  • How to Touch-Enable Arbitrary Objects using TDR We demonstrate how to (multi)touch-enable a series of unusual objects, including a headphone cable, a guitar string, a keyboard made from cardboard, a trashcan, the floor, and finally how to paint your own touch interface using conductive ink. The sensing in all examples is based on "Time domain reflectometry", a technology originally developed in the 50's to diagnose cable faults. We have extended the technology to allow touch-enabling thin, modular, and deformable surfaces and devices. We think our approach could be useful for touch-enabling smart clothing and for rapid prototyping touch sensitive objects of arbitrary shape.

  • Fluke Networks TS100 Cable Fault Finder Tutorial Featuring Pro3000 An easy-to-use fault locator, cable and wire manager and tone generator. This easy-to-use, competitively priced tester is three tools in one -- a fault locator, a cable & wire manager and a tone generator with SmartTone™ technology. From just ONE END of any two or more conductor cable you can measure up to 3000 feet (915 meters). Easily find the distance to opens or shorts on electrical wire, telephone wire, security wire and coax. Results appear as a distance reading rather than a waveform, so it's perfect for technicians unfamiliar with Time Domain Reflectometery (TDR). Find and fix cable problems without pulling new wire or blindly cutting into walls. Intermittent faults are easier to find because the unit constantly measures while "On". It's perfect for inventory management of cable stock in trucks and warehouses and it can help you generate more accurate bids for jobs by quickly assessing needs and managing the cable stock with greater accuracy. Patented SmartTone technology gives you 5 distinct tones to use for exact wire and pair identification, even in proximity to current-bearing cable. When touching the wires together and momentarily shorting the far end of a cable pair, the SmartTone technology will change the cadence of the tone generated. This tone change you hear through the probe positively verifies the correct wire pair. Voltage detection in the unit will immediately sound an alarm if you accidentally clip onto an energized pair, up to 250VAC. Available at ...

  • Novel Teflon probe allows the measuring of the moisture even in the toughest adhesive materials With the moisture probe SONO-MOVE Teflon the company IMKO presents a completely new probe for moisture measurement in adhesive materials such as Calcareous lime sand. In addition to the moisture value, also delivers a radar-based conductance value (RbC Radar based Conductance). This enables enables to establish the mineral content in the measured material and consequently ensures an improved quality control. With its special probe design the SONO-MOVE T is ideal suited for installation on conveyors and in silos, containers and hoppers. The material on the conveyor belt is affected only slightly with the wedge-shaped structure. The probe head is made of Teflon and thus providing best possible anti adhesive properties. SONO probes calibrate themselves in the event of abrasion due to a novel and innovative probe design. This consequently means longer maintenance intervals and, at the same time, more precise measurement values. Their secret: The application of the most modern TRIME® radar technology (Time-Domain-Reflectometry). Via an electromagnetic TDR-impulse with a frequency of 1 GHz SONO-probes measure the water content precisely until the material has become saturated, and they continue to measure beyond this stage. In addition, valuable observations can be made regarding the mineral content or the consistency of the material measured. An extremely wide variety of devices can be equipped with SONO-probes and they can be connected to all control systems without any problem.
