The invention relates to an artificial intervertebral disc for placement between adjacent vertebrae. The artificial intervertebral disc is preferably designed to restore disc height and natural disc curvature, allow for a natural range of motion, absorb shock and provide resistance to motion and axial compression. Furthermore, the intervertebral disc may be used in the cervical, the thoracic, or the lumbar regions of the spine. The artificial intervertebral disc may include either singularly or in combination: an interior including at least one spring member preferably incorporating a arcuate surface member, a flexible core, the flexible core preferably being a slotted core, a ring spring, a winged leaf spring, or a leaf spring, or The articulating member preferably being attached to one of the endplate by an intermediate shock absorbing element.

A system providing methods enabling data in Extensible Markup Language ("XML") format to be extracted, transformed and stored in a database, file system or main memory is described. The extraction and transformation process is generalized and can be used on various types of XML data, enabling XML data to be stored and queried using standard database query methodologies. The system includes parse-time functionality to transform XML documents into a structure having an interface that enables efficient access to the underlying data. The system also includes query execution-time functionality providing greater efficiency by bringing only the relevant portions of transformed XML data into memory in response to a query. The system parses and translates queries into a structure that can be executed without the need to write custom application-specific navigation code to search XML data. The system also enables original XML documents (or portions thereof) to be recomposed when required.

A method and apparatus for providing force feedback to a user operating a human / computer interface device in conjunction with a graphical user interface (GUI) displayed by a host computer system. A physical object, such as a joystick or a mouse, controls a graphical object, such as a cursor, within the GUI. The GUI allows the user to interface with operating system functions implemented by the computer system. A signal is output from the host computer to the interface device to apply a force sensation to the physical object using one or more actuators. This desired force sensation is associated with at least one of the graphical objects and operating system functions of the graphical user interface and is determined by a location of the cursor in the GUI with respect to targets that are associated with the graphical objects. The graphical objects include icons, windows, pull-down menus and menu items, scroll bars (“sliders”), and buttons. The force sensation assists the user to select a desired operating system function or physically informs the user of the graphical objects encountered by the cursor within the GUI. A microprocessor local to the interface apparatus and separate from the host computer can be used to control forces on the physical object.

Apparatus for mediating between a cellular telephony network and a wireless LAN, comprises a first adaptor for allowing signal exchange with the cellular telephony network, a second adaptor for allowing signal exchange with the wireless LAN; and a presence tracker associated with the adaptors for obtaining and storing a current location of a wireless device on any of the networks. The apparatus allows for mobile wireless devices to connect to wireless LANs and be able to register and receive services from their mobile operator, by treating the LAN in the same way as a foreign network in International roaming.

It is an object of the present invention to provide a rechargeable handheld injection device that supports stock syringes for purposes of injection / removal of fluid or fat cells. This injection device comprising a housing, an adjustable / replaceable syringe cradle assembly, an electrical actuator with settings of dual speed that actuate the syringe cradle assembly in forward and reversible drive using forward and reverse buttons, a trigger switch to control the actuator, a pre-programmed syringe control panel, a needle guard assembly and a rechargeable battery in conjunction with ON / OFF switch button and electronic component. A separate wall mount battery charger is used to charge the battery of this handheld device.

In an endoprosthesis (11h) for a joint, the two interacting joint parts (15h, 16h) are joined by a cord-type connection piece (21h), which is attached in the vicinity of the body axis (M2h, M2h') of the convex condyle (15h) and extends through a longitudinal groove (22h) in the flexion direction of the joint. The connection piece assures a play space (31h) between the contact surfaces (19h, h', 20h, h') of joint (11h). It is protected from friction on groove wall (55h, 55h') by an elevation (50h, 43h) in concave joint part (16h). An elevation (43h, 50h) at concave joint part (16h) and a depression (49h) at convex joint part (15h) interact in such a way that the lateral movement play space between depression and elevation determines the freedom of movement with respect to the lateroflexion of the joint. In preferred forms of embodiment, thanks to the spherical surfaces at least one pair of corresponding sliding surfaces (19h, 20h; 20h') on the two condyles lie flatly on one another, under load, in any position of the joint.

The present invention provides a GFCI that not only has ground fault protection, but also is capable of providing reverse wiring protection as well as detection of end of the service life of the GFCI by way of utilizing an end of life detection control circuit in connection with the reset button. In addition, the GFCI of the present invention provides a forcible mechanical tripping assembly by way of utilizing the test button. Finally, the present invention provides method for detecting whether the service life of the GFCI has ended.
