摘要： A power supply generates alternating current and direct current from a constant-voltage source. A multi-phase pulse width modulation voltage source inverter is connected across the source to output multi-phase alternating current. At least one waveform generator is bridged in parallel with the inverter, with each waveform generator outputting zero-sequence waveform current compensated to maintain the multi-phase current within a predetermined tolerance from a desired set point. A rectifier receives the waveform current and generates direct current.

摘要： A machine powertrain includes an engine operably connected to a torque converter and a transmission. A switch associated with the torque converter provides a locking signal indicative of a locked or unlocked condition of the torque converter. A throttle sensor associated with the throttle provides a throttle signal. An electronic controller receives the locking signal and the throttle signal, and controls operation of the engine at least partially based on the throttle signal and the locking signal. The electronic controller determines whether a locked or unlocked condition of the torque converter is present based on the locking signal, determines whether a part throttle operating condition or a full throttle operating condition is present based on the throttle signal, and selects a load-control power curve when the part throttle operating condition is present and when the torque converter switches from the unlocked to the locked condition.

摘要： A protective barrier laminate underlayment used to cover the surface of a structure, such as a house, just beneath the outermost, weather bearing layer. The underlayment has an adhesive layer on its lower side for securing the underlayment to the roof and a pattern of adhesive areas on its upper side for allowing a construction worker to walk on the underlayment without slipping. The upper adhesive layer also prevents tools and other objects such as stacks of shingles from sliding off of the roof during construction.

摘要： A method and system for improving sensitivity of microwave and millimeter phase discriminators is disclosed. An exemplary embodiment of a phase discriminator includes two mixers inserted between two 90 degree hybrids. One hybrid splits the reference or LO signal into two signals of equal magnitude with a phase difference of 90 degrees. Similarly, the other hybrid splits the received RF signal into equal signals shifted 90 degrees in phase. One mixer receives an input set (e.g., LO and RF signals) with a zero-degree phase shift, and the other mixer receives the input set shifted in phase by 90 degrees. Thus, the leakage signals at the output of each mixer have the same magnitude but are 180 degrees apart in phase. The IF ports of the mixers are tied together, allowing the leakage signals of the mixers to combine destructively, thereby increasing isolation and sensitivity.

摘要翻译： 公开了一种提高微波和毫米相鉴别器灵敏度的方法和系统。 鉴相器的示例性实施例包括插入两个90度混合器之间的两个混频器。 一个混合器将参考或LO信号分成两个相等幅度的信号，相位差为90度。 类似地，另一个混合器将接收的RF信号分为相位移90度的相等信号。 一个混频器接收具有零度相移的输入组（例如，LO和RF信号），而另一个混频器接收相位偏移90度的输入组。 因此，每个混频器的输出处的泄漏信号具有相同的幅度，但相位相差180度。 混频器的IF端口连接在一起，允许混频器的泄漏信号破坏性结合，从而增加隔离度和灵敏度。
