In a business network environment, each workstation or information access point (IAP) has installed thereon a quality of service (QoS) module to monitor the IAP's performance. The QoS module declares exceptions when it perceives that one or more of a predetermined plurality of functions or conditions of the computer has entered into a state indicative of degraded performance. At the time that an exception is declared, a snapshot is taken of the software applications running on the IAP, the amount of resources that they are using, and presence or absence of the user. As used in calculating a QoS index representative of the operational state of the IAP, exceptions are weighted to take into account the relative importance of these exceptions and the users which they affect. Because the QoS indices are time-normalized, they may be aggregated or compared across the network by an IT administrator.

A system for weighing a plurality of quadruped animals is for use in a pen confining the animals. The pen has at least first and second segregated spaces with a first one-way chute allowing animal passage from the second space to the first space. A weighing station is located within a passage having an entrance and an exit, and that allows animal passage from the first area to the second area. The weighing station includes a weighing platform within the passage over which an animal must pass when passing from the first to the second space. The weighing platform has inlet and exit scales that support the weighing platform adjacent to inlet and exit ends thereof, and provides inlet and exit weight signals. A controller receives the inlet and exit weight signals and uses them in an iterative process to determine the presence of a single animal on the weighing platform. Once that determination is made, the sum of the inlet and exit weight values is very likely to accurately provide the animal weight. The controller may also use the inlet and exit weight signals to control closing of an inlet gate to bar more than one animal at a time from the weighing platform. An animal sorting system can easily incorporate this weighing system to provide more accurate sorting.

The contents of stabilizers for archery bows in the past have been a non-removable material that is permanently sealed inside the stabilizer housing unit by the manufacturer. Most stabilizers are made from tubular aluminum or other lightweight materials. The inside contents of the tubular stabilizers vary, such as fluid, granular steel, granular rubber, lead or solid elastomer, none of which can be moved around, altered or removed or added to by the archer. A unique feature of this device is that the housing of the stabilizer can be easily opened and re-closed securely by the archer, enabling the archer to remove, replace, adjust, change, add to or subtract from the contents, in order to get the exact desired weight, balance and / or vibration and sound dampening effect. An additional unique feature of this design is that the contents can consist of weighted material inside removable soft elastomer modular units of various sizes and / or mass weights. The weighted material can be made of steel or lead shot, ball bearings, weight rods, capsules filled with fluid, or fluid plus weighted pellets, or any combination of these weighted materials. Any or all of these can be suspended and / or sealed or molded inside the soft elastomer modules. This weighted material and / or fluid suspended in the elastomer absorbs vibration and sound, and the vibration and sound then is dissipated and absorbed further by the elastomer, then by the stabilizer housing itself. The archer can use different sized and / or weighted sections or internal modules, packets, that fit and / or stack snugly inside the housing of the stabilizer. The archer can change them easily, at will, to get the desired weight, balance and / or amount of vibration and sound dampening. The size and weight of these removable internal vibration dampening modules are only limited by the inside volume of the hollow chamber of the stabilizer housing that attaches to the bow. Another unique feature of this design is that two or more stabilizer housing of the same or varying sizes and shapes can be joined together, with or without an O-ring compressed between the stabilizer housings, to make one longer modular stabilizer with adjustable internal variable weight components. Also, a system of offset brackets and / or V-bars can be used to secure one or more of these stabilizer units in a position not normally available because of the limitations and configuration of a particular archery bow handle / riser.

A GNSS navigation system and navigation method for determining user position, user velocity, and improved uncertainty metrics for position and velocity. A measurement engine in an applications processor of the system determines pseudorange and delta range values over each time period for each received satellite signal, and also determines measurement noise variances for both pseudorange and delta range for the individual signals. The satellite-specific pseudorange and delta range measurement variances are used to determine the position and velocity uncertainties by a position engine, either by way of a least-squares linearization or by way of an enhanced Kalman filter. The uncertainties may be communicated to the system user, or used in generating an integrated position and velocity result from both the GNSS navigation function and an inertial navigation system result.

This invention relates to an improved apparatus for measuring the weight of an object being carried by a fork lift truck. Accurate weight is obtained by combining the measurements of the tension load(s) exerted by the chain(s) used to lift and support the fork carrying carriage with a measurement of the vertical forces imposed on the carriage by the mast through the carriage guides that are used to contain carriage movement within the mast and support the moment created by the object being weighed. The weight thusly determined can be easily calibrated for both pitch and roll mast angles. The apparatus can be integrated into the mast system of the fork truck without significantly affecting the fork truck's load carrying capacity. Specifically, the scale apparatus does not increase the overturning moment created by the weight of the object as compared with that of the standard non-instrumented carriage.

An apparatus and method for displaying the weight or cost of segments of an irregularly shaped item involves passing a sensor bar supported above a supporting surface over the item lying on the surface. A compact hand-held embodiment of the sensor bar enables the operator to move the sensor bar in various linear or non-linear motions over the item surface as the sensor bar moves laterally across the item surface while the sensor bar support posts remain in constant contact with the supporting surface. The sensor bar contains one or more sensors which generate signals corresponding to the height of the item as the sensor bar traverses the item. At the same time, a displacement detector arrangement generates signals corresponding to displacement of the sensor bar relative to the support surface. These signals are processed in a signal processor to determine the volume of an uncut segment of the item lying behind the sensor bar at successive positions. Each of these cumulative volume determinations may be continuously converted into numeric weight values based on the density factor for the particular type of item, whereby numeric weight and cost values (based on weight) are continuously displayed as the sensor bar is stroked over the item, thus enabling the operator to accommodate an on-looking consumer's specific requests as per the particular portion desired based on the physical appearance, weight, and cost of an item before the item is cut.

In this application, the invention is a novel heuristic mechanism of working path and backup path reservation for highly utilizable WDM mesh networks, which we call dynamic-network adapted cost selection (DAC-selection) mechanism. One of its characteristics is simple traffic distribution mechanism, and the performance of DAC-selection mechanism is superior to that of Random selection (R-selection) and Advanced Combined Min-cost selection (ACM-selection) mechanism. DAC-selection mechanism provides simple cost function by assigning proper weights to each component of the cost function and the total cost is obtained by just summing up the individual cost. Therefore, it is possible to select a best pair of working path and backup path which consumes least wavelength for reservation.
