  For an internationally leading machine manufacturer, we developed a high-performance software solution for a complex production machine.
  The machine has a transport unit that guides products through various modules integrated into the system. These modules perform different tasks such as modification, marking or high-precision quality analysis of the products.

  The devices used include lasers, scanners, cameras, label printers and chip programming units. Each of these devices is controlled by its own software module, which carries out specific functions, checks and sequences depending on the product type and production speed.

  Communication between the machine and the devices takes place via common industrial interfaces such as PLC (Beckhoff TwinCAT), TCP/IP and other established protocols.
  A central control module coordinates all processes, ensures optimal interaction between the individual components and guarantees a smooth production flow.

  The entire software runs in real time on a dedicated real-time operating system. A connected database is integrated for configuration and data management.
  An intuitive GUI on the central terminal gives the operator insight at all times into the status of the product, potential errors and all relevant configuration options.

  We took on the complete software development process for the customer, from requirements management through software architecture, implementation and deployment to testing and quality assurance.
  The project ran for around a year and was carried out by an interdisciplinary team of six experienced developers.

  We are delighted to introduce our new research project: HIRAC - Hardware Independent Robotic Assistance Controller. Cadida Software, in cooperation with Offenburg University of Applied Sciences, has launched this exciting project to bring lasting improvements to the quality of life of people with full-body paralysis and people with locked-in syndrome.
  
  

  People with full-body paralysis and patients with locked-in syndrome face considerable challenges in everyday life. Even basic actions such as picking up a glass of water are often beyond their reach. Their limited ability to speak also makes it difficult for them to use voice-controlled devices. The HIRAC project aims to help these people while also easing the burden on care staff.

  The vision is to develop an assistance system consisting of artificial intelligence (AI), eye-tracking control of the wheelchair, a gripper arm on the wheelchair and speech output. This system is intended to enable people with full-body paralysis to carry out everyday tasks independently. In particular, it is crucial to develop a component that is compatible with commercially available wheelchairs, robotic arms, gripping mechanisms and eye-tracking glasses and can control them. This component is called HIRAC (Hardware Independent Robotic Assistance Controller).

  Our task is to develop this hardware-independent middleware, which can solve the robotic gripping tasks. This middleware integrates a powerful AI that brings together and controls eye-tracking control, image processing, sensor feedback and object manipulation. 

  We are proud to be able to work on this pioneering project with the support of the Central Innovation Programme for SMEs (ZIM). This funding enables us to drive forward the development and implementation of HIRAC at full strength.

  We are confident that HIRAC will make a significant contribution to improving the quality of life of people with full-body paralysis and people with locked-in syndrome. Read the detailed article on this research project here.

• read more

  People with neurological disorders such as Parkinson's disease or multiple sclerosis benefit from regular and precise assessment of their motor symptoms to evaluate the course of the disease and adjust their therapy. We bring standard clinical assessments into patients' homes by providing special software. The software automatically carries out a wide range of motor assessments, visually analyses whole-body movement in 3D and then provides the treating doctor or therapist with diagnostic parameters.

  The customer is about to enter the market with an existing telemedicine solution in C#/WPF. Further requirements of the healthcare market and of the software prompted it to quickly buy in additional development and project management capacity from us.

  Because of the regulatory requirements in the medical context, our staff were trained in the customer's processes and closely involved in them. The prior knowledge of medical software development and sensor technology that our staff brought with them was a great advantage here.

  Despite the special requirements, development work on this project, which is very interesting both technically and in terms of content, is going very well, so that this innovative telemedicine solution can soon be made available to many patients.

  At the end of 2020, Cadida was awarded the contract for the project. Development was planned to run for 3 years and was carried out in cooperation with 5 consortium partners: a research foundation, a university and 3 industrial companies.

  With this device, samples can be tested for the presence of specific DNA sequences much faster, more easily and with greater complexity. In practice, for example, blood samples can be tested for the presence of cancer DNA, or food samples such as maize for the presence of genetically modified components (GMOs).

  In detail, our tasks comprised the computer-aided analysis and visualisation of the data, creating the user interface, camera and LED control, image acquisition, image analysis and presentation of results.

  Cadida was also responsible for the design and implementation of the software architecture and for the data models and interfaces. We developed user stories (use cases) and provided automated tests to verify them, ensuring that the requirements were met in detail.

  This exciting project started in February 2021.

Customer: Measuring instrument manufacturer
Technologies: LabVIEW, LabVIEW-UNITTEST

• read more

  For a measuring instrument manufacturer, we analysed its LabVIEW development and carried out unit tests to ensure quality assurance.

  The LabVIEW program has grown over many years and is correspondingly extensive and deeply nested. The project began with an analysis of the LabVIEW VIs and an investigation of possible weak points. For this, our team developed unit tests with LabVIEW-UNITTEST. These are run automatically to assure quality and to check code changes to the LabVIEW VIs. In particular, risk areas were identified and memory leaks located in order to move repairs forward.

  In this way, our customer was able to make sure that the continuous operation of measurements is guaranteed.

Programming of LabVIEW interfaces for thermal imaging cameras (parameter exchange, real-time streaming and control of thermography cameras) with LabVIEW. Development of block diagrams and the user interface in LabVIEW, which allow the end user comprehensive control of the camera and support them in research and development.

Customer: Large international measuring instrument manufacturer
Technologies: LabVIEW, C++, CMake, Google Unit-Test, Visual Studio and TFS

• read more

  An international public limited company for measuring instruments needed our know-how to connect its thermal imaging cameras to LabVIEW. It was looking for a high-quality solution with which it could connect its devices to the graphical programming system and obtain licensing from National Instruments, the manufacturer of LabVIEW.

