	Spotlight Story: What's a TDC, Anyway? When engineers think of an analog-to-digital converter (ADC), they usually need to measure a voltage or current. But, you may need to measure another analog quantity: time.

In the News: Trillions of Sensors Could Soon be Looking for Data Connections Beyond the familiar world of IMing and email is a much larger and rapidly growing world of machine-to-machine (M2M) communication links, which could include trillions of individual sensors by 2010. Full Story Year of the Mixed Signal Complexity begets a response as test vendors get on the mixed signal oscilloscope (MSO) bandwagon, providing analog and digital channels in a single testing device. Full Story Synthetic Instrumentation Comes of Age The concept is simple: Harness basic sensors and then add the traditional functionality of an instrument through software on a generic platform. Full Story A Look at the New GenICam Camera Standard A product of the European Machine Vision Association, the GenICam programming interface has since spread worldwide. Full Story “Industrial” USB? Some say the ubiquitous PC interface offers many advantages for data acquisition jobs. Full Story ADVERTISEMENT Batteryless Operation A SAW transducer combined with RFID is only one of the techniques being used to eliminate batteries. Another approach for energy harvesting uses a miniature coil and an externally applied alternating field eliminating the need for batteries in an artificial knee. Do you have an application that could be a candidate for batteryless operation? If so, what is the application? Post a Reply Have a design problem?

ADVERTISEMENT The Latest Electronics/Test Resources Available: Featured Vendor RDP Electrosense New from RDP is the low-profile DR7AC carrier amplifier, designed to provide excitation and signal amplification for LVDTs and other inductive transducers. The DR7AC is compactly packaged for DIN rail mounting, which will prove the benefit to systems integrators and machine builders. View All Resources From RDP Electrosense USB Moves Into Industrial Applications National Instruments | Software A decade ago, the introduction of Ethernet on the factory floor was met with considerable skepticism. Engineers raised questions about its communication reliability, connector performance and hardware sustainability under harsh industrial environments. Ethernet evolved to overcome these concerns, and engineers are now successfully using it in a variety of industrial applications from mining to offshore drilling. Now, with the explosive growth and adoption of USB in the PC industry, engineers are evaluating the viability of USB in industrial environments. NI Signal Streaming: Sustaining High-Speed Data Streams on USB National Instruments | White Paper To optimize the use of the Universal Serial Bus (USB) and deliver high-performance data acquisition, National Instruments created NI signal streaming technology. This white paper describes the challenges associated with high-speed data acquisition on USB and reasons why NI signal streaming technology is essential to any USB data acquisition (DAQ) device.
