A drive system (20) for driving a driven member (18), such as a print head of an offset printing system includes a motor (170) and a pivotable linkage (180) which allows relative pivoting between the driven member and the drive system. The pivotable linkage is operatively connected with the motor for advancing the driven member.

An electrosurgical biopsy device includes a stylet and a cannula movably mounted on a base. The stylet has a shaft with a head at its distal end and a stylet ablation element extending distally from the head. The stylet shaft is disposed through the cannula for axial translation therein between withdrawn and extended positions. The cannula has an opening at its distal end and a tissue cutting element adjacent the opening. Both ablation elements are activatable with energy that ablates adjacent tissue. A translation mechanism controllably moves (a) the stylet between the withdrawn and extended positions end (b) the cannula between a proximal position and a distal position relative to the base.

A mixing module for use in a dispenser system having a housing with a front end, a rear end and an interior opening between the front and rear end, and the housing having a cap covering at the front end. A rod and a mixing chamber are received within the interior opening in the housing and have a rod reception passageway which receives the rod. The mixing module has at least one chemical inlet opening into the rod reception passageway, and the rod is adjustably received within the rod reception passageway with a forward end of travel that places the rod at the front end of the housing. A solvent feed passageway extends in a rearward to forward direction entirely within a wall portion of the housing. There is also a cap covering the housing defining a solvent feed space (e.g., a double wall combination) at the front end with the solvent feed space extending radially inward for solvent feed to the rod upon rod positioning at the front end).

An instrument for compacting bone material is provided. The instrument includes a first component defining a longitudinal axis of the first component and a second component. The second component is moveably associated with the first component. The second component is moveable at least partially in a radial direction outwardly from the longitudinal axis of the first component.

Resource management architectures implemented in computer systems to manage resources are described. In one embodiment, a general architecture includes a resource manager and multiple resource providers that support one or more resource consumers such as a system component or application. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The resource manager arbitrates access to the resources provided by the resource providers on behalf of the consumers. A policy manager sets various policies that are used by the resource manager to allocate resources. One policy is a priority-based policy that distinguishes among which applications and/or users have priority over others to use the resources. A resource consumer creates an “activity” at the resource manager and builds one or more “configurations” that describe various sets of preferred resources required to perform the activity. Each resource consumer can specify one or more configurations for each activity. If multiple configurations are specified, the resource consumer can rank them according to preference. This allows the resource consumers to be dynamically changed from one configuration to another as operating conditions change.

The present invention relates to a modified intake manifold having short runner valves in the manifold tuning valve. Anti-chatter devices are disclosed for reducing shaft chatter without placing friction on the shafts. A lost motion linkage is used to ensure closure of the short runner valves. Radiused seating surfaces are used for seating of the manifold tuning valve.

A planarization composition is set forth for chemical mechanical planarization of dielectric layers for semiconductor manufacture. The composition comprises spherical silica particles having an average diameter of from 30 nm to about 400 nm, and a narrow range of particle sizes, wherein about 90% of the particles is within 20% of the average particle diameter. The composition includes a liquid carrier comprising up to about 9% alcohol and an amine hydroxide in the amount of about 0.2 to about 9% by weight. The pH of the composition is in the range of about 9 to about 11.5, and the remainder of the solution is water. The composition has low amounts of metal ions, and the composition is used for thinning, polishing and planarizing interlayer dielectric thin films, shallow trench isolation structures, and isolation of gate structures. The invention also comprises methods for using the planarization composition in the manufacture of semiconductor devices.

A device and method for performing electrolyte assisted tissue ablation of metaplasia in the esophagus includes a shaft with an expandable barrier which is deployable from the shaft's distal end. Also included in the device are an electrode and a temperature/impedance sensor which are each mounted on the shaft. Alternatively, the shaft may be a catheter formed with several lumens which are used independently for housing optical elements and for transferring fluid. In the operation of the device, the distal end of the shaft or catheter is placed in the esophagus proximal the cardia. The barrier is then deployed to the cardia and expanded to seal the esophagus from the stomach. The esophageal volume between the barrier and the catheter is partially flooded with a conducting medium and an electrode is deployed into the conducting medium. The sensor is also deployed into contact with the tissue to be ablated. Using open-loop control, or using temperature, impedance, or visual monitoring for closed-loop control, the metaplasia is ablated by passing radio frequency energy from the electrode and through the conducting medium for contact with the tissue being ablated.
摘要:
A method and system for providing Doppler data that is corrected for misalignment between the flow direction within a vessel and the beam orientation of the ultrasound probe. A conventional ultrasonic Doppler color mapping system is adapted to include a system to measure and record the free space position and orientation of the ultrasonic probe, as well as a system to generate and record the experiment time. A set of 2D image planes is acquired, each plane labelled with time, position, and orientation data. A structural representation according to the acquired data is used to determine the flow direction for the imaged vessel structure. Based on this identified flow direction, and the orientation and position information for each acquired 2D slice, the 2D Doppler signals are appropriately transformed into corrected velocity values. These corrected velocity values may then be used to construct a 3D flow field as a function of time.
