  • Patent number: 8497694
    Abstract: An on-chip sensor measures dynamic power supply noise, such as voltage droop, on a semiconductor chip. In-situ logic is employed, which is sensitive to noise present on the power supply of functional logic of the chip. Exemplary functional logic includes a microprocessor, adder, and/or other functional logic of the chip. The in-situ logic performs some operation, and the amount of time required for performing that operation (i.e., the operational delay) is sensitive to noise present on the power supply. Thus, by evaluating the operational delay of the in-situ logic, the amount of noise present on the power supply can be measured.

  • Publication number: 20080000955
    Abstract: A filler tray and a unitary blank for assembling the filler tray are provided. The filler tray generally includes a bottom filler, a back filler, and two side fillers that assemble together to define an opened top enclosure adapted to contain one or more high cost product packages. The products contained in the filler tray are accessible from the open top enclosure. The filler trays may be palletized in standard configuration and may be assembled from the unitary blank cut from a single sheet of corrugated fiberboard.

  • Publication number: 20070260227
    Abstract: An axial load limiting system can include a handle having a lever pivotably connected to the handle, a hollow shaft slidably attached to the handle, and a rod operably connected on the proximal end to the lever and movable axially inside the shaft. A surgical implement, for example, a curette, can be connected to the distal end of the rod and pivotably connected to the distal end of the shaft. The system can include a biasing mechanism adapted to be compressed within a cavity in the handle by an axial load in excess of a predetermined axial load. When pivoting of the surgical implement is restricted due to an obstruction, such as hard tissue, and the excessive axial load is placed on the rod, the rod and the surgical implement can move the shaft in the distal direction so as to compress the biasing mechanism, thereby relieving the rod and surgical implement of the excessive axial load.

  • Publication number: 20070256527
    Abstract: A surgical device can include a torque limiting device or system. The surgical device can include a rod attached on one end to a rotatable handle and attached on the opposite end to a surgical implement. A first torque limiting element can be connected to the handle, and a second torque limiting element can be operably connected to the rod and surgical implement and releasably engageable with the first torque limiting element. When the first and second torque limiting elements are engaged, rotation of the handle can cause rotation of the rod and surgical implement. When a rotational force that exceeds a predetermined torque limit is applied to the handle, the first torque limiting element can disengage from the second torque limiting element, so that the handle is rotatable without rotation of the rod and surgical implement. The first and second torque limiting elements can be re-engageable so that further rotation of the handle can cause rotation of the rod and surgical implement.

  • Publication number: 20070260257
    Abstract: A surgical device, kit, and/or method for interchanging components of the surgical device can include a handle, a docking assembly, a shaft assembly, a coupler assembly, and a surgical implement. The handle can have a lever pivotably connected to the handle, and the docking assembly secured to the handle. The docking assembly can include a docking rod operably attached to the lever and axially slidable within the docking assembly. The shaft assembly can include a shaft rod axially slidable within a detachable shaft and removably attachable to the docking rod. The coupler assembly can be adapted to releasably secure the shaft assembly to the docking assembly. The surgical implement can be attached to a distal end of the shaft rod operable with the lever. The shaft assembly and surgical implement may be interchanged on the handle with other shaft assemblies and surgical implements.

  • Publication number: 20070225807
    Abstract: An apparatus includes an elongate member configured to engage a spinal implant and a locking member. The locking member is disposed at a distal end portion of the elongate member. The locking member is configured to move relative to the elongate member between a first position and a second position in a direction substantially perpendicular to a center line of the elongate member. The locking member is configured to allow the distal end portion of the elongate member to move relative to the spinal implant when in the first position. The locking member is configured to couple the distal end portion of the elongate member to the spinal implant when in the second position.

  • Publication number: 20070068329
    Abstract: A method and apparatus for creating or enlarging a cavity in a patient's body are provided. One implementation of the apparatus includes a head, a pushrod and a handle. The head is rotatable about a first axis and is configured to effectuate a medical procedure. The pushrod is attached at a distal end to the head and attached at a proximal end to a handle. The pushrod is configured to translate along a second axis substantially perpendicular to the first axis, where translation of the pushrod along the second axis rotates the head about the first axis. The handle includes a lever coupled at one first end to the pushrod and pivoting the lever about the third axis translates the pushrod along the second axis.

  • Publication number: 20070006692
    Abstract: Torque limiting devices, tools comprising torque limiting devices and methods for using torque limiting devices are disclosed. In an embodiment, a torque limiting device comprises a first and a second surface disposed in substantially adjacent parallel planar relationship such that within a predetermined torque range the first and second surface rotate together such than a torque applied to the first surface is translated to the second surface. When the torque applied exceeds a certain critical torque, the first and second surfaces slip and therefore the excessive torque is not transferred.
