Patent CA-2184290-A1 (CA)
Inventor: KOST KAREN L
IPC: G06K7/10
Filed: 1995-03-01
Abstract: A graphical symbol  encoding  a nu-merical value may be accurately read even when placed on a non-planar surface.  The marker (120) is imaged with an inventive apparatus and analyzed using an inventive method which translates the graphical im-age into a unique number for article iden-tification purposes.  The marker (120) in its preferred embodiment includes an outer ring (210) having a continuous perimeter in one or more concentric data tracks disposed within this outer ring (210).  A timing track is used to determine angular relationships about the center of the marker.  Distances (D1-D4) between points associated  with the outer ring (210) in a particular data track are used in conjunction  with these angular relationships to locate a digitally encoded visual pattern associated  with a particular data  track.  This pattern is being used to store at least a portion of a numerical code used to identify each marker-bearing  arti-cle.

Patent CA-2208120-A1 (CA)
Title: Differential audio line receiver
Inventor: WHITLOCK WILLIAM E
IPC: H03F3/45
Filed: 1995-12-22
Abstract: A bootstrapped audio line receiver that receives a differential-mode input signal from first and second differential lines and outputs a single-ended signal on an output line. The line receiver includes a differential amplifier and an input amplifier having differential output terminals and differential input terminals. The input amplifier is connected between the differential lines and the differential amplifier. The input amplifier provides a dc current path to a ground terminal while maintaining a high input impedance to ac signals at audio frequencies.  The input amplifier also includes an rf filter that removes rf noise without adversely affecting the line receiver's common-mode noise rejection at audio frequencies. In one embodiment, the input amplifier includes two operational amplifiers connected for unity gain and having two bias resistors connected in series between each input terminals of the input amplifier and a ground terminal. A capacitor is connected from the output of each operational amplifier to a node between each set of series connected bias resistors and prevents the low impedance of the bias resistors from significantly degrading the line receiver's common-mode rejection ratio. Thus, the line receiver tolerates a wide range of balanced and unbalanced source impedances with a minimal deterioration of the line receiver's common-mode rejection ratio.

IPC: G08B13/196
Filed: 1996-07-26
Abstract: A video surveillance system (10) has a camera equipped with a fisheye lens (20) having a substantially hemispheric field of view. The system implements operations equivalent to the panning, tilting and zooming of a conventional camera without the use of moving parts. The lens (20) is mounted vertically above a plane under surveillance. The camera produces a fisheye image (14) made up of a plurality of pixels. The fisheye image (14) is distorted due to the properties of the fisheye lens (20). The system corrects the distortion by mapping the pixels of the fisheye image (14) to coordinates produced by selecting a particular part of the fisheye to be viewed.
Patent CA-2221156-A1 (CA)
Inventor: PICKLES JOHN DAVID
IPC: G05B19/18
Filed: 1996-07-10
Abstract: In a machine tool, a component such as a grinding wheel acts on a workpiece to form the latter into a circularly asymmetric shape, for example, a crankpin. Movement of the grinding wheel is controlled by a control signal which is derived from theoretical relative positions and positional velocities of the grinding wheel relative to the workpiece. In the course of at least one revolution of the workpiece, the respective positions of the grinding wheel relative to the workpiece are measured for each of a succession of angular positions of the workpiece. The measured positions are compared with corresponding theoretical positions and data indicative of any differences are stored, and then used to modify the control signal during a subsequent revolution of the workpiece so as to compensate for any of said differences and thereby reduce the magnitude of any error which would have resulted from the measured positional differences.

Abstract: Chuck for use with manual or powered driver having rotatable shaft, the chuck including a body member and jaws slidably positioned in angled passageways formed in the body. The chuck further includes a nut rotatably mounted relative to the body member and in engagement with threads on the jaws. A generally cylindrical front sleeve member is disposed in driving engagement with the nut and overlying the nose section of the body so that when the front sleeve member is rotated with respect to the body, the jaws will be moved thereby to grip the shaft of a tool. A spring member is biased to engage the sleeve member and is disposed selectively rotatably with respect to the nut. When the nut is tightened, the spring member becomes locked to the body member and restrains the nut from loosening during vibration of the chuck in use for its intended purpose.

Abstract: An integrated parking meter system automates the issuance of parking citations. Each parking meter will be equipped with a sonar range finder, mercur y type switch and a two way radio that communicates via N-PCS to a host computer back at the control center. When a meter runs out of money it checks to see if a vehicle is present in the parking space. If it is, the meter notifies the host c omputer that there is a car illegally parked in the space. The host computer correlates the information to identify the exact location of the violator. The host computer th en sends this information via wireless network to the parking meter attendants' personal communicator. The parking attendant proceeds to the violator and issues the citation. Included within this technology is the capability to remotely chan ge the rate structure of any or all electronic parking meters. A meter diagnostic featu re alerts repair personnel to specific malfunctioning meters. The meter may also se t the time remaining on the meter to zero whenever a car leaves the adjacent space .
