Caterpillar Offers New System To Help Combat Driver Fatigue

Developed for the mining industry, it tracks drivers' eyes and uses an audio alert and a vibrating seat to wake them if necessary. In tests, it outperformed other systems that required the drivers to wear special equipment.

What's the Latest Development?


Australia-based Seeing Machines has designed a system called Driver Safety Solution (DSS) that Caterpillar will offer to mining companies to help them manage operator fatigue. It works by tracking the driver's eyes and facial features in order to detect instances of micro-sleep, periods "when a person passes out for...up to half a minute [and] then wakes up again without realising they lost consciousness." If the driver falls asleep, DSS sounds an alarm and activates a vibrating motor in the seat. All components, including the computer mounted behind the seat, are designed to withstand the unique conditions associated with driving mining trucks. Tests conducted at one Nevada site indicated a 90 percent reduction in incidents.

What's the Big Idea?

Fatigue is a huge problem for trucking worldwide, contributing to numerous crashes every year. In addition, according to University of Michigan expert Daniel Blower, "the true incidence of fatigue in truck crashes is likely to be two to three times higher than in the captured crash data." DSS is one of several products designed to combat driver sleepiness. Another monitors steering movements, while still another uses scanners along roads to ensure that trucks stay on path.

What makes someone gay? Science is trying to get it straight.

Evolutionarily speaking, being gay is still something of an enigma

  • Heterosexual people have been less interesting to scientists than gay people, in terms of where they come from, because, evolutionarily speaking, being gay doesn't lead to a higher "higher reproductive fitness" — meaning, it doesn't lead to more babies.
  • Across cultures, gay boys tend to be more interested in spending time with their mothers.
  • We still don't really know why gay people are attracted to each other.

Suppose you forgot it was your partner's birthday, but you know that they would appreciate the smallest of gestures, say a bouquet. It's late at night and no florists are open. The cemetery on your way home has recently had a funeral, and you walk across the site and pick up a good-looking bouquet of roses from someone's grave. You then head home, and the flowers are happily received by your partner.

Would you say that you hurt anyone?
