The most notable change of 2003 was the introduction of the "34-hour restart." Before the change, drivers could only gain more weekly driving hours with the passing of each day (which reduced their 70-hour total by the number of hours driven on the earliest day of the weekly cycle).
The final rule required truck drivers who use the "34-hour restart" provision to maximize their weekly work hours to limit the restart to once a week and to include in the restart period at least two nights off duty from 1:00 to 5:00 a.m., when one's 24-hour body clock supposedly needs and benefits from sleep the most.

A brain–computer interface (BCI), sometimes called a brain–machine interface (BMI), is a direct communication link between the brain's electrical activity and an external device, most commonly a computer or robotic limb.
IRIG J-1 timecode consists of 15 characters (150 bit times), sent once per second at a baud rate of 300 or greater: <SOH>DDD:HH:MM:SS<CR><LF>. SOH is the ASCII "start of header" code, with binary value 0x01. DDD is the ordinal date (day of year), from 1 to 366. HH, MM and SS are the time of the start bit.
The Sun appears to move in the sky over a 24-hour period while the hour hand of a 12-hour clock face takes twelve hours to complete one rotation. In the northern hemisphere, if the watch is rotated so that the hour hand points toward the Sun, the point halfway between the hour hand and 12 o'clock will indicate south.
The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. Software-compatible with the Intel 8080, it offered a compelling alternative due to its lower cost and increased performance.
Cardiopulmonary resuscitation ( CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth to mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. It is recommended for those who are unresponsive with no ...
