20120067019 | MECHANISM FOR CONTROLLING POSITION OF DISCHARGE BLOCKING FLAP FOR ROTARY MOWING DECK - A push and release operator control for selectively opening or closing the discharge blocking flap of a lawnmower. The first portion of travel of the actuator raises the discharge blocking flap toward its balance point. As the blocking flap reaches the balance point the actuator is released which allows the blocking flaps momentum to carry it through the balance point where gravity takes over to finish the travel. The actuator is reset by the blocking flaps motion after passing the balance point. Once the actuator is reset by the blocking flaps travel the same push and release of the actuator will return the blocking flap to it original starting position. | 03-22-2012 |

20110007754 | Flexible Hardware Checksum Generator - A traffic generator may include a scheduler to provide packet forming data defining a packet; a background engine to retrieve a packet template, the packet template including a first checksum mask, a first pre-sum, and a first address; a fill engine to generate content for variable-content fields of the packet for a payload portion of the packet in accordance with the packet forming data and the packet template; and a checksum engine. The checksum engine may include an accumulator that calculates a payload checksum for the payload portion of the packet and first logic circuits that compute a first checksum based on the first pre-sum, the first mask, and at least some of the payload checksum and the variable-content fields. Insertion logic may insert the first checksum into the packet at a position indicated by the first address. | 01-13-2011 |

20120303887 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR CACHING AND USING SCATTER LIST METADATA TO CONTROL DIRECT MEMORY ACCESS (DMA) RECEIVING OF NETWORK PROTOCOL DATA - Methods, systems, and computer readable media for caching and using scatter list metadata to control DMA receiving of network protocol data are described. According to one method, metadata associated with partially used scatter list entries is cached in memory of a scatter list caching engine. Data to be written to host system memory is received. The scatter list caching engine provides the metadata associated with partially used scatter list entries to a DMA controller to control the DMA writing of the data into host system memory. | 11-29-2012 |
