Abstract: The invention relates, in general, to methods of processing Lignocellulosic biomass to fermentable sugars and to methods that rely on hydrothermal pretreatment. Xylose monomer yields comparable to those achieved using two-stage pretreatments can be achieved from soft Lignocellulosic biomass feedstocks by pretreasting to very low severity in a single-stage pressurized hydrothermal pretreatment, followed by enzymatic hydrolysis to release xylose retained in the solid state. In some embodiments, pretreated biomass is separated into a solid fraction and a liquid fraction, the solid fraction subjected to enzymatic hydrolysis, and the separated liquid fraction subsequently mixed with the hydrolysed solid fraction.

Abstract: A video system and method are presented that uses an output-receiving microphone mounted on the housing of the video system to receive a signal representative of the output of a speaker in a use-environment. This signal is compared with a second signal received from a spoken-word microphone that is mounted more remotely from the speaker. In some embodiments, the spoken-word microphone is positioned in a low-pass filter tune pipe and is combined with a separate spoken-word microphone in a tuned microphone array so as to filter out frequencies not associated with the human voice. The two signals are magnitude matched, and the first signal is subtracted from the second to generate an improved voice signal for a voice recognition system.

Abstract: An audio device for receiving radio communication. The audio device is configured to receive radio communication as a received radio signal. The audio device includes a hear-through element configured to provide a hear-through signal to a user in response to a received ambient sound signal, and an adaptive auto-gain element configured to perform an auto-gain function of the received radio signal according to an adaptive gain value resulting in a modified radio signal, and to set the adaptive target level for the auto-gain function in response to the hear-through signal.

Abstract: The invention relates, in general, to methods of processing lignocellulosic biomass to fermentable sugars and to methods that rely on hydrothermal pretreatment. Xylose monomer yields comparable to those achieved using two-stage pretreatments can be achieved from soft lignocellulosic biomass feedstocks by pretreating to very low severity in a single-stage pressurized hydrothermal pretreatment, followed by enzymatic hydrolysis to release xylose retained in the solid state.

Abstract: A method and system for noise suppression of a sound signal. The sound signal includes speech of a user while speaking. The system includes a first sound receiver that obtains a first sound signal and a second sound receiver that obtains a second sound signal. The first sound signal includes a first airborne noise signal when noise is present and a first airborne speech signal when the user is speaking. The second sound signal includes a second airborne noise signal when noise is present and a second airborne speech signal when the user is speaking. The first sound receiver is a vibration pickup or transducer that obtains an additional speech signal when the user is speaking. The additional speech signal is obtained in response to vibrations propagating through the user, the vibrations being caused by the user speaking, and the first sound signal includes the additional speech signal when the user is speaking.

Abstract: The present invention relates to a process for production of fermentation products, including bioethanol by non-pressurised pre-treatment, enzymatic hydrolysis and fermentation of waste fractions containing mono- and/or polysaccharides, having a relatively high dry matter content. The process in its entirety, i.e. from non-pressurised pre-treatment over enzymatic hydrolysis and fermentation to sorting of fermentable and non-fermentable solids can be processed at a relatively high dry matter content in a single vessel or similar device using free fall mixing for the mechanical processing of the waste fraction.

Abstract: A bone conduction microphone device that registers speech signals from a user. The microphone device includes a housing having an abutment or contact part, which has a central axis substantially parallel to a predetermined distal direction and a predetermined proximal direction. The abutment, during use, abuts against and is in vibratory contact with tissue of a head or neck of the user, and receives, during use, vibrations, representing a speech signal and propagating through at least a part of the user's tissue or bone structures in the head or neck when the user is speaking. The housing further includes or is connected to at least one sealing element, which substantially or at least partly encircles the abutment or contact part about the central axis.
