Title: Differential with side gears restrained for axial movement by a nut and bolt
Inventor: KRZESICKI RICHARD M
IPC: F16H48/22
Filed: 2004-01-30
Abstract: An independent axle differential comprises a first side 14, a second side 18 each having an abutment face 124 and a passage 126. A bolt 128 passes through the passages 126 and ahead 150 of the bolt 128 engages one of the abutment faces 124. A nut 130 is coupled to the bolt and engages the other abutment face 124, thereby restraining the first and second side gears 14, 18 against axial movement. Bearings 136 and washers 132 mate with the abutment faces 124 and the bolt head 150 and nut 130 so as to facilitate low friction relative rotation between the side gears and nut and bolt. First and second axle output shafts 12, 16 are disposed in cavities 122 and each have a shaft end proximate the nut 130 or the bolt head 150 so as to prevent the nut 130 loosening and walking off the bolt 128. In other embodiments the abutment faces 124 are replaced with thrust washer (164, fig 11) and the nut and bolt may have tapered ends (288, 290, fig 12) to enhance alignment.

Title: Radio microphones and wireless musical instruments with multiplexed digital channel
Inventor: THOMAS HOWARD
IPC: H04R1/08
Filed: 2005-06-08
Abstract: Radio mics and wireless musical instruments digitise the recorded sound and then transmit it over a time multiplexed radio channel. Synchronisation of the channel is by a synch pulse transmitted from the radio receiver. The system may utilise a direct sequence spread spectrum (DSSS) channel for enhanced noise immunity and the sampling and quantisation of the ADC's and DAC's may be adjusted to allow a trade off between sound quality and number of channels. The system overcomes the need for 1 receiver per microphone associated with analogue systems and can eliminate the cabling requirements in recording studio applications.

Title: Automatic material data standardization tool
Inventor: GREEN CAMERON
IPC: G06F17/27
Filed: 2006-01-30
Abstract: This invention relates to the tool which is embodied in a complex but easy-to-use software program aimed at business end-users which accurately and automatically converts material description data from a "disorganized" or "dirty" state to conform to and comply with a defined data standard. The software does this firstly using complex "under the hood" mathematical algorithms to automatically build cleansed descriptions with a certainty-of-match color-coding using the material type and industry specific business content included in the program. Secondly the software leads the user through the manual process of cleansing more challenging data according to a special built-in method. As the software is used, opportunities are given to the business end user to fine tune the algorithms, which means that at end state, the customized software can become the using company's actual detailed data standard (instead of just a word document) through which all future data can be verified. Although the tool is software based, the method integrated into the software, as well as the pre-delivered content, designed to the actual needs of the business end user (and not an information technology specialist) are key in it accurately cleansing/standardizing large numbers of material data quickly.

Title: Method and Apparatus for Extending Useful Range of Air Data Parameter Calculation In Flush Air Data Systems
Inventor: CRONIN DENNIS JAMES
IPC: B64D43/02
Filed: 2006-03-15
Abstract: A method of calculating a system level air data parameter for an aircraft using a flush air data system includes measuring local static pressures using the pressure sensing ports. Next, impact pressure effecting conditions are determined. Based on the determined impact pressure effecting conditions, one of multiple different algorithms is selected for generating an impact pressure dependent parameter. The impact pressure dependent parameter is then generated using the selected algorithm. Finally, the system level air data parameter is calculated as a function of the generated impact pressure dependent parameter. A flush air data system includes the flush static pressure sensing ports and an air data computer configured to implement the steps of the method. The system improves the reliability of air data parameter calculated when an aircraft is at a high angle of attack.
