Title: Method for providing an open interface to automatic recall service
Inventor: MALIK DALE W
IPC: H04M3/424
Filed: 1998-06-30
Abstract: A method for providing an open interface, or access to, information that is stored in a called party switch in relation to an automatic recall telecommunications service. Automatic recall service allows a customer to dial a special feature code and receive an enunciation of the directory number of the last incoming caller. Typically, automatic recall-related information is stored in the called party switch and is not accessible to external network elements that may provide enhanced services with this information. This automatic recall-related information may include information such as the directory number of the last incoming caller, the time stamp of the last incoming call, and/or the privacy indicator of the last incoming call. The method includes placing the automatic recall-related information into at least one field of a telecommunications message, such as an ISUP message. The message is routed from the called party switch to the terminating network element that is to provide an enhanced service. The terminating network element may then retrieve the automatic recall-related information from the fields of the message. The terminating network element may then use the automatic recall-related information to provide enhanced services.

Title: Repositioning of articles between different positions within an intermittently accessible space
Inventor: BROWN PAUL PHILIP
IPC: B29C45/10
Filed: 1998-08-14
Abstract: Articles, such as components of an injection-molded multi-component product, are repositioned within a space, such as the space between mold parts, that is accessible for repositioning only during a series of periods, such as open-mold periods, that are separated by intervals of less accessibility for repositioning, such as closed-mold intervals by (a) moving a first article, such as a first component of a first multi-component product, from a first position within the space to outside of the space during a first such period; and (b) moving a second identical article, such as a first component of a secondmulti-component product, from outside of the space to a second position within the space during the first such period. Both the movement of the first article and the movement of the second article are by means of a common vehicle, such as a common robot arm. In another aspect, an article is repositioned by (a) moving the article from a first position within the space to outside of the space during a first such period; and (b) during a second such period after an interval of less accessibility that is subsequent to the first period, moving the article from outside of the space to a second position within the space. For injection molding with a stack mold, an article is repositioned from a first mold-cavity in a first space in a first portion of the stack mold to a second mold-cavity position in a second space in a second portion of the stack mold by (a) moving the article from the first position to outside of the first and second spaces during a period when the first space is accessible and the second space is inaccessible; and (b) moving the article from outside of the spaces to the second position when the second space is accessible and the first space is inaccessible.

Patent CA-2248145-A1 (CA)
Inventor: KHAN SAIFULLAH
IPC: G01B15/02
Filed: 1997-03-03
Abstract: This invention is directed toward the measure of the thickness of material using nuclear techniques. More particularly, the invention is directed toward apparatus and methods for measuring the thickness of pipe wall, from the outside of the pipe (70), using an annular detector (50), concentric conical detector collimation (26), and backscatter gamma radiation. A source of gamma radiation (14), preferably at energy 279 keV from mercury-203, is collimated into a pencil beam and impinged perpendicularly upon the outside of the pipe wall to be measured. Compton backscatter radiation from the pipe wall is then measured with an annular, concentric photon detector which preferably comprises a scintillation crystal, such as sodium iodide, optically coupled to a single photomultiplier tube. Pipe thickness is determined from detector response using a predetermined relationship obtained during system calibration. Conical, concentric detector collimation is used to obtain accurate and precise measurements when the pipe is filled with liquid.

Patent CA-2255797-A1 (CA)
Title: Tonometer
Inventor: DAYMAN JEFFREY GEORGE
IPC: A61B3/16
Filed: 1997-05-23
Abstract: A tonometer (10), for determining intraocular pressure, has a body, which can be a transparent substantially tubular body (12). A plunger (28) is located within the body and a coil spring (36) acts between the body and the plunger. A marker (24) member is frictionally retained within the body and is displaced relative to an external scale (20) on the body. In use, the tonometer is brought up against the eyelid (50) of a closed eye and the body displaced relative to the head of the plunger until the pressure is sufficient to create a pressure phosphene. The device is then removed and the displacement of the marker member indicative of the applied pressure is read. This reading corresponds to the intraocular pressure. The device may include a return member (49) for returning the marker member to a zero or rest position.

Patent CA-2260002-A1 (CA)
Inventor: EASTLAKE DONALD EGGLESTON III
IPC: G06Q20/12
Filed: 1997-06-06
Abstract: A system for determining approval of a multi-currency transaction between a merchant and a customer using currency exchange. The customer and merchant obligations relating to such a transaction can be fixed at the time of the transaction. Risks to these parties heretofore associated with currency exchange is minimized. The parties to a multi-currency transaction authorize an approving entity to settle the transaction. Authorization is granted by virtue of the customer and merchant setting up accounts knowing that transactions will be submitted and processed by the entity holding the accounts. The parties transmit data representing the transaction to the approving entity. This data includes an amount in a first currency that a customer is willing to pay for a product and a price in a different second currency which a merchant is willing to accept for the product. Using predetermined criteria, the approving entity approves the transaction. Once the transaction is approved, the approving entity may settle the transaction at its discretion thereby bearing the risk associated with currency exchange.  The parties, however, incur no risk. The customer will pay the amount in the first currency and the merchant will receive the price in the second currency.  These are values known and agreed to by the parties at the time of the transaction.
