Note 1:
“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of “Electrical Characteristics” specify conditions for device operation.
Note 2:
Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground unless otherwise
specified.

语音作为自然的人机接口，可以使车载导航系统实现更安全、更人性化的操作。通过国内外车载导航系统的功能对比可知，支持语音交互是车载导航系统的一个发展趋势。另外，市场信息服务公司J.D Power and Associates的调研数据也表明，56％的消费者更倾向于选择声控的导航系统。因此，开发车载语音导航系统是很有意义的。目前，国内已经具备开发车载语音导航系统的技术基础，特别是文语转换TTS技术...[详细]
“tensymetry”这个词在《韦伯斯特词典》中没有解释，但在医学界却广为人知。由Tensys Medical Systems公司开发的tensymetry是一种使用生物机械、电气、软件工程的专有组合技术。利用这三种强大的技术，你可在手术室内对病人的心跳血压进行精确、连续、实时和非侵入性测量。 该技术结出的果实就是该公司的T-line Tensymeter产品。该产品线的最新进展是去年...[详细]
