Abstract: A real time video data acquisition system is provided in accordance with the teachings of the present invention wherein one or more blocks of data is stored in serial form on one horizontal scan line of a video picture. Each block of data may consist of a synchronizing word followed by a plurality of data words in the form of an array of digitized analog samples. The data words in eahc block may represent multiplexed data from several measurement instruments or data from a single measurement instrument sampled at a high rate. The video information is presented in remaining horizontal scan lines and audio information is presented in the conventional manner of a video system. Each block of data may be updated once per video field, the data being stored synchronously with a record/recovery clock whose frequency and phase are controlled by the video signal. The invention thus presents, in real time, video and audio information together with data measured.

Abstract: Driver-vehicle behavior display apparatus is provided wherein data representing a vehicle's performance capability envelope and a polar plot of forces imposed by a driver on a vehicle are superimposed in real time upon video information representing a driver's view of roadway being traversed. In addition, bar graph information corresponding to accelerator position and brake pressure may also be provided and superimposed upon such video information. The resulting video signal may be viewed directly, transmitted to a remote viewing station, or recorded in a conventional VCR.
