A method for generating a key in a network. The network includes at least one first user and one second user having a secured communication link to one another, and a third user, to which a secured communication link is to be established. The first user and the third user each generate a first partial value sequence from properties of the transmission channel between the first user and the third user. The second user and the third user each generate a second partial value sequence from properties of the transmission channel between the second user and the third user. In a secured part of the network, which includes at least the first and the second user, but not the third user, the key is ascertained from at least the first partial value sequence of the first user and the second partial value sequence of the second user. The key is also generated in the third user from at least the first partial value sequence and the second partial value sequence.

A manipulator-guided folding (hemming) tool (1) includes a frame (9) having a preferably roller-shaped folding element (15, 16, 17, 17′) and a connection (10) for connecting to a manipulator (2), and a detecting device (34) for the loads that occur during folding. The detecting device (34) has an indicator (38) for the loads, which indicator is arranged on the folding tool (1). The indicator is preferably designed as an optical indicator and is arranged in a tool area that is visible during folding.

A microfluidic device having a sample inlet for receiving a sample of biological material having nucleic acid sequences, a polymerase chain reaction (PCR) section with a PCR microchannel for thermally cycling the sample to amplify the nucleic acid sequences, the PCR microchannel defining a flow-path for the sample such that flow of the sample along the PCR microchannel is driven by capillary action, and, the PCR microchannel has a cross sectional area transverse to the flow less than 100,000 square microns.

A microfluidic device having a supporting substrate, a sample inlet for receiving a sample of biological material having nucleic acid sequences, a microsystems technology (MST) layer having a polymerase chain reaction (PCR) section for amplifying the nucleic acid sequences, the PCR section having at least one heater for thermally cycling the nucleic acid sequences through a denaturation phase, an annealing phase and a primer extension phase, and, CMOS circuitry between the MST layer and the supporting substrate, the CMOS circuitry being connected to the at least one heater for operative control of the at least one heater during the thermal cycling.

Hunting blinds include a frame comprising two rod attachment structures at opposing longitudinal sides and a plurality of support attachment structures extending between and coupled to the two rod attachment structures. A rod is coupled to each of the two rod attachment structures, and a support member rod is coupled to each of the support attachment structures. Methods of using hunting blinds and methods of making hunting blinds are also disclosed.

A microfluidic device for dialysis of biological material, the microfluidic device having a sample inlet for receiving a sample of biological material that has constituents of different sizes, a dialysis section for separating smaller constituents from larger constituents, the smaller constituents being smaller than a predetermined size threshold, and the larger constituents being larger than the predetermined size threshold, and, a microsystems technology (MST) layer for separately processing the smaller constituents and/or the larger constituents.

The invention concerns a portable device for transmitting electromagnetic waves. It is capable, when arranged at a surface, of transmitting waves having a power flux density of at least 0.5 milliwatts per square centimeter of surface area and a frequency value of between 3 and 120 gigahertz. The device is, moreover, capable of simultaneously exposing at least 2.5 square centimeters of the surface to the waves.

A microfluidic device for processing a fluid sample, the microfluidic device having a reservoir for containing a reagent, and, a surface tension valve having an aperture configured to pin a meniscus of the reagent such that the meniscus retains the reagent in the reagent reservoir until contact with the fluid sample removes the meniscus such that the reagent flows out of the reagent reservoir.
