    • Mechanisms for interferer detection can detect interferers by detecting elevated signal amplitudes in one or more of a plurality of bins (or bands) in a frequency range between a maximum frequency (fMAX) and a minimum frequency (fMIN). To perform rapid interferer detection, the mechanisms downconvert an input signal x(t) with a local oscillator (LO) to a complex baseband signal xI(t)+jxQ(t). xI(t) and xQ(t) are then multiplied by m unique pseudorandom noise (PN) sequences (e.g., Gold sequences) gm(t) to produce m branch signals for I and m branch signals for Q. The branch signals are then low pass filtered, converted from analog to digital form, and pairwise combined by a pairwise complex combiner. Finally, a support recovery function is used to identify interferers.
    • 用于干扰源检测的机制可以通过在最大频率(fMAX)和最小频率(f M IN)之间的频率范围内检测多个箱体(或频带)中的一个或多个中的升高的信号幅度来检测干扰源。 为了执行快速干扰源检测,这些机制将本地振荡器(LO)的输入信号x(t)下变频为复基带信号xI(t)+ jxQ(t)。 然后将xI(t)和xQ(t)乘以m个唯一伪随机噪声(PN)序列(例如,Gold序列)gm(t),以产生用于Q的I和m个分支信号的m个分支信号。然后分支信号 低通滤波,从模数转换成数字形式,并由成对复合组合器成对组合。 最后,支持恢复功能用于识别干扰源。

    • An annuloplasty ring holder including a head having an upper surface and an annuloplasty ring receiving surface facing opposite the upper surface. The annuloplasty ring holder also includes means for attaching an annuloplasty ring to the annuloplasty ring receiving surface. The means for attaching an annuloplasty ring to the annuloplasty ring receiving surface may include one or more suture guides operatively associated with the head and configured to position one or more sutures to removably associate an annuloplasty ring with the annuloplasty ring receiving surface. The head may include a central hub and more than one spoke radiating out from the central hub. If the head is thus configured, each spoke will include a portion of the annuloplasty ring receiving surface.
