A leak detector is disclosed. The optical leak detector may include a sensor module for transmitting and receiving signals corresponding to the surface level of a monitored fluid and include leak detection logic for detecting a leak signature. The leak detection logic may be configured to determine if fluid contained in a tank is in a non-full state outside of a normal state and activate an alarm.

Method and apparatus for leak detection

A servosystem, in particular a servosystem for a motor vehicle, includes a display showing a list of clickable menu items, a rotary knob with a rotary element to operate the rotary knob, with a number of mechanical detents to alternately increase the rotary momentum necessary for rotating the rotary element, with a brake to brake the rotary element and with a rotation sensor to measure the rotation of the rotary element with a resolution that is the least four times, in particular at least six times, and with particular preference at least eight times the number of mechanical detents per rotation of the rotary element, and a control for converting the rotation of the rotary element into a scrolling motion through a list and for activating the brake when the last clickable menu item of the list is reached or the first clickable menu items of the list is reached.
