Software related inventions being not simply excluded from patenting — as confirmed by the recent amendments of the EPO Guidelines — the question arises whether DG1 should adapt its search documentation in order to enable such inventions to be properly searched.As a matter of fact, the question concerns only the non-patent literature (NPL), mostly articles from journals and conference proceedings, because these documents are only selectively classified for inclusion in the search documentation — whereas patent documents are all systematically classified and included — and besides, software matters are rarely dealt with in the present patent literature. In view of the foregoing, the paper illustrates the importance of non-patent literature for search purposes and considers the selection criteria for articles and for the collection of technical journals. 相似文献

对话音质量的评断往往非常主观,而“用户平均评价记分(MOS)”方法则能提供一个较为客观的评价,休斯网络系统(HNS)的GMH2000固定蜂窝系统获得了极高的MOS,这意味着该系统提供的话音品质很高。本文介绍了影响固定蜂窝系统话音质量的一些关键因素,对模拟和数字数字蜂窝系统的MOS评价作了比较,最后简述了GMH2000高话音品质的原因。 相似文献

NTT DoCoMo的国内外战略 总被引:1,自引:0,他引:1
NTT DoCoMo是日本最大的移动通信公司,主要提供2.5G的i-mode和3G的FOMA服务。DoCoMo在国内的战略是将i-mode构建成开放式的移动网络;实现一步到位的3G战略,推出价格便宜的FOMA服务。但由于准备不足,DoCoMo在推进FOMA服务时出师不利。DoCoMo在进军国际市场时注重了地域及合作伙伴的选择。 相似文献

Power supply problems worldwide are not only due to the depletion of conventional energy resources but also due to continuously increasing consumption. This overloads both distribution grids and power stations which has serious consequences on power availability, security and quality. Consequently, solutions are needed which are technically feasible and match the conditions of sustainability. G. Cramer, M. Ibrahim, and W. Kleinkauf describe the current state-of-the-art and perspectives of Solar PV as a solution in grid-connected and decentralised power supply structures. 相似文献

Since the first Chinese Patent Law was promulgated, the Chinese Patent Office has been trying to establish its search files. It learned from some good experiences abroad and took its own concrete situation into consideration. A scientifically arranged and practical documentation system is expected. 相似文献

In the Fall of 1991, after approximately two years of development, the department of Electrical and Computer Engineering (ECE) at Carnegie Mellon University (CMU) implemented a new curriculum that differed radically from its predecessor. Key features of this curriculum include: Engineering in the Freshman year, a small core of required classes, area requirements in place of most specific course requirements, mandated breadth, depth, design, and coverage across ECE technical areas, a relatively large fraction of free electives, and a single integrated Bachelor of Science degree in Electrical and Computer Engineering. In this paper we review the design of this curriculum, including a taxonomy of problems we needed to address, and a set of general principles we evolved to address them. The new curriculum is described in detail, including new data from an ongoing analysis of its impact on students' curricula choices 相似文献
