The merchant (130) can then determine whether to accept the payment instrument tendered or deny credit and require another payment instrument. An architecture that provides support for additional message types that are not SET compliant is provided by a preferred embodiment of the invention. A server communicating bidirectionally with a gateway (140) is disclosed. The server communicates to the gateway (140) over a first communication link, over which all service requests are initiated by the server. The gateway (140) uses a second communication link to send service signals to the server. In response to the service signals, the server initiates transactions to the gateway (140) or presents information on a display device.

Title: Plasmids for plant transformation and method for using the same
Inventor: HOEKSTRA SIETSKE
IPC: A01H5/00
Filed: 1998-06-29
Abstract: This invention relates to the Agrobacterium mediated plant transformation, especially to transformation of plants with T-DNA, where read-through at the borders is prohibited. This can be done by inhibition of transfer of vector DNA to the plant cell by creating DNA binding sites outside the T-borders, but also to insert a coding sequence outside the T-borders which, whether or not in cooperation with genes from the host plant or genes cotransferred, are toxic to plants so that there is counterselection for plants with superfluous vector-DNA.

Title: Visualization and self-organization of multidimensional data through equalized orthogonal mapping
Inventor: MENG ZHUO
IPC: G06N3/04
Filed: 1998-12-14
Abstract: The subject system provides reduced-dimension mapping of pattern data. Mapping is applied through conventional single-hidden-layer feed-forward neural network with non-linear neurons.  According to one aspect of the present invention, the system functions to equalize and orthogonalize lower dimensional output signals by reducing the covariance matrix of the output signals to the form of a diagonal matrix or constant times the identity matrix. The present invention allows for visualization of large bodies of complex multidimensional data in a relatively "topologically correct" low-dimension approximation, to reduce randomness associated with other methods of similar purposes, and to keep the mapping computationally efficient at the same time.

Title: Simultaneous slicing and washing of vegetables
Inventor: BROWN DANIEL E
IPC: A23L19/00
Filed: 2000-08-02
Abstract: Simultaneous slicing and washing of relatively firm raw vegetable or fruit products is accomplished in a vat of water into which a slicer apparatus is positioned such that the slices are formed and discharge directly into the water and free fall. An inclined takeout conveyor serves to receive the slices and remove them from the water. A circulating water current and fluid jets urge the slices to disperse onto the conveyor. A spray of water removes residual vegetable matter from the slice surfaces before leaving the takeout conveyor for further processing.

Title: Folding sawhorse with locking shelf
Inventor: DURAPAU RICK
IPC: B25H1/06
Filed: 2000-08-11
Abstract: A folding sawhorse of the type comprising two trestle like frames that are hingedly connected at their tops. The shelf is hingedly attached to a lower strut of one frame and slidably attached to the legs of the opposite frame. The slidable attachment is by means of pairs of pins that are secured to one end of the pivoting shelf and are also yoked to longitudinal ridges that are in the legs of the opposite frame. To open the sawhorse from its closed, storage position, the frames are spread apart slightly, thereby allowing gravity to pull the shelf downwardly and concurrently causing the frames to spread outwardly to their open, working position. The sawhorse will stay in this locked open position without any additional latching mechanisms until the close procedure is initiated. To close the sawhorse for storage, a light upward pressure is applied on the edge of the pivoting shelf, causing it to move upwardly and concurrently causing the frames to pivot inwardly toward each other to their closed storage position.
