Abstract: A system and method for managing inventory for an electronic raffle is provided. The system may include an inventory database to store inventory data for one or more items to be sold via the electronic raffle, wherein the inventory data includes in-store inventory data and online inventory data, a mobile application configured to generate a raffle entry for the one or more items, a raffle database configured to store the inventory data and one or more raffle entries, and a middleware server configured to update the in-store inventory data stored in the raffle database based on the updated in-store inventory data obtained from the inventory database. The middleware server selects a first round winning raffle entry, transmits a notification to the mobile device associated with the first round winning raffle entry, and initiates a payment process upon determining that the first round winning raffle entry applies to the lightning round.

Abstract: The subject invention pertains to a novel angle-closure detection method for risk assessment of primary angle closure (PAC) or primary angle closure glaucoma (PACG) to inform treatment decisions. According to certain embodiments, a plurality of cross-sectional images of the anterior segment of an eye centered at the pupil with preferably even radial separations are obtained from optical coherence tomography imaging. After identifying the position of scleral spur from the cross-sectional image captured at each angle-location, the anterior chamber angles are analyzed. Each angle-location of the eye is classified as (i) closed angle, (ii) narrow angle, or (iii) open angle. The extents of narrow angles and closed angles among all angle-locations across the 360° radial space are computed. Based on the extents of narrow angles and closed angles, a regression model is applied to compute the risk of PAC/PACG development.

Abstract: Disclosed techniques evaluate the visual field of a patient's eye using deep learning techniques. A computer system obtains a plurality of cross-sectional scan images of a retina captured by an optical coherence tomography (OCT) device. The retina has an inner retinal layer. A retinal optical texture analysis (ROTA) map of the inner retinal layer is generated from the plurality of cross-sectional scan images. The ROTA map includes a plurality of pixels, and each pixel of the ROTA map corresponds to a respective optical texture signature value S providing information about tissue composition and optical density of the inner retinal layer at a respective retinal location. The computer system applies a machine learning model to process the ROTA map of the inner retinal layer to determine visual field sensitivity of the retina.

Abstract: A repaired reinforced concrete structure is provided which includes one or more reinforcing steel bars of cross-sectional area Ax, the one or more reinforcing steel bars having one or more corroded sections of cross-sectional area Ay, wherein Ay is greater than or equal to approximately 0.6 Ax. A reinforced ordinary Portland cement-based repair mortar is positioned directly on the one or more corroded sections of the one or more reinforcing steel bars without the addition of a lapped reinforcing steel bar. The reinforced repair mortar includes at least approximately 1 percent by volume of reinforcing steel fibers such that the reinforced repair mortar restores a strength of a repaired region to greater than approximately 100% of an original strength of the concrete structure in an uncorroded state. The repaired reinforced concrete structure is highly durable, as the repair mortar exhibits an air permeability resistance of greater than 1000 seconds.

Abstract: Methods and systems describe remotely triggering the capture of media data. A navigator device at a server is connected with an operator device over a network, with the operator device being handled by an operator. Streaming media data is received at the server, and concurrently, the incoming streaming media data is analyzed to determine whether a match for one or more predefined visual landmarks can be identified. Upon a determination that a match cannot be identified, instructions are communicated, via the navigator device, for the operator to reposition the operator device. Upon a determination that a match for one or more predefined visual landmarks can be identified, capture of the streaming media data with the visual landmarks is triggered.

Abstract: A user device stores a local application including initial search records and an initial search function. Each initial search record includes an application link that opens an application page and search data that describes the application page. The initial search function is configured to select from the initial search records. The user device executes the local application to request and receive search update data from a remote system. The search update data includes updated search records and an updated search function. The user device updates the initial search records and the initial search function with the updated search records and the updated search function. The user device receives a search query from a requesting application, selects a set of updated search records based on the search query and the updated search function, and provides a response to the requesting application including application links from the set of updated search records.

Abstract: Optical texture analysis of the inner retina, including the retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), or inner plexiform layer (IPL), or a combination of these layers, can be used to detect and quantify RNFL/GCL/IPL abnormalities. From a set of scans of a retina, anterior and posterior boundaries of an inner retinal layer of interest can be determined. Optical density measurements at specific locations on the retina and depths within the layer of interest can be extracted from the scans. From these measurements, a set of optical texture signature values corresponding to different locations can be computed, where the optical texture signature value for a given location provides information about a tissue composition of the inner retinal layer at that location. The texture signature values can provide a topographical map of a retinal layer, which can facilitate detection and quantification of abnormalities.

Abstract: Techniques for a visual disability detection system that employs virtual reality to assess visual performance of a patient based on activities of daily living are described. The virtual reality platform can integrate the testing of different components of visual function based on activities of daily living to provide a direct and clinically relevant measure of the impact of any visual disability on a patient's daily life. By simulating daily tasks for evaluation of visual disability, clinicians can better understand from a patient's perspective how visual impairment affects their daily tasks and quality of life.
