    摘要: Systems and methods for aligning the phase of a PLL with an incoming data signal. In one embodiment, when a data signal is received in a PLL, a phase perturbation signal is generated and injected into the PLL. The PLL then performs a phase alignment procedure to lock on to the received data signal. The phase perturbation signal is a damped sinusoidal oscillation that is injected into the PLL when each of a plurality of data packets is received. The perturbation signal has an amplitude sufficient to bump the PLL out of a quasi-stable state around 180 degrees out of phase with the incoming data signal, but is damped to less than a degree of phase shift within 30 ns of being injected.

    摘要: Systems and methods for determining a slicing level which is used as a threshold to determine whether timeslots of an incoming data signal contain ones or zeros. The method of one embodiment comprises receiving a data signal, identifying a maximum level of the data signal, identifying a minimum level of the data signal, determining an average of the minimum and maximum levels, and then using the average of the minimum and maximum levels as a slicing level to identify bits of a data packet embodied in the data signal.

    摘要: Embodiments of the present invention provide a system and method for routing optical data. In one embodiment of the present invention, data can routed in a non-blocking fashion from a plurality of the ingress edge units to a plurality of egress edge units by selectively connecting the ingress edge units to the egress edge units at a photonic core. Switching at the photonic core can be driven by a clock signal and does not require an electrical to optical conversion to occur at the core. This can allow switching on the nanosecond level, substantially faster than many prior art systems.

    摘要: A loading mechanism includes a fastening board, a cam, a rotary pivot, and a load module. The fastening board defines a pivot hole at the center portion of the fastening board and a sliding guide adjacent to the pivot hole. The cam defines a locating hole and an annular guide. The load module includes two guiding poles, a follower fastened to one end of the two guiding poles, and a clamping member fastened to the other end of the two guiding poles. The distance between a part of the annular guide and the locating hole is gradually decreased, and the cam can be driven to rotate. The cam drives the follower to slide along the annular guide to drive the load module to slide along the sliding guide.

    摘要: A method for generating diffuse reflection light and a diffuse reflection lamp are provided. The diffuse reflection lamp comprises a reflective plate (10), a connector (20) and a dragging device (40). The reflective plate (10) is removably fixed on the lamp by the connector (20) to reflect the light from the lamp. One end of the dragging device (40) is connected with the reflective plate (10), and the other end is connected with the connector (20); or the dragging device (40) hoops around the outer edge of the reflective plate (10). Therefore, the reflective plate (10) is elastically bended toward and formed into a curved arc surface to collect the diffuse reflection light.
