Abstract: A sense head comprises a plurality of coils and a needle window. The sense head is operable to receive RF signals communicated from a needle target such as an injection port located within a patient. A user interface is configured to visually display an indication to a user relating to the positioning and orientation of the sense head relative to the needle target. The positioning and orientation may be determined based on RF signals received by the coils in the sense head. With the sense head positioned based on information provided through the visual display, the user may insert a needle through the needle window to reach the needle target. The sense head may also receive communications relating to the pressure of fluid in an implanted device. The user interface may further display information relating to the fluid pressure in the implanted device.

Granted: 2013-09-10
Abstract: The present invention relates to a device for the distraction of the spinous processes of two adjacent vertebrae. The spinous processes of the two vertebrae are supported on two separated distraction means being attached to a central body which can be expanded in an infinitely variable manner. The central body can be moved apart in an infinitely variable manner and be fixated along at least one guiding means. By moving apart the central body, the distraction means are expanded along the axial axis and thus distract the spinous processes of the two vertebrae supported on them.  Furthermore, holding means can provide for a stable positioning of the implant and prevent an unwanted movement of the device after the implantation.

Title: Use of the dynamic downhole measurements as lithology indicators
Inventor: JOGI PUSHKAR NATH
IPC: E21B49/00
Filed: 2006-02-17
Granted: 2012-05-15
Abstract: A drilling system provides indications of the lithology of the formation being drilled by dynamically measuring at least one parameter of interest that is affected by the lithology of the formation being drilled. Suitably positioned sensors make dynamic measurements of parameters such as downhole weight on bit, bit torque, bit revolutions, rate of penetration and bit axial acceleration. One or more processors use the sensor measurements in conjunction with predetermined lithological models to determine whether the measurements indicate a change in formation lithology. Suitable models can be on derived expressions such as rock drillability, drilling response, dynamic drilling response, normalized or dimensionless torque; and formation shear strength. The lithological indications provided by the processor can be used to adjust drilling parameters, steer the BHA, monitor BHA health, and provide depth locations for bed boundaries and formation interfaces.
