A femoral component of a knee prosthesis has spaced condyle surfaces defining a notch therebetween. The notch defines an elongated cam housing having an anterior cam and a posterior cam at opposite ends of the housing. The tibial component of the knee prosthesis includes a platform and a bearing supported on the platform, the bearing defining bearing surfaces configured to articulate with the condyle surfaces. The tibial component includes a spine projecting superiorly from the bearing that defines an anterior face and a posterior face. The posterior face and the posterior cam define complementary curved surfaces configured for cooperative engagement when the femoral component and the tibial component are at a predetermined flexion angle. The cam housing is configured to form a gap between the posterior cam and the spine when the knee is normally extended. In another feature, the spine includes a stiffening pin extending therethrough.

A spinal fusion implant of non-bone construction to be introduced into any variety of spinal target sites. The spinal fusion implant of the present invention includes a top surface, a bottom surface, first and second lateral sides, a proximal (posterior) end and a distal (anterior) end. The spinal fusion implant of the present invention may be used to provide temporary or permanent fixation within an orthopedic target site. To do so, the spinal fusion implant may be introduced into a disc space while locked to a surgical insertion instrument and thereafter employed in the proper orientation and released. Once deposited in the disc space, the spinal fusion implant of the present invention effects spinal fusion over time as the natural healing process integrates and binds the implant.

A hand held orbital sander has a housing having an electronically commutated motor disposed therein and an orbit mechanism disposed beneath the housing. A motor controller is coupled to the motor. The motor controller changes the speed of at which it runs the motor from an idle speed to a sanding speed upon the motor speed dropping from idle speed to an idle speed threshold value and changes the speed at which it runs the motor from sanding speed to idle speed upon the motor speed increasing from sanding speed to a sanding speed threshold value. The sander may have a mechanical brake that brakes the orbit mechanism and the motor controller also dynamically brakes the motor.

An improved treatment of obstructive sleep apnea is disclosed. A method and various device combinations are presented. The device combinations describe optimal adjustments to properly position a nasal pillow in each of a patient's nares. A novel swivel joint is described to which a nasal pillow is slip-fit over. The swivel joint prevents loss of a proper seal between the nasal pillow and nare which may otherwise occur as a result of head movement. Also presented is an improved obturator mouthpiece design which substantially eliminates air flow through the oral cavity resulting from leakage in the oropharynx.

A power tool is a “low profile” power tool, that is the overall height of the power tool is sufficiently small that a user can grasp the top of the power tool with the user's hand and the hand will be positioned relative close to the bottom of the power tool compared with existing power tools. The low profile power tool uses a low profile motor having a diameter to lamination height ratio of at least 2:1. In an aspect of the invention, the motor is an electronically commutated “pancake” style motor. In an aspect of the invention, the power tool is a random orbital sander or an orbital sander having a motor that provides at least 40 watts of power. In an aspect of the invention, the sander has a mechanical brake that brakes the orbital mechanism and the motor is dynamically braked.

An end assembly seals a cylindrical electrochemical cell. The assembly includes a positive temperature coefficient (PTC) device and a gasket having a protrusion that cooperates with the end assembly isolates the PTC device from primary axial compression forces present in the closure assembly. In further embodiments of the present invention, the end assembly may be produced by insert molding a seal element about the terminal cover and the gasket itself has an E or F shaped cross section.

An operator's seat (6) is mounted via a posture adjusting mechanism (40) on a supporting plate (3) supported by at least two damper cylinders (50, 30) at a place where an operator's seat is installed, and at least one of the damper cylinders (50, 30) is used as a damper cylinder (50) for reducing vibrations by making use of a magnetic rheological fluid.

The present invention provides a sectional crimped graft that allows graft flexibility where required and limits the overall longitudinal extension. The present invention overcomes the disadvantage of fully crimped grafts by controlling the number of crimps per unit length, crimp height, crimp geometry and their location along the graft wall, dependent on the particular end-use application. In so doing, flexibility and elongation can be controllably tailored only in areas where significant anatomical angulation is present. It may also be useful in applications other than stent grafts such as surgical grafts for aortic and peripheral areas. Limiting the overall graft longitudinal extension also facilitates the deployment of the stent-graft into the blood vessel.

A method and system for high-speed, high-resolution, 3-D imaging of an object including an anamorphic magnification and field lens system to deliver the light reflected from the object to a small area position detector having a position-sensing direction. Preferably, an acousto-optic deflector together with associated lens elements scans a beam of modulated laser light across the object to produce a telecentric, flat field scan. The deflector has a feedback loop to enable uniform illumination of the object. The light scattered from the object is collected by a telecentric receiver lens. A combined spatial and polarization filtering plane preferably in the form of a programmable mask is provided to control the polarization and acceptance angles of the collected light. A reduction or focusing lens is positioned immediately behind the filtering plane and is utilized as a telescope objective. The lens system includes a negative cylinder lens having a relatively large focal length and a field lens having a relatively small focal length. The cylinder lens and the reduction lens magnify the image in the position sensing direction of the detector and the field lens delivers the magnified light to the detector. The detector is a photodetector such as a lateral effect photodiode or a rectangular lateral effect detector. A pre-amplifier provides a pair of electrical signals which are utilized by signal processing circuitry to compute the centroid of the light spot.

A control mechanism for a powered running board on an automotive vehicle, such as a sport utility vehicle, utilizes the memory function of the vehicle to store therein established operating positions for the running board. The user or occupant of the vehicle can manually position the powered running board to a convenient operating position within a range of available operating positions on the vehicle. By storing the selected position of the running board in the memory function of the vehicle, the control mechanism can return to that same operating height each time the occupant seeks to use the running board for entry or exit of the vehicle. The control mechanism is operable with different configurations of running boards and with different power devices for effecting the movement of the running board.
