Abstract: An antenna array has a signal distribution region and a signal emission region. The signal distribution region has a distribution body made from a dielectric material which converts an information signal, fed into an infeed side thereof, into a spatially distributed signal distribution on an opposite distribution side. The signal emission region has a plurality of signal emission elements distributed over the distribution side. The signal emission elements protrude from the distribution body. At least one signal emission element has a phase shift region, in which a phase shift material with an electrically influenceable permittivity is arranged in the signal emission element. By applying a phase shift voltage between at least one pair of electrodes, the permittivity of the phase shift material is influenced and thereby the propagation speed of an electromagnetic signal in the phase shift region is changed.

Abstract: Method of preparing a biological sample appropriate for use in a subsequent in vitro nucleic acid amplification reaction. A biological sample is combined with an alkaline composition that lyses cells and denatures DNA to create a first liquid composition. The first liquid composition is then mixed with a buffer, a detergent, and a solid support that captures DNA to create a second liquid composition. The buffer, detergent, and solid support can be delivered as components of a single reagent. Captured DNA strands can be used as templates in subsequently performed nucleic acid amplification and detection reactions with improved sensitivity.

Abstract: An antenna device (1) for emitting electromagnetic waves has a waveguide (2), which in turn has two plates (3) made of an electrically conductive material and arranged parallel to one another, between which a dielectric material is arranged. The antenna device (1) has a feed-in device (4), with which electromagnetic waves can be coupled into the waveguide (2), which then propagate along the waveguide (2) and are emitted at an edge (5) of the waveguide (2) at a distance from the feed-in device (4). According to the invention, using a control device of the antenna device (1), the dielectric material can be influenced in such a way that a first region (9) having a first permittivity and at least one second region (10) having a second permittivity are formed, such that the electromagnetic waves coupled into the waveguide (2) propagate preferably through the first region (9) and are emitted in this preferred propagation direction (11).

Abstract: The invention relates to a method for a master-slave communication using the Modbus RTU (Modbus Remote Terminal Unit) standard protocol for resolving an address conflict based on identically set device addresses and for identifying a device connected to the Modbus having a device identification. The addressed device is uniquely identified by means of its device identification, which is transmitted by the request, and a new device address is being transmitted to this uniquely identified device by means of the sent request. The fundamental concept of the present invention is advantageously based on using only the standard way of communication, meaning the standardized master-slave communication, for the assignment of a unique device address on the bus and on using the inherently existing device identification, such as the serial number (see below), for uniquely identifying a device.

Abstract: The disclosure provides dried compositions providing reagents for nucleic acid amplification, which are essentially free of inorganic salts. Lack of inorganic salts increases stability of such compositions and decreases formation of byproducts. Salts required for use of enzymes in the composition are supplied on reconstitution.
