The present disclosure is directed to electrosurgical pencils having variable controls. In one aspect, the electrosurgical pencil, includes an elongated housing, an electrocautery blade supported within the housing and extending distally from the housing, the electrocautery blade being connected to a source of electrosurgical energy, an activation button supported on the housing, the activation button being movable from a first position to at least a subsequent position, and a transducer electrically connected between the activation button and the source of electrosurgical energy. The transducer is configured to transmit an electrical output signal to the electrosurgical energy source correlating to the movement of the activation button. The source of electrosurgical energy correspondingly supplies an amount of electrosurgical energy to the electrocautery blade dependant upon the electrical output signal.

Provided are a method, system, and program for reassigning storage volumes from a failed processing system to a surviving processing system. A first processing system detects a failure of a second processing system. The first processing system determines device groups of storage devices managed by the failed second processing system and determines for each determined device group, hosts that connect to storage devices in the device group. The first processing system sends, for each device group, a unit check to each determined host indicating failure of each device group through one storage device in the device group to which the determined host connects. The determined hosts execute instructions to terminate any I/O operations in progress on the storage devices in the device group in response to the unit check indicating failure of one storage device in the device group and issue, a command to one storage device for the device group to end the busy condition.

A process and apparatus for producing compressed, gas-stabilized tampons are disclosed. The gas-stabilized tampons include tampons having preferably multiple folds for improved leakage protection and comfort through improved expansion characteristics. The number of folds can vary from 3 to 20 and greater. The process includes the step of forcing a gas through the compressed tampon. The gas can include steam.

Provided are a method, system, and article of manufacture for removing alias addresses from an alias address pool. A plurality of alias addresses are assigned to an alias address pool, wherein the alias addresses in the alias address pool are capable of being dynamically assigned to a device to service I/O requests to the device. An operation is initiated by a process to remove a specified alias address from the alias address pool. An indicator is set to prevent additional processes from removing one alias address from the alias address pool in response to initiating the operation. The specified alias address is removed from the alias address pool.

An electrosurgical pencil is provided which includes an elongated housing, an electrocautery blade supported within the housing and extending distally from the housing. The electrocautery blade is connected to a source of electrosurgical energy. The pencil also includes at least one activation switch supported on the housing which is configured and adapted to complete a control loop extending from the source of electrosurgical energy. At least one voltage divider network is also supported on the housing and is electrically connected to the source of electrosurgical energy.

Shaped, contoured crushable structural members and methods for making the same are described. The contoured structural members comprise composite or metal materials sandwiching a support or stabilizing structure. The structural members are made crushable by incorporating an initiator into the structural members. The structural member crushes at the location of the initiator by absorbing the energy of an exerting load. The shaped structure is provided by bending the generally straight shape of the structural member. With a shaped, contoured, crushable, and generally non-flat structure, applications and uses for the structural members of the present invention are nearly limitless.

A uniquely designed torque wrench having a torque body, the torque body attached to a drive head, with the head having an opening through its center, for fitting over a nut, such as a multi-sided jam nut positioned on a compresor shaft. The drive head further provides a portion which can be disengaged and opened, to define a gate which can allow the jam nut to be positioned within the opening, and the gate portion resecured, to define the head secured around the jam nut. There is further provided a hydraulic cylinder secured between the wrench body and the head so that under hydraulic pressure, the head is rotated which in turn imparts sufficient rotation to the jam nut under sufficient pressure to torque up the nut to the desired foot pounds required. Another embodiment includes an adaptor insertable into the opening of the torque wrench for accommodating a certain jam nut configuration, so that the tool can be used on the varied types of jam nut designs.

A bipolar electrosurgical instrument has opposable seal surfaces on its jaws for grasping and sealing vessels and vascular tissue. Inner and outer instrument members allow arcuate motion of the seal surfaces. An open lockbox provides a pivot with lateral support to maintain alignment of the lateral surfaces. Ratchets on the instrument members hold a constant closure force on the tissue during the seal process. A shank portion on each member is tuned to provide an appropriate spring force to hold the seal surfaces together. During surgery, the instrument can be used to grasp and clamp vascular tissue and apply bipolar electrosurgical current through the clamped tissue. In one embodiment, the seal surfaces are partially insulated to prevent a short circuit when the instrument jaws are closed together. In another embodiment, the seal surfaces are removably mounted on the jaws.
