  • Patent number: 8438837
    Abstract: The present invention involves a method for maintaining temperature in an exhaust gas treatment device for an internal combustion engine in a hybrid vehicle. The engine has a crankshaft and at least one cylinder. The hybrid vehicle has a fuel storage device and a fuel supply device. An exhaust gas treatment device is located downstream of the cylinder. The method comprises, in an engine off mode, pumping air to the exhaust gas aftertreatment device controlling the fuel supply device so that fuel is allowed to the exhaust gas aftertreatment device. Air flow to the exhaust gas aftertreatment device can be controlled by a throttle in an inlet duct to the engine and/or the fuel supply device to control the combustion and air-fuel ratio in the exhaust gas treatment device.

  • Patent number: 8020373
    Abstract: A method and a system for regenerating an exhaust gas treatment device for an internal combustion engine having at least one cylinder are presented. The system comprises an exhaust gas treatment device, a fuel storage means, a fuel vapor retainer, and an engine control unit adapted to selectively allow fuel vapors from the fuel vapor retainer to reach the engine. The method comprises regenerating an exhaust gas treatment by allowing fuel vapors from the fuel vapor retainer into at least one of the engine cylinders, and inhibiting combustion in at least one of the cylinders into which fuel vapors are to allowed.

  • Publication number: 20080148718
    Abstract: A method for an exhaust gas treatment device (8) in an engine system, and an engine system comprising an internal combustion engine with at least one cylinder (2) are presented. The engine system further comprises an exhaust gas treatment device (8), fuel storage means (20), a fuel vapor retainer (22), and an engine control unit adapted to control valve means (25) so as to selectively allow purge gas from the fuel vapor retainer (22) to reach the engine. The method comprises performing a purge gas exhaust gas treatment device regeneration (207), comprising allowing to purge gas from the fuel vapor retainer (22) into at least one of the cylinders (2), and inhibiting combustion in at least one of the cylinders (2) into which purge gas is allowed.

  • Publication number: 20070211573
    Abstract: Electronic equipment, such as a mobile phone, PDA or other device, is operative to transmit information to another electronic equipment when the two are moved, e.g., shaken, at substantially the same frequency and amplitude. The transferred information may be contacts or other information. The electronic equipment include a motion transducer providing motion signals representing motion and a comparator that compares motion signals to determine whether substantially the same motion is occurring to both electronic equipment; if affirmative, a substantially secure communication link is established over which information may be transmitted between electronic equipment. A method of transmitting information includes detecting occurrence of motion and in response thereto transmitting information. A method also includes simultaneously shaking at least two electronic equipment together to establish conveniently a secure communication link and communication protocol between the electronic equipment.

  • Patent number: 5211641
    Abstract: A disposable absorbent article, such as a diaper, an incontinence guard or the like, includes an inner, liquid-permeable casing sheet, which when the article is worn lies nearest the body of the wearer, an outer, liquid-impermeable casing sheet, an absorbent pad enclosed between the two casing sheets, and a layer of fibre wadding disposed between the absorbent pad and the inner casing sheet. The inner casing sheet is joined to the absorbent pad along two longitudinal lines forming permanent fold lines which divide the article, over at least a part thereof, into a central elongated part and two edge-parts located symmetrically on respective sides of the central elongated part. Each edge-part is folded between the respective fold line and its lateral edge such as to form an inwardly upstanding longitudinal fold in the outer casing sheet.

  • Patent number: 4828555
    Abstract: An elongated absorbent article, such as a diaper or an incontinence protector, comprises an absorption body disposed in a casing and having between its two ends a crotch portion. The absorption body comprises a bottom sheet (1) and a top sheet (2), the top sheet being adapted to lie in contact with the wearer and to serve as a spacer means between the skin of the wearer and the bottom sheet. The top sheet (2) has parts (9, 10) which are located along two side-edge portions of the bottom sheet and which define laterally between them at least one space (7) around a wetting point of the article.
