Title: Data segment driven afc latch for bi-phase stable frequency phase locked loop
Inventor: KRISHNAMURTHY GOPALAN
IPC: H03L7/10
Filed: 1995-03-31
Granted: 1999-12-07
Abstract: A dual mode AGC system for a television receiver in which data is in the form of symbols occurring at a fixed symbol rate.  The symbols are sent in successive data segments, each having a sync character.  Enablement of an AFC Defeat signal defines an initial interval during which the IF gain is maximum.  When the AFC Defeat signal becomes inactive, the receiver is operated in a non-coherent mode in which the gain of the IF amplifier is reduced incrementally whenever the IF signal exceeds a clipping level for a period of eight successive symbol clocks.  Upon a segment synclock condition occurring, a normal coherent mode is entered in which the AGC responds to a signal characteristic, i.e. data segment sync. The rate of gain change available in the non-coherent AGC mode is much greater than that in the normal coherent AGC mode.

Abstract: A low profile, bi-directionally snow-plowable road marker (15) having a cast metal base or body of generally square plan configuration formed on its underside with laterally spaced oppositely curved arcuate rib members (55) flanked by transversely extending webs (60) and protrusions (61) located centrally of the body and acting with the rib members to self-center the cast body in a shallow arcuate depression of single radius formed in a roadway pavement, the webs and protrusions being configured to evenly distribute adhesive over the bottom, sides, ends and over portions of the upper side of the cast body to encapsulate and lock the same securely in the pavement depression. The upper side of the cast body is distinguished by a pair of downwardly sloping sub road surface vision ramps extending inwardly of opposite ends of the cast body and terminating at their lower ends in co-planar mounting platforms which are separated by a vertically extending wall having a transversely protruding and overhanging canopy portion along its upper end. A reflective light signal assembly (17) is adapted to be mounted on either one or both of the platforms as selected, such being protectively captured and locked against vertical and lateral displacement by the overhanging canopy beneath which it is mounted. Locators having upper curvilinear surfaces and co-planar bottom surfaces are provided along opposite sides of the cast body to engage the roadway surface and thereby vertically locate the body casting in the pavement depression so that there is minimal protrusion of the marker above the roadway surface. The signal assemblies are protectively located on the bottom of the vision ramps and shielded from contact with vehicle tires and snowplow blades by the canopy.

Abstract: An "Intelligent" telecommunications network comprises a plurality of switching units interconnected by links, and connected to a central computer unit by a data communication system. For dynamic routing of a call, a first switching unit responds to a destination address in a call to attempt a direct link to a neighbouring switching unit and, in the event that the attempt is unsuccessful, issues to the central computer unit a message containing the destination address. The central computer unit uses the destination address to identify the unsuccessful link; (ii) updates a routing database to identify the link as unavailable; (iii) determines an alternative route for the call using a tandem node and (iv) compiles a return message including a network address for a tandem switching unit and transmits it to the first switching unit. The latter attempts to route the call via a link to the tandem unit which attempts to complete the call by a direct link to the destination switching unit. The tandem node switching unit also queries the central computer if it cannot complete the call by a direct link to the destination switching unit, whereupon the central computer will set to zero the idleness of the direct link which the tandem unit attempted and then determine an alternate route from the tandem unit to the destination, i.e. with the idleness factors of both direct links set to zero, resulting in an alternate route having three links.
