Title: Phosphodiesterase-v modulator drugs and their uses
Inventor: ZHU YAN
IPC: A61K47/48
Filed: 1999-06-07
Abstract: This invention relates to novel multibinding compounds that bind to the enzyme phosphodiesterase V (PDE V) and modulate its activity. The compounds of this invention comprise 2-10 PDE V modulator (particularly inhibitor) ligands covalently connected by a linker or linkers, wherein the ligands in their monovalent (i.e., unlinked) state bind to a PDE V enzyme. The manner of linking the ligands together is such that the multibinding agents thus formed demonstrate an increased biologic and/or therapeutic effect as compared to the same number of unlinked ligands made available for binding to PDE V. The invention also relates to methods of using such compounds and to methods of preparing them. The compounds of this invention are particularly useful for treating diseases and conditions of mammals that are mediated by PDE V.  Accordingly, this invention also relates to pharmaceutical compositions comprising a pharmaceutically acceptable excipient and an effective amount of a compound of this invention.

Title: Flexible access authorization feature to enable mobile users to access services in 3g wireless networks
Inventor: TORABI MOHAMMAD
IPC: H04M3/42
Filed: 2000-12-21
Abstract: The flexible access authorization feature for wireless telecommunication systems enables network operators and/or service providers to dynamically authorize a user to receive services for which the subscriber has not previously subscribed or which are not supported in the user's home network. This is accomplished by enabling a user to expand and contract their portfolio of available communication services on an as needed basis to enable wireless users to use their user mobile terminals and obtain the services which they need, regardless of the user's location in the wireless communication network and regardless of the present set of services for which the user is authorized. The flexible access authorization feature is accomplished by real time interaction among the relevant functional entities of the wireless telecommunications system to obtain new or additional user information to execute the flexible access authorization logic to decide on access authorization to a selected service. The flexible access authorization logic can reside in any of a number of network entities and can examine a number of conditions to determine access authorization for a user with respect to a selected service, including: time-dependency, location-dependency, account billing limitations, and other factors.

Patent CA-2329984-A1 (CA)
Title: Strain relieved leading-in connection for signal cables with twisted wire pairs
Inventor: NIELSEN ULRIK
IPC: H01R13/58
Filed: 1999-04-23
Abstract: In the termination of signal cables with two or more wire pairs, it is customary to effect a clamping of the cable in order to relieve the strain on the wires themselves and the terminal connections.  This, however, results in an uncontrollable re-arrangement of the wire pairs with associated interference between them. With the invention, this is avoided in that the termination or the strain-relieving element is configured with mutually separated lead-in passages for the individual wire pairs, and with associated clamping means for each of the wire pairs led through the passage. There is hereby achieved a well-controlled electrical separation between the wire pairs, and also an improved mechanical strain relief, i.e. by a primary clamping of the wire pairs themselves. By using a wedge part for insertion into the end of the cable, it can be ensured that the wire pairs extend from the end of the cable in an evenly inclining manner, whereby signal reflections from the area will be minimised.

Patent CA-2339515-A1 (CA)
Inventor: UPPALA SATHYADEV VENKATA
IPC: H04B1/7143
Filed: 2001-03-05
Abstract: Base station identification and downlink synchronization are realized by employing pilots including known symbols transmitted at prescribed frequency tones in individual ones of prescribed time intervals. Specifically, the symbols used in the pilots are uniquely located in a time- frequency grid, where the locations are specified by periodic pilot tone hopping sequences. In a specific embodiment of the invention, a period of a pilot tone hopping sequence is constructed by starting with a Latin-square based hopping sequence, truncating it over time, and possibly offsetting and permuting it over frequency. Particular examples of pilot tone hopping sequences are parallel slope hopping sequences in which the periodicity of the sequences is chosen to be a prime number of symbol time intervals. In another embodiment of the invention, a notion of phantom pilots is employed to facilitate use of various system parameters while accommodating the above noted pilot tone hopping sequences. That is, based on system considerations the frequency range of the above generated pilot tone hopping sequences exceeds the available bandwidth of a particular system, which would be a problem. This problem is overcome by truncating the pilot tone hopping sequences whenever the tone frequency exceeds the bandwidth, that is, designating these tones as phantom pilot tones and not transmitting them.
