PCT No. PCT / GB95 / 02618 Sec. 371 Date Jul. 2, 1997 Sec. 102(e) Date Jul. 2, 1997 PCT Filed Nov. 7, 1995 PCT Pub. No. WO96 / 15597 PCT Pub. Date May 23, 1996An echo detecting system includes data stores for storing signals from up and down channels respectively. The signals undergo pre-processing to identify signals forms characteristic of speech and instruct a measurement unit to carry out comparison using cross-correlation techniques between the signals stored in the stores only when such characteristics are detected. This reduces the processing power required and raises the accuracy of the correlations. Parallel processing techniques allow echoes with longer delay periods to be detected. The results of the measurement may be used to generate an echo-cancellation signal.

In a scheme for accessing a wireless network, a backoff delay time period representing a duration of time that is to elapse before a station is permitted to attempt a retransmission is selected from a group of delay periods. The group of delay periods grows at a rate that is less than exponentially (e.g. linearly) based on the number of attempted retransmissions. Selection of the backoff delay time period may entail random selection of an integer N from a contention window and multiplication of N by a slot time duration. The contention window may be a range of integers [0, W-1]. The contention window size W may be initialized to a predetermined minimum value upon a first attempted transmission and may be capped at a predetermined maximum value. Average backoff delay may be reduced in comparison to a binary exponential backoff approach.

User interface approaches to providing help to players by playing back previously recorded inputs. Certain exemplary embodiments involve displaying, with the recorded playback, an input device icon to show where the inputs are occurring and / or where the inputs should occur if the player were to make them. Modifications are made to the previously recorded input to improve the user's ability to see what is happening, as well as making the playback seem more consistent, mechanical, and automatic. The help makes the computer application seem like the user interface is operating itself in a way that is easy to follow, rather than giving the impression that a previously recorded user input stream simply is being played back in accordance with the more organic and potentially idiosyncratic behaviors of the recorded person. The modifications may in certain exemplary embodiments include, for example, path smoothing / correction, automatic snapping, delay periods, speed normalization, etc.

A method of manufacturing an overbased calcium sulfonate grease comprising a reduced amount of overbased calcium sulfonate, water and at least one non-aqueous converting agent, where at least a portion of the non-aqueous converting agent is added after one or more delay periods relative to the addition of the water. A delay period may involve the period of time it takes to adjust the temperature of the mixture, a period of time during which the mixture is held at a temperature or within a range of temperatures, and multiples and any combination thereof. These calcium sulfonate greases have improved thickener yield and high dropping points compared to greases of substantially similar composition made without a delay between the additions of water and a non-aqueous converting agent, particularly when a poor quality overbased calcium sulfonate is used.

For control, some memory circuits use a delay-locked loop to generate a set of signals, each delayed a different amount relative a reference signal. However, as circuits get faster and faster, conventional delay-locked loops require use of extra interpolation circuitry to generate smaller delays, and thus consume considerable power and circuit space. Accordingly, the inventor devised a circuit which interlaces and synchronizes two delay-locked loops, each including a number of controllable delay elements linked in a chain. In one embodiment, the first loop produces a sequence of clock signals delayed an even number of delay periods relative a reference clock signal, and the second loop produces a sequence of clock signals delayed an odd number of delay periods relative the reference clock signal. In addition, the first and second loops are synchronized.

The timing of the clutch elements during the power-on skip through neutral downshift is established by calculating delay periods for the off-going and on-coming clutches such that a predetermined desired shift time is met.

Each type of departure calls for a particular remedy, and a suitable adjustment is calculated thereafter implemented by changing one or more initial conditions for the next shift of the same type.
