20130200603 | PEDESTRIAN PROTECTION AIRBAG - A pedestrian protection airbag system for a vehicle includes an airbag that is adapted to be deployed along a windscreen and/or A-pillars of the vehicle, is inflatable to a deployed state and has projected periphery. The airbag system further comprises at least one tethering member connecting a first region of the airbag with a second region of the airbag along a path, the path being arranged within the projected periphery of the airbag when the airbag is in the deployed state. A vehicle comprising such a pedestrian protection airbag system and a method of deployment of an airbag of such a pedestrian protection airbag system are also provided. | 08-08-2013 |

20090185515 | Communication system - A method for removing an echo component in a first signal received at an audio input device, said method comprising the steps of outputting a second signal from an audio output device, receiving at the audio input device the first signal wherein the echo component in the first signal is the result of the second signal traversing an echo path having a frequency response which defines the relationship between the echo component and the second signal; determining an echo path model indicating an estimate of the frequency response of the echo path; removing an estimate of the echo component from the first signal using the echo path model; detecting if the first signal is overloaded; and wherein if it is detected that the first signal is overloaded the step of determining an echo path model comprises determining an overload echo path model such that the estimate of the frequency response indicated by the overload echo path model is only allowed to increase over time regardless of whether the frequency response of the echo path is decreasing over time. | 07-23-2009 |

20090185674 | Communication system - In an embodiment, a method for removing an echo component is a first signal received at an audio input device includes outputting a second signal from an audio output device, receiving at the audio input device the first signal wherein the echo component in the first signal is the result of the second signal traversing an echo path; detecting if the first signal only comprises the echo component; determining an estimate indicative of the echo path by comparing the first signal and the second signal when it is detected that the first signal only comprises echo; applying the estimate indicative of the echo path to the first signal to determine an equalised first signal; comparing the equalised first signal with the second signal to determine an estimate indicative of the echo component; and removing the echo component from the first signal in dependence on the estimate indicative of the echo component; wherein the step of detecting if the first signal only comprises the echo component comprises comparing a characteristic of the equalised first signal to a characteristic of the second signal. | 07-23-2009 |
20120163612 | Communication System - An echo component of a first signal received at an audio input device is removed. A second signal is output from an audio output device. The echo component in the first signal is the result of the second signal traversing an echo path. The characteristics of the first and second signals are compared, and if the first signal only comprises the echo, an estimate of the echo path is determined by comparing the first and second signals. The echo path estimate is applied to the first signal to determine an equalised first signal, which is is compared with the second signal to determine an estimate of the echo component. The echo component from the first signal is removed in dependence on the estimate of the echo component. | 06-28-2012 |
