Abstract: A force sensing system for determining if a user input has occurred, the system comprising: an input channel, to receive an input from at least one force sensor; an activity detection stage, to monitor an activity level of the input from the at least one force sensor and, responsive to an activity level which may be indicative of a user input being reached, to generate an indication that an activity has occurred at the force sensor; and an event detection stage to receive said indication, and to determine if a user input has occurred based on the received input from the at least one force sensor.

Abstract: Audio signal processing techniques are described which are employed within a circuit of a speech dereverberation system. The amount of data or number of samples input to a reverberation coefficient determination unit is determined, taking into account information about the background noise in the acoustic space and information about energy of reverberant sound in the acoustic space.
