Test Circuit

 ”Human-Inter-what?” clipped Simon, peeking over his morning paper with a loud crinkle. A favorite farmer of seventy-eight years at my local coffee shop, Simon never failed to give me the truth precisely as he saw it. I had asked him what he thought of Human Machine Interface Technology. “Sounds like science fiction to me. Don’t we already interact - interface, whatever - with machines? How else are we supposed to run the things?”

I laughed, but in a down-to-earth, back-to-common-sense way, Simon was right on. One encyclopedia explains Human-Machine Interface (HMI) technology, also known as user interface technology as the whole means by which human users interact with a particular system, such as a device, computer program or machine. HMI provides a mechanism by which users can input or manipulate a system, and provides the system a way to output or produce the effects of the users’ manipulation.

It’s not really so complicated. HMI is a broad term describing the “layer” between a person interacting with the machine and the machine itself. Applications are varied - from medical prostheses, such as cochlear implants, to computer-human interactions to the operation of vehicular Global Positioning System (GPS) devices.

For example, Web-based user interfaces accept input and provide output by generating Web pages transmitted via the Internet, which are then viewed by users through Web browser programs. Different implementations are utilized to provide real-time control in a separate program, effectively abolishing the need to refresh a traditional HTML-based Web browser.

The more exciting technologies include touch interfaces, which serve as excellent examples of the public’s increasing demand to be in control of their environment and their machines. Touch interfaces are graphical user interfaces using a touch-screen display as a device for both input and output.

This insistence is becoming apparent in the automotive industry, where consumers are demanding to be well-connected and in control. Most vehicular GPS devices, for example, are touch interfaces. Steering wheel controls can also use HMI technology to keep drivers connected through different wireless and electronic apparatuses. Certain corporations are even releasing vehicles in which much of the cockpit is run by HMI technology, such as reconfigurable instrument clusters, reconfigurable head-up displays (HUD), warning systems and multifunctional controls.

The trend seems to be in fewer gauges - reducing six-gauge systems, for example, to fewer with reconfigurable displays. There may be more use of a center cockpit, touch screens and reconfigurable thin film transistor (TFT) displays in the future, as well.

A report about HMI technologies stated the importance for designers to understand that HMI determines an operator’s perception about a machine. Designers are of vital importance, it went on to say, because operators need to be able to trust the apparatus - and trust their interactions with it - in order to make the technology successful. How skillful and mindful HMI designers are in their work will, in large part, determine that. HMI empowerment will come through ease-of-use features, ease of programmability, easy understanding and clear information displays.

According to that study, a portion of the designer population still considers HMI just a tool, but many technologies with vital benefits are poised to make HMI the central command station for monitoring and control operations. This technology has the power to transform equipment into better interactive instruments.

Focus will increasingly be on the integration of hardware and software across horizontal and vertical lines, as well as on security issues associated with HMI software, supervisory control and data acquisition (SCADA) systems. Escalating complexity and the high volume of connections requires this to be of current and future concern. Likewise, agility and portability are proving to be important trends in human-machine interaction and user experience research.

Buying a Used Car Online
By Jay Gaulard

 There are a couple of major benefits to buying a used car online. You do not have to spend hours going from one dealership to another. Even better, you will not have to deal with overly pushy salespeople attempting to sell you more than you can logically afford. You can always look through your local newspaper’s online automotive classified website.

Tip #1 - Before Buying a Used Auto

Before buying a used car online, learn everything you can about what it should and could include. Learn about both standard and optional automotive equipment and the fair market value for the used car. Also, consider your budget. Knowing how much you have available before you start looking will help narrow down your choices. You will also be less tempted by an unaffordable auto.

Examine exactly why you want to buy a used car. The way you will use it can have a big impact on what type of auto you purchase. If you need an automotive for family outings or carpooling, a 2-seater sports car will not work.

Tip #2 - Questions to Ask Auto Seller

Ask the seller the following questions before buying an automotive online:

* Why are they selling the car? Beware if their reason seems unreasonable.

* Do you have service records? Having the service records will let you know what required services have and have not been completed. This will help you determine possible costs after you have purchased the auto.

* Is the title in the seller’s name? It can be difficult and time consuming to get the title changed from a previous owner. Another possibility is that you or the seller may be unable to locate the previous owner

* Are there any liens attached?

