  • 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.

  • Patent number: 9328499
    Abstract: An object of this invention is to provide an improved means of water treatment effectiveness. The invention strips floating and sinking particulates from flowing water with netting and inclined settling cells, which are arranged in an overlapping fashion to save treatment space. The effluent invert is virtually level with the influent invert to minimize pressure loss. The device pre-treats water for further treatment by filtering methods and among other application is ideally suited for applications where low depth profile treatment is beneficial or required.

  • Patent number: 9158805
    Abstract: Techniques are described for enabling or suspending access to one or more datastores based on a determined quality of the stored data. The datastores may use relational or non-relational formats. User-specified rules may be applied to statistically determine the data quality of at least a portion of the data in the datastore. The rules may perform statistical tests on the data, such as determining whether an amount of stored data is within a margin of a historical average, whether a number of records storing particular data is within a historical average, and so forth. Based on the rules, a flag may be set to indicate the determined data quality. Access to the data may be based on the value of the flag.

  • 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: 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.

  • Patent number: 6898940
    Abstract: A medium and high pressure pump systems supplies a cryogenic fluid from a storage tank. The system comprises a pump that is operable to pump cryogenic liquid or a mixture of cryogenic liquid and vapor. The pump preferably comprises an inducer with at least two chambers and means for recycling excess fluid within the inducer instead of returning excess fluid to the storage tank. The reciprocating pump is preferably double acting such that fluid is discharged from the pump during both extension and retraction strokes.

  • Patent number: 6659730
    Abstract: A method and apparatus is provided for supplying both cryogenic liquid and vapor from a storage tank to a pump to reduce the need for venting. The pump is operable to pump cryogenic liquid or a mixture of liquid and vapor. Different operating modes are selectable to control mass flow rate through the pump. With one operating mode a high flow rate is achieved by supplying only cryogenic liquid to the pump. By selecting another operating mode, a lower mass flow rate is achieved by simultaneously supplying liquid and vapor from the storage tank to the pump. The pump preferably has an inducer with at least two chambers and valves for recycling excess fluid within the inducer instead of returning it to the storage tank. The reciprocating pump is preferably double acting such that fluid is discharged from the pump during both extension and retraction strokes.

  • Publication number: 20020085921
    Abstract: A medium and high pressure pump systems supplies a cryogenic fluid from a storage tank and methods of operating such systems to remove both liquid and vapor from the storage tank to reduce the need for venting. The system comprises a pump that is operable to pump cryogenic liquid or a mixture of cryogenic liquid and vapor. In accordance with the method, mass flow rate through the pump is controlled by selecting one of at least two operating modes. In a first operating mode a high flow rate is achieved by supplying cryogenic liquid to the pump from the storage tank to substantially fill a compression chamber within the pump with liquid. In a second operating mode, a lower mass flow rate is achieved by selectively simultaneously supplying liquid and vapor from the storage tank to the pump, with the vapor fraction being higher in the second operating mode compared to the first operating mode.

  • Patent number: 6062995
    Abstract: The invention relates to an improved joint assembly comprising a deforming element that is compressed to secure a first member into the recess of a second member. Preferably the deforming element comprises angular projections and is made from a relatively soft material which allows for its deformation. The joint of the invention has the advantage of not requiring any heat or tool and is particularly useful for attaching a hockey stick blade to a hockey stick handle without the need of adhesives or other types of mechanical connectors. The invention also relates to a hockey stick blade and to a hockey stick incorporating the deforming element of the present invention.
