Apparatus for measuring the operation of vehicular engines
First Claim
1. A measuring device for testing the operation of motor vehicles comprising sensing means for continuously detecting operational signals from a vehicle, means for converting the detected signals into a rectangular wave pulse output signal and for feeding said pulse output signals to a micro-computer, a micro-computer for processing the pulse output signals, storage means to store the processed data obtained from said intermittent processing in said micro-computer, data transmission means to transmit said processed data to an external computer, and display means to selectively display said display processed data, amount of storage space used in said storage means, amount of remaining storage space in said storage means, and switching means to select the display on said display means to allow storage of said processed data into said storage means and to initiate data transmission to said external computer only under the condition when said micro-computer is receiving pulse output signals whereby direct transmission of said data to said external computer is allowed.

Abstract
The operation of a machine, varying with time, is sensed and the signals fed to a micro-computer for processing. The processed signals are stored, varying with time. The stored signals are transmitted to an external computer having display means to display the data, the remaining memory capacity and the holding memory of the storage switches are provided to switch mode of storage of the data, transmission of the data or display.
