Abstract: A method to provide visual feedback for gazed-based user-interface navigation includes presenting, on a display, a first image representing a digital object available for user interaction, recognizing a user gaze axis, and computing a point of intersection of the user gaze axis through the first image. An offset distance between the point of intersection and a reference position of the first image then recognized, and a second image is presented on the display. The second image is presented displaced from the point of intersection by an amount dependent on the offset distance.

Abstract: A method for providing electrical system status information to a mobile device user is presented. The method comprises receiving a request for target area electrical system status information from a mobile device, determining the pose of the mobile interface device relative to the target area, obtaining target area electrical system status information for a target electrical system at least partially disposed within the target area, and assembling AR electrical system status information for transmission to and display on the mobile interface device. The AR electrical system status information is assembled using the target area electrical system status information and is configured for viewing in conjunction with a real-time view of the target area captured by the mobile interface device. The AR electrical system status information is then transmitted to the mobile interface device.

Abstract: The present invention provides actuation mechanisms that incorporate a transmission assembly that allows the mechanisms to cause actuation of workpieces according to a plurality of transmission modes (e.g., at least one forward transmission mode and at least one reverse transmission mode) on demand. Motion, direction, and/or force can be controlled by selecting the corresponding transmission mode. The mechanisms preferably are trigger-actuated by hand (i.e., manually) to cause movement of a workpiece in a desired direction. Desired directions can be linear or nonlinear. The same hand used for trigger action can also be used to change transmission modes in many modes of practice, even while using substantially the same grip used for trigger actuation. In other instances, actuation can be automated rather than manual. Preferably, both actuation and witching among transmission modes can be accomplished with one hand, even while maintaining substantially the same grip that is used for actuation.

Abstract: The present disclosure provides approaches to simulating depth of field. In some implementations, an optimal scan distance of a camera from a subject in a physical environment is determined for a scan of the subject by the camera. A blur level is iteratively updated to correspond to a proximity of the camera to the determined optimal scan distance as the proximity changes during the scan. For each update to the blur level from the iteratively updating, an image comprising a three-dimensional (3D) model of the physical environment depicted at the updated blur level is generated on a user device associated with the scan.

Abstract: A device and method for producing a reformate fuel from a hydrocarbon gas source. The invention enables the conversion of a dilute hydrocarbon gas into a more easily consumable reformate fuel. Gases having low concentrations of hydrocarbons are concentrated using a concentrator into a gaseous or liquid concentrated VOC fuel. The concentrated VOC fuel is then converted into a reformate using a reformer. The reformate is more easily consumed by an energy conversion device such as a combustion engine, fuel cell, sterling engine or similar device that converts chemical energy into kinetic or electrical energy. The reformer enables complex hydrocarbon fuels that are not normally suitable for use in an energy conversion device to be converted into a reformate. The reformate may be directly supplied into the energy conversion device.
