Abstract: An online agricultural system manages and optimizes interactions of entities within the system to enable the execution of transaction and the transportation of crop products. The online agricultural system accesses historic and environmental data describing factors that may impact crop product transactions and/or transportation to determine market prices for crop products and crop product transportation. Responsive to receiving a request from an entity, the online agricultural system determines an optimal transaction for the entity, such as a price for selling a crop product, an available crop product for purchase, or a transportation opportunity to transport a crop product.

Abstract: In a method and system for viewer interaction with streaming media, a scene from a media presentation is displayed with a broadcasting device that includes an operating system level broadcaster interface overlay. The overlay generates an image frame from the scene. The image frame is sent to a viewer device. Viewer interaction parameters are received from a viewing device and a viewer interaction is displayed over a subsequent scene from the media presentation with the broadcaster interface overlay. On a viewing device an image frame from the media presentation is received from the broadcasting device. An operating system level viewer interface overlay is generated over the image frame and the image frame of the media presentation is displayed. Viewer interaction parameters are generated from a viewer interaction with the operating system level viewer interface overlay and sent to the broadcasting device.

Abstract: Systems and methods for hoisting a top drive of a drilling rig. An example system includes a hoisting system having a linear electric motor operable to raise and lower the top drive. An example method includes commencing operation of a processing device to cause operation of the linear electric motor to raise and lower the top drive. The linear electric motor may have a stator connected to and extending vertically along a mast of the drilling rig, and a rotor connected to the top drive and operable to move relative to the stator. The rotor may be connected to the top drive via one or more flexible lines.

Abstract: A linear encoder may be used to accurately determine a number of cartridges within a magazine. Further, using a set of magnetic sensors within a buffer tube of a firearm, it is possible to determine whether a cartridge is loaded within a chamber of the weapon and/or whether the firearm is jammed. The determination of cartridges within the magazine in conjunction with the determination of whether a cartridge is in a chamber of a firearm can give a user an accurate ammunition count. Further, the use of the linear encoder makes it possible to accurately determine the cartridge count when different cartridges are loaded into the magazine or when the magazine degrades in quality over time. Moreover, the ability for magazines to communicate with a firearm enables a user to determine a total available ammunition to the user in a single display without individually checking each magazine.

Abstract: A method for interconnecting components of a hydraulic fracturing system using flexible hose or pipe. The flexible hose or pipe can form a singular flow line which interconnects, for example, a pump and a manifold of the hydraulic fracturing system. Each end of the flexible hose or pipe can be tethered (using a safety restraint) to another component of the hydraulic fracturing system. In the event of a rupture or other failure, the safety restraint retains the tethered flexible pipes or hoses in a fixed position to prevent injury to personnel or damage to surrounding equipment.

Abstract: Technologies for detecting an error using a message authentication code (MAC) associated with cache line data and differentiating the error as having been caused by an attack on memory or a MAC verification failure caused by an ECC escape. One memory buffer device includes an in-line memory encryption (IME) circuit to generate the MACs and verify the MACs. Upon a MAC verification failure, the memory buffer device can analyze at least one of the historical MAC verification failures or historical ECC-corrected errors over time to determine if the error is caused by an attack on memory.

Abstract: Disclosed is a memory system that has a memory controller and may have a memory component. The memory component may be a dynamic random access memory (DRAM). The memory controller is connectable to the memory component. The memory component has at least one data row and at least one tag row different from and associated with the at least one data row. The memory system is to implement a cache having multiple ways to hold a data group. The memory controller is operable in each of a plurality of operating modes. The operating modes include a first operating mode and a second operating mode. The first operating mode and the second operating mode have differing addressing and timing for accessing the data group. The memory controller has cache read logic that sends a cache read command, cache results logic that receives a response from the memory component, and cache fetch logic.

Abstract: A digital signal processor includes analog to digital converters to convert an analog voltage to digital voltage in unit intervals of an analog signal. A decision feedback equalizer (DFE) determines a first level of a digital sum of a digital voltage in a first UI and digital voltages of adjacent UIs (taps). The DFE identifies predetermined sequences of levels of consecutive UIs that include the first level and selects one of the predetermined sequences to decode digital data encoded in the analog signal in the UI. The DSP may be programmable to include taps from UIs that may affect the first UI. The predetermined sequences may include levels of the digital sums of consecutive UIs of the analog signal. The predetermined sequences may be identified in a look-up table based on the first level.

Abstract: A game set includes tiles. Each tile has first and second surfaces, first and second sides, and first and second ends. The first surface of each tile includes a directional marking having a tail end and a leading end. The tail end of each directional marking is adjacent to only one of the first side, the second side, and the first end. The leading end of each directional marking is adjacent to only one of the first side, the second side, and the second end. When the tiles are arranged such that the leading end of the directional marking of one tile is adjacent to the tail end of the directional marking of another tile, the directional markings collectively define a single path that begins at the tail end of a first one of the tiles and terminates at the leading end of a last one of the tiles.

In the takeoff and landing power mode, both the power-optimized power source and the energy-optimized power source provide electrical power to the at least one electric motor.

Abstract: Data and error correction information may involve accessing multiple data channels (e.g., 8) and one error detection and correction channel concurrently. This technique requires a total of N+1 row requests for each access, where N is the number of data channels (e.g., 8 data row accesses and 1 error detection and correction row access equals 9 row accesses.) A single (or at least less than N) data channel row may be accessed concurrently with a single error detection and correction row. This reduces the number of row requests to two (2)—one for the data and one for the error detection and correction information. Because, row requests consume power, reducing the number of row requests is more power efficient.
