1. 2.4-GHz Radio-on-a-Chip
Cypress Semiconductor Corp. today introduced the world's first 2.4-GHz Radio-on-a-Chip with a programmable mixed signal array. Cypress's new Programmable Radio-on-a-Chip (PRoC) includes two of the company's most noteworthy technologies - WirelessUSB and Programmable System-on-Chip (PSoC) - in one integrated device.
WirelessUSB has seen dramatic growth due to its ease of use and installation, low cost, and outstanding interference immunity. Systems with WirelessUSB also require a mixed-signal array or microcontroller for control functions. The new PRoC device is the first in a broad portfolio of devices that combine WirelessUSB technology with Cypress controller solutions. PRoC offers access to a general-purpose mixed signal array with four programmable analog and four programmable digital blocks, 8K Bytes of Flash program memory storage, 512 Bytes of SRAM data storage, and a powerful Direct Sequence Spread Spectrum (DSSS) 2.4GHz radio system - all integrated in a compact, 48-pin QFN package. It is designed to implement highly-integrated, space-saving, low-cost, wireless systems operating in the worldwide 2.4-GHz ISM band.

2. Educational Game Console Development Kit
Nurve Networks LLC's new XGameStation Pico Edition educational game console development kit is now shipping worldwide. The Pico Edition is a follow up to the previously released pre-assembled XGameStation Micro Edition. The Pico Edition is for students and hobbyists that actually want to build the system by hand from a kit of parts. The Pico Edition comes as a kit complete with a solderless breadboard and all the components to build an entire working game console in about 1-2 hours.
The Video games industry generates billions of dollars in revenue each year. In addition, game programming books occupy rows of bookstore shelf space. Video game development has made its way into college curriculums and entire game programming universities have emerged. The XGameStation Pico Edition (XGS PE) is a complete game development kit inspired by classic systems such as the Atari 2600, 800, Apple II, C64 and Nintendo Entertainment System. The XGS PE kit includes a kit complete with all the parts, necessary cables, an eBook written by Andre LaMothe on the design and programming of the XGS Pico Edition along with all the software necessary to create your own games, demos, and experiments.
The official Website for the XGameStation is http://www.xgamestation.com/?refid=pr, where you will find Media, Downloads, Demos, and more information on purchasing the XGS Pico and Micro Editions.

3. DSL reaches 107 million subscribers
The 25 countries of the European Union added 4.18 million DSL subscribers in the first quarter of 2005, reaching a total figure of more than 35.6 million subscribers. Accounting for almost a third of DSL lines makes Europe the world's leading region for DSL lines, according to the latest figures from market research group Point Topic on behalf of the DSL Forum. Looking at a worldwide scope, DSL notched up over 10 million new subscribers during the first quarter of 2005 to reach 107 million, cementing its position as the most popular broadband technology. In the U.S., DSL increased its share of the broadband business, with 1.37 million subscribers added in the first quarter of 2005, the second largest subscriber increase worldwide. The UK added more than 840,000 subscribers in the same period, bringing the total figure to almost five million. As of March 31 2005, China remained the country with comfortably the largest DSL population worldwide, with 2.5 million users added during the first quarter. Its 19.5 million subscribers account for 95 percent of the total subscribers in South and South East Asia.

5. Maintenance free regulated lead-acid batteries
Panasonic has extended its range of batteries with nine new batteries for industrial use. Thanks to the AGM technology, these batteries are distinguished by being absolutely free from maintenance, having extremely consistent technical parameter performance and long life. They are available as 12V models, with capacities ranging from 2.2 to 120 Ampere-hours (Ah) and a 6V model delivering 135 W for the demanding high current sector.
The VRLA batteries work with an absorbent electrolyte system. The entire electrolyte is bonded into the positive and negative plates, as well as into the fiberglass separators. The use of special sealing resins, a grooved housing cover and long sealing ducts for the terminals guarantee the absolute minimal self discharge, and also enable the battery to be used in any position. The protection against gas forming in normal operation affords additional safety.
Neither do they require any maintenance. This means there is no need to check the specific gravity of the electrolyte or top it up with distilled water. They simply require charging. The models even withstand over charging and total discharge, vibration and shocks better than comparable batteries.

6. Teamwork in fuel cell technology
Fraunhofer Institute for Solar Energy Systems ISE in Freiburg, Germany and The Fuel Cell Center of the University of South Carolina (USC) signed a Memorandum of Understanding concerning fuel cell and hydrogen research. Both partners are leading institutions for applied research on fuel cell technology in their respective countries. The development of miniature fuel cell systems and hydrogen generation is a main focus at Fraunhofer ISE. The Fuel Cell Center of USC is the only "Center of Excellence" in the National Science Foundation which is devoted to fuel cell research in the USA. The German and American partners agreed to co-operate closely on research, to acquire research projects jointly and to market patents together. They intend to concentrate on fuel cell development, and hydrogen generation and storage.
