Title: Method for the optimal resource allocation for the transport of variable-bandwidth data flows in atm networks, and cross-connect node utilizing the method
Inventor: CAPPELLARI ANTONIO
IPC: H04L12/56
Filed: 1995-05-31
Granted: 1999-12-21
Abstract: A flow of ATM cells to be cross-connected performs two consecutive passes through the connection network (PX) of a node. In the first pass the virtual channels of the input virtual paths (A, B, C) are distributed among intermediate virtual channel bundles (A'...C''') each with an overall peak bandwidth equal to that of the virtual path of origin of its contributing channels; between the first and the second pass, the virtual channels are cross-connected and the related cells are temporarily memorized, and at the same time the cell flow to be associated to an output virtual path is shaped; and in the second pass the virtual paths are cross-connected, Temporary memorization and shaping are accomplished in a device (SMS) connected between the outputs and the inputs of the connection network (PX) of the node.

Patent CA-2153941-C (CA)
Inventor: GOERING DOUGLAS J
IPC: E01C3/06
Filed: 1995-07-14
Granted: 1999-04-06
Abstract: A roadway for use on permafrost terrain is described together with methods of construction, the roadway generally including a porous embankment and a pavement structure disposed on the top of the embankment.  The embankment has a desired vertical separation between the bottom and the top of the embankment and comprises material of sufficient permeability to allow buoyancy-driven pore air convection to occur within the embankment when an unstable density stratification exists therein.  This unstable density stratification occurs in the winter months when a temperature differential between the top of the embankment and the ground adjacent the bottom of the embankment exists, whereby the roadway promotes natural convection within the porous embankment which enhances heat removal from the embankment and underlying ground to preserve the permafrost layer throughout the year.

Abstract: The  telephone  line  coupler  circuit  has  a single transmit opto-coupler whose output includes a DC bias component connected to a gate of a line seize switch for connecting a DC line seize load across the ring and tip contacts of the telephone line.  The line seize switch is saturated by the transmit opto-coupler bias output and the AC component of the transmit opto-coupler output is sent over the telephone lines.  The receive  opto-coupler  is  used  both  for  receiving communications  signal  and  for  detecting  the  ring signal.  The band pass filter connected to the output of the receive opto-coupler may be switched to pass a ring  signal  frequency  band  or  a  communications frequency band.  The circuit operates using two opto-coupler devices while conventional  circuits  require for opto-coupler devices.

IPC: H04B17/00
Filed: 1994-09-14
Granted: 2002-11-26
Abstract: Disclosed herein are methods and apparatus for detecting the presence of a CDPD carrier in a channel of a cellular system (although the invention is broadly applicable to detecting a specific kind of carrier associated with an "overlay" system, wherein an "overlay" system is one that shares the frequency allocation of another system on a non-cooperating basis). This specification describes a spectral estimation technique for detection of a CDPD carrier. In addition, this specification describes an MMSE (minimum mean-squared error) method that improves on the spectral estimation method.
Patent CA-2173841-C (CA)
Title: Ultrasonic spectral contrast imaging
Inventor: ARDITI MARCEL
IPC: A61K49/00
Filed: 1995-09-21
Granted: 2007-01-23
Abstract: This invention is applicable to the electronic circuits found in echographic imaging instruments, such as those used for medical diagnosis. Its implementation requires the injection of specific contrast agents in the body, or more generally in the region to be imaged. The underlying principle of the new imaging proposed is based on use of frequency dependent bahaviour of the ultrasound contrast agents containing microbubbles. In essence, these imaging principles exploit certain physical "signatures" of the contrast agent responses, allowing increased contrast with respect to tissue background. This contrast enhancement is much larger than what is determined from direct echo amplitude monitoring.

Abstract: Method and apparatus for modifying an odometer reading in a vehicle navigation system to compensate for odometer errors.  A first distance measurement is obtained from the odometer, and a second distance measurement is obtained from at least one other sensor.  The difference between the first and second distance measurements is determined and an adjustment amount is generated in response thereto.  A modification factor is then adjusted by the adjustment amount, the modification factor being for modifying the odometer reading.  The odometer reading is then modified with the modification factor.  A method and apparatus for selecting a pulse rate setting in a vehicle navigation system to correspond to a pulse rate associated with the odometer are also described.  A first distance measurement is obtained from the odometer and a second distance measurement is obtained from at least one other sensor.  The difference between the first and second distance measurements is then determined. The pulse rate setting is changed to correspond to the odometer pulse rate if the difference is greater than a threshold level, and is left unchanged if the difference is less than the threshold level.

Title: Isdn d channel restoration without loss of signaling or packet data
Inventor: BALES BRUCE M
IPC: H04L69/40
Filed: 1997-04-17
Granted: 2000-02-15
Abstract: A communication switching system has a plurality of switch nodes with each of the switch nodes responsive to a failure of the primary signaling channel that is providing the common signaling channel in a facility access service (FAS) group to immediately switch to the secondary signaling channel of the FAS group. This switching occurs quickly so that no calls are dropped within the FAS group. Any logical links being communicated on the primary signaling channel are transferred to the secondary signaling channel with no data packets being irreplaceable lost. A first physical object is established to control a physical protocol on the primary signaling channel, and a second physical object is established to control the physical protocol on the secondary signaling channel. Further, a single software object is established to always control the first layer of software protocol on the common signaling channel whether that is the primary signaling channel or secondary signaling channel. When failure of the primary signaling channel is detected, information for the common signaling channel is routed from the second physical object to the software object, thereby preserving the common signaling channel.
