Title: Simplified scrambling scheme for satellite broadcasting systems
Inventor: CHEN ERNEST C
IPC: H04L27/36
Filed: 2004-08-27
Abstract: A simplified scrambling scheme that unifies all signals of a satellite broadcasting system, including frame header (404), frame body (402) and pilot symbols (408) with a common reference phase. This results in the simplification and increased flexibility of the receiver front-end design without affecting the overall system performance. In many current communications systems with frame headers and pilot symbols, the phases of frame headers and pilot syrnbols are not designed to be aligned with any constellation points of the modulated data from the frame body. This scrambling scheme takes into account possible impact due to irregular phase changes between frame headers/pilot symbols and modulated data.

Abstract: An insulated rail joint assembly comprises a rail with a thick web section, held in place by joint bars and secured with electrically isolated fasteners. The joint bars have non-uniform cross-sections, being shaped with a thicker midsection area and thinner ends.  Electrically non-conductive shear pins through the rail and the joint bars provide shear resistance and prevent glue bond failure. High strength cloth between the rail ends and between the rail and the joint bars strengthens the joint, as does an insulating rail clip resiliently fastened to an insulating tie plate, which itself may be supported on a cross tie of increased width.

Abstract: A surgical stapling and severing instrument enables minimally invasive surgical procedures by having upper and lower jaws (i.e., anvil and staple channel) that are positioned with an elongate shaft and handle through surgical openings, and in particular through a cannula of a trocar. A pair of fluid actuator bladders (lift bags) are positioned in the staple channel beneath a proximally projecting lever tray so that transfer of fluid from the handle causes closing and clamping of the anvil. The bi-directional fluid control may be mechanically produced at the handle or by activating an electroactive polymer actuator. Once firing is sensed, an EAP plunger in a medical substance syringe inserted into the elongate shaft is activated to dispense a medical substance (e.g., anesthetics, adhesives, cauterizing substances, antibiotics, etc.) and is guided along a firing bar to a cutting surface of an E-beam placing the substance on tissue as severed.

Abstract: At least one alerting layer of a different color than a tire surface is divided into a rubber layer of the tire, in accordance with a safe abrasion condition of the tire, wherein a default distance of a lowest alerting layer to the tire surface is less than a depth of tire tread. Before the tire tread is worn out, the alerting layer of a default color will be emerged at a part of the tire that is abraded, due to a different extent of abrasion, which facilitates a consumer to check a degree of safety of the tire by oneself by a direct visualization method, and can prevent unworthy practicers to trick the consumer to replace the tire, while it has not achieved a standard of abrasion.

Abstract: A device and method for the lubrication of teeth (103) in a meshing gear (100). A plurality of teeth (103) are formed about a, periphery of a toothed wheel (102). Each tooth (101) is defined by a root portion (106), an involute profile portion (108), and a minimal stress portion (110). The device and method includes the formation of a plurality of fluidic passages (120), each including an inlet (122) and an outlet (124), in fluidic communication with a lubricant (119) and the minimal stress portion (110) of at least one (101) of the plurality of teeth (103).
