  • Patent number: 12164837
    Abstract: The present disclosure relates to graded electrodes for an electric battery cell, and to methods of designing and manufacturing such electrodes. Example embodiments include a method of designing an electrode for an electric battery cell, the electrode comprising a compound mixture of an electrochemically active material, an electrically conductive material and a binding material, the method comprising: applying a model for an electrochemical response of the electric battery cell; and optimising parameters of the model to maximise one or more of an energy density, power density, battery health and thermal response of the electric battery cell.

  • Patent number: 10062162
    Abstract: The present disclosure describes a system and method to segment optical coherence tomography (OCT) images. The present system uses a hybrid method that employs both Bayesian level sets (BLS) and graph-based segmentation algorithms. The system first identifies retinal tissue within an OCT image using the BLS algorithms. The identified retinal tissue is then further segmented using the graph-based segmentation algorithms.

  • Publication number: 20170105616
    Abstract: The present disclosure describes systems and methods to select fovea containing optical coherence tomography (OCT) images. The systems and methods described herein receive a plurality of OCT images. The portion of the OCT images are selected for further processing, where a line tracing the border between the retina and non-retina tissue is generated. A difference of the line is generated. Candidate OCT images are then generated responsive to the generated difference line. The lowest point among each difference lines generated for each of the OCT images is identified, and the OCT image to which the lowest point corresponds is identified as the fovea containing OCT image.

  • Publication number: 20060285600
    Abstract: The channel estimation technique employs a set of pilot tones to determine channel state information. Because some of the pilot tones contained in the OFDM symbols may be missing after transmission, the disclosed technique employs a set of known pilot tones to compute an estimate of the channel impulse response, which may exhibit a level of distortion. Non-zero terms of the estimated channel impulse response that fall outside of a prescribed time window are regarded as artifacts of a set of missing or unknown pilot tones. Information relating to the known pilot tones and the artifacts of the unknown pilot tones are employed for mathematically reconstructing and deriving values of the unknown tones. Then, the values of the known pilot tones and the derived values of the unknown pilot tones are employed to recompute the channel impulse response, thereby obtaining the channel estimate with a reduced level of distortion.

  • Publication number: 20060163040
    Abstract: The invention is related to drive units for conveyor belts. A flexible rider connected to the belt includes a gear for meshing with a gear of the rotable driver. The meshing of the gears allows the conveyor belt to be pulled about the conveyor.

  • Publication number: 20060144679
    Abstract: The present invention is related to an adjustable finger guard or shield for a conveyor. The housing's slide can include the combination of a plate, one or more connectors and a rotable bearing's housing. Moving the slide from a first direction to a second directions alters the position of the shaft of the conveying drum driving the conveyor belt.

  • Publication number: 20060108207
    Abstract: The present invention is related to quick release holders that grip the beading of a conveyor belt. Due to a holder's unique structure, without the use of tools, the holder can manually be opened to release the beading and the conveyor belt. Conversely, without the use of tools, the holder can also be manually closed to secure the beading.