* Can I have an independent mechanic physically inspect the used car?

* Can I test drive the used car before buying it?

Tip #3 - Pictures of the Used Auto

Whenever possible, check out the used car in person. Otherwise, ask for pictures of the vehicle from every angle possible (inside and out), including the engine. Although not a sure-fire way to verify if the seller is being completely honest, this can help you to avoid some surprises. Even with pictures, you still need to be careful. Read over the original description of the used car and verify that it matches the one in the photo.

Tip #4 - CarFax Automotive Report

Ask the seller for the vehicle identification number, which you will need to run a CarFax report. This is a necessary step to protect you from fraud. A CarFax report will show you most major completed repairs and whether the car has been involved in an accident. If the report shows the vehicle has been in a bad accident, but the seller says the car is in tip-top shape, consider buying a different vehicle.

Tip #5 - Automotive Pricing

Before shelling out money or agreeing to a sales price, visit the Kelly Blue Book or Edmunds website to find the fair market value of the auto. Do this after you have seen pictures of the car so that you can be accurate about the car’s condition. Keep in mind that the sales price listed online probably does not include sales tax, registration, financing fees, or licensing and title fees.

Tip #6 - Where to Buy a Used Auto

You have several options regarding where to buy a used car online. Try looking through online automotive classified ads or on dealer websites. Another possibility is visiting online auto auction sites. Whichever way you choose, always follow the previously provided tips before making a purchase.

For many reasons, buying a car online can be much trickier than buying one in person. This is especially true when you decide to buy a non-local car, as you normally will not be able to see the car in person before you get it. Following the tips above can do away with many of the pitfalls.

Auto review - Ferrari California vs. Jaguar XK Convertible
By Anthony D. Morgan

 The new Ferrari California will satisfy even the most demanding of owners in term of its superb vehicle dynamics and driving pleasure. The new model will be available exclusively as a convertible with a folding hard top. Both chassis and bodywork are aluminium, in line with the rest of the current range. The California will be powered by a new V8 engine mounted for the first time in the marque’s history in the mid-front position.

As per the traditional Ferrari transaxle layout, the engine, which allows the Ferrari California to sprint from 0 to 100 km/h in less than 4.0 seconds, will be coupled to a 7-speed dual clutch transmission that boosts the car’s performance while enhancing the driving pleasure, improves ride comfort and reduces fuel consumption and emissions (c.310 g/km CO2). The comfort is further enhanced by a new multilink rear suspension system. The Ferrari California is also equipped with the exclusive F1-Trac traction control system which made its debut on the 599 GTB Fiorano and has been further honed to suit the typical driving conditions expected for this new GT. Brembo brakes featuring carbon-ceramic material disks as standard guarantee superbly efficient braking.

The Ferrari California is aimed at owners who desire a car which embodies everything the Prancing Horse represents in terms of sporty design and innovation, but also seek a car with greater versatility than ever. The car will be officially unveiled to the public at the Paris International Car Show. However, over the coming weeks, new photographs and further details about it will also be published.

The all-new Jaguar XK Convertible is visibly more assertive and sportier than the model it replaces, but in true Jaguar tradition it is also elegant, understated and mature. In hard-top guise it has classic, ground-hugging Coupe proportions, with long hood, steeply raked windshield and rear window, arch-filling wheels, and minimal overhangs. The front-wing power vents are a new Jaguar styling signature recently seen on the special edition XJ Super V8 Portfolio; the distinctive oval grille opening, prominent hood power-bulge and practicality-enhancing rear Liftback all echo the classic E-type, while details like the sweeping front and rear light shapes and powerful stance catapult Jaguar sports car design firmly into the 21st century.

The sleek Jaguar XK Convertible is an adept combination of style and substance. The car rides on a lightweight yet rigid aluminum structure, yielding a sporty nature with a quiet and sophisticated ride.

It has a powerful V8 engine, which drives the rear wheels with a six-speed automatic transmission that allows manual operation via steering wheel-mounted paddles. It has a high level of standard equipment and few options, including adaptive cruise control which maintains a set distance between the car and traffic ahead.

The Jaguar XK Convertible takes all the virtues of the V8-powered coupe and adds a power-operated ragtop for sky-high enjoyment.
