Abstract: A hand-held ergonomic material-handling device capable of moving heavy objects, such as large waste containers and other large objects requiring mechanical assistance. The ergonomic material-handling device can be used with neutral postures of the back, shoulders, wrists and knees, thereby reducing potential injury to the user. The device involves two key features: 1) gives the user the ability to adjust the height of the handles of the device to ergonomically fit the needs of the user's back, wrists and shoulders; and 2) has a rounded handlebar shape, as well as the size and configuration of the handles which keep the user's wrists in a neutral posture during manipulation of the device.

Abstract: A memory controller (42) supports a mode known as continuous page mode. The memory controller (42) is coupled to a pipelined internal bus and provides control signals to an external bus to control a memory such as a dynamic random access memory (DRAM) (43). The memory controller (42) compares the page portion of a next address to the page portion of the current address. If the addresses match, the memory controller (42) keeps the page open for the next cycle. However if the addresses do not match, or if the next address is not valid at this same point in time during the first access, the memory controller (42) closes the page during the first cycle. The memory controller (42) performs continuous page mode without incurring a penalty when the page is closed.