  The project started with consulting on LabVIEW, device drivers, interfaces and licensing. We carried out the creation of the software architecture, the programming and extensive unit and system tests, and regularly demonstrated the progress.

  The LabVIEW device driver for the infrared thermography cameras is now responsible for parameter exchange as well as for real-time streaming and control of the cameras. In the user interface, the LabVIEW end user now sees the many options for device control as well as the evaluation of the measurement data. We were able to achieve this through several simple and also some extensive examples. Comprehensive documentation makes getting started with the product and device appealing and easy for the LabVIEW user.

  The extensive system tests covered several thermal imaging cameras for different versions of LabVIEW and resulted in more than a thousand test cases for close examination, during which the manufacturer's core device drivers could also be improved in quality. The unit tests of the interface programmed in C++ were created and run for every function and every parameter, and were able to log both limit value violations and timeouts.

Modernisation, optimisation and porting of a large existing AutoCAD extension. Extensive code that has grown over the last 12 years and is now being renewed and restructured by us. Porting of the AutoCAD add-in from ObjectARX to ARX.NET and BricsCAD.

Customer: CAD provider
Technologies: AutoCAD, AutoCAD Civil, BricsCAD, AutoCAD .NET API (ARX.NET), ObjectARX, C#, C++, MFC, COM, Visual Studio, TFS and UML.

• read more
   

  As a B2B software service provider, we used our experience in the CAD field to modernise software that had grown over more than 12 years. Our customer, itself a large software company, had developed this add-in for AutoCAD and Civil for civil engineering.

  Several hundred thousand lines of code were ported and modernised from C++, COM, MFC and ObjectARX to C#, WinForm and AutoCAD's API. This was preceded by a feasibility study and a financial calculation for this large project. In the financial calculation, we showed how the development effort with C++ for AutoCAD add-ins develops over the years due to high migration costs, and over what period the porting to a modern programming language will pay for itself.

  The porting covered the user interface with main and context menus, ribbon, properties window, commands and dialogs. The CAD part included CAD elements (entities), reactors, Xdata and much more. Along the way, it was already apparent that the program code was becoming shorter and simpler.

  After the porting, a three-day training course was held to prepare the staff for the switch to the AutoCAD .NET API with C#. We had previously trained them in AutoCAD's ObjectARX and C++.

Development of new add-ins for Revit covering families, views and filtering.

Customer: Architectural firm
Technologies: UML, Revit, Revit .NET API,  C#, WPF, WinForm, Visual Studio, TFS

• read more

  To make work easier for architectural firms, we developed add-ins for Revit. 

  These compensate for missing functionality in Revit and make the work processes of architects and CAD designers easier. In line with the customer's wishes and requirements, new ribbons were added, special dialogs were developed and filters were programmed.

  In a family editor, all of a project's families or (filtered) only some of them can now be displayed. These can be added to the drawings by drag&drop. In the view editor – for example on a second monitor – existing views can be listed and filtered. In the preview of the view manager, the individual views can be adjusted directly.

Customer: Consultancy for reinsurers
Technologies: UML, C#, SQL, Linq, SQL Server, SQL Server Express, Visual Studio, TFS

• read more

  A consultancy serving reinsurers came to us to bundle its expertise into a software product. This was developed completely from scratch and has a particularly sophisticated design. The customer had previously made its own attempts with Excel and Access and had also commissioned a Bulgarian software company to carry out development work. However, this did not lead to success.

  Cadida Software initially stepped in as a consultant and was able to present technical solutions. Later, at the customer's request, we drew up a financial plan that also made development in Germany possible. Due to the high demands on the design of the user interface, reports, statistics and ease of use, custom controls (WPF controls) had to be developed.

  The system has a central database on the intranet or in the cloud and is based on SQL Server. Our customer passes the software on to its end customers. It allows the end customers to call up and evaluate an overview of their product and staff at any time. An ordering system makes regular ordering of specialist analyses particularly simple.

Software development for detecting the real volume and convex hulls of objects using 3D scanners.

In detail: Rotating Calipers, Minimal Bounding Box, RANSAC, eigenvalue calculation and others. Pre-calculation and testing of the algorithms with Matlab.

Customer: International sensor manufacturer
Technologies: C++, Visual Studio, Matlab, OpenCV, PCL, Halcon, Eigen, UML, SVN, Blender, AutoCAD

• read more

  For an international sensor manufacturer, we developed mathematical models and software algorithms for evaluating 3D scan data. Numerous filters were applied upstream of the evaluation to improve the calculations and optimise the source data.

  The task was to recognise and classify objects from the 3D scan data (point cloud), i.e. to recognise the geometric shape (cylinder, cuboid, sphere, etc.). A subsequent calculation of the volume delivered the desired results with fast performance.

  In the test phase, we installed the scanners at various positions in the laboratory, connected them to the embedded system and configured them. Data from a production plant fitted with the newly developed 3D scanners was also used. To produce a wealth of variants for the tests, we modelled a set-up in 3D for a scan data simulation.

  For an international sensor manufacturer, we developed mathematical models and software algorithms for the automatic calibration of 3D scanners. The aim of the project was to find a simple way of calibrating the scanners worldwide without having to use reference objects or measuring tools.

  The existing calculations were transferred to Matlab, and the set-up of the industrial scanner was also recreated and simulated in Matlab. The scanners could be rotated freely in space to simulate any orientation. For the calculations, the formulas were first optimised in Matlab and then implemented in Java. The user interface was extended, operating steps were minimised and ergonomics improved. Our developments are now used worldwide.

  For the tests, the scanners were installed at various positions in the laboratory, connected to the embedded system and configured. In a simulation that replicated the production set-up, scan data was generated and, after calibration, the calculated positions of the laser scanner were validated.
