New and Improved methods and apparatus for robotic path planning, selection, and visualization are described A path spline visually represents the current trajectory of the robot through a three dimensional space such as a room By altering a graphical representation of the trajectory—the path spline—an operator can visualize the path the robot will take, and is freed from real-time control of the robot Control of the robot is accomplished by periodically updating the path spline such that the newly updated spline represents the new desired path for the robot Also a sensor that may be located on the robot senses the presence of boundaries (obstacles) in the current environment and generates a path that circumnavigates the boundaries while still maintaining motion in the general direction selected by the operator The mathematical form of the path that circumnavigates the boundaries may be a spline

Methods and apparatus for connecting to a bone, which avoid the use of bone screws. A triangular shaped modular implant is used, with two sides of the structure and their respective vertex secured generally within the bone, with the base of the triangle outside the bone. These two arms, whether straight or arcuate, are cannulated, and are held together at their distal ends by a tightened cable that runs through both of the arms. The proximal ends of these arms are connected to a base side that completes the triangular structure. The device may be inserted into a vertebra and the base used for vertebral fusion. Alternatively, the arms themselves may be used to stabilize and fixate adjacent vertebrae, by insertion through adjacent vertebrae trans-segmentally. In the latter case, the vertex may be within the intervertebral space or within the vertebral body close to the intervertebral space.

Spinal implants are disclosed that can be used for annular repair, facet unloading, disc height preservation, disc decompression, or for sealing a portal through which an intervertebral implant was placed.

A micromachined angle measuring gyroscope using a dual mass architecture measures angular positions rather than angular rates. The invention decouples the effects of drive and sense through the use of a dual mass architecture, and is comprised of a single lumped drive mass, which is structurally coupled to a second lumped slave mass, where the drive mass is electrostatically driven at the first resonant frequency the system using parallel plate electrodes. The slave mass is driven to higher amplitudes than the drive mass. In the presence of rotation, the line of oscillation in both masses precesses, which is easily detectable in the slave mass due to the amplified motion, and is exactly equal to the angle of rotation. The two illustrated embodiments are z-axis realizations of this principle, where the first device uses an inner drive / outer sense architecture and the second uses an outer drive / inner sense architecture.
