  • Picture encoding and decoding
    Patent number: 9143794
    Abstract: Video is encoded by applying a vertically and horizontally separable transform to provide a block of transform coefficients; and quantizing the transform coefficients. Prior to quantization, a filtering operation is performed on the block of transform coefficients, the filtering operation applying a rotation to pairs of coefficients in the block. Each pair of coefficients may be symmetrically positioned with respect to the leading diagonal of the block.

  • Protocols for visible light communications
    Publication number: 20150071644
    Abstract: The invention relates to the field of IEEE 802.15.4 based networks, and in particular to methods and devices for transmitting and receiving messages in IEEE 802.15.4 based networks. The existing IEEE 802.15.4 standard is further improved and adapted to better fit the properties of a network of lighting devices. The improvements and adaptations of the existing IEEE 802.15.4 standard allow for more flexible addressing. Bits which are indicative of use of address fields and/or whether one or two frame control fields is/are present in the ordered data portions of the message to be transmitted are defined by the device transmitting the message in the IEEE 802.15.4 based network. Existing features of the existing IEEE 802.15.4 standard protocol are retained.

  • Fuel formulations
    Patent number: 8790422
    Abstract: Gasoline fuel formulation having a laminar burning velocity SL which is equal to or below that of isooctane at a pressure of 1 bar, a temperature of 300 K and stoichiometric air/fuel mixture strength. The formulation can be used to reduce pre-ignition in a turbocharged spark ignition engine, in particular when operating with an inlet pressure above 1.5 bar absolute. The formulation can thus also be used to reduce engine damage. The invention also provides a method of preparing a gasoline fuel, by mixing gasoline fuel components to achieve a laminar burning velocity SL for the resultant mixture which is equal to or below that of isooctane at a pressure of 1 bar, a temperature of 300 K and stoichiometric air/fuel mixture strength. It further provides a method for selecting a gasoline fuel for use in a turbocharged spark ignition engine, based on its laminar burning velocity SL.

  • Filtering data flows
    Patent number: 8743687
    Abstract: There is disclosed a method and controller for controlling an information flow in a data transmission system including receiving a plurality of data packets. The method and controller also includes selectively discarding and/or selectively time-shifting the data packets in a predetermined manner to generate a modified information flow. The method and controller also includes selectively discarding and/or selectively time-shifting the data packets of the modified information flow to generate at least one further modified information flow. The further modified information flow may be obtained in a selected one of a plurality of parallel steps.
