Abstract: A soldering nozzle (100) for selectively soldering assemblies by means of molten solder supplied through a soldering nozzle (100) from a solder bath. The soldering nozzle (100) is designed as a deep-drawn part. A method for the production of a soldering nozzle (100) is specified as well, including the provision of a blank (401); the drawing of the blank (401) through at least one female die (411, 421) by means of at least one male die (413, 422, 431) to produce an oblong shape (439) of locally annular or substantially annular cross-section, with a first end (436) corresponding to an action point of the male die (413, 422, 431) and a second end (437) corresponding to an introduction cross-section of the male die (413, 422, 431), the cross-section preferably increasing from the first end (436) towards the second end (437); and the formation of an opening (446) at the tip end (436).

Abstract: The invention relates to a presence status determination system and a computer implemented method to determine the presence status of a first user registered in a network and to communicate this presence status to a second user, who would like to make contact with the first user. An input device for a presence status determination device records a predetermined first presence status component determined by the first user and forwards the first presence status component to the presence status determination device (20). A contact person registration device records the identity of the second user and reports the identity to a relationship determination device. The relationship determination device determines, with the aid of a computer, a second presence status component, which considers the social proximity between the first user and the second user.

Abstract: A device (1) for use in optical spectroscopy and a method for its manufacture are described. The device includes at least one light source (8) and at least one spectrometer (3) fabricated integratively, the optical components of the at least one spectrometer (3) being optical microcomponents (11,13,16,19,20,21) which are mounted integratively on the top and/or bottom side (9,12) of a substrate board (2). In the method according to the present invention, at least one light source (8) is mounted on a substrate board (2), and at least one spectrometer (3) is produced monolithically in a three-dimensional integration on the substrate board (2). In this context, the spectrometer (3) that is produced according to the method is assembled from optical microcomponents (11,13,16,19,20,21).

Abstract: In order to determine the spatial position of a device (D), the device receives position data relating to a plurality of transmitters (T1, . . . , Tn) in the area surrounding the device, each of which transmitters emits its own position data in the form of radio signals (PS1, . . . , PS j). The device uses the received position data relating to at least some of these transmitters to determine its own position. The transmitters are parts of a plurality of second communication devices (T1, . . . , Tn) each having at least two radio interfaces (RI1, RI2) of a first type (RI1) and of a second type (RI2) in a network (N) of a plurality of first communication devices (AP1, . . . , APm) each having at least one radio interface of the second type (RI2), wherein the network is switched via the radio interfaces of the second type (RI2). At least some of the first and second communication devices are set up to emit first signals (BS1, . . . , BSk) via the radio interfaces of the second type (RI2).

Abstract: The invention relates to a device, to a set of tubes and to a method for carrying a gas or a liquid to a surface through a tube, especially in order to produce gas mixtures or to treat the surface using gas lithography. The tube or in the case of a set, each tube of the set has an inlet opening and an outlet opening. A shaft is allocated to each tube, this shaft being arranged in the axial direction of the tube and being displaceable in its longitudinal direction in relation to the tube, from a first position to a second position and vice versa. Each shaft bears a blocking body which blocks or unblocks the outlet when the shaft is in the first or second position. A gas reservoir and a supply line by which means the inside of the gas reservoir is connection to the inlet opening of each tube are also allocated to each tube, so that gas is able to flow from the insider of the gas reservoir into the tube.
