| 20120210137 | SECURE ID CHECKING - A cost-effective system that provides for the efficient protection of transmitted non-public attribute information may be used, for example, to control access to a secure area. Encryption of the attribute information may be performed using symmetric encryption techniques, such as XOR and/or stream cipher encryption. A centralized database that stores and transmits the encrypted attribute information may generate the encryption/decryption key based on selected information bytes, for example, as taken from a card inserted into a handheld device used at the secure area. The selected information to generate the encryption key stream may be varied on a periodic basis by the centralized database. Information as to which selected bytes are to be used for a particular access authorization request may be transmitted to the handheld unit or may be input through action of a user of the handheld unit, for example by entry of a PIN code. | 08-16-2012 |

| 20150231542 | AIR PURIFIER DEVICE WITH COUPLING MECHANISM - An air purifier device is provided including a fan unit including a fan arranged to produce an air flow through the air purifier device, and a filter unit including a filter arranged to filter the air flow produced by the fan. The filter unit is adapted to stand on a support surface when the air purifier device is positioned for use. The air purifier device further includes a coupling mechanism arranged to secure the fan unit on top of the filter unit. The coupling mechanism includes two release means arranged on opposite outer sides of the fan unit, and the fan unit is releasable from the filter unit by actuating the two release means. The filter unit may be removed from the fan unit by a single action (or movement) by the user, whereby filter replacement of the air purifier device is facilitated. | 08-20-2015 |
| 20150231543 | AIR PURIFIER DEVICE WITH FAN DUCT - An air purifier device is provided including a fan arranged to produce an air flow through the air purifier device, and a fan duct for guiding the air flow produced by the fan. The fan duct extends in an upright direction of the air purifier device. The air purifier device further includes an air intake arranged below a lower end of the fan duct, and an exhaust arranged at an upper end of the fan duct so as to exhaust purified air in an upward direction from the air purifier device when the air purifier device is in use. The fan duct is flared in direction from an intermediate portion of the fan duct towards both it ends, and the fan is arranged at least partly in the intermediate portion. A facilitated circulation of air through the room and through the air purifier device standing in the room is provided. | 08-20-2015 |
| 20150231645 | AIR PURIFIER DEVICE WITH IONIZING MEANS - An air purifier device includes a chamber defined by a side wall arranged to guide an air flow through the air purifier device. The air purifier device further includes at least one emitter electrode and at least one collector plate electrode arranged to ionize airborne particles. The at least one emitter electrode is arranged to extend from the side wall and inwards in the chamber and the at least one collector plate electrode is arranged to extend from the side wall and inwards in the chamber. The air purifier device enables the side wall to be manufactured from e.g. plastic, or other non-conductive or non-magnetic material. This in turn may enable a lower weight of the air purifier device and facilitated manufacturing, as the side walls of the chamber e.g. may be formed by plastic moulding just as many other parts of the air purifier device. | 08-20-2015 |

| 20130041523 | METHOD AND SYSTEM FOR PROTECITON OF SUBSEA ASSETS - The present invention relates to a method and a system for protection of subsea assets, which system comprises an electronic map indicating subsea assets, the system defines a geographical zone, which zone covers an area around the subsea asset, which system performs tracking of vessels entering a geographical zone by analysing electronic signal transmitted or reflected from the vessel. Performing an analysis of a sailing pattern in the geographical zone, the system can define at least one event based on sailing patterns, which system scores the events, the system count the scores, and based of a defined level of scores the system generates an alarm, based on the alarm the system generates a warning, which warning can be transmitted to the vessel. By this system there can be placed a computer system at a coast control center, where all data about vessels are picked up. This way, the system can transmit an alarm to a vessel if the vessel performs critical behaviour near subsea assets. | 02-14-2013 |
