Patent CA-2085498-A1 (CA)
Inventor: PRESBY HERMAN M
IPC: G02B6/02
Filed: 1992-12-16
Abstract: An asymmetric hyperbolic microlens on the end of a single-mode optical fiber enhances the fiber's coupling to elliptical laser beams. The lenses, with controlled eccentricity ratios, are made by micromachining the end of the fiber with a pulsed CO2 laser as the fiber is directed, preferably by computer control, about the focused laser beam. Coupling effiencies of 90 percent (-0.75 dB) have been realized with single transverse mode transverse mode lasers at a wavelength of 0.98 µm having an approximately 3 to 1 beam ellipticity. With multimode lasers at 1,48 µm having similar elliptical beams, the asymmetric lenses demonstrate an almost 2 dB increase in coupling efficiency over symmetric hyperbolic microlenses. Such lasers are useful to pump erbium-doped fiber amplifiers.  About 120 mw was coupled from such a laser into single-mode fiber.
Patent CA-2088321-A1 (CA)
Title: Multiple cross-check document verification system
Inventor: SCHATZ VERNON L
IPC: G07F7/12
Filed: 1993-01-28
Abstract: ABSTRACT OF THE DISCLOSURE      A check verification and transaction method in which a payee of a check is identified by a personal identification number PIN.  A data encryption algorithm is applied to the PIN i to produce a first number that is recorded on the check. Afterward, a PIN is ascertained from a bearer on the check, and the same data encryption algorithm is applied to the PIN as ascertained from the bearer to produce a second number. The first and second numbers are compared, and an indication is produced if the first and second numbers do not coincide. The data encryption algorithm, instead of being applied to the PIN alone, may be applied to the PIN and to a further number together to produce the first number, the further number also being recorded on the check.  Advantageously, the further number may be a check sequence number or an amount of the check.  The method validates the authenticity of the check being presented for payment, the eligibility of the individual presenting the check, and the validity of the relationship between the two.  The authenticity of the check being presented for payment is validated by means of a "check derivation" printed on the front of the check at the time of issue and computed from the PIN of the named payee and a secondary key, also printed out on the front of the check. The eligibility of the individual presenting the check is validated by means of eligibility information to be read by the person cashing the check and stored on a card, preferably an integrated circuit card, or "smart card".  The validity of the relationship between the check being presented for payment and the individual presenting the check is also verified by means of a check derivation, since the individual presenting the check must be capable of entering the PIN of the named payee of the check in order for the check derivation to be correctly and independently produced by a transaction terminal at the point of use.
Patent CA-2090395-A1 (CA)
Inventor: YOKOI SHIN
IPC: A62C37/44
Filed: 1993-02-25
Abstract: An indoor fire hydrant apparatus includes a fire hose having electrical conductors extending along its length and connected to a switch mounted near the nozzle end of the hose.  Closure of the switch causes energization of a solenoid-actuated valve which is connected between a source of water under pressure and the hose.          Closure of the switch also causes energization of a pump to build up the water pressure.  A single person may pull the hose from a rack, extend it toward a fire, and actuate the switch thereby causing water under pressure to be dispersed through the nozzle.          The electrical conductors may be embedded in a wall of the fire hose or mounted on an exterior surface of the hose.  The hose may be of the folding type or the type which maintains its generally circular shape.
