Patent CA-2175489-C (CA)
Inventor: EMGE GARRY J
IPC: G06K15/02
Filed: 1994-10-06
Granted: 2000-08-22
Abstract: A technique for marking pixels on work-pieces by routing a scanned beam to different markings stations to mark individual pixels on selected ones of the workpieces.  Angular posi-tion of a scanning mirror in a raster scanner is determined by moving a beam, reflected from the scanner, across rulings on an optical ele-ment during scanning.  A print head for print-ing spots on a surface of a workpiece has a walled, internally pressurized chamber with an external curved surface and structure for causing an inked web to conform to the contour of the external curved surface and to be pulled along the external curved surface.  Two workpieces may be marked at two marking stations by two-directional scanning.

Abstract: A luminaire especially suited  for sports and roadway applications.  The reflector of the luminaire has a modified parabolic shape wherein a true parabolic curve has been tipped inwardly to produce a tipped parabolic reflector having a circle of focal points centered on the focal point of the original true parabolic curve.  The lamp comprises  a double-ended arc lamp which  is  positioned transversely of the central axis of the reflector with the arc of the lamp generally tangent to top dead center of the focal point circle.   The luminaire further includes a vertical black partition positioned within the reflector below and forwardly of the lamp and a specular insert in the upper front region of the reflector.  The front edge of the specular insert is generally contiguous with the rear edge of a flat upper portion of a visor positioned against the front face of the reflector with the specular insert angled upwardly with respect to the central axis of the reflector and the flat visor portion angled downwardly with respect to the central axis.  In an alternate embodiment a stepped lens is provided between the lamp and the front face of the reflector so as to block a direct frontal view of the arc.   In a further alternate embodiment a true parabolic reflector bowl in positioned in the back half of the  tipped  parabolic  reflector  to  provide  a  narrow concentrated beam.  In a further alternate embodiment, the clear lens that covers the front reflector face is replaced by a lateral spread lens to increase the beam width and reduce direct lamp glare.

Abstract: A peer-peer frequency hopping spread spectrum wireless system allows the implementation of full duplex voice/data communications in a single hop peer-peer wireless system.  The system uses frequency hopping spread spectrum technique.   The frequency band is divided into signalling and message channels.  The signalling channels use TDMA with a media access control(MAC) protocol developed for the wireless terminals to access the signalling channels.  Once a wireless terminal accesses a time slot on a signalling channel, the corresponding hopping pattern on the message channel is assigned.  The message channels use frequency hopping.  The hopping patterns of the message channel are chosen such that there is no co-channel interference and minimum adjacent channel interference in the system. Either analog or digital modulation schemes can be used. Synchronization of a transmitter-receiver pair (user-pair) and among user-pairs are achieved through the use of the signalling channels.

Abstract: Method includes the steps of (1) treating the textile with a predetermined amount of a non-durable sacrificial repellent material before putting the textile in service; (2) cleaning the textile with a mixture of a non-polar solvent and at least one cleaning additive to remove non-polar solvent soluble, insoluble and resistant contaminants from the textile; (3) washing the textile with a mixture of a polar solvent and at least one washing additive to remove polar solvent soluble contaminants from the textile; and (4) maintaining a predetermined amount of a non-durable sacrificial repellent material on the textile. The non-polar solvent may be perchloroethylene or the like, while the cleaning additive is a mixture of a dialkyl ketone, a carboxylic ester and a glycol ether. A second cleaning additive may be used to enhance contaminant removal. The polar solvent used is water, while the washing additive is a blend of surfactants.
