| 1999 | Invention patented by Alvaro H Fragoso and Albert C Hinojosa on June 3rd, 1999. Abstract: A daily log device for recording the daily activities of a driver. The daily log device includes a clock indicating a time and date, a first signal generator for generating a signal representative of the driver being on duty and a second signal generator for generating a signal representative of the driver being off duty. A microprocessor is connected to the clock, the first signal generator and the second signal generator and includes a memory. A printer is connected to the microprocessor for printing the daily log. The microprocessor stores a time and date at which the first signal generator is activated and a time and date at which second signal generator is activated in the memory and calculates a time period between activation of the first and second signal generators. The daily log indicates the time the first signal generator is activated, the time the second signal generator is activated and the calculated time between activation of the first and second signal generators. The first signal generator can also divide the on duty time between times the driver is on duty and driving and times the driver is on duty and not driving. These time periods will also be calculated by the microprocessor and printed on the daily log. |
