    • A method and apparatus for assembling a multi-panel door. The method includes the steps of fashioning a plurality of rails; fashioning a plurality of panels; fashioning a plurality of mullions; fashioning a plurality of stiles; and preassembling selected rails, selected panels, and selected mullions into sub-assemblies of the door. The sub-assemblies are positioned intermediate a first stile and a second stile in a pre-assembly orientation with the first stile and second stile generally coplanar with the sub-assemblies. The sub-assemblies, the first stile, and the second stile are compressively urged together in two substantially perpendicular axes to create a squared assembly with respect to the two axes. The sub-assemblies are intermediate the first stile and the second stile and are affixed to the first stile along at least a portion of the first stile, and are affixed to the second stile along at least a portion of the second stile.

    • A frequency agile phase detector includes a digital frequency detector section connected to a hold-sample-hold phase detector section. The digital frequency detector develops control signals related to frequency differences between a reference periodic signal and a variable periodic signal. The control signal determines the amplitude of a voltage signal impressed across a first hold circuit. A sample signal acts to sample and transfer the sample voltage signal from the first to a second hold circuit so as to reduce phase differences between the reference and variable periodic signals. The detector is incorporated into a phase locked loop using the VCO output as the variable periodic signal so that acquisition and lockup of the loop is obtained even when the two periodic signals are decades apart. Additionally, the hold-sample-hold section aids in reducing the reference and sampling energy required which results in a spectrally pure output signal.
    • 频率敏捷相位检测器包括连接到保持采样保持相位检测器部分的数字频率检测器部分。 数字频率检测器产生与参考周期信号和可变周期信号之间的频率差有关的控制信号。 控制信号确定在第一保持电路上施加的电压信号的幅度。 采样信号用于采样并将采样电压信号从第一保持电路传送到第二保持电路,以减小参考和可变周期信号之间的相位差。 使用VCO输出作为可变周期信号将检测器并入到锁相环中,使得即使当两个周期信号几十分钟时也获得和锁定环路。 此外,保持采样保持部分有助于减少所需的参考和采样能量,从而产生光谱纯的输出信号。

    • A closure, such as a door or window unit, and a joint for such a closure are provided. The closure has an inside and an outside, and includes a plurality of first frame members alternately joined to a plurality of second frame members to form a planar frame, and a panel member is positioned within the frame. The joint, formed at each location where a first frame member abuts a second frame member, includes an end area of a first frame member, a mating area of a second frame member and a sealing member. The sealing member is disposed at the interface defined between the end area and the mating area to establish a weather-resistant barrier between the inside and the outside of the closure. A method for fabricating a closure is also provided.

    • A frequency agile homodyne full duplex FSK system having a receiver section using an image-cancellation mixer wherein sum and difference signals generated by a pair of double-balanced mixers are added together with proper phase to cancel out the image response normally associated with heterodyne receivers and directly down-convert the carrier frequency to the baseband frequency. The transmitter section of the FSK system consists of an FSK modulator whose peak deviation is controlled by an active derivative of a crystal clock. The FSK modulator functions in the manner of a phasing single sideband (SSB) mixer with upper or lower sideband signals generated by the proper phasing of quadrature components of the carrier frequency and the peak deviation signal derived from a crystal clock.
