Within the last few years, designers have established a solid powertrain foundation for hybrid vehicles (HEVs) and electric vehicles (EVs). All major auto manufactures see the hybrid and electric vehicle market as one continuing to enjoy steady growth. One major driving factor to the projected increased growth is the significant technology advances taking place that directly impact the HEV and EV power electronic systems.
By Kerry Johnson, QNX Software Systems Already, vehicle telematics services have been deployed in tens of millions of automobiles. Nonetheless, mobile services offered on smart phones and other consumer devices are growing at a far greater pace. A quick survey of these mobile services reveals that many offer significant utility to drivers or passengers; in fact, some are designed specifically for in-vehicle use.
By Chris Keeser, Cypress Semiconductor Corp. The other day I was driving to the local dump to drop off a load of trash carefully stacked into the back of the family minivan. Suddenly I noticed that the “trunk open” light came on. I quickly pulled over just as the rear hatch popped all the way open and the van began to empty my garbage bags all over the road.
By Ashish Sharma, Alvarion Ltd. Imagine having the ability to unify all the communications needs for the smart grid via a single communication – be it distribution automation, concentrators, video surveillance, smart metering, mobile workforce, etc.
The future holds RFID Applications that go far beyond mere bar coding. The world will be a different place once readers and RFID tags are everywhere. Q: “What are some of the untapped applications for RFID that we may see in the foreseeable future?” By Victor Vega, Alien Technology UHF RFID has matured to a point where “it just works.
There is a lively debate going on among scientists over whether technology’s influence on behavior and the brain is good or bad, and how significant it is. Scientists say juggling email, phone calls, and other incoming information can change how people think and behave.
Multiple antenna technology enables high capacity and high data rates. Q: Right now there is a limitation on data rate for each user. Can MUMIMO overcome these limitations and if so, how? J. McFarland, Chief Technology Officer for Atheros Communications The advent of Web-enabled phones has clearly pointed out that wireless carriers need more system capacity to meet the expectations of their users.
By Joe Cozzarelli, ANADIGICS As mobile carriers and network operators transition to 4G service, they are faced with several challenges, including the massive amount of smartphones available in the market, the volume of data traffic per phone that is rising exponentially, and all the steps required to deploy and upgrade their network infrastructures.
The growth of features available in mobile phones has both driven and been enabled by changes in NAND based memory architectures. As phone capabilities evolved, feature rich phones migrated from NOR-based solutions to NAND-based solutions. Today, with the growth of GB1 (Gigabyte) class phones, a variety of NAND-based architecture solutions are available with various tradeoffs to consider.
In the operating environment seen by electronics today there are numerous sources of electromagnetic interference (EMI) and radio frequency interference (RFI). This is due in large part to the increased use of RF technology. These types of interference result in the need for common mode filtering in applications utilizing differential interfaces.
Dr. Robin Tichy, Micro Power Electronics Li-ion cells come in three basic form factors: cylindrical, prismatic (rectangular brick shape) and the flat Lithium polymer cells. Lithium polymer cells, sometimes called laminate cells, are available in custom footprint size. They can be very thin or quite large depending on their intended use.
Third- and fourth-generation wireless base stations that use today’s most-common interface standards, such as WCDMA, TD-SCDMA, LTE, TD-LTE and Wimax, require a large amount of signal processing to keep up with the uplink and downlink bandwidth requirements.
The Electronic Frontier Foundation (EFF), a non-profit organization that was founded in 1990, and champions on behalf of consumers regarding any issues affecting digital rights, recently won three critical exemptions to the Digital Millennium Copyright Act (DMCA) anti-circumvention provisions.
Q: Right now there is a limitation on data rate for each user. Can MUMIMO overcome these limitations and if so, how? William J. McFarland, Chief Technology Officer for Atheros Communications The advent of Web-enabled phones has clearly pointed out that wireless carriers need more system capacity to meet the expectations of their users.
It wasn’t all that long ago that Multiple-Input Multiple-Output (MIMO) technology first captured the cellular industry’s attention by promising higher data rates for a single user using two or four streams of data transmitted (and received) with multiple antennas.
