Patent CA-2245308-A1 (CA)
Inventor: STEEN GREGORY G
IPC: B60R1/06
Filed: 1998-08-19
Abstract: An aerodynamic exterior rear view mirror for motor vehicles that has low drag as a result of prevention of laminar boundary layer separation on the mirror head and subsequent turbulent wake size reduction. The vehicle mirror comprises an aerodynamic exterior shell having a continuously smooth surface with inboard and outboard trailing edges. The surfaces of the shell preceding the trailing edges can be either parallel or closing relative to the free stream airflow. A boundary layer control device that consists of a trip strip isformed on the exterior surface of the mirror head just upstream of the transition or separation point where the laminar boundary layer flow would transition to turbulent boundary layer flow with delayed separation or to complete separation absent the boundary layer trip strip. The trip strip, when correctly sized and utilized, will assist the laminar boundary layer to transition to turbulent boundary layer flow which reenergizes the boundary layer. The turbulent boundary layer is more stable and has more energy which will enable it to adhere to the surface and allow the airflow to continue to and separate atthe mirror head trailing edges. As a result separation is greatly reduced or eliminated which reduces the drag that would have been present, absent the boundary layer control device.

Title: High-performance low-complexity error-correcting codes
Inventor: CROZIER STEWART
IPC: H03M13/45
Filed: 1998-08-14
Abstract: A method of encoding data is described herein. According to the method, source data elements are coded using one or more product codes having a common component code. The resulting one or more primary product codewords consist of a plurality of first codewords of the common component code. One or more first sets of codewords of the common component code are assembled such that each of the first sets comprises two or more distinct first codewords forming part of a same primary product codeword. Each of the codewords of each of the first sets is codeword-mapped to a second codeword of the common component code using a one-to-one codeword-mapping. One or more second sets of second codewords are provided, where each second set corresponds to a first set of codewords. The codeword-mapping includes re-ordering, according to a known interleaving pattern, the symbols within a codeword. The codeword-mappings are such that if all of the codewords of a first set are from a same primary product codeword, then some codeword-mappings applied to the codewords of the first set are different, and if two or more repetitions of a same codeword are included in a single first set, then the codeword-mappings applied to those repetitions are different. Each set of second codewords is coded using a systematic code so as to generate a secondary product codeword for a product code having as component codes the common component code and the systematic code. Then, the primary product codewords and the non- systematic portion of the secondary product codewords are provided as encoded output data.

Abstract: An improved seat belt gripping device is provided for clamping and locking the shoulder portion and lap portion of a seat belt together in order to adequately secure a child safety seat in place on a car seat. The device is tamper-resistant so that children will not be able to remove the device while in use and further the device is easy to use.      The safety device eliminates the need for removing slack from the shoulder portion of the seat belt in order to ensure that the child safety seat will not move in a forward direction during a sudden stop, collision or normal traffic maneuver.      The safety device features a C-shaped plate which includes two fingers. A removable middle finger is mounted between the two fingers to create an E-shaped configuration. Each finger of the C-shaped plate has a slot on its underside between the ends of the finger. The slots are dimensioned to accommodate the shoulder and lap portions of the seat belt, which extend transversely across the undersides of the two fingers. The middle finger may be mounted to the C-shaped plate by way of a threaded pin extending upward from the middle finger and a child-proof knob which threads on the pin. The user places the two adjacent seat belt portions over the middle finger and below the two fingers. The child-proof knob is then used to tighten and lock the C-shaped plate and the middle finger together thereby clamping the shoulder portion and the lap portion of the seat belt together.

Abstract: Fiber-reinforced resin pipe (10) fittings have a structural pipe wall (12) formed from helically wound reinforcing fiber that is bonded together with a polymer resin. An intermediate layer (16) is disposed around the structural pipe wall, and a fiber-reinforced resin layer (18) is disposed around the intermediate layer. The intermediate layer is formed from material selected from the group consisting of impact attenuating and impact absorbing materials. The fiber-reinforced resin layer comprises layers of helically wound reinforcing fiber bonded together with a polymer resin. The materials selected to form the fiber-reinforced resin layer can be the same or different from that used to form the structural pipe wall. The pipe may comprise a single intermediate and fiber-reinforced layer disposed around the structural pipe wall, or may comprise an impact resistant jacket disposed around the structural pipe wall, wherein the jacket is made up of alternating intermediate and fiber-reinforced resin layers. Fiber-reinforced resin pipes, constructed according to the principles of this invention, have improved impact resistance when compared to conventionally constructed fiber-reinforced resin pipes.

Abstract: A satellite-cellular communication system includes a satellite based transceiver for transceiving two-way communications originated at a user terminal. As a part of call set up, controller determines whether the user terminal should transmit in the uplink in either a wide band mode of operation or in a narrow band mode of operation. The controller then specifies to the user terminal the mode of operation through the transceiver. Whether the user terminal transmits in the uplink in a wide band or in a narrow band mode depends upon factors including the type of device, channel usage and efficiency in the channels to and from the satellite transceiver and the signal quality of the signals received at the transceiver.

Title: Methods of conferring ppo-inhibiting herbicide resistance to plants by gene manipulation
Inventor: GILLHAM NICHOLAS W
IPC: C12Q1/18
Filed: 1996-12-27
Abstract: The present invention provides methods to confer resistance to protoporphyrinogen-inhibiting herbicides onto crop plants. Resistance is conferred by genetically engineering the plants to express cloned DNA  encoding a protoporphyrinogen oxidase resistant to porphyric herbicides. If such resistant crop plants are cultivated, utilization of these herbicides on fields of these crop plants becomes feasible.  This should allow for simpler and more effective weed management, and increase the value of these herbicides for agricultural use.  Furthermore, the present invention provides plants, algae, plant cells, and algal cells which have been made resistant to protoporphyrinogen oxidase-inhibiting herbicides by the subject methods using a herbicide-resistant protoporphyrinogen oxidase gene that has been prepared by genetic engineering methods. In addition, the present invention provides methods to evaluate the inhibitory effects of test compounds on protoporphyrinogen oxidase activity, as well as methods to identify protoporphyrinogen oxidase inhibitors among test compounds. Preferred cloned DNA fragments encoding protoporphyrinogen oxidase enzymes resistant to porphyric herbicides are also described.
