Title: Methods and apparatus for minimizing backlash in a planetary gear mechanism
Inventor: LUMPKIN TED
IPC: F16H55/18
Filed: 2005-03-11
Abstract: A planetary gear system (10) includes a planetary gear assembly (14) having a first planetary gear (28), a second planetary gear (32) rotatable relative to the first planetary gear, and a torquing mechanism (16). The torquing mechanism generates a torsional spring force of the planetary gear assembly to cause the first planetary gear to rotate along a first direction and the second planetary gear to rotate along a second direction, opposite to the first direction. As a result, the teeth of the first planetary gear contact teeth of a corresponding first stationary ring gear (18-1) and the teeth of the second planetary gear contact teeth of a corresponding second stationary ring gear (18-2) . The torquing mechanism, along with the configuration of the planetary gear assembly, minimizes or eliminates the presence of gaps between the contacting teeth of the planetary assembly and the stationary gear rings (18) and minimizes backlash within the planetary gear system.

Title: Pre-chamber spark plug
Inventor: TOZZI LUIGI P
IPC: H01T13/54
Filed: 2005-06-07
Abstract: A method and apparatus to maximize spark plug life in pre-chamber spark plugs operating with ultra-lean mixtures and/or elevated engine BMEP is presented.  Electrode erosion is reduced by spreading discharge energy over a wider surface area, maintaining fuel concentration in the spark gap, controlling gas static pressure during discharge, and maintaining safe electrode temperature.  Energy is spread via a swirling effect created by periphery holes in an end cap, resulting in a lower specific energy discharge at the electrodes.  Divergently configured electrodes reduce the spark voltage at high operating pressures and the energy required for ignition. The flow field generated at the electrodes prevents electrical shorts due to water condensation and avoids misfire. The center electrode insulation provides an effective heat transfer path to prevent electrode overheating and preignition. The volume behind the electrodes provides a volume for burnt products from previous combustion cycles and leads to more reliable igntion.

Title: Tone synthesis apparatus and method
Inventor: UMEYAMA YASUYUKI
IPC: G10H7/00
Filed: 2007-01-09
Abstract: In a storage section, there are stored special connecting waveform data for connecting between at least two notes to be generated in succession. The special connecting waveform data contain only a waveform of a succeeding-note region of a waveform connecting portion which is provided for a continuous transition between the at least two notes and which is divided into a preceding-note region and the succeeding-note region. When a connecting tone is to be generated for connecting between two notes in accordance with acquired performance information, a tone waveform connecting between waveforms of the two notes is generated using the special connecting waveform data. With such arrangements, the waveform data of the succeeding-note region are read out without waveform data of the preceding-note region being read out, so that it is possible to reduce a time required for transition from a preceding note to a succeeding note. Thus, in the connecting portion for continuously connecting between tones with no break therebetween, a tone can be synthesized with high quality without involving a tone generating delay in the succeeding note.

Title: Personalized headphone virtualization
Inventor: SMYTH STEPHEN MALCOLM
IPC: H04S1/00
Filed: 2005-09-01
Abstract: A listener can experience the sound of virtual loudspeakers over headphones with a level of realism that is difficult to distinguish from the real loudspeaker experience. Sets of personalized room impulse responses (PRIRs) are acquired for the loudspeaker sound sources over a limited number of listener head positions. The PRIRs are then used to transform an audio signal for the loudspeakers into a virtualized output for the headphones. Basing the transformation on the listener's head position, the system can adjust the transformation so that the virtual loudspeakers appear not to move as the listener moves the head.
