ing). Each switch from one task to the other takes time, perhaps a few tenths of a second. A driver must constantly scan


his environment and react. We tend to think we are able to see everything ahead of us. In reality, the brain deals with one item — a branch fall- en on the road ahead, for example — at a time. To deal with the branch, the brain: l

The Huntron Access DH Prober is designed with your test and measurement needs in mind.


Te Access DH dual head Prober lets you control variables such as dexterity, high density, tight lead spacing and speed with precise, fast and repeatable guided probing.

brain then: l l


Retrieves the information.


Acts on the information. What happens when you are try-


ing to multitask by talking on a cell phone and watching the road? As you switch back and forth from one task to the other, some of the incoming infor- mation is dropped even before the first four steps are completed. Your eyes initially “see” something, but the infor- mation doesn’t quite “register.” The overall effect is that the dri-


ver’s vision is, in practical terms, greatly impaired. When not using a cell phone, you will see the road ahead for hundreds of feet, and you will see significant items to the left


and right, such as a car approaching on a side street. When you are using a cell


phone, your real vision encompasses the road straight ahead and not much else. The road ahead is seen and processed only for a limited dis- tance. Items off to one side are “seen” but not processed. Signs off to the side are “seen” but not recalled or acted upon. That car coming down the side street and about to blow the stop sign is effectively invisible.


Missing Information The truly dangerous part of this


scenario is that the driver is not aware that some information is being dropped. He doesn’t know which in- formation is not being encoded and stored. There is nothing to tell him that he is cognitively distracted. A Carnegie Mellon University


study reported in the NSC paper placed drivers on a driving simulator and asked them to answer questions on a cell phone. Activity in the subjects’ parietal


lobe, important for driving, dropped 37 percent. Activity also dropped in the brain’s occipital lobe, which processes visual information. And a University of Utah simulator study showed that drivers on cell phones had slower reaction times than driv- ers whose blood alcohol level was a legally drunk 0.08 percent. r

Te ability to customize the Access DH probe head assemblies combined with software created using the Huntron Workstation SDK, Hardware SDK or Remote Control provides many integration and customization opportunities. Te probe head design includes pre-wired interconnections for adding built-in USB, Firewire or Ethernet instrumentation at the head.

Test Automation


As the density and complexity of circuit boards has increased, the need to accurately place a probe on a test point has grown. Huntron recognized this issue early on and released its first robotic test platform in 1991. Our Access Probers have matured over the years with increased accuracy and the ability to be customized based on your test and measurement needs.


nately for photovoltaic (PV) bus bars and other applications such as anten- nas, flexible connectors, and smart packaging, will account for $2.3 Bil- lion for the ink alone. This excludes the cost of conductive ink for shield- ing/static discharge applications and membrane circuits, where the sectors are already mature. Almost all of this is flake-based ink. In addition, almost $2.6 Billion


will be spent on CIGs based photo- voltaics in 2012, but almost all of this is non-printed and on glass. However we include this as part of the big picture because there is sig- nificant effort pursuing printing to manufacture CIGs.

OLED display market will rise to $30 Billion in 2022, and of that 20 percent will be predominately print- ed and 17 percent on a non-rigid sub- strate. Indeed, significant research and investment in printed OLEDs is happening now, and with Samsung’s decision to spin out its LCD business and focus on OLEDs, we can expect the use of OLEDs to accelerate com- pared to what been slow growth un- til a few years ago. OLED lighting will become a $1


billion market by 2019. OLED light- ing panels need to scale up in size to reduce cost and meet the competition from LED lighting which is now huge- ly successful in lighting markets across the board. In addition, there are serious new technical develop-


ments, such as printed LED lighting. Printed Batteries Sales of printed batteries, logic


and memory remain very small, but some areas are starting to come to- gether. This includes the creation of useful “building blocks” in the form of memory addressed by printed transistors, and now combining that with sensors which have applicabili- ty to a wide range of markets, and moves away from those trying to sell a transistor to those having a useful product to buy. While metal flake ink is predominately used today for screen printing PV bus bars, there is growing interest in using inkjet printable ink in order to reduce the risk of breaking the ever- thinner sil- icon PV cell by having a non-contact deposition method. Particle-free metallic ink, graphene-based inks and copper are now in development or commercial use in a number of ap- plications that include tamper and theft monitoring of retail packages. Indium Tin Oxide (ITO) is still


more than 95 percent of the $3.5 bil- lion transparent conductive film market. Indium is subject to supply restriction and its price has varied by an order of magnitude in the last ten years. It is required primarily for photovoltaics, displays and touch screen applications, which are enor- mous markets. Alternatives to ITO include transparent organic materi- als, finely printed conductive grid meshes and other ways of patterning metal “strands”. Some even use cop- per rather than silver to reduce cost. Others are investigating carbon nan- otubes and graphene as viable alter- natives and companies with differ- ent technologies are beginning to make some inroads, particularly in touch-screen panel applications.
