摘要： A wireless sensor and actuator network includes a number of wireless nodes, each of which may be connected to any one or combination of analog sensors, digital sensors, and actuators, and is powered by an autonomous power supply such as a battery or solar panel. Since autonomous power sources may not have sufficient voltage for powering many types of analog sensors, digital sensors, and actuators, power management techniques are used in the node and in the autonomous power supply as needed to enable effective and long life operation of the node and connected devices. These power management techniques include the use of a low impedance energy reservoir and a variable voltage boost converter whose output voltage magnitude, duration, and operating times are software configurable and controllable. The power management techniques are particularly useful for operating a wide range of different types of sensors and actuators.

摘要： An ultra-miniature magnetic device generally comprises a conductive winding and a magnetic core. The conductive winding includes an upper conductor and a lower conductor. The magnetic core is of an elongate rectangular or oval shape having two elongate sections and two short sections. The lower conductor is preferably positioned below the elongate sections of the magnetic core while the upper conductor is preferably positioned above the elongate sections of the magnetic core. The lower and upper conductors are electrically connected by conducting via structures that are formed in sequential steps using semiconductor processing technology. The result is a coil winding around the elongate sections, with the short sections being preferably free of windings. The process provides an advantage of avoiding shorting between the via structures and the magnetic core caused by overetching when etching the via holes.

摘要： A current determiner having an output at which representations of input currents are provided comprising an input conductor for the input current and a current sensor supported on a substrate electrically isolated from one another but with the sensor positioned in the magnetic fields arising about the input conductor due to any input currents. The sensor extends along the substrate in a direction at an angle to the extent of the input conductor and is formed of at least a pair of thin-film ferromagnetic layers separated by a nonmagnetic layer with one of these two ferromagnetic thin-film layers having a magnetization that is substantially maintained in a selected direction despite the magnetic fields arising from the input currents causing reversals of direction of magnetization of that remaining one of these two ferromagnetic thin-film layers. This first current sensor is spaced apart from the input conductor at least in part by a polymeric electrical insulating material, and the input conductor can be provided on a mechanically stiff base supported on such material and provided with an electric field interrupter supporting such material between the first current sensor and the input conductor. The sensor can be electrically connected to a electronic circuitry formed in the substrate as a monolithic integrated circuit sharing a common reference, and two such monolithic integrated chips in a housing can provide duplex information signal transmission.

摘要： Apparatus and method for direct delivery of enabling chemical gas from a liquid source and of HF gas in a hydrogen fluoride/enabling chemical based cleaning or etching process, such as a silicon dioxide film etching process. The liquid enabling chemical is temperature controlled to generate a vapor pressure which is sufficient to operate a mass flow controller at a desired processing pressure without a carrier gas. Prior to entering the process chamber, the enabling chemical gas is pre-mixed with HF and optionally, a carrier gas, all of which are supplied at flow rates independent of each other. By controlling the vapor pressure of the solvent in this way, solvent/HF/carrier mixtures which are not physically possible with carrier gas systems are attainable allowing access to a larger process space.

摘要： Indicator light devices are useful in many applications for indicating properties of physical spaces respectively associated therewith and in physical proximity thereto. The indicator light devices are network-enabled and self-powered, and capable of participating in coordinated power-managed operation to provide a sufficient service life and lower installation and replacement costs. The indicator light devices may be used with or without associated sensors. The various embodiments described herein use various power management techniques singly or in combination to greatly increase the service life of self-power indicator light devices without diminishing their effectiveness in the application. These techniques include operating only the indicator light devices associated with the physical spaces having properties of interest, operating the indicator light devices with synchronized flashing, operating the indicator light devices in accordance with the detection of specific conditions, relevant time operation, in-vicinity activation, and ambient light responsiveness.

摘要： Apparatus and process for conditioning a generally planar substrate, contained in a chamber isolatable from the ambient environment and fed with a conditioning gas which includes reactive gas. The apparatus includes a support for supporting the substrate in the chamber, the substrate being in a lower pressure reaction region of the chamber. A gas inlet is provided for feeding conditioning gas into a gas inlet region of the chamber which is at a higher pressure than the lower pressure reaction region so that the pressure differential causes the conditioning gas to flow toward the surface of the substrate wherein the conditioning gas component will chemically react with and condition the substrate surface, both said higher and lower pressure regions operating in a viscous flow regime. The substrate is supported such that a pressure bias is created across the surface of this substrate so that the gas, after it has chemically reacted with the substrate surface, flows outward from where it has reacted, off the substrate toward the periphery of the chamber and out a peripheral or central underside exhaust outlet. Gas feed may be provided to one or both sides the substrate and light activation of the substrate or conditioning gas may be provided on one or both sides.
