Abstract: A variable load unilateral and bilateral trap bar deadlift machine comprising: a frame having a base platform; a controller in communication with a display; a set of independent lever arms pivotally carried by the frame; a handle attached to each lever arm; a load controller in communication with each lever arm; wherein the controller is adapted to receive load input, determine a corresponding load setting for the load controller, transmit the load setting to the load controller, receive performance information such as grip strength, lift speed, power, weight, etc., and display the performance information on the display. Capabilities of the machine include analyzing performance data from each side of the body independently; use in combination with external devices such as force plates for further time series performance evaluation; and neuromuscular evaluation and training for populations such as high-performance athletes, tactical operators, rehabilitative patients, and more.

Abstract: A computerized system for collecting and normalizing health and physical performance data comprises: a central data store; multiple data sources communicating via a global network, each providing data in different structured formats; normalization modules translating data related to health, wellness, performance data and the like into a central format; and an end user system. The system includes a first data source associated with an exercise machine and a second data source, each with corresponding normalization modules. These modules translate data into a central format for storage in the central data store. The end user system retrieves translated data, processes it, and provides results to users. The system may include a cloud storage for data aggregation and a customized interface for different industries.

Abstract: According to one exemplary implementation, a method for use by a global illumination system including a hardware processor includes identifying, using the hardware processor, a first interior vertex of multiple first interior vertices of a light path, the first interior vertices being situated within a volume having a refractive boundary. In addition, the method includes determining, using the hardware processor, a surface vertex of the light path at the refractive boundary, and determining, using the hardware processor, a linear direction from the surface vertex to a light source of the light path. The method also includes determining, using the hardware processor, one or more second interior vertices for completing the light path by constructing a path from the surface vertex to the first interior vertex, based on the linear direction, the surface vertex and the first interior vertex.

Abstract: A rail car cover system that includes a rail car, a first cover section and a second cover section. The rail car has an opening. The first cover section is operably attached to the rail car. The first cover section includes a first closure mechanism. The second cover section is operably attached to the rail car. The second cover section includes a second closure mechanism. The first cover section and the second cover section are both movable between a closed configuration and an open configuration. When in the closed configuration, the first closure mechanism engages the second closure mechanism to maintain the first cover section and the second cover section in the closed configuration.
