Title: Management system for routing information
Inventor: YOSHIMURA TOSHIHIDE
IPC: H04L12/40
Filed: 1994-02-21
Abstract: PURPOSE:To decide an optimum route in consideration of the delay situation between networks by providing a constitution where a notifying means notifies the calculated average effective delay degree of the communication data and the number of hops from another router to its own router and a managing means decides and manages an optimum route based on the notified delay degree and number of pops. CONSTITUTION:A router RF is connected to a network N1 and also to a circuit LEF, and the routing information IF is sent to a router RE from the router RF. The number of hops of information is decided when the router RF of the transmitting destination is viewed from a router of the transmitting destination. Then 1 is added to the number of hops of a table of the unupdated information IF. The router RE receives the information IF and performs comparison between the delay degrees of routing information on the network N1 of the transmitting destination. Then the routing information of a smaller delay degree is selected and changed into the number of received hops and average effective delay degree. Thus the contents of a routing information table TE1 are changed into those of a routing information table TE2. Repeating this operation, a managing means changes the contents of routing information tables of routers RA-RF to decide an optimum route.

Abstract: PURPOSE:To detect humidity without combining two constant current sources with each other by allowing the 1st temperature sensitive resistance for humidity detect to heat itself with a constant current and inputting its voltage to the 2nd temperature sensitive resistance, a resistance, and an operational amplifier which are connected in series. CONSTITUTION:A current from a constant current source I is inputted to the 1st temperature sensitive resistance H for humidity detection, which heats itself. The voltage across the resistance H is inputted to the inverted amplification input terminal of the operational amplifier OP through the resistance RC connected to the resistance N. Further, the amplifier OP is provided with a feedback resistance Rf for amplification. At this time, an output Vout is constant in a dry state because of a heat conduction coefficient hm is constant, but the hm increases owing to the generation of vapor as cooking progresses and the absolute value of the output Vout decreases. For the purpose, the circuit of the resistance N - amplifier OP is provided to eliminate the need to equalize temperature coefficients alphaH and alphaN of the resistances H and N, and humidity is detected only by adjusting the resistance RC, thereby detecting the finish of cooking in a microwave oven, etc.
