Patent number: 10965443Abstract: In various examples there is a communications network comprising a plurality of nodes connected via an interconnection medium to form a receive-from-many communications network. The network has a synchronisation mechanism which synchronizes a signal frequency of the nodes. The network has at least one store holding signal amplitude data of signals previously sent between specified pairs of nodes of the communications network. An amplitude controller uses the stored data to adjust amplitudes of signals communicated between at least one of the pairs of nodes of the communications network.Type: GrantFiled: June 18, 2019Date of Patent: March 30, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Istvan Haller, Krzysztof Jozwik, Hitesh Ballani, Paolo Costa, Benn Charles Thomsen, Foteini Karinou, Daniel Jonathan Finchley Cletheroe, Kai Shi, Sophie Gloria Lange

Publication number: 20200343680Abstract: A wavelength switchable laser is described which has a multi-wavelength laser source configured to generate signals at different wavelengths. The wavelength switchable laser has a wavelength selector with a plurality of electro-optical switches, each electro-optical switch being configurable to transmit or block output of one of the signals from the multi-wavelength source according to the wavelength of the signal.Type: ApplicationFiled: June 24, 2019Publication date: October 29, 2020Inventors: Sophie Gloria LANGE, Daniel Jonathan Finchley CLETHEROE, Benn Charles THOMSEN, Hitesh BALLANI, Kai SHI, Krzysztof JOZWIK, Foteini KARINOU, Raphael Eric Alfred BEHRENDT, Istvan HALLER, Hugh WILLIAMS, Paolo COSTA

Patent number: 7853218Abstract: A method of checking messages from a network of communication sources includes initially testing the signal strength of a plurality of communication sources, storing the identity of the communication sources with the two strongest signals, and alternatively entering a sleep mode and a wake-up mode, the wake-up mode synchronized to the communication source with the strongest signal. The method further includes testing the signal strength of one additional communication source, switching synchronization to the additional communication source if said source presents a signal stronger than the signal of a stored communication source with the strongest signal, and replacing the identity of any stored communication source if an additional communication sources tested in sequence presents a signal stronger than the signal of said stored communication source.Type: GrantFiled: August 12, 2009Date of Patent: December 14, 2010Assignee: Lojack Operating Company, LPInventors: Frank Romano, Sampath Krishna, Son Nguyen, Jesse Rhodes, Philip Grahame Crewe, Daniel Jonathan Finchley Cletheroe, Mark Marsden, Steven Walter Greendale, Nigel James Watson, Ian Christopher Stroud, Timothy David Howe, Gerard Edward Smith

Patent number: 7593711Abstract: A vehicle locating unit with improved power management. A receiver receives a signal from a network of communication sources. A signal strength monitoring subsystem determines which of the communication sources are transmitting the strongest signals. A power management subsystem is responsive to the signal strength monitoring subsystem and is configured to alternatively enter sleep and wake-up modes, synchronize the wake-up mode to the communication source transmitting the strongest signal, and test the signal strength of at least one additional communication source according to a predefined sequence.Type: GrantFiled: May 18, 2005Date of Patent: September 22, 2009Assignee: LoJack Operating Company, LPInventors: Frank Romano, Sampath Krishna, Son Nguyen, Jesse Rhodes, Philip Grahame Crewe, Daniel Jonathan Finchley Cletheroe, Mark Marsden, Steven Walter Greendale, Nigel James Watson, Ian Christopher Stroud, Timothy David Howe, Gerard Edward Smith

Patent number: 7511606Abstract: A vehicle locating unit with a receiver for receiving a signal from a network of communication sources, a transponder activated when a communication source sends a message to the receiver, and a power supply regulating circuit for regulating a nominal input voltage and powering the receiver and the transponder. A protection circuit is responsive to an injected input voltage and configured to clamp the injected (high level) input voltage at a predetermined maximum voltage.Type: GrantFiled: May 18, 2005Date of Patent: March 31, 2009Assignee: LoJack Operating Company LPInventors: Frank Romano, Sampath Krishna, Son Nguyen, Jesse Rhodes, Philip Grahame Crewe, Daniel Jonathan Finchley Cletheroe, Mark Marsden, Steven Walter Greendale, Nigel James Watson, Ian Christopher Stroud, Timothy David Howe, Gerard Edward Smith, Colin Richard Smithers
