With a method for the contactless determination of a thickness of a layer (20) made of electrically-conductive material of a component (17), a sensor composed of a coil form (13) and a coil (14) is positioned in the vicinity of the component (17) to be measured. The method is based on a combination of the principles of induction and eddy current. The thickness of the layer (20) is determined using a plurality of measuring and evaluation steps in which the coil (14) is acted upon with a first alternating current frequency f and its inductance and resistance values are evaluated. The distance between the coil form (13) and, therefore, the coil (14), and the component (17) is derived from the resistance value R of the coil (14) acted upon with alternating current frequency f.

The method is based on a combination of the principles of induction and eddy current. The thickness of the layer (20) is determined using a plurality of measuring and evaluation steps in which the coil (14) is acted upon with a first alternating current frequency f1 and a second alternating current frequency f2, and its change in inductance is evaluated. The distance between the coil form (13) and, therefore, the coil (14), and the component (17) is derived from the inductance value of the coil (14) acted upon with the second alternating current frequency f2.

The invention relates to a lithium secondary cell array in a cylindrical design, comprising a winding mandrel and a winding packet, which contains foil-like coated strips and contacting strips that form the electric cell structure consisting of anode, cathode and separator. The cell array further comprises outer electrical connecting means that comprise pole caps. According to the invention, the winding mandrel consists of an insulating material and has a through-channel extending in the longitudinal axis direction. The winding mandrel is connected to an inner pole cap at each end, the pole caps likewise having a respective through-channel. In addition, one outer pole cap having a through-passage is respectively provided, which surrounds the winding packet circumferentially at leat in the edge region, wherein several radially arranged force-fit connecting means, each acting between the outer and the inner pole cap, are used to fix the winding packet and achieve the electrical contacting between the contacting strips and the outer pole cap.

A technique for performing layer 2 processing is described. In a method implementation of this technique, at least one first RLC SDU is created from one or more first RLC PDUs. It is assumed here that the first RLC SDU belongs to an incomplete RLC SDU set that is to comprise at least one second RLC SDU, and that the second RLC SDU is to be created from at least one second RLC PDU not yet available. In a next step, a first PDCP function is applied to the first RLC SDU to create a data packet. The RLC function is only performed after the second RLC PDU has become available (or after an RLC time-out). Then, after the RLC function has been performed, the data packet is released to a second PDCP function.

A pressure sensing catheter having a pressure sensor and an antenna that is coupled to the pressure sensor, e.g., by a connector, are provided. The pressure sensor can be adapted to measure a pressure surrounding the catheter, and the antenna can be adapted to telemetrically communicate the measured pressure to an external device. In an exemplary embodiment, the antenna, pressure sensor, and/or connector are hermetically sealed, e.g., by the catheter and/or a coating, to prevent the antenna, pressure sensor, and connector from coming into contact with fluid, thereby allowing the catheter to be permanently implanted or otherwise used for long term use. Exemplary methods for manufacturing and using pressure sensing catheters are also provided.

The invention relates to a method for the cohesive connection of a first element (16, 18) to a second element (10), wherein the elements are located one on the other during the connection process and are connected by means of a solder material which is subjected to ultrasonic vibrations during connection by means of a tool (32, 34). In order to allow cohesive connection in an energy-efficient manner, it is proposed that the first element (16, 18) used is one which has through-passage openings (28, 30), that for the purpose of connection the first element and the second element (10) are placed one on the other with through-passage openings open towards the second element, and that molten solder material is located in the through-passage openings during connection and in the through-passage openings the molten solder material is subjected to the ultrasonic vibrations.
