HIGHLIGHTS   Our client – a globally represented supplier of scientific instrumentation – involved PSA in their efforts to optimize the dosimeter calibration process that is executed using a range of radiation sources. Intending to launch a new generation of personal handheld dosimeters, they augmented the calibration equipment with a new device compatible with both existing and upcoming models of dosimeters. The crucial step of this optimization was to provide an opportunity for real-time remote monitoring and control of the whole calibration process for all types of dosimeters, including configuration, opening of the radiation source, and the transportation of dosimeters between irradiation stations. CHALLENGE Client Challenge   Reduce the costs for calibration of personal handheld dosimeters considering the launch of the new model. Project Objective Ensure precise and convenient calibration for multiple types of dosimeters while also increasing process performance. SOLUTION   To provide comprehensive management of the dosimeter calibration processes, the PSA team developed desktop and web tools that allow for control of the augmented calibrating machine. In real-time, the application collects and sends data to dosimeters under calibration, the transportation system of the calibrating machine, and the irradiation source module, which contributes to the following functionality:   1. Radiation dose management for the particular types of dosimeter; open/close status for exposure source.   2. Establishment of position for dosimeters, and their moving between irradiation stations at the required direction   3. Adjustment of dosimeters’ settings in accordance with their response to exposure.   4. Delivery of calibration reports and provision of secure automatic data export to the centralized production management system   5. Studying the history of dosimeters calibration configuration, process, and results.   The PSA team designed the application from scratch starting with the complex architecture design, followed by implementing algorithms for dosimeters calibration, developing UI, and conducting onsite testing. During the project, we utilized real client dosimeters and IR readers, simulating doses and detector counts, and the imitation of the robotic system that  transports the dosimeters between irradiation stations. To ensure performance is maintained in terms of data size increases, we connected the app to an SQL server. Also, our team implemented multi-tasking for the updated calibrating machine, which allows for simultaneous irradiation of several dosimeters. These features together with a responsive UI contributed to the ultimate performance and throughput of the system.   As a result, the threshold and sensitivity of the various types of client-produced dosimeters are set in adherence with the instructions of the PSA-delivered app. The client receives calibration verification, analysis, and reporting for every produced dosimeter, which helps verify the devices before sale. The high accuracy of calibration allows for the usage of personal handheld dosimeters for scientific, industrial, medical, and other purposes. DEVELOPMENT INCLUDED   1. Requirements definition 2.

HIGHLIGHTS After the successful delivery of a number of projects, we continued cooperation with our client, a leading manufacturer and supplier of scientific radiation measurement equipment. For certification purposes, Electronic Personal Dosimeters (EPDs) have to be checked annually and calibrated if necessary. To perform calibration checks for dosimeters, the client needed a flexible and scalable tool that could interact with all the 3rd party irradiators used for this purpose.   CHALLENGE   Client Challenge   Simplify the process of issuing certificates for the multiple types of EPDs, including models currently in development. Project Objective Expand the functionality of the calibration-check system to ensure simple annual verification for various types of dosimeters, which allows for adding new devices and remote access. SOLUTION   To ensure rapid and reliable dosimeter calibration checks, the PSA team developed a software solution that interacts with irradiators to perform these checks in real-time. It acts as a central repository for the EPD calibration and related data, providing an external interface to the calibrating system. The application allows for the following actions:   1. Choose a procedure for the calibration check from the list   2. Get procedure configuration parameters   3. Verify calibration check results for each EPD   4. Receive and print reports   5. Manage users, lists of irradiators, procedures, EPDs, and calibration check results During the project, the PSA team solved the issue of scalability, thus allowing the delivered software to interact with the legacy, new, and prospective generations and types of dosimeters launched by our client and 3rd party irradiators. To promote scalability, we ensured the calibration check configurations include facultative elements that can run only if they are defined in the database. Thus, the PSA-designed interface allows for:   1. Adjustment to capabilities of various irradiators, including various sources, dose rates, capacity, throughput, and levels of automation   2. Adjustment to the more advanced EPD concepts such as detector counter readings, detector gains, and partial doses   3. Compliance with application-dependant technical recommendations   4. Addressing specific issues that a customer might face. ?For the third-party irradiators to be seamlessly connected, we created APIs for the calibrating system.

