Title: Method and Apparatus for Exchanging Administrative Information Between Local Area Networks
Inventor: DESAI BHUPESH JAYANT
IPC: H04Q7/34
Filed: 1996-02-07
Abstract: The system of the invention has particular application to a wide area network (WAN) where call routing information often changes in one local area network (LAN) (e.g. a switching system) while other LANs (e.g. cellular communication systems) are unaware of the changes. Because of the heavy flow of traffic in such networks, the minimization of administrative traffic data is desirable. The invention solves the need for constant updating and auditing of the LANs in the WAN. One LAN is considered the master LAN for a given parameter and contains an accurate directory of administrative data for that parameter. Each of the other LANs operate on the assumption that the administrative or directory information it contains is correct. If this assumption is wrong for a particular parameter and a LAN contains incorrect information, in response to a communication to or from the LAN, the system: 1) recognizes that the information relating to the parameter is incorrect; 2) determines the correct information and completes the communication based uponthe correct information; and 3) updates the LAN with the correct information from the master LAN such that the next time the same communication is attempted the LAN has the correct information. In this manner, the LANs are updated on a need to know basis only after an actual communication is attempted thereby eliminating the constant transmission of administrative information between the LANs that exists in the prior art systems.

Title: Internal standards for quantitative competitive pcr
Inventor: COLLU ROBERT
IPC: C12Q1/6851
Filed: 1996-10-24
Abstract: The present invention relates to a method for constructing  internal  standards  used  in  competitive polymerase chain reaction  (PCR)  for determining the amount of a target nucleic acid sequence in a sample. The method comprises the  steps of  a)  digesting the cloned target nucleic acid sequence with a cohesive-end generating  restriction  endonuclease  b)  filling  the restriction endonuclease cohesive-ends of step a) by Klenow fragment of DNA polymerase;  and c)  blunt-end ligating the fragment of nucleic acid of step b) to form the  internal  standard.    The  internal  standard nucleic acid sequence differs from the target nucleic acid  sequence  such  that  a  restriction  endonuclease recognition site is destroyed by adding sufficient con-tiguous bases to the target nucleic acid sequence such that the size difference between the target nucleic acid sequence and the internal standard nucleic acid sequence can be detected by gel electrophoresis.
Patent CA-2190915-A1 (CA)
Title: High efficiency polarization diversity receiver system
Inventor: HALL DAVID B
IPC: H04B10/61
Filed: 1996-11-21
Abstract: A polarization diversity receiver system for yielding multiple heterodyne optical output signals from an incident optical beam having a p-polarized component and an s-polarized component comprises first and second sequentially-arrayed polarizing beamsplitters, and three photodetectors, each of which receives a heterodyne optical signal. The polarization diversity receiver system tracks the largest of these three signals, and uses only this largest one for subsequent signal processing. There is a minimum for this largest signal that is dependent on the input polarizations of the two optical fields whose beat note is the heterodyne signal. Thus, the object is to maximize the minimum of this largest of the three heterodyne signals. The first polarizing beamsplitter ideally splits the incident beam into a transmitted beam portion including approximately 100% of the p-polarized component and approximately 33% of the s-polarized component, and a reflected beam portion including approximately 0% of the p-polarized component and approximately 67% of the s-polarized component. The reflected beam portion exits from the first polarizing beamsplitter as a first heterodyne optical output signal, and impinges on a first photodetector. The transmitted beam portion exits from the first beamsplitter, and then undergoes an effective 45O rotation of its polarization eigenstates around its axis of propagation, either prior to or during its passage through the second polarizing beamsplitter. The second beamsplitter splits the rotated transmitted beam portion into second and third heterodyne optical output signals, which respectively impinge upon second and third photodetectors.

Title: Method of and apparatus for transferring material from a bulk medium
Inventor: TAYLOR PETER JOHN
IPC: G03G21/12
Filed: 1995-05-26
Abstract: A method of depositing material on a surface (136) is described in which a bulk medium (for example ink 122) in the form of a composition of dispersed insoluble ma-terial (for example ink particles) and a sup-port medium is supplied to a cell (120). A movement of the insoluble material within the bulk medium is effected towards a trans-fer aperture (128) within the cell, thereby concentrating the insoluble material within the bulk medium.  Thereafter the insoluble material is removed from the concentration within the bulk medium through the aperture (128) and deposited onto the surface (136).

Abstract: Hockey tape is applied to the blade of a hockey stick in order to provide the blade with protection from continuos impact from the puck and to increase the hockey player's puck control. This invention, "Hockey Stick Wax", relates to a hockey equipment accessory which can be applied to both a hockey stick blade and the taped area of a blade in order to protect and enhance the properties of these areas by providing them with a moisture resistance barrier. The moisture resistant barrier, by not allowing water to be absorbed, increases the life of the hockey tape and also increases puck control by not allowing unwanted frost and snow to attach to the protected areas. The "Hockey Stick Wax" may also have a fragrance added to the formulation so that, when the "Hockey Stick Wax" is stored and kept in the hockey equipment bag, the pleasant scent of the fragrance, emitted by this product, can mask unpleasant scents like the ones which are commonly found in a hockey equipment bag.
