Abstract: Disclosed herein are methods, systems, and computer-readable media for generating an image corresponding to a text input. In an embodiment, operations may include accessing a text description and inputting the text description into a text encoder. The operations may include receiving, from the text encoder, a text embedding, and inputting at least one of the text description or the text embedding into a first sub-model configured to generate, based on at least one of the text description or the text embedding, a corresponding image embedding. The operations may include inputting at least one of the text description or the corresponding image embedding, generated by the first sub-model, into a second sub-model configured to generate, based on at least one of the text description or the corresponding image embedding, an output image. The operations may include making the output image, generated by the first second sub-model, accessible to a device.

Abstract: Secure user authentication using a OTP involve pre-storing an application on a first device for generating a valid OTP for the user responsive to receiving entry of a valid PIN, no part of the valid PIN is stored on the first device and pre-storing on a back-end server the valid PIN and a valid shared secret for the user. Upon receiving entry of a purported PIN, a purported shared secret is dynamically synthesized on the first device by the application based on the purported PIN and a purported OTP is generated on the first device. When entry of the purported OTP is received by the server in an attempt to log on the server from a second device, the server cryptographically calculates a window of OTPs, and logs on to the server from the second device is allowed if the calculated window of OTPs corresponds to the received OTP.

Abstract: The present invention provides improved optical elements, such as light diffusing films, plates, and lenses, which can be used in light-emitting devices, such as light fixtures to control the distribution of light projected onto illuminated objects, such as walls, sculptures, and landscaping. Compared to traditional light scattering films, plates or lenses, improvements in illuminance uniformity, optical throw, system efficacy, and aesthetic appearance are achieved. Embodiments of the invention utilize region(s) of volumetric asymmetric diffusion that allow a partial quantity of light to be transmitted without significant scattering in order to improve optical throw and illuminance uniformity. Embodiments can also eliminate hotspot and thus improve the illuminated uniformity.

Abstract: A method for providing mutual exclusion at a single data element level for use in embedded systems. Entries for tasks that are currently holding a resource are stored in a hold list. Entries for tasks that are not currently executing and are waiting to be freed are stored in a wait list. A single mutual exclusion semaphore flags any request to access a resource.

Abstract: A method and architecture having components for performing a method comprising the steps of: forming a simple bi-directional communication link between each of the clients and a server; and, transmitting along the communication link at least one of two kinds of messages comprising a first message which is a synchronous query/response, and a second message which is an asynchronous subscription based event notification, to allow arbitrary data structures to be rendered into a standard communication format.
