Patent CA-2196332-A1 (CA)
Inventor: BIGO SEBASTIEN
IPC: H04B10/2569
Filed: 1997-01-29
Abstract: The non-linear optical mirror (NOLM) is formed in a loop of optical fibre, with its operation being independent of the polarisation of the signals offered on the signal and control inputs (wavelengths lambda-s and lambda-c respectively). The loop is composed of four sections (T1, T2, T3, T4) of fibre maintaining polarisation and of equivalent optical length. These sections are linked by three splices (E1, E2, E3) at three locations. At the first and third splices, the neutral propagation axes of the fibre are turned by 90 degrees. At the second splice a mode converter is inserted in the loop. This comprises an optical demultiplexer and multiplexer, as well as two optical channels connecting them. The demultiplexer divides the two signals (lambda-s and lambda-c) into the two channels. The channel carrying the control signal effects a 90 degree rotation. On the other channel there is no rotation. The multiplexer then recombines the two signals.

In order to repair a crack, a length of the material is selected and has a diameter corresponding to the crack width.The material is packed into and near the top of the crack, and is then melted topermanently seal and repair the crack.
Patent CA-2203917-A1 (CA)
Inventor: ASHLEY JAMES P
IPC: H04Q7/20
Filed: 1996-09-04
Abstract: A noise suppression system (109) implemented in communication system (700) provides an improved update decision during instances of sudden increase in background noise level. The noise suppression system (109), inter alia, generates an update by continually monitoring the deviation of spectral energy and forcing an update based on a predetermined threshold criterion. The spectral energy deviation is determined by utilizing an element which has the past values of the power spectral components exponentially weighted. The exponential weighting is a function of the current input energy, which means the higher the input signal energy, the longer the exponential window. Conversely, the lower the signal energy, the shorter the exponential window.  The noise suppression system (109) also inhibits a forced update during periods of continuous, non-stationary input signals (such as "music-on-hold").

Title: Scanning circuit for pressure responsive array
Inventor: OREPER BORIS
IPC: G01L15/00
Filed: 1995-11-03
Abstract: A scanning circuit for an array of pressure responsive sensor points which permits the sensitivity of the circuit to be controlled. In particular, the sensitivity of the circuit may be controlled by controlling a test and/or reference voltage used with the circuit and different sensitivity or resolutions may be provided for different areas of the array.  The circuit also provides enhanced interelectrode isolation, permitting a single test voltage to be utilized to scan all sensor points on a given input electrode and further reduces the time required to scan the array by reducing trace capacitance discharge time and by inhibiting processing for sensor ports which are not of interest. The accuracy of pressures being sensed is also enhanced by adjusting the rest voltage to compensate for load variations.
