    • An optical fiber emulator. The emulator receives a digitally-encoded optical signal; demodulates the optical signal to produce serial electrical pulses representative of the digital signal; converts the serial pulses to parallel pulses; propagates the parallel pulses through a shift register whose propagation time is less than or equal to the time of a length of fiber to be emulated. The emulator then converts the parallel pulses at the output of the shift register to serial pulses; modulates an optical carrier with the serial pulses from the shift register; and attenuates the modulated optical signal an amount corresponding to the length of the fiber being emulated to produce an output optical signal whose propagation time is substantially equal to that of a section of optical fiber to be emulated. The shift register may be tapped at any point to obtain an output delayed by a desired amount corresponding to a selected section of optical fiber.
    • 光纤仿真器。 仿真器接收数字编码的光信号; 解调光信号以产生表示数字信号的串行电脉冲; 将串行脉冲转换为并行脉冲; 通过移位寄存器传播并行脉冲,该移位寄存器的传播时间小于或等于要仿真的光纤长度的时间。 然后,仿真器将移位寄存器输出端的并行脉冲转换为串行脉冲; 用移位寄存器的串行脉冲调制光载波; 并且将经调制的光信号衰减到对应于被仿真的光纤的长度的量,以产生其传播时间基本上等于要仿真的光纤的部分的输出光信号。 移位寄存器可以在任何点被抽头以获得延迟与所选择的光纤段对应的期望量的输出。

    • One embodiment of a picking tool for an automated library of disk drives has an electromagnet, a tapered hole, and a ventilation system. The ventilation system has a box fan with an impeller for moving air through ducting located within the picking tool. The ducting includes a vents located adjacent to one surface of the picking tool. The picking tool is designed to work in conjunction with a disk drive carrier having a front bezel equipped with a tapered guide pin that is complementary to the tapered hole, and vent ports. The guide pin provides alignment between the carrier and the picking tool. The automated disk drive library has a rack with drawers for containing the carriers. The picking tool is mounted to a robotic arm for selectively engaging and interfacing with the carriers. After the picking tool aligns with a desired carrier, the picking tool moves toward the carrier to insert the guide pin into the tapered hole. The disk drive is ventilated by activating the ventilation system to force air through the ducting and vents to cool the disk drive via the vent ports. Ventilation may be performed regardless of the operational status of the disk drive.

    • An apparatus, system, and method are disclosed for aberration compensation. In one embodiment, a first compensation lens used in conjunction with a second compensation lens to produce a conical beam used to read from, or write to, an optical medium. An Nth order compensation equation is used to optimize aberration errors associated with accessing the optical medium. The present invention may include a displaceable focus lens positioned relative to an optical medium. The focus lens may be displaced when the conical beam's focal length is adjusted. A displacement equation is presented to determine the preferred placement of the focus lens. By compensating for aberration, read/write errors may be reduced while accessing optical media thus increasing system robustness and facilitating the use of additional layers on optical media.
