Patent CA-2439792-C (CA)
Title: Phase transfer of nanoparticles
Inventor: GITTINS DAVID
IPC: C09D1/00
Filed: 2001-11-23
Granted: 2008-04-22
Abstract: The present invention relates to phase transfers of nanoparticles and catalysis using nanoparticles.      Transfer of nanoparticles from an organic solution into an inorganic solution, in particular an aqueous solution, is made possible by adding a generic class of substances, in particular the commercially available 4-dimethylaminopyridine, hereinafter referred to as DMAP for short, e.g. present in aqueous solution, to the organic solution in a sufficient amount. This measure results in the nanoparticles going over in a 1-step process from the organic phase (in each case at top) into the inorganic phase (in each case at bottom) in the sample container without any further action being necessary.

Abstract: A cutting apparatus has been produced that eliminates the common occurrence of raw razor blades contaminating everything from food and food products to garbage cans to shelves in retail stores. Furthermore, the cutting apparatus comprises a guard assembly that, when activated, opens the blade cover and allows only one cut to be made with the exposed blade before the unidirectionally-locking blade cover snaps back over the exposed blade, thus preventing laceration-related accidents. In addition, if the operator continues to activate the guard assembly (squeezing, pulling and/or depressing the trigger and/or releasing the trigger and continuing to hold it in the released position during and after the cut has been made) after one cut has been made with the exposed blade, the unidirectionally-locking blade cover will still snap back over the exposed blade, despite the position.of the trigger. Once the blade cover snaps back over the exposed blade, the locking device is activated and acts to hold the blade cover securely over the blade until the blade assembly is further activated by releasing the trigger from the depressed position and depressing, releasing, squeezing or pulling the trigger once again.

Abstract: The present invention provides methods and devices (100) for grasping (106), and optional repositioning and fixation of the valve leaflets (LF) to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation (115).

Title: The copy protection of optical discs
Inventor: BASILE CARMEN LAURA
IPC: G11B20/10
Filed: 2005-04-27
Granted: 2010-11-09
Abstract: Subversive DSV (SDSV) sequences of data symbols having a large absolute value of DSV are extremely valuable in the copy protection of optical discs as they can induce uncorrectable read errors. However, very few SDSV sequences of data symbols can be found in multimodal codes such as Eight-to-Sixteen Modulation (ESM) utilised in DVDs. It is required to select data symbols, for encoding using a multimodal code, which are capable of forcing an encoder to produce at least one subversive sequence of code words. A possible code word for a data symbol is selected if the code word has a large absolute value of DSV and there are no alternative code words, or all alternative code words are equivalent, or all alternatives except one are ruled out by RLL rules.

Abstract: The present invention is directed to automating the sending of campaign messages (260) in computing environments. Campaign scores (280) are determined for messaging campaigns (260) and eligible recipients are assigned to campaigns with a higher score. More specifically, eligible recipients are assigned to a particular messaging campaign if the campaign is the "best"  campaign for each eligible recipient based on the campaign score.  Additionally, a portion of the eligible recipients are reserved as a control group for each campaign. After campaign messages have been sent out to assigned recipients, the behavior of the recipients who received campaign messages and the behavior of the control group members are differentiated to update the campaign's score (280). Continually updating campaign scores (280) makes it possible to continually update which campaign is best for a particular recipient.
