Title: Phase locked loop for an ofdm system
Inventor: GUPTA ALOK KUMAR
IPC: H04L27/26
Filed: 2004-04-06
Abstract: Techniques are provided for tracking residual frequency error and phase noise in an OFDM system. At a receiver, each received OFDM symbol is transformed with an FFT to obtain received modulation symbols, which are serialized. A  phase locked loop (PLL) operates on the serialized received modulation symbols and provides an independent phase correction value for each received modulation symbol. Each received modulation symbol is corrected with its own phase correction value to obtain a phase-corrected symbol. The phase error in each phase-corrected symbol is detected to obtain a phase error estimate for that phase-corrected symbol. The phase error estimate for each phase-corrected symbol is filtered (e.g., with a second-order loop filter) to obtain a frequency error estimate, which is accumulated to obtain a phase correction value for another received modulation symbol. The phase-corrected symbols are not correlated because independent phase correction values are used for the received modulation symbols.

Title: System and method for automatic processing of endoscopic images
Inventor: PEARSON PHILIP
IPC: G06F40/00
Filed: 2004-05-14
Abstract: A system and method for enabling the automatic setting of a mask for displaying live endoscopic images on a monitor device. An imaging node processor selects a pre-determined mask setting based on an automatically detected solid state imager (CCD) type when connected to the video processor, and a selected magnifying ration. Based on this information, a mask pattern is automatically generated in a main memory. A merge function enables to mask to be displayed with cutout portions where information including, live or frozen image, thumbnail image associated with a static image capture, and a patient demographic information is displayed. The user may select the frame coordinate locations corresponding to the corners of the live viewable area, captured image display and other system and demographic information to be displayed.  Further, while the system is configured to include pre-defined masks, users are additionally able to create additional masks or modify the system-defined masks. The user can associate a mask to one or more scopes or video chip (imager) types.

Title: Method of forming a scribe line on a passive electronic component substrate
Inventor: SWENSON EDWARD J
IPC: H01L21/50
Filed: 2004-07-09
Abstract: A method of forming a scribe line (36) having a sharp snap line (44) entails directing a UV laser beam (14) along a ceramic or ceramic-like substrate (10) such that a portion of the thickness (24) of the substrate (10) is removed.  The UV laser beam forms a scribe line in the substrate in the absence of appreciable substrate melting so that a clearly defined snap line forms a region of high stress concentration extending into the thickness of the substrate. Consequently, multiple depthwise cracks propagate into the thickness of the substrate in the region of high stress concentration in response to a breakage force applied to either side of the scribe line to effect clean fracture of the substrate into separate circuit components. The formation of this region facilitates higher precision fracture of the substrate while maintaining the integrity of the interior structure of each component during and after application of the breakage force.

IPC: B61B12/10
Filed: 2006-04-20
Abstract: Simplified regulation and balancing system applicable to cableway plants, of the continuous or to-and-fro type, equipped with two hauling cables functioning in parallel.      In a system according to the invention, the two cables are moved by distinct pulleys with separate winches; the kinematic chains of the two winches however are connected to each other by a device which is structurally similar to a car differential, whose outer box is kept blocked during normal functioning. In this way, the two winches are mechanically constrained and can rotate only at the same speed.      By rotating the differential box with an external system, a corresponding difference in the rotation rate is actuated between the two motor shafts; the rotation can take place, for example, with a small balancing motor-reducer which activates a toothed crown integral with the box.
