Process Engineering Integrated Seat Measurement SMM2 module for vehicle seats or 2 nd generation components for the interior The Berghof SeatMeasModule was developed in order to carry out the entire electrical testing of vehicle seats in the end-of-line tester for the sake of process reliability. The module assumes all requisite resistance measurements incl. protective circuits for measurements on airbags. All the consumers in the seat continue to be supplied with voltage from the module and are switched on and off separately. Each of these supply channels for the seat is equipped with a fast ammeter channel in order to assess the correct functioning of the components in different operating states. Therefore, in principle this measuring module is suitable for testing a multitude of other components in the automotive interiors sector. At present the SMM2 module is in use in final testing lines for car seats (driver and front passenger) and lorry-driver seats. The complexity of the functions in a vehicle seat should on no account be underestimated. Besides the main well-known functions such as seat adjustment, seat heating and the airbag, many more functions can be installed in a vehicle seat. The following are examples of this: massage mats, lordosis support, Philipp Miska automatic child seat recognition (AKSE) in the front passenger seat, bladder mat (weight recognition of front passenger), SBR: seat belt reminder, AV fan (active ventilation), crash-active headrests, ambient lighting, foot room lighting and multi media screens in the headrests. This extremely wide variety of functions requires, for example, current measurements in a broad measurement range (e.g. seat adjustment with 6 seat axes and with currents up to 80 A and sensors in the mA range). The separate evaluation of current values and the analysis of current curves is feasible here. Internally the SMM2 comprises a high-performance power supply unit for currents up to 80 A, an integrated measuring board from our alliance partner, “National Instruments”, and a development of our own for resistance and output measurement which is connected directly to this measuring board. Contact with the vehicle seat is directly via a Harting plug-in connector installed at the rear. All the components are installed in a 19” housing which is supplied with 230 V operating voltage. The SMM2 is connected directly to the PC via the USB interface of the measuring board. Software developed by Berghof can be used to enable all the measuring functions of the SMM2 and calibrate the measuring channels. In the final testing lines already implemented in the production of vehicle seats the SMM2 is often used together with CAN or LIN interfaces for commu- Successful diploma thesis Mr. Philipp Miska did his industrial internship at the Mühlhausen location. Thereafter he was offered the opportunity to also write his diploma thesis at Berghof. The subject of his diploma thesis is “Implementation of an automation system for regular charging of micro processorcontrolled high voltage memories in the hybrid vehicle sector“. In October 2011 Mr. Miska began to implement the task in the context of a project for BMW, the car manufacturing company. He was successful in developing a concept for the cyclical charging of high-volt accumulator batteries (NiMH accumulators) from the automotive sector. A special challenge was vehicle simulation of the internal accumulator controller without which the charging process is impossible. nicating with the control devices in the vehicle seat. Furthermore, additional leak-testing devices are used to test the pneumatic components in a vehicle seat. Peter Deckelmann prozesstechnik@berghof.com For automated charging of the approx. 800 highvolt accumulators it was necessary to connect them to the conveyance system controls. He developed a communication and routing module for this purpose in order to convey the accumulators out of a high rack to the individual charging points. Both modules were integrated successfully into the LabView project and put into operation. The system has meanwhile carried out over 2,000 charging cycles. On 27.04.2012 Mr Miska was awarded the top mark of 1.0 for his diploma thesis and is now working as a project engineer at Berghof in Mühlhausen. At present he is developing a driver to connect endof-line testers for the BMW project. Jürgen Schütze prozesstechnik@berghof.com 4 Berghof News 1/2012
Inauguration celebration in Mühlhausen: Berghof presents the District Administrator with a donation On 15.06.2012 at the celebration to inaugurate the new Berghof company building in Mühlhausen, Thuringia, branch manager Dietmar Sieland surprised District Administrator Harald Zanker with a special kind of gesture. He handed over a cheque for 500,- euros to the District Administrator for the “Childfriendly County” project. Now the money is put to expedient use in the county schools, for example, specifically to procure model construction kits. The District Administrator expressed his appreciation and thanked Dietmar Sieland and the Berghof Group on behalf of the county. Analytics Berghof Analytics undergoes reaccreditation in compliance with DIN EN ISO 17025 Berghof Analytics will be reaccredited in the autumn this year. This extensive DakkS procedure (National German accreditation body) must take place every 5 years. It entails examining the conformity of the entire management system, the relevant specialist departments and competence of the personnel involved. These assessments ensure that the audited processes, services or systems are reliable with regard to their quality and safety, that they correspond to a minimum technical level and comply with the specifications of the relevant standards, directives and laws. This examination according to objective criteria is also known as a conformity assessment. Quality assurance and control with the painstaking documentation that goes with them are a very time-consuming and increasingly central issue in daily routine. In order to meet this high demand it is imperative to have constant monitoring, updates and adaptations to the state-of-the-art at Berghof Analytics. We are required to examine the quality of our work and products on an on-going basis and to stay in line with the specified directives. In order to be able to assess Berghof Analytics exactly the DakkS auditors receive access to all areas of the company. This starts with sampling, includes the various analytical processes and the evaluation of the results through to passing these on to our customers. The application, assessment and receipt of the confirming accreditation certificate is a long, cost- Berghof News 1/2012 From left to right: District Administrator Harald Zanker, Nikolaus Rombach intensive process and can take up to three-quarters of a year. The external costs alone come to around 25,000 euros. All the colleagues are working on it for the sake of continued first-class results and to obtain excellent reaccreditation, as the DAkkS auditors repeatedly confirm to us. Kerstin Reik analytik@berghof.com Successful GMP audit at Berghof Analytics The regular Berghof Analytics GMP audit was carried out on 01.02.212 by the regional authority in Tübingen, Central Office for Pharmacovigilence. The areas: quality management, personnel, rooms, furnishings and equipment as well as documentation and quality control (laboratory organisation, equipment, qualifications, test methods and validation) were all inspected. All areas were inspected and rated by way of random samples in the course of the day. The personnel sector is taken as an example here: The present organisational chart, qualifications of the employees, the distribution of responsibilities at the management level and the deputisation list were all checked. The structure of the training system was examined; and the process for determining the general need for training, the training schedule and the in-house and external trainings was reviewed. Familiarisation plans for new employees were checked and scrutinised. The conclusion for all areas was once again good results without any critical or serious faults and deficits. Only a few miscellaneous faults and deficits were found which are now being processed and eliminated within the framework of a corrective and preventive action plan (CAPA). It goes without saying that the up-to-date certificate is available on our homepage under Contact and Information.
