Beautiful yet Tough

Part 1: Outline

Portable Devices, Now used Everywhere, Have to be Tough

In the field of portable devices such as cellphones, digital cameras, and laptop PCs, the number of "tough" models with robust characteristics such as water and shock resistance is increasing rapidly. More than merely tough, however, size- and thickness-reduction technologies have made these devices equivalent to regular versions in terms of functionality and external appearance, as well.The addition of toughness though has expanded the application scope of these devices, which in turn is creating new needs and triggering the introduction of new technologies.

Part 2: Design Concept

Different Types of Toughness, Carefully Tailored for Each Device Depending on the Application

Toughness requirements differ for individual devices. Device makers are not haphazardly adding the same ruggedness characteristics to all their products because water- and shock-resistance requirements differ depending on the device. In other words, the appropriate ruggedness characteristics must be added to suit specific applications, along with compact size and light weight.This means that there is no room for design compromise. Only those devices possessing the proper ruggedness will survive as true portable devices.

USB 3.0 Debuts: Connecting Devices at 5 Gbps

It is estimated that 2.6 billion USB (Universal Serial Bus) ports are shipped globally every year.The USB interface has become the standard in a wide range of devices, including personal computers and cellphones.Eight years following the introduction of the present version, the next-generation USB version will be launched soon.Transfer speed will jump by 10 times from the current version, entering the realm of gigabits/sec. This launch may spawn an entirely new class of USB-based devices.USB may again begin to eat into the market of other interfaces such as HDMI (High-Definition Multimedia Interface).

LSIs for Bluetooth: Focus on Combo Chips and Low Power Consumption

Products to Support Wireless Communication for Everyone

At long last, the use of Bluetooth is beginning to spread in Japan, mainly driven by game machines and in-vehicle devices. Behind this development is the fact that Bluetooth has become a general-purpose technology, easily used even by those who know nothing about wireless communication. For those considering the use of Bluetooth devices in the near future, product types that are integrated with wireless LAN or offer low power consumption may soon become options.

Key Points of A-D Conversion Everyone Should Know: Part 3

Continuing from the previous article, this one compares the various performance features of ΔΣ and serial-comparisontype A-D converters. This article focuses on the concept of start/stop in ΔΣ-type data conversion, which confounds many engineers; the size of current consumption; and the high level of expandability.It goes on to describe application examples that once used the serial-comparison type but are beginning to convert to the ΔΣ type.

Designing Proper Electromagnetic Compatibility on Printed Circuit Boards(Second Half)

When designing an electronic device, one must consider electromagnetic compatibility (EMC). To minimize effects on delivery time and cost, EMC must be taken into account beginning with the printed circuit board design. This article describes the specific items of which the designer must be aware.

Cover Story SSDs Challenge HDDs, but Quality a Problem

Solid-state drives (SSD) using NAND Flash memory are beginning to show up in a variety of equipment as storage devices. Prices are dropping as semiconductor technology continues to evolve, accelerating adoption of the drives, but manufacturers must also deal with eroding quality.

Analysis Expanded Use of Silicon Tuners Transforms Tvs

With analog television broadcasting slated for the axe in about two years in Japan, TV broadcast tuners are evolving rapidly, replacing old radio frequency (RF) analog circuits with new integrated circuits (IC) called silicon tuners. Signal demodulators are evolving with them, and by tracing the direction of their evolution it is possible to delineate the shape of tomorrow's TV.

Convenience Stores Lead in Energy Conservation

Convenience store franchises are moving to slash energy consumption following the revision of the Japanese Act on the Rational Use of Energy, and are rapidly becoming showcases for cutting-edge energy-conservation technology. The technologies honed here will spread to other firms in the distribution industry, office buildings and more, eventually worldwide.
