Abstract: A stackable, non-contact device for operating elevator buttons is described. The non-contact device includes a servo mechanism with a dual-arm configured to press either of two elevator buttons. Two proximity sensors are configured to register the approach of a finger touch of either proximity sensor, which commands the servo mechanism to press the corresponding elevator button. The stackable, non-contact device includes a microcontroller configured to receive near field communications from a mobile application, which includes commands for pressing a specific elevator button.

Abstract: An apparatus for generating an inspection schedule includes one or more processors configured to: receive one or more schedule requests comprising inspector features, establishment features, and penalty features; generate inspector information for an inspector model based on the inspector features; generate establishment information, comprising a probability of imposing a penalty on an establishment of the establishment features, for an establishment model based on the establishment features and the penalty features; and generate, for an inspector of the inspector features using a violation model, the inspection schedule based on the inspector information and the establishment information.

Abstract: Provided is a method and/or system that facilitates offline sharing and verifying digital identity claims among NFC enabled portable smart devices that are enabled by enabling applications. The enabled portable smart-devices store, verify and share identity, peer to peer and offline. Each identity claim is digitally signed by an identity issuing authority, and the claim can be verified to reliably detect tampering of the claim and thus brings trust in the process of claim sharing and verifying the identity/credentials embodied in the claim. Either Blockchain or non-blockchain, as the backend system of the method/system, can be used, via an inter-operable middleware layer, for onboarding claim holders, claim verifiers, and claim issuers, and for creating/issuing, for managing digital identity claims. NFC, as the communication protocol, facilitates secure data sharing among the NFC-enabled devices.

Abstract: A method, system, and computer readable medium are described to capture, detect, and recognize faces using machine learning and a single-stage face detector. A method to determine live faces from spoof 2D and spoof 3D images using a liveness score as well as a method to classify faces using machine learning deep convolutional neural networks is also described.

Abstract: Scene-referred metadata comprising correspondence relationships between coded values used in generated images and reference values defined independent of any specific image may be provided as a part of image metadata for the generated images. Downstream image processing devices or image rendering devices may use the scene-referred metadata to perform image processing or rendering operations. When coded values of input images are altered in corresponding output images, the scene-referred metadata may be updated with new coded values used in the output images. Reference values refer to reference color values or reference gray levels. Coded values refer to color values or gray levels coded in pixels or sub-pixels of one or more images.

Abstract: An apparatus and a method for displaying a panoramic image using a look-up table (LUT) are disclosed, including generating an LUT may include determining first geometric correction information to transform an input domain pixel coordinate system of an input image to a panorama domain pixel coordinate system of a panoramic image, determining second geometric correction information to transform an output domain pixel coordinate system of an output image of the panoramic image to the panorama domain pixel coordinate system of the panoramic image, determining third geometric correction information to transform the output domain pixel coordinate system of the output image to the input domain pixel coordinate system of the input image based on the first geometric correction information and second geometric correction information, and generating an LUT that maps the output domain pixel coordinate system of the output image to the input domain pixel coordinate system of the input image.

Abstract: Tooth whitening device for whitening teeth using sonochemistry includes a body, and an ultrasonic transducer provided in the body. The ultrasonic transducer is configured for producing ultrasonic waves in the range of 20-100 kHz, and good results have been achieved with ultrasonic waves at a frequency of 40 kHz. There is an ultrasonic horn provided on the body, and the ultrasonic horn is operatively connected with the ultrasonic transducer. A liquid retaining element is provided on the ultrasonic horn, and the liquid retaining element is configured for retaining a liquid tooth whitening composition against a user's teeth. The liquid retaining element may be a sponge or a replaceable pad, such as a foam pad.

Abstract: In a system that includes two or more computing systems connected to a computer network, a network control and synchronization (NetSync) application controls the in-sync playback of media files across different computing systems in the network, where each computing system is playing a local version of a media file using a local instance of a Media player. The NetSync application receives status messages from all Media players and controls the playback of all media files by sending them playback commands based on the received status messages, so that video playback among the players is in sync with a Master Media player. Alternatively, media playback across all Media players is based on user-entered playback commands, such as Play, Pause, Stop, and the like, entered using either the NetSync application interface or NetSync command scripts.

Abstract: Provided is a geometric correction apparatus and method based on a recursive Bezier patch sub-division. A geometric correction method may include: receiving, from a camera, a first image that is obtained by photographing a black screen that is projected by a projector onto a projection surface; receiving, from the camera, a second image that is obtained by photographing a predetermined pattern that is projected by the projector onto the projection screen; generating a third image by subtracting the first image from the second image; and performing geometric correction with respect to the predetermined pattern to correct a distortion between the predetermined pattern and the third image.

Abstract: An apparatus and a method for correcting colors of an image projection device are provided. The method includes: acquiring a photographed image by photographing a sample image projected on projection surface; generating input-output color information for n regions, based on color values of a block in the sample image and corresponding color values of the block in the photographed image; selecting one of the n regions of photographed images as a reference region; generating look-up tables (LUTs) for non-reference regions, based on the reference region and the input and output color information; and correcting colors of input images to be projected by the image projection device using the look-up tables, thereby minimizing color difference of the input images on the projection surface for both intra and inter projection device color correction while simplifying the correction procedure.
