Patent CA-2536915-A1 (CA)
Inventor: BOUDREAUX CHAD P
IPC: A61B17/94
Filed: 2006-02-17
Abstract: A surgical instrument particularly suited to endoscopic use articulates an end effector by including a fluid transfer articulation mechanism that is proximally controlled. A fluid control, which is attached to a proximal portion, transfers fluid through the elongate shaft through a first fluid passage to a first fluid actuator that responds by articulating an articulation joint. Two opposing fluid actuators may respond to differential fluid transfer to effect-articulation. Thereby, design flexibility is achieved by avoiding the design constraints of transferring a mechanical motion through the tight confines of the elongate shaft sufficient to effect articulation.

Title: Watermark incorporation
Inventor: SIEBENHAAR FRANK
IPC: G10L19/00
Filed: 2005-03-11
Abstract: The invention relates to an inventive method for introducing a watermark into an information signal, according to which said information signal (12) is converted from a temporal representation (22) into a spectral or modulation spectral representation (30). The information signal is then manipulated in the spectral or modulation spectral representation (30) in accordance with the watermark (14) that is to be introduced, to obtain a modified spectral or modulation spectral representation. Finally, a watermarked information signal (16) is formed based on the modified spectral or modulation spectral representation. One advantage of the inventive method is that as the watermark (14) is incorporated into or derived from the spectral or spectral modulation representation or domains, traditional correlation attacks that are used on watermarking methods based on spread spectrum modulation do not necessarily reach their target.
