Patent CA-2132557-A1 (CA)
Inventor: RANGACHAR HEMMIGE V
IPC: H04Q3/00
Filed: 1994-09-21
Abstract: Access of a user to a resource, such as a telecommunications network, includes storing, in a first call data base, a first set of attributes concerning an ongoing call from a caller.  A second call data base stores a second set of attributes concerning the history of prior calls made by the caller. A rules data base stores rules concerning attributes for determining whether to disconnect the call, block future calls, or take other action.  A determination is made whether data in at least one of the call data bases matches the rules in the rules data base. The call is then disconnected, the next call blocked, or other action is taken, in response to a match between data the call data bases and data in the rules data base.  Preferably, the second call data base is updated in response to matches with the rules data base.

Patent CA-2134541-A1 (CA)
Inventor: HASLAM GARY M
IPC: G01J1/46
Filed: 1994-10-27
Abstract: A passive  infrared detection  and conversion  circuit includes a pyrosensor, a current amplifier, a capacitor, and a signal processor circuit.  The signal processor is operable to charge the capacitor to a first voltage level and to measure a capacitor discharge time, the time required for the capacitor to discharge from the first voltage level to a second voltage level.  The signal processor is further operable to generate an electrical control signal responsive to a variation in the capacitor discharge time which corresponds to a significant motion event.      In a preferred embodiment, when the pyrosensor is exposed to infrared motion, it generates a transient current, and the capacitor discharge time corresponds to the transient current. The signal processor circuit includes logic operable to compare the capacitor discharge time with a long-term average capacitor discharge time.  The signal processor circuit generates the electrical control signal only when the capacitor discharge time deviates from the long-term average capacitor discharge time by exceeding a predetermined threshold margin and/or satisfying other timing and/or pulse sequence patterns.  The logic of the signal processor circuit may be further operable to calculate  and update  the  long-term  average  capacitor discharge time based on the capacitor discharge time such that the logic filters out unwanted background signals and component tolerance variations, thereby creating a dynamic threshold system for detecting significant motion.

Title: Subcarrier communication system
Inventor: CHADWICK DAVID J
IPC: H04H20/34
Filed: 1995-02-01
Abstract: A communication system (100) is provided for transmitting data to mobile receivers utilizing a subcarrier within a commercial FM channel of a radio station (55). The data transmitted is first encoded in encoder (112), utilizing a forward error correction code.      The sequence of the encoded data is altered in interleaver (116), subdivided into a plurality of subframes, in framing and synchronization circuit (120), which also adds channel state bits to each subframe. The framed data is modulated onto the subcarrier in the differential quadrature phased shift keying modulator (130), the output of which is coupled to the FM modulator (52) of radio station transmitter (50). The transmitted radio frequency signals may be received by a vehicle antenna (12) for coupling to the vehicle's FM receiver (80). The modulated subcarrier is recovered from the FM demodulator (84) of the receiver (80), the modulated subcarrier being demodulated to recover the encoded digital data therefrom.        The channel state bits included with the data are extracted from the digital data and utilized to form a data reliability factor for each bit of the encoded data.      The data reliability factors thus obtained are associated with each bit of the data in a deinterleaver (360).      Deinterleaver (360) provides each data bit in proper sequence, with its associated data reliability factor to a decoder (370). The decoded digital data is provided to a vehicle traffic computer (90) for processing and presentation of traffic information to a user on a display (92).

Title: System and method for interfacing to a transaction processing system
Inventor: GILBERT PETER W
IPC: G06F9/46
Filed: 1993-10-14
Abstract: A system and method for interfacing external processes to a transaction processing system. An interface system is provided that accepts input messages from external processes wherein in the input messages are to be processed by a transaction process-ing system. The interface system logs received messages and notifies the transaction processing system that a message has been received for processing. The interface system sends a confirmation to the external process indicating that the message has been received. The interface system periodically examines the status of each message as it is being processed by the transaction pro-cessing system. Output status messages indicative of such status are created, stored, and sent to an external destination for infor-mational purposes. Outbound data messages are created, stored and sent to an external application. The interface system is event driven, but includes a monitor subsystem to time the start-up of certain processes at periodic intervals.

Patent CA-2150109-A1 (CA)
Inventor: HUNT ALAN K
IPC: H04M3/38
Filed: 1993-11-24
Abstract: A method for enabling a caller to obtain access to one or more services via a telephone network by speaking a password is described. The method begins by establishing at least one predetermined threshold value for a speaker verification signal. For each spoken character of the password, the method generates a set of parameters using a voice verification feature transformation. After entry and recognition of the password, the sets of parameters are used to generate a speaker verification signal for the password. Upon the occurrence of a predetermined call condition, the predetermined threshold value is adjusted to increase the level of security in the verification algorithm. If the signal verification signal for the password has a predetermined relationship with respect to the adjusted threshold value, the caller's identity is accepted. If not, the caller may be asked to answer certain personal questions before his or her identity is accepted.

The corner connector (3) comprises two angular pieces (4) at least two wedging pieces (5) at least two bolts (6) and at least two clamping pieces (7). The angular pieces (4) have on each flange a wedging surface (22) that press against the nose (14) of the struts (12) and a wedging surface (28) on the side opposite the flange. The wedging piece (5) is drawn by bolt (6) over the wedging surface (28) between the flanges (20) causing the flanges (20) to be tensed against the section. The clamping pieces (7) engage on the projections (13) on the struts (12). The wedging pieces (5) tensed against the clamping pieces (7) do not cause the flanges (11) to be spread apart. This arrangement results in a joint exhibiting high bend strength and high tensile strength in particular by means of friction.

Title: Co-deposition of palladium during oxide film growth in high-temperature water to mitigate stress corrosion cracking
Inventor: ANDRESEN PETER LOUIS
IPC: B01J37/03
Filed: 1995-09-28
Abstract: A method for improving the performance and longevity of coatings of metal deposited from aqueous solutions of inorganic, organic or organometallic metal compounds. The method involves co-deposition of noble metal or corrosion-inhibiting non-noble metal during growth of oxide film on a component made of alloy, e.g., stainless steels and nickel-based alloys. The result is a metal-doped oxide film having a relatively longer life in the reactor operating environment. In particular, incorporation of palladium into the film provides greatly increased catalytic life as compared to palladium coatings which lie on the oxide surface.
