Patent number: 8302731Abstract: The present invention provides a hearing protector comprising two ear cups which are designed to cover the ears of the wearer of the hearing protector, and sealing rings (2) which are secured along the peripheries of the ear cups, the sealing rings each displaying at least one circumferential lamella (5, 6, 7), being manufactured from a resilient, possibly elastic material, and being formed to sealingly abut, around the wearer's ears, against the wearer's head, wherein the lamella (5,6, 7), at least along its edge regions located most proximal the wearer's head, display portions (13, 14, 15) which, in a direction towards the wearer, are arched from a central region (3) in the sealing ring (2) out towards its periphery (1).Type: GrantFiled: March 5, 2010Date of Patent: November 6, 2012Assignee: 3M Innovative Properties CompanyInventors: Sigvard Nilsson, Henrik Nordin

Patent number: 8243943Abstract: A hearing protector comprises a hearing hood (2), a microphone (7), a loudspeaker and an amplifier. The hearing hood (2) has passive noise damping. The microphone (7) is disposed exteriorly on the hearing protector, while the loudspeaker is disposed inside the hood. The amplifier amplifies and transmits the signals from the microphone (7) to the loudspeaker. The noise damping of the hearing hood (2) is broad band. The frequency range of the amplifier corresponds to the frequency range of human speech. The amplification of the amplifier is variable and the greatest amplification is such that the sum total of the sound levels that are caused, on the one hand, by ambient sound passing through the hood (2) and, on the other hand, by sound from the loudspeaker amounts to a maximum, predetermined value.Type: GrantFiled: November 23, 2004Date of Patent: August 14, 2012Assignee: 3M Svenska AktiebolagInventors: Henrik Nordin, Sigvard Nilsson

Patent number: 7870843Abstract: An engine control system includes a scavenging module that generates a scavenging signal when both a driver torque request is greater than a predetermined torque threshold and a rotational speed of an engine crankshaft is less than a predetermined speed threshold. A cam phaser control module controls intake and exhaust cam phasers based on the scavenging signal such that opening times of intake and exhaust valves of a respective cylinder overlap.Type: GrantFiled: February 24, 2009Date of Patent: January 18, 2011Inventors: Layne K. Wiggins, Michael Livshiz, Jeffrey M. Kaiser, Henrik Nordin

Publication number: 20050238181Abstract: A hearing protector device is provided including a sound attenuating body and an electronic unit having a microphone, an amplifier, and a loudspeaker, where the electronic unit is selectively activated and, when activated, receives sound from an ambient environment, amplifies a frequency range of the received sound corresponding to a frequency range of human speech, and varies said amplification such that a total level of sound passing through the body and through the electronic unit does not exceed a maximum predetermined sound level.Type: ApplicationFiled: November 29, 2004Publication date: October 27, 2005Inventors: Sigvard Nilsson, Henrik Nordin

Publication number: 20030000211Abstract: In an internal-combustion engine having an exhaust-gas driven supercharger (8) and having at least two exhaust-gas valves (2, 3) per cylinder, a first exhaust-gas valve (2) in each cylinder is connected to a first exhaust manifold (4), whilst a second exhaust-gas valve (3) in each cylinder is connected to a second exhaust manifold (5). The two exhaust manifolds (4, 5) lead to at least one exhaust-gas turbine in at least one turbo compressor and the first exhaust-gas valves (2) are arranged to be opened at all engine speeds, whilst the second exhaust-gas valves (3) are arranged to be opened only at higher engine speeds. The first exhaust manifold (4) has a smaller flow area than the second exhaust manifold (5). By choosing which exhaust-gas valves are to be used, the size of the flow ducts between engine and exhaust-gas turbine can easily be suited to the size of the exhaust-gas flow which is available at the time.Type: ApplicationFiled: July 1, 2002Publication date: January 2, 2003Applicant: Saab Automobile ABInventors: Hans Drangel, Hans Karlsson, Anders Larsen, Henrik Nordin

Patent number: 5384857Abstract: A snap-in attachment of a headband or other support means for a hearing-protection cup is described. The snap-in contact comprises a sliding pin (6) the journal section (7) of which is oval or elliptical in cross section, and a jaw element with two resiliently deformable jaws (11, 12). The inner walls (21, 22) of the jaws (11, 12) and the wall section (20) connecting them define a locking space (13). The journal section (7) of the sliding pin can be inserted into the locking space (13) against a resilient counter member only in the direction of the longitudinal axis of the journal section (7) and is thus lockable between the jaws (11, 12) in a first locked position. After being turned (angle .alpha.) against another resilient counter member, the sliding pin is locked by its journal section (7) in the locking space (13) in a second locked position, in which it is pivotable to a limited extent (sector with angle .beta.).Type: GrantFiled: October 26, 1993Date of Patent: January 24, 1995Assignee: Peltor AktienbolagInventors: Henrik Nordin, Sigvard Nilsson

Patent number: 5239703Abstract: The visor arrangement of the present invention includes a visor element and support apparatus to support the element in a pivotable state between a lowered, operative position and a raised, inoperative position on a protective helmet or other holder which can be applied on the user's head. The support apparatus is a pair of support arms, each consisting of two detachably connectable parts pivotable in relation to each other. One of the parts is provided with a laterally protruding journalling-pin element, while the other is provided with a laterally running through-opening into which the journalling pin can be inserted.Type: GrantFiled: September 9, 1992Date of Patent: August 31, 1993Assignee: Peltor AktiebolagInventors: Henrik Nordin, Jan-Olof Fag
