm pump includes a pump chamber having an inlet opening and an outlet opening. A passive silicon check valve is provided at the inlet opening, and a passive silicon check valve is provided at the outlet opening. The diaphragm pump further includes a metallic pump diaphragm that adjoins the pump chamber. | 03-17-2011 |
20110224603 | DEVICE AND METHOD FOR DETERMINING AT LEAST ONE FLOW PARAMETER - A device for detecting at least one flow parameter includes a fluidic series connection of a first flow restriction, a first measurement area, a second flow restriction, and a second measurement area. A first sensor is provided for detecting a quantitative first measure of a pressure existing in the first measurement area. A second sensor is provided for detecting a quantitative second measure of a pressure existing in the second measurement area. An evaluator is provided which is configured to determine, while using the measures detected by the first and second sensors, a flow rate of a fluid flowing through the series connection, and/or to determine whether there is an occlusion of the first flow restriction, of the second flow restriction, or of a fluid area adjoining the second measurement area. | 09-15-2011 |
20110280755 | PUMP, PUMP ARRANGEMENT AND PUMP MODULE - A pump has an inlet opening, an outlet opening, a pump diaphragm comprising an opening, provided with a passive check valve, through the pump diaphragm, and an actuator configured to move the pump diaphragm between a first position and a second position. The passive check valve is configured such that a movement from the first position in the direction toward the second position has a closing effect, and that a movement from the second position in the direction toward the first position has an opening effect, so that a pumping cycle wherein the pump diaphragm is moved from the first to the second positions, and back, causes a net flow from the inlet opening to the outlet opening. | 11-17-2011 |
20120063928 | Pump Having a Filter Arrangement - A pump for pumping a medium from a suction side to a pressure side includes a filter arrangement. The filter arrangement includes an inflow path, a first outflow path, and a second outflow path. A hydrophobic membrane filter is arranged between the inflow path and the first outflow path. A hydrophilic membrane filter is arranged between the inflow path and the second outflow path. At least one section of the hydrophobic membrane filter and one section of the hydrophilic membrane filter are located opposite each other at a distance of no more than 1 mm so that a gas bubble that moves along with a medium flowing in the inflow path comes into contact with the hydrophobic membrane filter during the movement. The first and second outflow paths of the filter arrangement are connected to the suction side of the pump. | 03-15-2012 |
20130055889 | METHOD FOR MANUFACTURING A BENDING TRANSDUCER, A MICRO PUMP AND A MICRO VALVE, MICRO PUMP AND MICRO VALVE - A method of manufacturing a bending transducer having a drive element and a membrane includes providing the membrane and the drive element and applying a production signal to the drive element during a bonding of the drive element to the membrane such that the drive element is pre-stressed after the bonding, wherein the production signal is of a same kind as an operation signal to operate the bending transducer. | 03-07-2013 |
20130068325 | VALVE, LAYER STRUCTURE COMPRISING A FIRST AND A SECOND VALVE, MICROPUMP AND METHOD OF PRODUCING A VALVE - A valve, including a valve opening and a valve plate arranged to seal the valve opening in a closed state by means of compressing a sealing structure is provided, wherein the sealing structure includes an uncompressed dimension in a compression direction of less than 100 μm. | 03-21-2013 |
20140069214 | TEST STATION AND METHOD FOR TESTING FLUIDIC COMPONENTS - A test station for testing at least one of fluidic component arranged on a substrate, each fluidic component having a fluidic port, comprises a carrier device for holding the substrate with the at least one fluidic component, a connecting device for fluidically connecting the fluidic port of the at least one fluidic component located in a testing position to a first adapter element of the connecting device, and a displacement device configured to displace the substrate and the connecting device relative to each other, and to bring the substrate into the testing position. | 03-13-2014 |
20140069420 | CONTROLLABLE FLUID SAMPLE DISPENSER AND METHODS USING THE SAME - A fluid sample dispenser includes a microdosing device for outputting, during an activation state, a fluid sample at a fluid sample outlet to the environment, wherein the microdosing device is placeable adjacent to a person's nose so that a distance between the outlet of the microdosing device and a nostril of the person's nose is within a predefined range, and a microdosing driver unit for adjusting a dosing rate of the scent sample output at the scent sample outlet by selectively activating the microdosing device. | 03-13-2014 |
