Question

【題目】Swiss researchers said Monday they have developed a wireless camera system to monitor vital signs in premature babies, a move that could replace uncomfortable and highly inaccurate skin sensors (傳感器) which produce false alarms in up to 90 percent of cases, mainly set off by the baby’s movement.

“This is a cause of discomfort for the babies, because we have to check on them every time,” said Jean-Claude Fauchere, a doctor at University Hospital Zurich’s newborn clinic.

His hospital is preparing to begin tests of a new, contactless system created by researchers at the EPFL polytechnical university in Lausanne and at the Swiss Center for Electronics and Microtechnology.

The system designed in Switzerland should allow premature babies kept warm in incubators (恒溫箱) to be medically monitored using highly sensitive cameras that detect the newborn’s pulse by analyzing its skin color, which changes so slightly every time its heart beats.

“Breathing is monitored by measuring movements of its chest and shoulders. At night, infrared (紅外線的) cameras take over, and monitoring can be carried out non-stop,” the statement said.

The visual system was designed by CSEM researchers, who chose cameras sensitive enough to detect minute changes in skin color, while the EPFL researchers designed algorithms (運(yùn)算程序) to process the data in real time.

“We ran an early study on adults, where we looked at a specific part of skin on their foreheads,” EPFL doctoral student Sibylle Fallet said. “With our algorithms we can track this area when the person moves, and use tiny changes in their color to determine the pulse,” she said. “The tests showed that the cameras produced practically the same results as conventional sensors.”

Once the system has been widely tested on premature babies, it could one day replace skin sensors altogether, the schools said.

【解析】

本文是一篇說(shuō)明文，介紹了一種新型用來(lái)監(jiān)測(cè)早產(chǎn)兒的無(wú)線相機(jī)監(jiān)測(cè)系統(tǒng)，這種新系統(tǒng)比傳統(tǒng)的傳感器更加準(zhǔn)確和舒適。

【1】推理判斷題。根據(jù)第一段a move that could replace uncomfortable and highly inaccurate skin sensors (傳感器) which produce false alarms in up to 90 percent of cases, mainly set off by the baby’s movement.可知這種新型無(wú)線相機(jī)系統(tǒng)可以取代以前的令人不舒服也不準(zhǔn)確的傳感器，也就是說(shuō)這種新的系統(tǒng)令人舒服也很準(zhǔn)確。故D項(xiàng)正確。

【2】推理判斷題。根據(jù)第四段using highly sensitive cameras that detect the newborn’s pulse by analyzing its skin color, which changes so slightly every time its heart beats.可知這種新型系統(tǒng)可以使用高度敏感的相機(jī)，這種相機(jī)可以監(jiān)測(cè)早產(chǎn)兒的皮膚顏色變化。這一特點(diǎn)是這個(gè)系統(tǒng)的關(guān)鍵所在。故C項(xiàng)正確。

【3】推理判斷題。根據(jù)倒數(shù)第二段最后一句“The tests showed that the cameras produced practically the same results as conventional sensors.”可知早期研究結(jié)果說(shuō)明新系統(tǒng)測(cè)量的數(shù)據(jù)和傳統(tǒng)的感應(yīng)器效果是一樣的。說(shuō)明這項(xiàng)早期研究是很成功的。故A項(xiàng)正確。

【4】推理判斷題。根據(jù)文章倒數(shù)第二段可知對(duì)這種系統(tǒng)的早期研究很成功，而且這種系統(tǒng)比傳統(tǒng)系統(tǒng)更加準(zhǔn)確更加舒適，未來(lái)可能取代現(xiàn)在的的感應(yīng)器�？芍�作者對(duì)這一系統(tǒng)的態(tài)度是樂(lè)觀的。故B項(xiàng)正確。
