    Abstract: 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.

    Abstract: A power saving method and apparatus while maintaining an operational or near-operational state for computer memory disk drives. A microprocessor implements microcode instructions to determine if a disk drive is inactive. This is done by checking a control unit through an interface to see if any files are currently opened or data is being transferred by the disk device. If no files are opened and/or no data transfers are occurring, the drive is considered inactive. If the inactive period continues for a period of time which is greater than a predetermined reference activity level, then actions are taken to reduce the rotational velocity of the drive spindle motor to its lowest operational level, or just below the lowest operational level without stopping the disk. The spindle motor is accessed by the microprocessor through a spindle motor control unit. In the case of a constant linear velocity disk drive, the spindle motor is indirectly controlled by the microprocessor sending a message to an actuator to move a data head to a track that is near the outer periphery of the disk medium. In order to maintain a constant linear velocity, the spindle control slows the angular velocity of the motor resulting in a reduction of power consumed. When it is necessary to access data again, the drive enters an active state and the head is moved by a microprocessor “seek” command. In the case of a constant angular velocity disk drive having selectable speeds, the microprocessor controls the motor speed directly. The microprocessor, upon determining that the disk has been inactive for a predetermined threshold period, selects a constant speed that is the lowest operation speed available. This results in a power saving mode being implemented for the disk drive The drive is returned to normal operational speed by a microprocessor “seek” command. For further savings, the motor is stopped or “spun down” when left inactive for a longer period of time.

    Abstract: In an optical data storage device for storing data on a removable optical disk in a continuous sequence of sectors or blocks, the input data buffer may be subject to under-run. An under-run detector is disclosed which is responsive to the buffered data comprising less than a sector of data for indicating an under-run, and a padding provider is disclosed which is responsive to the under-run indication for providing padding characters for formatting into sectors. The sectors may be provided with headers indicating the sectors as padding. A reading device for reading the data sectors and providing the data to a host detects padding and prevents the padding data from transmission to the host.

    Abstract: Using a graphical user interface (GUI), users manipulate, organize, classify, and/or arrange icons by having the icons bind (stick) to one another and be moved as aggregates. Icons sticky sites may be on icons, windows, or other graphical objects. For example, when an icon with a sticky site is dragged close to another icon with a sticky site, the icons bind together and are subsequently moved as one graphical unit. In some embodiments, a visual indication or binding is given. The icons may be unbound by pointing to an unbinder icon, or using a button sequence on the mouse of keyboard.
