Patent CA-2022350-C (CA)
Title: Vertical phase adjust circuit
Inventor: RANDALL JENNIFER L
IPC: H03L7/00
Filed: 1990-07-31
Granted: 1996-01-02
Abstract: A vertical phase adjust circuit with high noise immunity for line locked surveillance cameras.  To prevent noise from the AC line producing false output signals, a counter is used to lock out the delayed vertical line locked output signal.  The horizontal scan frequency is counted from the time a vertical output is produced, and the vertical output signal is prevented until 98 percent of the period between legitimate vertical signals has elapsed.  The circuit also includes a lock detect circuit to increase the time window during startup conditions to assure initial synchronization and an increased phase adjust range to permit synchronization with any other camera.

Abstract: ABSTRACT           A marking tile is disclosed, for use in conjunction with pedestrian platforms and walkways.  The preferred embodiment of the tile has a plurality of buttons or longitudinal strips projecting upwardly therefrom to provide a distinctively textured upper surface.  The edges of the tile which are exposed to pedestrian traffic have a downwardly angled portion such that the height of the upper surface of the tile at the exposed edge is substantially at the height of the lower surface of the rest of the tile, so that the edge may be installed flush with the platform or walkway if the surface of the platform or walkway is bevelled beneath the angled portion.  An integral flange, preferably angled away from the vertical, projects downwardly from each exposed edge, for positioning in a groove of corresponding dimension to be cut into the platform or walkway.  The upward projections are of a lower height adjacent each exposed edge than elsewhere on the tile.  Where buttons are used, the button surfaces and the surface of the tile between the buttons are provided with a plurality of small upward projections to texture the surfaces.
