Abstract: A method for detecting an overload condition of an elevator car of an elevator includes obtaining prevailing car-load information from a load weighing device arranged to weigh a prevailing car-load preferably when the elevator car is standing at a landing floor in an elevator shaft; determining if said prevailing car-load information fulfils one or more overload criteria; and generating a signal indicating an overload condition of an elevator car, if said car-load information fulfils one or more of said overload criteria; obtaining information of at least one operational parameter of the elevator; and adjusting one or more of said overload criteria or said car-load information based on said information of the at least one operational parameter of the elevator. An overload monitoring system and an elevator implementing the method are also disclosed.

Abstract: A sterilization apparatus for sterilizing a respiratory mask is described. The sterilization apparatus comprises a sterilization chamber, an articulating mask support disposed inside the sterilization chamber, a bi-directional fan system disposed inside the sterilization chamber and configured to move air through an air passage to simulate human breathing, and a sterilization agent generator coupled to the sterilization chamber. The bi-directional fan system pumps air that includes the sterilization agent back and forth through the oxygen mask via the air passage, to mimic normal breathing of an individual using the mask.
