Patent number: 8200740Abstract: Disclosed is a method comprising steps of: a broker software application receiving a first published message on a topic from a publisher application and storing the first published message in a local storage location along with an indicator which indicates that the first published message originated from a publisher application that is local to the broker software application; the broker software application receiving a second published message on the topic from another broker software application and storing the second published message in the local storage location in place of the previously stored first published message, along with an indicator which indicates that the second published message originated from a publisher application that is remote to the broker software application; and the broker software application delivering the second published message, from the local storage location, to a requesting subscriber application which has requested a last retained publication message on the topic.Type: GrantFiled: January 2, 2009Date of Patent: June 12, 2012Assignee: International Business Machines CorporationInventors: Andrew D. Banks, Gavin D. Beardall, Adrian D. Dick, Ian C. Vanstone

Patent number: 8019847Abstract: When a new broker is connected to a network, a loop detection message is sent over the new connection created by the new broker. The loop detection message includes topics. At each receiving broker, topics that cannot be propagated to a neighbor broker are removed. If the loop detect message contains no topics, the loop detect message is not propagated further. If the loop detection message returns to the new broker, a loop is detected.Type: GrantFiled: May 13, 2008Date of Patent: September 13, 2011Assignee: International Business Machines CorporationInventors: Andrew D. Banks, Gavin Beardall, Adrian D. Dick, Ian C. Vanstone

Patent number: 7245729Abstract: A loudspeaker includes a box-form structure made from stiff lightweight sheet material to define a plurality of faces, at least one face of the structure forming a panel-form bending wave acoustic radiator, and an electro-acoustic vibration transducer coupled thereto to apply bending wave energy to the radiator to cause it to radiate an acoustic output when an input signal is applied to the transducer. The box-form structure is collapsible, so that the box-form structure can be stored and transported in a flat form and erected as a box when required as a loudspeaker.Type: GrantFiled: April 5, 2002Date of Patent: July 17, 2007Assignee: New Transducers LimitedInventors: Andrew D. Bank, Ian D. MacFarlane, Keith D. Hills, Paul Burton

Patent number: 6813362Abstract: A loudspeaker includes an assembly of at least two bending wave panel-form acoustic members each having a set of modes which are distributed in frequency. The parameters of at least two of the acoustic members are selected so that the modal distributions of each acoustic member are substantially different. The arrangement is such that the modal distributions of the assembly of acoustic members are interleaved constructively in frequency. A transducer applies bending wave energy to the acoustic members to cause them to resonate to produce an acoustic output. A method of making such a loudspeaker is also provided.Type: GrantFiled: April 5, 2002Date of Patent: November 2, 2004Assignee: New Transducers LimitedInventors: Andrew D. Bank, Ian D. MacFarlane, Keith D. Hills, Paul Burton, Neil Harris
