Abstract: A system tracks the position of a container handling vehicle on a grid, following a route relative to rails on a frame structure forming a storage grid. The vehicle has first and second sets of wheels connected to drives for moving the vehicle in corresponding x- and y-directions on the grid. The vehicle receives information of number of rails to pass between start and stop positions in x- and y-directions according to the route from a central computer system. The container handling vehicle has at least one camera mounted underneath to film downwards while the container handling vehicle is in motion, a computer system with an image processing algorithm to process the transferred images and detect the rails in the images, and the camera is positioned so as to be able to capture at least one rail in the x-direction and one rail in the y-direction while the container handling vehicle is positioned over a column.

Abstract: A temperature sensing unit includes a temperature sensor and a substrate including a first region and a second region. The temperature sensor is arranged in the second region. The second region extends away from the first region.

Abstract: A system for detecting the presence of bubbles in a solution includes an ultrasonic receiver, receiving a pair of signals having different frequencies after passage through the solution, and a computing unit. The computing unit computes a signal value for each of the signals, the signal value representing a defined signal property, compares the signal values for the signals with each other and/or each with a predefined reference value, and computes a deviation of the signal values from each other and/or between the signal values and the predefined reference value. The computing unit generates a bubble confirmation signal that confirms the presence of bubbles in the solution if the deviation is greater than a predefined threshold value.

Abstract: A method for detecting a property of a liquid medium comprises generating an ultrasonic pulse, receiving a first echo and a second echo of the ultrasonic pulse transmitted through the liquid medium, and generating a first amplitude signal for the first echo and a second amplitude signal for the second echo. The method includes calculating an amplitude signal ratio between the first amplitude signal and the second amplitude signal and determining a property signal representing the property of the liquid medium.
