    • A method of estimating the occurrence of a specific tire pressure deviation between actual and nominal pressure values for one or a plurality of wheels (i) is provided. One or more wheel radius analysis measurement values (ΔR) are subsequently obtained from a wheel radius analysis component (104), wherein the wheel radius analysis measurement values (ΔR) are related to single wheel radius values (Δri) of which each is indicative of the wheel radius of a particular wheel (i). One or more wheel vibration data values (Δƒi) are subsequently obtained from a wheel vibration analysis component (102), wherein each of the wheel vibration data values (Δƒi) is indicative of a vibration phenomena in the time dependent behavior of the rotational velocity of a particular wheel (i). One or more tire pressure output values (ηi, Δpi) are calculated on the basis of both the wheel radius analysis measurement values (ΔR) and the wheel vibration data values (Δƒi) wherein each tire pressure output value (ηi, Δpi) is indicative of the specific tire pressure deviation for a particular wheel (i).
    • 提供了一种估计一个或多个轮(i)的实际和标称压力值之间的特定轮胎压力偏差的发生的方法。 随后从车轮半径分析部件(104)获得一个或多个车轮半径分析测量值(DeltaR),其中车轮半径分析测量值(ΔR)与单轮半径值(Deltar< >),其各自表示特定车轮(i)的车轮半径。 随后从车轮振动分析部件(102)获得一个或多个车轮振动数据值(Deltaf< i>),其中车轮振动数据值(Deltaf< 表示特定车轮(i)的旋转速度的时间相关行为中的振动现象。 基于车轮半径分析测量值(DeltaR)和车轮振动数据值两者来计算一个或多个轮胎压力输出值(eta,Deltap) (Deltaf)其中每个轮胎压力输出值(eta,DeltapΠi)表示特定车轮的特定轮胎压力偏差 (一世)。

    • A reconfigurable multi-output antenna (16) is disclosed comprising: one or more radiating elements (12, 14), at least two matching circuits (42, 44, 50, 52) coupled to the or each radiating element (12, 14) via e.g. a splitter (30, 32) or a duplexer; and wherein each matching circuit (42, 44, 50, 52) is associated with a separate port (38, 40, 46, 48) arranged to drive a separate resonant frequency so that the or each radiating element (12, 14) is operable to provide multiple outputs simultaneously. The resonant frequency of each output is independently controllable by each matching circuit, with good isolation with each other port, thereby offering very wide operating frequency range with simultaneous multi-independent output operations. Also described is a multi-output antenna control module for coupling to one or more radiating elements, an antenna structure and an antenna interface module. A reconfigurable multi-output antenna is disclosed comprising: one or more radiating.
