  1. 1. An amplitude modulated laser rangefinder : electronic circuit design and implementation

    University essay from Uppsala universitet/Signaler och system

    Author : Fazel Naser; Stefan Morin; [2022]
    Keywords : Amplitude modulation; Phase shift; Laser rangefinder; Drive electronics; PCB; Colpitts crystal oscillator; Transimpedance amplifier;

    Abstract : This report describes the design and implementation of a prototype for an amplitude modulated laser rangefinder, which is made on a PCB consisting of a laser module emitting light, a photodiode receiving the light reflected from the target, and other components. The design is made for the different power levels, generation of the modulation output and the reception of the signal. READ MORE

  2. 2. Submillimeter 3D surface reconstruction of concrete floors

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Björn Hagström; Hampus Wallström; [2022]
    Keywords : Submillimeter; Structured light; Sinusoidal phase shift; Concrete; Surface reconstruction; Defocused binary pattern;

    Abstract : During the creation of any concrete floor the concrete needs to be grinded down from it's very rough newly poured form to a more usable floor surface. Concrete floor grinding is very special in that the work area is often immensely large while the height difference on the surface is incredibly small, in-fact the the largest local difference of the surface from a peek to a valley during the grinding process is submillimeter and goes down to micrometer scale.

  3. 3. Estimation of Stability Margins for the Closed-Loop Air Charge Control of an Internal Combustion Engine Using Sinusoidal Disturbances

    University essay from Linköpings universitet/Fordonssystem

    Author : Victor Sundelin; Filip Jussila; [2021]
    Keywords : Estimation; Stability Margins; Closed-Loop; Air Charge Control; Internal Combustion Engine; ICE; Sinusoidal Disturbances;

    Abstract : The vehicle industry have for many years improved the design of car motors and iterated the control systems associated with it. The systems have become very complex and hard to understand because of this work process. READ MORE

  4. 4. Visual Contribution in Human Postural Control

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Per-Anders Fransson; Patrik Sundström; [1991]
    Keywords : Technology and Engineering;

    Abstract : An important function for the human body is the ability to maintain balance. This has been compared to a sixth sense whose function we would have difficulties to be without. The system of balance is a complex system which uses several different sensors to get a satisfactory image of the position and motion of the body. One of the sensors is vision. READ MORE
