    摘要: Exemplary embodiments of the present invention are directed towards systems and methods for providing improved access to vehicles for physically challenged individuals. In one exemplary embodiment, a wheelchair access system for a vehicle is provided. The system includes a first track and a second track, the first and second tracks being located on opposite sides of the frame assembly. The system also includes a ramp formed of a porous structural member disposed between a first skin member and a second skin member. The ramp has a first edge portion with one or more rollers attached thereto and a second edge portion having one or more rollers attached thereto. The one or more rollers on the first and second edge portions travel within the first and second tracks, respectively, of the frame assembly. The system further includes a drive motor engaging a first rotatable drum member and a second rotatable drum member. The drive motor is configured to rotate the first and second drum members in first and second directions based on a direction of a current flowing through the drive motor. The system still further includes a first cable engaging the first drum member and a second cable engaging the second drum member. The first and second cables are coupled to the ramp such that the first and second cables move the ramp from a stowed position to a deployed position during rotation of the first and second drum members in the first direction.

    摘要: A printer controller for processing print data includes a data processor, direct memory access controller, first and second memories with corresponding first and second transfer data busses. A bus switch selectively connects the first and second data transfer busses. When uncoupled, the data processor accessed the said first memory via the first data transfer bus and the direct memory access controller may independently accesses the second memory via the second data transfer bus. When connected, either the data processor or the direct memory access controller may access either memory to the exclusion of the other. This permits better allocation of data transfer bandwidth in the memory controller.

    摘要: A multilevel hierarchical least recently used cache replacement priority in a digital data processing system including plural memories, each memory connected to said system bus for memory access, a memory address generator generating addresses for read access to a corresponding of the memories and a memory cache having a plurality of cache entries, each cache entry including a range of addresses and a predetermined set of cache words. During each memory read the comparator compares the generated address with the address range of each cache entry. If there is a match, then the cache supplies a cache word corresponding to the least significant bits of the generated address from the matching cache entry. If there is no such match, the generated address is supplied to the memories and a set of words is recalled corresponding to the generated address. This set of words replaces a least recently used prior stored memory cache entry having the lowest priority level. The priority level for each cache entry may be recalled from a cache priority level look-up table or entered from an instruction via coding in opcode bits or a priority setting instruction. In an alternative embodiment this technique is used with a memory configuration cache storing memory access parameters for corresponding address ranges enabling adaption to plural memories requiring differing sets of memory access parameters.

    摘要: Novel cementitious systems comprised of gypsum, calcined clay, and clinker consisting essentially of hydraulic calcium silicates are disclosed which have the following properties: (1) a water demand of less than about 33% nc; (2) one-day strengths of at least about 1000 psi; and (3) low alkali functionality. By increasing the amount of calcined clay, the resulting cementitious system will sequentially gain the following properties: (1) alkali non-reactiveness; (2) alkali resistance; and (3) low chloride permeability. Novel methods of preparing the novel cementitious systems of this invention are also disclosed. The novel methods not only reduce production costs by decreasing fuel and raw material consumption, but they also allow the cement producer to proactively address significant environmental concerns related to the manufacturing process.
