Title: Method of selecting cable television converter groups
Inventor: BEYERS ROBERT J II
IPC: H04N7/16
Filed: 1994-02-16
Abstract: A method of selecting individual sub-scribers for inclusion in groups by means of certain selection criteria comprises the steps of storing criteria related to terminals of a subscription television system, defining criteria which characterizes a group, logically linking the criteria in a predetermined manner to form a group criteria definition statement, compar-ing the stored terminal criteria with the group criteria definition statement, and assigning an individual or group of terminals to the group when the stored terminal criteria matches the group criteria definition statement.  The selec-tion criteria, for example, may include a range of terminal serial numbers, a range of terminal addresses, the status of the terminal, the service codes for the terminal and subscriber terminal features. The logical operators may include log-ical AND, logical OR, logical NOT, equal to, greater han, less than, parentheticals for joining operators and brackets and separators for ser-vice codes.

Abstract: An inter-network call accounting system for use in a communication network such as the public switched telephone network (1) in Britain allows call records to be sorted according to the network operator to be charged in respect of the calls, prior to being priced and charged. A data analyser (7) incorporating an expert system is provided for call records which cannot be validated. The data analyser (7) can apply default or amended data, or can output invalid data to a suspended process awaiting updated reference information. Unfixable data is output to a sump for management purposes. A pricing and charging engine processes data already sorted according to billable entity and incorporates further data analysis means for dealing with data invalid by reason of pricing and charging related information.
Patent CA-2161796-A1 (CA)
Title: Hookworm anticoagulant
Inventor: CAPPELLO MICHAEL
IPC: A61K39/002
Filed: 1994-04-29
Abstract: A soluble anticoagulant protein isolated and purified from Ancylostoma hookworms markedly prolongs both the prothrombin time and partial thromboplastin time in clotting assays. The protein exhibits amino acid sequence homology to the Kunitz-type serine protease inhibitor family. Chromogenic peptide substrate and clotting time assays indicate that the protein inhibits extrinsic pathway clotting factor VIIa, the enzyme responsible for initiating the human coagulation cascade, and factor Xa in the common pathway of the coagulation cascade.

Patent CA-2170336-A1 (CA)
Title: Technique for closed loop servo operation in optical disc tracking
Inventor: CESHKOVSKY LUDWIG
IPC: G11B21/08
Filed: 1996-02-26
Abstract: The present invention allows the light beam of an optical disc storage device to radially move between different information tracks of an optical disc while the storage device tracking servo loop remains in a continuous closed loop mode of operation. The invention operates to radially move a light beam from one information track to another during a closed loop mode of operation by activating two control signals introduced into the closed tracking servo loop to create a phantom track center that radially moves across the optical disc. Because the tracking servo loop is in a closed loop mode of operation, the tracking servo operates to keep the light beam centered on the point that the tracking servo considers to be the center of an information track; in this case the phantom track center. Therefore, the tracking servo causes the light beam to radially move across the disc in a closed loop mode of operation by keeping the light beam centered on the moving phantom track center.

Patent CA-2174165-A1 (CA)
Title: A coupling
Inventor: HOLLANDS KEITH G M
IPC: F16L37/088
Filed: 1996-04-15
Abstract: A coupling, which may be an ostomy coupling but could be any kind of tube or pipe coupling, includes a first coupling member 10 and a second coupling member 30 which are mutually interengageable and which surround an orifice 70.    The coupling also includes a resilient split ring 50 which encircles the two coupling members and has a handle member 51 which can be manipulated to cause the split ring to be deformed. This causes the radially-inwardly extending tabs 52 on the ring to be shifted between respective first positions in which the split ring is undeformed and the tabs lock the two coupling members together and respective second positions in which the split ring is deformed in such a way as to shift the tabs radially outwardly to positions where they permit separation of the two coupling members.   The split ring is desirably made of a relatively rigid but springy plastics material, for example an acetal resin. The tabs carried by it are provided with curved or angled ramp surfaces which, when the ring is deformed by a force tending to rotate it relative to the coupling members, cause the tabs to be withdrawn from slots in one of the coupling members so permitting the two coupling members to be separated.

Inventor: LURIE KEITH G
IPC: A61M16/20
Filed: 1994-11-07
Abstract: This invention is methods and devices for impeding airflow into a patient's lungs during cardiopulmonary resuscitation to enhance the extent and duration of negative intrathoracic  pressure during decompression of the patient's chest.  In one embodiment, impeding the airflow into the patient's lungs is accomplished by placing a ventilation tube (36) in the patient's airway.  The ventilation tube contains either a flow restrictive orifice (50) disposed within or connected in series with a lumen of the ventilation tube, or a pressure responsive valve (44) within a lumen of the tube to impede the inflow of air.  In a preferred embodiment, the patient's mouth and nose are covered with a facial mask (52) which can impede air flow into the patient's airway.

Patent CA-2188054-A1 (CA)
Title: System for traffic information acquisition in vehicles
Inventor: GEDULD GEORG OTTO
IPC: G08G1/0967
Filed: 1995-04-06
Abstract: The invention concerns traffic information acquisition systems for vehicles, which systems have a first opto-electrical transceiver on the vehicle side and a second opto-electrical transceiver provided at predetermined locations in traffic lanes. The first transceiver emits a first signal and receives and decodes a second signal from the second transceiver. The second transceiver receives the first signal from the first transceiver and sends back a coded, second signal to the first transceiver.  The first transceiver is in the form of a reflection-operating time-distance measuring device. The emitted optical distance-measuring pulse signal is simultaneously the signal received by the second transceiver.  The second transceiver emits the second signal after a delay time following reception of the first signal. The delay time should be longer than the maximum amount of time required for a distance measurement.  It is thereby ensured that a signal from the second transceiver is not erroneously interpreted as a signal reflected by a target.

Title: Ropeway safety monitoring system
Inventor: FROHLICH SIGURD
IPC: G08B21/00
Filed: 1995-04-28
Abstract: A system for monitoring the safety of a ropeway includes sensors (12, 16) that communicate with a base station and preferrably a base station computer. A cable misalignment sensor (16) detects cable misalignments from a normal line of cable traction and produces a cable misalignment signal. A vibration sensor (12) on each sheave detects vibrations characteristic of disintegration in the sheave assembly and produces a vibration signal (14). These sensors each have an RF transmitter for broadcasting its signals to an RF receiver (16) on the cable towers. Interface units (4) local to sensor groups relay their signals to a base station computer to inform the cable operator. The transmitters and receivers are preferably spread spectrum to avoid interference. Interface units (4) and the base computer communicate via a common data network (6). Other types of sensors and codes to identify specific aspects of operation of the ropeway system are contemplated.
