Double-Sided Press-Fit Contacts for Mezzanine Applications

ERNI Electronics (Midlothian, VA) offers a portfolio of connectors from its unshrouded header system series (STL family). The singleor double-row versions are available in many different connection lengths and termination types including press-fit, dip-solder, THR, as well as right-angle versions. These male multipoint connectors are based on 0.025" × 0.025" pin standard and can be combined with a variety of compliant products. Suited for use in mezzanine circuit boards that require unshrouded headers with a 0.100"(2.54-mm) pitch and stamped press-fit zones on both sides, the connectors eliminate the need for a cable connection or an indirect connector link.

UDE 2.0.7 and UAD2 Debug Tools for Microcontrollers

A debug tool specially tailored to support the individual features of Infineon’s new scalable XC2200 microcontoller family was recently released by PLS Development Tools (San Jose, CA). Infineon used the modular components-based Universal Debug Engine (UDE) 2.0.7 and the Universal Access Device 2 (UAD2) family of units from PLS to test its first XC200 microcontrollers and for preparation of software drivers and application examples. Both the UDE 2.0.7 and the UAD2 provide unlimited support for all internal debug resources and peripheral sets of Infineon’s new XC200 microcontrollers. The integrated FLASH/OTP programming function of the UDE 2.0.7 enables high speeds in the entire FLASH, but also for external devices from AMD, Intel, ATMEL, and other JEDEC-compatible FLASH memories.

Encapsulated Video “Brick” Bolsters Video Surveillance Along Boarder

Increasingly dependent on continuous video monitoring and recording, even today’s more sophisticated security surveillance systems are often plagued by reliability problems. In some ways, more complex video systems are susceptible to signal and other dependability problems simply because they are multifaceted. Systems integrators may know what cameras and recorders to use in a given situation, but they also need to consider how subcomponents could play a critical role under certain conditions. A noisy switch or incompatible distribution amplifier (DA) can compromise the integrity of a video security system yet go undiagnosed or even undetected until the horse is already out of the barn.

Secure Your Embedded Wireless Network

Connecting devices like medical instruments, weigh scales, printers, sensors, and other embedded devices to wireless networks allows the user to gain unprecedented freedom and mobility without the need for cumbersome cabling. Traditionally, many of these devices have been confined to a certain area, and the applications have been prone to human error when used by someone to manually collect information and then transfer it to a computer.

Next-Gen Networks Drive AdvancedTCA Deployments

The evolution of technology and the never-ending thirst for higher bandwidth from industries and applications are pushing the limits of existing standards. The latest processors run faster and integrate more features, thus requiring greater power, more efficient cooling design, and a larger board size. The explosion of bandwidth in enterprise local-area networks (LANs) brought on by the deployment of gigabit Ethernet, 3G/WiMAX mobile communication, and wireless network systems and the growth of triple-play or multi-play network services, have all fueled the demand for servicing greater amounts of data traffic.

Embedded Security: Down to the Silicon

Embedded applications are increasingly going online. With the introduction of new embedded technologies that utilize a wide variety of communications options from Ethernet to Wi-Fi and ZigBee, there is a pressing need to secure these applications against the same problems that are inherent in any networked application.

Monolithic Diffraction Grating Arrays Enable Wide-Bandwidth Single-Shot Spectrometers

For the last forty years, manufacturing technology for diffraction gratings has not changed significantly. Mechanical ruling and interferometric (holographic) exposure have been the two predominant approaches used to fabricate gratings. Both approaches provide limited freedom in terms of the complexity of grating lines (spacings and curvatures) that can be written.
