Patent CA-2146978-A1 (CA)
Title: Erasable Marking Medium Composition
Inventor: SMITH MARK
IPC: C09D11/16
Filed: 1993-10-25
Abstract: An erasable writing medium composition suitable for use in porous tip pens and roller-ball pens is provided. The erasable writing medium comprises an emulsion having a continuous water phase and discontinuous phase that is comprised of a rubber. Pigment particles are exclusively associated with the discontinuous phase. Although the emulsion composition has a very low viscosity, very low surface tension, and very small rubber particle size, it is stable before use. Upon application of the composition to the highly ionic surface of standard stationary-type paper, the emulsion becomes unstable and the rubber agglomerates, and does not penetrate the paper. Upon drying, the pigment remains within the rubber phase thereby preventing the pigment from being absorbed by the writing surface. The rubber phase therefore forms a pigmented layer on the writing surface. The layer can be removed by erasure so that no pigment remains on the writing surface.

Patent CA-2148961-A1 (CA)
Title: Linear Alternating Current Interface for Electronic Meters
Inventor: MAK SIOE T
IPC: G01R15/18
Filed: 1995-05-09
Abstract: An interface circuit (10) for use with electronic metering equipment (E) to provide a linear output response to an AC or analog input. An air core transformer (12) has a first coil or winding (12a) connected to a load (L). An AC current ILOAD is produced by the load and is coupled to a secondary coil or winding (12b) of the transformer.  The transformer has an air core rather than a ferromagnetic core so to have no saturable core. Because no load is drawn by transformer coil, the voltage across a terminal of the coil equals the EMF induced in the coil The EMF, in turn, equals the mutual inductance of the coils multiplied by the rate of change of magnetic flux linkages over time. The output from the transformer is applied as an input to an operational-amplifier (16) which has a high input impedance. Further, the amplifier is a low drift amplifier which performs a linear amplification of the input signal provided thereto. In certain embodiments, a pair of similar amplifiers are used and the secondary winding of the transformer is a tapped winding so to accommodate both a low range and a separate high range of inputs. The output from the operational amplifier is supplied to an analog-to-digital converter (18) so a digital output is supplied to the metering equipment. If the tapped coil, dual amplifier arrangement is used, the resolution requirements of the converter are lower than if the single amplifier circuit configuration is used. Use of the interface circuit eliminates the DC component of the sensed voltage and provides a linear response for the metered AC input to the measuring equipment.

Title: Method and apparatus for coating fibers
Inventor: ABBOTT JOHN STEELE III
IPC: B05C3/12
Filed: 1996-02-05
Abstract: In the process of drawing optical fibers, a protective plastic coating is applied to the fiber by applying a curable liquid coating material thereto and the subsequently curing the liquid coating to a protective plastic layer.

Title: Method and apparatus for authentication in a communication system
Inventor: FINKELSTEIN LOUIS DAVID
IPC: H04M3/38
Filed: 1995-06-07
Abstract: A method and apparatus for authenticating a roaming subscriber. In a preferred embodiment, a subscriber receives a challenge that is in a format of a local authentication protocol, and determines whether the local authentication protocol is the subscriber's home system authentication protocol. If it is not, the subscriber converts the challenge into a format (e.g., bit length) compatible with its home system authentication protocol, and processes the converted challenge with the subscriber's secret key and authentication algorithm into an authentication response. The authentication response is converted to be compatible with the local authentication protocol, and transmitted to a local system communication unit. The challenge and response is then forwarded to the subscriber's home system for similar conversion and processing, and subscriber's response is compared against a home system generated response.

IPC: G06F19/00
Filed: 1994-11-22
Abstract: A Radiology Healthcare Network provides high quality, timely medical interpretations of radiological images on a national (e.g,, across the U.S.) and regional basis.  The images can include images created by con-ventional  x-ray technology, computed radiography, mag-netic  resonance imaging (MRI), computed tomography (CT), ultrasound imaging, nuclear medicine, and mam-mography equipment. The invention includes the  ac-quisition of these images from health care facilities, the conversion of these images to digital format, the rout-ing of these converted images, the interpretation of these routed images, and the routing of the interpretations back to the originating facility. The images are routed (e.g., on a variety of high-speed digital and analog  telecom-munication networks) to the  appropriate interpretation resource by an administrative site on the  Network based on one or more requirements associated  with the radi-ological study.   The interpretation can be performed on high-resolution workstations and/or on films produced by film printers.  The invention can include quality con-trol measures which assure high image and interpretation quality.  The control and tracking of images by the ad-ministrative site results in the production of a complete, signed interpretive report in a timely manner.
