Filed:

Jan 6, 2003

Appl. No.:

10/337081

Inventors:

Jian Lin - Sunnyvale CA, US

International Classification:

H01S003/30
H01S003/10
H01S003/083

US Classification:

372 6, 372 94, 372 20

Abstract:

A fiber-based ring cavity tunable laser is disclosed in this invention that has full range high speed tuning achieved by combining a optical tunable filter with a period comb-shaped filter with central wavelengths anchored on International Telecommunication Union (ITU) grids. By using segments of dispersion managed fibers with predefined segment lengths the group delay differences are also reduced. The temperature sensitivity of optical transmission is also reduced by arranging the longitudinal axis of different segments of the optical fibers to orient with a relative angular difference, e. g. , with an angular difference of ninety degrees.

International Classification:

G01M 3/02

US Classification:

73 37

Abstract:

A test station for testing polishing heads for planarizing semiconductor wafers and other substrates has a head positioning control system which can precisely position the polishing head at one of many electronically controlled positions above the test station platform. The test station may also include a lateral carriage assembly which supports the polishing head above a base plate of the station and permits the polishing head to be moved in a gliding motion above the surface of the test station test wafer. A sensor senses when the carriage of the assembly is moved from a load position. In response, the test station controller causes a vertical actuator to lift the head mount in the vertical or Z direction. In this position, there is sufficient clearance for the polishing head being carried by the carriage to slide under the head mount and into position for mounting to the head adapter. The carriage includes a carriage plate, the top surface of which defines a generally disk segment shaped recess which is sized and shaped to receive the bottom of a polishing head of a first size, such as a polishing head adapted to hold 300 mm semiconductor wafers for polishing, for example.

Abstract:

An in-phase and guadrature (IQ) imbalance error-correction method includes estimating, on the basis of a constellation error in a received orthogonal frequency division multiplexing (OFDM) signal, an extent of an I/Q imbalance error, caused by direct IQ conversion of the received OFDM signal. On the basis of that extent, an equalizing transformation that reduces that error is estimated.

US Classification:

451398, 451 41, 451285

Abstract:

A retaining ring can be shaped by machining or lapping the bottom surface of the ring to form a shaped profile in the bottom surface. The bottom surface of the retaining ring can include flat, sloped and curved portions. The lapping can be performed using a machine that dedicated for use in lapping the bottom surface of retaining rings. During the lapping the ring can be permitted to rotate freely about an axis of the ring. The bottom surface of the retaining ring can have curved or flat portions.

US Classification:

320132, 324427

Abstract:

An embodiment contemplates a method for estimating a capacity of a battery. A state of charge is determined at a first instant of time and at a second instant of time. A difference in the state of charge is determined between the first instant of time and the second instant of time. A net coulomb flow is calculated between the first instant of time and the second instant of time. The battery capacity is determined as a function of the change in the state of charge and the net coulomb flow.
