Patent number: 9684071Abstract: An apparatus is disclosed for a spaceborne or aerial platform having a frequency demultiplexer for frequency demultiplexing a signal corresponding to a range line or an azimuth line of SAR data, and including information about a plurality of target points, into a plurality of frequency channels, and a compression device for performing compression on each frequency channel, each frequency channel signal having information about the same target points. The frequency demultiplexer and the compression device can be implemented in hardware. The apparatus may be used for either or both of the range compression and the azimuth compression of a SAR arrangement on board a spaceborne or aerial platform and the SAR arrangement may generate a plurality of sub-images corresponding to the frequency channels from the SAR raw data. The sub-images may be combined by averaging in order to reduce the volume of memory required to store the SAR data.Type: GrantFiled: March 9, 2012Date of Patent: June 20, 2017Assignee: ASTRIUM LIMITEDInventor: Alexander Walker Wishart

Patent number: 9465115Abstract: An apparatus is disclosed for processing a sequence of samples of a received signal R reflected by a target surface and having a delay and a frequency shift relative to a reference signal D to obtain a delay Doppler map for the reflected signal. A first correlation module can obtain partial correlations z(n?, k) between samples corresponding to the reflected signal R and a samples corresponding to the reference signal D, across a set of delays. An inverse discrete fourier transform (DFT) of a sequence of samples can be derived from at least DFTs of a first reflected signal sequence and second reference signal sequence.Type: GrantFiled: June 14, 2013Date of Patent: October 11, 2016Assignee: AIRBUS DEFENCE AND SPACE LIMITEDInventor: Alexander Walker Wishart

Patent number: 9408143Abstract: User activity on a mobile device is monitored and collected, and a resource usage model is constructed. The resource usage model describes a set of contexts in which the mobile device, and is the basis for determining a first exhaustion point for a resource. Based on the monitored activity, a prediction of a second exhaustion point for the resource time is made. If the second exhaustion point is prior to the first exhaustion point, usage of the resource is reduced.Type: GrantFiled: November 27, 2013Date of Patent: August 2, 2016Assignee: Lookout, Inc.Inventors: Samuel Alexander Walker, Ayan Kanti Mandal, Devesh Senapati, Kevin Patrick Mahaffey, David Luke Richardson, Brian James Buck

Patent number: 8687210Abstract: Disclosed are methods and apparatus for accessing data from electronic documents stored as print streams are disclosed. In one embodiment, an electronic document conforming to one of a plurality of print formats is obtained. The electronic document is parsed according to the one of the plurality of print formats to generate an intermediate data structure conforming to an intermediate format such that the electronic document is converted to the intermediate format, wherein the intermediate format is different from the plurality of print formats. One or more rules are applied to obtain data for a plurality of regions of the electronic document from the intermediate data structure. The data for the plurality of regions of the electronic document that has been obtained from the intermediate data structure is stored or provided, thereby enabling a report to be generated using at least a portion of the data for the plurality of regions that has been stored or provided.Type: GrantFiled: May 13, 2011Date of Patent: April 1, 2014Assignee: Actuate CorporationInventors: Brian Sue, Paul Alexander Walker, William Davis, William Morris Guthrie, Jr., Jason Bryant Weathersby, Richard James Seabright

Patent number: 8655307Abstract: Security is enhanced for a user of a mobile device by monitoring and controlling resource usage. Usage information associated with a mobile device is collected. The collected information is used to build a usage model for a user of the mobile device that describes a set of contexts in which the mobile device is used. User activity on the device is monitored and the model is consulted to determine a first time after which it will be acceptable for a battery of the mobile device to fall below a threshold charge level. Based on the monitored activity, a prediction of a second time is made for when the battery will fall below the threshold charge level. If the second time is before or a predetermined amount of time before the first time, usage of the battery is reduced, else, usage of the battery is not reduced.Type: GrantFiled: November 27, 2012Date of Patent: February 18, 2014Assignee: Lookout, Inc.Inventors: Samuel Alexander Walker, Ayan Kanti Mandal, Devesh Senapati, Kevin Patrick Mahaffey, David Luke Richardson, Brian James Buck

Publication number: 20070174086Abstract: A system and method for identifying safety concerns regarding a drug identify a first group of patients that have received the drug from a database of healthcare claims and extract one or more medical events that the first group of patients have experienced from the database. The system and method also identify a second group of patients that have received a comparator drug in the database and extract one or more medical events that the second group of patients have experienced. The medical events of the first group are compared to the medical events of the second group to determine at least one common occurrence therebetween. The common occurrence(s) is then filtered based upon one or more user defined outcomes, each including at least one diagnosis, procedure or therapeutic classification; non-medical criteria; and/or patient laboratory test data.Type: ApplicationFiled: November 20, 2006Publication date: July 26, 2007Inventor: Alexander Walker
