Title: Detection of inconsistencies between a reference and a multi format soundtrack
Inventor: FURLAN ROBERTO
IPC: G10L25/69
Filed: 2004-09-15
Abstract: Automatic detection of errors among different formatted sound tracks of the same language on a motion picture film stock (14) can be achieved by first acquiring successive audio segments from each of the sound tracks. During a time window of prescribed duration, the audio of each different formatted track undergoes analysis to yield a numeric value. The successive analysis of the audio continues until no further audio exists for analysis. The resultant collection of numeric values undergoes formatting into a numeric file for comparison against a reference file representing audio obtained from a particular source, such as originally recorded material, a sound print, or a duplicated copy of a sound film. If the difference between a formatted numerical file and the reference file exceeds a threshold value, then an error exists in that formatted sound track, and an operator can take appropriate action.

Title: Orthopaedic implant with sensors
Inventor: HALL HARRY T IV
IPC: A61F2/44
Filed: 2005-06-07
Abstract: The present invention relates to an orthopaedic implant, such as a bone plate, for the fixation of bone where the implant also has at least one microchip and at least one sensor connected to the microchip. The sensor or sensors are configured to receive physical stimulus from a portion of the implant or the patient's tissue such as temperature, pressure, and strain. The information received from the sensor or sensors is gathered by the microchip and transmitted to a receiver, such as a personal computer, outside the patient.  This information enables doctors to diagnose the useful life of the implant, the load sharing of the bone plate, and possible complications typically associated with orthopaedic implants such as infection, fracture non-union, and fatigue. The implant may also have one or more electrodes located on its surface which emit an electric current to stimulate healing of the broken or fractured bone.

Title: Activated aluminum/depolymerized zirconium antiperspirant compositions
Inventor: LI ZIJUN
IPC: A61K8/26
Filed: 2004-10-22
Abstract: An aluminum-zirconium antiperspirant composition comprising activated aluminum and depolymerized zirconium species is characterized by an Inductively Coupled Plasma (ICO)-Size Exclusion Chromatograpy (SEC)-HPLC method. A good correlation is obtained between the intensity of the zirconium peak at retention time of about 4.3 minutes to about 4.9 minutes by ICP-SEC-HPLC and the extent of the polymerization of the zirconium species, such that the higher the intensity of the zirconium species, the greater the polymerization of the zirconium species. The extent of the polymerization of zirconium species in the activated aluminum-zirconium salt is affected by the factors and reaction conditions such as the ratio of chloride to zirconium in a zirconium hydroxy chloride (ZHC) solution; the heat treatment of the ZHC  glycinate solution; and the concentration of activated basic aluminum chloride (BAC) solution. Controlling the reaction conditions yields a novel aluminum-zirconium antiperspirant salt of enhanced efficacy having activated aluminum and depolymerized zirconium species.
