  • Patent number: 11170480
    Abstract: The present invention is directed to systems and methods for generating virtually averaged optical coherence tomography (Oct.) images. An illustrative method can include receiving an image, identifying a first voxel of the image, and selecting a plurality of local voxels of the image. Each of the plurality of local voxels is within a defined region of the first voxel. The values of the plurality of local voxels can indicate an appearance of the local voxels in the image.

  • Patent number: 10575723
    Abstract: The present disclosure describes systems and method for generating surgical maps that provide a surgeon with information regarding the placement of features of interest. More particularly, the system is configured to display optical coherence tomography (OCT) images to a medical professional. The medical professional can select anatomical features, biomarkers, and other features of interest within each of the OCT images. The system can then translate the location of the features of interest within the OCT images to an en face image to generate a map of the features that the medical professional can use for surgical guidance.

  • Patent number: 9844315
    Abstract: The present disclosure is directed to systems and methods for normalizing an image of an eye among multiple optical coherence tomography (OCT) devices. The system can receive an OCT image and generate a normalized OCT image. The system is configured to normalize a sample density of the received image, normalize an amount of noise using a suitable noise reduction technique, normalize a distribution of signal amplitudes of the image, and then normalize a signal quality of the image. The resulting normalized image of the eye can then be used in the comparison among OCT images taken from multiple OCT devices.

  • Publication number: 20160273746
    Abstract: A lighting assembly for a ladder. The assembly has a lighting unit and a mount. The lighting unit has a housing, a controller, a LED group, and a user input device. The controller is signal connected to the user input device and the LED group. The LED group has a plurality of LEDs. The mount is connected to the lighting unit. One mount has a ladder rung receiver and a locking arm. The locking arm is movable between an open position to allow a ladder rung to be received in the run receiver and at least one closed position to secure the ladder run in the rung receiver. Another mount has a toggle anchor for engaging a ladder side rail channel.

  • Patent number: 8566384
    Abstract: Systems and methods are provided for efficiently counting detected events via a multiplicative group counter. An equivalent class polynomial congruent with a first of a plurality of elements comprising a multiplicative group is represented as a series of binary values. The represented polynomial is subjected to a state transition function as each event is detected, such that the series of binary values is altered to represent a new equivalent class polynomial congruent with a second of the plurality of elements of a multiplicative group. The series of binary values is decoded to determine a number of detected events recorded by the counter.
