  • Hard metal insert for a drill bit for percussion drilling and method for grinding a hard metal insert
    Patent number: 9290999
    Abstract: A hard metal insert for a drill bit for percussion drilling. A wear part includes a cap including a wear surface. A mount includes a cylindrical part having a cross-sectional area and a diameter. The cap includes a front part with an extension along an axis of symmetry of the insert from a first point on the wear surface to a second point in the cap. The front part includes a volume between a first plane intersecting the axis at the first point and a second plane intersecting the axis at the second point. The volume is ?0.6 times a cross-sectional area of the front part in the second plane times a distance along the axis between the first and second points. A diameter of the front part in the second plane is ?0.5 times the mount diameter and ?0.6 times the mount diameter.

  • Closed loop brain machine interface
    Patent number: 7209788
    Abstract: A closed loop brain-machine interface is disclosed. The closed loop brain-machine interface translates one or more neural signals into a movement, or a series of movements, performed by a machine. The close-loop brain-machine interface also provides sensory feedback to the subject. Methods of employing the closed loop brain-machine interface are also disclosed.
