Abstract: The present invention is concerned with a method and a kit for detecting an interaction between a first membrane bound test protein or fragment thereof and a second test protein or fragment thereof which is either membrane bound or soluble with an in vivo genetic system based in yeast, bacterial or mammalian cells. The system makes use of the reconstitution of the split ubiquitin protein.

Abstract: A disk drive internal temperature control system is disclosed. The internal temperature control system includes a disk drive temperature monitor for determining a temperature of the disk drive and for providing a measure of the temperature of the disk drive and a disk drive temperature manager for managing the temperature of the disk drive based on the measure of the temperature of the disk drive. A temperature control component controls the temperature of the disk drive.

Abstract: A mobile computing hard disk drive has both a flash memory device and a DRAM device, with the HDD controller managing data storage between disk, DRAM, and flash both when write requests arrive and when the HDD is idle to optimize flash memory device life and system performance.

Abstract: Tilt between a head stack and its associated disk stack in a hard disk drive (HDD) is measured by determining the deviation of a target head from its expected position (based on the position of the current head) each time electrical contact is switched from the current head to a target head. A running average tilt value is stored and used to modify the logical seek distance used in a Rotational Position Optimization (RPO) algorithm to better order I/O requests in a queue. Also, the running average tilt value can be used by the servo to pre-position the target head before electrical contact is made with the target head, to improve speed of operation.

Abstract: A generic manufacturer-independent method to produce a metric of hard disk drive performance includes executing accesses from a reference sector on disk to several equidistantally-spaced target sectors, and recording the times of the accesses. These times are then ordered and used to generate shortest access times along with probabilities of achieving those access times, losing a disk revolution while accessing the target sector, and losing a disk revolution while executing a read/write operation.
