1. 1. Improving Product Level Sensing in Filling Tubes

   Master-uppsats, Lunds universitet/Innovation

   Författare :Hannah Schrewelius; [2023]
   Nyckelord :level sensing; hygienic design; manufacturing; product development; Technology and Engineering;

   Sammanfattning : This thesis examines the possibility to improve the product level sensing in one of Tetra Pak’s filling machines, because the current solution does not detect this with the desirable precision, as well as measuring range. Today, a magnetic float is used together with 16 separate capacitive sensors. LÄS MER

3. 2. PCBA verification and fault detection using a low-frequency GMR-based near-field probe with magnetic closed-loop feedback compensation : A non-contact alternative to physical probing

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Joacim Sundh; [2022]
   Nyckelord :GMR; sensor; magnetic field; near-field; probe; linearity; PCB; coil; PCBA; analogue integrated circuits; analog; operational amplifiers; electrical fault detection; feedback circuits; in-circuit tests; GMR; sensor; magnetfält; närfält; sond; linjäritet; mönsterkort; spole; kretskort; analoga integrerade kretsar; operationsförstärkare; elektrisk feldetektering; återkopplingskretsar; kretskortstest;

   Sammanfattning : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. LÄS MER

4. 3. Development of PMSM and drivetrain models in MATLAB/Simulink for Model Based Design

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Gokul Sivaraman; [2021]
   Nyckelord :Electric Vehicles; Permanent Magnet Synchronous Machine; flux; flux linkage; Inductance; Model based design; Finite Element Analysis; Mechanical drivetrain; Magnetic saturation; Cross-coupling; Spatial harmonics; Temperature; Active oscillation damping; ABS wheel speed sensor; CAN bus.; Elektriska fordon; synkronmaskiner med magneter; magnetiskt flöde; induktans; modellbaserad design; Finite Element Analys; mekanisk drivlina; magnetisk mättnad; magnetisk tvärkoppling; MMF övervågor; temperatur; aktiv oscillationsdämpning; ABS hjulhastighetssensor; CAN buss.;

   Sammanfattning : When developing three-phase drives for Electric Vehicles (EVs), it is essential to verify the controller design. This will help in understanding how fast and accurately the torque of the motor can be controlled. LÄS MER

5. 4. PreCro : A Pedestrian Crossing Robot

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :EBBA HEDBERG; LINNEA SUNDIN; [2020]
   Nyckelord :mechatronics; Pixy2; vision sensor; magnetic encoders; pedestrian crossing; mekatronik; Pixy2; bildsensor; magnetisk givare; övergångsställe;

   Sammanfattning : For people who suffer from visual impairment, getting around in traffic can be a great struggle. The robot PeCro, short for Pedestrian Crossing, was created as an aid for these people to use at pedestrian crossings equipped with traffic lights. LÄS MER

7. 5. Automatic Whiteboard Eraser : A systematic and automated process

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :David Danelia; Nanitza Gonzalez Allendes; [2019]
   Nyckelord :Mechatronics; Magnet; Whiteboard; Continuous rotation servo motor; IR Sensor; Gyroscope.; Mekatronik; Magnet; Whiteboard; Kontinuerlig rotationsservomotor; IR Sensor; Gyroskop.;

   Sammanfattning : The whiteboard is a tool being used in several different facilities around the world. However, erasing the ink off the board can be unnecessarily time consuming and distracting. The purpose of the project was therefore to create a demonstrator to automate the process with a few restrictions. LÄS MER
