Patent number: 10356516Abstract: 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.Type: GrantFiled: May 18, 2016Date of Patent: July 16, 2019Assignee: Nextlink IPR ABInventors: Jan Larsen, Dennis Normann Andersen

Patent number: 9920345Abstract: Methods of processing lignocellulosic biomass to fermentable sugars are provided which rely on hydrothermal pretreatment. Soft lignocellulosic biomass feedstock is pretreated in a single-stage pressurized hydrothermal pretreatment to very low severity. The pre-treated biomass is hydrolysed, typically as a whole slurry, using enzymatic hydrolysis catalysed by an enzyme mixture comprising endoglucanase, exoglucanase, ?-glucosidase, endoxylanase, and ?-xylosidase activities at activity levels in nkat/g glucan of endoglucanase of at least 1100, exoglucanase of at least 280, ?-glucosidase of at least 3000, endoxylanase of at least 1400, and ?-xylosidase of at least 75, so as to produce a hydrolysate in which the yield of C5 monomers is at least 55% of the original xylose and arabinose content of the feedstock prior to pretreatment.Type: GrantFiled: February 5, 2014Date of Patent: March 20, 2018Assignee: INBICON A/SInventors: Jan Larsen, Niels Nielsen Poulsen, Martin Dan Jeppesen, Kit Kellebjerg Mogensen

Patent number: 9758843Abstract: The invention relates to a method of processing lignocellulosic biomass comprising: providing lignocellulosic biomass feedstock; pretreating said biomass feedstock by continuous hydrothermal pretreatment in a pressurized reactor; measuring xylan number or lignin number in the output stream of pretreated biomass from the pretreatment reactor; and controlling the pretreatment reactor so as to maintain, in the output stream of pretreated biomass, a pre-determined level of measured xylan number or lignin number. The method allows for continuously controlling the digestibility of a lignocellulosic biomass during the step of pretreatment, and accordingly provides a continuous estimate of the severity of the pretreatment.Type: GrantFiled: January 16, 2013Date of Patent: September 12, 2017Assignee: INBICON A/SInventors: Jan Larsen, Kit Kellebjerg Mogensen, Pia Jørgensen

Patent number: 9628964Abstract: The present invention relates to communications systems incorporating peripheral devices such as a push-to-talk (PTT) or similar and interface cables to connect these to a headset and/or a communication device such as a man worn two-way radio, vehicle intercom system, mobile phone, etc. In particular, the invention relates to such interface cable having an integrated functionality. The basic idea of the invention is to use an interface between a first and a second device in a voice communication system, which interface is specific to the second device and holds digital information allowing the first device to identify or adapt to the second device. This allows the first device to automatically adapt its settings and/or functionality to, and thus to function with, several different second devices without any need for updating, re-configuration, or user intervention.Type: GrantFiled: September 10, 2015Date of Patent: April 18, 2017Assignee: Nextlink IPR ABInventors: Ljupco Trajkovski, Steen Iversen, Jan Larsen

Publication number: 20170009261Abstract: A range of concentrations exists in which fermentation inhibitors derived from pretreatment of lignocellulosic feed stocks inhibit growth of lactic acid bacteria without affecting fermentive yeast. By optimizing levels of fermentation inhibitors to fall within this range, yeast fermentations of lignocellulosic biomass can be conducted under non-sterile conditions with ethanol yields comparable to those achieved under sterile conditions. Optimised inhibitor levels can be achieved by controlling the water/biomass ratio of a lignocellulosic biomass during and after pretreatment, for example by washing the fiber fraction of a previously pretreated lignocellulosic biomass with a pre-defined amount of fresh water or recycled process solutions. Crude extracts of liquid fraction or process solutions from pretreatment of lignocellulosic biomass can also provide an effective anti-baterial treatment for first generation starch fermentations.Type: ApplicationFiled: April 16, 2014Publication date: January 12, 2017Applicant: Inbicon A/SInventor: Jan Larsen

Publication number: 20150213710Abstract: An apparatus and a method are provided for a wireless Infrared (IR) converter to operate a legacy device by translating wireless commands into IR codes for transmission to an IR receiver within the legacy device. The wireless IR converter comprises a wireless control chip which receives commands from external wireless devices, and an IR output configured to convey IR codes to the IR receiver of the legacy device. Upon receiving commands from the wireless control chip, a microcontroller within the apparatus accesses a macro command library and an IR command library stored on a non-transitory machine-readable medium within the wireless IR converter. The macro command library and the IR command library enable the microcontroller to select IR codes corresponding to the received wireless commands. Once proper IR codes are selected, the IR output transmits the IR codes to the legacy device.Type: ApplicationFiled: January 27, 2014Publication date: July 30, 2015Inventors: Jim Kinne, Jan Larsen, Larry Jacoby, Jeff Haagenstad