HIGHLIGHTS We were contacted by our regular customer – a leading provider of IoT and M2M connectivity equipment. Their cellular on-board diagnostics (OBD) device was expected to be implemented in vehicles, predominantly trucks, to help prevent accidents and detect incorrect driving. However, the system couldn’t perform updates via air, had poor functionality and connectivity capabilities, and lacked many parameters to be tracked. CHALLENGE Customer Challenge   Ensure a simple and available real-time monitoring of the vehicle fleet and traffic situation, as well as advanced EIoT analytics opportunities to prevent dangerous cases and optimize transportation expenses.   Project Objective   Enhance the ODB device to continuously detect problematic driving while supporting the requirements of a highly organized IoT ecosystem.   SOLUTION   Since the device was expected to process a large amount of driving data simultaneously, the system was built on ThreadX – the modern RTOS that supports multiple threads.   To prevent accidents and incorrect driving, the system was designed to detect excessive acceleration, sharp cornering and hard braking during vehicle motions. To reduce the cost of production without reducing the quality of the device, together with the client we decided to use only an accelerometer module without a gyroscope. Considering the lack of gyroscope and variations of the installation position of the device inside of a cab, we created a specific and highly complex algorithm for computing accelerometer data to calculate installed device orientation, movement vectors, and critical road situations.   To optimize the device and satisfy the requirements of the IoT ecosystem, we provided the system with the following functionality and capabilities:   1. Enhanced tracking capabilities;   2. Low energy consumption wireless communication;   3. Highest availability in difficult-to-reach areas;   4. Opportunity to update the device via the air.  For this, we implemented support of the interfaces for GPS, LTE CatM radio, and Bluetooth. We also developed firmware to support the deployment of the existing OBD III Streamer device based on the Quectel BG96 module. We made a great effort here, since the module does not provide a built-in debugging possibility and usable firmware update procedure. To provide communication between the device and the cloud, we implemented a central server communication logic.  To ensure the system tracks location and performs diagnostics precisely, we performed production testing in about 1100 vehicles. Thus, we were sure that our client can guarantee full tracking and predictive maintenance of the whole vehicle fleet. DEVELOPMENT INCLUDED   1. Protocols review and analysis;   2. Implementation of different interfaces and business logic;   3. Accelerometer data processing implementation;   4. Firmware development and implementation;   5. Testing and debugging.

HIGHLIGHTS We were contacted by a large international privately-held manufacturer and provider of irrigation products which are designed to minimize water consumption. They’ve been running a widget system on their control platform to provide their customers with data about current weather. CHALLENGE Customer Challenge The widget system that was implemented on the platform did not allow their clients to get full weather info from different areas, and forced them to use other resources to monitor the areas that were not covered. The installed system showed the widget for only one particular zone, and displayed only a few basic weather parameters such as temperature and humidity. Thus, our customer risked losing their position in the market if they did not upgrade their system with new features. Project Challenge   The initial purpose of this project was to develop a Web Widget for up-to-date Hyperlocal Weather information with regards to location, using an API provided by a 3rd party. Users of the controller should be able to add several widgets to the platform and see more weather info. Since the customer already had a widget system, our designer and front-end developer needed to fit the design into the fixed widget sizes.   After the start of the project, we realized that it would be nice for the client to validate the customer’s access to the widget and the information inside it. So, the challenge for the backend developer was to integrate an additional microservice with the initial software architecture. Thus, we had to create not just a specific widget, as planned initially, but an infrastructure that can be used by the client for adding any widget to the panel providing information from any 3rd party vendor.   SOLUTION While developing this app we used an agile methodology, and the development model was a mix of waterfall and spiral models. The delivered solution consists of 4 main structural elements on a high level:   1. Browser-based frontend part adapted for desktop and mobile platforms   2. PC based backend core, API for interaction with frontend and cloud, and DB management services   3. Cloud-based data user and management service   4. 3rd party weather information service   The selection of the technologies was determined by the fact that we developed the add-on for an existing piece of software, so it was an Angular framework for the frontend and .Net for backend-related parts.   To put the system of interaction with the weather data provider into a separate module, we decided to use a cloud solution. As a result, we got a separate server that downloaded weather data from a particular resource and transmitted it to end-users, provided with security settings and a licensing system. Thus, we have designed an infrastructure that allows the client to create widgets, control subscriptions and payments.   Our developers have also performed engineering and unit tests of the delivered solution. Over 70 e2e test cases were prepared and executed by the QA team. The project code was then pushed to the customer’s repository for future merge with the main product codebase.   DEVELOPMENT INCLUDED   1. Building system infrastructure   2. Architecture design   3. New features implementation   4. Backend development   5. Frontend development   6. Integration and functional testing.   RESULT   The client received a system capable of displaying multiple weather widgets, allowing the operator to monitor up to 8 different weather parameters in various zones. Info in the widget system is presented in a readable form inside the in-app widget, split by hour, day and week. The solution supports automated and on-demand updates, cloud and local storage of historical data, and user validation.   Also, the client got a flexible platform for future implementation of different widgets which can obtain information from 3rd party vendors.   The delivered solution allowed not only to show the current state of the weather, but also to store, collect, and process data, turning the system into a full-fledged ecosystem of the Internet of Things.   Since the client sends solutions to more than 130 countries, it will not be difficult to internationalize the widget if necessary thanks to UI string values.   TECHNOLOGY BREAKDOWN Technologies   1.

