Filed:

May 24, 1999

Appl. No.:

09/317502

Assignee:

SIPEX Corporation - Billerica MA

International Classification:

G06F 1300

US Classification:

710300, 713323

Abstract:

A circuit and a method are presented which allow for the detection of an active communication device connected to the circuit. The circuit output signal can be used to reduce the power consumption of related equipment when communication is not detected for a predetermined period of time. The circuit includes a plurality of input terminals coupled to respective inactive detection blocks. The circuit also includes an accumulated delay block having delay circuits in serial electrical communication. Each inactive detection block provides a signal to a respective delay circuit that indicates whether the corresponding input terminal is connected to an active driver in the communication device. Each delay circuit provides a delayed output signal to a subsequent delay circuit. The accumulated delay block provides an output signal indicating the presence or absence of the communication device based on the activity at the input terminals over the predetermined period of time.

Assignee:

Sipex Corporation - Billerica MA

International Classification:

G05F 110

US Classification:

327536

Abstract:

Circuit and method for determining the presence of a load in a circuit including on a charge pump. The circuit monitors the state of a pump signal indicative of the operating status of the charge pump. The circuit generates a signal indicating the presence or absence of a load. The signal is used to deactivate features of an associated device, thereby reducing the power consumption and extending the life of the power supply (e. g. , battery) for the device.

Abstract:

A method for management of performance of computer systems and applications includes prompting the user to select information for monitoring, monitoring the performance of applications running on servers, displaying data, and prompting users to input performance adjustments. A user is prompted to select a server or server group, a resource, and a threshold or condition for notification, and in response a system compares the value or quality of the parameter to the threshold or condition, and provides a notification to the user in the event that the parameter reaches the threshold or condition. A method includes the steps of providing the user with performance information, receiving from the user a request for more specific performance information, and providing more detailed performance information. A method according to the invention includes the steps of receiving from the user an identification of a server as an authoritative server, another server as a comparison server, comparing runtime environment data in the form of one or more of CPU data, server data and Java data between the selected servers, and displaying differences to a user. A method of the invention includes the steps of receiving from the user an identification of a server as an authoritative server, and another server as a comparison server, and providing a list of matching and differing file names.
