Title: X-ray image processing
Inventor: LIN ZHONGMIN
IPC: G01N23/04
Filed: 1998-06-23
Abstract: An object (130) to be imaged is positioned between an x-ray source (100) and an x-ray imager (140). The x-ray source (100) is operated to direct x-rays (120) through and around the object (130). Electrical signals representative of the intensity of the x-rays (120) impinging on the x-ray imager (140) are used to locate a boundary of the object (130), and an x-ray image is generated using this boundary. Alternatively or additionally, an x-ray image is generated using the highest frequency magnitude in the set of electrical signals.

Title: Quarter for skate boot
Inventor: CHENEVERT FRANCOIS
IPC: A43B23/04
Filed: 1998-09-04
Abstract: A one-piece quarter for a lasted skate boot. It comprises a quarter medial portion (11), and a quarter lateral portion (13). The quarter medial portion and lateral portion comprise respectively a foxing medial (12) and lateral portions (14). The junction line (15) between the lateral and medial portions defines a symmetry line. A tendon guard (20) is disposed in the upper portion of the quarter. This tendon guard is preferably sewn to the quarter. The guard is therefore attached to the quarter, along with the junction line (21).  According to the invention, with a quarter consisting of only one piece, there is no sewing line along the symmetry line. The skate boot provided with such a quarter features a stronger heel portion, without any risk of broken sewing line. It is less expensive to manufacture, with at least one sewing step eliminated.
Patent CA-2305390-A1 (CA)
Inventor: KOOISTRA HESSEL III
IPC: G08G1/017
Filed: 1997-10-28
Abstract: A traffic law enforcement system (18) having one or more enforcement units (20) and decoy units (22), and an engagement mechanism (24) corresponding to each enforcement unit and decoy unit. The enforcement units are capable of vehicle speed detection (30) and identification to enable enforcement of the speed limits by subsequent ticketing. The decoy units have an external appearance substantially indistinguishable from an enforcement unit. Both decoy units and enforcement units are preferably positioned in prominent, highly-visible locations throughout a traffic flow area. The engagement mechanism enables the substitution of enforcement units for decoy units, and vice versa. This enables routine and random exchanging of decoy units and enforcement units which increases the difficulty of a driver discriminating between enforcement units and decoy units, decreasing the number of enforcement units required in the system, and, therefore, the cost of the entire system. The invention provides a means of helping reduce the speed of drivers to safe limits while enabling more effective and safer enforcement of the traffic ordinances by requiring less police interaction and the dedication of fewer police resources, such as police cars and related enforcement equipment. Such a system will play an important role in permitting municipalities to dedicate police resources to the enforcement of more serious criminal laws, or, alternatively, to reduce the municipalities' traffic law enforcement costs.

Patent CA-2330300-A1 (CA)
Inventor: BRADLEY ROBERT M
IPC: H01R13/6581
Filed: 1999-04-28
Abstract: Disclosed is an electrical interconnect system using multiple grounding methods to reduce or prevent spurious signals from interfering with high density contacts carrying high speed transmissions. A first connector includes an insulative pillar partially surrounded by a plurality of signal contacts. A ground contact is at least partially located within the insulative pillar. A second connector includes a corresponding plurality of flexible signal contacts for mating with the signal contacts adjacent the insulative pillar. The second connector also includes a ground contact for receiving the ground contact of the first connector. The ground contacts provide a first method of providing a ground path to reduce spurious signals from entering the signal path. An electrically conduction shield is located outside the signal contacts when the first and the second connectors are mated. The first connector includes a member which provides a ground path between the first connector and the electrically conducting shield. Advantageously, the electrical interconnect system has two grounding methods which are particularly important in a high density electrical interconnect system where the contacts are closely spaced and susceptible to noise and other spurious signals.
