Publication number: 20200274851Abstract: In some examples, an automobile comprises a plurality of electrical components interconnected by a communication network. The automobile comprises a set of policies that logically partition the electrical components of the automobile into a first zone having one or more of the critical components and a second zone having one or more of the non-critical components, the policies specifying rules for communication between the zones defined for the communication network within the automobile. The automobile further comprises a security gateway embedded within the automobile and coupled, by the communication network, to the one or more critical components and the one or more non-critical components. The security gateway is configured to provide security operations by applying the policies to communications within the automobile to determine, based on the rules defined by the policies, whether to forward or drop data packets communicated on the communication network.Type: ApplicationFiled: December 23, 2019Publication date: August 27, 2020Inventors: Ming Qiao, Jan Smith

Patent number: 9762204Abstract: A piezoelectric resonator for use in a sensor arrangement for detecting or measuring an analyte in a medium, comprises a quartz crystal plate, having a first crystal surface and a second crystal surface. The first crystal surface is provided with a first electrode, which has a surface area of less than 15 mm2 and the second crystal surface is provided with a second electrode. The first electrode may have a rectangular surface shape. A flow cell for use in an apparatus for detecting or measuring an analyte in a medium, comprises walls that form a sensing chamber together with the resonator, and inlet and outlet openings for leading a fluid through the sensing chamber. A part of the resonator constitutes one of the walls of the sensing chamber and is arranged such that the first electrode is situated inside the sensing chamber.Type: GrantFiled: December 19, 2011Date of Patent: September 12, 2017Assignee: ATTANA ABInventors: Teodor Aastrup, Jan Smith, Henrik Anderson

Patent number: 8591812Abstract: A piezoelectric sensor arrangement for analysis of fluid samples includes a signal source, a measuring device and a docking system. The sensor arrangement comprises a first part capable of receiving a sensor element that exposes a piezoelectric quartz crystal, a second part comprising fluid channels for the sample and a flow cell element, which preferably is removable and which comprises a recess, and inlet and outlet fluid channels for leading a fluid through the recess. The first and second parts are movable in relation to each other between a closed position and an open position and are arranged such that in the closed position the recess of the flow cell element is sealingly covered by the piezoelectric quartz crystal so that a flow cell is formed by the flow cell element and the quartz crystal.Type: GrantFiled: December 18, 2003Date of Patent: November 26, 2013Assignee: AttanaInventors: Teodor Aastrup, Jan Smith, Henrik Anderson

Patent number: 7771657Abstract: A system, device and method for detection of several individual analytes in a test solution aliquot (83) with an array of individually operated piezoelectric crystal microbalances are described. The system comprises a connecting station (100) that receives a plurality of individually specific piezoelectric crystal microbalance flow-trough cells (10), each containing a piezoelectric crystal (50) carrying electrodes (56,62) and a coating (66,46) exposing a first member of an interaction pair specific for an individual analyte being a second member of the interaction pair. Flowing means (70) flows a solution (75) and the test solution aliquot (83) to and through a cell compartment of each of the cells (10) via the connecting station (100). Power and measurement means (130) oscillate the piezoelectric crystal(s) (50). A change in oscillating characteristics of the crystal(s) (50), following interaction between the first and second members of the interaction pair, detects presence of the individual analyte(s).Type: GrantFiled: June 18, 2003Date of Patent: August 10, 2010Assignee: Biosensor Applications Sweden ABInventors: Per Månsson, Henrik Andersson, Jan Smith, Kjeld Jensen, Teodor Aastrup

Patent number: 7089812Abstract: An apparatus (10) and a method for concentrating and transferring volatile compounds contained in a sample on a detachable solid support (12) into a liquid for subsequent detection and/or analysis of the volatile compounds, are described. The apparatus comprises a holder (14) for the solid support (12), means (16) for transporting the holder (14) to a heating position on a heatable plate (18), an enclosed space-creating arrangement comprising the heatable plate (18) attached to a movable housing (30), the holder (14), the solid support (12), a funnel (20) on the solid support (12), and inside the funnel (20) a chilled member (22), means inside the housing (30) for heating the heatable plate (18) to evaporate the volatile compounds which then are condensed on the chilled member (22), means (24) for transporting the chilled member (22) from a cooler (26) to the inside of the funnel (20) and from there to a position (28) where condensed compounds are removed from the chilled member (22) into a liquid.Type: GrantFiled: November 19, 2002Date of Patent: August 15, 2006Assignee: Biosensor Applications Sweden ABInventors: Per Månsson, Jan Smith, Ann-Charlotte Hellgren
