摘要:
Timing pulses are generated from operative synchronous data pulses by means of a crystal oscillator under direct control of the output signal of a D flip-flop. The flip-flop is set or reset depending on the phase of the clock pulse relative to the leading edge of the data pulse.

Various methods are provided to address the need for improved load balancing. In a one method, a packet loss is determined (101) for traffic sent between a first network node and a second network node. The determined packet loss is then used to determine (103) whether to perform load balancing. In another method, a first network node receives a request from a neighboring network node for a current loading status of the first network node. The first network node sends to the neighboring network node an indication of a backhaul loading level of the first network node.

A method of supporting access to a selected Internet Protocol (IP) multimedia application via an IP Multimedia Subsystem (IMS) is provided for a roaming mobile node (MN)—i.e., user equipment (UE)served by a wireless telecommunications system. The method includes: includes establishing a first IP tunnel between the UE and a local access gateway of a visited network, the first tunnel being anchored at the local access gateway; establishing a second IP tunnel between the UE and a home gateway of a home network, the second tunnel being anchored at the home gateway; receiving data packets at the local access gateway for the UE; filtering the packets received at the local access gateway to suitably classify corresponding traffic into one of a plurality of data flows supported within the first tunnel at varying Quality of Service (QoS) levels; and filtering the received packets.

The present invention is a system for controlling a pad conditioner in a CMP device. The system includes a roughness-sensing device mounted in proximity to a polishing pad. The roughness-sensing device generates an output responsive to a roughness of the polishing pad. A signal-processing unit then generates a roughness value of the polishing pad in response to the output from the roughness-sensing device, and generates a control signal in response to the generated roughness value. Finally, a control device controls motion of the pad conditioner in response to the control signal.

A functionally and structurally modular, parallelogram-shaped spacecraft. The spacecraft includes a plurality of modules joined to one another along an axis of the spacecraft, wherein each module is devoted to a particular function of the spacecraft, and wherein all of the modules have the same cross-sectional size and geometry. The geometry is approximately a parallelogram in a plane normal to the axis of the spacecraft. The functions include power, processing, propulsion, and the like.

A modular control system for an automated manufacturing facility, especially for use with a semiconductor fabrication facility having a number of discrete process components, provides a master control computer connected by a parallel bus to a series of modular interface cards. Each of the interface cards are organized to communicate with all the I/O located on a specific process component or group of process components. A plurality of daughter cards are provided on each of the interface cards. The daughter cards contain data translation and acquisition circuitry for translating the various forms of I/O signals from and into a database format. The signal list used to communicate between the master computer and the I/O is generated at startup, enabling easy modification, addition and deletion of I/O. Network-based communication protocols can also be employed for communication between the interface cards and the master computer.

A basic building block with rectangular projections d and a (FIG. 1) rising from the top center portion of the plane of bearing surface 42 (FIG. 4) being approximately one-eighth of the total height, labeled "d" and "H", respectively, in FIG. 3, the dimension "j" (FIG. 4) of the projection being somewhat less than the dimension "k" of the end of the block. The aforementionedprojection is symmetrical with the intersection of the longitudinal center line "X" and the traverse center line "Y" in FIG. 4.
摘要:
An internal combustion engine wherein each piston is relatively flat and is journalled to oscillate in a cavity defined by a sector of a cylinder. Thus, the piston forms two work chambers, one on each side of the piston, and each work chamber is equipped with appropriately timed intake and exhaust valves and one or more spark plugs.
