Machine learning method that learns to convert 2D video to 3D video from a set of training examples. Uses machine learning to perform any or all of the 2D to 3D conversion steps of identifying and locating objects, masking objects, modeling object depth, generating stereoscopic image pairs, and filling gaps created by pixel displacement for depth effects. Training examples comprise inputs and outputs for the conversion steps. The machine learning system generates transformation functions that generate the outputs from the inputs; these functions may then be used on new 2D videos to automate or semi-automate the conversion process. Operator input may be used to augment the results of the machine learning system. Illustrative representations for conversion data in the training examples include object tags to identify objects and locate their features, Bézier curves to mask object regions, and point clouds or geometric shapes to model object depth.

Method for converting 2D video to 3D video using 3D object models. Embodiments of the invention obtain a 3D object model for one or more objects in a 2D video scene, such as a character. Object models may for example be derived from 3D scanner data; planes, polygons, or surfaces may be fit to this data to generate a 3D model. In each frame in which a modeled object appears, the location and orientation of the 3D model may be determined in the frame, and a depth map for the object may be generated from the model. 3D video may be generated using the depth map. Embodiments may use feature tracking to automatically determine object location and orientation. Embodiments may use rigged 3D models with degrees of freedom to model objects with parts that move relative to one another.

A sun shade for a hard hat includes a piece of flexible material removably and adjustably attached to a hard hat that is stretched to a substantially consistent shape by a piece of springing material. The flexible material may be attached to the hard hat using an elastic band, drawstring, or similar means for attaching. When not in use, the springing material may be removed from the flexible material and stored as a straight piece of material or rolled and stored as a coil. Additionally, the flexible material, such as fabric or soft plastic, may be folded and stored. The flexible material may also include a flap that drapes over the sides and back of the user's neck to provide enhanced protection from direct radiant energy.

The invention is a device that converts a linear input to a rotational output. The invention includes a system of one or more extendable and retractable members that actively change the radius of rotation of weights on the members. The members are connected to a rotatable member for rotation about a non-vertical axis. By actively changing the radius of rotation of a weight, a non-circular path is established for each weight to follow. This path is biased so that, while the weight has the greatest radius of rotation, it also is undergoing a downward stroke. While the weight is undergoing an upward stroke, the radius of rotation is at its minimum. The system thereby utilizes the force of gravity during transitions between maximum and minimum radii to produce a rotational output.

The apparatus and method for releasably joining first and second elements according to the present invention include a retaining member mounted to one of the elements and a reshapeable tube near the retaining member. The reshapeable tube has at least two states, an at least partially collapsed state and an at least partially expanded state. As such, the retaining member joins the elements while the reshapeable tube is in the at least partially collapsed state. Furthermore, the retaining member releases the other element while the reshapeable tube is in the at least partially expanded state, which deflects the retaining member. Thus, because components of the apparatus are not broken during the release of the elements, the amount of constrained or potential energy that is released when the retaining member releases the elements is substantially reduced or eliminated, which protects the elements from being damaged during the release.

Trigger activated tools are provided that have one or more activation lockouts. The activation lockouts include electrical resets, variable position lockouts, mechanical lockouts, shield lockouts, and any combinations thereof.

A motor mounted on a structural support with a pivot at its center line which comprises a cylindrical vessel for holding a fluid in a closed system and in which a buoyant cylinder containing a lighter fluid is allowed to free float so that a cable attached to either end of the buoyant cylinder may be used to transfer energy to a energy storage unit, a crank or a generator. Two moment arms having a weight attached at the exterior end and inside attachably connected to the surface of two drive pistons that operate in pressure tanks which force a compressed gas against the pistons through pre-sequenced automatic activated valves to extend or retract the moment arms at the end of a cycle. The motor then becomes top heavy and rotates 180 degrees by gravity and relocks in place to repeat the cycle.

The bounded area is typically created by a dielectric of various sorts, such as within a dielectric container or properly charged air.

A method of mass spectrometry is disclosed comprising providing a flight region for ions to travel through and a detector or fragmentation device. A potential profile is maintained along the flight region such that ions travel towards the detector or fragmentation device. The potential at which a first length of the flight region is maintained is then changed from a first potential to a second potential whilst at least some ions are travelling within the first length of flight region. The changed potential provides a first potential difference at an exit of the length of flight region, through which the ions are accelerated as they leave the length of flight region. This increases the kinetic energy of the ions prior to them reaching the detector or fragmentation cell.
