Title: Memory and processor hierarchy to improve power efficiency
Inventor: GIEFERS HEINER
IPC: G06F15/82
Filed: 2014-09-16
Abstract: A data processing system has data processing functionality in an execution unit, which is integrated into the memory system. An access processor sends data stored in the memory to the execution unit for processing. The access processor may send a tag with the data, identifying whether it is an operand or a configuration. The access processor uses the length of time taken to carry out the data processing operations in order to reserve time slots for the execution unit to write its results back into the memory. The access unit may send program information to the execution unit in order to configure it. The execution unit may be implemented as a field programmable gate array (FPGA). The memory may have a more than one execution unit and the some execution units may be more tightly coupled to the memory than others.

Title: Hybrid energy storage devices including support filaments
Inventor: ROJESKI RONALD
IPC: H01M10/0525
Filed: 2013-07-03
Abstract: A novel hybrid lithium-ion anode material based on coaxially coated Si shells on carbon nanofibers (CNF). The unique cup-stacking graphitic microstructure makes the CNFs an effective Li+ intercalation medium. Highly reversible Li+ intercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. Addition of surface effect dominant sites in close proximity to the intercalation medium results in a hybrid device that includes advantages of both batteries and capacitors.

Title: A video signal caption system and method for advertising
Inventor: Christopher Hackett
IPC: H04N21/8405
Filed: 2014-11-07
Abstract: A method of processing and storing caption (subtitle) data included in a received video signal, and communicating when it is detected that the video contains caption data corresponding to stored caption data. The advertising method then selects and configures advertisements to display. Subtitle information may be closed captions or open captions and may be associated with descriptors relating to the video, which may be a television broadcast signal. Portions of caption information may be input to a hash function to generate a hash code that is included in the stored caption data. Caption matching may include comparing hash codes in video with stored hash codes. Caption data may include next/previous caption frames, TV channel, time stamp and descriptor information. Content optimisation may select content to display on a users webpage, search engine or user interface, such as a smartphone, tablet or smart television, based on the received descriptor(s). For example, when a TV programme shows a particular make/model of car, the encoded programme subtitle information may be used to display a targeted advertisement for the same or competing model of car to a second screen portable electronic device.
