The method according to the invention is a method for safeguarding the car of an elevator, which is provided to form regular unlocking zones in the region around the envisaged stopping points at the stories, against unintended movement. The method monitors the speed of the car, the height position of the car in the elevator shaft and the status of the locking of the car door, and identifies possible stopping of the car, the height position of the car outside a regular unlocking zone, and a possibly unlocked state of the car door. A first sub-method of the method forms a temporary unlocking zone when the car stops outside a regular unlocking zone with the car door unlocked, and it assigns the temporary unlocking zone an upper and a lower boundary above and below the position where the car stops.

A time-of-flight (TOF) sensor device includes: an illumination component that emitting a light beam toward a viewing space; a receiving lens element receiving reflected light and directing the reflected light to a photo-receiver array; and a processor. The processor is configured to generate distance information for a pixel corresponding to an object in the viewing space based on time-of-flight analysis of the reflected light; record a variation of an intensity of the reflected light from the object over time to yield intensity variation information; record a variation of the distance information for the pixel corresponding to the object over time to yield distance variation information; and apply a correction factor to the distance information in response to a determination that the intensity variation information and the distance variation information do not conform to an inverse-square relationship.
