摘要:
A device adapted to be secured to the foot of a user includes one or more vibration actuators configured to provide vibrations to the user's foot, one or more force or acceleration sensors configured to sense forces or acceleration exerted by the user's foot, and a controller configured to operate the vibration actuators in a continuous mode to provide intermittent vibration to the user's foot independent of information sensed by the force or acceleration sensors. The vibration includes a first period of continuous vibration followed by a second period of no vibration followed by a third period of continuous vibration. The device may also be configured to operate in a feedback mode.

Systems and methods for surgical spinal correction are disclosed. A system including a plurality of bone screws, spinal rods, manipulators, and/or transverse couplers is disclosed for the manipulation of the spinal column is disclosed. A method of achieving, in a single action, manipulation and/or rotation of the spinal column using the disclosed system is disclosed. Also disclosed is a method of conducting spinal surgery to correct spinal deformities wherein spinal rods are pre-bent in a physiological sagittal plane prior to attachment of the vertebrae using bone screws.

A spinal fixation device for securing to a spine includes a body having one or more longitudinal members extending between a pair of wedge members. Each wedge member defines one or more openings therethrough for the reception of a bone screw. The wedge members are disposed on opposite ends of the one or more longitudinal members. One of the wedge members is positionable within a first intervertebral space and the other wedge member is positionable within a second intervertebral space. The one or more longitudinal members define a length that spans one or more vertebrae. The one or more longitudinal members are positionable within the one or more vertebrae when the wedge members are positioned within the respective first and second intervertebral spaces to maintain the body in a minimal profile orientation relative to the spine.

A semi-constrained screw and a cervical plate assembly that engages to a cervical area of the human vertebrae system are disclosed. The semi-constrained screw and cervical plate assembly includes a cervical plate and one or more semi-constrained bone screws. Each semi-constrained bone screw includes an elongated shank, which is mechanically and releasably coupled to a head portion. The head portion includes one or more threaded segments which define one or more slits therebetween. As the semi-constrained bone screw is driven through the screw opening in the cervical plate and into the bone, the head portion allows poly-axial movement of the shank relative to the head portion.

An integrated circuit package comprising an enclosure including a dielectric housing, a first electrical contact, and a second electrical contact. The dielectric housing, the first electrical contact, and the second electrical contact are configured to form a contact side of the enclosure. In addition, the first and second electrical contacts are sized to be substantially alignment insensitive for electro-mechanical connection to corresponding contacts of an end-use equipment. The enclosure encapsulates an integrated circuit die which is electrically coupled to the first and second electrical contacts. The alignment insensitive first and second electrical contacts may be electro-mechanically connected to corresponding contacts of an end-use equipment (e.g., a printer). Further, the integrated circuit package may be hosted by a peripheral device (e.g., a printer cartridge).
摘要:
A piano hammer stopper system includes a stopper rail set comprising at least first and second stopper rail members, each movable between respective first positions allowing unobstructed movement of associated piano hammers and respective second positions stopping at least one associated piano hammer from striking any corresponding string. At least one drive shaft is rotatably coupled to one or both of the stopper rail members. A drive arm is attached to the drive shaft and engages a drive fulcrum. A travel guide directs movement of the first and second stopper rail members between respective first and second positions. Rotation of the drive shaft rotates the drive arm to engage the drive fulcrum for moving one or both of the first and second stopper rail members between respective first and second positions.
摘要:
A rod reducing device includes an elongate member, a pair of jaw members, a sleeve having a cam pin, and an actuation lever. Translation of the cam pin along the inner surfaces of the jaw members pivotally moves the jaw members between a receiving position in which distal end portions of the respective jaw members are widened and an engaging position in which the distal end portions of the respective jaw members are move toward each other to engage the head of the bone screw. The actuation lever is movable between an open in which a distal end portion of the sleeve is disposed proximal of the distal end portions of the jaw members and a closed position in which the distal end portion of the sleeve is disposed distal of the distal end portions of the jaw members for reducing the connecting rod.
摘要:
A bone screw for attaching a bone plate to bone includes a shank defining a lumen extending at least partially therethrough from a proximal end thereof, a head defining a lumen therethrough, and a rod member. The rod member is configured for insertion through the lumen of the head and into the lumen of the shank. The rod member is fixedly engageable with the shank and moveably coupled to the head such that both the rod member and the shank are moveable with respect to the head.
摘要:
A rod reduction device includes a rod reducing member, an anchoring member, and a sleeve. The rod reducing member is configured to engage a spinal rod. The anchoring member is configured to removably attach to a bone anchor. The sleeve defines a longitudinal axis and is operably associated with the rod reducing member and the anchoring member. The sleeve is rotatable with respect to the anchoring member for longitudinally translating the rod reducing member relative to the anchoring member.
摘要:
A VHF energized plasma deposition process wherein a process gas is decomposed in a plasma so as to deposit the thin film material onto a substrate, is carried out at process gas pressures which are in the range of 0.5-2.0 torr, with substrate temperatures that do not exceed 300° C., and substrate-cathode spacings in the range of 10-50 millimeters. Deposition rates are at least 5 angstroms per second. The present method provides for the high speed deposition of semiconductor materials having a quality at least equivalent to materials produced at a much lower deposition rate.
