Patent number: 9161250Abstract: Satellite scanning is an example of scanning a transmission spectrum, which relates to identifying satellite channels within a satellite broadcast spectrum. Rather than scanning the entire transmission spectrum at each possible combination of frequency and symbol rate, spectrum analysis may be performed over the transmission spectrum in order to determine an estimate of signal strength over the transmission spectrum in the frequency domain. The estimate of signal strength in the frequency domain can be used to identify candidate transmission channels (e.g. at frequencies where the signal strength is high). A targeted scan of the transmission spectrum can then be performed based on the identified candidate transmission in order to identify the transmission channels.Type: GrantFiled: October 2, 2014Date of Patent: October 13, 2015Assignee: Imagination Technologies LimitedInventors: Matt Gilbert, Adrian John Anderson, Christopher Owen

Patent number: 9110049Abstract: A use composition monitor determines the concentration of peracid and/or peroxide in a use composition using a kinetic assay procedure. A sample mixture containing a sample of the use composition, a diluent and at least one reagent is prepared and analyzed using, for example, an optical detector. A reduced-turbulence optical detector can be used to improve collected response data. A reduced-turbulence optical detector can include a cell body disposed about a length of transparent tubing. The cell body positions one or more emitter/receiver pairs about the transparent tubing. Thus, tube junctions are eliminated and sample flow within the tube is substantially turbulence free.Type: GrantFiled: October 11, 2013Date of Patent: August 18, 2015Assignee: Ecolab USA Inc.Inventors: Eugene Tokhtuev, Christopher Owen, Anna Pilipchenko, Paul Schilling, Daniel Kamben

Publication number: 20150067440Abstract: Methods and apparatus for decoding LDPC codes are described. An LDPC code may be represented as a Tanner graph comprising bit nodes and check nodes and connections between them. In an embodiment, a configurable LDPC decoder, which supports many different LDPC codes having any sub-matrix size, comprises several independently addressable memories which are used to store soft decision data for each bit node. The decoder further comprises a number, P, of check node processing systems which generate updated soft decision data. The updated values are then passed back to the memories via a shuffling system. If the number of check nodes processed in parallel by the check node processing systems is PCNB (where P?PCNB) and the soft decision data for a bit node is of word size q bits, the total width of the independently addressable memories is larger than PCNB*q bits.Type: ApplicationFiled: July 24, 2014Publication date: March 5, 2015Inventors: Christopher Owen, Adrian John Anderson

Patent number: 8730701Abstract: An H-bridge control circuit comprises an input stage, comparator stage, inverter stage. The operation of the H-bridge can be controlled by a single analog input signal provided by a feedback stage. Shoot-through protection is provided for the H-bridge circuit through the inclusion of a dead gap determined by inputs to the comparator stage. The dead gap can be adjusted, allowing for adjustment of the precision operation of the load. The H-bridge can be used to drive a bi-directional load such as, for example, a Peltier conditioner.Type: GrantFiled: February 12, 2009Date of Patent: May 20, 2014Assignee: Ecolab USA Inc.Inventors: Anatoly Skirda, Eugene Tokhtuev, Christopher Owen, Viktor Slobodyan
