20110004787 | SELF-REPAIRING ELECTRONIC DATA SYSTEM - An array of logic devices capable of self-determining the program, inputs and outputs from configuration information provided by its nearest neighbours. The rules used by each device to self-determine its behaviour are identical to those of every other device in the array. This facilitates the development of robust array configurations and robust behaviour of the device as a whole. This system's logic devices utilize three shift-registers, two are programmed before operation, the third is programmed on-the-fly by the other two. This facilitates a fast response to changes in the performance of the array in the event of partial dynamic or static failures of the array. An iterative design algorithm for the array ensures optimum use of the resources of the array. | 01-06-2011 |

20130120813 | HOLOGRAPHY - An iterative algorithm for hologram design with multiple output image planes arranged in close proximity to create continuous patterns within an imaging volume is disclosed. These may then be used for photolithography on 3D surfaces, or for generation of holograms for use in consumer devices. | 05-16-2013 |

20110288695 | CONTROL INTERFACE FOR UNMANNED VEHICLES - An unmanned vehicle system containing one or more vehicles equipped with an autonomous control system. Each vehicle is of navigating on its own when provided with goals. A user is capable of sending and receiving goals from the autonomous control system via a communication link. A unified display interface displays information about the system and accepts commands from the user. The display interface in question is modeless and has a minimum of clutter and distractions. The form of this display interface is that of a set of screens, each of which is able to receive touch inputs from the user. The user is able to monitor and control individual vehicles or the entirety of the UVS solely through their use of a standard touchscreen with no additional peripherals. | 11-24-2011 |

20100036583 | Method and apparatus for controlling an engine capable of operating on more than one type of fuel - A control system for an engine capable of operating on more than one type of fuel includes an engine control unit that determines a default fuel volume to be injected into the engine based on relevant engine parameters and characteristics of a default fuel type. A default mass fuel flow rate is derived from the default fuel volume and relevant engine parameters. The actual mass fuel flow rate into the engine is inferred from the mass air flow rate into the engine and the exhaust gas air-to-fuel ratio, which is determined using a wide range oxygen sensor. A fuel correction factor is calculated from the default mass fuel flow rate and the inferred mass fuel flow rate. The fuel correction factor is used to increment or decrement the default fuel volume in a subsequent fuel injection cycle thereby incrementing or decrementing the inferred mass fuel flow rate toward the default mass fuel flow rate. | 02-11-2010 |
