Patent CA-2143846-A1 (CA)
Inventor: FISHER MICHAEL A
IPC: G02F3/02
Filed: 1993-09-08
Abstract: A non-linear semiconductor optical device (3) comprises an active waveguide with a multiple quantum well construction in the active region. The device (3) is supplied with a drive current at the material transparency current with respect to an optical pump. An optical non-linearity appears with respect to input radiation having a wavelength below that of the bandgap equivalent wavelength of the active region (.lambda.<.lambda.g), the effect being achieved at relatively low optical input powers. The non-linearity is fast enough that a switching device incorporating the invention, in use as a demultiplexer, has potential to be used at bit rates approaching the Tbit/s range. In a demultiplexer embodiment, the non-linearity may be exploited in a directional coupler (40), an optical pump being used intermittently to control cross-over of an incoming TDM data signal so as to "pick off" a selected channel. Other applications include optical logic devices.
Patent CA-2144114-A1 (CA)
Title: Method and apparatus for electrically and mechanically interconnecting electrical components
Inventor: HILL DOUGLAS J
IPC: H05K5/02
Filed: 1995-03-07
Abstract: A portable electronic device having a stationary housing enclosing a first electric circuit and a pivotable housing enclosing a second electric circuit, uses a mechanical and electrical interconnection assembly for interconnecting the two housings and circuits. The mechanical assembly includes a pivot and friction assembly that pivotally couples the stationary and pivotal housings together, and allows the pivotable housing to be held at a variety of angular orientations with respect to the stationary housing. The electrical assembly includes an electrical connector of a flexible web type that pivotally and electrically connects the first and second electric circuits together. Rather than pivoting at the pivot point or axis, the electrical connector pivots about or along a relatively great distance compared to the pivot axis, thereby greatly reducing the possibility of the electrical conductor breaking at the pivot.

Title: High precision on-line dynamic signature verification system
Inventor: LIVSHITZ ALEXANDER
IPC: G06K9/66
Filed: 1993-03-04
Abstract: A method for on-line handwritten data verification based on the comparison of the dynamics of sample (31 or 32) and reference data (21 or 22) by implementation of correlation function analysis. Reference dynamic data concerning scriber (11) movement during data formation is recorded and converted to digital form (13). Prior to evaluation to-be-verified data, both the reference and to-be-verified data dynamic digital signals are pre-processed to eliminate time distortions. A "sliding window" mechanism is used to establish the mapping between phase coincident regions of the reference and of the to-be-verified signals.    Then multi-dimensional cross-correlation function analysis is applied to the pair of indivisible stationary signals. The resulting measures of similarity an then compared with thresholds that have beta selected to determine acceptance or rejection of the to-be-verified signals. The method and the apparatus can be applied to data authentication in a wide variety of applications like security for physical mess, for credit card authentication, electronic voting, and the like.

Title: Load interrupting device for live front padmounted switchgear
Inventor: HARR DEBORAH L
IPC: H01H33/06
Filed: 1995-09-25
Abstract: A load interrupter device is provided for live front padmounted high voltage switchgear unit wherein circuit interruption  is  independent of the speed at which a lineman opens the switch of the switchgear.  The inter-rupter includes an insulating body having a fixed terminal and a moveable terminal spaced therefrom which forms a part of manually operable switch structure.

A pair of moveable conductive members are also provided in the body, with one of the conductive members normally engaging a contact electrically connected to the first terminal, while the second member is joined to the second terminal for move-ment therewith.  Spring mechanism interconnecting the two members and in association with a detent causes the first conductive member to be retained in engagement with its associated contact until after the conductive element clears the first terminal whereupon the first conducting member is then acceleratedly moved out of engagement with the first contact to break the circuit and create an arc which is rapidly suppressed by material making up a part of the interrupter body.
