Title: Global navigation satellite system receiver with blanked-prn code correlation
Inventor: VAN DIERENDONCK ALBERT J
IPC: H04B1/10
Filed: 1998-06-25
Abstract: A GLASS receiver includes a subsystem that reduces the adverse effects of multipath signals on punctual and early-minus-late correlation measurements by making the correlation measurements using a "blanked-PRN code." The blanked-PRN code is all zeros except for adjacent positive and negative short pulses that occur at every code bit transition in a locally-generated PRN code. Using the blanked-PRN code, the receiver makes non-zero correlation measurements only near the code bit transitions in the local PRN code. If the local PRN code and the PRN code in the received GLASS satellite signal are closely aligned, the non-zero correlation measurements are made at the times of the bit transitions in the received PRN code. The contributions to the correlation measurements of the multipath signals that do not have bit transitions during the adjacent positive and negative pulses in the blanked-PRN code cancel when the correlation measurements are accumulated - since these multipath signals are constant during the pulse times. The GLASS receiver includes blanked-PRN code logic that produces the blanked-PRN code from the locally-generated PRN code. The blanked-PRN code logic thus produces a code that is zero-valued except for the adjacent pulses. Alternatively, the blanked-PRN code logic produces the zero-valued portions of the code by selectively disabling the blanked-code correlators in between the code bit transitions in the local PRN code. The result is the same, namely, a system that produces non-zero correlation measurements near the code bit transitions in the local PRN code.

Title: Method of making dispersion decreasing and dispersion managed optical fiber
Inventor: DOBBINS MICHAEL S
IPC: C03B37/012
Filed: 1997-02-11
Abstract: The invention is a method of making an optical fiber or cane (600) that has optical properties that vary axially. Core glass (100) and clad glass (200) are fed into a furnace to form the cane or fiber. The velocities of the feeding of the clad and core are controlled so that the total combined mass per unit time is constant. The diameter of the core (604) varies along the length of the fiber or cane in accordance with the control of the velocities. The variance in the core diameter results in the variance of the axial optical properties of the fiber or cane.

Title: Method and system for activity-responsive telemarketing
Inventor: PETTY DOUGLAS
IPC: G06Q30/02
Filed: 1998-12-04
Abstract: A method of alerting a telemarketing agent of a promotion  opportunity  in  response  to  activity  of  a potential  customer  browsing  a  public  server  and  an apparatus  for  monitoring  the  customer  activity  and alerting  the  telemarketing  agent  are  described.    The apparatus  includes  a  telemarketing  analysis  server, computer telephony hardware and a server for controlling the computer telephony hardware.   The apparatus further includes  software  on  the public  server  for  collecting data  relating  to  the  activity  of  potential  customers browsing the public server.   The data is  sent to the telemarketing  analysis  server  which  analyzes  it  to determine when a potential customer's activity satisfies a  predefined  criteria.    If  a  predefined  criteria  is satisfied,  an  alert  is  forwarded  to  a  telemarketing agent.     The  telemarketing  agent  may  approach  the potential  customer  in  order  to  promote  a  sale.    The approach  to  the  customer may be  a  text  message  that requests  whether  the  user would  like  assistance  or  a direct telephone call, depending on the circumstances and knowledge about the customer.   The customer may also be sent a message before the telemarketing agent is alerted. This permits the agent to spend all of his time fielding calls.  The advantage is the ability to contact potential customers at a time when they are aware of a product or service and interested enough to access a public server relating to the product or service.  A further advantage is that customer availability is assured and the public server  is  enabled  to  provide  interactive  personal contact.
Patent CA-2256166-A1 (CA)
Inventor: SCHNARR RAYMOND H
IPC: E05C17/60
Filed: 1998-12-16
Abstract: A check mechanism is provided to regulate door speed of a roller supported sliding door as the door is manually opened or closed.  The check mechanism includes an idler arm assembly attached to a door hanger with an idler roller attached to the idler arm assembly.  The check mechanism further includes a pivotable spring biased lever arm having two inclined ramp sections.  As the door slides, the idler roller contacts the lever arm.  The inclination of the ramp causes an increasing retardation force to be applied to the idler roller, thereby retarding the speed of the door. After the idler roller passes a point of maximum retarding force, the door becomes free wheeling until a second idler roller contacts the lever arm of a second checking mechanism which in turn slows the speed of the door.
