摘要： A pre-averager for digitally averaging the samples of an input data signal (26) over two or more symbols, the averaging interval being defined by the input sampling rate divided by the output sampling rate. As the averaged sample is clocked (29o, 29e) to a suitable detector at a much slower rate than the input signal sampling rate the noise bandwith at the input to the detector is reduced. The pre-averager forms a data filter (50a, 50b, 50c, 50d) having an output sampling rate of one sample per symbol of received data. More specifically, selected ones of a plurality of samples accumulated (28a, 28b, 28c, 28d) over two or more symbol intervals are output in response to clock signals at a rate of one sample per symbol interval. The pre-averager includes circuitry (40, 44) for weighting digitized signal using stored finite impulse response (FIR) filter coefficients (42).
摘要翻译：预平均器，用于在两个或更多符号上对输入数据信号（26）的样本进行数字平均，平均间隔由输入采样率除以输出采样率确定。由于平均样本以比输入信号采样速率慢得多的速率被定时（29o，29e）到合适的检测器，因此检测器输入处的噪声带宽减少。预平均器形成数据滤波器（50a，50b，50c，50d），其具有每接收数据码元一个采样的输出采样率。更具体地说，响应于每符号间隔一个样本的速率的时钟信号，输出在两个或更多个符号间隔上累积的多个样本（28a，28b，28c，28d）中的选定样本。预平均器包括用于使用存储的有限脉冲响应（FIR）滤波器系数（42）对数字化信号进行加权的电路（40,44）。

摘要： A common pressure vessel type Ni-H₂ battery having a thermally conductive rack (3) disposed within the pressure vessel (5) and having an outer wall conforming to and in thermal contact with the inner surface of a cylindrical centre wall portion (16) of the pressure vessel and a plurality of fins (21) dividing the rack into a plurality of compartments. A Ni-H₂ battery cell is disposed in each of the compartments in thermal contact with adjacent ones of the fins. A plurality of flexure springs (51) extend between the racks (3), providing a radial force on the racks so as to urge the outer walls of the racks into contact with respective portions of the wall of the pressure vessel. A stopper (73) is formed internally of the pressure vessel and a wave spring (72) is disposed between a weld ring (70) provided at the end of the rack opposite the stopper for forcing the racks in the longitudinal direction of the pressure vessel into contact with the stopper.

摘要： In a secure communications system, a key number which is changed periodically, e.g. monthly, and a random number from a random number generator are combined and used as a seed to reset a PN sequence generator, with the output of the generator being used to control encryption of transmission data in a signal processor. The key is also provided to a first encipherer to encipher the random number for transmission with the encrypted data. At the receiver, the key is provided on common to a decipherer for deciphering the random number and a PN sequence generator which is periodically reset by the combination of the key and random number in the same manner as in the transmitter. The PN sequence is then used to decrypt the information. User identification codes are stored in the transmitter and are used to encipher the key, with each employing its ID code to decipher the key. The user ID codes are known only to the system operator, so that not even a particular user can know the key.

摘要： A method for rejuvenating Ni-H₂ battery cells suffering a voltage anomaly providing an improved cell output voltage and capacity. After the battery containing the cells suffering the voltage anomaly is removed from service, the battery is discharged. Discharging the battery reduces the hydrogen pressure within the cells, thereby increasing the rate of mass transport of free water back to the electrode stack of the cells. The cells are then left to stand for a period sufficient to allow any free water to diffuse back to the electrode stacks.

摘要： A printed-circuit antenna array having broadband linear polarization, and circular polarization with high polarization purity, feedlines (2) of the array being capacitively coupled to feeding elements (3) at a single feedpoint or at multiple feedpoints, the feeding elements in turn being electromagnetically coupled to corresponding radiating elements (4). The radiating elements may be patches, disposed on a dielectric board which is contactlessly coupled to another board containing the feeding elements. Alternatively, the radiating elements may be slots, formed by an absence of material in ground planes which are formed on the same dielectric board as the feeding elements. Still further, both radiating patches and radiating slots may be used. The exclusively contactless coupling enables simple, inexpensive multilayer manufacture.
