    • A properly modulated carrier signal exits transmission circuitry (201) and enters a first and a second mixer (203, 205). The modulated carrier is mixed with a first and a second function by the first and the second mixers (203, 205). The functions are generated by a first and a second signal generator (207, 209). The mixed signals exit the mixers (203, 205), and are amplified (via amplifiers 211-213), to be radiated by an antenna (211). The antenna (221) comprises two orthogonal antenna elements (215, 217), that are in close proximity with one another (although not in contact). One of the mixed signals is radiated on a first element (215), and the other mixed signal is radiated on the second element (217). The resulting signal transmitted from the antenna (221) is the original carrier signal having the plane of polarization constantly changing. Thus a reflected signal emitted an instance earlier cannot interfere with a wave currently emitted.
    • 一个适当调制的载波信号离开传输电路(201)并进入第一和第二混频器(203,205)。 调制载波与第一和第二混频器(203,205)的第一和第二功能混合。 功能由第一和第二信号发生器(207,209)产生。 混合信号离开混频器(203,205),并被放大(通过放大器211-213),由天线211辐射。 天线(221)包括彼此非常接近(尽管不接触)的两个正交天线元件(215,217)。 混合信号中的一个被辐射在第一元件(215)上,而另一个混合信号被辐射在第二元件(217)上。 从天线(221)发送的结果信号是具有偏振平面不断变化的原始载波信号。 因此,较早发射的反射信号不能干扰当前发射的波。

    • A heat exchange apparatus including a housing, a first array of fluid conduits provided within the housing, and a second array of fluid conduits provided within the housing. The first and second arrays of fluid conduits are configured to carry a first fluid. The heat exchange apparatus also includes a first fluid passageway provided within the housing, where the first fluid passageway is defined by an internal surface of the housing and by a baffle plate. The first fluid passageway is configured to carry a second fluid. The baffle plate is configured to divide the first fluid passageway into a first flow path and a second flow path, where the first array of fluid conduits extends through the first flow path and the second array of fluid conduits extends through the second flow path.
