Patent CA-2232144-C (CA)
Title: Traffic shaper for network nodes and method thereof
Inventor: ELWALID ANWAR
IPC: H04L12/56
Filed: 1998-03-16
Granted: 2002-03-26
Abstract: The traffic shaping system according to the principles of the present invention increases the connection-carrying capacity of a network node by shaping the data cells to increase the admissible number of connections. In accordance with certain embodiments of the present invention, the traffic shaping system uses a data buffer at the ingress of the network node to selectively buffer classes of data cells. As such, the traffic shaping system exploits differences in delay tolerances between traffic classes to shape the less delay sensitive traffic classes to reduce the effective bandwidth of a connection of the particular traffic class and thereby increase the nodal connection-carrying capacity. Certain embodiments of the traffic shaping system operate within a framework to provide parameters for the traffic shaping system which increase the connection-carrying capacity for the node while meeting quality of service requirements for the data cells. In accordance with certain embodiments, an integrated regulator and shaper is provided which concurrently regulates and shapes the traffic cells to increase the nodal connection-carrying capacity.

Filed: 1998-10-08
Granted: 2003-12-09
Abstract: The voltage of each of battery block (50-1 ~ 50-n) of a battery (50) is detected by a voltage sensor (70-1 ~ 70-n).  Further, the temperature of the battery (50) is detected by a temperature sensor (74).  These detected values are supplied to a detecting section (80) of a battery ECU (68).  A judging section (82) reads out the threshold value of the voltage stored in a memory (84), on the basis of the detected values of temperature, and compares the threshold value of the voltage with the detected voltage of each of the battery blocks (50-1 ~ 50-n).  Then, if at least any one is less than the threshold value of the voltage, a relay (76)  is turned off.          Furthermore, the threshold value of the voltage is arranged to be the voltage at the moment when the value of the current is suddenly increased by the discharge of a constant current of the battery.

Abstract: An integrated computer-implemented corporate information delivery system. A  database stores research reports produced by and received electronically from brokerage firms. The database also stores corporate information about a number of corporations. Each item of corporate information is produced by and received electronically from one of the corporations about that corporation. Authorization information ("entitlements") specifies who is authorized to access each research report or item of corporate information. An entitlement subsystem allows the contributor of the research report or item of corporate information to dynamically change, on-line, the entitlement status of any or all users/subscribers. A reserach delivery module allows a user to submit a query and receive query results listing research reports and corporate information satisfying the query and that the user is authorized to access. A corporate register module outputs corporate information, the corporate information output according to a common format. The corporate information may be distributed via the Internet.
