Patent CA-2245185-A1 (CA)
Title: Traffic safety prediction model
Inventor: KAUB ALAN RICHARD
IPC: G08G1/16
Filed: 1998-08-17
Abstract: The present invention provides an Traffic Safety prediction Computer Program (TRAF-SAFE) and sub-models for predicting the number of accidents, injuries and fatalities expected annually at an intersection or series of intersections based on the particular intersection and roadway features. A finite analysis approach to an intersection is used to break the intersection into discrete elements such as lanes, turnbays, stop control signals, and traffic flow rates. The total annual expected accidents can then be calculated as a summation of the interrelation of the individual elements. A Poisson's distribution is used to statistically estimate the likelihood of the individual vehicles occurring within a discrete time frame being investigated. The conflict probabilities between various permutations of the traffic flow is then calculated and summed to determine the number of conflicts for the intersection or roadway. The conflicts are then converted to expected accidents, and the accident level is converted to injury involvements and Safety Levels of Service for the intersection and roadway.

Title: Pressure relief valve and method of manufacturing the same
Inventor: FORSTER DARLENE E
IPC: B29C45/00
Filed: 1999-06-07
Abstract: A pressure relief valve such as is used to relieve over-pressure in the passenger compartment of an automotive vehicle has valve flaps which are retained in connection with a housing by molded-in-place retainer strips. The valve is manufactured by an injection molding tool having a pair of mold halves defining a first mold cavity for forming the housing and a second mold cavity for forming the flaps. After the housing and flaps have set, the mold is opened, with the housing remaining in contact with one mold half and the flaps remaining in contact with the other mold half. One mold half is then moved relative to the other to place the housing and the flaps in alignment with one another, and the mold halves are closed again to place the flaps inside the housing and define a third mold cavity extending along the lines of desired attachment between the flaps and the valve seats. A third quantity of thermoplastic material is injected into the third mold cavity where it sets to form the retainer strips, bonding with the edges of the flap and the adjacent edges of the valve seat. The third mold cavity also extends around a peripheral flange surrounding the housing, forming a seal which is bonded to the housing. The part is complete when ejected from the mold, with no additional assembly required.
Patent CA-2275591-A1 (CA)
Inventor: AHLBERG CHRISTER
IPC: H01P1/20
Filed: 1997-12-16
Abstract: The present invention relates generally to filtering in e.g. mobile telephony.  A new input loop is introduced wherein the input loop is fixed in its physical relation to the H-field. One end of this input loop is arranged to form a capacitance or an inductance which is then used to adjust the location of the maximum current node in the loop. The adjustment of the position of this maximum current node thereby adjusts the bandwidth of the RF signal. The fixing of the loop has the advantage of simplifying the procedure for tuning the filter. It also has the advantage of reducing the number of tools required for tuning, thereby allowing for a reduction in size occupied by the filter and isolator arrangement, and a reduction in the cabling and materials used.

Patent CA-2276978-A1 (CA)
Inventor: DERY DANIEL
IPC: B65G47/32
Filed: 1999-07-06
Abstract: The present transfer apparatus for elongated pieces, such as wood boards, beams, planks, etc., comprises an inlet conveyor, a loading device and an outlet conveyor. The inlet conveyor feeds in an abutting and side by side arrangement the boards to the loading device which separates the boards from one another and conveys them individually onto the outlet conveyor where the boards lie in a parallel and spaced relationship. The loading device comprises a rotatable drum defining a support surface and provided with an outwardly extending separation and lugging blade. A motor or the like rotates the drum about a rotation axis which is parallel to a direction of travel of the boards and perpendicular to a longitudinal axis of the boards as they are fed upstream of the loading device by the inlet conveyor.      The blade extends substantially helically about the drum with the drum and the blade being configured to allow a leading board to reach an upstream end of the support surface with the blade then separating as it rotates the leading board from upstream boards positioned on the inlet conveyor and causing the leading board to gradually translationally displace along the support surface and to a downstream end thereof where the leading board is discharged from the loading device onto the outlet conveyor. The blade also acts as a stop to prevent the upstream boards from being loaded onto the drum until the drum is ready to accept a new board, whereby the boards are fed one-by-one to the loading device. The blade is configured such that, for each rotation of the drum, one board is loaded onto the device.
