CLEANING SYSTEM FOR A VEHICLE COMPONENT
- 2022
-
Patent (övrigt vetenskapligt/konstnärligt)abstract
- A cleaning system for removal of contaminants from a surface of a vehicle component exposed to a gas or fluid flow, the cleaning system comprising: an excitation device adapted to be attached to the vehicle component in the vicinity of the surface exposed to contaminants, wherein the excitation device is configured to cause the surface to mechanically vibrate by transferring a vibrational excitation to the surface; wherein the frequency of the vibrational excitation is controllable to be based on the configuration of the vehicle component as well as other modelled/measured parameters.

Method for measuring cylinder specific parameters in a combustion engine
- 2005
-
Patent (övrigt vetenskapligt/konstnärligt)abstract
- The invention concerns a method to measure parameters in the combustion chamber of a piston engine that comprises an ignition system. An alternating voltage is applied across the secondary winding of the ignition coil and the value of the current that arises in a measurement circuit that co-operates with the secondary winding is measured. The value of the current depends on the resistance (R1) of the measurement circuit, on the inductance (L1) and resistance of the secondary winding, and on the impedance of the combustion chamber, i.e. on its capacitance (C1) and its resistance. For example, top dead centre, the pressure in the cylinder, analysis of the ionic current and change of the burning time can be determined by means of the method

Arrangement and method for marking a log end surface
- 2011
-
Patent (populärvet., debatt m.m.)abstract
- The invention relates to an arrangement (1) for marking a log end surface (4a) with a marking code during cutting of a log (4) and amethod for marking a log end surface (4a)with a marking code. The arrangement (1) is connected to a saw bar (3) comprising a plurality offluid distributing nozzles(6) in communication with a fluid container (16). The arrangement (1) further comprises acontrol unit (CU) arranged to control the flow of fluid through eachnozzle (6)based on log-related identification code. The invention is characterised in thatthe flow of fluid through eachnozzle (6)is controlled based on the movement of the saw bar (3) relative to the log in a cutting direction.

Förfarande och anordning för beröringsfri bestämning av en kropps translations- eller vridningsläge
- 1991
-
Patent (populärvet., debatt m.m.)abstract
- In a method for touch-free determination of the translatory or angular position of a body, a defined measuring path (M) on the body (K) in the direction of said translatory or angular motion of the body (1) is detected spot-wise by means of an optical sensor head (1), which emits laser light towards the measuring path and provides an output signal responsive to light reflected from said path (M), the sensor head (1) and the body (K) with the measuring path (M) being movable relative to each other. In order to provide for an exact position determination with high resolution in an inexpensive way the invention suggests that the surface profile or characteristics of the body (K) along the measuring path (M) is scanned by illumination from the sensor head (1), which consists of an optical pick-up for compact discs.

Mathod for measuring temperature, molecular composition or molecular densities in gases
- 2001
-
Patent (populärvet., debatt m.m.)abstract
- A measuring technique and method are provided to simultaneously determine the molecular density of several molecular species and the temperature within a closed process room in a melting or combustion process. In such processes in the industry, e.g. in metallurgic process industry, it is important to determine the temperature and the contents within the gas or flame without physically connect to or disturb the process. This has shown to raise large problems especially at high temperatures. The radio signal over a frequency band is measured on the outside of the process room through a window in the mantel covering as a function of frequency and registered on a computer as a radio spectrum. The system is calibrated by using a known signal transmitted through the process room. The spectral lines are identified by their frequency from a database. The temperature is determined from several lines of the same molecular specie and the molecular densities are determined from the intensities of the lines. The method is suitable to determine vibrational and rotational excitation of molecular species in the radio wavelength range of 30 micrometers to 500 meters. The densities of molecular species and the temperature can be imaged in three dimensions inside the process room or exhaust channel if interferometers are used for simultaneous two dimensional imaging from several azimuth directions.
