International Classification:

G11B 5/596

US Classification:

360 7705

Abstract:

A method for writing servo onto a disk of a hard disk drive with a servo writer. The method includes writing a plurality of spiral servo signals onto a disk. The spiral servo signals include a plurality of short spirals separated by unequal distances. The short spirals are detected by determining the unequal distances and used to write a plurality of servo patterns. The unequal distances provide information of the short spirals at different quadrants of the disk. The distances between a bank of odd short spirals is different than a bank of even short spirals which allows the servo writer to determine whether the bank is odd or even without switching banks. Either the even or odd bank of short spirals can be used to locate a starting reference point from which the servo writer can count spirals and write A, B, C and D servo bursts.

US Classification:

428402, 428403, 428404, 428405, 428406, 428407, 977811

Abstract:

Ligand compositions for use in preparing discrete coated nanostructures are provided, as well as the coated nanostructures themselves and devices incorporating same. Methods for post-deposition shell formation on a nanostructure, for reversibly modifying nanostructures, and for manipulating the electronic properties of nanostructures are also provided. The ligands and coated nanostructures of the present invention are particularly useful for close packed nanostructure compositions, which can have improved quantum confinement and/or reduced cross-talk between nanostructures. Ligands of the present invention are also useful for manipulating the electronic properties of nanostructure compositions (e. g. , by modulating energy levels, creating internal bias fields, reducing charge transfer or leakage, etc. ).

US Classification:

340/005220, 340/005600, 340/005700

Abstract:

A security system includes an electronic lock and an electronic key. The electronic key holds identification data that notifies the lock of the key's functional type and the locks that the key is authorized to open. In one embodiment, circuitry in the lock checks whether an inserted key holds an access code that is more recent than a corresponding access code stored in the lock, indicating that the data on the inserted key is more current than the data stored in the lock. The lock is then automatically reprogrammed with the data stored in the inserted key.

International Classification:

H01L 21/00

US Classification:

136250000, 438063000

Abstract:

Devices, compositions and methods for producing photoactive devices, systems and compositions that have improved conversion efficiencies relative to previously described devices, systems and compositions. This improved efficiency is generally obtained by one or both of improving the efficiency of light absorption into the photoactive component, and improving the efficiency of energy extraction from that active component.
