Title: Cable guide support for cable-guided tank gauge
Inventor: WINTERFORD BOB
IPC: F16H55/36
Filed: 2006-01-13
Abstract: A tank gauge system is provided comprising a float, a cable, an indicator and at least one cable guide support. The float is in a tank containing liquid and moves with it. The cable connects the float to the indicator on the outside through the cable support for communicating the liquid level in the tank. The cable support comprises a body having two side openings merging into a cavity formed on a top portion of the body. A roller is positioned in the cavity, between the two openings and is rotatable about an axis transverse to the direction of cable movement. The roller has a predetermined axial length that is substantially wider than each of the openings so that the cable moving through the openings is urged to maintain contact with the roller. This prevents the cable from coming off the roller and minimizes jamming.

Title: Method for operating a detector for identifying the overlapping of flat mail in a sorting machine
Inventor: ROMPE ANDRE
IPC: B65H7/12
Filed: 2004-07-27
Abstract: The invention relates to a method whereby the average costs CNDD for each unidentified overlap in a distribution and sorting process and the average costs CRF for the renewed sorting and distribution of each identified overlapped item of mail are determined. Before the sorting operation, the identification rate DR(Pi) of the detector is determined at different working points according to an adjusting parameter Pi. During the sorting operation, the respective actual overlap rate DFR'(Pi) of the sorting machine is estimated, for defined time intervals, from the identification result, the identification rate DR(Pi) and the error rate ER(Pi), according to the adjusting parameters Pi. The actual adjusting parameter Popt with the greatest utility CB'(Popt), which is used to operate the detector until the next interval, is determined by optimisation calculations from the relation for the utility CB'(Pi) of the sorting and distribution process CB'(Pi) = N{( DFR'(Pi)*DR(Pi)*(CNDD-CRF)) - (ER(Pi)*CRF*(1-DFR'(Pi)))} for the operator.

Title: Staggered pilot transmission for channel estimation and time tracking
Inventor: VIJAYAN RAJIV
IPC: H04L25/02
Filed: 2005-04-25
Abstract: To allow a receiving entity to derive a longer channel estimate while limiting overhead, a transmitting entity transmits a pilot on different groups of subbands in different time intervals. N subbands in the system are arranged into M nonoverlapping groups. Each group includes subbands that are uniformly distributed across the N subbands. The transmitting entity transmits the pilot on a different subband group in each time interval, and selects all M subband groups in M time intervals based on a pilot staggering pattern. The receiving entity derives (1) an initial impulse response estimate with P channel taps based on the pilot received on one subband group and (2) two longer impulse response estimates with different lengths used for data detection and time tracking.; Each longer impulse response estimate may be derived by filtering initial impulse response estimates for a sufficient number of subband groups using a time-domain filter.

Title: Multimodal disambiguation of speech recognition
Inventor: LONGE MICHAEL
IPC: G10L15/18
Filed: 2005-06-02
Abstract: The present invention provides a speech recognition system combined with one or more alternate input modalities to ensure efficient and accurate text input. The speech recognition system achieves less than perfect accuracy due to limited processing power, environmental noise, and/or natural variations in speaking style. The alternate input modalities use disambiguation or recognition engines to compensate for reduced keyboards, sloppy input, and/or natural variations in writing style. The ambiguity remaining in the speech recognition process is mostly orthogonal to the ambiguity inherent in the alternate input modality, such that the combination of the two modalities resolves the recognition errors efficiently and accurately. The invention is especially well suited for mobile devices with limited space for keyboards or touch-screen input.
