Filed:

Feb 18, 2000

Appl. No.:

09/507304

Inventors:

David R. Coelho - Los Altos Hills CA
David B. Bernstein - San Mateo CA

Assignee:

Mobilesys, Inc. - Mountain View CA

International Classification:

G06F 1516

US Classification:

709246, 370913

Abstract:

A system to convert a network message into a wireless transport message includes a network-to-wireless transformation database with a message configuration table. An expansion agent processes a network message received from a computer network and information from the message configuration table to create a wireless transport message. The wireless transport message specifies attributes to facilitate the delivery of the network message to a wireless device. The attributes include a selected wireless message transport protocol and a selected wireless message transport conduit.

Assignee:

Silicon Clocks, Inc. - Fremont CA

International Classification:

H01L 23/34

US Classification:

310346, 310328, 310315, 310338

Abstract:

A MEMS structure having a temperature-compensated resonating member is described. The MEMS structure comprises a stress inverter member coupled with a substrate. A resonating member is housed in the stress inverter member and is suspended above the substrate. The MEMS stress inverter member is used to alter the thermal coefficient of frequency of the resonating member by inducing a stress on the resonating member in response to a change in temperature.

International Classification:

F16H 33/14

US Classification:

74 32, 74 2

Abstract:

A MEMS structure having a compensated resonating member is described. In an embodiment, a MEMS structure comprises a resonating member coupled to a substrate by an anchor. A dynamic mass-load is coupled with the resonating member. The dynamic mass-load is provided for compensating a change in frequency of the resonating member by altering the moment of inertia of the resonating member by way of a positional change relative to the anchor.

Silicon Laboratories Inc. - Austin TX

International Classification:

H01L 23/34

US Classification:

310346, 310328, 310367, 310370, 310361

Abstract:

A MEMS structure having a stress-inducer temperature-compensated resonator member is described. The MEMS structure includes a frame disposed above a substrate. The frame has an inner surface and an outer surface and is composed of a first material having a first coefficient of thermal expansion (CTE) and a second material having a second CTE, different from the first CTE. A resonator member is coupled to the inner surface of the frame.

Abstract:

A MEMS structure having a temperature-compensated resonator member is described. The MEMS structure comprises an asymmetric stress inverter member coupled with a substrate. A resonator member is housed in the asymmetric stress inverter member and is suspended above the substrate. The asymmetric stress inverter member is used to alter the thermal coefficient of frequency of the resonator member by inducing a stress on the resonator member in response to a change in temperature.

International Classification:

G06F015/16

US Classification:

709/207000

Abstract:

An optimized persistent messaging method and system repeatedly attempts delivery of a message by alternate delivery services that are capable of delivering a message if delivery by an initial delivery service fails, until either delivery is successful or else attempted delivery by all the delivery services has failed. The optimized persistent messaging method and system also prioritizes delivery services that are capable of delivering a message according to prioritization criteria from a variety of possible sources. The optimized persistent messaging method and system repeatedly attempts delivery beginning with the highest ranked delivery service and descending down a prioritized list of delivery services, until either delivery is successful or else attempted delivery by all the delivery services has failed.

International Classification:

G06F015/16

US Classification:

709224000, 709230000

Abstract:

Methods and systems for correlating network traffic between non-translative network systems are provided. Generally, time-based offset data, or transmission latency, is first determined between devices in non-translative network segments by injecting, with a time stamp, a known network pattern at a first end of the network topology. Traces are then recorded, with time stamps, of the network traffic over one or more nodes throughout the non-translative network. The generate network traffic is then compared to the traced network traffic in a best fit to thereby determine the time latency in traffic throughout the network. Later, when it is desired to determine causality of network activity between non-translative network segments, the determined latency between different network devices can be compared to traced patterns of network traffic to determine the origin of a network operation that created an observed event.

Abstract:

Methods and systems for correlating network traffic between non-translative network systems are provided. Generally, protocol cause and effect correlation rules are determined between devices in non-translative network segments by injecting a known network pattern at a first end of the network topology. Traces of the network traffic are then recorded over one or more nodes throughout the non-translative network. The generated network traffic is then compared to the traced network traffic by pattern matching to thereby determine protocol cause and effect correlation rules. Later, when it is desired to determine causality of network activity between non-translative network segments, the traced network patterns can be compared by pattern matching to the protocol cause and effect correlation rules to assist in determining the origin of a network operation that created an observed event.
