Energy Metering MCUs

Atmel(R) Corporation (San Jose, CA) has expanded its Atmel | SMART portfolio of energy metering products with the introduction of the SAM4C32 dual-core secure MCU, along with the SAM4CMS32 and SAM4CMP32 for residential, commercial and industrial metering applications. The new system-on-chip (SoC) solutions have 2MB of cache- enabled dual-bank flash and are pin-pin compatible with existing 512KB and 1MB devices in the portfolio. Atmel's SAM4Cx series are built on a dual-core 32-bit ARM(R) Cortex(R)-M4 architecture with flexible firmware metrology capability up to a class 0.2 accuracy designed to meet WELMEC requirements for the separation of legal metrology, applications and communications.

Protocol Analyzer

Keysight Technologies, Inc. (Santa Rosa, CA) has introduced the U4301B PCIe(R) protocol analyzer for engineers developing PCIe Gen3 systems. The U4301B supports all PCIe speeds from 2.5 GT/s (Gen1) through 8 GT/s (Gen3) and link widths from x1 through x16. The analyzer comes standard with analysis tools to validate PCIe LTSSM (link training and status state machine) processes, as well as NVM (non-volatile memory) Express and AHCI (advanced host controller interface) transactional protocol operations. New interposers support the latest storage devices that use SFF-8639 and M.2 connectors. The U4301B PCIe analysis module works in an AXIe chassis. For more information, click here.

Why bigger isn’t always better: the case for thin section bearings

For applications that demand maximum performance despite space and/or weight restrictions, designers should consider thin section bearings. While conventional bearings often have more load capacity, thin section bearings have more than enough for a wide range of applications and offer exceptional design flexibility with opportunities for significant reductions in overall system size and cost. A new white paper from Kaydon Bearings, an SKF Group company, examines thin section bearing styles and features, with a discussion of design considerations, fit, lubrication, and other useful information.

Ultrasound Creates 3D Haptic Shapes

Touch feedback, known as haptics, has been used in entertainment, rehabilitation, and even surgical training. University of Bristol researchers, using ultrasound, have developed an invisible 3D haptic shape that can be seen and felt.Led by Dr Ben Long and colleagues Professor Sriram Subramanian, Sue Ann Seah, and Tom Carter from the University of Bristol’s Department of Computer Science, the research could change the way 3D shapes are used.  The new technology could enable surgeons to explore a CT scan by enabling them to feel a disease, such as a tumor, using haptic feedback.By focusing complex patterns of ultrasound, the air disturbances can be seen as floating 3D shapes. Visually, the researchers have demonstrated the ultrasound patterns by directing the device at a thin layer of oil so that the depressions in the surface can be seen as spots when lit by a lamp.The system generates an invisible three-dimensional shape that can be added to 3D displays to create an image that can be seen and felt. The research team have also shown that users can match a picture of a 3D shape to the shape created by the system. SourceAlso: Learn about an Ophthalmic Ultrasound System for Ocular Structures.

Key Factors to Consider When Determining the Best Curing Technology for your UV Assembly Process

Manufacturers are under constant pressure to reduce costs and improve efficiencies within their manufacturing processes in order to increase profitability. With recent advancements in LED technology, new possibilities open up and a growing number of manufacturers are considering switching from lamp to LED technology for their UV processes. Lamp technology still has advantages in certain applications, as there are benefits and limitations to both technologies depending on the specific application. This webinar will discuss the factors to consider when determining whether lamp or LED technology is best suited for your application and how each technology can be utilized in a well-developed UV process to ensure repeatable product assembly.
