A voltage source converter includes two half bridges each having two current valves connected in series to be connected to opposite poles of a DC source/load. A gate drive unit controls a semiconductor device of a current valve. An arrangement carries out voltage measurements for providing a value of DC voltage between the opposite poles. A voltage divider connected across the two current valves measures DC voltage between opposite poles and each voltage divider has an output connected to processing parts delivering a digital signal representing a value of the DC voltage between the poles. Two gate drive units send a digital signal to a calculating unit to carry out a quality estimation of the digital signals and to calculate a DC voltage value from the signals while giving each signal a weight corresponding to the quality value adhered thereto and then forming a weighted average value.

Voltage source converter and a method for operation thereof

A method for calibrating a robot coordinate system of a robot with a conveyor coordinate system of a movable conveyor member, the method including providing a sensor configured to detect positions of the robot in a non-contact manner; detecting a position of the robot when the conveyor member is positioned at a first operating position; detecting a position of the robot and/or of the conveyor member by the sensor in the sensor coordinate system when the conveyor member is positioned at a second operating position different from the first operating position; and determining a relationship between the robot coordinate system and the conveyor coordinate system based on at least one detected position of the robot in the sensor coordinate system. A robot system and a control system are also provided.

Robot-conveyor calibration method, robot system and control system

Robotic visualization systems and methods include running and analyzing perception algorithms and models for robotic visualization systems on multiple computing platforms to obtain a successful complete an object processing request.

Distributed inference multi-models for industrial applications

A method for controlling movement sequences of a robot, the method including predicting values of at least one parameter related to the execution of alternative movement sequences by the robot, where each movement sequence includes at least one movement segment associated with a handling location; selecting a movement sequence based on the predicted values of the at least one parameter; and executing the selected movement sequence by the robot. A control system for controlling movement sequences of a robot is also provided.

Method and control system for controlling movement sequences of a robot

A robot is configured to perform a task on an object using a method for generating a 3D model sufficient to determine a collision free path and identify the object in an industrial scene. The method includes determining a predefined collision free path and scanning an industrial scene around the robot. Stored images of the industrial scene are retrieved from a memory and analyzed to construct a new 3D model. After an object is detected in the new 3D model, the robot can further scan the image in the industrial scene while moving along a collision free path until the object is identified at a predefined certainty level. The robot can then perform a robot task on the object.

Method and system to generate a 3D model for a robot scene

A monitoring system and method for monitoring and/or predicting drowsiness of a driver of a vehicle or a machinery operator are provided. A set of infrared, IR, or near infrared, NIR, light sources, is arranged such that an amount of the light emitted from the light source incidents on an eye of the driver or operator. The light that impinges on the eye of the driver or operator forms a virtual image of the signal sources on the eye including the sclera and/or cornea. An image sensor obtains consecutive images capturing the reflected light, wherein each image will contain glints from at least a subset or all of the light sources. A drowsiness index can be determined based on the extracted information of the glints of the sequence of images, wherein the drowsiness index indicates a degree of drowsiness of the driver or operator.

Eye closure detection using structured illumination

The invention generally relates to systems and methods for eye detection for use in, for example, installations and systems for tracking eyes and gaze angle/directions. The system includes a plurality of eye detection units connected to an image sensor. The eye detection units are adapted to receive regions of picture elements of a digital image frame substantially in parallel and wherein the eye detection units are adapted to operate substantially in parallel, each eye detection unit being adapted to receive a specified region of the picture elements of at least one digital image frame and including an eye feature extraction module adapted to perform a eye feature extraction process on the received picture elements to identify predetermined eye features. An eye data generating module is adapted to receive information of potential identified eye features including picture element coordinates for the identified eye features, and the received region of picture elements, and generate eye data based on the information of potential eye features, wherein the eye data is generated if identified eye features fulfill predetermined conditions, and transfer generated eye data and the received regions of picture elements to a processing module, and wherein a data flow of the eye data and the region of picture elements of a digital image frame is substantially parallel.

Eye detection unit using sequential data flow

A monitoring system monitors and/or predicts drowsiness of a driver of a vehicle or a machine operator. A set of infrared or near infrared light sources is arranged such that an amount of the light emitted from the light source strikes an eye of the driver or operator. The light that impinges on the eye of the driver or operator forms a virtual image of the signal sources on the eye, including the sclera and/or cornea. An image sensor obtains consecutive images capturing the reflected light. Each image contains glints from at least a subset or from all of the light sources. A drowsiness index can be determined based on the extracted information of the glints of the sequence of images. The drowsiness index indicates a degree of drowsiness of the driver or operator.

A method for processing a signal includes monitoring an over-sampled signal to detect deviations in a number of fill samples, and providing an electronic delay adjustment to a signal path. If a deviation in the number of fill samples is detected, the electronic delay adjustment from the signal path is removed in one or more steps until all of the electronic delay adjustment is removed from the signal path.
