Abstract: A system for processing payments from a customer to a merchant comprises a merchant POS system associated with the merchant, a customer mobile device having a touch sensitive screen; and a payment server. The customer operates the customer mobile device such that a plurality of handwritten calibration signatures input using the touch sensitive screen are stored. A reference signature is generated based on variations between at least two of the plurality of handwritten calibration signatures. The payment server generates a Transaction ID unique to a payment transaction. In response to the generation of the Transaction ID, the customer inputs a handwritten transaction signature using the touch sensitive screen of the customer mobile device. The payment transaction is validated by determining whether the handwritten transaction signature is within at least one tolerance relative to the reference signature; and the payment server generates a payment notice when the payment transaction is validated.

Abstract: A system for processing payments from a customer to a merchant uses a merchant POS system associated with the merchant, a customer mobile device, and a payment server. The payment server generates a Transaction ID unique to a payment transaction. The customer mobile device validates the payment transaction in response to the Transaction ID. The payment server generates a payment notice when the customer mobile device validates the payment transaction. In one case, the merchant POS system presents the Transaction ID to the customer mobile device in preparation for the payment transaction.

The wind power installation also has a working platform which can be fixed to the guide cable for guidance and which can be moved upwardly and downwardly by way of a travel cable. In that way the screw connections of adjacent pylon segment parts can be checked.

Abstract: A microstructured composite component is provided including structures for carrying out fluid processes. A device is provided for producing microstructured composite components. A method provided includes a first step during which a first film is arranged above a second film between first and second mold parts. The first and/or second mold parts have microstructured cavities to be filled. In a second step, the first and second mold parts are heated in at least one region in which they contact one of the films. An excess pressure is then produced between the first film and the second film to force the first and/or second films into the cavities. In a further step, the first and second mold parts are pressed together by a pressing force. Once the first mold part, the second mold part, the first film and the second film are cooled, they form a microstrutured composite component.

Abstract: A method for operating a network having a ring topology, in which a faulty connection between two stations of the network is detected by monitoring carrier signals. This method enables a faulty connection to be quickly detected in a network. Data may be advantageously rerouted in response to the detection.

Abstract: A hair removing apparatus has a hair removing device for at least partially removing hair projecting from a skin, a liquid channel leading to a liquid outlet, a pump for causing liquid displacement through the liquid channel to the liquid outlet, a motor coupled to the hair removing device; a transmission coupled to the motor and to the pump; and a control structure operable between at least a first and a second operating condition for dispensing liquid at different rates. The control structure is arranged for controlling amounts of movement transmitted by the transmission to the pump such that, in the first and second operating conditions, different amounts of movement are transmitted by the transmission to the pump.

Abstract: The invention relates to a device for generating and/or arranging sequences of a fluid sample in a carrier fluid. The invention comprises a microchannel having an inlet, an outlet and a nozzle opening therebetween leading into the microchannel. The invention further relates to a delivery unit, which pumps in the carrier fluid using a feed volume flow and suctions off the carrier fluid using a discharge volume flow. In a sample container, the nozzle opening is in contact with the fluid sample. By means of a control unit, the ratio between feed volume flow and discharge volume flow is varied. The cross-section of the nozzle opening is selected such that no carrier medium exits from the nozzle opening when the feed volume flow equals the discharge volume flow and that a fluid sample enters the nozzle opening when the discharge volume flow is greater than the feed volume flow. The invention further relates to a method for generating and/or arranging sequences of a fluid sample in a carrier fluid.

Abstract: Microwells, which are open on both sides and are arranged two-dimensionally in a microwell matrix (4), are hermetically closed by pressure on both sides using plugs (6) covered with a sealing sheet (11). A layer of elastic material (9), which is arranged between the plug (6) and the sealing sheet (11), guarantees uniform pressure on all the microwells of a microwell matrix (4) which is loosely held by a frame structure (1). Continuous peripheral elevations (2), which protrude in both directions at right angles to the plane of the microwell matrix (4), ensure that the deformable thin layer of elastic material (9) does not escape sideways between the plug (6) and the microwell matrix (4) during the pressing process. A plurality of microwell matrices (4) are held simultaneously by the frame structure (1) and are hermetically closed by a corresponding number of allocated plugs (6), which are fastened to a base plate (7) and a cover plate (8), respectively.

Abstract: Pneumatic spring with at least one control valve inside the pneumatic spring with control positions for feeding, blocking, and discharging compressed air, which valve is actuated by a control element also installed inside the pneumatic valve. The control element acts on one of the two pneumatic spring assemblies which can move relative to each other, namely, either on the outer tube or on the roll tube, where the control element has a working length which is shorter than the stroke length of the pneumatic spring and is pretensioned by a first spring against one of the pneumatic spring assemblies which can move relative to each other. The control element is supported in a floating manner relative to the pneumatic spring assemblies, and a second spring, the force of which is directed against the first spring, co-determines the position of the control element.
