Avalanche photo diode (APD) receiver modules arewidely used in fi ber optic communication systems. AnAPD module contains the APD and a signal conditioningamplifi er, but is not completely self contained. It stillrequires signifi cant support circuitry including a highvoltage, low noise power supply and a precision currentmonitor to indicate the signal Strength. The challenge issqueezing this support circuitry into applications withlimited board space. The LT®3482 addresses this challengeby integrating a monolithic DC/DC step-up converter andan accurate current monitor. The LT3482 can supportup to a 90V APD bias voltage, and the current monitorprovides better than 10% accuracy over four decades ofdynamic range (250nA to 2.5mA).

提出了一種基于PIC16F877A微控制器和CC2500射頻收發器芯片的低功耗、低成本RFID(Radio Frequency Identification, 無線射頻識別)局域定位系統設計方法,介紹了系統的定位工作原理、主要硬件電路模塊及定位算法的設計和實現。采用基于序列號對時隙數運算的排序算法有效解決了多標簽識別碰撞的問題,基于射頻輻射強度(Received Signal Strength Indication, RSSI)和圓周定位算法實現了基于RFID多標簽系統的平面定位。實驗測試表明,這種射頻定位方法能夠實現一定精度下的無線局域定位的功能。

為解決現Z-Stack定位程序代碼量大,結構復雜等問題,提出一種基于TinyOS的CC2430定位方案。在分析TinyOS組件架構基礎上,設計實現盲節點、錨節點與匯聚節點間的無線通信以及匯聚節點與PC機的串口通信。在此基礎上實現PC對各錨節點RSSI(Received Signal Strength Indicator)寄存器值的正確讀取,確定實驗室環境下對數-常態無線傳播模型的具體參數,并采用質心算法來提高定位精度。實驗顯示,在由四個錨節點組成的4.8×3.6 m2矩形定位區域中,通過RSSI質心定位算法求得的盲節點坐標為(2.483 1,1.018 5),實際坐標為(2.40,1.20),誤差為0.199 6 m,表明較好地實現對盲節點的定位。

改變文字顏色和背景色可以得到不同的效果。文字顏色修改,只要修改filter:glow(color=red,Strength=2) 中的color項,Strength為顏色的深度值 。

American Gladiator,You are consulting for a game show in which n contestants are pitted against n gladiators in order to see which contestants are the best. The game show aims to rank the contestants in order of Strength this is done via a series of 1-on-1 matches between contestants and gladiators. If the contestant is stronger than the gladiator, then the contestant wins the match otherwise, the gladiator wins the match. If the contestant and gladiator have equal Strength, then they are “perfect equals” and a tie is declared. We assume that each contestant is the perfect equal of exactly one gladiator, and each gladiator is the perfect equal of exactly one contestant. However, as the gladiators sometimes change from one show to another, we do not know the ordering of Strength among the gladiators.

This standard describes a keyed-hash message authentication code (HMAC), a mechanism for message authentication using cryptographic hash functions. HMAC can be used with any iterative Approved cryptographic hash function, in combination with a shared secret key. The cryptographic Strength of HMAC depends on the properties of the underlying hash function. The HMAC specification in this standard is a generalization of Internet RFC 2104, HMAC, Keyed-Hashing for Message Authentication, and ANSI X9.71, Keyed Hash Message Authentication Code.
