Everything from the choice of logic blocks to the routing segmentation is influenced by these switches. SRAM switches provide the possibility of reprogramming the device. However, this feature comes at a prohibitive price: large area and reduced performance. Unless the reprogrammability of an FPGA is an absolute requirement, the antifuse based FPGAs provide a better solution to the switching requirements inside an FPGA. In most design environments, the cost of implementing a design on an FPGA is not dominated by the unit cost of the FPGAs programmed in the development phase. The dominant cost is the engineering time spent on achieving performance goals and the risks involved in not reaching the market on time.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126962715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All portable equipment draws its operating power from a battery pack and more often than not these are constructed from rechargeable cells. A single charger design may required to recharge packs of varying capacity or even different chemistries. In many cases this means the charger is designed to recharge packs in a manner which is suitable for any pack option which may be presented to it-thus sacrificing performance for safety. The design of smart battery electronics encompasses much more than simply defining data and communication standards to be adopted by the user community. Any device proposed for this application should satisfy the practical requirements imposed by factors such as ESD and interconnect cost. The devices presented are optimized for this application in those respects as well as offering a variety of feature and packaging options to meet-the need of nearly any battery pack design.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127040968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Temperature termination and the thermal characteristics of NiCd and NiMH batteries 镍镉电池和镍氢电池的温度终止和热特性

As the battery reaches full charge, the internal cell temperature rises dramatically. Detecting this temperature increase can be used as an effective method of terminating charge to a battery. Temperature termination is an excellent approach assuming constant current cannot be used, and providing that any problems involved with sensing temperature accurately and reliably are taken into account. Nickel-cadmium and nickel-metal hydride batteries heat differently during charge, but both chemistries display a rapid increase in temperature as they enter overcharge. The rapid increase in temperature can be used to signal the onset of overcharge. However, every sustained rise of 5/spl deg/C in temperature at high charge rates will cut battery lifetimes in half as a result of subjecting a battery to repeated overcharging. Therefore, the temperature rise must be kept as small as possible. Thermistors can be used as a temperature sensor in such circumstances.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132685335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Federal Communications Commission (FCC) is in the final phases of testing the transmission protocols and image compression. The new standard is to be based on the MPEG-2 standard which is supported by a consortium of large corporations. However a question remains, whether the new standard will be a success or a dud like the Japanese MUSE standard was a few years ago. As it turns out, the new standard is based on very old and already superseded technologies. Even if the new TV is eventually made to work, it will produce images with barely tolerable distortions, while being very complex, expensive and hard to maintain. An emerging \"Lossless\" image compression scheme, based an autosophy networks and a new \"Information Theory\", may provide a better solution. Communications bandwidth will no longer depend on image size, resolution or frame rates, but rather only on the content of the images. Software simulation experiments have produced very promising results by combining high \"Lossless\" image compression with superior operating characteristics.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124226098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
