An RF tag includes an IC chip and a dipole antenna both arranged on a dielectric base. The dipole antenna is composed of a pair of antenna patterns each of which is connected to respective feed points of the IC chip and extends in an opposite direction. When manufacturing the RF tag, length of the pair of antenna patterns is set so that the impedance matching between the IC chip and the dipole antenna is optimum in the air. When using the RF tag attached on an article, the extending ends of the antenna patterns are eliminated so that the length of the dipole antenna matches the wave-length of radio waves traveling through the article that the RF tag is attached.

Noise reduction for application of structural test patterns to a Device Under Test (DUT) is accomplished with a capacitor “booster” bypass network on the probe card in which the capacitors are charged to a much higher voltage Vboost than the DUT power supply voltage VDD. Charging the capacitors to a voltage N×VDD allows the buster network to store N times the charge of a conventionally configured capacitance network, and effectively provides N times the capacitance of the original network in the same physical space.

A virtual private network service provider, wherein virtual private network (“VPN”) software for setting up a virtual private network connection is delivered from a server computer to one or more client computers over a computer network, such as the Internet. Once the VPN software is delivered to the client computers, it can be executed so that data communications are made as virtual private network communications under control of the VPN software. Because the VPN software is stored and maintained on a server computer, and preferably delivered to the various client computers on an as-needed basis, the distribution, integrity and updating of the VPN software is improved because the “master” version of the VPN software can be controlled and revised by merely accessing the server computer system, rather than by attempting to control and revise numerous copies of the VPN software resident on various, scattered client computers.

The present invention provides drilling systems for drilling subsea wellbores. The drilling system includes a tubing that passes through a sea bottom wellhead and carries a drill bit. A drilling fluid system continuously supplies drilling fluid into the tubing, which discharges at the drill bit bottom and returns to the wellhead through an annulus between the tubing and the wellbore carrying the drill cuttings. A fluid return line extending from the wellhead equipment to the drilling vessel transports the returning fluid to the surface. In a riserless arrangement, the return fluid line is separate and spaced apart from the tubing. In a system using a riser, the return fluid line may be the riser or a separate line carried by the riser. The tubing may be coiled tubing with a drilling motor in the bottom hole assembly driving the drill bit. A suction pump coupled to the annulus is used to control the bottom hole pressure during drilling operations, making it possible to use heavier drilling muds and drill to greater depths than would be possible without the suction pump. An optional delivery system continuously injects a flowable material, whose fluid density is less than the density of the drilling fluid, into the returning fluid at one or more suitable locations the rate of such lighter material can be controlled to provide supplementary regulation of the pressure. Various pressure, temperature, flow rate and kick sensors included in the drilling system provide signals to a controller that controls the suction pump, the surface mud pump, a number of flow control devices, and the optional delivery system.
