Abstract: Servo circuitry (325) is disclosed that is configured to operate with a magnetic disk drive system. The servo circuitry is comprised of a first servo detector system (401), a second servo detector system (402), and a comparator (416). The first servo detector system and the second servo detector system each receive samples, taken from a read signal, that include servo data. The first servo detector system compares the samples to a plurality of servo codes to generate a first selected code. The second servo detector system compares a first shifted version of the samples to the plurality of servo codes to generate a second selected code. The comparator receives the selected codes and selects one of the selected codes. The selected code represents the servo data (359). The servo circuitry could also include a third servo detector system (403) that operates on a second shifted version of the samples. Alternatively, the first servo detector system, the second servo detector system, and the third servo detector system could each be programmed with different servo codes. The first servo detector system compares the samples to a plurality of first servo codes. The second servo detector system compares the samples to a plurality of second servo codes. The third servo detector system compares the samples to a plurality of third servo codes. The second servo codes and the third servo codes are shifted versions of the first servo codes.

Title: Doppler spread/velocity estimation in mobile wireless communication devices and methods therefor
Inventor: MALLETTE ALEXANDRE
IPC: H04L27/06
Filed: 2002-05-02
Granted: 2004-05-01
Abstract: A method for estimating Doppler spread in mobile wireless communication devices, for example in CDMA or W-CDMA cellular communication systems, with improved noise immunity. The Doppler spread estimation is based on an estimated value of an autocorrelation or autocovariance at a first lag (210) and at a second lag (220), the magnitude of which is greater than the first lag. A first ratio is determined (250) between a first difference (230) and a second difference (240). The estimated Doppler spread is generally proportional to a square root (260) of the first ratio, and is scaled (270) by a multiplicative factor that depends on whether the estimated function is an autocorrelation or autocovariance function.

Title: Optical-mechanical feature fabrication during manufacture of semiconductors and other micro-devices and nano-devices that include micron and sub-micron features
Inventor: MEI PING
IPC: G03F1/08
Filed: 2002-11-26
Granted: 2007-01-21
Abstract: A method and system for fabricating micron and sub-micron-sized features within a polymer layer (402, 502) of a nascent semiconductor device or other micro-device or nano-device. Small features are directly imprinted with an optical-mechanical stamp (403, 503.) having corresponding intrusions (204-207). Large features are created by exposing the surface of selected areas of the polymer surface (411, 520) to UV radiation by transmitting UV radiation through the optical-mechanical stamp to chemically alter the polymer, allowing either UV-exposed or UV-shielded areas to be removed by solvents. Thus, described embodiments of the present invention provide for a partially transparent imprinting mask that employs purely mechanical stamping for fine features and lithography-like chemical polymer removal for large features.
