摘要： An electrical control system consisting of two or more electrical transmitting devices each capable of transmitting synchronized messages consisting of electrical pulses to devices connected to one or more of the three phases of the AC power lines in a typical three phase power system. The synchronized transmitters are each connected to neutral and to one or more of the three phases, A, B, and C, or across two of the phases, of different circuit breaker panels in a typical three phase power system, and are capable of transmitting messages to one or more of the three phases. The transmissions from the two or more transmitters are synchronized such that the transmitted pulses from each transmitter are transmitted at the same time to produce a message that can be received correctly at any receiving device connected to any of the connected circuit breaker panels.

摘要： The invention facilitates optical signals generated from customer premise equipment (CPE) at the edges of the metro domain networks. The CPEs are connected to extension terminals that transform the optical signal originating at the CPE into a suitable format for long haul transmission. The optical signal then propagates to a primary terminal where the signal is multiplexed with other optical signals from other extension terminals. The multiplexed signals are then transmitted over LH or ULH network to a second primary terminal where the signal is then demultiplexed from other optical signals and transmited to the proper extension terminal. At the extension terminal, the demultiplexed optical signal is transformed from its LH format back into a format suitable for interconnection to a CPE. Using this architecture, the signal under goes optical-to-electrical conversion only at the extension terminals or end points. These end points can be located in lessee's facility. The only equipment located in lessor's facility is the primary terminal containing line amplifiers and add/drop nodes.

摘要： Apparatus and methods for estimating the frequency of a sleep or slow clock using a fast clock, such as a temperature compensated crystal oscillator. The disclosed apparatus include an estimator having a first counter that receives sleep clock synchronized pulses issuing each cycle of the sleep clock period, yet are synchronized to a fast clock. The slow clock synchronized pulses are counted up to a predetermined number; whereupon a full count signal is issued. A second counter receives the full count signal and increments each time the full count signal is received. A third counter counts fast clock cycles until the full count signal occurs. Based on the number of counts of the slow and fast clock cycles, the frequency of the slow clock may be determined using only the domain of the fast clock for performing the measurement thereby tying accuracy of the measurement to the accuracy of the fast clock. The disclosed apparatus also include an integrated circuit and a transceiver employing the disclosed estimator. Corresponding methods are also disclosed.

摘要： A novel wavelength routing apparatus is disclosed, which uses a diffraction grating to separate a multi-wavelength optical signal from an input port into multiple spectral channels; a channel-interleaving assembly (e.g., an array of prisms) to interleave the spectral channels into two channel groups; and an “augmented relay system” to relay the interleaved channel groups onto two separate arrays of channel micromirrors, respectively. The channel micromirrors are individually controllable and pivotable to reflect the spectral channels into multiple output ports. As such, the inventive wavelength routing apparatus is capable of routing the spectral channels on a channel-by-channel basis and coupling any spectral channel into any one of the output ports. Further, the channel-interleaving scheme thus devised effectively “enlarges” the channel spacing and thereby allows the channel micromirrors in each array to be made considerably larger and more reliable, thereby significantly improving the channel filtering characteristics and ensuring more robust performance.
摘要翻译：公开了一种新颖的波长路由设备，其使用衍射光栅将多波长光信号与输入端口分离成多个光谱通道; 信道交织组件（例如，棱镜阵列）将频谱信道交织成两个信道组; 以及“增强中继系统”，分别将交织的信道组中继到两个独立的信道微镜阵列上。通道微镜可独立控制和可枢转，以将光谱通道反射到多个输出端口。因此，本发明的波长路由设备能够在逐个信道的基础上路由频谱信道，并将任何频谱信道耦合到任何一个输出端口。此外，由此设计的信道交织方案有效地“扩大”信道间隔，从而允许将每个阵列中的信道微镜做得相当大和更可靠，从而显着提高信道滤波特性并确保更强的性能。
