奥林巴斯E-330
E-330是全球首款可通过后嵌式液晶显示屏提供实时影像取景功能的可互换镜头式数码单反相机。这一技术到目前为止在业界仍被看作是很难实现的,而E-330通过为液晶显示屏安装专用CCD传感器来实现,该传感器与成像传感器相分离,位于类似奥林巴斯E-300中所应用的侧反式取景光路上。此外,我们采用了在奥林巴斯E-500上广受赞誉的项级25英寸超晶液晶显示屏,并配备一个可翻转结构,这样,显示屏在水平轴上可进行翻转,令实时取景所提供的拍摄自由度达到最大化。而且为了确保近距离拍摄时的实时取景能力,E-330采用了全新开发的4/3标准、750万像素Live MOS传感器作为成像传感器。 相似文献

2010年上海世博会的成功举办,让全世界都把目光投向这里。在开幕式上,黄浦江边那巨大的LED屏幕让很多人赞不绝口。这块长300米、高30米、总面积超过9000平方米的显示屏,是目前世界上最大的户外LED显示屏。它炫动的图案和唯美的焰火一起给人们留下了难以磨灭的记忆。此外,世博园广场边、馆壁上也随处可见大大小小的LED显示屏。正是这些显示屏的有效利用,展示给人们一幅幅美轮美奂、变幻莫测的世博景观。世博会作为世界技术展示的最好舞台,同时也成为了LED的最大秀场。 相似文献

An experiment was used to test memory for two forms of information—ad copy (persuasive) and consumer information (nonpersuasive) presented in print and screen media. For both forms of information, print outperforms screen on recall but not on recognition. The results suggest that print information is easier to retrieve but also that screen information is available in memory. Differences between print and screen media are persistent and not readily explained by any of the obvious individual factors—comfort/familiarity, preference, and reading time. Other results with implications for marketing communication decisions show that brand name is poorly recalled from the screen relative to the printed page and that the nonpersuasive consumer information is better remembered than is persuasive ad information. © 2005 Wiley Periodicals, Inc. 相似文献

体验营销与广告标语 总被引:2,自引:0,他引:2
陈海花 《商业经济(哈尔滨)》2005,(4):77-79
市场营销是一种信息的传播及其反馈过程。广告用语是一种能产生市场效用的经济语言。体验营销具有即时性、差异性、互动性、主动性等特征,其根本原因在于消费者的体验需求。广告标语中的体验形式为感官、情感、思考、行动和关联,可以使产品在未被使用之前就增加其体验价值。 相似文献

传统无线局域网组网方式存在通信距离近、功耗高等问题,不能满足大型超市电子价签系统的通信要求。为此,提出一种基于LoRa(Long Range)通信技术的电子价签系统设计方案。采用具备LoRa调制方式的SX1278芯片作为系统LoRa模块的主芯片,以STM32单片机作为网关和节点价签的主控MCU,采用星型拓扑结构组网,并通过对通信过程中信噪比和接收信号强度两个参数值进行融合计算来分析信道状态,以此实现对数据传输速率的自适应调整。经实验测试,该系统通过服务器可经LoRa无线网络稳定传输数据,最终对电子价签显示内容进行更改,并有效提高了通信距离和降低功耗,可满足大型超市的实际需求。 相似文献

Despite the rise of digital, direct mailing as a marketing communication tool remains relevant and widely applied in practice. Nevertheless, research into the effectiveness of direct mailing in the online environment is scant. Key questions that remain entail how direct mails affect different online and offline consumer activity metrics throughout the purchase funnel and how they interact with digital marketing communication tools. The current paper, therefore, investigates these two questions by conducting two studies. First, we focus on the effect of direct mailing on zip-code level upper, middle, and lower funnel performance metrics over time by analyzing quasi-experimental data from a large European insurance firm. The results reveal that direct mailing significantly influences consumer activity metrics in the online channel (i.e., online search and clicking behavior), in support of cross-channel effects of direct mailing. Moreover, direct mailing is shown to be effective throughout the purchase funnel, both directly and indirectly, with a positive net sales effect. Second, we study the joint effect of direct mailing and display advertising by analyzing field experiment data from the same insurance firm. The results show positive synergy between direct mailing and display advertising. Therefore, despite the rise of digital, direct mailing still serves as an effective marketing tool, both by itself and in combination with digital marketing. 相似文献

本文认为,随着通讯技术的迅速发展,对于大规模分散系统管理的要求越来越高,因为这样的系统组成要素是不均匀或是异质性的,而且各个组成要素都会形成不同的信息,管理时会生成大量的项目输送量。为了有效地管理大规模分散系统,需要对发生项目进行过滤,并相机变换管理系统,增强其扩张性和减轻网络系统的负担。为此而进行的在分散系统基础上使用移动agent的研究,设计能够有效地移动agent的移动模式,协调以前移动agent的移动方法与应答提案方法之间的关系。 相似文献
