Sleeve assembly for spinal stabilization system and methods of use
ActiveUS20060293693A1Easy to installEasy to removeInternal osteosythesisDiagnosticsCouplingEm coupling
The present invention is a one or two-part sleeve assembly for use during minimally invasive spinal stabilization surgery. An outer sleeve is designed to slide over the coupling between a polyaxial screw and an inner sleeve so as to prevent the screw from becoming disengaged from the inner sleeve during surgery. The outer sleeve includes a lower generally cylindrical wall having a slot, and an upper extension having an outwardly protruding manipulation handle attached to it. The slot in the lower section extends the entire length of the cylindrical wall, giving it a generally “C” shaped cross section. This slot corresponds with a similar slot on the inner sleeve for receiving a stabilizing rod to be attached to the polyaxial screw during surgery. The interior diameter of the lower section is approximately the same as the outer diameter of the inner sleeve, so that the outer sleeve may slide snugly over the inner sleeve and the screw coupling. In addition, the edges of the cylindrical wall adjacent to the longitudinal slot are flattened so as to conform to the shape of the inner sleeve and the head portion of the polyaxial screw where it couples with the inner sleeve.

Proximity sensing based on antenna impedance variation
InactiveUS7113087B1Simple and economical mannerReduce and avoid needEnergy efficient ICTDigital data processing detailsElectricityAntenna impedance
Proximity of a user body part can be detected by measuring the effects such proximity has on antenna impedance mismatches. The amount of mismatch affects the amount of RF signal energy reflected back into a transmission line connecting the antenna to a RF signal source. A directional coupler has a main line electrically connected to the transmission line, as well as a coupled line. The directional coupler produces a signal on its coupled line in relation to the magnitude of reflected energy on the transmission line; the amount of reflected energy varies in response to how well the antenna impedance matches the transmission line impedance. A signal detector is electrically connected to the coupled line, and responds to signals produced in the coupled line by the main line. The signal detector output is then used to determine whether a body part is in proximity. Other aspects the invention include an adaptive algorithm to adjust a threshold for proximity determination.

The method and system involve using inductors that are substantially symmetrical about their horizontal and / or their vertical axes and providing current to the inductors in a way so that the resulting magnetic field components tend to cancel each other by virtue of the symmetry. In addition, two such inductors may be placed near each other and oriented in a way so that the induced current in the second inductor due to the magnetic field originating from first inductor is significantly reduced. The inductors may be 8-shaped, four-leaf clover-shaped, single-turn, multi-turn, rotated relative to one another, and / or vertically offset relative to one another.

The resonant circuit is driven by the driving means (6), comprising a control unit (6c) arranged to induce an alternating voltage between a first semiconductor switch (6a) and a second semiconductor switch (6b). At the output of the transformer (9) an alternating voltage is generated, which is rectified to a DC-voltage by a diode rectifier, filtered by an output capacitance. The resonant circuit (5) is operable on its coupling independent point by the driving means (6). This figure schematically illustrates a situation, where a variable coupling between the first inductor winding (3) and the inductor winding (13) exists.

InactiveUS20060044018A1Low powerImprove performanceMultistate logicSolid-state devicesSchottky barrierMulti-level cell
An IC solution utilizing mixed FPGA and MLC arrays is proposed. The process technology is based on the Schottky CMOS devices comprising of CMOS transistors, low barrier Schottky barrier diode (SBD), and multi-level cell (MLC) flash transistors. Circuit architectures are based on the pulsed Schottky CMOS Logic (SCL) gate arrays, wherein a variable threshold NMOS transistor may replace the regular switching transistor. During initialization windows, existing FPGA programming techniques can selectively adjust the VT of the switching transistor, re-configure the intra-connections of the simple SCL gates, complete all global interconnections of various units. Embedded hardware arrays, hardwired blocks, soft macro constructs in one chip, and protocols implementations are parsed. A wide range of circuit applications involving generic IO and logic function generation, ESD and latch up protections, and hot well biasing schemes are presented. The variable threshold transistors thus serve 3 distinctive functions. It acts as an analog device to store directly nonvolatile information in SCL gates. It couples the diode tree logic functions. Finally, it stores and operates large amount of information efficiently. The mixed SCL type FPGA and MLC storages shall emerge as the most compact logic and memory arrays in Si technology. Low power, high performance, and high capacity ICs are designed to mix and replace conventional CMOS-TTL circuits. The idea of multi-value logic composed of binary, ternary, and quaternary hardware and firmware is also introduced.
