Abstract: Robotic systems for orthopedic surgery are provided. The robotic systems may include at least first and second motors coupled to each other. An output shaft of one of the motors may be connectable to a surgical tool guide. An output shaft of another of the motors may be coupled to a portion of a ball and socket joint. A corresponding portion of the ball and socket joint may be coupled to a bone mount which may be attached to a bone to mount the first and second motors to bone for performing orthopedic surgical procedures.

Abstract: The present embodiments provide a pointing device and method for using the pointing device to manipulate data on a display screen of a computing device. Components of the pointing device may include one or more sensors to detect at least one hand movement acting upon the mouse and one or more controllers to translate the at least one hand movement into a mouse action. Components of the pointing device may also include a transmitter to transmit the mouse action to a computing device, and a mouse housing comprising a soft, pliable material, wherein the one or more, the one or more controllers, and the transmitter are embedded within the soft, pliable material.

Abstract: A device which monitors the head turn movement of a golfer during a golf swing. It gives the golfer instantaneous feedback by informing him whether his head turned prior to or after the golf club struck the ball. This feedback is done in the form of a digital LCD display of the time difference in milliseconds and also in the form of audible beeps. From this information, the golfer can make the necessary adjustments and corrections in the execution of his swing. The device is compact and portable. It is placed near the golf ball such that the ball lies directly between the golfer and the device. After the information is displayed, the device automatically resets and readies itself to monitor the next golf swing.
