Patent CA-2516801-C (CA)
Inventor: SCHULTZ LYNN W
IPC: E01H5/06
Filed: 2005-08-22
Granted: 2013-02-19
Abstract: An improved snow plow blade is disclosed which has a fixed upper plow blade and a pivoting lower trip blade mounted on the swing frame of the snow plow with the axis of rotation of the trip blade being directly in line with the swing frame and the support frame of the snow plow. Since the axis of rotation of the trip edge blade is located at the height of the vertical center of the swing frame (and is thereby in the same horizontal plane), the forces imparted to the swing frame will be essentially compressive in nature rather than including a torsional element as well. The trip edge blade and the trip edge springs used to bias the trip edge blade into an untripped position are substantially supported by the swing frame of the snow plow rather than being supported from the upper plow blade. The trip ed4e blade is also sufficiently high to prevent damage to the upper snow plow blade due to impacts with curbs or other high obstacles.

Abstract: A method and system for recognizing text in computer images comprising distorted text provides an adaptive iterative process wherein recognition rules are adapted, added or omitted based on the present state of the recognition process. When the first pass through the recognition and adaptation is completed, the remaining unrecognized words (15) are passed through the recognition system 1 using the modified set of recognition rules stored in (18) and the process is repeated. In most cases the recognition system 1 will identify further reliable recognized words, which iteratively can be used to improve the recognition rules until the true text comprised in image (10) is recognized throughout the whole text. The steps of the method according to the present invention are thus repeated until convergence.

Abstract: A luminaire system having an elongated throughway utilizing a thermal chimney effect. The thermal chimney effect within the throughway circulates air to remove heat generated from the electrical components of the system. Dissipating heat into the throughway from the electrical components can increase the life expectancy of the lamp and the output of the lamp. The electrical components of the system being entirely sealed and isolated from the throughway results in a permanent air, dust, and water tight seal. The permanent seal can minimize damage to the electrical components of the system as well as prevent the build up of moisture and dust within these sealed components.

Filed: 2000-03-02
Granted: 2011-08-23
Abstract: A local area network using the telephone wiring within a residence or other building simultaneously with telephony signals. The local area network uses high pass filters to access the high-frequency band across the media, whereas the standard telephone service uses low pass filters to access the low-frequency voice / analog telephony band across the same media. The electrically- conducting media connecting telephone / data outlets are split, or separated at each outlet, and the outlets are modified to provide access to both ends of the resulting segments. The low pass filters at each segment end join the segments together, allowing analog telephony signals to travel throughout the network, thus supporting normal telephone service. The high pass filters at each segment end are connected to modems or other Data Communication Equipment, thus supporting data communication networks of various topologies, including point-to-point topologies.
