摘要： An intervote modulator (10) includes a majority voting logic unit (12) and an interplex modulator (14). The majority voting logic unit receives plural signal codes (e.g., five codes x1, x2, x3, x4, x5) together with their respective target gains G1, G2, G3, G4, G5 representing the desired transmit power for the individual signal codes. The majority voting logic unit combines three of these five signal codes to form a majority vote composite signal while keeping the other two signal codes uncombined. The majority vote composite signal and the two uncombined signals are then supplied to the interplex modulator as signals s1, s2 and s3. The interplex modulator applies interplex modulation to signals s1, s2 and s3 to form the in-phase and quadrature components of the final composite signal. The majority voting logic unit employs a generalized majority vote involving an interlace of sub-majority votes determined on a chip-by-chip basis.

摘要： CDMA codes are multiplexed into a constant-envelope composite signal using weighted majority logic. Based on a commanded power allocation among the signal codes, each signal code is assigned a weighting coefficient dictating the voting power the signal code has each time a vote is conducted, in a manner analogous to corporate shareholder voting. To multiplex the signal codes, a majority vote is conducted each chip period by summing the weighted chip values of the signal codes and assigning a binary value to the majority-voted composite chip based on the sign of the sum. An RF carrier is modulated in accordance with the value of the composite chip. The desired power distribution is achieved by requiring the power ratio of each signal code to be proportional to the square of the expected value of the cross-correlation between the signal code and a stored replica of the signal code at the receiver.

摘要： There is disclosed a method for rapid refueling of a nuclear reactor. The upper package including the head and upper internals and control rods of the reactor includes a missile shield and by engagement with the shield is moved to a refueling position in a single lifting operation exposing the core in the lower package. The fuel assemblies are then replaced. The removal of the control rods from the core with the upper package is compensated for by an increase in the concentration of neutron absorber, such as boron including B.sup.10, in the medium in which the core is immersed. Typically, the refueling can take place in a few days, at intervals of two to six months. During refueling a fraction of the assemblies are replaced. Because of the facility for rapid refueling and consequent lower time cycle for refueling, the fuel can be of low enrichment and the concentration of neutron absorber in the reactor coolant medium can be decreased. All replacement assemblies can be moved in a cart into the reactor containment in a single operation and replaced from the cart, or the assemblies can be moved one-by-one into the containment and replaced as they are presently.
摘要翻译：公开了一种用于快速加油核反应堆的方法。包括反应器的头部和上部内部件和控制棒的上部包装包括导弹屏蔽，并且通过与屏蔽件的接合在单个提升操作中移动到加油位置，从而暴露下部封装件中的芯部。然后更换燃料组件。通过在芯体浸渍的介质中中子吸收体（包括B10的硼）的浓度的增加来补偿具有上部封装的芯体的控制棒的去除。通常，加油可以在几天内进行，间隔两到六个月。在加油期间，一部分组件被更换。由于用于快速加油的设备和随之而来的用于加油的较低时间循环，燃料可以具有低富集性，并且能够降低反应堆冷却剂介质中的中子吸收剂的浓度。所有更换组件可以在一个单独的操作中在一个推车中移动到反应堆容器中，并从推车中更换，或者组件可以一个一个地移动到密封件中并按照目前的方式进行更换。

摘要： Systems and methods are described here for locating the position of a mobile terminal in a cellular communications system. A base station in the cellular communication system broadcasts a communication signal having embedded therein a navigation signal. The navigation signal uses a chirp technique in which the chirp signal includes two portions, an up-chirp portion and a down-chirp portion. Each portion of the chirp signal is synchronized with a frame in the communication signal. The chirp navigation signal is at a power level much lower than the communication signal so as not to interfere with the communication signal. A mobile terminal generates a corresponding chirp signal to correlate with the incoming signal and to extract the navigation signal. The mobile terminal uses the detected navigation signal to determine a time of arrival of the communication signal for use in determining the position of the mobile terminal either at the terminal or to send to a network center for location processing.

摘要： A multiplexer and a method for chip-synchronous code-division multiple access (CDMA) signals produces a constant envelope signal. The output signal of the multiplexer permits use of a saturating (Class C) high power amplifier (HPA) resulting in a net increase in effective transmitter power usage. This multiplexer applies to a variety of CDMA spread spectrum modulation formats and has many applications, such as the IS-95 forward link interface, and CDMA and CDMA/FDMA (frequency-division multiple access) applications, including general cellular base station forward traffic channels, cellular subscriber station multiple-channel reverse traffic channels (e.g. IS-95 subscriber Internet access) and satellite downlinks.

摘要： A water storage tank in the coolant water loop of a nuclear reactor contains a tubular heat exchanger. The heat exchanger has tubesheets mounted to the tank connections so that the tubesheets and tubes may be readily inspected and repaired. Preferably, the tubes extend from the tubesheets on a square pitch and then on a rectangular pitch therebetween. Also, the heat exchanger is supported by a frame so that the tank wall is not required to support all of its weight.
