Electronics & Connectivity - September 5, 2012 - 3

The ups and downs of connectivity
The best thing about the influx of connectivity in the modern world is connectivity itself. And, the worst thing about the influx of connectivity in the modern world is, well, connectivity itself. Safety and diagnostics are two of the benefits. And, quite frankly, early on that latter “benefit” was not viewed as a benefit at all by those on the ground, and it had some people scared, especially in terms of the on-highway trucking industry. When onboard diagnostics were first making its way into heavy-duty vehicles, the shouts of “Big Brother” where heard all over the snow-ridden hills and through the drought-infested valleys that those trucks, and their operators, had to navigate to deliver their product and do their job. And, at least part of the argument went, those trucks had worked fine up until then. Except when they didn’t. Whether it was an acknowledgement about the importance of the fleet owner to be able to “read” truck health, or whether operators, in time, just acquiesced to the fact that fleet owners weren’t necessarily just “checking up” on the operator, but had a vested interest in the health of their investment—both equipment and personnel—the need for remote monitoring became commonplace (see “Many uses of bearing diagnostic data,” page 11). Nobody wants to be stranded on the side of the road. Or, for that matter, at 36,000 ft in the air. The safety implications of equipment faults take on a whole new meaning at that altitude. Many people reading this column may know more on a personal basis what it’s like to be vulnerable at 36,000 ft than at having several tons of load basically in your back seat at 80 mph. Having connectivity in the engineering basket increases the safety of all, no matter what altitude or what speed. Except when it doesn’t. What engineers have had to learn with their increased tools is that not everyone is as altruistic as they are (see “Securing IT in the sky,” page 14). Let’s face it: while engineers are arguably not underpaid, if one is purely looking for money, there are more profitable paths. Fortunately, for most engineers and SAE members, the altruistic path is, in fact, the only path. But, we are faced with such non-beneficial aspects of connectivity as hackers who have no sincere motive other than doing harm. And such motives must, in terms of safety and security, be factored into the equations and decisions that define the design process. Neither pure design innovation nor out-there engineering brilliance nor the very best, most ingenious, differential equations work any longer in four dimensions. We have to be prepared for the fifth dimension: That of disruption, and, often, pure meanness, to keep everyone safe, no matter what, at any altitude and at any speed. The best thing is: We’re up for it.

electronics connectivity
The creators of SAE International’s portfolio of magazines, newsletters, and websites have developed this new SAE Electronics + Connectivity digital technology magazine to help the industry’s electronic and electrical systems engineers stay up to date on the latest innovations. This “go-to” source for engineering professionals, to be published four times in 2012, covers the engineering of electronics and avionics within the vehicle as well as the systems that connect vehicles to the energy and telecommunications infrastructure. The major content focus is on the engineering of vehicle systems that enable greater performance, safety, and comfort/convenience especially in software and electronic control, in-vehicle networking, and vehicle-to-vehicle and -infrastructure communications. Each issue includes exclusive feature articles along with the best SAE technology articles on electronics and connectivity. 2012 Publishing Schedule March 1 May 30 September 5 November 28
