摘要： Embodiments of a valve actuator are provided for adjusting the position of a main valve element in relation to the pressure of a fluid supplied by a supply duct. The valve actuator includes a housing, a control pressure valve disposed in the housing, and a piston slidably disposed in the housing and mechanically coupled to the main valve element. The housing has a control pressure chamber therein, which is configured to be fluidly coupled to the supply duct. The control pressure valve is configured to substantially impede fluid flow into the control pressure chamber until the fluid pressure within the supply duct surpasses a minimum actuation pressure. The piston normally resides in a first position and is configured to move toward a second position as the pressure within the control pressure chamber increases.

摘要： Disclosed is a multi-phase pulse width modulated voltage regulator and method in which transient voltage excursions or deviations that exceed the load line voltage by more than a pre-determined amount are detected by an ATR circuit and a correction signal is applied. The correction signal is in the form of asynchronous pulses and the number of such pulses is a function of the magnitude of the voltage excursion as determined by the number of thresholds that are exceeded. Also disclosed is an adaptive voltage positioning (AVP) circuit and method for early detection of a transient event by sensing voltage changes at the load and adjusting the target voltage with pre-determined current values prior to the time that ATR event changes in the current at the load are detected.

摘要： Reduction of administrative overhead in maintaining network information, rapid convergence on an optimal routing path through the data network, and utilization of only required network resources are realized by a novel method for establishing a call path between network users. The method is based upon deployment of a network information server that stores network topology information and that is addressable by each end user. In this method, the network information server receives a request to establish a call path. The request identifies at least the calling party. In response to the request, the network information server determines a network traversal between the calling party and a root network wherein the network traversal includes call path information about the sub-networks between the calling party and the root network. The request for establishing a call path can also identify the called party. Based on the calling and called party identification, the network information server also determines a second network traversal between the called party and the root network. The second network traversal is sent to either the calling party or the called party or to both the calling and called parties. The server can determine an intersection of the traversals and send the intersection information to the parties. The intersection information is known as a merge point and represents an optimal call path between the parties.

The connection carrier (33) is provided with the electrical contacts (34) such as bump electrodes each interconnecting a contact location (37) at the surface side of the connection carrier facing the semiconductor chip and the oppositely disposed (i) external pad on the chip or (ii) external pad or landing (35) at a side of the board (32) facing the connection carrier (33). Heat generated during operation is released through the rear side of the semiconductor chip (31r), which is affixed to the board or MCM (32).

摘要： A scroll compressor may be provided with a check valve interposed between a balance chamber and a discharge chamber. The check valve may allow balance chamber pressure to remain low during start-up of the compressor. Low balance chamber pressure may allow an orbiting scroll to remain unclamped to a fixed scroll thereby reducing torque required to initiate rotation of the orbiting scroll. After steady-state operational speed is reached the check valve may close and the scrolls may be clamped together to produce a desired steady-state operating condition for the compressor.
