Patent CA-2159845-A1 (CA)
Title: Enabling technique for quickly establishing high speed pstn connections in telecommuting applications
Inventor: HANSON BRUCE LOWELL
IPC: H04M11/06
Filed: 1995-10-04
Abstract: A data communications equipment, e.g., a modem, uses a telephone number of a remote endpoint to retrieve an associated set of stored configuration parameters. These stored configuration parameters allow the modem to quickly initialize itself and thereby significantly reduce the training interval with the remote modem. In addition, the use of the telephone number of the remote endpoint allows quick identification of modulation format, e.g., that a fax call is being established.

Title: Non-handed, concealed-screw lock mounting mechanism
Inventor: GALINDO JAIME
IPC: E05B15/02
Filed: 1994-04-25
Abstract: A non-handed  door lock capable of installation on doors of varying thicknesses and having concealed screws (160) on both inside and outside handle assemblies (10) has inner and outer chassis (50, 150) which may be reversed depending upon the handing of the door.

Title: Mass spectrometry method with two applied trapping fields having same spatial form
Inventor: KELLEY PAUL E
IPC: H01J49/42
Filed: 1994-05-25
Abstract: An improved field comprising two quadrupole trapping fields is established in a region (16) defined by the ring (11) and end (12, 13) electrodes of a three-dimensional quadrupole ion trap, and the amplitude of an RF (and/or DC) component (and/or the frequency of the RF component) of one or both trapping fields is changed to sequentially excite trapped ions. Alternatively, a trapping field capable of storing ions having mass-to-charge ratio within a selected range is established, a supplemental field is superimposed with the trapping field to eject unwanted ions having mass-to-charge ratio within a second selected range, the supplemental field having frequency components in a frequency range except for a notch frequency band within the range, and an improved field is then established by superimposing the trapping field with a second trapping field of substantially identical spatial form.

Patent CA-2181691-A1 (CA)
Title: Method and Apparatus for Scrambling and Descrambling of Audio Signals
Inventor: QUAN RONALD
IPC: H04B15/00
Filed: 1994-10-18
Abstract: Audio signals are descrambled by double sideband modulating the scrambled audio signal with a modulation carrier having a carrier frequency slightly above the highest audio signal present in the scrambled studio. This produces a double sideband signal that is passed through a low pass filter which in turn is modulated by a second carrier frequency lower than the first carrier signal by an amount equal to the offset spectrum of the original scrambled signal. The first low pass filter nulls out any residual carrier from the first modulator that results from the intermodulation of the two modulation frequencies that would be audible at its descrambler output. The modulators used are low noise switch type modulators that improve the signal to noise ratio in the descrambled signal over the previously used linear modulators. The use of switch type modulators provides a lower cost device with improved performance. A companion scrambling device uses similar technique to provide improved performance at a lower cost.
Patent CA-2181848-A1 (CA)
Inventor: BARR FREDERICK JAMES
IPC: G01V1/36
Filed: 1996-07-23
Abstract: In the presence of an anisotropic near-surface earth layer, orthogonally oriented microspreads are provided from which shear-wave velocity vectors Vse and Vsie may be determined. The respective velocities are calculated from measurements of the direct path first arrivals and of the velocity of the boundary waves propagating along the upper boundary of the near surface layer. The ratio of the near-surface shear-wave velocity vectors is used to scale the static time corrections attributable to seismic data received by shear wave sensors whose axes of responsivity coincide with the orientation of the microspreads.

Title: Method of operating at least one fluorescent lamp with electronic ballast, and ballast therefor
Inventor: KRUMMEL PETER
IPC: H05B41/282
Filed: 1995-07-03
Abstract: The invention concerns a method of operating at least one fluorescent lamp (FL) by means of electronic ballast and the ballast itself. A rectifier bridge (GL) at a.c. supply voltage (L, N), a connected high-value regulator (L1, D1, V1), a half-bridge circuit (V2, V3) and a control and regulating circuit (IC) are provided for continuously monitoring the lamp current with a regulated control circuit (CCO, SEL, HSD, LSD) for the power transistors (V2, V3) which maintains the bulb current constant during normal operation. As a master control system, a time-value emitting device (PST, IT, CT), which is activated in a specific manner whenever the lamp is activated or a fault is detected, generates a time base for a monitoring circuit (MON) which evaluates the lamp current at any particular moment at predetermined reference levels (Mp, Mi and Mo) which differ in individual time sections (.DELTA.pt, .DELTA.it, .DELTA.st, .DELTA.ot) and which, via the regulated control circuit (CCO, IST, SEL, HSD, LSD), controls the lamp current as a function of time if the lamp starts normally and triggers automatic switching-off of the electronic ballast in the event of a fault.
