Determining lifting events using sensors for person lifting apparatuses

A person lifting system comprising:

• an overhead rail that is secured to a ceiling of a room;
• a person lifting apparatus that is movably connected to the overhead rail, the person lifting apparatus comprising:
• a lifting strap;
• an actuator operative coupled to the lifting strap for raising and lowering the lifting strap;
• at least one of
• (i) a current measuring device configured to provide current load information to a computing device;
• (ii) a position sensor configured to provide strap position information that is indicative of a paid out length of the lifting strap to the computing device;
• and
• (iii) a weight sensor that is configured to provide weight information that is indicative of a load supported by the lifting strap;
• and
• the computing device comprising a processor using logic saved in memory that, when executed by the processor:
• receives at least one of the current load information, the strap position information and the weight information;
• and
• identifies at least one of a raising event, a repositioning event and a lowering event based on the at least one of the current load information, the strap position information and the weight information.
