International Classification:

G11B 2102

US Classification:

360 75, 360 44, 360 48, 360 53, 360 7703

Abstract:

A system and methods for providing offset information on a storage medium are provided by writing at least one unalterable mark on the storage medium during a manufacturing formatting process. The unalterable mark(s) are variably offset from a fixed position. The amount of offset represents a first source of unique information.

International Classification:

G06F 1216

US Classification:

711162, 711141, 707202, 707204, 714 54

Abstract:

Data on a master is read into a master image file, and the master image file is manipulated to include a benchmark comprising tracking and verification information tied to at least a portion of the master image file. Thus, a copied-to storage media as copied from the master image file also includes such benchmark, a data alteration of the master image file causes a mis-match with regard to the benchmark in such master image file, and a data alteration of the copied-to storage media also causes a mis-match with regard to the benchmark in such storage media as copied from such master image file. The benchmark may include a part identifier and a security identifier.

International Classification:

G06F001/24

US Classification:

713193, 713200, 713201

Abstract:

A system and method are provided wherein digital data representing content and associated license rights may copied to a storage medium, such as a removable storage medium, whereby the serial number of the copied-to storage medium is integrated into the licensing scheme utilized to secure the digital content. As a result, the digital content is pre-authenticated and bound to the copied-to storage medium, obviating the need to access a network or other location for access to the protected content.

International Classification:

H04B 17/02

US Classification:

455139, 455118, 455130, 455131

Abstract:

Coherent detection of a received EM signal using universal frequency translation (UFT) is described herein. The received EM signal is sampled according to a sub-harmonic LO signal, where the LO signal is in frequency and phase coherence with the received EM signal. The coherent receiver includes a down-converter/demodulator and a synthesizer/loop filter that are both implemented using UFT technology. The down-converter/demodulator samples the EM input signal using a UFT module according to the coherent sub-harmonic LO signal that is generated by the synthesizer/loop filter. The synthesizer/loop filter generates the coherent LO signal using a phase detector, a loop filter, and an up-converter. The phase detector and up-converter are implemented using UFT modules.

H04L 27/22

US Classification:

375316, 375260, 375324

Abstract:

A universal frequency translation module (UFT) frequency translates an electromagnetic (EM) input signal by sampling the EM input signal according to a periodic control signal (also called an aliasing signal). By controlling the relative sampling time, the UFT module implements a relative phase shift during frequency translation. In other words, a relative phase shift can be introduced in the output signal by sampling the input signal at one point in time relative to another point in time. As such, the UFT module can be configured as an integrated frequency translator and phase-shifter. This includes the UFT module as an integrated down-converter and phase shifter, and the UFT module as an integrated up-converter and phase shifter. Applications of universal frequency translation and phase shifting include phased array antennas that utilize integrated frequency translation and phase shifting technology to steer the one or more main beams of the phased array antenna.

International Classification:

H04B 10/06

US Classification:

398202, 398204

Abstract:

A method and system for converting an optical signal to electrical information signals, including demodulated baseband information signals and modulated baseband signals at multiple harmonics. In an embodiment, the optical information signal is amplitude modulated with information. The method converts an optical signal to electrical charge, accumulates the electrical charge, and periodically transfers the accumulated electrical charge to a storage device, whereby the periodically transferred electrical charge forms the electrical signals. An exemplary system includes an optical transducer and a universal frequency translator coupled to an output of the optical transducer. The optical transducer receives an optical signal and converts the optical signal to electrical charge. The universal frequency translator periodically transfers energy from the electrical charge and forms the electrical signals from the transferred energy. In an embodiment, the present invention converts an I and Q optical signal to electrical signals.
