Patent CA-2176478-A1 (CA)
Inventor: LECHLEIDER JOSEPH WILLIAM
IPC: H04L7/033
Filed: 1994-12-07
Abstract: In digital transmission, the combination of transmitted pulse shape and receiver sampling time that maximizes the magnitude of the channel output pulse sample is determined.    The transmitted pulse shape is represented as a linear combination  of orthonormal functions. The coefficients that multiply each of the functions are determined by measuring at the receiver (200) and transmitting   back to the transmitter  (100) the response of the channel to each independently transmitted function at an approximation to the optimal sampling time. A pulse shape is formed using the calculated coefficients and is transmitted to the receiver where the timing of its maximum is determined, which  represents a next approximation to the optimal sampling time. By repeating a plurality of times the processes of transmitting the functions, measuring at the receiver and transmitting back to the transmitter the responses at the approximation to the optimal sampling time, calculating the coefficients, transmitting a pulse, and determining a next approximation to the optimal sampling time from the timing of the maximum in the received pulse, the coefficients and optimal sampling time will converge.

IPC: G06Q10/08
Filed: 1994-12-16
Abstract: In a method for ordering services, like booking hotel rooms, the ordering is performed via a user terminal connected to a central data processing device.  A service request is specified and information of a service is retrieved from a base in the central data processing device. When a given service offer is selected, a connection is automatically established between the user terminal and a service location terminal via the central data processing device, whereupon the desired service can be ordered and the order confirmed.  Further orders can be placed before the connection is broken.  When an order has been made the data base is automatically updated from the service location.  A system is also specified for implementing the method.  In a telemarketing system, a suitable user terminal may be a touch-tone telephone.  The user terminal may also be a dedicated terminal with software for specifying the order.

Title: Digital signatures on a smart card
Inventor: MULLIN RONALD C
IPC: G06Q20/34
Filed: 1997-04-14
Abstract: A digital signature scheme for a "smart" card utilizes a set of prestored signing elements and combines pairs of the elements to produce a new session pair. The combination of the elements is performed partly on the card and partly on the associated transaction device so that the exchange of information between card and device does not disclose the identity of the signing elements. The signing elements are selected in a deterministic but unpredictable manner so that each pair of elements is used once. Further signing pairs are generated by implementing the signing over an anomalous elliptic curve encryption scheme and applying a Frobenius Operator to the normal basis representation of one of the elements.

Patent CA-2220375-A1 (CA)
Inventor: NEWELL MARTIN E
IPC: G06T11/20
Filed: 1997-11-06
Abstract: A computer-implemented method modifies a curve in response to a user action through a graphical user interface in the computer system, with the curve being defined by control points.  Each of the control points is identified in response to user input as a fixed control point, a selected control point, or a free control point.  A displacement of selected points is received, and a free slope control point of the curve is mapped to a point Tp on a line t.  An interpolation curve IC(t) is defined on the line t, and a point Tp is projected to the value of the interpolation curve IC(t) at t equals Tp to find a scale factor. The scale factor is multiplied by the displacement of the selected points to determine the displacement of the free control point.  A computer-implemented graphical user interface method creates a Bezier curve segment on a display in a computer system.  A selection of a first segment end point is received through a graphical user interface in the computer system.  The position of a cursor on the computer display is received as a second segment end point.  The first and second slope points are calculated so that the Bezier segment defined by the first and second segment end points and the first and second slope points approximates an arc.  The calculated Bezier curve segment is displayed on the computer display.
