Session independent end to end route control is provided by coordination between a pair of route control devices. Each device determines whether received traffic qualifies for end to end route control and whether the device at the other end supports end to end route control. If so, then the route control devices determine a routing mode, such as tunneling or address translation, and routing parameters. The performance of the selected path is monitored and is changed if the performance becomes un...

Systems and methods for utility meter data collection on distributed metering systems. One aspect of the present invention provides quantity-interval or count-step based collection, reading, recording, and/or transmission of consumption data for distributed utility meter reading systems.

An evaporator includes a downwind-side heat exchanging part and an upwind-side heat exchanging part. In the heat exchanging part, paths are formed by partitions. In the evaporator, the flowing direction of coolant flowing in the upwind-side path is opposite to the flowing direction of the coolant flowing in the downwind-side path opposing to the upwind-side path. The number of heat exchanging passages in the path where the coolant rises is smaller than the number of heat exchanging passages in t...

A protocol-independent error-control system includes several components (840a, 830a, 820a, 150b, 820b, 830b, 840b) that assist in providing more reliable data transmission between endpoints (110, 120): 1) an ATM adaptation layer that supports quality-critical and time-critical data; 2) a rate converter that uses a priority scheme to adjust the data rate for different types of data; and 3) an error-control subsystem that implements a data link protocol optimized for error-prone links, and capable...

What is provided is a direct-current converter which improves unstableness of operations owing to an error of a bottom detection circuit and fluctuations of a detection point which are caused by disturbance. The direct-current converter includes a bottom detection circuit 13 which detects a minimum voltage of a main switch Q1 after an auxiliary switch Q2 is switched off, an ideal gate signal generation circuit 21 which generates an ideal gate signal for switching on the main switch Q1 at a time ...

The air-conditioner includes a compressor configured to compress and discharge a refrigerant. The air-conditioner includes a condenser configured to cool the refrigerant with air outside of a vehicle compartment. The air-conditioner includes a throttle configured to expand the refrigerant. The air-conditioner includes an evaporator configured to cool air inside of the vehicle compartment to eliminate moisture from the air by the expanded refrigerant. The air-conditioner includes a first refriger...

A software debugger adapted for connection to a hardware simulator simulating a hardware system includes a simulation information acquiring unit for acquiring cycle level execution information from the hardware simulator, and a debug processing unit for executing debugging by setting a processing width for time of one step execution instruction during debugging of a program executed on the hardware system based on the cycle level execution information.

In a two dimensional image recording and reproducing scheme, a position of a prescribed pattern in an information recording image that contains the prescribed pattern is detected by detecting a rough position of the prescribed pattern in the information recording image in units of pixel size, and then detecting a detailed position of the prescribed pattern in the information recording image in units less than the pixel size, according to the rough position and a center of gravity of a distributi...

In a wireless communication system formed by a plurality of access points constituting a wireless network, through which user terminals make accesses, and at least one control station configured to control the access points, public access points are systematically set up by a manager of the control station, while user's personal access points to be freely set up by users at desired locations according to needs of users are accommodated by operating the control station to measure a utilization le...

A coupling for a double tube is configured to connect with the double tube. The double tube includes an outer tube for a first fluid to flow therethrough. The double tube includes an inner tube provided inside of the outer tube and having an end protruding from the outer tube, the inner tube for a second fluid to flow therethrough. The coupling includes a branched portion brazed to an end of the outer tube and brazed to an end of the inner tube, with the end of the inner tube protruding outside ...
