Abstract: PURPOSE: A method for deciding a relay signal protocol in a B-ISDN(Broad-Integrated Services Digital Network) exchange node is provided to correctly supply information necessary for adding or deleting a relay network selection information. Also, it is possible to decide the relay signal protocol according to network identifying information of direct root or bypass root information. CONSTITUTION: A system generates root information of the next node for being used when an outgoing relay is performed by a fixed rooting method supporting a resource capacity requested from a root number, a network identifying number of the next node and a call setup request message. The system receives the call setup request message. If the message is decided as an outgoing relay call through a number translation, the system confirms whether a provider network of the next node uses the same protocol from the network identifying information of the selected root information. If so, the system uses the same protocol, and transmits the call setup request message to the next node. If a provider network of the next node does not use the same protocol, the system uses a protocol of the operator network, and transmits the call setup message to the next node.

Abstract: PURPOSE: A method for compressing, searching and inserting new items considering memory hierarchy structure is provided to increase a velocity of a multiple searching tree by using one pointer in one node, thereby identifying (the number of a key x the size of the key + pointer size) with a size of a cache line. CONSTITUTION: If a new item process is started(S601), a position to be appended by a new item is searched(S602), and the new item is appended to a node thereof. In addition, if the node is full, a medium value is appended to a parent node, and child nodes are divided into and inserted in two consecutive memories(S603). A process to be appended in the parent node is identified with a method to be appended to the current node. If a specific node deletion process is started(S604), a position to be deleted is searched(S605), and the corresponding item is deleted from the corresponding node(S606). As the result of the deletion, if the number of items of the corresponding node is decreased less than the half thereof, the node is integrated to an adjacent node, and the two consecutive memories having children of two nodes are integrated as one consecutive memory. If two adjacent nodes are integrated caused by a deletion, an item indicating the integrated node is deleted. If the number of items of the parent node is decreased, the process is repeated. If a searching process is started, the searching result is obtained by the above (S602) and (S605) stages.

Title: Power-up detector for low power systems
Inventor: SANDHU BAL S
IPC: H03K17/22
Filed: 1997-07-24
Abstract: PURPOSE: Power-up reset circuit which is independent of the slew rate of the power supply voltage, which does not depend upon the beta ration between back-to-back inverters and which relies primarily upon transistor threshold voltages for setting internal threshold levels is provided. CONSTITUTION: When power is initially applied to the supply voltage line(20), power-updetector(14) generates a signal on line(28) which is applied to temporarily disable amplifier(16), and a signal on line(32) to temporarily maintain transistor(M1) in an ON state. As the voltage level on the supply voltage line 20 rises further, current mirror(12) becomes operable and provides an output signal on line(22) and an enable (or control signal) signal on line(24). The output signal on line(22) disables the power detector(14) and overrides its disable signal on line(28), and the enable signal on line(32). At the same time, the output signal on line(22) is amplified by amplifier 16 which at the same time is enabled by the enable signal on line(24). The amplified signal from amplifier 16 operates to enable the output-driver/power-down stage(18), which in turn provides the reset output of the overall circuit, and also disables transistor(M1) by applying a disable signal to the gate of transistor(M1) via line(26) after the power up trip point voltage is reached. This removes power from the current mirror(12), power detector(14), and amplifier(16) circuitry, to reduce the power consumed thereafter by the power-up reset circuit of the present invention.
