摘要： A method and system is disclosed for locking and releasing a module utilized in a transceiver system that includes a plurality of modules in close proximity with one another. The module is generally configured to include a handle with an associated cam formed in a first section of the module. The handle is moveable in a direction to allow the cam to move an associated ejector button integrated with the module in order to release the module from the transceiver system, thereby permitting the module to be efficiently removed from the transceiver system. The module may thus be removed from the transceiver system utilizing the handle. The module may be locked into the transceiver system when the handle is placed in an upward position.

摘要： A shoelace knot retaining apparatus comprises an upper tab member, a lower tongue member and a fold for enabling the upper tab member and the lower tongue member to fold away from each other to dispose only one of the upper tab member and the lower tongue member to engage the shoelace knot. Further, the fold enables both of the upper tab member and the lower tongue member to engage the shoelace knot, whereby the upper tab member and the lower tongue member are disposed in a shoelace knot securing position to prevent the shoelace knot from untying. In particular, one of the upper tab member and the lower tongue member has at least one first opening of a diameter substantially equal to the diameter of the shoelace to thereby limit the movement of the shoelace with respect to the one opening. The other of the upper tab member and the lower tongue member has at least one second opening. Each of the one first opening and the one second opening has respectively a first extremity and a second extremity. The first extremity and the second extremity are being disposed with respect to each other so that when the upper tab member and the lower tongue member are disposed in the shoelace securing position, the first extremity intersects the second extremity and the one member blocks at least a part of the second opening whereby the first and second extremities grip the show lace therebetween to prevent the shoelace from being withdrawn from the shoelace retaining member.

摘要： A wireless digital transmission and receiving method combines phase reversal keying with pulse position modulation. Modulation of a transmitted signal implements pulses that are of extremely short duration to indicate ones and zeros. These pulses can be as narrow as one cycle of the carrier frequency. As such, they often appear as missing cycles or pulses in a sequence of carrier cycles. The method synthesizes a sideband with no carrier or other sidebands from the carrier of an input signal. This synthesized sideband is represented by a broad sinx/x spectrum with a principal power peak at the modulated frequency and numerous weaker peaks of varying frequencies and peak levels. The time duration of these smaller peaks is such that they have negligible mean power levels. Thus, the synthesized signal can withstand the degradation caused by multipath interference and fading. The weaker peaks also do not cause measurable interference with other communications devices. The smaller peaks can have amplitudes far below the noise level of the system. Hence, the smaller peaks are not a necessary or an important component of the signal. The result is a strong signal in the form of a synthesized single sideband with all the useful modulation in the brief phase reversal period with a constant signal in the remainder of the bit period that can be used to establish a reference to create uniform time rise and amplitude.
摘要翻译：无线数字发送和接收方法将相位反转键控与脉冲位置调制相结合。传输信号的调制实现了持续时间非常短的脉冲，表示1和0。这些脉冲可以与载波频率的一个周期一样窄。因此，它们通常在载波周期的序列中表现为丢失的周期或脉冲。该方法从输入信号的载波合成没有载波或其它边带的边带。该合成边带由广泛的sinx / x光谱表示，其中调制频率处的主要功率峰值和变化频率和峰值电平的许多较弱的峰值。这些较小峰值的持续时间使得它们具有可忽略的平均功率水平。因此，合成信号可以承受由多径干扰和衰落引起的劣化。较弱的峰值也不会对其他通信设备造成可测量的干扰。较小的峰值的幅度可能远低于系统的噪声水平。因此，较小的峰值不是信号的必需或重要组成部分。结果是在合成的单边带形式的强信号，其在短暂相位反转周期中具有所有有用的调制，在位周期的剩余部分中具有恒定的信号，可以用于建立参考以产生均匀的时间上升和振幅。

摘要： A method and apparatus for transmitting information combining abrupt phase change modulation with an ultra narrow band filter to remove unnecessary Fourier sidebands, resulting in a single frequency being transmitted to carry data. The method examines and detects the changes in the carrier phase only, after filtering to remove or reduce all sidebands, to obtain a usable signal. Only a single frequency with phase changes is transmitted. An ultra narrow band filter, having a rapid rise time and near zero group delay, passes the near instantaneous modulation changes of phase in the carrier.
