    摘要: In a network router, a tree structure or a sorting network is used to compare scheduling values and select a packet to be forwarded from an appropriate queue. In the tree structure, each leaf represents the scheduling value of a queue and internal nodes of the structure represent winners in comparisons of scheduling values of sibling nodes of the tree structure. CBR scheduling values may first be compared to select a queue and, if transmission from a CBR queue is not timely, a packet may be selected using WFQ scheduling values. The scheduling values are updated to reflect variable packet lengths and byte stuffing in the prior packet. Scheduling may be performed in multiple stages.

    摘要: The method and system of the invention provide a variety of techniques for using a selected alias and a selected personal identification entry (PIE) in conjunction with use of a transaction card, such as a credit card, debit card or stored value card, for example. A suitable number or other identification parameter is selected by the. account-holder as an alias. The account-holder is then required to choose a PIE for security purposes. The alias is linked to the account-holder's credit card number via a database. When the account-holder enters into a transaction with a merchant, the physical card need not be present. The account-holder simply provides his or her alias and then the PIE. This can be done at any point of sale such as a store, catalog telephone order, or over the Internet. The alias and PIE are entered and authorization is returned from the credit card company.

    摘要: The present invention is a collapsible self-propelled chair on wheels that is lightweight in construction and easily collapsed, carried, stored and transported by public or private means. The chair performs the function of a wheelchair while avoiding the appearance of a traditional wheelchair thus avoiding the invalid stigma often associated with wheelchairs. It can be configured as an assistive mobility device to fill the unmet needs of aging healthy adults who wish to retain their independence and social interactions or a medical device to assist those with medical needs. Additional features such as an armrest, a footrest, or a reclining back are easily added during manufacture and because of the chairs uncomplicated design and duplicity of parts, it is very economical to manufacture.

    摘要: A chromatography column is normally filled with a slurry of media for operation. A piston normally compacts the slurry in the column. The piston moves through a cavity in communication with both a slurry inlet and slurry ports which are in communication with the interior of the chromatography column. A controller receiving inputs from at least one of position sensors and a pressure sensor directs movement of the plunger in an operational step selected from the group of a selected movement and up to a selected pressure.
