Granted: 1999-01-12
Abstract: An apparatus of the present invention can achieve an improved image quality, irrespective of either a still image or a motion image to be obtained, when a scanning line number is converted.  To this end, an interlaced scanning signal is input to a field delay circuit and to a vertical highpass filter, the output of the field delay circuit is input to a field delay circuit and to a vertical lowpass filter, and the output of the field delay circuit is input to a vertical highpass filter.  The outputs of the vertical highpass filters are added together at an adder.  The output of the adder is added by an adder to the output of the vertical lowpass filter to create an interpolation signal.  The interpolation signal and direct-type signal, being time-compressed, is coupled to a switch where they are alternately selected.  In this way, it is possible to create progressive scanning signals.

Abstract: A fishing jig is disclosed for holding a fishing rod and moving the rod in an upand down motion in an oscillating manner. The rod is oscillated by means of an electric motor that drives a jigging wheel and lever arrangement via a gear assembly which is connected to the jigging wheel. Both the rate of oscillation and oscillation stroke may be varied. Upon a strike by a fish, the jig has a mechanism for quickly raising the rod in an upward direction with sufficient force to set the hook. The distance that the rod travels to set the hook also may be adjusted. In addition, the sensitivity of the jig can be adjusted with regard to both the amount of force that must be exerted upon the fishing rod holder as a result of a fish strike and the degree of travel which the rod holder must undergo, as a result of a fish strike to activate the hook set mechanism. The jig may also be coupled to an alarm that indicates activation of the hook set mechanism.

Title: System and method for hierarchical multicast routing in atm networks
Inventor: CHEN XIAOQIANG
IPC: H04L12/56
Filed: 1997-02-24
Granted: 2002-01-01
Abstract: The present invention extends the PNNI protocols to support hierarchical multicast routing and signaling for ATM networks. The invention utilizes an extension to a core-based tree algorithm. Instead of a single core node, core nodes are maintained in each peer-group and at each level of the hierarchy. The advantage of this is that one single core node is not overloaded. Additionally, this increases fault-tolerance because there are no single points of failure. As would be understood, the present invention is highly scaleable because of the hierarchical nature of PNNI. In addition, the scheme supports multiple senders and dynamic membership changesto the multicast group. Quality of service requirements can be negotiated duringconnection setup and are guaranteed during the course of the connection. Though some additional topological information has to be flooded in the peer-groups to compute efficient multicast routes, the overheads to the connection management are minimal The multicast tree is built incrementally and the cost of the tree is comparable to the cost of the Steiner Tree computed using some standard heuristics.
