Abstract: Disclosed are various embodiments for providing extrinsic data relevant to a video content feature. In one embodiment, where a single cast member performs as multiple characters in the video content feature, the extrinsic data may include character images for each character played by the cast member. In another embodiment, where multiple generic images of a cast member are available, a particular generic image is selected to be included in the extrinsic data according to a measure of relevancy of the generic image to the video content feature. In another embodiment, when a generic image of a cast member is unavailable, an image of the cast member in character is included in the extrinsic data.

Abstract: A crane assembly includes a main body, a boom, a hoist, a sheave, a hook assembly including a hook, a cable, and a projection. The boom extends from the main body and includes a tubular main section and a tubular extension section telescopically nested within the tubular main section. The boom has a first end pivotally coupled to the main body. The hoist is coupled to at least one of the first end of the boom and the main body. The sheave is disposed at an opposing second end of the boom opposite to the main body. The cable extends from the hoist, along the length of the boom, over the sheave, and downward to the hook assembly. The projection extends outward from the boom and toward the main body.

Abstract: An improved tessellation graphics pipeline that obviates that use of early stage vertex shaders and hull shaders and allows greater efficiency and flexibility. Embodiments provide a graphics pipeline beginning with a tessellator that may obtain tessellation factors in any manner such as reading from a memory of factors provided by a developer or computing the factors using a compute kernel. In some embodiments, a single vertex shader may follow the tessellator and perform all the necessary vertex shading for the pipeline. Furthermore, in some embodiments, a compute kernel is used to generate the tessellation factors. The compute kernel provides flexibility that allows its employment for some graphic portions and not others. In addition, the streamlined pipeline facilitates the efficient use of scaling to determine tessellation factors for the same graphic portion at different camera distances or desired levels of replication of the mathematical model.

Abstract: Disclosed are various embodiments for presenting a user interface in association with video content features. A video content feature is rendered on at least one display. A current scene in the video content feature is determined. Cast members are determined who have appeared in the current scene from a beginning of the current scene up to a current time in the current scene. A user interface is rendered on at least one display. The user interface includes selectable cast member components that each include an image of a cast member, a name of the cast member, and a name of a respective character performed by the cast member.

Abstract: A system decouples the source code language from the eventual execution environment by compiling the source code language into a unified intermediate representation that conforms to a language model allowing both parallel graphical operations and parallel general-purpose computational operations. The intermediate representation may then be distributed to end-user computers, where an embedded compiler can compile the intermediate representation into an executable binary targeted for the CPUs and GPUs available in that end-user device. The intermediate representation is sufficient to define both graphics and non-graphics compute kernels and shaders. At install-time or later, the intermediate representation file may be compiled for the specific target hardware of the given end-user computing system.

Abstract: Disclosed are various embodiments for presenting a timeline interface in association with video content features. A user interface is rendered on a display, where the user interface includes selectable cast member components and a timeline component. The timeline component corresponds to a video content feature and visually segments it into scenes. A user selection of a particular selectable cast member component is received, and a subset of scenes in which a corresponding cast member performs is determined based at least in part on extrinsic data. The timeline component is updated to visually indicate the subset of scenes.

Abstract: A thrust apparatus for a rod string. The apparatus has a stationary frame, a thrust frame with a rod gripper, two hydraulic cylinders and two rams in fluid communication with the hydraulic cylinders. During low-load operations, the hydraulic cylinders act alone, providing the load to the grippers to pull or push the rod string. When higher loads are required, a check valve is activated, allowing fluid from the hydraulic cylinders to activate the rams. The rams provide additional force to the grippers, and may be activated without mechanical or significant hydraulic changes to the apparatus.

Abstract: Methods, systems and devices are disclosed to examine developer supplied graphics code and attributes at run-time. The graphics code designed for execution on a graphics processing unit (GPU) utilizing a coding language such as OpenCL or OpenGL which provides for run-time analysis by a driver, code generator, and compiler. Developer supplied code and attributes can be analyzed and altered based on the execution capabilities and performance criteria of a GPU on which the code is about to be executed. In general, reducing the number of developer defined work items or work groups can reduce the initialization cost of the GPU with respect to the work to be performed and result in an overall optimization of the machine code. Manipulation code can be added to adjust the supplied code in a manner similar to unrolling a loop to improve execution performance.

Abstract: A control system for a capstan assembly for use with a winch during wire rope payout. The control system comprises a sensor that detects the rope when it is in a predetermined position indicative of tension placed on the rope by an operator. The control system further comprises an actuator for rotating the capstans such that the wire rope is paid out from the winch when the actuator is in a first position. The control system causes the capstans to rotate and the wire rope to pay out when the rope is in the predetermined position and the actuator is in the first position. The control system ceases rotation when the actuator is removed from the first position or the rope is no longer in the predetermined location.