HIGHLIGHTS   We were contacted by a supplier of wireless fuel management solutions, whose product line opens great opportunities for advanced BI for fuel distributors, commercial fleets, and automotive aftermarket companies. The Fuel Dispensing System is one of the client’s products that allows tracking of fuel consumption by users, which made the system widely used within private fueling stations. Since the solution contained 3rd party hardware, its production, maintenance, and customer support were too costly with the average set of functions. This forced the customer to “redevelop” the existing system to expand its functionality and reduce the cost of its components. CHALLENGE   Customer Challenge   Reduce the cost of production of the fuel dispensing system hardware, while expanding the range of its use cases. Project Objective   Develop an alternative fuel dispensing solution with extended functionality and more affordable hardware components. SOLUTION   The PSA team developed the Fuel Dispensing System with access control and fuel level tracking which enables sharing of fuel tanks. To lower the cost of the components we designed and developed the customized hardware for the system which consisted of the following:   1. A fuel pump controller that is integrated with a pump, collects and processes the data from sensors, and sends it to the server   2. Control pad that allows for management of the system and provides visual and audio signals   Guided by the DFM approach, we optimized the cost of HW production by selecting reliable and efficient components and modules provided by our partner Toradex at affordable prices. Since the customer hadn't provided us with the components and suppliers they preferred, we utilized our own expertise and conducted detailed market research, defined functional requirements, and chose cost-effective and weather-resistant components that fully satisfied the functional requests. We provided the Fuel Dispensing System with the following features:   1. Wireless (Bluetooth, WiFi) and cellular (4G) communication networks   2. GPS navigation   3. Support of large screen color displays    4. Advanced technology in data management   5. Backward compatibility with existing hardware and software   To ensure this, we performed schematics, PCB-layout, and mechanical design for both the Fuel Pump Controller and the Control Pad, then developed firmware for them. After developing and flashing the system, the Control Pad freely communicates with the Fuel Pump Controller that communicates with the web server.   The Control Pad that we developed supports the LCD display, keypad, keyboard, and LEDs matrix. Access is controlled via iButton, Magnetic card, and RF Tags. We ensured its protection from intruders and operation in harsh conditions through tamper-proof housing.   To manage the Fuel Dispensing System and monitor fuel consumption, we developed a web configuration console that allows display of:   1. Online status of the Fuel Dispensing System   2. Internet connection   3. Fuel Pump Controller and the Control Pad status   4. Fuel level, overfill, and interstitial sensors status   5. White list of the users/vehicles   6. Pump motor status   7. Current and last counters   We ensured full control of the whole Fuel Dispensing System status and provided the users with data about the processor, allocated and free memory, OS and firmware versions, LEDs, system uptime, and app’s start count.   At the output, the client got 5 tested PoC hardware units for the Fuel Pump Controller and the Control Pad which can be controlled and updated remotely. The system was accompanied by documentation that allows for launch to mass production. DEVELOPMENT INCLUDED   1. Requirements definition   2. Hardware components selection   3. Schematics design   4.
