Abstract: The present invention provides a method of describing defects that requires less memory space than conventional methods. Entries of a first defect table are sorted according to the type of track layout, or zones. They are then grouped into clusters. Each cluster is characterized by a set of new parameters, including a starting sector, a scratch parameter, a span parameter, and an angle parameter. The new parameters are stored in a second table, replacing the corresponding entries in the first table. In this manner, a single entry in the second table replaces one or more entries in the first table with one entry in the first table.

In one embodiment, the pull-lever actuator includes a pull grip, a de-latching arm, and an electromagnetic interference (EMI) shield with grounding tabs to couple to the cage or module receptacle to connect to ground. The pull-lever actuator makes it easy to de-latch and unplug a fiber optic module from the cage or module receptacle.

Abstract: The present invention relates to a device for preparing assay samples using a number of microscope slides. Each slide has a number of assay reaction surface locations spaced on the planar surface of the slide. In preferred embodiments, the device comprises, in part, a microscope slide holder that has the exterior dimensions of a SBS standard microplate, such as a 96 well plate. The device accepts conventional microscope slides equipped with sixteen microarray surfaces spaced nine millimeters apart on center, or four for a 96 well plate. Individual chamber plates are placed on top of the slides, creating an individual well above each assay reaction surface location. In preferred embodiments, each assay reaction surface location can comprise a microarray of multiple reactive sites. Thus, parallel processing can be done of samples for genomic or proteomic profiling.

Abstract: A high power driver system has a predetermined number of driver modules for driving a high power device such as a laser-emitting device. Each driver module has a driver circuit and a corresponding feedback circuit. The driver circuits respectively generate driving currents, and then the driving currents are collected to drive the high power laser-emitting device or other high power devices. In addition, these feedback circuits of the driver modules receive the same detection signal that represents the output power of the high power laser-emitting device. Then, each feedback circuit responds to the same detection signal to generate a feedback signal, respectively, which makes the corresponding driver circuit carry out a feedback action for adjusting the driving currents.

Abstract: A system for adapting head switching sequence in a disc drive includes a method of measuring the time duration for a head switch operation and the time duration of a track switch operation. The system compares the two time durations to determine whether head switching or track switching should be utilized within a zone of tracks on the surface of the data disc. Track switch time durations and head switch time durations may be averaged within a zone and the averages compared to determine whether to use head switching or track switching.

Abstract: A method of storing values that involves splitting each value into a n-bit value and an overflow value, and storing, in a main table, the n-bit values in order of increasing magnitude of the values. For each overflow value, the position of the smallest n-bit value is stored in an overflow table. To retrieve a value, the position of the corresponding n-bit value is compared to the positions stored in the overflow value to determine the overflow value of the n-bit value. The actual value is then obtained from the n-bit value and its overflow value.

Abstract: A disc drive typically contains at least one disc which is divided into sectors. The method of eliminating reassignments involves copying data stored at one sector (referred to as a moving sector) to another sector (referred to as a moving spare), and assigning the logical address associated with the moving sector to the moving spare. The elimination process is repeated until the reassignments are eliminated. Verification of the data copied is conducted to ensure data integrity. Furthermore, the elimination process is preferably executed only when the disc drive is in an idle mode. Records are kept and updated as the process is carried out so that the process can be continued even if interrupted.
