Abstract: A method for direct memory access (DMA) data transfer is adapted for a computer system having a microprocessor, a chipset, a memory with a physical region description (PRD) table and a DMA engine. In the method, a first group of PRD entries including at least two PRD entries of the PRD table by the DMA engine is fetched during a single PRD entry fetching cycle.

Abstract: A glide for walker leg includes a seat including a bottom cavity; a base on the seat and including a hole and a top groove; a hollow first sliding member adapted to mount on the base and including a first bore, a bottom rail slidably inserted into the groove, and a top first slope; a hollow second sliding member including a bottom second slope adapted to matingly, slidably mount on the first slope, a second bore, and an upper threaded section in the second bore; and a threaded fastener adapted to insert through the cavity, the hole, the first and second bores for threadedly securing to the threaded section. Driving the fastener will slide the second sliding member relative to the first sliding member by sliding the rail in the groove so as to urge the first and second sliding members against an inner wall of the leg.

Abstract: A basket that can be attached to a walking aid and that can store a large number of items but does not consume a large amount of space when not in use. The basket can be configured to be removably coupled to the walking aid. The basket includes a frame having sides and ends that are scissor hinges. The scissor hinges operate such that the frame sides can be position next to each other in a collapsed state and separated from each other in an expanded state so as to form an internal cavity to carry items. A flexible material is attached to the frame sides and scissor hinges thereby forming side walls and a bottom.
