Patent CA-2200112-A1 (CA)
Title: Mechanical/electrical displacement transducer
Inventor: JACOBSEN STEPHEN C
IPC: G08C21/00
Filed: 1990-10-03
Abstract: Displacement measuring apparatus for measuring the displacement and movement of an object includes a sensor having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the area of the operative surface covered by an electrical/magnetic field producing member.  The apparatus also includes an elongate, flexible band capable of producing an electric/magnetic field, where the band is attached at one end to the sensor to roll over and cover or unroll from over and uncover the operative surface as the object whose displacement is to be measured is moved.  The value of the electrical output signal produced by the circuitry is thus dependent upon the area of the operative surface covered by the band and thus by the position and movement of the object.

Patent CA-2225136-A1 (CA)
Title: Technique for detecting modem devices to enhance computer network security
Inventor: CHESWICK WILLIAM ROBERTS
IPC: H04Q3/58
Filed: 1997-12-18
Abstract: A technique for the identification of unauthorized modems operating within a particular telecommunications environment. A telecommunications switch is adapted to monitor the use of modems on the individual telephone lines emanating from a particular premise. The telecommunications switch detects certain characteristics indicative of modem communications across telephone lines by identifying certain signals used, for example, in standard modem communications. For example, such signals could be those as established by industry data communications standards which specify standard signals, tones, handshaking, or other protocols for initiating, continuing and ending communications between modems. Advantageously, a telecommunications service provider uses their telecommunications equipment to generate, for example, periodic reports which identify those telephone numbers from particular customer premises which exhibit modem communications. Thus, the telecommunications and computer system administrators of the customer can readily determine, directly from the report, which telephone numbers have unauthorized modem connections which pose potential computer network security risks.
Patent CA-2225371-A1 (CA)
Title: Circuit for generating field identification signal and method therefor
Inventor: KIM KI-BUM
IPC: H04N5/08
Filed: 1997-12-19
Abstract: A field identification signal generating circuit for a receiver for receiving a high-definition signal, and a method therefor, are provided.  According to the method, a first correlation value is calculated, between the input high-definition signal and a first reference signal same as a first known signal. A timing control signal, synchronized with a second known signal whose phase is alternately inverted in every field, is output when the first correlation value is greater than or equal to a predetermined value.  A second correlation value is calculated, between the input high-definition signal and a second reference signal same as the second known signal.  Information on the polarity of the second correlation value is output.  A field identification signal is generated on the basis of the polarity information on the second correlation value which is synchronized with the timing control signal.  Therefore, the field identification signal generating circuit can be realized with simple hardware.

Title: Apparatus and method employing a window reset for excessive bit error rate alarm detection and clearing
Inventor: LAU JOSEPH C
IPC: H04L12/26
Filed: 1996-09-27
Abstract: Methods and apparatus for generating and clearing an excessive bit error rate alarm are provided and utilize a window algorithm.    Data blocks of telecommunications signal are monitored in an "idle state" (12). A counter counts the number of incoming blocks in a window such that the block having a code violation count (CV) meeting or exceeding a threshold (CVSET) (14). If the count meets or exceeds its own threshold (x) (26), an alarm state is entered and an alarm is set (30). Otherwise, the system returns to the "idle state" (27). In the alarm state, a clearing counter (CC) counts the number of incomming blocks in the window having a CV of CVCLRR or less (34). If the CC count meets a third threshold value (Y) (45), the alarm is cleared and the system returns to the idle state. Otherwise, the system reverts to the alarm state (47).
