The computer-implemented system to facilitate creation of educational information employs a networked computer system that stores at least one resource in association with a first electronic file, storing metadata information about usage of the resource. A resource assembly tool implemented by a computer is programmed to access the networked computer system to display information to an instructor about at least one resource, including the metadata information. This aids the instructor in selecting resources for inclusion in educational information being created. The resource assembly tool is configured to assemble the educational information to include resources selected for inclusion being created for dissemination to learners via said networked computer system. The networked computer system is further configured to capture information about usage of the resource and to update the stored metadata information to reflect said captured information.

A refrigerator has a cold storage and freezer zones with individual fans and evaporators, a switching valve that allows refrigerant to flow simultaneously through each zone or through only one of the zones and a control which when power is supplied causes simultaneous flow, starting the compressor and a condenser fan while driving the cold storage fan at a high speed and the freezing zone fan at a low speed until such time that a set point time has been exceeded or the temperature set points of the zones has been reached by cooling.

The present invention is a motorized shopping cart retriever that includes a controller that attenuates the power provided to the drive system of the retriever to prevent the retriever from being utilized to move an excessively heavy load of shopping carts. By preventing the retriever and carts from being subjected to overloaded conditions, the operational lives of the retriever and carts are maximized. The retriever is also provided with a burst mode that allows the power provided to the drive system to rapidly increase past the normal attenuated level for a brief period of time in order to reduce the time required to accelerate a retriever loaded with carts to a terminal velocity.

A method and a device for monitoring a rotational speed of a first charger for an internal combustion engine, especially an exhaust gas turbocharger, are provided. A first exhaust value representing an exhaust gas composition of the internal combustion engine in a first exhaust section is defined, and a first speed value representing the rotational speed of the first charger is determined according to the defined first exhaust value. The first exhaust value is regulated to a predefined first reference value using a first correcting variable which is ascertained as required for regulation. The first rotational speed value is determined depending on the first correcting variable.

It is disclosed a method for re-distributing subscriber sessions originated from one or more access nodes of a communication network to a number of service nodes of the communication network. The method comprises: monitoring at least one performance parameter of the service nodes; comparing a value of the at least one performance parameter with a threshold; and, in case the value exceeds the threshold at a given service node, determining a number of subscriber sessions to be moved from the given service node; selecting at least one further service node to re-establish the number of subscriber sessions; and re-configuring the communication network to move the number of subscriber sessions from the given service node to the at least one further service node.

The invention relates to a method which is used to adapt link weights or, link costs, for optimized traffic distribution within a communication network. According to said method, a loop is circulated until an interruption criterion is met. The individual iterations comprise the following steps: Routing of traffic within the communication network is calculated based on link cost paths. Parameter values used for optimization e.g. the link-related volume of traffic, are determined for the individual links by means of the calculated path, and an expected volume of traffic and the link are determined for the parameter having the highest value. When the highest determined value is equal to or less than the valve of the previous step (interruption criterion), the link costs are increased for the determined link. Said method enables link costs and paths for optimized traffic distribution to be determined in an economical manner.

The invention relates to a method and to a device that describe a real-time network plan for industrial control and monitoring applications, wherein standard Ethernet switching elements are used for the communication network, in particular on the basis of the new mechanisms according to the IEEE 802.1 TSN Task Group. The sequence plan combines clocked data transfer with the stream reservation concept and thus provides determinism with guaranteed maximum latency and access controls at runtime.

The invention relates to a well drilling fluid mixing and drifting tool, and belongs to the field of well drilling and logging in petroleum and natural gas industries. According to the well drilling fluid mixing and drifting tool, a logging instrument is effectively trapped into the downhole, and drifting operation is effectively completed. According to the technical scheme of the well drilling fluid mixing and drifting tool, a cable core at one end of a cable is connected with an electromagnet and a motor in a conducting mode, and a cable core at the other end of the cable is connected with aground electronic control platform in a conducting mode; the middle of the outer circle of a locking connector is in screw thread connection with the lower portion of an inner cavity of a locking nut, and the lower portion of the outer circle of the locking connector is in screw thread connection with the upper portion of an inner hole of a connecting head; the electromagnet is mounted on the upper portion of an inner cavity of an electromagnet sealing seat; an anchor jaw and an anchoring spring are overall arranged in a radial through hole in a centering wing of an anchor body; the upper endof an input magnetic tile seat and an output shaft of the motor are fixed through a transmission pin, the lower end of an inner cavity of an output magnetic tile seat is in screw thread connection with the upper end of the outer circle of a centering cylinder, and the upper end of a mixing head is in screw thread connection with the lower end of a transmission shaft. According to the well drilling fluid mixing and drifting tool, viscous well drilling fluid is electrically mixed, and thus the drifting effect is effectively achieved; and a magnetic driving technology is adopted, the motor and the electromagnet are sealed in a static sealing mode, and thus sealing is safe and reliable.

Embodiments of the present invention are directed to providing continuously updated completion time and an average completion time information for I / O commands on a per-LU, per-target, per-port basis. This measurement is performed by a kernel device driver that handles the I / O for the system at lower layers, so the measurements are more accurate because the delays due to higher level processing are not included. This approach allows the driver to track movements in the average I / O command completion time per LU and limit outstanding I / O counts early enough to potentially prevent overload conditions. By catching the overload early, the invention also has the ability to restore the original outstanding I / O count as the overload condition subsides.
