摘要:
A multi-sensor transducer and processing method allow insitu monitoring of the senor accuracy and transducer ‘health’. In one embodiment, the transducer has multiple sensors to provide corresponding output signals in response to a stimulus, such as pressure. A processor applies individual weight factors to reach of the output signals and provide a single transducer output that reduces the contribution from inaccurate sensors. The weight factors can be updated and stored. The processor can use the weight factors to provide a ‘health’ of the transducer based upon the number of accurate versus in-accurate sensors in the transducer.

Systems and method for providing digital data signals in conjunction with multiple satellite transponders are described. An uplink apparatus is configured to divide and recombine the digital data signal to generate a composite signal. The composite signal is then provided to a satellite and retransmitted by a plurality of satellite transponders to a content receiver. The content receiver is configured to recombine the plurality of transponder signals to regenerate the digital data signal.

The disclosure pertains to a space-conserving integrated fluid delivery system which is particularly useful for gas distribution in semiconductor processing equipment. The present invention also pertains to an integrated fluid flow network architecture, which may include, in addition to a layered substrate containing fluid flow channels, various fluid handling and monitoring components. The layered substrate is diffusion bonded, and the various fluid handling and monitoring components may be partially integrated or fully integrated into the substrate, depending on design and material requirements.

A method and apparatus for gas control is provided. The apparatus may be used for controlling gases delivered to a chamber, controlling the chamber pressure, controlling the delivery of backside gas between a substrate and substrate support and the like. In one embodiment, an apparatus for controlling gas control includes at least a first flow sensor having a control valve, a first pressure sensor and at least a second pressure sensor. An inlet of the first flow sensor is adapted for coupling to a gas supply. A control valve is coupled to an outlet of the flow sensor. The first pressure sensor is adapted to sense a metric indicative of the pressure upstream of the first flow sensor. The second pressure sensor is adapted to sense a metric indicative of the pressure downstream of the control valve.

A method and apparatus for treating a fluid to destroy, remove, or reduce undesirable agents, such as microorganisms, particles or ions, contained in the fluid and/or to inhibit the formation of scale are disclosed. The invention includes an apparatus for treating a fluid to destroy, remove, or reduce undesirable agents, such as microorganisms, particles, or ions, contained in the fluid and/or to inhibit the formation of scale. The apparatus can include an open fluid directional means or conduit. The preferred open fluid directional means is a conduit manufactured of resilient, corrosion-resistant material. The apparatus is attached to a power source and has a controller means. The controller means is desirably a microprocessor and can include a switching means for regulating the current to the apparatus. However, simpler circuits and components can be used for the controller means. The apparatus includes a field generating means. The field generating means forms a treatment field. The treatment field is a magnetic field and/or an electrical field in an effective dose sufficient to treat the fluid. The effective dose is determined by the exposure time(s) and strength(s) of the treatment field(s) and the concentration of contaminants present in the fluid subjected to the treatment.

Sputtering target lifetime is enhanced by providing a sputtering target assembly wherein a sputtering target is mounted to a substantially compliant cooling cover plate. The cooling cover plate is preferably fabricated from a plastic, a polymer, or a composite polymer and is provided with a plurality of grooves which form cooling fluid passages when the sputtering target is mounted to the cooling cover plate. These cooling fluid passages may be used to cool the target during sputtering. Because the cooling cover plate is substantially compliant, the sputtering target is free to bow in order to relieve any thermally induced strain produced within the sputtering target during sputtering. The lifetime of the sputtering target is thereby enhanced as both strain induced defect propagation/migration within the sputtering target, and the likelihood of sputtering target/cooling cover plate delamination are reduced.

The present disclosure is directed to a mobile machine, such as hydronic surface heater designed to be transported to a potentially remote worksite and operated for an extended period of time. The machine has a fueled component, such as a burner, fueled by a fuel supply system having at least two fuel tanks that are operably connected to one another by a connection line having an electronically controlled valve therein. The valve is coupled to the machine's electrical system, such as being coupled to the output of the machine's main breaker, so as to be opened whenever the machine is operating but to be otherwise closed. The fuel supply system thus has, in effect, a single tank when the machine is running and multiple separated tanks when the machine is not running. Fuel spill risks therefore are mitigated without having to sacrifice operating time and without significantly complicating the machine's fuel supply systems or its controls.
