20080269755 | SYSTEM AND METHOD FOR LOCATING SAW BLADES AND LIKE CUTTING ACCESSORIES WITH A SURGICAL NAVIGATION SYSTEM - A system and method for locating cutting accessories such as saw blades that, when actuated by the complementary driver, move relative to the driver. The saw blade is provided with one or more geometric features. The location of these features is identified by a pointer. The pointer is part of a surgical navigation system used to monitor the position of the driver to which the saw blade is attached. Based on the location of the geometric features, data regarding the head of the saw blade are generated. Thus, the surgical navigation has data indicating the position and orientation of the driver and the position of the head of the cutting accessory relative to the driver. Based on these data, the surgical navigation system generates data indicating the position and orientation of the head of the saw blade or like cutting accessory. | 10-30-2008 |

20140055086 | BATTERY WITH AN INTERNAL MICROCONTROLLER THAT DRAWS DIFFERENT CURRENTS FROM THE CELLS INTERNAL TO THE BATTERY BASED ON THE TEMPERATURE OF THE BATTERY - A rechargable battery with an internal microcontroller, a memory and a temperature sensor. The microcontroller draws a current from the cells internal to the battery used to power device to which the battery is attached. Normally, the microcontroller, is in a first operating mode in which the microcontroller draws a relatively low current. During these periods the temperature sensor generates a signal representative of the temperature of the battery. When the signal from the temperature sensor indicates the battery temperature exceeds a threshold temperature, the microcontroller enters a second operating mode in which the microcontroller draws a relatively high current. While in the second operating mode the microcontroller records in the memory data regarding the fact that the battery temperature exceeded the reference temperature and the amount of time the battery was at a temperature above the reference temperature. | 02-27-2014 |
