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.

Device and a method for preventing or reducing vibrations in a cutting tool
- 2007
-
Patent (populärvet., debatt m.m.)abstract
- An arrangement for reducing vibrations in a tool holder (4) with a cutting tool (3) and has a vibration sensor on the tool holder (4) that is connected to a guide unit (11). The tool holder (4) has further two piezo-electric actuators 14 and 15.Under the influence of the vibration sensor (9), the guide unit (11) provides an electric alternating current that is actively guided over time so that the actuators movably affect the tool holder (4) to reduce the vibrations in this. To also be able to dampen transients in the tool holder (4) this is movably connected with a passive dampening arrangement that is independent of the guide unit (11) and that is based on the principle of a springing (8) suspended mass (7). The invention also relates to a method for reducing vibrations. The vibrations in the tool holder are sensed and a corresponding signal is provided to a guide unit that over time provides actively guided signals to the actuators. The tool holder is also passively influenced by a dampening arrangement that is independent of the guide unit.

Method and a device for vibration control
- 2004
-
Patent (populärvet., debatt m.m.)abstract
- A device for vibration control in a machine for internal turning uses a cutting tool supported by a tool holder, and has a control unit, a vibration sensor connectible to the control unit, and an actuator connectible to the control unit. The actuator has an active element, which converts an A.C. voltage supplied by the control unit to the actuator into dimensional changes. The active element is adapted to be embedded in the body of the tool holder, and is adapted to be embedded in such a manner that the dimensional changes impart bending to the body of the tool holder. A method for vibration control in internal turning and a tool holder for internal turning are provided.

Method and device for controlling a turning operation
- 2005
-
Patent (populärvet., debatt m.m.)abstract
- A device increases the surface smoothness of a turned surface. The device comprising a control system with a control unit and an actuator connectible to the control unit and connectible with a tool holder. The actuator in adapted to impart a vibrating motion in the lateral direction to the tool holder. A method will also increase the surface smoothness of a turned surface, comprising the step of controlling the vibrations of the tool holder during turning. The method also comprises the step of imparting a vibrating motion in the lateral direction to the tool holder. Moreover, a turning lathe and a turning tool holder which like the device are designed to generate vibrating motion in the lateral direction.

Portable rescue device and a method for locating such a device
- 2007
-
Patent (populärvet., debatt m.m.)abstract
- A portable rescue device and a method for locating, by means of a first rescue device set in a search mode, a second rescue device set in a distress mode. In the method, a distress signal carrying a device identification is received from said second rescue device. A first bearing and a second bearing to the second rescue device are obtained. The first and second bearings are taken from a first and a second position, respectively. A distance between these positions is determined. A current distance and a current bearing to the second rescue device are determined on basis of the first and second bearings and the distance. The current bearing and the current distance are communicated to a user of the first rescue device. The portable rescue device is used for performing the method and for that purpose it includes a first communication unit for distress signal transmission and reception; a compass; a processor; a user interface; and a mode switch for switching between a search mode and a distress signal mode. The first communication device has an antenna structure that provides directional capability.

Vehicle steering arrangement, autonomous vehicle steering arrangement, a vehicle, and a method of steering a vehicle
- 2018
-
Patent (övrigt vetenskapligt/konstnärligt)abstract
- A vehicle steering arrangement for a vehicle comprises a rack a position sensor, a steering column, a steering wheel, a torque sensor arranged to sense a torque applied onto the steering wheel and arranged to provide a torque signal representative thereof, an electronic control unit provided with a virtual steering model, a rack-mounted electromechanical actuator, and a force obtaining arrangement configured to obtain forces of steered wheels acting on the rack. The electronic control unit is configured to provide a virtual rack position based on the virtual steering model and at least a combination of the obtained forces and the torque signal, and is arranged to control the rack-mounted electromechanical actuator such that the current position of the rack is controlled towards the virtual rack position. The present disclosure also relates to an autonomous vehicle steering arrangement, a vehicle and a method of steering a vehicle.
