1. An elevator inspection apparatus, comprising:

  • a commercially available off-the-shelf computing device comprising a computing processor for running computer programs, an electronic memory used by said computing processor while running a computer program, an electronic storage for indefinitely storing data files and computer programs, an electronic display for displaying graphics to a user, a power source, and an interface for communicating with and providing power to a physically separate sensor package;

    a sensor package, physically separate from said computing device, comprising a sensor for measuring the acceleration of the elevator car, a door sensor for determining the position of the elevator door, an altimeter for measuring the altitude of the elevator car, and an interface for communicating with and receiving power from said computing device;

    a communication mechanism between said computing device and said sensor package whereby said communication mechanism provides two-way communications between said computing device and said sensor package, and said communication mechanism provides power from said computing device to said sensor package;

    a computer program stored in said electronic storage and running in said computing processor that repetitively requests acceleration measurements, door positions, and altitude measurements from said sensor package and analyzes said acceleration measurements, door positions, and altitude measurements, and manages the functions of said elevator inspection apparatus;

    whereby said computer program computes the beginnings and ends of every trip of the elevator car so that the user need not indicate the beginnings and ends of any trip to said elevator inspection apparatus; and

    said computer program computes the accelerations, velocities, jerks, door positions, landings, trip start times, trip end times, trip directions, and trip durations of the elevator car for every trip, displays the results of the computations on said electronic display, and stores the results and times of the computations for every trip in said electronic storage so that the number of results that are stored is limited only by the size of said electronic storage.
