IPC: H04J3/16
Filed: 2001-09-25
Abstract: A method is proposed for transmitting virtual containers of SDH or SONET  signals in which a group of AU-3s or AU-4s or AU-3-Nc's or AU-4-4c's is transmitted in a novel VC-Y-Xc transport module having an AU-PTR and an AU-POH for the group. The VC-Y-Xc transport module for SDH or SONET serves to form a group of virtual containers and has a PTR for the group, a POH for the group and a maximum of X-1 virtual container locations for transmitting tributary bits, where X is a natural number greater than 1 and Y is equal to 3 or 4 or a natural number greater than 1. For higher-order transmission channels, for example, VC-4s or VC-3s or also VC-4-Nc's or VC-3-3Nc's, a channel bundling is performed if said channels are transported jointly at least over ai subsection. The network management has only to manage, to protect and to switch the one bundle instead of a multiplicity of individual channels.

Title: Device including a micromechanical resonator having an operating frequency and method of extending same
Inventor: WANG KUN
IPC: H01H59/00
Filed: 2000-01-14
Abstract: A flexural-mode, micromechanical resonator utilizing a non-intrusive support structure to achieve measured Q's as high as 8,400 at VHF frequencies from 30-90 MHz is manufactured using polysilicon surface micromachining technology.  Also, a method for extending the operating frequency of the resonator as well as other types of micromechanical resonators is disclosed. One embodiment of the method is called a differential-signaling technique. The other embodiment of the method is called a dimple-down technique. The support structure includes one or more torsional-mode support springs (16) in the form of beams that effectively isolate a resonator beam from its anchors (18) via quarter-wavelength impedance transformations, minimizing anchor dissipation and allowing the resonator to achieve high Q with high stiffness in the VHF  frequency range. The resonator also includes one or more spacers (26) in the form of dimples formed on the flexural resonator beam (12) or the substrate.  In operation, the dimples (26) determine a capacitive-transducer gap of the resonator. When a large DC-bias voltage is applied between a drive electrode (20) and the resonator beam (12), the dimples (26) provide a predetermined minimum distance between the flexural resonator beam (12) and the drive electrode (20).

Title: Operational lever for bush cutter
Inventor: KOJIMA ATSUSHI
IPC: G05G5/04
Filed: 2001-12-06
Abstract: An operational lever for a bush cutter includes a handle housed in a handle case, a throttle lever pivotally mounted to the handle, and a lock lever pivotally mounted to the handle.      The operational lever further includes a torsion coil spring which exerts a resilient force on the lock lever. The lock lever is pivoted from an initial position to a pivoted position by an operator's palm. The throttle lever is then pivoted to a half-pivoted position by operator's fingers. When the palm is moved a small distance away from the handle case with the throttle lever held in the half-pivoted position, the lock lever is pivoted back towards the initial position by a resilient force of the spring. This causes a curved surface of a side protrusion portion of the lock lever to engage or abut on a side of a protrusion portion of the throttle lever. This arrangement is advantageous in that even when the operator takes her or his fingers off the throttle lever, the throttle lever is locked by a friction force produced between the curved surface and the side.

Abstract: A method for assaying specific binding between a fluorophore-labeled probe and an unlabeled target is provided.  The method includes detecting a quenching effect on fluorescence emitted by the fluorophore-labeled probe resulting from binding.  The method is conducted without separating complexes of the target and probe from the free target and free probe prior to quenching effect detecting, and without providing a signal quenching agent to quench fluorescent light. Preferably, the probe and target are amino acid-containing compounds, such as proteins. The method can be used for a variety of applications, including screening for drug candidates having optimum binding properties, and quantifying and classifying the binding characteristics between peptide-containing compounds. The method is more sensitive than conventional assays, enabling the analysis of minute samples and low affinity binding interactions between receptors and ligands that are below the detection limits of conventional technology.

Abstract: A monitoring system allows users to monitor the post-deployment performance of a web-based or other transactional server (30). The system includes an agent component ("agent") (32) which can be installed on agent computers (40) that have access to the transactional server (30), including computers of actual users of the transactional server (30). The agent (32) simulates the actions of actual users of the transactional server (30) while monitoring the server's performance. The specific transactions to be performed by the agent computers (40) are specified by testcases that are dispatched to the agent computers (40) using a controller (34). As each agent computer (40) executes a testcase, it reports the execution results (performance data) in real-time to a web-based reports server (36) which stores the results in a centralized database (42). The performance data may include, for example, server response times, screen display sequences for failed transactions, measured segment delays along network paths, and identifiers of "broken" web site links. Authorized personnel can access the reports server (36) using a standard web browser to view the collected performance data via a series of customizable reports.  Using the controller (34), the user can also assign testcase execution schedules to the agent computers (40), including periodic schedules that provide for continuous or near-continuous monitoring of the transactional server (30). In addition, the user can specify alert conditions which cause personnel to be immediately notified (e.g., by pager) of problems. The controller (34) and the reports server (36) also provide functions for allowing the user to monitor the operation of the transactional server (30) according to the attributes of the agent computers (40), such as the locations, organizations, and ISPs of such computers.
