Abstract: A user device may measure unidirectional latency of applications over asymmetric links. The user device may accurately measure application level unidirectional latency over cellular networks, without synchronizing system clocks. The user device may accurately measure the unidirectional latency in both an uplink direction and a downlink direction, without using a high-precision system clock and without synchronizing clocks between the user device and an application server.

Abstract: Techniques are described for managing power in a computing system using power controller(s). Power consumption information may be received from power sensors that measure power consumption of computing devices in a rack computing system, or that measure the power received or distributed by power distribution components such as power distribution units (PDUs) in the racks. A determination may be made whether the amount of power being currently consumed within a computing system exceeds a predetermined threshold. If so, control signal(s) may be sent to instruct the power controller(s) to alter characteristic(s), such as frequency, voltage, current, and so forth, of the power being supplied to one or more computing devices or other component(s). The power alteration may occur at one or more points in the power distribution system of one or more racks, such as at one or more PDUs, distribution circuits, breakers, and so forth.

Abstract: An air filter including a base and a first and second frame element is disclosed. Each frame element is coupled to the base. The frame elements have an oscillating shape having a first portion relatively close to the base and a second portion relatively farther from the base. A filter element generally follows the oscillating shape of the frame elements. An air filter system is also disclosed. The air filter system can include the air filter and an air filter container. The air filter container contains the air filter and directs air through the air filter in a predetermined direction. An air filter is disclosed including a support structure and an oscillating shaped filter element attached to the support structure. The oscillating shape increases the air filter surface area for a given volume.

Abstract: Network page latency reduction is facilitated by various embodiments. In one embodiment, a first distribution corresponding to a plurality of instances of a network page is estimated. A second distribution corresponding to a subset of the instances is also estimated. The network page is adapted based at least in part on a comparison of the first and second distributions in order to reduce network page latency.

Abstract: A system for generating electrical power includes one or more turbine systems, a linking system, a power receiving station, and a transmission line. The turbine systems includes a turbine, a turbine carrier that can hold the turbine in a flow of water, and a generator that produces electricity from rotation of a runner of the turbine. The linking system couples the turbine carriers to a fixed location. The transmission line transmits power from the generator to the power receiving station.

Abstract: A data processing system facilitates virtual machine migration with direct physical access control. The illustrative data processing system comprises a software-programmable trap control associated with hardware registers of a computer that selectively vectors execution control of a virtual machine (VM) between a host and a guest. The data processing system further comprises a logic which is configured for execution on the computer that programs the trap control to enable the virtual machine to directly access the hardware registers when the virtual machine is not migrated and to revoke direct access of the hardware registers in preparation for virtual machine migration.

Additionally, the system comprises a recommendation generator configured to generate a modification recommendation for the subset of the instances of the network page.

Abstract: A magnetic-stripe card, with an associated card-reader, provides the apparatus supporting a method to change the configuration of a printer, scanner, or, other peripheral device in a stand alone environment or in a networked environment. A network may be defined as “two or more devices communicating”. The method comprises programming the card with selected configuration data, such as character-font selection, serial baud-rate, or, in the case of a scanner, document-rotate, auto-stamp, scan-resolution, duplex-scan ON/OFF, and other parameters. The card may be swiped at a slot in the peripheral device directly, or through a portable reader, or, even from a reader permanently connected within a LAN. Data on the card alerts the device to be reconfigured of its intent by way of resident utility software on the device, and, within the host, if present. When the transaction is accepted, the data is transmitted to the selected device to rewrite selected configuration parameters.

Abstract: A unitary molded socket provides mounting for non-temperature compensated crystals, a resistor heating element for each crystal, and a thermistor. Each heating element is positioned adjacent a crystal housing for preventing the housing temperature from going below a given temperature. The thermistor is thermally coupled to one of the resistors for sensing its temperature and electrically coupled to control circuitry for providing the appropriate heating current to the resistor heating elements. A spring clip biases each crystal against its resistor, clamps it into the socket and is pivotable for replacement of components.
