Abstract: The solution relates to controlling a generation of an elevator landing call. In the solution, at least two different types of sensors are monitored. In response to a detection that the at least one first type sensor generates an indication on a detection, data indicating a detection by the at least one second type sensor is inquired. If the data inquired does not indicate the detection by the at least one second type sensor a signal is generated causing the generation of the elevator landing call. If the data inquired indicates the detection generated by the at least one second type sensor a generation of the signal causing the generation of the elevator landing call is prevented.

Abstract: An apparatus is described. In an embodiment, the apparatus comprises an illumination unit configured to simultaneously illuminate a first portion of a scene with unstructured light and a second portion of the scene with structured light. The apparatus further comprises a digital image capture unit configured to capture at least one image frame of the illuminated scene.

Abstract: In one example, an apparatus comprises a battery that has a first characteristic capability for providing continuous power and a second characteristic capability for providing intermittent power to the apparatus. The apparatus further comprises an illumination unit. The apparatus further comprises a controller that is configured to determine the total current consumption of the apparatus, determine the amount of battery current available to the illumination unit, and adjust current consumption of the illumination unit based on the determined available amount of battery current to ensure that the current consumption of the illumination unit stays below a battery safety circuit current limit.
