General Description :
IP1001 is an integrated physical layer device for 1000BASE-T, 100BASE-TX, and 10BASE-T applications. IP1001 supports MII, GMII and RGMII for different types of 10/100/1000Mb Media Access Controller (MAC). It supports Auto MDI/MDIX function to simplify the network installation and reduce the system maintenance cost. IP1001 supports speed down shift feature for a poor link quality to guarantee data transmission. Cable analysis function “SCA” is supported by programming MII registers of IP1001 through MDC/MDIO.

在對汽車未來技術的追求上,通用算得上積極的一個,從其對無人駕駛的布局可見一斑。而這種積極,也體現在了通用對其他汽車智能技術的研發中。
雷鋒網新智駕(AI-Drive)消息,日前,外媒從美國專利商標局獲悉,通用發布了一套全新的汽車空氣動力學系統專利,這款專利應用從2016年5月被申請,如今正式發布。
據雷鋒網了解,這款復雜的空氣動力學系統專利能夠通過傳感器和控制系統,自主調節汽車尾翼(擾流板)、汽車前定風翼、車底分流器,甚至是底盤高度,以達到最佳的動力性能。據猜測,通用旗下的高端超跑雪佛蘭克爾維特C7很可能成為最先應用該系統的車型。
雷鋒網在官方發布的專利文件中發現,該專利應用被描述為一款“汽車空氣動力性能控制系統”,功能包括根據環境傳感參數調節汽車的底盤高度,以達到最佳的空氣動力性能。
下圖展示了克爾維特車型基于專利系統的改裝簡圖,從圖中能夠看出,系統對于汽車的車底分流器、前定風翼、氣壩、發動機罩散熱柵等部件均有所改裝,此外,系統在底盤升降的自主調節上取得了一定進展,其中包括超聲波雷達、毫米波雷達等傳感器單元測量,以及控制系統的配合等。
