| 20090024134 | SURGICAL MEASUREMENT AND RESECTION FRAMEWORK - A frame is attachable to first and second bone portions of a patient to facilitate measurement and resection of one or more bony landmarks. The frame has two anchoring features, each of which has a semispherical surface that permits rotational adjustment of the frame against the bone portions until the frame is secured. A bridging structure couples the anchoring features together such that the anchoring features are lockably movable with respect to each other. The bridging structure may have three linear sliders that provide the relative motion. A locking mechanism exerts pressure on all three sliders to lock them in place. An external anchoring feature enables attachment of the frame to a stationary reference to stabilize the frame. The frame also has registration features that permit attachment of measurement or resection tools to the frame. The frame is particularly useful for measuring and resecting spinal facets for facet replacement. | 01-22-2009 |
| 20090099607 | Apparatus and method for dynamic vertebral stabilization - A posterior vertebral stabilizer has a resilient member such as a linear spring, which operates in tension and compression. The resilient member may be kept straight by a stabilization rod extending through the spring, or by a telescoping assembly that encases the resilient member. The ends of the stabilizer are attachable to pedicles of adjacent vertebrae so that the stabilizer adds stiffness to control flexion and extension of the vertebrae. Two such stabilizers may be used, and may be connected together by a crosslink designed to limit relative rotation of the stabilizers. Thus, the stabilizers may restrict axial rotation and lateral bending between the vertebrae, while permitting stiffened flexion and extension. Such stabilizers help provide the stiffness of a healthy intervertebral disc. In the event that fusion of the joint becomes necessary, a set screw or other component may be used to further restrict flexion and extension. | 04-16-2009 |

| 20100204798 | SYSTEM AND METHOD FOR FUSION CAGE IMPLANTATION - A system and method facilitate insertion of a fusion implant into the intervertebral space of a spine. The fusion implant may have a first bone engaging surface and a second bone engaging surface. An attachment interface on an insertion tool allows the implant to be releasably secured to the insertion tool, so that the insertion tool may be detached from the implant without requiring a threaded coupling. The implant may be positioned in two different orientations with respect to the insertion tool to permit usage of two different techniques to insert the implant into the intervertebral space. A recessed support member in the implant creates gaps between bone facing surfaces and the vertebral bodies such that bone graft material may occupy the gaps. The implant includes embedded radiographic markers which facilitate radiographic detection of the orientation of the implant through the surrounding tissue. | 08-12-2010 |

| 20080201898 | SELF-CLEANING FILTER ARRANGEMENT WITH ACTIVATION SIGNAL FOR FLOOR CARE APPARATUS - A floor care apparatus has a filter with an intake and out take. A first pressure sensor is arranged on the intake while a second pressure sensor is arranged on the out take. A controller connects to the sensors to receive signals indicative of relative pressure. Whenever a predetermined pressure differential between the signals is achieved, an undesirable load on the filter is deemed occurred and initiation of a self-cleaning of the filter begins. In this manner, filter cleaning only occurs on an as-needed basis and user intervention is avoided, thereby adding convenience. The controller is also able to ascertain a clogged airway condition. Various features contemplate pressure sensor signals arranged to scale suction as positive pressures, meeting the predetermined pressure differential at other than a maximum pressure differential between the first and second pressure sensors, and scaling the predetermined pressure differential relative to the maximum pressure differential. | 08-28-2008 |
| 20090020141 | FLOOR CARE APPARATUS WITH PHOTOELECTRIC QUASI-AUTOMATIC HEIGHT ADJUSTMENT - A floor care apparatus includes a nozzle assembly having suction inlet. A canister assembly is connected to the nozzle assembly. A suction generator and a dirt collection vessel are carried on one of the nozzle assembly and canister assembly. A height adjustment mechanism is carried on the nozzle assembly. In addition a photo sensor unit is carried on the nozzle assembly for sensing the height of the nap of an underlying carpet or rug being cleaned. The height adjustment mechanism and the photo sensor unit cooperate together to allow the operator to automatically adjust the operating height of the vacuum cleaner relative to the height of the nap of the carpet being cleaned. | 01-22-2009 |
| 20090126146 | VACUUM CLEANER WITH HEAT SINK IN AIR PATH - A floor care appliance includes a nozzle assembly having a suction inlet, a canister assembly, a dirt collection vessel carried on the canister assembly, a suction generator carried on the canister assembly and a wand assembly connecting the nozzle assembly with the canister assembly. The wand assembly includes an inlet connected to the nozzle assembly, an outlet connected to the canister assembly and a conduit defining an air path between the inlet and the outlet. A heat sink carried on the wand assembly is provided in communication with the air path in the conduit. An electronic control is connected to the heat sink. | 05-21-2009 |
| 20090241284 | FLOOR CARE APPLIANCE EQUIPPED WITH BREAK-OVER PROTECTED LATCH ASSEMBLY - A floor care appliance includes a housing having a nozzle assembly with a suction inlet. A dirt collection vessel and a suction generator are carried on the housing.
