Innovation Spotlight

We take an in-depth look at a specific part of the TyRex family  in this innovation spotlight. This time we spotlight a “button pusher” and a “chamber extender”, two innovations being used at Austin Reliability Labs.


What does the “button pusher” do?

Jon Roesch, ARL Lab Technician: The “button pusher” is an electro-mechanical device with similarities to a CNC (computer numerical control) machine. The computer tells the motors to move, and the motion of the motors is changed from rotational to linear motion along the x-y plane of the equipment being tested. Every 300 milliseconds, the computer program tells the pneumatic cylinders to engage – all the while, each of the 16 keys are monitored for actuation. If the key is actuated during this cycle, the software counts the total.


What do you really call this thing, and what problem does it solve?

JR: We call it a button pusher. “Repetitive Keypad Fatigue Test Machine” seems too wordy. It keeps me from having to push buttons 20 million times and keep track of when they fail.


What about the chamber extender?

George Ayad, TyRex Facilities Manager: The lab needed to test a piece of equipment that was five feet long, but our Thermotron chambers only measure three feet squared. The extender allows the lab to test equipment up to seven feet long. It was like building a house – I installed a wood frame, and then filled in layers of insulation. I put it on wheels to make it easier to move and store.


How does it work?

Steve Derrick, ARL Lab Manager: We attach the chamber extender to one of our 32c chambers and place the oversized equipment into it for thermal testing. The chamber extender can handle temperatures from about 70°C to -5°C.

About ARL

Recognized as one of the top product reliability labs in the country with a unique balance of testing, consulting and on-site staffing services, Austin Reliability Labs (ARL) is a place where we recognize the hard work and passion that goes into the design and development of your product and want to find any problems in an effort to perfect it. We also understand a reputation is something that builds over time, so we focus on establishing long-term partnerships with each of our clients. With that in mind, we not only specialize in writing and developing all of the tests that we perform, but, unlike other labs, we provide pass / fail reports on all of our tests and decipher the results for you in order to maximize your product’s success. In addition to our on-site staffing and consulting services, ARL’s full array of reliability testing services include: HALT / HASS, Battery Life Tests, Qualification Tests, Environmental Tests, Mechanical Tests, Additive Manufacturing Tests and Custom Tests.

We believe quality is infused by finding every flaw in a product and methodically removing each one until the product shines. As a result, only a thorough, comprehensive reliability test program, as provided by ARL, will allow a product to emerge that will earn or maintain an unsullied and clean brand reputation.
