Abstract: More effective load balancing by a Server Load Balancer may be achieved by implementing extended Server Load Balancing information in a server. The extended Server Load Balancing information includes a special listing of “hot” objects, or objects that have been designated for special handling by the Server Load Balancer. In order to determine which objects on a server are “hot” at any particular point in time, the available throughput for the server is determined. This is then multiplied by a “hotness” percentage, resulting in an Object Threshold Value (OTV). Each of N objects is then assigned an Object Request Value (ORV), the N objects determined by taking the N objects utilizing the most bandwidth. The ORVs are then compared with the OTV, and any of the objects whose ORV exceeds the OTV are labeled as “hot”. Finally, information on the “hot” objects is communicated to the Server Load Balancer (SLB) for special handling.

Abstract: A data communications network with a plurality of PoPs maintains a local database associated with each PoP and a central database somewhere on the data communications network. The local database contains a group identification such as a domain identification corresponding to a group of users, a maximum number of proxied sessions to provide the group of users at the PoP and a dynamic proxy session count corresponding to active proxied sessions currently provided to the group of users at the PoP. The central database contains a maximum number of proxied sessions to provide the group of users over the entire data communications network and a dynamic network-wide proxy session count corresponding to active proxied sessions currently provided to the group of users on the entire data communications network. Actions are taken when the group attempts to exceed either the local maximum number of sessions or the network-wide maximum number of sessions by more than a predetermined number.

Abstract: The present invention, generally speaking, provides for high-efficiency power control of a high-efficiency (e.g., bard-limiting or switch-mode) power amplifier in such a manner as to achieve a desired control or modulation. Unlike the prior art, feedback is not required. That is, the amplifier may be controlled without continuous or frequent feedback adjustment. In one embodiment, the spread between a maximum frequency of the desired modulation and the operating frequency of a switch-mode DC-DC converter is reduced by following the switch-mode converter with an active linear regulator. The linear regulator is designed so as to control the operating voltage of the power amplifier with sufficient bandwidth to faithfully reproduce the desired amplitude modulation waveform. The linear regulator is further designed to reject variations on its input voltage even while the output voltage is changed in response to an applied control signal.

Abstract: For dispensing solder on a substrate, a soldering wire and a forming gas heated to a predetermined temperature are fed to a mixing chamber of a two-component nozzle so that, in the mixing chamber, solder is melted off and carried with the gas stream. The solder blown out of the two-component nozzle settles on the substrate. The two-component nozzle is moved or swivelled relative to the substrate in order to distribute the solder over a predetermined area of the substrate.

Abstract: The invention concerns a microsystem, in particular for producing microswitches or microvalves, constituted on a substrate (50) and used for producing a shift between a first operating state and a second operating state by means of a heat actuated device with bi-metal switch effect.

Abstract: A transmitter circuit improves a noise margin for decoding a common mode signal at a receiver circuit. The transmitter circuit includes a common mode signal transmitter and a noise margin enhancement circuit coupled to a transmission line. The common mode signal transmitter transmits a control message using a common mode signal. The common mode signal has a first voltage level and a second voltage level higher than the first voltage level, and the control message corresponds to a portion of the common mode signal having the first voltage level. The noise margin enhancement circuit raises a voltage level of the common mode signal to a third voltage level higher than the second voltage level for a specific time period from a rising edge of the common mode signal from the first voltage level.

The devices producing the synchronization signals have components placed in the channels of the final stage.

Abstract: A boundary scan cell of a driving integrated circuit transmits an AC signal to a boundary scan cell of a receiving integrated circuit. Both integrated circuits are AC coupled by a capacitor. The transmitted AC signal has a frequency lower than a cut-off frequency of the capacitor. A comparator coupled to the AC signal at the driving IC and the signal at the receiving IC compares both signals and determines whether the capacitor is short-circuited.

Abstract: A landing gear hinge shaft is installed on an aircraft structure using at least two ball joints (22), at least one of which is adjustable. The differences between the theoretical and real positions of the centers of the balls are measured, and the adjustments that have to be made to bring the centers of the balls back to their theoretical positions is deduced. This is done by making a first adjustment in the axial direction using a shim (30) and a second adjustment in the radial direction by adjusting the rotation of an inner cage (34) and an outer cage (36) of the ball joint. The inner and outer cages have eccentric axes that facilitate the adjustment.

Abstract: A method and an apparatus provide for determining whether a data terminal equipment (DTE) device represents a compatible device lacking an independent power supply and adapted to be powered using phantom power over a wired connection from a communications device such as a switch. A detection signal may be transmitted from the communications device to an identity network connected to the DTE. A response detection signal may be returned and checked in a receiver at the communications device. A switch may then be closed to provide phantom power if the result of the check indicates that the DTE is a compatible device adapted to receive phantom power. Compatible DTE device may include telephones, Voice over IP (VoIP, IP or Ethernet) telephones, network access devices, computers, and the like.

Abstract: A noise attenuating system includes a core portion adapted to actively filter sound waves into various bands, passing only those bands corresponding to safe amplitude sounds to a wearer's ear canal. Unlike conventional active noise cancellation systems, active noise attenuation is accomplished without providing additional sound waves inverse to unsafe amplitude sound waves. Instead, unsafe amplitude sound waves are passively blocked, and only safe amplitude sound waves are passed through to the wearer's ear canal.
