Abstract:

A paddle switch safety button which prevents the paddle switch from being activated prior to the safety button being depressed. A unique multi cross section stem of the safety button cooperates with a U-shaped cutout in the paddle switch lever. The stem interferes with the lever in its extended position and passes in the U-shaped notch in the depressed position to allow the paddle switch lever to be operated.

Abstract:

A feature transform for speech recognition is described. An input speech utterance is processed to produce a sequence of representative speech vectors. A time-synchronous speech recognition pass is performed using a decoding search to determine a recognition output corresponding to the speech input. The decoding search includes, for each speech vector after some first threshold number of speech vectors, estimating a feature transform based on the preceding speech vectors in the utterance and partial decoding results of the decoding search. The current speech vector is then adjusted based on the current feature transform, and the adjusted speech vector is used in a current frame of the decoding search.
