Abstract: Techniques are disclosed for provisioning and managing a virtual edge device that is configured to emulate a physical edge device that executes within an isolated computing environment. The isolated computing environment may be separate from a centralized cloud computing environment that provides a plurality of services for executing customer workloads. In one example, a computer system receives a request to provision a virtual edge device. The computer system identifies a physical computing device to be provisioned as the virtual edge device based on the request. The computer system generates a set of data containers that containerizes a set of services configured to execute subsequent workloads, and then the system provisions the physical computing system with the set of data containers. In response to the customer request, the computer system provides a user interface operable for accessing and managing the virtual edge device.

Abstract: Provided is a touch-screen system that employs infrared illuminators and detectors to determine where an object or person touches a translucent screen. A visual image is projected onto the translucent screen by means of a projector placed on the back side of the screen opposite the user. Infrared illuminators are placed on the front side of the translucent screen at oblique angles to the screen. When a user touches the screen each of the infrared illuminators is shadowed from the screen to a certain degree, depending upon the shape of the object placed upon the screen. By determining where on the screen the shadows cast by the object or person overlap, a computing device calculates where the object or person is touching the screen In an alternative embodiment, controlled ambient light rather than infrared illuminators is employed. Also provided is a calibration method for the system.
