    • An external combustion thermodynamic system includes a compression stage for substantially adiabatically compressing a working medium to raise the temperature of the medium and an expansion stage for substantially adiabatically expanding the medium to decrease the temperature of the medium. A first heat exchanger is coupled to the compression stage and the expansion stage to allow the expanded medium to pass therebetween and is structured to transfer heat substantially isochoricly (i.e., at constant volume) between the cold reservoir and the expanded medium. A second heat exchanger is coupled to the compression stage and the expansion stage to allow the compressed medium to pass therebetween. The second heat exchanger is structured to transfer heat substantially isochoricly between the compressed medium and the hot reservoir. The thermodynamic system also includes a recuperative heat exchange loop for transferring heat between the expanded medium within the first heat exchanger and the compressed medium within the second heat exchanger. The thermodynamic system approaches the thermal efficiency of a Stirling engine without the need for a regenerator.

    • The aim of the invention is to limit the number of possible phase ambiguity resolutions when taking measurements by means of satellite-aided positioning systems. Said aim is achieved by a method which allows the search sector to be better restricted. To this avail, information about the geometry of an antenna array is used for establishing restrictions for said antenna array. Said restrictions allow the search sector and thus the number of acceptable resolutions to be successively reduced. A restriction comprises the utilization of the connecting line between two antennas (A0, A1) that define a primary base line (S01). An additional, secondary base line (S0x) can be calculated by inventively parameterizing the degree of rotational freedom of said secondary base line (S0x) about the primary base line (S01) such that the process is accelerated.
    • 本发明的目的是通过卫星辅助定位系统来进行测量时限制可能的相位模糊度分辨率的数量。 所述目的通过允许更好地限制搜索扇区的方法来实现。 为此,使用关于天线阵列的几何形状的信息来建立对所述天线阵列的限制。 所述限制允许搜索扇区和因此可接受的分辨率的数量被连续地减少。 限制包括利用限定主基线(S 01)的两个天线(A 0,A 1)之间的连接线路。 可以通过以下方式来计算附加的次级基线(S 0 x):通过发明地参数化关于主基线(S 01)的所述次基准线(S 0 x)的旋转自由度来加速该过程。
