NORWOOD, Mass. (PRWEB) October 15, 2008

In keeping with the theme of Convergence 2008, “Vehicle Electronics Converging on Real Customer Needs,”. ADI will demonstrate a series of innovative solutions showcasing car safety, infotainment and sensing electronics. For more information, visit

Automotive Safety Restraint: Although most of today's safety systems are passive, OEMs are moving towards adaptive passive systems. This demonstration features an adaptive safety restraint system reference design developed by Infineon Technologies AG and based on ADI's iMEMS® inertial sensors. Tier 1 safety system suppliers and OEMs can now access a turnkey system solution where all the component interoperability risk has been removed, saving cost and development time.

Vehicle Stability Control: Analogue Devices'. Stability control demonstration incorporates ADI's iMEMS® Motion Signal Processing™ technology to illustrate the application of motion sensing in rollover detection and electronic stability control systems. The demonstration incorporates MEMS accelerometers and gyroscopes to measure rotational movement in the X, Y and Z axes. Then illustrates pitch, roll. Yaw movement using desktop computer animation.

Mixed Signals Opens New European Office | Business Wire

LOS ANGELES--(BUSINESS WIRE)--Mixed Signals, North America’s leading provider of digital content monitoring systems, has announced the opening of a European sales and support office. Mixed Signals is enhancing its European business development efforts to strengthen its position in the rapidly expanding European video services market.

“We are experiencing great success in North America, and we look forward to providing best-of-breed monitoring and service assurance products in the EMEA market,” said Eric Conley, CEO of Mixed Signals. “As television services grow more competitive, both the quality of, and the network for, delivering television signals becomes even more mission critical.”

After an extensive candidate search, Sam Kershaw, formerly vice president of EMEA at BigBand Networks, has been selected to establish Mixed Signals’ European team and directed to focus on the Video Service Provider markets. His experience at BigBand helped Kershaw build a portfolio of customers that included the leading European cable and IPTV companies. “We are confident that Sam will be able to position Mixed Signals as an essential component of any video network...

Multimedia Connectivity: Consumers are demanding compressed audio content that they can listen to while driving and that doesn't require modifications to factory-installed radios and speaker systems. Car manufacturers are reacting to this trend by adding multimedia connectivity to current and next-generation radios. Analogue Devices'. MDI (Multimedia Device Interface) demonstration is a hardware/software solution that allows car OEMs to quickly add compressed audio playback (MP3/WMA) to their audio systems without a lengthy radio redesign. The MDI solution supports various media, including USB sticks and SD cards. Audio streaming from a Bluetooth-enabled cellular phone is also supported. Additionally, the MDI software system contains all required components including device drivers, MP3/WMA audio decoders, CAN protocol stack. A system framework that enables quick additions of application layer software by the car manufacturer.

Automotive Audio Solutions: Today's automotive head units are tasked with the centralized management of many different forms of content coming from CD changers, MP3 players, satellite radios, navigation systems, DVD players, USB hard drives and other storage media. The result is a series of digital input signals coming from many different asynchronous sources and operating at different samples. For this demonstration, ADI's SigmaDSP® audio processors manage these disparate signals through a unique combination of a DSP core, S/PDIF transceiver. As many as eight stereo asynchronous sample rate converters. By providing the right level of performance, system integration and an efficient instruction set, the SigmaDSP product family is part of a highly-flexible audio routeing matrix that simplifies automotive audio system design by enabling easy routeing and processing of digital signals from many different sources.

Automotive Fluid Level Sensing: Automotive fluid level sensor operating environments are demanding, causing durability issues with existing mechanical solutions and driving demand for more robust, higher precision, cost competitive non-contacting sensing solutions. This demonstration illustrates how ADI's capacitance and ultrasonic technologies can be adopted for fluid level sensing. ADI's capacitance technology delivers a complete signal processing solution for level sensing, incorporating electromagnetic compatibility, adaptive environmental calibration, small package, low power consumption and fast response time. In addition, ADI's innovative correlator-based single chip ultrasonic pattern detection technology adds a new dimension to the performance of ultrasonic sensing, enabling its implementation in mainstream automotive applications such as oil level sensing. Compared with conventional approaches, the correlator-based technology is independent of amplitude, offers a superior SNR and can transmit more power using longer patterns without resolution losses. This results in a higher precision, more robust, lower power, cost competitive solution.

HEV Battery Monitoring: The safe and reliable operation of a Li-ion-based battery stack requires that each cell voltage be accurately monitored and balanced as needs dictate. In addition, other parameters such as cell temperatures and stack current are required by the battery management unit. This demonstration, which highlights the comprehensive functionality of ADI's AD7280 Li-ion battery monitor, also features the AD8210 current sense amplifier to measure stack current. ADI's iCoupler® technology, which is used to isolate the high voltages of the stack from the low voltage electronics that follow.

Wireless Router Vs. Modem

Routers and modems are two networking devices, which play a central role in making Internet access possible. Many new Internet users get confused between them.

How are They Different?

In actuality, a modem and a router, are not directly comparable, as the roles they play are quite different. So, the choice is not between the two, as they are not mutually exclusive.


The term 'Modem' is actually an acronym for 'Modulator-Demodulator'. This electronic device converts digital signals to analog and analog signals, back to digital form. When you have a cable-based or phone line based connection, the data packets are transmitted over a cable in analog form, which needs to be converted to digital format, for the computer to process. This function is carried out by the modem. It establishes the link with the Internet service provider (ISP) and handles the data transfer, to-and-fro, from the ISP server.

A wireless router is a device that facilitates the integration of multiple computer networks and provides Internet access to computer terminals, through a radio link. It is a wireless transreceiver, attached to the modem on one end and connected with various computer terminals, through a radio frequency carrier link, to provide wireless Internet access. So any data to be transmitted on a network, first arrives at the modem, where it is modulated into a digital signal and then transmitted on a radio carrier signal, by further modulation, via a router.


Modems are differentiated by the amount of data they can transfer per second. Depending on the transmission medium used for transfer of data packets, different modems are used. For example, an ADSL (Asymmetric Digital Subscriber Line) modem is used to modulate and demodulate data over a copper phone line. Many modems are now built with an integrated router, which performs the function of both devices. Choose a...
