Inventor: CARRARO SILVANO
IPC: A44C5/10
Filed: 1996-08-29
Abstract: The watchband comprises for instance three rows of metal chain links. The chain links of the first central row (1, 1' etc.) are offset with respect to the chain links of the other two rows (2, 2' etc.). Each chain link of the central row (1') can pivot with respect to the preceding chain link (1) and with respect to the following chain link (1'') about pins (3) linked to the chain links of the lateral rows. Stop elements, for instance other pins (4, 4') also linked to the chain links of the lateral rows, restrict the pivoting angle of the central chain links about the first pins (3). The chain links are removable for adjusting the length of the watchband. The advantages are ergonomic and aesthetic. The invention avoids the skin being pinched or hairs being pulled. It also reduces the wear of the chain links and allows good control of the curve of the watchband, and of the interstices between successive chain links.

Title: Contrast-enhanced diagnostic imaging method for monitoring interventional therapies
Inventor: DUNHAM STEPHEN O
IPC: A61K49/06
Filed: 1998-09-24
Abstract: The present invention relates to a contrast-enhanced diagnostic imaging method for monitoring the efficacy of interventional therapies.  The contrast agents useful in this method comprise an image-enhancing moiety (IEM) and a state-dependent tissue binding moiety (SDTBM).  These contrast agents exhibit state-dependent binding to one or more components of a targeted tissue or tissue component and provide a detectable change in the signal characteristics of the agent once bound to the targeted tissue. As a result, these agents exhibit a binding affinity for, and thus image contrast of, the targeted tissue which changes as the tissue-state changes during therapy.
Patent CA-2312189-A1 (CA)
Inventor: SOLHEIM ALAN G
IPC: H04B10/275
Filed: 2000-06-23
Abstract: A filter topography is possible that can reduce the overall cost of a single Optical Add-Drop Multiplexer (OADM) or a series of OADMs that are within a network. The key is to have one of the wavelengths of a WDM signal being input to a filtering apparatus empty. The filtering apparatus can then with a reduced cost filter the received WDM signal such that a channel at a wavelength adjacent to the empty wavelength is removed and a channel is inserted at the previously empty wavelength. In one implementation of this topology within an OADM, a single filter can be used to perform both filtering operations due to the empty wavelength ensuring no corruption of the removed channel at the adjacent wavelength. In another implementation, the filtering operations are performed by two separate filters that each have asymmetrically reduced tolerances. In either case in which there is a reduced number of filters or reduced tolerances for those filters, a reduction in cost will be found.

Title: Wireless mobile call location and delivery for non-geographic numbers using a wireline ssp+scp/wireless hlr interface
Inventor: HOWE WALTER WESLEY
IPC: H04Q3/00
Filed: 2000-06-29
Abstract: A system and method is provided for establishing a call to a wireless directory number (982) which is either a non-geographic directory number or a non--dialable directory number. A call is initiated from a wireline telephone (155) to a geographic-based local access directory number (994, 996). An originating switching node (810) recognizes the local access directory number (994, 996) as an AIN trigger, and thereafter identifies a signaling node (820) that is associated with the dialed local access DN (994, 996). The signaling node (820) sends a location request that includes the local access DN (994, 996) to an HLR (130). The HLR (130) obtains the wireless DN (982) from an internal database (990) in which the wireless DN (982) is associated with the local access DN (994, 996). The HLR (130) utilizes the wireless DN (982) to receive a temporary local directory number (TLDN) from visitor location register (140). The HLR (130) associates the TLDN with the local access DN (994, 996) and subsequently forwards the TLDN to the signaling node (820), which in turn relays the TLDN to the originating switching node (810). The call connection is thereafter established directly from the originating switching node in the end office to a visited cellular switch using the TLDN.
