Electrosurgical device

An improved surgical instrument having an end effector mounted on the end of an elongate shaft extending from a handle. The end-effector has different operations, including grasping, cutting, and sealing and / or coagulating tissue, and one of the operations is controlled by a drive handle mechanism. The drive handle mechanism includes an actuator, a drive shaft and a spring assembly for transferring movement of the actuator to the drive shaft, which in turn controls the end effector. The drive handle mechanism limits the amount of force transferred from the drive handle mechanism to the end effector, preventing damage to the tissue. As the actuator is operated, the spring assembly transfers the movement of the actuator to the drive shaft and the end effector. At the same time, the spring assembly compresses to absorb some of the force applied. Such configuration prevents the tissue being unintentionally damaged by the end effector.

Control of inductive power transfer pickups

InactiveUS6483202B1Reliable fail-safe control featureDecrease in saturation capacityRail devicesElectromagnetic wave systemDc currentEngineering
Secondary resonant pickup coils (102) used in loosely coupled inductive power transfer systems, with resonating capacitors (902) have high Q and could support large circulating currents which may destroy components. A current limit or "safety valve" uses an inductor designed to enter saturation at predetermined resonating currents somewhat above normal working levels. Saturation is immediate and passive. The constant-current characteristic of a loosely coupled, controlled pickup means that if the saturable section is shared by coupling flux and by leakage flux, then on saturation the current source is terminated in the saturated inductor, and little detuning from resonance occurs. Alternatively an external saturable inductor (1101, 1102) may be introduced within the resonant circuit (102 and 902), to detune the circuit away from the system frequency. Alternatively DC current may be passed through a winding to increase saturation of a saturable part of a core. As a result, a fail-safe pickup offering a voltage-limited constant-current output is provided.

Electro-optic window incorporating a discrete photovoltaic device and apparatus for making same

An electro-optic window is provided which is powered solely by at least one discrete photovoltaic cell within an electro-optic window. The electro-optic window has front and back spaced-apart glass elements sealably bonded together in a spaced-apart relationship and defining a chamber filled with an electro-optic material. The front glass element has a transparent conductive layer on the face of the front glass element confronting the rear glass element and the rear glass element has a transparent conductive layer on the face confronting the front glass element. The seal is generally disposed along the perimeter of three edges of both glass elements and some distance in from the remaining (fourth) edge. The photovoltaic assembly is electrically connected to the two transparent conductive layers and is placed on the outer perimeter along this fourth edge with the photon-absorbing side of all the photovoltaic cells within the photovoltaic assembly facing in one direction ("out" the window). When light impinges on the photovoltaic cell a current is created which darkens the electro-optic material in proportion to the amount of impinging light. By choosing the relative area of the photovoltaic assembly to produce the correct current for the electro-optically active window area, the darkening of the electro-optic portion can be directly and accurately controlled without the need for any circuit, wires or shorting resistors. In addition, an apparatus for making an electro-optic window having two members capable of securing and holding two glass elements in a spaced-apart and parallel relationship is provided. The glass elements may be secured by vacuum-applying members or simple clips. The glass elements may be held in a spaced-apart and parallel relationship by a hydraulic mechanism or by simple spacers placed between the securing members.

Compressor Valve Health Monitor

A rotating machine valve health monitor. Aspects of the valve monitor include instrumenting each valve of a reciprocating compressor, or other rotating machine, with a sensor capable of detecting at least vibration and instrumenting the crank shaft with a sensor capable of detecting at least rotation. A controller directly monitors the operation and condition of each valve to precisely identify any individual valve exhibiting leakage issues rather than only identifying the region of the leakage. The valve monitor uses a relatively high frequency stress wave analysis technique to provide a good signal-to-noise ratio to identify impact events indicative of leakage. The valve monitor uses circular waveforms of vibration data for individual valves to identify leakage by pattern recognition or visual identification. The valve monitor provides ongoing data collection to give warning of predicted valve failure and scheduling of preventative maintenance for failing valves.

Fabrication method of semiconductor wafer

A fabrication method of a semiconductor wafer can fill trenches formed in a semiconductor substrate with an epitaxial film with high crystal quality without leaving cavities in the trenches. The trenches are formed in the first conductivity type semiconductor substrate. Planes exposed inside the trenches are made clean surfaces by placing the substrate in a gas furnace, followed by supplying the furnace with an etching gas and carrier gas, and by performing etching on the exposed planes inside the trenches by a thickness from about a few nanometers to one micrometer. The trenches have a geometry opening upward through the etching. Following the etching, a second conductivity type semiconductor is epitaxially grown in the trenches by supplying the furnace with a growth gas, etching gas, doping gas and carrier gas, thereby filling the trenches. Instead of making the trenches slightly-opened upward, their sidewalls may be made planes enabling facet formation.

Method to regulate traffic congestion in a network

A method and system for controlling traffic on a network. A congestion indicator is generated by network components in response to the flow of network traffic. The congestion indicator is received by a network peripheral node that has a threshold variable which controls the flow of traffic flowing from the network peripheral node. The threshold variable corresponding to the congestion indicator will be reduced in order to restrict the flow of traffic flowing from that network peripheral node. If more than one congestion indicator is received by the network peripheral node, then the threshold variable will continue to be reduced thereby further restricting network traffic. If no further congestion indicators are received, then the network peripheral node will terminate the Back-Off Period state of the threshold variable such that the threshold variable can then be increased and network traffic can increase.
