Ohmite : Current sense resistors have 1 percent tolerance Product News 3/30/2009 Post a comment Using metal resistive elements made from Nickel-Chromium or Cupron (Manganin-Copper) the MCS Series of SMD flip chip resistors from Ohmite have a very low TCR of <50 ppm/°C over the range of current sense values which are popular in portable, battery operated equipment and power supplies.
Watch out Heidi Klum, here comes the HRP-4C! Industrial Control DesignLine Blog 3/27/2009 Post a comment A very interesting development in the world of robotics as the HRP-4C fashion model is introduced to the world at Tokyo's Fashion Week. This modern marvel of sensors, motors, and controllers, responds to voice commands, walks, talks, and even has motors controlling facial expressions. But is the research and development effort worthwhile?
Mobile operators seal, extend network sharing deals News & Analysis 3/23/2009 Post a comment In a wide-ranging cost cutting deal that will have major implications for their equipment suppliers, and further down the chain for many component suppliers, Vodafone and Telefonica have confirmed they will pool their mobile networks in the U.K and said that the deal covers several other European countries.
The AspireRfid Project Design How-To 3/16/2009 Post a comment RFID middleware is gradually becoming a cornerstone for non-trivial RFID deployments. John K. Soldatos and Didier Donsez provide insight into why this is true in complex heterogeneous environments comprising multiple readers, applications instances, legacy ICT systems, as well as sophisticated business processes and semantics.
Analyst: Top chip suppliers are underperforming News & Analysis 3/11/2009 Post a comment Almost all of the semiconductor industry's top 25 companies not only saw sales declines last year—they also underperformed the overall chip industry for the year, according to researchers at iSuppli (El Segndo, Calif.)
Tire pressure monitors to reduce CO2 emissons News & Analysis 3/10/2009 2 comments The European Parliament Tuesday (March 10) passed a proposal that will make tire pressure sensors for new cars mandatory. The industry is prepared to offer the technology required but new developments enhance the scope of options.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
