20100000422 | Gravity-induced impact nutcracker - A gravity-induced impact-type nutcracker with a self-guided trip hammer that, upon actuation, drops solely via the force of gravity to strike a nut supported within a nut cracking chamber with a consistently guided uniform force. The helve of the hammer is pivotally supported adjacent its rear end between a pair of upstanding guide columns. A cord connected to the rear of the hammer helve is attached to a freewheeling take-up spool which is releasably engagable by a hand crank drive wheel to facilitate raising the hammer head to a set position prior to releasing the same. Continued rotation of the crank causes a release mechanism connected to the rear of the hammer helve to disengage the take-up spool from the drive wheel, thereby releasing and allowing the hammer to drop under its own weight. The cracking chamber which holds the nut includes a removable drawer with a variety of differently sized nut-retaining cavities formed therein for accommodating a variety of different types and sizes of nuts. The impact nutcracker is constructed primarily of wood with an aesthetically pleasing and unique appearance. | 01-07-2010 |

20110071411 | METHOD AND APPARATUS FOR SENSING MECHANICAL ENERGY OF AN IMPLANTABLE LEAD - An apparatus comprises an implantable sensor and a signal analyzer circuit communicatively coupled to the implantable sensor. The implantable sensor is configured for coupling to an implantable lead and the implantable sensor provides an electrical vibration sensor signal representative of mechanical vibration of the implantable lead. The signal analyzer circuit is configured to determine a baseline of the vibration sensor signal, detect a change in the vibration sensor signal from the baseline vibration sensor signal, and provide an indication of the change to a user or process. | 03-24-2011 |
