摘要： A system and method of signal processing for a hearing implant. The hearing implant includes at least one electrode, each electrode associated with a channel specific sampling sequence. An acoustic audio signal is processed to generate for each electrode a band pass signal representing an associated band of audio frequency. For each electrode, a sequence signal is determined as a function of the electrode's associated band pass signal and channel specific sampling sequence. An envelope of each band pass signal is determined. The envelope of each band pass signal is filtered to reduce modulations resulting from unresolved harmonics, creating for each electrode an associated filtered envelope signal. Each electrode's sequence signal is weighted based, at least in part, on the electrode's associated filtered envelope signal.

摘要： A system and method for activating stimulation electrodes in cochlear implant electrode is described. A preprocessor filter bank processes an input acoustic audio signal to generate band pass signals that each represent an associated band of audio frequencies. An information extractor extracts stimulation signal information from the band pass signals based on assigning the band pass signals to corresponding electrode stimulation groups that each contain one or more stimulation electrodes, and generates a set of stimulation event signals for each electrode stimulation group that define electrode stimulation timings and amplitudes. A pulse selector selects a set of electrode stimulation signals from the stimulation event signals based on a pulse weighting function that uses channel-specific weighting factors favoring lower frequencies for activating the stimulation electrodes to stimulate neighboring audio nerve tissue.

摘要： A method is described for delivering stimulation signals in an implantable multichannel neuro-stimulating device such as a cochlear implant. A stimulation channel is selected for delivering a data stimulation signal. One or more desensitization channels spatially adjacent to the stimulation channel are also selected. One or more non-data desensitization signals are delivered on the desensitization channels during a desensitization period before delivery of the data stimulation signal, and then the data stimulation signal is delivered on the stimulation channel. The stimulation channel may be blanked to prevent stimulation signals during a sensitization period before delivering the data stimulation signal.

摘要： A method and a device for controlling automatic emergency braking of a motor vehicle to reduce the severity of a collision of a vehicle with an object, the position and/or speed of the object with respect to the host vehicle being determined via an object detection device, and this information being sent to a collision detection device which ascertains whether a collision with an object is imminent and, on detecting a collision, triggers emergency braking and ascertains a collision instant, emergency braking being terminated after the period of time until the determined collision instant has elapsed.
