Patent CA-2183222-A1 (CA)
Title: Signal Processing Unit for a Trolley Pole Switch Controller
Inventor: LAUNIER FRANCIS A
IPC: B60M1/14
Filed: 1996-08-13
Abstract: A signal processing unit for a controller of a trolley pole switch is disclosed.  The trolley pole switch switches the path of travel that an energy collector takes through the switch at a  junction of catenaries  at which a turn catenary and a straight catenary diverge from the straight catenary. The signal processing unit includes an input stage, a detection stage, turn and straight signal demodulation stages and an output stage.  The input stage conditions modulated signals, each of which indicating a request to switch the path of travel through  the  trolley  pole  switch  to  the  desired  catenary diverging  therefrom.    The  detection  stage  generates  a validation signal if the conditioned modulated signal falls within a predetermined band.  If the turn demodulation stage receives a conditioned modulated turn signal from the input stage  and the validation  signal  from the detection  stage simultaneously,  it generates a low logic  signal.   If the straight demodulation stage receives a conditioned modulated straight signal from the input stage and the validation signal from the detection stage simultaneously, it generates a low logic signal.  If a low logic signal is received from the turn demodulation stage, the output stage energizes a turn relay thereby supplying power to a turn solenoid for switching the path of travel to the turn catenary.  If a low logic signal is received from the straight demodulation stage, the output stage energizes  a  straight  relay  thereby  supplying  power  to  a straight solenoid for switching the path of travel to the straight catenary.

Title: System and method for maintaining personal communications information ina mobile communications system
Inventor: FOLADARE MARK JEFFREY
IPC: H04W4/029
Filed: 1996-10-08
Abstract: The invention is an apparatus and method for updating a communications network from one or more user communications devices. The invention uses the electronic scheduling or other time-based features within a communications device to control and/or initiate transmission of information between the communications device and the communications network. Information from one or more communications devices is updated to the communications network in response to time-based components in the information entries corresponding to a timing device associated with the respective communications device. Also, once the network has received this updated information, comparisons of related information entries are initiated to detect discrepancies therebetween. In this manner, user submitted time and geographic location information is compared with similar information automatically retrieved by the communications network using conventional and future network communications technology. Any detected discrepancies are used to initiate appropriate notification to the user and/or retrieve updated information, or to default to existing message delivery systems.
Patent CA-2188175-A1 (CA)
Inventor: JANI WILLIAM
IPC: E21B23/00
Filed: 1996-10-17
Abstract: A tubing tightener which is readily adaptable to either clockwise or anti-clockwise rotational setting operation and which uses a series of drag slips having integral drag and slip surface regions. The drag surface regions are substantially smooth and are advanced into contact with a wellbore with the slip surface regions retracted, when the tightener is in its unlocked orientation. The slip surface regions are serrated to provide a positive engagement with the wellbore and are advanced into engagement with the wellbore with the drag surface regions retracted, when the tightener is in its locked orientation. The drag slips are caused to rock about a point of contact between the drag slip surfaces and the wellbore, located intermediate the drag and slip surface regions, in order to advance the appropriate surface region of each drag slip into engagement with the wellbore. The invention provides for a compact, lightweight construction with improved reliability and increased bypass around the tightener.

Title: Method for phasing electronic labels and reading station and electronic label used in said method
Inventor: RAIMBAULT PIERRE
IPC: G06K7/00
Filed: 1996-11-29
Abstract: The remote interrogation system has multiple tags responding simultaneously to a single query from the interrogation post. The tags are initially synchronised by a single command from the interrogation post. The synchronisation for the tags involves counting of the cycles of an alternating signal and determining the polarity of a particular half-cycle. The tag then responds on that particular half-cycle. The tags respond at a transmission frequency that is a sub-multiple of the transmission frequency from the interrogation post. The interrogation signal is emitted in sequence in different directions.

Patent CA-2198375-A1 (CA)
Title: An antenna
Inventor: LEISTEN OLIVER PAUL
IPC: H01Q1/36
Filed: 1995-08-21
Abstract: An antenna for use at UHF and upwards has a cylindrical ceramic core (12) with a relative dielectric constant of at least 5. A three-dimensienal radiating element structure, consisting of helical antenna elements (10A - 10D) on the cylindrical surface of the core (12) and connecting radial elements (10AR - 10AD) on a distal end face (12D) of the core, is formed by conductor tracks plated directly on the core surfaces. At the distal end face the elements are connected to an axially located feed structure in a plated axial passage (14) of the core (12). The antenna elements are connected together by a plated sleeve (20) covering a proximal part of the core (12) which, in conjunction with the feeder structure, forms an integral balun for matching to an unbalanced feeder.     Since the ceramic core fills the major part of the interior volume defined by the radiating element structure, the antenna is very much smaller than an air-cored antenna. It is also mechanically robust and electrically stable.
