Aim

Measurement technologies are increasingly being integrated into everyday products such as mobile  phones which e.g. detects movement to rotate the screen and activity watches that measures heart rate and step count. Modern cars have lane  keeping assistance that detects road markings, distance meters to  vehicles in front to prevent collisions, reverse assistance that detects  distance to obstacles behind, temperature sensors that measure engine temperature and road surface temperature. In light  of the increased use of autonomous systems, e.g. self-driving cars and  the development of drones with their own decision-making ability,  all of which depend on measurements of physical quantities such as speed, direction, position or environmental variables  such as temperature, wind speed or humidity in the roadway, understanding of and skills in measurement  techniques are becoming increasingly vital.

Within  the field of medical technology, the possibilities for diagnostics, including the  possibility of conducting telemedicine or self-care, increase with the possibilities of measurement technology. Within the manufacturing  industry, various industrial processes naturally require comprehensive  and accurate measurement methods to monitor and regulate various  manufacturing processes and material flows. Most sensors that measure physical and chemical quantities produce an electrical  signal which in turn must be detected and interpreted.

The  problem picture includes that there is often a certain measurement  uncertainty whose magnitude must be assessed or that the signal has been  exposed to various interferences that must be restricted. The purpose of the course  is to provide a basic understanding of, and the skills to use, the  measurement technologies and and its associated techniques that detect such electrical signals, as well as  to provide understanding of and skills to assess measurement uncertainties and to restrict interference.

Examination details

Grading scale: UG - (U, G) - (Fail, Pass)
Assessment: Continuous assessment in connection to the lab exercises. Compulsory parts to be passed: Lab exercises including short pre-tests, lab reports and examination of a lab report.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
