摘要： A wiring layout design method and system providing efficient routing of wiring paths between multiple function blocks in an integrated circuit is disclosed. Associated with the function blocks are logic service terminals (LSTs) aligned on-grid relative to the global wiring layout. The technique utilizes a locator designating a desired contact point for each on-grid LST to be connected. The contact point designation is made without restriction relative to the predetermined grid pattern of the logic service terminals. Subsequent use of a conventional global wiring layout program to generate a layout of connections between LSTs, a reformatting program connects each wired logic service terminal to its desired contact point on the associated function block using the corresponding locator.

摘要： An electrosurgical cutting blade (1) comprises a first electrode (2), a second electrode (3), and an electrical insulator (4) separating the first and second electrodes. The first and second electrodes have dissimilar characteristics (cross-sectional area, thermal conductivity etc.) such that the first electrode (2) is encouraged to become an active electrode and the second electrode (3) is encouraged to become a return electrode. The spacing between the first and second electrodes (between 0.25 mm and 3.0 mm) and the peak voltage supplied to the electrodes (2 and 3) are both selected such that arcing does not occur directly between the electrodes, but between the first electrode and the tissue at the target site. The arrangement is such that, in use, a thermal differential of at least 50° C. is established between the first and second electrodes (2 and 3), such that the second electrode is maintained below a temperature of 70° C. This is achieved either by thermally insulating the second electrode from the first electrode, and/or by transferring heat away from the second electrode, e.g. by conduction, forced cooling, or by means of a heat pipe (27).

摘要： A device for morcellating tissue within a body cavity of a patient comprises a stationary tube having a distal end portion, and a bipolar electrosurgical electrode assembly located at the distal end of the tube. The electrosurgical electrode assembly comprises first and second electrodes separated by an insulation member, the bipolar electrosurgical electrode assembly extending around the circumference of the distal edge of the tube. When an electrosurgical cutting voltage is applied to the electrode assembly, and relative movement is initiated between the tube and the tissue, a core of severed tissue is formed within the tube such that it can be removed from the body cavity of the patient. A tissue-pulling device such as a jaw assembly can be employed to pull tissue against the distal end of the tube.

摘要： A miniaturized fluid dispensing system for dispensing customized fluids. The dispenser may include first and second reservoirs containing constituent fluids; a drive motor; at least two pump assemblies commonly driven by the drive motor and in communication with the first and second reservoirs; first and second valve assembly in communication with the first and second pump assemblies; and a control system for selectively controlling the valve assemblies to blend and discharge a composition from the constituent fluids. The system may include a dispensing header to house the valves and to define ‘discharge’ and ‘recirculation’ flow paths for each constituent fluid. The present invention also provides a method for dispensing a fluid regimen (e.g. a plurality of compositions) by periodically blending and discharging varying compositions over time.

摘要： A delay circuit for receiving a number of input signals and for providing a delay in accordance with the input signals. The delay circuit includes: an output circuit for producing a first output signal when a node is above a threshold voltage, and for producing a second output signal, which is different from the first output signal, when the node is below the threshold voltage; a device for maintaining the node voltage at a level which is above the threshold voltage so that the output circuit produces the first output signal; and a plurality of switching devices for causing, the node voltage to decrease below the threshold voltage so that the output circuit produces the second output signal. Depending on which one of the switching devices is rendered conductive, the node voltage will decrease at a different rate, thereby causing the output circuit to produce the second output signal at different delay times.

摘要： A device for morcellating tissue within a body cavity of a patient comprises a stationary tube (8) having a distal end portion (12), and a bipolar electrosurgical electrode assembly (13) located at the distal end of the tube. The electrosurgical electrode assembly (13) comprises first and second electrodes (14, 16) separated by an insulating member (15), the bipolar electrosurgical electrode assembly extending around the circumference of the distal edge of the tube (8). When a pulsed electrosurgical cutting voltage is applied to the electrode assembly (13) and relative movement is initiated between the tube (8) and the tissue, a core of severed tissue is formed within the tube such that it can be removed from the body cavity of the patient. Temperature sensors (60) can be used to measure the temperature at the distal end of the tube (8), and to vary the duty cycle of the pulsed cutting voltage.
