Abstract: Oxides formed during annealing of stainless steel strip are removed with abrasive brushes, in lieu of acid or molten salt based pickling. In some embodiments, the stainless steel strip is treated with a rare earth element or a related transition metal before annealing, and then brushed after annealing to remove any oxides. The selection of brushes can impart a finished appearance to conventionally polished stainless steel.

Abstract: One embodiment provides a system that facilitates efficient collection of training data. During operation, the system obtains, by a recording device, a first image of a physical object in a scene which is associated with a three-dimensional (3D) world coordinate frame. The system marks, on the first image, a plurality of vertices associated with the physical object, wherein a vertex has 3D coordinates based on the 3D world coordinate frame. The system obtains a plurality of second images of the physical object in the scene while changing one or more characteristics of the scene. The system projects the marked vertices on to a respective second image to indicate a two-dimensional (2D) bounding area associated with the physical object.

Abstract: Embodiments described herein provide a system for facilitating dynamic assistance to a user in an augmented reality (AR) environment of an AR device. During operation, the system detects a first element of an object using an object detector, wherein the object is associated with a task and the first element is associated with a step of the task. The system then determines an orientation and an alignment of the first element in the physical world of the user, and an overlay for the first element. The overlay can distinctly highlight one or more regions of the first element and indicate how the first element fits in the object. The system then applies the overlay to the one or more regions of the first element at the determined orientation in the AR environment.

Abstract: One embodiment provides a method for facilitating real-world interaction with virtual reality. During operation, the system receives, by a computing device from a virtual reality device associated with a user, instructions to configure physical components, wherein for a first physical component at a first location, the instructions indicate a type and an orientation, and wherein for a second physical component located at a second location, the instructions indicate a type, a length of extension, and an angle. The system executes, by a pose-adjusting unit, the instructions, which involves: physically moving the first physical component to the indicated orientation at the first location; physically extending the second physical component from the second location by the indicated length; and physically rotating the extended second physical component by the indicated angle. The system renders, on the virtual reality device, the configured physical components.

Abstract: One embodiment provides a system that facilitates efficient collection of training data for training an image-detection artificial intelligence (AI) engine. During operation, the system obtains a three-dimensional (3D) model of a physical object placed in a scene, generates a virtual object corresponding to the physical object based on the 3D model, and substantially superimposes, in a view of an augmented reality (AR) camera, the virtual object over the physical object. The system can further configure the AR camera to capture a physical image comprising the physical object in the scene and a corresponding AR image comprising the virtual object superimposed over the physical object, and create an annotation for the physical image based on the AR image.

In one aspect, a device includes memory having computer-readable instructions stored therein and one or more processors. The one or more processors are configured to execute the computer-readable instructions to receive video data of traffic flowing through an intersection; based on the video data, determine if a rate of flow of the traffic is greater than a predetermined threshold; determine a correlation between the rate of flow and one of a plurality of object types if the rate of flow is not greater than the predetermined threshold; determine a rule for controlling the traffic flow through the intersection based on the correlation; and cause adjustments to traffic control settings of a traffic light at the intersection based on the rule.

Abstract: The present disclosure is directed to methods and apparatus for providing directions to user devices that belong to pedestrians or to individuals traveling on pedestrian pathways. Pedestrians or other users of user devices wishing to travel along pedestrian pathways toward a destination may be provided instructions according to a criterion, a basic assumption, or a rule. While commonly such criteria may relate to providing individuals with directions to walk from a current location to a specified destination in a minimal time, methods and apparatus consistent with the present disclosure may also allow for a user to specify other rules or criteria that are consistent with one or more objectives or parameters specified by that user. To accomplish this, information may be received from user devices and instructions may be sent to those user devices as users of those user devices progress toward respective destinations.

Abstract: A current or forecasted weather condition at an intersection or roadway may be identified using cameras and/or other weather sensors connected with traffic infrastructure installed at the intersection or roadway. Adverse traffic events typically associated with weather conditions of the same type as the identified weather condition may be determined, for example based on historical records of correlations between weather and traffic. The traffic infrastructure may adjust an option, for example by adjusting traffic signal timings, to mitigate the adverse traffic event in response to identifying the weather condition.

Abstract: A camera captures a reference image during a first environmental condition. Environmental information from sensors or a network source identifies a second environmental condition, during which the camera captures an environment-affected image. An environmental effect affecting the environment-affected image is identified based on a difference between the reference image and the environment-affected image. A component that mitigates the environmental effect is identified. For example, a heating element may be identified to mitigate ice or condensation. The identified component is automatically activated to mitigate the environmental effect on future images captured by the camera during the second environmental condition.

Abstract: A camera whose field of view includes an intersection of thoroughfares captures images and/or video of the intersection. Based on the captured images and/or video, a computer system surveys vehicular traffic through the intersection visible and defines both a risk zone of the intersection and a safe zone associated with the intersection. The computer system identifies that an at-risk vehicle is present in the risk zone and automatically modifying a timing of a traffic signal indicator to allow the at-risk vehicle to pass through the risk zone into the safe zone, for example by extending a green or yellow light.
